 To build the documentation (including building the jq manpage), you'll

+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 <http://rvm.io> for more info on RVM.
+Though, you may need to say pip3 instead, depending on your system. Once

-      Twitter has a JSON API, so let's play with that. This URL gets

-      For the rest of the examples, I'll leave out the `curl` command - it's not going to change.
-
-    
-      There's still a lot of info we don't care about there, so we'll
-      restrict it down to the most interesting fields.

-      The `|` operator in jq feeds the output of one filter
-      (`.results[0]` which gets the first element of the results
-      array) into the input of another (`{from_user, text}` which
-      builds an object of those two fields).
-    
-      Now let's get the rest of the tweets:
-    
-          
-
-  - command: "jq '.results[] | {from_user, text}'"
-    result: |

-  - text: |
-    
-      `.results[]` returns each element of the results array, one at a
-      time, which are all fed into `{from_user, text}`.
-
-
-      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 '[.results[] | {from_user, text}]'"
-    result: |
-      [
-        {
-          "text": "RT @imagemechanics: iPhone 5 website teardown: How Apple compresses video using JPEG, JSON, and &lt;canvas&gt;.\nhttp://t.co/XRvh1ZVw",
-          "from_user": "_AaronNg"
-        },
-        {

-      Next, let's try getting the URLs out of those API results as
-      well. In each tweet, the Twitter API includes a field called
-      "entities" which looks like this:
-
-          {
-            "user_mentions": [],
-            "urls": [{
-                "indices": [83, 103],

-                "expanded_url": "http://bit.ly/StniqT",
-                "url": "http://t.co/28Jesbio"

-              {"indices": [108, 114], "text": "Apple" },
-              {"indices": [121, 129], "text": "Awesome"}
-            ]
-          }
-
-      We want to pull out all of the "url" fields inside that array of url
-      objects, and make a simple list of strings to go along with the
-      "from_user" and "text" fields we already have.
-    
-

-
-      jq is written in C and has no runtime dependencies, so it should be
-      possible to build it for nearly any platform. Prebuilt binaries are
-      available for Linux, OS X and Windows.
-
-      The binaries should just run, but on OS X 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.
-
-
-      ### Linux
-      
-       * Binaries for [64-bit](linux64/jq) or [32-bit](linux32/jq) systems.
-
-       * For Arch users, a PKGBUILD for jq-1.1 is in the
-         [AUR](https://aur.archlinux.org/packages.php?ID=63849), as
-         well as a PKGBUILD for the HEAD of master
-         ([jq-git](https://aur.archlinux.org/packages.php?ID=63850)).
-         You can install them using
-         [Yaourt](https://wiki.archlinux.org/index.php/Yaourt) or
-         manually by following instructions on [Arch Linux's
-         Wiki](https://wiki.archlinux.org/index.php/Arch_UseRepository).
-
-       * jq 1.2 is [in Debian](http://packages.debian.org/jq)
-
-      ### OS X
-
-       * `brew install jq` using [homebrew](http://mxcl.github.com/homebrew/)
-
-       * Or, grab prebuilt [64-bit binaries](osx64/jq) or [32-bit
-         binaries](osx32/jq)
-
-      ### Windows
-
-       * Executables for [64-bit](win64/jq.exe) or [32-bit](win32/jq.exe)
-
-      ### From source on Linux or OS X
-
-       * [Source tarball for jq $JQ_VERSION](source/jq-$JQ_VERSION.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

-          ./configure

-          sudo make install
-
-      To build it from a git clone, you'll need to install a few
-      packages first:
-
-       * [Flex](http://www.gnu.org/software/flex/)
-       * [Bison](http://www.gnu.org/software/bison/)
-       * [GCC](http://gcc.gnu.org)
-       * [Make](http://www.gnu.org/software/make)
-       * [Autotools](http://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](http://developer.apple.com/technologies/tools/).
-      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://mxcl.github.com/homebrew/)
-      or [MacPorts](http://macports.org/).
-
-      `flex` and `bison` are used to generate the lexer and parser for
-      jq, and some python scripts generate the UTF8 encoding tables
-      needed for JSON parsing.

-      #### 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` from the docs/ subdirectory. You'll
-      need a few Ruby dependencies, which can be installed by
-      following the instructions in `docs/README.md`.

+
+      jq is written in C and has no runtime dependencies, so it should be
+      possible to build it for nearly any platform. Prebuilt binaries are
+      available for Linux, OS X and Windows.
+
+      The binaries should just run, but on OS X 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.
+
+
+      ### Linux

+      SHA-256 checksums are provided for all release and pre-release binaries.
+      They can be found under
+      [sig/v1.x/sha256sum.txt](https://github.com/stedolan/jq/tree/master/sig).

+      [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 1.6 are in
+      [sig/v1.5/\*.asc](https://github.com/stedolan/jq/tree/master/sig/v1.6).
+      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 1.6](https://github.com/stedolan/jq/releases/download/jq-1.6/jq-1.6.tar.gz)
+       * [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

+      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 Python.
+      To build the docs, run `pipenv run python3 build_website.py` from
+      the docs/ subdirectory. To serve them locally, you can run
+      `python3 -m SimpleHTTPServer`. 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
+      the YAML docs, and you'll still need the Python dependencies to
+      build the manpage.

          In jq, all filters have an input and an output, so manual
          plumbing is not necessary to pass a value from one part of a program
          to the next. Many expressions, for instance `a + b`, pass their input
          to two distinct subexpressions (here `a` and `b` are both passed the
          same input), so variables aren't usually necessary in order to use a
          value twice.
-          
+
          For instance, calculating the average value of an array of numbers
          requires a few variables in most languages - at least one to hold the
          array, perhaps one for each element or for a loop counter. In jq, it's
          simply `add / length` - the `add` expression is given the array and
          produces its sum, and the `length` expression is given the array and
          produces its length.
-          
+
          So, there's generally a cleaner way to solve most problems in jq that
          defining variables. Still, sometimes they do make things easier, so jq
          lets you define variables using `expression as $variable`. All
          variable names start with `$`. Here's a slightly uglier version of the
          array-averaging example:
-          
+
              length as $array_length | add / $array_length
-

          We'll need a more complicated problem to find a situation where using
          variables actually makes our lives easier.

+
          Suppose we have an array of blog posts, with "author" and "title"
          fields, and another object which is used to map author usernames to
          real names. Our input looks like:
-          
+
              {"posts": [{"title": "Frist psot", "author": "anon"},
                         {"title": "A well-written article", "author": "person1"}],
               "realnames": {"anon": "Anonymous Coward",
                             "person1": "Person McPherson"}}
-          
+
          We want to produce the posts with the author field containing a real
          name, as in:
-          
+
              {"title": "Frist psot", "author": "Anonymous Coward"}
              {"title": "A well-written article", "author": "Person McPherson"}
-          
+
          We use a variable, $names, to store the realnames object, so that we
          can refer to it later when looking up author usernames:
-          
+
              .realnames as $names | .posts[] | {title, author: $names[.author]}
-          
+
          The expression `exp as $x | ...` means: for each value of expression
          `exp`, run the rest of the pipeline with the entire original input, and
-          with `$x` set to that value.  Thus `as` functions as something of a

          Lots more things are allowed on the left-hand side of a jq assignment
          than in most langauges. We've already seen simple field accesses on
          the left hand side, and it's no surprise that array accesses work just
          as well:
-          
+
              .posts[0].title = "JQ Manual"
-          
+
          What may come as a surprise is that the expression on the left may
          produce multiple results, referring to different points in the input
          document:
-          
+
              .posts[].comments |= . + ["this is great"]
-          
+
          That example appends the string "this is great" to the "comments"
          array of each post in the input (where the input is an object with a
          field "posts" which is an array of posts).
-          
+
          When jq encounters an assignment like 'a = b', it records the "path"
          taken to select a part of the input document while executing a. This
          path is then used to find which part of the input to change while
          executing the assignment. Any filter may be used on the
          left-hand side of an equals - whichever paths it selects from the
          input will be where the assignment is performed.
-          
+
          This is a very powerful operation. Suppose we wanted to add a comment
          to blog posts, using the same "blog" input above. This time, we only
          want to comment on the posts written by "stedolan". We can find those
          posts using the "select" function described earlier:
-          
+
              .posts[] | select(.author == "stedolan")
-          
+
          The paths provided by this operation point to each of the posts that
          "stedolan" wrote, and we can comment on each of them in the same way
          that we did before:
-

              (.posts[] | select(.author == "stedolan") | .comments) |=

+
+      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.",
+          "name": "Stephen Dolan"
+        },
+        {
+          "message": "Fix example in manual for `floor`. See #155.",
+          "name": "Stephen Dolan"
+        },
+        {
+          "message": "Document floor",

+        }

+
+      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",

+          ]
+
+      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]}]'"

-## DESCRIPTION
-
-`jq` can transform JSON in various ways, by selecting, iterating,
-reducing and otherwise mangling JSON documents. 
-
-This version of `jq` was built without a manual, so this manpage is a
-stub. For full documentation of the `jq` language, see:
-
-    http://stedolan.github.com/jq
-    
-## BUGS
-
-Presumably. Report them or discuss them at:

+# SYNOPSIS
+#
+#   AX_COMPARE_VERSION(VERSION_A, OP, VERSION_B, [ACTION-IF-TRUE], [ACTION-IF-FALSE])
+#
+# DESCRIPTION
+#
+#   This macro compares two version strings. Due to the various number of
+#   minor-version numbers that can exist, and the fact that string
+#   comparisons are not compatible with numeric comparisons, this is not
+#   necessarily trivial to do in a autoconf script. This macro makes doing
+#   these comparisons easy.
+#
+#   The six basic comparisons are available, as well as checking equality
+#   limited to a certain number of minor-version levels.
+#
+#   The operator OP determines what type of comparison to do, and can be one
+#   of:
+#
+#    eq  - equal (test A == B)
+#    ne  - not equal (test A != B)
+#    le  - less than or equal (test A <= B)
+#    ge  - greater than or equal (test A >= B)
+#    lt  - less than (test A < B)
+#    gt  - greater than (test A > B)
+#
+#   Additionally, the eq and ne operator can have a number after it to limit
+#   the test to that number of minor versions.
+#
+#    eq0 - equal up to the length of the shorter version
+#    ne0 - not equal up to the length of the shorter version
+#    eqN - equal up to N sub-version levels
+#    neN - not equal up to N sub-version levels
+#
+#   When the condition is true, shell commands ACTION-IF-TRUE are run,
+#   otherwise shell commands ACTION-IF-FALSE are run. The environment
+#   variable 'ax_compare_version' is always set to either 'true' or 'false'
+#   as well.
+#
+#   Examples:
+#
+#     AX_COMPARE_VERSION([3.15.7],[lt],[3.15.8])
+#     AX_COMPARE_VERSION([3.15],[lt],[3.15.8])
+#
+#   would both be true.
+#
+#     AX_COMPARE_VERSION([3.15.7],[eq],[3.15.8])
+#     AX_COMPARE_VERSION([3.15],[gt],[3.15.8])
+#
+#   would both be false.
+#
+#     AX_COMPARE_VERSION([3.15.7],[eq2],[3.15.8])
+#
+#   would be true because it is only comparing two minor versions.
+#
+#     AX_COMPARE_VERSION([3.15.7],[eq0],[3.15])
+#
+#   would be true because it is only comparing the lesser number of minor
+#   versions of the two values.
+#
+#   Note: The characters that separate the version numbers do not matter. An
+#   empty string is the same as version 0. OP is evaluated by autoconf, not
+#   configure, so must be a string, not a variable.
+#
+#   The author would like to acknowledge Guido Draheim whose advice about
+#   the m4_case and m4_ifvaln functions make this macro only include the
+#   portions necessary to perform the specific comparison specified by the
+#   OP argument in the final configure script.

+#   AX_PROG_BISON_VERSION([VERSION],[ACTION-IF-TRUE],[ACTION-IF-FALSE])
+#
+# DESCRIPTION
+#
+#   Makes sure that bison supports the version indicated. If true the shell
+#   commands in ACTION-IF-TRUE are executed. If not the shell commands in
+#   ACTION-IF-FALSE are run. Note if $PERL is not set the macro will fail.
+#
+#   Example:
+#
+#     AC_PROG_YACC
+#     AX_PROG_BISON_VERSION([3.0.0],[ ... ],[ ... ])
+#
+#   This will check to make sure that the bison you have supports at least
+#   version 3.0.0.
+#
+#   NOTE: This macro uses the $YACC variable to perform the check.
+#   AX_WITH_YACC can be used to set that variable prior to running this
+#   macro. The $BISON_VERSION variable will be set with the detected
+#   version.
