Jay Hemnani ac35c7dcbb Default the day of the month to 1 in strptime/1 (#3679) 
A format without %d left the day of the month at 0, which mktime and
todate read as the last day of the previous month, and the weekday was
wrong for dates in January and February of 1900 and 2100.

Start parsing from the 1st, so a format without a day now gives the
first of the month, and a time-only format no longer outputs the 8 and
367 placeholders for the weekday and day of the year. This also fixes
the weekday of dates in January and February of 1900 and 2100.

Michiel van Slobbe 864d769d88 Implement ascii_downcase and ascii_upcase in C (#3689) 
Both were defined as explode | map(...) | implode, which took 4 seconds
on a 10 MB string, about 90 times as long as parsing it.

Change the case of A-Z or a-z a byte at a time in C, copying multibyte
UTF-8 sequences unchanged, so the output stays the same and the 10 MB
case now takes about 60 ms including parsing. On a non-string input the
error now names the function, "ascii_downcase input must be a string",
instead of "explode input must be a string".

Huang-404-Q bd56a74562 Fix halt_error adding a newline to non-string output (#3694) 
The manual says halt_error prints its input with no decoration, not
even a newline, but non-string values such as {"a":"xyz"} were printed
with a trailing newline.

Dump non-string values to JSON and print them the same way as strings,
so {"a":"xyz"} | halt_error(1) now writes exactly {"a":"xyz"} to stderr.

itchyny da4da65c0c docs: rewrite the tutorial (#3631) 
The tutorial is where most people meet jq, but it was missing key
filters like select and abbreviated commands in ways that are hard for
beginners to follow.

Grow the page from 7 examples to 24, newly covering -r and -c, chained
paths and slicing, map, sort_by, group_by, select, test, to_entries,
from_entries, with_entries, string interpolation and @tsv. The sample
data is pinned with the API's until parameter and the outputs avoid
GitHub account data, so running the commands gives exactly the output
shown.

Douglas Adolph 53bbd4a3f9 docs: add ldconfig and make clean to the README source build (#3692) 2026-10-24 09:33:07 +09:00
qodelicious 49fbca1242 docs: explain that semicolons separate function arguments (#3685) 
The manual's "Defining Functions" section shows only one-argument
functions, so it never says how to pass more than one. This adds a short
paragraph: arguments are separated by `;` in both `def f(a; b):` and
`f(.x; .y)`, and `f(.x, .y)` instead calls a one-argument `f` with the
filter `.x, .y`. It also adds an example for each. `tests/man.test` and
`jq.1.prebuilt` are regenerated.

Fixes #2163

qodelicious e440cccc0a docs: fix arithmetic update-assignment equivalence (#3682) 
The manual said `a op= b` is equivalent to `a |= . op b`. It is actually
equivalent to `(b as $b | a |= . op $b)`: the right-hand side gets `.`
as input, not the value being updated, and each value it outputs gives a
separate result.

This updates the description and adds two examples, `.a += .b` and `.a
+= (1,2)`. `tests/man.test` and `jq.1.prebuilt` are regenerated.

Fixes #2119, fixes #2407

mika 94b00aa807 test: check that --run-tests reports failing tests (#3650) 
Nothing tested that jq --run-tests exits with status 1 when the
tests fail, so a failure could have been reported as a pass.

Add shell tests with incorrect, missing and extra output that check
both the exit status and the reported message, such as "Insufficient
results", along with a passing control. Under Valgrind, memory errors
exit with status 99 so they are not mistaken for a test failure.

Léane GRASSER 175b8e3c51 docs: update quoting rules for PowerShell 7.3+ (#3649) 
The manual recommended backslash-escaped double quotes inside the jq
program for all PowerShell versions, but since PowerShell 7.3 native
command arguments are passed with standard quoting by default, so the
backslashes reach jq literally.

Describe the quoting rules separately for Unix shells and PowerShell
7.3+, for older PowerShell and Windows PowerShell, and for cmd.exe, and
update the examples to match.

fhgffy afa23a53cd Keep the sign of zero when negating a number literal (#3662) 
Since jq 1.8.0, negating a number literal computed 0 - x, so -0 and
0 | -. printed 0 while (0+0) | -. printed -0.

Flip the sign bit with decNumberCopyNegate() instead, so -0 prints -0
again as it did in jq 1.7, and -(-0) is still 0.

Michiel van Slobbe 852c4d6096 Improve performance of UTF-8 validation (#3675) 
jvp_utf8_next() had a fast path for ASCII, but it is not inlined into
its callers, so every byte of a string cost a function call.

Move the end check and the ASCII case into a static inline function in
jv_unicode.h and keep the rest out of line. This speeds up parsing of
string-heavy input by up to 1.17x and string functions such as length,
explode and @html, with the same output for every input.

Dmitri Vereshchagin 633ae6058a Disable colored output on a dumb terminal (#3552) 
Enable colored output by default only when the TERM environment variable
is set to a value other than dumb, as git and grep do, so that users no
longer need to pass -M or set NO_COLOR on terminals that cannot display
escape sequences. Colored output is now disabled not only for TERM=dumb
but also when TERM is unset or empty. The -C option still enables colors
in all these cases. On Windows, colored output is still decided by
ANSICON and the console mode, and TERM is not checked.

Doha Nam 6b53f80311 Fix strftime/1 and strflocaltime/1 to allow an empty result (#3670) 
These functions failed with "unknown system failure" whenever strftime()
returned 0 for a non-empty format, but 0 also means the format expands to
an empty string, as %p does in a locale without AM/PM.

Prepend a character to the format and trim it from the result, so that 0
can only mean the result is too long. Now 0 | strflocaltime("%p") gives
"" in fr_FR.UTF-8, and a result that is still too long fails with
"result too long" error instead. The size limit is unchanged.

Michiel van Slobbe 80fc7a169d Skip to the next RS after a parse error in --seq mode (#3654) 
In --seq mode, a parse error was reported as "need RS to resync", but
parsing continued in the middle of the broken text, so fragments of it
were reported as more errors or output as values.

Set the parser state to wait for the next RS after resetting the parser,
instead of before, so that the rest of the broken text is skipped as
RFC 7464 recommends.

Hugohong258 611c575a97 docs: add simple and nested update-assignment examples (#3664) 2026-10-12 00:24:32 +09:00
Michiel van Slobbe b904884b94 Improve performance of string output (#3643) 
Printing a string wrote each character with a separate call, one
fwrite() per character, or one jv_string_append_buf() for tojson and
tostring, which made output of string-heavy data slow.

Scan ahead for the next byte that needs escaping and write the run of
bytes before it with a single call, without changing the output.
Printing strings is now significantly faster, most of all for long
strings with few characters to escape, and the same applies to tojson
and tostring. With --ascii-output, text that is almost all non-ASCII is
about the same speed, since nearly every byte is escaped anyway.

itchyny a5323a369c Fix assertion failure on too many parameters in a nested function (#3663) 
A call passing more than 4095 arguments at the start of a nested
function body aborted jq after reporting the compile errors, with
"Assertion failed: (nemb > 0 && sz > 0), function jv_mem_calloc" and
exit status 134.

Stop compiling a function before its bytecode is allocated when it has
compile errors, since the bytecode is only generated and used when
compilation succeeds. jq now prints the same compile errors followed by
"jq: 2 compile errors" and exits with status 3, as it does for other
compile errors, instead of crashing.

qodelicious 04042494cf Exit with the given status for negative halt_error codes (#3660) 
halt_error with a negative exit code did not exit with that code. The
code collided with the internal status values for null or false output
and for no output, so halt_error(-1) exited with 0, or with 1 under
--exit-status.

Keep the low 8 bits of a negative code, as exit(3) does on POSIX
systems, so halt_error(-1) now exits with 255 and halt_error(-2) with
254, the same with or without --exit-status. Under --exit-status this
replaces the previous absolute value, so halt_error(-2) used to exit
with 2 and halt_error(-255) with 255, and they now exit with 254 and 1.

omkar bhor a8e6d5f871 Fix undefined behavior on out-of-range array index in has() and del() (#3560) 
Converting a double outside the int range to int is undefined behavior,
and has() and del() did it on array indices like infinite or 1e10, which
UBSan reports as "inf is outside the range of representable values of
type 'int'". Only NaN was guarded against.

Clamp the index to the int range in has(), as getting and setting array
elements already do, and drop out-of-range indices in del() before they
are converted. Such indices can never refer to an element, so has()
returns false and del() leaves the array unchanged, the same as for
indices past the end of the array. Valid indices deleted together with
out-of-range ones, as in del(.[0, 1e10]), are still deleted.

neil dbbae0dee3 Add FreeBSD and NetBSD CI (#3600) 
Add a BSD workflow with FreeBSD and NetBSD jobs that run the same build
and tests as the linux job, each inside a VM booted under QEMU on an
ubuntu-latest runner. The tests/shtest $NO_COLOR pty checks are now
skipped on NetBSD, as they already are on SunOS.

itchyny e001deb4cf Strip UTF-8 BOM at the start of each input file (#3657) 
The UTF-8 BOM was stripped only at the start of the parser stream, but jq
feeds all input files into a single parser, so a BOM at the start of the
second and later files reached the parser as content and failed with a
confusing "Invalid numeric literal" error. Strip it in the file readers
instead, at the start of each input file including stdin, and in
jv_load_file.

This also strips the BOM for raw input, so -R and --rawfile no longer
yield a leading U+FEFF, and a BOM at the start of a -f program file or an
imported module is now accepted rather than reported as a syntax error.
In exchange, "\uFEFF1" | fromjson is now a parse error, since a U+FEFF
inside a string is content rather than an encoding marker, and the
dedicated "Malformed BOM" error is gone.

itchyny 17b87d25c7 Drop the date from the committed man page (#3659) 
The date in the .TH line of jq.1.prebuilt changed whenever the manual was
regenerated in a new month, causing merge conflicts between pull requests
that touch the manual, and it did not reflect the release date anyway.
Generate the committed man page without a date.

Stamp the date into jq.1 at build time instead, taking it from the current
commit, or from SOURCE_DATE_EPOCH where that is set, so that release
tarballs and distribution builds still carry one and the behaviour added
in #3514 is kept. Write it in UTC and in ISO 8601 rather than the previous
"%B %Y", for which mandoc reports "cannot parse date, using it verbatim".

itchyny fd25c3e720 Parse the full ISO 8601 grammar in fromdateiso8601 (#3617) 
`fromdateiso8601` was `strptime("%Y-%m-%dT%H:%M:%SZ") | mktime`, which
accepts only one of the many representations ISO 8601 permits. strptime
cannot be extended to cover the rest portably, since it has no specifier
for fractional seconds and glibc discards `%G` and `%V`.

Replace it with a parser in src/iso8601.c that handles basic and extended
representations, ordinal and week dates, fractional seconds, offsets and
date-only input. It uses integer arithmetic instead of `time_t`, so the
results no longer depend on the platform.

This is stricter than before. Impossible dates like `2015-02-30`, which
`mktime` used to normalize into March, and unpadded components like
`2015-3-5T6:00:00Z` are now errors. So is any trailing input, including
whitespace. Leading whitespace is rejected too; before, glibc skipped it
and macOS did not. A leap second now maps to the second before it rather
than the next minute. The error message has changed, and the result can
now be non-integer.

A4-Tacks a19efdd45d Parse ?// as ? and // outside destructuring patterns (#3593) 
The lexer returned a single ALTERNATION token for `?//`, so any `?`
followed by `//` was consumed by it, and `.name?//"unknown"` failed
to parse even though they read as the optional operator followed by
the alternative operator.

Drop the lexer rule and spell the destructuring alternative operator
as `'?' "//"` instead. So `x ?// y` now parses as `x? // y`, while
`. as [$a] ?// [$b] | ...` keeps its meaning. Note that `?` and `//`
may now be separated by whitespaces inside a pattern.

Artem Lytkin 9a75bb0d43 Improve performance of join/1 on large arrays (#3639) 
join/1 folded each element as `(acc + $x) + elem`, with the element
branch ending in `.//""`. Both leave a second live reference to the
accumulator: the nested + feeds the same `.` to both operands, and the
`//` leaves a forkpoint below it on the stack. `jvp_string_append`
therefore cannot grow the accumulator in place, and copies the whole
string once per element.

Pipe `acc + $x` into `. + elem` and drop the `//`, since adding null to
a string is already a no-op. join/1 is now linear: joining 8000
strings of 1000 chars goes from 6.5s to 0.06s, with output and error
messages unchanged.

Brandon 32580f5d83 Prefer getentropy() over arc4random() to seed the string hash (#3629) 
glibc's arc4random() aborts with "Fatal glibc error: cannot get entropy
for arc4random" when the kernel lacks getrandom(2), so jq died on
startup on older kernels once 0c7d133 began seeding the hash on every
run.  getentropy() merely returns -1/ENOSYS there, so prefer it, and
route its failure through the existing `/dev/urandom` path - which works
on precisely those kernels -- instead of a guessable `getpid() ^ time()`.

itchyny df24981307 Fix reduce to preserve its input across init backtracking (#3633) 
`reduce f as $x (init; update)` evaluated `f` against a stack slot
that forkpoints created while evaluating `init` restore. Both the
`DUPN` opening the reduction loop and the `LOADVN` retrieving the
result pop that slot destructively, nulling it out, so an `init`
that backtracks (e.g. `0, 0`) made `f` see `null` and fail with
"Cannot iterate over null".

Duplicate the input before the `FORK` instead of inside the loop,
and drop the leftover copy with `POP` once the loop is exhausted.
The slot left live at the `FORK` is then a block pushed after
`init` completed, which no earlier forkpoint can reach, so nulling
it is harmless. This is the same approach `gen_foreach` has used
since c70ae1a.

`DUPN` had no other user, so remove the opcode.

A4-Tacks 4beed4e01a perf: avoid the intermediate array in from_entries (#3626) 
Define `from_entries` as `add(.[] | f) // {}` instead of
`map(f) | add // {}`. Since `add(f)` is `reduce f as $x (null; . + $x)`,
both fold the same values in the same order from the same seed, so the
only difference is that the array of single-key objects built by `map`
is never materialized.

Measured with both the generator and the result suppressed, so that only
the `from_entries` work differs: 6-15% less user time across input shapes,
which is 10-24% of what `from_entries` itself costs. For inputs above
roughly a thousand entries, peak RSS drops by 37%, around 80% of the
memory `from_entries` adds on top of its input; a 1,000,000 entry array
goes from 1064 MiB to 672 MiB.

itchyny 12cdd950e9 Register imported libraries in dependency order (#3620) 
block_mark_referenced walks the joined block backwards and skips the
body of any definition not yet marked referenced, so a library must
precede its importers.  f58787c41 registered a library before walking
its dependencies, to have somewhere to keep the `loading` flag, which
reversed that order and made block_drop_unreferenced free definitions
that are still referenced through bound_by.

Keep the libraries being loaded on a stack threaded through the
load_library frames instead, so registration can move back after the
dependency walk.

itchyny e371bfaa92 Implement range/3 in C for consistent error handling (#3267) 2026-09-18 22:20:58 +09:00
Bumsu Hyeon dd409de28d Use WriteConsoleW() in priv_fwrite() too (#3607) 
jq dumps JSON to the Windows console as UTF-16 with WriteConsoleW(),
but priv_fwrite() still writes the raw UTF-8 bytes with WriteFile(),
which the console decodes with its output code page.  So `jq .k` prints
non-ASCII correctly while `jq -r .k` prints mojibake, and the same goes
for -j, --raw-output0, --seq, halt_error and the `stderr` builtin.

The tty flag is computed once, from stdout, and passed to writes aimed
at stderr too, so ask the handle instead: with stdout on a console and
stderr redirected, WriteConsoleW() failed on the file handle and the
output was dropped.

One byte-level change: with stdout on a console and stderr redirected,
halt_error and the `stderr` builtin now go through the CRT, so bare LF
becomes CRLF and an existing CRLF becomes CR CRLF.  Use -b for
byte-exact output on that stream.

JUSHUANGHUI LI 7422e8c914 docs: clarify ownership of jv arguments and results (#3627) 
The ownership comment in `jv.h` currently says every `jv_*` function
except `jv_copy` consumes its input. Several accessors and
object-iteration functions borrow their arguments instead, which makes
that guidance misleading for callers and language bindings.

Document the borrowing exceptions beside their declarations, including
numeric helpers and `jv_show`. Clarify that returned `jv` values are
owned, while the pointers returned by `jv_string_value` and
`jv_number_get_literal` belong to their input values. This changes
comments only.

Hugohong258andHugohong258 1b4109b0d0 docs: clarify that prebuilt downloads are standalone executables (#3632) 
State explicitly in the README and download page that the
platform-specific prebuilt files are standalone executables, not
archives. Include the rename and executable-permission step for macOS
and Linux in the README.

Addresses #2956. Source archives are not described as executables.

Validation: the official `docs/build_website.py` completed and the
generated download page contains the new guidance. Used a Python venv
with the site's required rendering packages; restored the Windows
checkout's manual symlink in a temporary build copy only. jq itself was
not built or tested for this documentation-only change.

itchynyandDirk Müller 46d1da3094 Tighten string length bounds and propagate invalid jv in implode 
The bound added in CVE-2026-32316 (e47e56d22) still allowed
`sizeof(jvp_string) + (currlen + len) * 2 + 1` to wrap `size_t` on
32-bit platforms. Tighten the threshold so the final allocation
fits in 32-bit `size_t`.

Also break out of `jv_string_implode` and `f_string_implode` once
`jv_string_append_codepoint` returns an invalid `jv`; otherwise the
next iteration triggers the assertion in `jvp_string_ptr` (or
invokes undefined behavior under `-DNDEBUG`).

Fixes CVE-2026-54679.

itchyny e987df0d46 Fix heap-buffer-overflow in raw file loading 
When `jv_string_append_buf` overflows the string length limit,
it returns an invalid `jv`; `jv_load_file` then re-entered it
on the invalid value and overran the heap. Break out of the loop
once the value is invalid.

itchyny a829f678f3 Fix one-byte over-read in BASE64_DECODE_TABLE (#3547) 
The table was declared with 255 entries but indexed by an unsigned
char, so the decoder would read one byte past the array for input
bytes equal to 0xFF. Through jq's normal input paths the over-read
is unreachable because invalid UTF-8 bytes are normalized to U+FFFD
before reaching @base64d, but the table is still wrong at the C
level and reachable by libjq callers that construct strings via
the C API without UTF-8 validation.

Yu-Fu Fu 7122866869 Guard deep structural equality and comparison recursion (#3539) 
jv_equal and jv_cmp overflows the C stack on deeply nested
input. Cap recursion at 10000 with -1 / INT_MIN sentinels;
operators that compose user expressions surface this as
"Equality check too deep" / "Comparison too deep".

itchyny f58787c418 Detect circular module imports to prevent stack overflow 
jq used to recurse without bound on mutual or self-referential
`import` declarations, exhausting the stack. Track each library's
load state with a `loading` flag set before its dependencies are
processed; a recursive reference to an in-progress library now
reports "circular import of X".

Fixes CVE-2026-44777.
 2026-05-11 20:41:38 +09:00
itchyny 9d223f153c Reject embedded NUL bytes in module import paths 
jq accepts embedded NUL bytes at the language level but resolves
module import paths through NUL-terminated C strings, so the path
validated by policy or audit code could differ from the on-disk
path jq actually opens. Pass jv through gen_import so the AST
preserves the original bytes, and reject embedded NULs in
validate_relpath.

Fixes CVE-2026-43895.
 2026-05-09 17:08:43 +09:00
itchyny 9761ceb7d6 Reject numeric literals longer than DEC_MAX_DIGITS (999999999) 
A signed-int overflow in decNumber's D2U macro lets huge literals
write attacker-controlled bytes past a stack buffer. Cap the length
before calling decNumberFromString, and pre-slice long strings in
jv_dump_string_trunc so the resulting error message doesn't itself
allocate a multi-GiB buffer.

Fixes CVE-2026-43894.

itchyny e47e56d226 Fix heap buffer overflow in jvp_string_append and jvp_string_copy_replace_bad 
In `jvp_string_append`, the allocation size `(currlen + len) * 2` could
overflow `uint32_t` when `currlen + len` exceeds `INT_MAX`, causing a small
allocation followed by a large `memcpy`.

In `jvp_string_copy_replace_bad`, the output buffer size calculation
`length * 3 + 1` could overflow `uint32_t`, again resulting in a small
allocation followed by a large write.

Add overflow checks to both functions to return an error for strings
that would exceed `INT_MAX` in length. Fixes CVE-2026-32316.

Vladimír Marek 9f778b4cb5 Add Solaris support (#3515) 
I love jq :) So while updating the version we ship in Solaris I have
tried to modify stuff to make everything work out of the box. Just

```
autoreconf -fiv
./configure
gmake
gmake check
```

I also went ahead and created Solaris test action should you be
interested in having it too. The changes are not extensive and I have
tried to comment them nicely in each commit. Hopefully that's enough.

Thanks for jq!

Peter KjellerstedtandPeter Kjellerstedt 27f417f481 Support building with --disable-maintainer-mode and source != build dir (#3518) 
If --disable-maintainer-mode is enabled, then the rules for generating
parser.[ch] and lexer.[ch] did nothing. This worked fine if the source
and build directories are the same as the pre-generated parser.c and
lexer.c files would suffice. However, if the build directory is not the
same as the source directory, then the rest of the Make rules expect
parser.[ch] and lexer.[ch] to have been created in the build directory
if their source files (parser.y and lexer.l) are newer than the target
files, which can happen in case the source is fetched using Git.

Avoid the problem by copying the files to the build directory if needed.

When a module fails to parse as a library, `load_library` cached the

the cached invalid block and pass it to `block_bind_library`,
triggering the assertion failure. Skip caching the block when there
are parse errors to avoid this problem.

Mattias Wadman 5e159b34b1 Fix GHSA-f946-j5j2-4w5m stack-overflow by limit regex parse depth 
Was detect by AFL build but it's unsure if possible to trigger in non-fuzz build.

Oniguruma has a default limit of 4096 but this is not be low enough to
protect from stack-overflows in some builds like with AFL where it seems
to use more stack space. A limit of 1024 should be enough usage-wise
and also give more margin.

itchyny c6e041699d Fix heap buffer overflow when formatting an empty string 
The `jv_string_empty` did not properly null-terminate the string data,
which could lead to a heap buffer overflow. The test case of
GHSA-p7rr-28xf-3m5w (`0[""*0]`) was fixed by the commit dc849e9bb7,
but another case (`0[[]|implode]`) was still vulnerable. This commit
ensures string data is properly null-terminated, and fixes CVE-2025-48060.

Thalia Archibald 9ac6ddae22 Fix whitespace in number parsing (#3195) 
* Handle input errors for --indent

Handle malformed and overflowing arguments. Also, forbid leading and
trailing spaces to match the behavior of tonumber from commit ce0e788
(improve tonumber/0 performance by parsing input as number literal,
2024-03-02).

* Do not skip leading whitespace in jvp_strtod

`jvp_strtod` skips leading whitespace, but its decnum counterpart
`decNumberFromString` (called within `jv_number_with_literal`) does not.
Those two are called interchangeably, so it leads to inconsistent
behavior depending on whether the decnum feature is enabled.
Additionally, `classify`, used in the token scanner, only considers
[ \t\n\r] to be whitespace, but `jvp_strtod` consumes the larger set
[ \t\n\v\f\r], so those extra characters are considered literals.

Changing this deviates from the behavior of `strdod` from <stdlib.h> and
is technically a breaking API change, since it is a public symbol.

itchyny aaace5432a Fix parser to allow binary operators for binding syntax (#3326) 
Previously, the precedence of `as` binding was higher than the binary
operators. This results in unexpected behaviors, `1 + 2 as $x | -$x`
was `-1` instead of `-3`. The commit 92daac90f6 (PR #3053) changed
the behavior to emit syntax error on this case. Now, this commit allows
binary operators with `as` binding. This fixes #2446, and fixes #3284.

itchyny de21386681 Fix signed integer overflow in jvp_array_write and jvp_object_rehash 
This commit fixes signed integer overflow and SEGV issues on growing
arrays and objects. The size of arrays and objects is now limited to
`536870912` (`0x20000000`). This fixes CVE-2024-23337 and fixes #3262.

itchyny b733dfaee7 Improve error messages to show problematic position in the filter (#3292) 
This commit improves the parser and compiler error messages, making
it more easier to understand where in the filter the problem is.
Like modern compilers, jq will show the line in the filter where the
error occurred, will display squiggly line under the invalid token.

itchyny 92daac90f6 Fix unary operator precedence, allow some expressions as object values (#3053) 
This commit improves the parser to fix some unintuitive results of the unary
operator `-` (e.g. `[-1 as $x | 1,$x]` is now `[1,-1]`, previously `[-1,-1]`).
Also, this commit now allows to use binary operator expressions, `reduce`,
`foreach`, `if`, and `try` expressions for object values.

Thomas Sibley 931a362f8b docs: Use a better input example in the streaming section (#3322) 
The introduction says all the usage examples (e.g. of truncate_stream,
etc) in the section use [0,[1]] as input, but they actually use [1,[2]].
["a",["b"]] seems better than [1,[2]] as the string values won't be
confusable with the indexes in <path>.

itchyny a8ce2ff09a Avoid zero-length calloc (#3280)

itchyny 4003202ccf Fix segmentation fault on strftime/1 and strflocaltime/1 (#3271) 
When we use a large format string to `strftime/1` and `strflocaltime/1`,
we get segmentation fault. This happens because the result buffer is
allocated on the stack using `alloca` function, and `strftime` function
writes out of the space when the size is not enough to format time.
I fixed the segmentation fault issue by allocating the result buffer on
the heap using `malloc` function, because `alloca` function does not
provide a way to detect insufficient space.

Marcin Serwin 6d8e9f98ae fix: populate timezone data when formatting time (#3203) 
The `jv2tm` function was zeroing fields of `struct tm` that were not
specified by the standard. However, depending on the libc this produced
incorrect timezone data when used together with formatting functions.
This change tries to fill the timezone data using either `mktime`,
`timegm`, or manually.

Apple's Libc implementation contains a bug which causes it to ignore
the offset data present in the `struct tm` in favor of the older heuristic
needed by legacy standards. This workaround temporarily sets the global
timezone so it gets picked up during formatting.

itchyny b86ff49f46 fix: jv_number_value should cache the double value of literal numbers (#3245) 
The code of `jv_number_value` is intended to cache the double value of
literal numbers, but it does not work because it accepts the `jv` struct
by value. This patch fixes the behavior by checking if the double value
is `NaN`, which indicates the unconverted value. This patch improves the
performance of major use cases; e.g. `range(1000000)` runs 25% faster.

Emanuele Torre 8bcdc9304a jq_next: simplify CALL_BUILTIN implementation 2024-12-01 11:49:44 +01:00
Emanuele Torre 0b82b3841b builtin.c: typecheck builtin cfunctions in function_list 
In C23 (default C standard used by GCC 15),  jv (*fptr)();  has become
equivalent to  jv (*fptr)(void);  so we can no longer assign builtin
implemenations directly to the fptr member of cfunctions without
generating a compile error.

Since there does not seem to be any straight-forward way to tell
autoconf to force the compiler to use C99 short of explicitly adding
-std=c99 to CFLAGS, it is probably a cleaner solution to just make the
code C23 compatible.

A possible solution could have been to just redeclare  cfunction.fptr
as void*, but then the functions' return type would not have been type
checked (e.g. if you tried to add a {printf, "printf", 2}, where printf
is a function that does not return jv, the compiler wouldn't have
complained.)
We were already not typechecking the arguments of the functions, so e.g.
  {binop_plus, "_plus", 3},  /* instead of {f_plus, "_plus, 3},       */
  {f_setpath, "setpath", 4}, /* instead of {f_setpath, "setpath", 3}, */
compile without errors despite not having the correct prototype.

So I thought of instead improving the situation by redefining
cfunction.fptr as a union of function pointers with the prototypes that
the jq bytecode interpreter can call, and use a macro to add the builtin
functions to function_list using to the arity argument to assign the
implementation function to the appropriate union member.

Now the code won't compile if the wrong arity, or an arity not supported
by the bytecode interpreter (>5 = 1input+4arguments), or a prototype not
jallable by the bytecode interpreter (e.g. binop_plus that doesn't
expect a  jq_state*  argument).

Also, the code now compiles with gcc -std=c23.

Use `env` to ensure that `NO_COLOR` is set to the desired value
regardless of any initialization that may occur when `script`

Note that `env -u` is not portable, so there is no good solution
for the first test case.

Samar Sunkaria 7be6870751 Remove multiple calls to free when successively calling jq_reset. (#3134) 
`jq_reset` calls `jv_free` on the `exit_code` and the `error_message` stored on the jq state.
However, it doesn't replace the actual instance of those members. This means that subsequent
calls to `jq_reset` will call `jv_free` again on those members, which in turn may call `free`
on the same pointer multiple times. Freeing the same pointer multiple times is undefined
behavior and can cause heap corruption, which is how I spotted this issue.

In practice, this issue only occurs when using a program that may `halt_error`, because that
is when the `exit_code` and `error_message` are set to values other than `jv_invalid`.
Subsequent attempts to call `jq_start` (which calls `jq_reset` internally) after hitting a
`halt_error` can cause you to run into this issue.

The changes simply reset the `exit_code` and the `error_message` to `jv_invalid` (the initial
value set in `jq_init`) after they are freed.

J. B. Rainsberger 4842146e1b Add "make clean" to build instructions 
When I tried to build a new version in the same working directory I'd used to build a previous version, I saw build errors. After a few attempts, I remembered that "make clean" might get past the problem. It seems like a nice thing to suggest to everyone who might fall into the same trap.

Emanuele Torre 5bbd02f581 jv_setpath: fix leak when indexing an array with an array 
arrays[arrays] is a special case of "INDEX" that actually returns an
array containing the indices in which the array that is being indexed
contains the start of the key array.

So array keys, for array values, are a kind of key that can be "got",
but not "set". jv_setpath() was not freeing the value it "got" from
indexing that key, in case the following "set" on that key failed,
resulting in a leak.

    $ ./jq -n '[] | setpath([[1]]; 1)'
    jq: error (at <unknown>): Cannot update field at array index of array

Emanuele Torre d777b6570c util.c: fix _WIN32 port of strptime (#3071) 
In windows, time_t is a signed 32-bit integer type, so TIME_MAX needs to
be declared as INT32_MAX instead of INT64_MAX.

Also bump NetBSD's strptime to revision 1.65 from 1.63 to fix undefined
behaviour (signed integer overflow) bugs.

Related NetBSD problem report:
https://gnats.netbsd.org/cgi-bin/query-pr-single.pl?number=58041

Noticed thanks to a compiler warning in the windows build CI.

I declared the d variable as  time_t  instead of as  unsigned  to ensure
that the signedness/size of  TIME_MAX-d  in the  sse > TIME_MAX-d check
is always correct, and to prevent -Wsign-compare warnings from
triggering in the windows build.

Emanuele Torre 1411ce63d5 strftime/1: fix validation of non-string argument with number input

argument to strftime/1 is a string when the input is a number; this ends
up calling jv_string_value on a non-string value, which does not work,
and causes an assert failure.

Also fix same bug in strflocaltime/1.

Thalia Archibald 3c37522aaa Consistently reset color formatting in jv_dump_term 
Before, arrays would not reset colors after `[` and `,`, but objects
would; it would reset colors twice before `]` and `}`; and some cases of
indentation would have colors applied. Now, colors are reset immediately
after any token that is colored, before any indentation. This makes the
formatting consistent, for the benefit of custom `JQ_COLORS`.

Emanuele Torre 605836b263 builtin.c: fix build with -Woverlength-strings 
C99 only allows string literals long at most 4095 characters.
jq_builtins was a lot longer than that.

I rewrote all the optional libm error stubs in C so the value of
jq_builtins is not build dependent.

I replaced the command that generates builtin.inc with a POSIX compliant
od|sed command that encodes builtin.jq as a comma delimited list of
octal numbers (that can be embedded in C using a {} literal).

I also added -Woverlength-strings to AM_CFLAGS to verify that the
problem is fixed.

Emanuele Torre 1f1e619f4e builtins: make ltrimstr and rtrimstr error for non-string inputs 
Previously, ltrimstr/rtrimstr would just let the input pass through for
non-string inputs or arguments.

That was happening because, they were leaking the errors returned by
startswith/endswith treating them as if they were jv_false().
The leak was resolved by #2977 for 1.7.1

This patch rewrites ltrimstr and rtrimstr in jq, and makes them not
ignore startswith and endswith errors anymore.

Emanuele Torre 71c2ab509a Merge pull request from GHSA-686w-5m7m-54vc 
decNumberToString calls for a buffer that can hold a string of digits+14
characters, not a buffer of size digits+14.
We need to allocate an extra byte for the NUL byte.

-10E-1000010001, for example, will be stringified as -1.0E-1000010000
and decNumberToString will currently write an extra NUL byte after the
allocated buffer in the heap.

This is to make sure fuzzing hits various code parts currently not

Andreas Heiduk 88f01a741c simplify paths/0 and paths/1 
`recurse/0` already handles traversing objects and arrays, so it is more
consistent to use that.
For `paths/1` it is easier to use the actual value returned by
`recurse` instead of querying that value with `getpath/1` afterwards.

Emanuele Torre cca1f7d18f Comment bug fixes, and fully support Tcl-style multiline comments 
* bugfix: comments were incorrectly being terminated by CR; for example
    jq -n $'1 #foo\r'
  fails to compile because the CR character terminates the comment, and
  CR is not a valid character in jq syntax.

* improvement: comments fully support Tcl-style line continuation.
  Previously this was only "supported" in `-f' scripts, whose first line
  starts with "#!", and second line starts with # and ends with \, only
  for the comment on the second line, only for one extra line.

* man: document comment syntax, which was previously undocumented.

* tests: add regression tests for the bugfix, and some tests for line
  continuation in comments.

Klemens Nanni 7ab117a483 Defer heap variable initialisation after pledge 
Otherwise `AGRS` and `program_arguments` remain allocated/unfreed in the
early (extremely unlikely) pledge(2) failure case.

Move their allocation before jq_init(), the first case of jumping to
`out` where they are cleaned up, where it also seems to logically fit
better than above between function entry, locale setup and OpenBSD
specific pledge.

Klemens Nanni f1bfd0c518 Restrict systems operations on OpenBSD 
Use pledge(2)[0] to limit jq(1) to reading files.
It does not change files and only writes to standard output/error.
It never deals with TTY, network, process management or other subsystems.

This is to reduce jq's attack surface and potential damage.

OpenBSD is carrying a local patch[1] in its official jq port/package
since 2016.  An improved version:

- drop no longer needed "getpw" promise
  f1c4947 "Avoid getpwuid for static linking" removed getpwuid(3) usage
- pledge before jq_init() to simplify the error path
- use perror(3) to print errno(2)

No behaviour change in tests or real world usage observed on
OpenBSD/amd64 7.4.

There is no reason to revert this change.

In #2922, I only disagreed with the commit message suggesting that
  LC_CTYPE=C od -t c    is   equivalent to   od -c

The only documented differences are that -tc is required to be
influenced by -N and -j, while -c is not, and that -c is required to
only support a subset of the backslash sequences that -tc should
support.

Emanuele Torre 4ebd21e1eb Allow passing the inline jq script before -- 
jq previously only allowed passing the inline script before -- (as if
they were options) even though one would expect the inline script to be
a positional argument.

Since jq previously also refused to run with a usage error if the script
was passed after -- (It was not assuming  .  as script as it does when
no arguments are passed), and positional arguments are allowed before --
and even before other options, it should not be a breaking change to
change that weird behaviour, and allow the script to appear after --.

It also simplifies the option parsing code a bunch.

Emanuele Torre 8206bc8fd2 main.c: Remove unused EXIT_STATUS_EXACT option 
In process there is a suspicious  options |= EXIT_STATUS_EXACT  that
is run when the jq script is terminated by halt, or halt_error.

That line of code acutally does nothing because options is a local
argument variable, and is not passed as a pointer. It was probably meant
to be a   *options |= EXIT_STATUS_EXACT   with the options argument
passed as a int*.

In any case, we do not want to run the code in main() that was supposed
to run if EXIT_STATUS_EXACT is set (but didn't since it is never added
to options); as far as I can tell, we only want to run that code when
the --exit-status/-e option is passed.

So I removed EXIT_STATUS_EXACT completely, and the useless assignment,
instead of fixing it since it was not used for anything else.

Emanuele Torre ab47880b4c Make jq_get_lib_dirs return an empty array if JQ_LIBRARY_PATH is not set 
For the jq_state used by the jq utility, the JQ_LIBRARY_PATH attribute
will always be set, but, in general, it is possible that it might not
be.

If it is not set, jq_get_lib_dirs() will return jv_invalid().

That is not good, because some code in linker.c expects it to always
returns an array.

This patch makes jq_get_lib_dirs() return an empty array if
JQ_LIBRARY_PATH is not set to prevent problems.

This issue made OSS fuzz trigger failed assertions every time it tried
to compile a script that uses "include".

itchyny 7d64381016 Fix overflow on numeric comparison (#2849) 
Although #2839 fixed the overflow of exponent subtraction,
there still is possibility of overflow in the `D2U` macro.
This patch fixes the overflow in the `D2U` macro, and also
truncates the maximum digits to `DEC_MAX_DIGITS`.

itchyny 3fa10e8cc1 Fix crash on numeric comparison again (ref #2825) 
The decNumber library subtracts the exponents of two numbers,
we make sure to limit the number of digits not to make it overflows.
Since the maximum adjusted exponent is `emax` and the minimum is
`emin - digits + 1`, we follow `emax - (emin - digits + 1) <= INT32_MAX`.

Emanuele Torre f94a9d463f Let error(null) throw null 
This patch removes the weird behaviour of jv_invalid_with_msg(jv_null())
that returns jv_invalid() (i.e. empty), instead of a boxed jv_null().

The previous behaviour of  null|error  was obviously unintentional, and
allowing is jv_invalid_with_msg() to return values on which you can't
call jv_invalid_get_msg() is only error prone.

Emanuele Torre 3b6e7ddd72 Constant fold all kinds of constants 
This patch exports all the binary operator builtins functions from
builtin.c and uses them for constant folding in the parser, allowing
constant folding to work will all kinds and combinations of constants.

Now string*number,  $ARGS+$ARGS,  string/string,  etc will also be
constant folded and the implementation of constant folded operators and
runtime operators will be the same.

And thanks to the new ERRORK bytecode operation, errors are constant
folded too! (e.g. 1 / 0   [] * {}   etc)

Use a StringStart component that is either FORMAT QQSTRING_START or

This is simpler and avoids having to use an untyped mid-rule action
component to copy FORMAT at the top of the stack before QQString, and
having to use jv_free($<literal>3) instead of jv_free($1) just to make
bison not complain about the "unused" mid-rule component.

itchyny 0f80921268 Fix constant folding of division and reminder with zero divisor 
Previously constant folding of zero division (e.x. 1/0) produces a
compile error. This was incorrectly implemented by checking if the
division result is infinite, so produces wrong results compared to the
query where no constant folding is processed (e.x. 1e308/0.1). This
patch delays the operation when the divisor is zero. This makes the
results more consistent, but changes the exit code on zero division from
3 to 5. Also 0/0 now produces the zero division error, not NaN.

This patch also fixes the modulo operation. Previously constant folding
logic does not take care of the % operator, but now it folds if the both
dividend and divisor are safe numbers to cast to the integer type, and
the divisor is not zero. This patch also fixes some code that relies on
undefined cast behaviors in C. The modulo operation produces NaN if
either the dividend or divisor is NaN.

Emanuele Torre 6716e23ae6 Declare cfunction.fptr as jv (*)() to avoid having to cast everywhere 
You only need to specify the return type in a function pointer
declaration in C.

If you use () in the declaration, the function pointer can be called
with any arguments, and the type of the arguments is decided for each
function call based on the types of the arguments used for the call.
(To declare a function pointer for a function with no arguments, you use
`(void)'.)

Since all the cfunction structs have a  fptr  that points to a functions
that return jv, not void, we can we can just declare cfunction.fptr as
jv (*)()  and avoid having those annoying and technically not C-standard
compliant casts everywhere.

itchyny a1e791acf8 Rename --nul-output to --raw-output0, abort on string containing NUL 
The option naming --nul-output was confusing, especially when we have a
similar option for input stream in the future (--nul-input vs --null-input).
Based on the observation of other command line tools, we rename the option
to --raw-output0. We also drop the short option -0 to avoid confusion on
introducing the NUL-delimited input option.

Unlike the other command line tools outputting file names with NUL delimiter,
jq deals with JSON, and its strings may contain NUL character. To protect
users from the risk of injection attacks, we abort the program and print an
error message before outputting strings including NUL character. Closes #2683.

Emanuele Torre ae95864b6b Make sure to free default @text format on error 
It seems that bison doesn't call destructors for mid-rule action
components on error, since it does not know their type.

A mid-rule action was used to allocate the "text" string used as format
by string literals without a format, which would leak on error.
This patch replaces it with a new NoFormat component of type <literal>.
Now bison will call jv_free() on that string after a syntax error.

Fixes https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=60836

Close #1885, #2140, #2011, #2220, #2485, #2073

Rename the FORK_OPT opcode to TRY_BEGIN, add a TRY_END opcode, and wrap
errors when raising through a TRY_END so that they will not be caught by
the matching TRY_BEGIN.

Now a `try exp catch handler` expression generates code like:

    TRY_BEGIN handler
    <exp>
    TRY_END
    JUMP past_handler
    handler: <handler>
    past_handler:
    ...

On backtrack through TRY_BEGIN it just backtracks.

If anything past the whole thing raises when <exp> produced a value,
then the TRY_END will catch the error, wrap it in another, and
backtrack.  The TRY_BEGIN will see a wrapped error and then it will
unwrap and re-raise the error.

If <exp> raises, then TRY_BEGIN will catch the error and jump to the
handler, but the TRY_BEGIN will not stack_save() in that case, so on
raise/backtrack the TRY_BEGIN will not execute again (nor will the
TRY_END).

If we don't populate, captures for empty matches, the replacement
expression is run with an empty object as input instead of an object
containing the named captures with "" as value:

* before:

  $ jq -n '"123foo456bar" | gsub("[^a-z]*(?<x>[a-z]*)"; "Z\(.x)")'
  "ZfooZbarZnull"

* after:

  $ jq -n '"123foo456bar" | gsub("[^a-z]*(?<x>[a-z]*)"; "Z\(.x)")'

To avoid causing segmentation faults when  input/1  is called in a

used by  jq --run-tests.

That segfault could also be fixed in run_jq_tests() by calling:

  jq_set_input_cb(jq, NULL, NULL);

But I think it makes sense to just make jq_init() initialise those
values to NULL.

Using { $x: "foo" } where $x is not a string is an error, so there is
not much of a point in supporting that.

Emanuele Torre 193f432e08 Lex $foo as a single token, instead of using '$' IDENT 
Previously, bindings were parsed as the combination of two tokens:
  '$' IDENT

This meant that using a keyword as variable name (e.g. $then, $label)
did not work.
Attempts were made to allow $keyword to work by adding some '$' Keyword
rules in the parser, but this did not allow $keyword in all places:

  jq --arg label foo -n '$label'  # ok

  jq -n '"foo" as $label | .'     # error

Treating $foo as a single token is much simpler, in my opinion.

This patch also changes how LOC is lexed: "$__loc__" instead of as
"__loc__" that gets combined with '$' in the parser.

This patch also disallows having spaces after '$' when recalling a
variable  `$ foo'  since that was probably just an unintentional side
effect of the implementation, and it was not documented.

pkoppstein 83f375cc83 Revamp sub/3 to resolve most issues with gsub (and sub with "g") (#2641) 
The primary purpose of this commit is to rectify most problems with
`gsub` (and also `sub` with the `g` option), in particular fix #1425 ('\b'),
fix #2354 (lookahead), and fix #2532 (regex == `"^(?!cd ).*$|^cd "`).

This commit also partly resolves #2148 and resolves #1206 in that
`gsub` no longer loops infinitely; however, because the new `gsub`
depends critically on `match/2`, the behavior when regex == `""` is
sometimes non-standard.

The documentation has been updated to reflect the fact that `sub`
and `gsub` are intended to be regular in the second argument.

Also, `_nwise/1` has been tweaked to take advantage of TCO.

* Only enable CI when push to master & tag

* Try out statick build

* No need to enforce the same `AM_INIT_AUTOMAKE` version for MacOS

* Disable static build for ubuntu-20.04

Florian Weimer 52d5988afb C99 compatibility enhancements for the configure script (#2519) 
* configure.ac: Enable system extensions

Use AC_USE_SYSTEM_EXTENSIONS to build with _GNU_SOURCE (and similar
macros on non-GNU systems), to avoid an implicit declaration of the
strptime function.  This improves compatibility with future compilers
which do not support implicit function declarations.

* configure.ac: gettimeofday lives in <sys/time.h>

The gettimeofday function is declared in <sys/time.h>, not <time.h>,
according to POSIX and actual systems.  This avoids a configure
probe failure with compilers which do not support implicit function
declarations.

MacOS build [fails](https://github.com/jqlang/jq/actions/runs/5114162555/jobs/9194126677#step:6:3160) due to

```

  onig_end();
```

The current `oniguruma` revision
6fa38f4084b448592888ed9ee43c6e90a46b5f5c (15 Mar 2017) lacks the following explicit declaration in src/onigposix.h:

```

Nicolas Williams a9f97e9e61 Fix accidentally quadratic behavior in _modify 
We need to be careful to not grab an extra reference when mutating data
structures because that means we make extra copies.  Doing that every
time in `_modify` is really painful, as that function implements `|=`
and all modify-assign operators.

`jv_setpath()` also grabs additional references, so this is not the only
fix needed for the modify-assign operators to not be accidentally
quadratic.

We have to use `LOADVN` in order to make this fix possible, so we should
really byte-code `_modify` rather than jq-code it.  However, as a
stop-gap to make this fix easier, I'm adding syntax for referring to a
`$binding` such that you get `LOADVN` instead of `LOADV`.

This syntax is not meant to be used outside jq's internals!  Therefore
it is not documented.  I promise to break it later, so don't use it!

TBD, but later:

 - Optimize `_modify` for the case where `update` outputs more than one
   value.

   This is trivial: add a `setpath($p; null)` in the middle of `_modify`
   before calling `update`.  But unfortunately the VM retains a
   reference to `value_at_path` for path expression checking, and fixing
   that will require more work.

Nicolas Williams 0c3455d329 Fix accidentally quadratic behavior in setpath 
We need to be careful to not grab an extra reference when mutating
data structures because that means we make extra copies.  Doing that
every time in `jv_setpath()` is really painful, as that function is used
in `_modify/2`, which is used in `|=` and all modify-assign operators.

`_modify` also grabs additional references, so this is not the only fix
needed for the modify-assign operators to not be accidentally quadratic.

Nicolas Williams 582717a7b4 Fix crash in LOADVN when stack grows 
This `stack_push()` call in LOADVN invalidates `var`:

       jv* var = frame_local_var(jq, v, level);
       jv_free(stack_popn(jq));
------>stack_push(jq, *var);
       *var = jv_null();
       ^^^^^^

We have to re-compute `var`:

       jv* var = frame_local_var(jq, v, level);
       jv_free(stack_popn(jq));
       stack_push(jq, *var);
------>var = frame_local_var(jq, v, level);
       *var = jv_null();

[
       1
]
$ jq --indent 8 -n '[1]'
jq: --indent takes a number between -1 and 7
Use jq --help for help with command-line options,
or see the jq manpage, or online docs  at https://stedolan.github.io/jq

This patch was generated by running `git grep "no more than"` and fixing

Leonid S. Usov cf4b48c7ba Save literal value of the parsed number to preserve it for the output 
Extend jv_number to use decNumber for storing number literals. Any math
operations on the numbers will truncate them to double precision.
Comparisons when both numbers are literal numbers will compare them
without truncation.

Delay conversion of numbers to doubles until a math operation is performed,
to preserve precision. A literal jv_number will only need conversion to
double once, and will reuse the resultant double on subsequent
conversions.

Outputting literal jv_numbers preserves the original precision.

Add strong pthread requirement to manage contexts/allocations for
converting numbers between their decNumber, string, and double formats.

docs: fix seriously dangerous download instructions for Arch Linux
 2019-07-31 12:20:51 -04:00
Eli Schwartz 78774647e1 docs: fix seriously dangerous download instructions for Arch Linux 
The current instructions tell users to perform two actions:
- update the package database
- install the jq package

The only thing users need to or should be doing is actually installing
the jq package -- regardless of which version is being installed.
Guidelines on how to perform system updates are massively out of scope.

In the case of partially performing a system update as a prerequisite
for installing jq, the official guidance from Arch Linux is not to do
this: partial updates are not supported, we refuse to support them, and
anyone who does try to perform them anyway is assumed to know so much
about their system that they clearly do not ever need help from anyone
else (which is a good thing since they won't get it). The result is a
frankensteined system that can only ever be supported by the person who
frankensteined it to begin with. The only reason the package manager
even allows it to occur in the first place is because other
distributions using pacman might have different LTS policies, and
because it would prevent expert users from being in control of their
system, as per the traditional Unix philosophy:

"Unix was not designed to stop you from doing stupid things, because
that would also stop you from doing clever things."

Consequences of performing partial updates without understanding the
ramifications in extensive detail can include breaking the partially
updated application (jq), breaking any application that shares a mutual
dependency with the partially updated application (which jq is *lucky*
to only depend on the ever-backwards-compatible glibc), or breaking the
entire operating system by leaving armed traps behind for the next time
a `pacman -S new-package` is executed and thereby breaks *its* cascading
dependencies.

The current paragraph is not complete, since a digit is not a special character.

Changing it to:

    If the key contains special characters or starts with a digit,
    you need to surround it with double quotes like this:
    `."foo$"`, or else `.["foo$"]`.

Nicolas Williams b52fc1043b Fix assert in generator subexpressions (fix #1875) 
Expressions of the form `path(EXPR) | select(GENERATOR)`, where `EXPR`
is a path expression and `GENERATOR` is a generator conditional
expression (e.g., `has("a"), has("b")`) cause an assertion if the
jq_state VM is torn down too soon.  That assert() was only correct if
assuming that the conditional is not a generator.

If the conditional is generator, then what we see is that when
backtracking a SUBEXP_END is executed without a corresponding
SUBEXP_BEGIN because the entire conditional is bracketed with
SUBEXP_BEGIN and SUBEXP_END, and since it's resumed in the middle, in
between the brackets.

Rather than assert that the jq->path_len being restored has some
particular value, we can simply re-compute it from the restored
jq->path.

block_bind_incremental is block_bind_referenced in a loop backwards. For

expensive, so it's not really useful to keep both.

Also, block_bind_referenced was a better name for the function.

Muh Muhten 8537b93a43 Fix block flipping in block_drop_unreferenced 
Since 605bfb3, block_drop_unreferenced actually reverses the order of

fact that normally it's run *twice* against the main program, flipping
it back, and that order of function definitionss doesn't really matter
after symbol resolution.

This is possibly more expensive, but at least it should be correct.

Muh Muhten e843a4fdf9 Make builtin binding fast again by binding only referenced symbols 
Avoid doing the internal binding of top-level symbols in the parser,
leaving that work to be done in a post-processing step. For builtins,
this lets us do a reference-aware bind step (block_bind_incremental)
*after* generating builtins/0.

Libraries are a bit trickier since they may be bound multiple times, so
instead of thinking through the implications I added (block_bind_self)
to resolve all internal symbols immediately.

would be better to error out here, but at least one similar loop already
uses < vs != and since we're off the rails anyway this might be OK.  It is
certainly better than overruning the buffer.

my_timegm was introduced in 1900c7 to add a mktime fallback used in
4a6241, the subsequently removed in c53823. As a result of this code
shuffling, the jq mktime function (f_mktime) wound up using a fallback
even on systems where timegm is available, with incorrect results in
some time zones with DST, e.g.

% TZ=America/New_York jq -n '"2018-08-31T00:00:00Z"|fromdate|todate'
"2018-08-31T01:00:00Z"

Nicolas Williams 8ea4a5584e Allow variable refs as object keys {$key:value} 
Users are often surprised by the requirement to parenthesize any
non-trivial object key expressions in object constructors.  E.g.,
{"a"+"b":1}.  This commit adds one more kind of key expression besides
literals and idents: variable references.

A common use case for this is jq programs as JSON templates to fill in
with variables computed from inputs or passed in on the command-line.
E.g., {some_key:$value}.  Now users can also use, e.g., {$key:$value}.

This and the restrictions on key and value expressions in object
constructors are now clarified a bit in the documentation.

Alex Ozdemir 0c845aa291 Bugfix: Math function checking 
We had config machinery that determined which math functions are
available in libc. If a c math function was missing on the host system,
then the corresponding jq function would be removed from the source,
enabling the build to proceed anyway. The detection machinery was broken
in a subtle way, as was shown after glibc updated to 2.27, dropping the
`pow10` function. This caused compilation to fail.

The essential problem was that we detected whether a math function was
available by compiling and linking a small program evaluating that
function on constants. However, since gcc's optimization machinery has
special knowledge of some math functions (e.g. `pow10`), it can
optimize them away, even if they don't exist in the library and are not
linkable. That is, the following example compiles and links against
glibc 2.27, even though `pow10` has been removed:
```
int main () {
  printf("%f", pow10(0.5));
  return 0;
}
```

What?!
On the other hand, this program does not link:
```

int main () {
  double f;
  printf("%f", &f);
  printf("%f", pow10(f));
  return 0;
}
```

In the first program the call to `pow10` can be optimized away as a
constant expression. This requires GCC to know about `pow10` (which it
does!), but it does not require `pow10` to be in the library (and
actually linkable).

The solution is to use autoconf's machinery for detecting function
presence, instead of our own (buggy) machinery. This has the added
benefit of simplifying the code.

The bug was reported in issue #1659

William Langford 0673dee1b3 Fix destructuring alternation 
Attempting to use the existing FORK_OPT opcode resulted in difficulty
knowing when to pop an error message off the stack and when not to. This
commit makes DESTRUCTURE_ALT a real opcode that is identical to
FORK_OPT, except for never pushing the error message onto the stack when
continuing from an error backtrack.

Some small changes were necessary to the DUP/POP behavior surrounding
destructuring to accomodate this.

Nicolas Williams 9a4576e756 Revert "reduce: handle empty updates (fix #1313)" 
This reverts commit e24af3c78e.

While the semantics are desirable, there is no way to implement them
efficiently.  The reason is that in order to handle backtracking (empty)
from the state update expression, we have to retain a reference to the
reduction state value in order to restore it upon backtracking.
Retaining a reference to the reduction state kills performance by
causing lots of additional memory allocations and garbage because the
input to the update expression will always have at least two references,
thus no changes to it can be done in-place, and all changes end up being
CoW changes.

Avoiding this is the very reason for the LOADVN instruction (leaving
`null` in the variable loaded from).

This has been a complicated issue to fix for a number of reasons.
The core of it is that the behavior is different between different
versions of macOS, some of which set possible-but-incorrect values.

This commit addresses the issue by always using our computation for
tm_wday and tm_yday on macOS. As a side-effect, strptime format
strings that specify %u and %j will no longer work on macOS.

Nicolas Williams c538237f4e Deal with strptime() on OS X and *BSD (fix #1415) 
strptime() on OS X and *BSDs (reputedly) does not set tm_wday and
tm_yday unless corresponding %U and %j format specifiers were used.
That can be... surprising when one parsed year, month, and day anyways.
Glibc's strptime() conveniently sets tm_wday and tm_yday in those cases,
but OS X's does not, ignoring them completely.

This commit makes jq compute those where possible, though the day of
week computation may be wrong for dates before 1900-03-01 or after
2099-12-31.

Nicolas Williams bd7b48c1b9 Make |= delete LHS when RHS is empty (Fix #1314) 
Now that #1313 is fixed, |= no longer outputs null when the RHS update
expression outputs empty.

When a user wants to keep the current value of the LHS they would have
the RHS update expression output `.`, so having `empty` achieve the same
thing would be redundant.  The obvious thing to do is to delete the LHS
when the RHS update outputs `empty` (i.e., doesn't output any values).

It's reasonable to think that existing programs won't be broken by this
change, because reduce and |= not handling empty well is clearly a bug.
(Though it's possible that some programs were using empty to quickly
terminate reduce or |=, it's not likely.  They should use label/break
instead.)

Prior to this change |= would use the _last_ value output by the RHS
update expression.  With this change |= will use the _first_ value
instead.  This change _is_ a minor backwards-incompatible change.  It
may or may not be acceptable; we'll see.  It is a useful change in that
it makes |= faster when the update expression produces multiple values.

New features in 1.5 since 1.4:
- regular expressions (with Oniguruma)
- a library/module system
- many new builtins
- datetime builtins
- math builtins
- regexp-related builtins
- stream-related builtins (e.g., all/1, any/1)
- minimal I/O builtins (`inputs`, `debug`)
- new syntactic features, including:
- destructuring (`. as [$first, $second] | ...`)
- try/catch, generalized `?` operator, and label/break
- `foreach`
- multiple definitions of a function with different numbers of
arguments
- command-line arguments
- --join-lines / -j for raw output
- --argjson and --slurpfile
- --tab and --indent
- --stream (streaming JSON parser)

New features in 1.4 since 1.3:
- command-line arguments
- jq --arg-file variable file
- jq --unbuffered
- jq -e / --exit-status (set exit status based on outputs)
- jq -S / --sort-keys (now jq no longer sorts object keys by
default
- syntax
- .. -> like // in XPath (recursive traversal)
- question mark (e.g., .a?) to suppress errors
- ."foo" syntax (equivalent to .["foo"])
- better error handling for .foo
- added % operator (modulo)
- allow negation without requiring extra parenthesis

- explode, implode
- fromjson, tojson
- index, rindex, indices
- math functions
- floor, sqrt, cbrt, etetera (depends on what's available from libm)
- libjq -- a C API interface to jq's JSON representation and for
running jq programs from C applications

"hello"
"hello "
" hello"
```
- Add `trimstr/1` to trim string from both ends. @gbrlmarn #3319
```sh
$ jq -n '"foobarfoo" | trimstr("foo")'
"bar"
```
- Add `add/1`. Generator variant of `add/0`. @myaaaaaaaaa #3144
```sh
$ jq -c '.sum = add(.xs[])' <<< '{"xs":[1,2,3]}'
{"xs":[1,2,3],"sum":6}
```

- Remove private (and undocumented) `_nwise` filter. @itchyny #3260
## Language changes
- Fix precedence of binding syntax against unary and binary operators.
Also, allow some expressions as object values. @itchyny #3053 #3326
- This is a breaking change that may change the output of filters with binding syntax as follows.
```sh
$ jq -nc '[-1 as $x | 1,$x]'
[1,-1] # previously, [-1,-1]
$ jq -nc '1 | . + 2 as $x | -$x'
-3 # previously, -1
$ jq -nc '{x: 1 + 2, y: false or true, z: null // 3}'
{"x":3,"y":true,"z":3} # previously, syntax error
```
- Support Tcl-style multiline comments. @emanuele6 #2989
```sh
#!/bin/sh --
# Can be use to do shebang scripts.
# Next line will be seen as a comment be of the trailing backslash. \
exec jq ...
# this jq expression will result in [1]
[
1,
# \
2
]
```
- Fix `foreach` not to break init backtracking with `DUPN`. @kanwren #3266
```sh
$ jq -n '[1, 2] | foreach .[] as $x (0, 1; . + $x)'
1
3
2
4
```
- Fix `reduce`/`foreach` state variable should not be reset each iteration. @itchyny #3205
```sh
$ jq -n 'reduce range(5) as $x (0; .+$x | select($x!=2))'
8
$ jq -nc '[foreach range(5) as $x (0; .+$x | select($x!=2); [$x,.])]'
[[0,0],[1,1],[3,4],[4,8]]
```
- Support CRLF line breaks in filters. @itchyny #3274

- OSS-fuzz. @DavidKorczynski #2760 #2762
Full commit log can be found at <https://github.com/jqlang/jq/compare/jq-1.6...jq-1.7> but here are some highlights:
## CLI changes
- Make object key color configurable using `JQ_COLORS` environment variable. @itchyny @haguenau @ericpruitt #2703
```sh
# this would make "field" bold yellow (`1;33`, the last value)
$ JQ_COLORS="0;90:0;37:0;37:0;37:0;32:1;37:1;37:1;33" ./jq -n '{field: 123}'
{
"field": 123
}
```
- Change the default color of null to Bright Black. @itchyny #2824
- Respect `NO_COLOR` environment variable to disable color output. See <https://no-color.org> for details. @itchyny #2728
- Improved `--help` output. Now mentions all options and nicer order. @itchyny @wader #2747 #2766 #2799
- Fix multiple issues of exit code using `--exit-code`/`-e` option. @ryo1kato #1697
```sh
# true-ish last output value exits with zero
$ jq -ne true ; echo $?
true
0
# false-ish last output value (false and null) exits with 1
$ jq -ne false ; echo $?
false
1
# no output value exists with 4
$ jq -ne empty ; echo $?
4
```
- Add `--binary`/`-b` on Windows for binary output. To get `\n` instead of `\r\n` line endings. @nicowilliams 0dab2b1
- Add `--raw-output0` for NUL (zero byte) separated output. @asottile @pabs3 @itchyny #1990 #2235 #2684
```sh
# will output a zero byte after each output
$ jq -n --raw-output0 '1,2,3' | xxd
00000000: 3100 3200 3300 1.2.3.
# can be used with xargs -0
$ jq -n --raw-output0 '"a","b","c"' | xargs -0 -n1
a
b
c
$ jq -n --raw-output0 '"a b c", "d\ne\nf"' | xargs -0 printf '[%s]\n'
[a b c]
[d
e
f]
# can be used with read -d ''
$ while IFS= read -r -d '' json; do
> jq '.name' <<< "$json"
> done < <(jq -n --raw-output0 '{name:"a b c"},{name:"d\ne\nf"}')
"a b c"
"d\ne\nf"
# also it's an error to output a string containing a NUL when using NUL separator
$ jq -n --raw-output0 '"\u0000"'
jq: error (at <unknown>): Cannot dump a string containing NUL with --raw-output0 option
```
- Fix assert crash and validate JSON for `--jsonarg`. @wader #2658
- Remove deprecated `--argfile` option. @itchyny #2768
- Enable stack protection. @nicowilliams #2801
## Language changes
- Use decimal number literals to preserve precision. Comparison operations respects precision but arithmetic operations might truncate. @leonid-s-usov #1752
```sh
# precision is preserved
$ echo '100000000000000000' | jq .
100000000000000000
# comparison respects precision (this is false in JavaScript)
$ jq -n '100000000000000000 < 100000000000000001'
true
# sort/0 works
$ jq -n -c '[100000000000000001, 100000000000000003, 100000000000000004, 100000000000000002] | sort'
[100000000000000001,100000000000000002,100000000000000003,100000000000000004]
# arithmetic operations might truncate (same as JavaScript)
$ jq -n '100000000000000000 + 10'
100000000000000020
```
- Adds new builtin `pick(stream)` to emit a projection of the input object or array. @pkoppstein #2656 #2779
```sh
$ jq -n '{"a": 1, "b": {"c": 2, "d": 3}, "e": 4} | pick(.a, .b.c, .x)'
{
"a": 1,
"b": {
"c": 2
},
"x": null
}
```
- Adds new builtin `debug(msgs)` that works like `debug` but applies a filter on the input before writing to stderr. @pkoppstein #2710
```sh
$ jq -n '1 as $x | 2 | debug("Entering function foo with $x == \($x)", .) | (.+1)'
["DEBUG:","Entering function foo with $x == 1"]
["DEBUG:",2]
3
$ jq -n '{a: 1, b: 2, c: 3} | debug({a, b, sum: (.a+.b)})'
["DEBUG:",{"a":1,"b":2,"sum":3}]
{
"a": 1,
"b": 2,
"c": 3
}
```
- Adds new builtin `scan($re; $flags)`. Was documented but not implemented. @itchyny #1961
```sh
# look for pattern "ab" in "abAB" ignoring casing
$ jq -n '"abAB" | scan("ab"; "i")'
"ab"
"AB"
```
- Adds new builtin `abs` to get absolute value. This potentially allows the literal value of numbers to be preserved as `length` and `fabs` convert to float. @pkoppstein #2767
- Allow `if` without `else`-branch. When skipped the `else`-branch will be `.` (identity). @chancez @wader #1825 #2481
```sh
# convert 1 to "one" otherwise keep as is
$ jq -n '1,2 | if . == 1 then "one" end'
"one"
2
# behaves the same as
$ jq -n '1,2 | if . == 1 then "one" else . end'
"one"
2
# also works with elif
$ jq -n '1,2,3 | if . == 1 then "one" elif . == 2 then "two" end
"one"
"two"
3
```
- Allow use of `$binding` as key in object literals. @nicowilliams 8ea4a55

# jq
jq is a lightweight and flexible command-line JSON processor.
`jq` is a lightweight and flexible command-line JSON processor akin to `sed`,`awk`,`grep`, and friends for JSON data. It's written in portable C and has zero runtime dependencies, allowing you to easily slice, filter, map, and transform structured data.
[![Coverage Status](https://coveralls.io/repos/stedolan/jq/badge.svg?branch=master&service=github)](https://coveralls.io/github/stedolan/jq?branch=master),
Unix: [![Build Status](https://travis-ci.org/stedolan/jq.svg?branch=master)](https://travis-ci.org/stedolan/jq),
Windows: [![Windows build status](https://ci.appveyor.com/api/projects/status/mi816811c9e9mx29?svg=true)](https://ci.appveyor.com/project/stedolan/jq)
## Documentation
- **Official Documentation**: [jqlang.org](https://jqlang.org)
- **Try jq Online**: [play.jqlang.org](https://play.jqlang.org)
If you want to learn to use jq, read the documentation at
[https://stedolan.github.io/jq](https://stedolan.github.io/jq). This
documentation is generated from the docs/ folder of this repository.
You can also try it online at [jqplay.org](https://jqplay.org).
## Installation
If you want to hack on jq, feel free, but be warned that its internals
are not well-documented at the moment. Bring a hard hat and a
shovel. Also, read the wiki: https://github.com/stedolan/jq/wiki
### Prebuilt Binaries
Source tarball and built executable releases can be found on the
homepage and on the github release page, https://github.com/stedolan/jq/releases
Download the latest releases from the [GitHub release page](https://github.com/jqlang/jq/releases).
The platform-specific assets are standalone executables, not archives. On macOS and Linux,
rename the downloaded file to `jq` and make it executable with `chmod +x jq`.
If you're building directly from the latest git, you'll need flex,
bison (3.0 or newer), libtool, make, and autoconf installed. To get
regexp support you'll also need to install Oniguruma (note that jq's
tests require regexp support to pass). To build, run:
### Docker Image
autoreconf -i # if building from git
./configure
make -j8
make check
Pull the [jq image](https://github.com/jqlang/jq/pkgs/container/jq) to start quickly with Docker.
To build without bison or flex, add `--disable-maintainer-mode` to the
./configure invocation:
#### Run with Docker
./configure --disable-maintainer-mode
##### Example: Extracting the version from a `package.json` file
(Developers must not use `--disable-maintainer-mode`, not when making
changes to the jq parser and/or lexer.)
```bash
docker run --rm -i ghcr.io/jqlang/jq:latest < package.json '.version'
```
To build a statically linked version of jq, run:
##### Example: Extracting the version from a `package.json` file with a mounted volume
make LDFLAGS=-all-static
```bash
docker run --rm -i -v "$PWD:$PWD" -w "$PWD" ghcr.io/jqlang/jq:latest '.version' package.json
```
After make finishes, you'll be able to use `./jq`. You can also
install it using:
### Building from source
sudo make install
#### Dependencies
If you're not using the latest git version but instead building a
released tarball (available on the website), then you won't need to
run `autoreconf` (and shouldn't), and you won't need flex or bison.
- libtool
- make
- automake
- autoconf
To cross-compile for OS X and Windows, see docs/Rakefile's build task
and scripts/crosscompile. You'll need a cross-compilation environment,
such as Mingw for cross-compiling for Windows.
#### Instructions
Cross-compilation requires a clean workspace, then:
```console
git submodule update --init # if building from git to get oniguruma
autoreconf -i # if building from git
./configure --with-oniguruma=builtin
make clean # if upgrading from a version previously built from source
make -j8
make check
sudo make install
sudo ldconfig # on Linux, if jq cannot find libjq.so
```
# git clean ...
autoreconf -i
./configure
make distclean
scripts/crosscompile <name-of-build> <configure-options>
Build a statically linked version:
Use the --host= and --target= ./configure options to select a
cross-compilation environment. See also the wiki.
```console
make clean
make LDFLAGS=-all-static
```
Send questions to https://stackoverflow.com/questions/tagged/jq or to the #jq channel (http://irc.lc/freenode/%23jq/) on Freenode (https://webchat.freenode.net/).
If you're not using the latest git version but instead building a released tarball (available on the release page), skip the `autoreconf` step, and flex or bison won't be needed.
##### Cross-Compilation
For details on cross-compilation, check out the [GitHub Actions file](.github/workflows/ci.yml) and the [cross-compilation wiki page](https://github.com/jqlang/jq/wiki/Cross-compilation).

# How to report security vulnerabilities in `jq`
GitHub has a [mechanism for private disclosure of vulnerabilities](https://docs.github.com/en/code-security/security-advisories/guidance-on-reporting-and-writing/privately-reporting-a-security-vulnerability) to repository owners and authorized persons such as maintainers. The `jqlang/jq` repository now has this feature enabled.
## Reporting a Vulnerability
See [Privately Reporting a Security Vulnerability](https://docs.github.com/en/code-security/security-advisories/guidance-on-reporting-and-writing/privately-reporting-a-security-vulnerability). Click on [`jqlang/jq`](https://github.com/jqlang/jq)'s [Security page](https://github.com/jqlang/jq/security) and click on [Report a vulnerability](https://github.com/jqlang/jq/security/advisories/new). This will notify the owners and maintainers. After submitting you'll get an option to start a private clone of `jqlang/jq` for collaboration with the maintainers.

=============
The jq website, manpages and some of the tests are generated from this
directory. The directory holds a [Bonsai](http://tinytree.info)
website, and the manual is a YAML file in `content/3.manual`.
directory. The manual is a YAML file in `content/manual`.
To build the documentation (including building the jq manpage), you'll
need a working Ruby setup. The easiest way to get one is to install
RVM and Ruby 1.9.3 like so:
need `python3` and `pipenv`. You can install `pipenv` like so:
\curl -L https://get.rvm.io | bash -s stable --ruby=1.9.3
pip install pipenv
After that finishes installing, you'll need to make sure RVM is on
your path by doing `source $HOME/.rvm/scripts/rvm`, or just opening a
new shell. See <https://rvm.io> for more info on RVM.
Though, you may need to say `pip3` instead, depending on your system. Once
you have `pipenv` installed, you can install the dependencies by running
`pipenv sync` from the `docs/` directory.
Once RVM is installed, you can install all the dependencies for jq's
documentation build by running this from the `docs` directory:
Also, you may need to run `virtualenv -p /usr/bin/python3 venv/` and
then `source venv/bin/activate`, and only then `pipenv sync`.
bundle install
Once this is done, rerun `./configure --enable-docs` in the jq root directory and then
the `Makefile` will be able to generate the jq manpage. You can just run
`make jq.1` to build the manpage manually, and `make tests/man.test` to
update the manual tests.
When bundle manages to install the dependencies, rerun `./configure`
in the jq root directory and then the Makefile will be able to
generate the jq manpage.
To build the website, run `pipenv run python3 build_website.py` in the `docs/` directory.
To serve them locally, you can run `python3 -m http.server -d output`.

GitHub returns nicely formatted JSON. For servers that don't, it can be
helpful to pipe the response through jq to pretty-print it. The simplest
jq program is the expression `.`, which takes the input and produces it
unchanged as output.

For the rest of the examples, I'll leave out the `curl` command - it's not
going to change.
There's a lot of info we don't care about there, so we'll restrict it down
to the most interesting fields.
- command: "jq '.[0] | {message: .commit.message, name: .commit.committer.name}'"
result: |
{
"message": "Merge pull request #162 from stedolan/utf8-fixes\n\nUtf8 fixes. Closes #161",
"name": "Stephen Dolan"
}
- text: |
The `|` operator in jq feeds the output of one filter (`.[0]` which gets
the first element of the array in the response) into the input of another
(`{...}` which builds an object out of those fields). You can access
nested attributes, such as `.commit.message`.
Now let's get the rest of the commits.
- command: "jq '.[] | {message: .commit.message, name: .commit.committer.name}'"
result: |
{
"message": "Merge pull request #162 from stedolan/utf8-fixes\n\nUtf8 fixes. Closes #161",
"name": "Stephen Dolan"
}
{
"message": "Reject all overlong UTF8 sequences.",
"name": "Stephen Dolan"
}
{
"message": "Fix various UTF8 parsing bugs.\n\nIn particular, parse bad UTF8 by replacing the broken bits with U+FFFD\nand resychronise correctly after broken sequences.",
"name": "Stephen Dolan"
}
{
"message": "Fix example in manual for `floor`. See #155.",
"name": "Stephen Dolan"
}
{
"message": "Document floor",
"name": "Nicolas Williams"
}
- text: |
`.[]` returns each element of the array returned in the response, one at a
time, which are all fed into
`{message: .commit.message, name: .commit.committer.name}`.
Data in jq is represented as streams of JSON values - every jq
expression runs for each value in its input stream, and can
produce any number of values to its output stream.
Streams are serialised by just separating JSON values with
whitespace. This is a `cat`-friendly format - you can just join
two JSON streams together and get a valid JSON stream.
If you want to get the output as a single array, you can tell jq to
"collect" all of the answers by wrapping the filter in square
brackets:
- command: "jq '[.[] | {message: .commit.message, name: .commit.committer.name}]'"
result: |
[
{
"message": "Merge pull request #163 from stedolan/utf8-fixes\n\nUtf8 fixes. Closes #161",
"name": "Stephen Dolan"
},
{
"message": "Reject all overlong UTF8 sequences.",
"name": "Stephen Dolan"
},
{
"message": "Fix various UTF8 parsing bugs.\n\nIn particular, parse bad UTF8 by replacing the broken bits with U+FFFD\nand resychronise correctly after broken sequences.",

Next, let's try getting the URLs of the parent commits out of the
API results as well. In each commit, the GitHub API includes information
about "parent" commits. There can be one or many.
"parents": [
{
"sha": "54b9c9bdb225af5d886466d72f47eafc51acb4f7",
"url": "https://api.github.com/repos/stedolan/jq/commits/54b9c9bdb225af5d886466d72f47eafc51acb4f7",
"html_url": "https://github.com/stedolan/jq/commit/54b9c9bdb225af5d886466d72f47eafc51acb4f7"
},
{
"sha": "8b1b503609c161fea4b003a7179b3fbb2dd4345a",
"url": "https://api.github.com/repos/stedolan/jq/commits/8b1b503609c161fea4b003a7179b3fbb2dd4345a",
"html_url": "https://github.com/stedolan/jq/commit/8b1b503609c161fea4b003a7179b3fbb2dd4345a"
}
]
We want to pull out all of the "html_url" fields inside that array of parent
commits and make a simple list of strings to go along with the
"message" and "author" fields we already have.
- command: "jq '[.[] | {message: .commit.message, name: .commit.committer.name, parents: [.parents[].html_url]}]'"
result: |

[sig/v1.5/sha256sum.txt](https://raw.githubusercontent.com/stedolan/jq/master/sig/v1.5/sha256sum.txt).
Additionally, all binaries are signed by the
[jq Package Signing Key](https://raw.githubusercontent.com/stedolan/jq/master/sig/jq-release.key).
The signatures can be found under
[sig/v1.x/\*.asc](https://github.com/stedolan/jq/tree/master/sig).
The signatures for jq 1.5 are in
[sig/v1.5/\*.asc](https://github.com/stedolan/jq/tree/master/sig/v1.5).
You can use [GnuPG](https://gnupg.org/) to verify a signature by downloading
the signature and running `gpg --verify signature.asc`.
### From source on Linux, OS X, Cygwin, and other POSIX-like operating systems
* [Source tarball for jq 1.5](https://github.com/stedolan/jq/releases/download/jq-1.5/jq-1.5.tar.gz)
You can build it using the usual `./configure && make && sudo
make install` rigmarole.
If you're interested in using the lastest development version, try:
git clone https://github.com/stedolan/jq.git
cd jq
autoreconf -i
./configure --disable-maintainer-mode
make
sudo make install
To build it from a git clone, you'll need to install a few
packages first:
* [GCC](https://gcc.gnu.org)
* [Make](https://www.gnu.org/software/make/)
* [Autotools](https://www.gnu.org/software/automake/)
For Linux systems, these will all be in your system's package
manager, and if you do development on the machine they're most
likely already installed.
On OS X, these are all included in Apple's command line tools, which can
be installed from [Xcode](https://developer.apple.com/xcode/). However,
you may find that you need a newer version of Bison than the one provided
by Apple. This can be found in [Homebrew](http://brew.sh) or
[MacPorts](https://macports.org/).
The `--disable-maintainer-mode` flag says to use the pre-generated lexer
and parser that come with the code. To compile the lexer and parser also
from source, leave out this flag. You will need to install
[Flex](http://flex.sourceforge.net/) and
[Bison](https://www.gnu.org/software/bison/).
#### Building the documentation
jq's documentation is compiled into static HTML using
[Bonsai](http://www.tinytree.info). To view the documentation
locally, run `rake serve` (or `bundle exec rake serve`) from the
docs/ subdirectory. To build the docs just `rake build` from the
docs subdirectory. You'll need a few Ruby dependencies, which can
be installed by following the instructions in `docs/README.md`.
The man page is built by `make jq.1`, or just `make`, also from
the YAML docs, and you'll still need the Ruby dependencies to
build the manpage.

jq is written in C and has no runtime dependencies, so it should be
possible to build it for nearly any platform. The prebuilt files linked
below are standalone executables, not archives, and are available for
Linux, macOS and Windows.
The binaries should just run, but on macOS and Linux you may need
to make them executable first using `chmod +x jq`.
jq is licensed under the MIT license. For all of the gory
details, read the file `COPYING` in the source distribution.
jq uses a C library for decimal number support. This is an ICU 1.8.1
licensed code obtained from the ICU downloads archive.

### Checksums and signatures
SHA-256 checksums are provided for all release and pre-release binaries,
and all release artifacts are signed by a jq release key. We have two release keys,
[one for 1.6 and older releases](https://raw.githubusercontent.com/jqlang/jq/master/sig/jq-release-old.key),
and
[one for 1.7 and newer releases](https://raw.githubusercontent.com/jqlang/jq/master/sig/jq-release-new.key).
You can use [GnuPG](https://gnupg.org/) to verify a signature by downloading
the signature and running `gpg --verify signature.asc`.

#### Building the documentation
jq's documentation is compiled into static HTML using Python.
To build the docs, run `pipenv run python3 build_website.py`
in the `docs/` directory. To serve them locally, you can run
`python3 -m http.server -d output`. You'll need a few Python dependencies,
which can be installed by following the instructions in `docs/README.md`.
The man page is built by `make jq.1`, or just `make`, also from

jq is a command-line JSON processor: it reads JSON, applies the program you
give it, and writes JSON back out. A jq program is called a filter, and the
simplest one is `.`, the identity filter, which produces its input unchanged.

The value is unchanged, but the formatting is jq's own: it pretty-prints and
colorizes what it writes, so `jq .` alone is already a useful way to make dense
JSON readable. Note the quotes around the program. The shell has no special
meaning for `.`, so `jq .` works without them, but almost every program past
this one contains characters the shell would interpret itself. Quoting is a
habit worth forming early. (On Windows, `cmd.exe` wants double quotes around
the program instead, and any double quote inside it then needs a backslash.)

For something more substantial, let's use GitHub's API. The `gh`
command-line tool speaks it, so this asks for the commits made to the jq
repository before a fixed date and saves the answer:
gh api 'repos/jqlang/jq/commits?until=2026-09-02' > commits.json
(If you do not have `gh`, `curl -s
'https://api.github.com/repos/jqlang/jq/commits?until=2026-09-02' >
commits.json` fetches the same commits. GitHub pretty-prints what it sends to
`curl`, so that file arrives spread over a couple of thousand lines rather
than the single line shown just below; every jq command here gives the same
answer either way.)
- text: |
jq reads the file you name on the command line, or standard input if you name
none, so piping `gh api` straight into `jq` would work just as well, and day
to day that is how you would write it. In this tutorial, we save the response
to a file so you can follow along without downloading it repeatedly. `until`
pins the result to a fixed set of commits, so what you see matches what is
shown here.

That is a lot of metadata for one commit. Paths chain as far as you need, so
the commit message is:
- command: "jq '.[0].commit.message' commits.json"
result: |
"build(deps): bump markdown from 3.10.2 to 3.10.3 in /docs (#3622)"
- text: |
The result is a JSON string, quotes and all, because jq writes JSON. When
the value is destined for something that wants plain text, `-r` writes
strings raw instead:
- command: "jq -r '.[0].commit.message' commits.json"
result: |
build(deps): bump markdown from 3.10.2 to 3.10.3 in /docs (#3622)

Most of that commit object is noise. To keep only the interesting parts, build
a new object out of them:
- command: "jq '.[0] | {message: .commit.message, author: .commit.author.name}' commits.json"
result: |
{
"message": "build(deps): bump markdown from 3.10.2 to 3.10.3 in /docs (#3622)",

Two things are happening here. `|` is jq's pipe, borrowed from the shell and
working the same way: it feeds the output of the filter on its left into the
input of the filter on its right. So `.[0]` selects the first commit, and
everything after the pipe is evaluated with that commit as its input. And
`{...}` constructs an object, with each value written as a filter applied to
that input.
Replacing `.[0]` with `.[]` runs the same construction over every element of
the array:
- command: "jq '.[] | {message: .commit.message, author: .commit.author.name}' commits.json"
result: |

Thirty objects, not an array of thirty objects. This is central to how jq works:
a jq program transforms a *stream* of JSON values. Every expression runs
once per value in its input stream and may produce any number of values -
zero, one, or many - on its output stream. `.[]` is simply an expression
that takes one array and emits each of its elements.
Every value jq writes is followed by a newline. Reading is more relaxed than
writing: any amount of whitespace between two values will do, and a value that
closes with `}`, `]` or `"` needs no separator at all. That is what makes the
format `cat`-friendly:
join two jq outputs together and the result is still something jq can read. A
pretty-printed value spans as many lines as it needs, so when the next program
in the pipeline is line-oriented, `-c` is what you want. It compacts each value
onto one line:
- command: "jq -c '.[] | {message: .commit.message, author: .commit.author.name}' commits.json"

Note that the names came back sorted. That is not incidental: `unique` finds
duplicates by ordering the array first, and that order is what you get. To sort
on purpose there is `sort`, and `first` and `last` pick the ends off the sorted
array - between them, the stretch of time these thirty commits cover:
- command: "jq 'map(.commit.author.date) | sort | [first, last]' commits.json"
result: |
[
"2026-05-05T05:06:45Z",
"2026-09-01T06:30:46Z"
]
- text: |
`sort_by(f)` is the general form: it orders whole elements by whatever `f`
extracts. That is what you need as soon as the answer involves more than the
key you sorted on - the same two ends, now with their authors attached:
- command: "jq 'sort_by(.commit.author.date) | [first, last] | map({author: .commit.author.name, date: .commit.author.date})' commits.json"
result: |
[
{
"author": "itchyny",
"date": "2026-05-05T05:06:45Z"
},
{
"author": "dependabot[bot]",
"date": "2026-09-01T06:30:46Z"
}

- text: |
`sort` could not have done that. It sees only the values it is given, so the
dates would have arrived with nothing attached; `sort_by` keeps whole commits
and merely puts them in order.
- text: |
`group_by(f)` gathers the elements that agree on `f` into sub-arrays, so an
array of thirty commits becomes an array of arrays. It orders them by `f` on
the way, just as `unique` does, which is where the sorted order below
comes from. This is the usual way to count things:
- command: "jq 'group_by(.commit.author.name) | map({author: .[0].commit.author.name, commits: length})' commits.json"

Each group is still a full array of commit objects, so `.[0].commit.author.name`
reads the author off its first member and `length` counts the members.
`unique_by`, `min_by` and `max_by` take a filter the same way `sort_by` does,
and `add` folds an array down to a single value.
- text: |

An expression that produces *no* output for some inputs is how filtering works.
`select(condition)` emits its input unchanged when the condition is true, and
nothing at all when it is not, so putting one in the middle of a pipeline
drops the values you do not want. What it passes on is the whole value, not
just the part the condition looked at. A filter can therefore test one field
and then go on to read another - here, finding the commits dependabot made and
printing what they say:
- command: "jq -r '.[] | select(.commit.author.name == \"dependabot[bot]\") | .commit.message' commits.json"

Conditions join up with `and` and `or`. Piping into the field first lets the
path be written once, with both comparisons reading `.`. That widens the test
to catch the other bot too:

One more commit than before, and pairing each message with its author shows
which of the two clauses caught it. Negation is the odd one out of the three:
jq has no `!`, and `not` is a filter like any other, so it takes its argument
from the left. `select` also works on any value, not just objects, so a plain
string can flow straight into the test - here, the people rather than the bots
behind these thirty commits:

`test` looks anywhere in the string, so it finds the `Fixes CVE-...` line down
in a commit body even where the subject says nothing about it. Flags go in a
second argument: `test("fix"; "i")` ignores case.

Everything so far has started from an array - `.[]` to open one up, then `map`,
`sort`, `select`. `.[]` and `map` work on objects too, but they see only the
values. `to_entries` turns an object into an array of key/value pairs, which is
how you reach an object's keys when they are data rather than something you
typed:
- command: "jq '.[0].commit.author | to_entries' commits.json"
result: |
[
{
"key": "name",
"value": "dependabot[bot]"
},
{
"key": "email",
"value": "49699333+dependabot[bot]@users.noreply.github.com"
},
{
"key": "date",
"value": "2026-09-01T06:30:46Z"
}
]
- text: |
`from_entries` goes the other way, building an object out of pairs. That turns
the author counts from earlier into a lookup table:
- command: "jq 'group_by(.commit.author.name) | map({key: .[0].commit.author.name, value: length}) | from_entries' commits.json"
result: |
{
"A4-Tacks": 1,

"WinkleMad": 1,
"Yu-Fu Fu": 1,

"dependabot[bot]": 5,
"github-actions[bot]": 1,
"itchyny": 13,
"pavel kuliaka": 1,
"theyoucheng": 1
}
- text: |
`with_entries(f)` is that round trip in one step - `to_entries | map(f) |
from_entries` - running `f` over each pair, so a `select` there keeps or drops
whole fields. Next to `commit`, each element of the response carries three
links to the commit, and this keeps just those by testing each key as it goes
past:
- command: "jq '.[0] | with_entries(select(.key | endswith(\"url\")))' commits.json"
result: |
{
"url": "https://api.github.com/repos/jqlang/jq/commits/9d241e277204b83c4a7ddc7d733e5c72f99ef500",
"html_url": "https://github.com/jqlang/jq/commit/9d241e277204b83c4a7ddc7d733e5c72f99ef500",

}
- text: |
Inside `f` a pair is just an object, so `.key` and `.value` are ordinary paths.
`|=` updates a path in place, running a filter on whatever value it finds
there, so `with_entries(.key |= ascii_downcase)` would lowercase every field
name.
- text: |
Values can be built as well as pulled out. Inside a string, `\(...)` substitutes
the result of a filter, and `[a:b]` slices strings and arrays - between them
enough to turn each commit into a one-line log entry:
- command: "jq -r '.[] | \"\\(.sha[0:7]) \\(.commit.author.name)\"' commits.json"
result: |

The pieces combine. `map(select(...))` is the ordinary way to filter an array:
`map` visits every element and `select` decides whether it survives, so the
`endswith("[bot]") | not` from before clears out dependabot and friends.
`group_by` and `sort_by` then do what they did above. jq sorts ascending, so
negating the key is how you ask for largest-first; `reverse` does the same job
for keys that cannot be negated. `@tsv` joins each pair into a tab-separated
line, giving a plain-text leaderboard of the humans:
- command: "jq -r 'map(select(.commit.author.name | endswith(\"[bot]\") | not)) | group_by(.commit.author.name) | map({author: .[0].commit.author.name, commits: length}) | sort_by(-.commits) | .[] | [.commits, .author] | @tsv' commits.json"

Seven stages, each doing one thing to the value it receives: drop the bots,
group what is left by author, count each group, put the counts in order, take
the array apart again, pair each count with its author, and join the pair into
a line. Most real jq programs are built exactly this way.
- text: |
- - -
That is the core of it: paths to reach into a document, `|` to chain
filters, `[]` and `{}` to take structures apart and put new ones back
together, and streams tying it all together. Everything else is built on
those.
There is plenty more: arithmetic, variables and conditionals; updating a
document in place; `@base64`, `@uri` and the other `@` formats; `reduce` and
`foreach` for folding over a stream; `inputs` and the rest of the
IO builtins for reading many values instead of one; and defining your own
functions on top of a large library of builtins. Go read
[the manual](../manual/) when you need it, and [download jq](../download/) if
you have not already.

# SYNOPSIS
#
# AX_PTHREAD([ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]])
#
# DESCRIPTION
#
# This macro figures out how to build C programs using POSIX threads. It
# sets the PTHREAD_LIBS output variable to the threads library and linker
# flags, and the PTHREAD_CFLAGS output variable to any special C compiler
# flags that are needed. (The user can also force certain compiler
# flags/libs to be tested by setting these environment variables.)
#
# Also sets PTHREAD_CC and PTHREAD_CXX to any special C compiler that is
# needed for multi-threaded programs (defaults to the value of CC
# respectively CXX otherwise). (This is necessary on e.g. AIX to use the
# special cc_r/CC_r compiler alias.)
#
# NOTE: You are assumed to not only compile your program with these flags,
# but also to link with them as well. For example, you might link with
# $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS $LIBS
# $PTHREAD_CXX $CXXFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS $LIBS
#
# If you are only building threaded programs, you may wish to use these
# variables in your default LIBS, CFLAGS, and CC:
#
# LIBS="$PTHREAD_LIBS $LIBS"
# CFLAGS="$CFLAGS $PTHREAD_CFLAGS"
# CXXFLAGS="$CXXFLAGS $PTHREAD_CFLAGS"
# CC="$PTHREAD_CC"
# CXX="$PTHREAD_CXX"
#
# In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute constant
# has a nonstandard name, this macro defines PTHREAD_CREATE_JOINABLE to
# that name (e.g. PTHREAD_CREATE_UNDETACHED on AIX).
#
# Also HAVE_PTHREAD_PRIO_INHERIT is defined if pthread is found and the
# PTHREAD_PRIO_INHERIT symbol is defined when compiling with
# PTHREAD_CFLAGS.
#
# ACTION-IF-FOUND is a list of shell commands to run if a threads library
# is found, and ACTION-IF-NOT-FOUND is a list of commands to run it if it
# is not found. If ACTION-IF-FOUND is not specified, the default action
# will define HAVE_PTHREAD.
#
# Please let the authors know if this macro fails on any platform, or if
# you have any other suggestions or comments. This macro was based on work
# by SGJ on autoconf scripts for FFTW (http://www.fftw.org/) (with help
# from M. Frigo), as well as ac_pthread and hb_pthread macros posted by
# Alejandro Forero Cuervo to the autoconf macro repository. We are also
# grateful for the helpful feedback of numerous users.

# Clang needs special handling, because older versions handle the -pthread
# option in a rather... idiosyncratic way
if test "x$ax_pthread_clang" = "xyes"; then
# Clang takes -pthread; it has never supported any other flag
# (Note 1: This will need to be revisited if a system that Clang
# supports has POSIX threads in a separate library. This tends not
# to be the way of modern systems, but it's conceivable.)
# (Note 2: On some systems, notably Darwin, -pthread is not needed
# to get POSIX threads support; the API is always present and
# active. We could reasonably leave PTHREAD_CFLAGS empty. But
# -pthread does define _REENTRANT, and while the Darwin headers
# ignore this macro, third-party headers might not.)
# However, older versions of Clang make a point of warning the user
# that, in an invocation where only linking and no compilation is
# taking place, the -pthread option has no effect ("argument unused
# during compilation"). They expect -pthread to be passed in only
# when source code is being compiled.
#
# Problem is, this is at odds with the way Automake and most other
# C build frameworks function, which is that the same flags used in
# compilation (CFLAGS) are also used in linking. Many systems
# supported by AX_PTHREAD require exactly this for POSIX threads
# support, and in fact it is often not straightforward to specify a
# flag that is used only in the compilation phase and not in
# linking. Such a scenario is extremely rare in practice.
#
# Even though use of the -pthread flag in linking would only print
# a warning, this can be a nuisance for well-run software projects
# that build with -Werror. So if the active version of Clang has
# this misfeature, we search for an option to squash it.
