+      default
+
+ - syntax
+
+    - .. -> like // in XPath (recursive traversal)

 If you want to learn to use jq, read the documentation at
-[http://stedolan.github.com/jq](http://stedolan.github.com/jq). This
+[https://jqlang.github.io/jq](https://jqlang.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).

 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: http://github.com/stedolan/jq/wiki
+shovel.  Also, read the wiki: https://github.com/jqlang/jq/wiki, where
+you will find cookbooks, discussion of advanced topics, internals,
+release engineering, and more.

-To build jq, run
+Source tarball and built executable releases can be found on the
+homepage and on the github release page, https://github.com/jqlang/jq/releases

+If you're building directly from the latest git, you'll need flex,
+bison (3.0 or newer), libtool, make, automake, and autoconf installed.
+To get regexp support you'll also need to install Oniguruma or clone it as a
+git submodule as per the instructions below.
+(note that jq's tests require regexp support to pass).  To build, run:
+
+    git submodule update --init # if building from git to get oniguruma
+    autoreconf -fi              # if building from git
+    ./configure --with-oniguruma=builtin
+    make -j8
+    make check
+
+To build without bison or flex, add `--disable-maintainer-mode` to the
+./configure invocation:
+
+    ./configure --with-oniguruma=builtin --disable-maintainer-mode
+
+(Developers must not use `--disable-maintainer-mode`, not when making
+changes to the jq parser and/or lexer.)
+
+To build a statically linked version of jq, run:
+
+    make LDFLAGS=-all-static
+
+After make finishes, you'll be able to use `./jq`.  You can also
+install it using:
+
+    sudo make install
+
+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.
+
+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.
+
+Cross-compilation requires a clean workspace, then:
+
+    # git clean ...
+    autoreconf -i
    ./configure
-    make
-    sudo make install (optionally)
+    make distclean
+    scripts/crosscompile <name-of-build> <configure-options>

-If you've just checked out the latest version from git (rather than
-using a released source tarball) then you'll need to run this first:
+Use the `--host=` and `--target=` ./configure options to select a
+cross-compilation environment.  See also
+["Cross compilation"](https://github.com/jqlang/jq/wiki/Cross-compilation) on
+the wiki.

+# 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.

 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
+you have pipenv installed, you can install the dependencies by running
+`pipenv install` 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:
+Once this is done, rerun `./configure` in the jq root directory and then

-    bundle install

-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 ./build_website.py` from inside
+the `docs` directory.

-      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).

-      `.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: |
-      [
-        {

-            ]
-          }
-
-      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).
-
-       * Debian/Ubuntu packages are coming Real Soon Now.
-
-      ### 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
-
-          git clone https://github.com/stedolan/jq.git
-          cd jq
-          make && 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/)
-       * [Python](http://www.python.org)
-       * [GCC](http://gcc.gnu.org)
-       * [Make](http://www.gnu.org/software/make)
-
-      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.

+      [sig/v1.5/sha256sum.txt](https://raw.githubusercontent.com/jqlang/jq/master/sig/v1.5/sha256sum.txt).
+
+      Additionally, all binaries are signed by the
+      [jq Package Signing Key](https://raw.githubusercontent.com/jqlang/jq/master/sig/jq-release.key).
+      The signatures can be found under
+      [sig/v1.x/\*.asc](https://github.com/jqlang/jq/tree/master/sig).
+      The signatures for jq 1.6 are in
+      [sig/v1.5/\*.asc](https://github.com/jqlang/jq/tree/master/sig/v1.6).
+      The signatures for jq 1.5 are in
+      [sig/v1.5/\*.asc](https://github.com/jqlang/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, macOS, Cygwin, and other POSIX-like operating systems
+
+       * [Source tarball for jq 1.6](https://github.com/jqlang/jq/releases/download/jq-1.6/jq-1.6.tar.gz)
+       * [Source tarball for jq 1.5](https://github.com/jqlang/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 --recursive https://github.com/jqlang/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 macOS, 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](https://github.com/westes/flex) 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.

-  jq is a lightweight and flexible command-line JSON processor.
-  
-body1: |
-
-  jq is like `sed` for JSON data - you can use it to slice and filter
-  and map and transform structured data with the same ease that `sed`,
-  `awk`, `grep` and friends let you play with text.
-
-body2: |
-
-  jq is written in portable C, and it has zero runtime
-  dependencies. You can download a single binary, `scp` it to a far away
-  machine, and expect it to work.
-
-body3: |
-
-  jq can mangle the data format that you have into the one that you
-  want with very little effort, and the program to do so is often
-  shorter and simpler than you'd expect.

+
+      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}'"

+
+      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": "docs: Document repeat(exp)",

+        "message": "Mention -n in IO-section and for input/inputs",
+        "name": "Nico Williams"
+      }
+      {
+        "message": "Fix iterration problem for non decimal string\n\nWhen the string transformation to number failed, all following\ntransformation failed too.\n\nThis happend because status in decNumberFromString function is\nupdated just in error case. Reusing the DEC_CONTEXT that failed\nbefore results into error even if the string is valid number.",
+        "name": "Nico Williams"
+      }
+      {
+        "message": "docs: point to Libera.Chat instead of Freenode",

+        "name": "Nico 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: |
+      [
+        {

+
+      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": [

+          ]
+
+      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.

-jq(1) -- Command-line JSON processor
-====================================
-
-## 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:
-
-    https://github.com/stedolan/jq/issues
