jq

# jq

`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.

## Installation

### Prebuilt Binaries

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`.

### Docker Image

Pull the [jq image](https://github.com/jqlang/jq/pkgs/container/jq) to start quickly with Docker.

#### Run with Docker

##### Example: Extracting the version from a `package.json` file

```bash
docker run --rm -i ghcr.io/jqlang/jq:latest < package.json '.version'
```

##### Example: Extracting the version from a `package.json` file with a mounted volume

```bash
docker run --rm -i -v "$PWD:$PWD" -w "$PWD" ghcr.io/jqlang/jq:latest '.version' package.json
```

### Building from source

#### Dependencies

- libtool
- make
- automake
- autoconf

#### Instructions

```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
```

Build a statically linked version:

```console
make clean
make LDFLAGS=-all-static
```

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
