![Tests](https://github.com/kellyjonbrazil/jc/workflows/Tests/badge.svg?branch=master) ![Pypi](https://img.shields.io/pypi/v/jc.svg) # JC JSON CLI output utility `jc` JSONifies the output of many CLI tools and file-types for easier parsing in scripts. See the [**Parsers**](#parsers) section for supported commands and file-types. This allows further command-line processing of output with tools like `jq` by piping commands: ```bash ls -l /usr/bin | jc --ls | jq '.[] | select(.size > 50000000)' ``` ```json { "filename": "docker", "flags": "-rwxr-xr-x", "links": 1, "owner": "root", "group": "root", "size": 68677120, "date": "Aug 14 19:41" } ``` or using the alternative "magic" syntax: ```bash jc ls -l /usr/bin | jq '.[] | select(.size > 50000000)' ``` ```json { "filename": "docker", "flags": "-rwxr-xr-x", "links": 1, "owner": "root", "group": "root", "size": 68677120, "date": "Aug 14 19:41" } ``` The `jc` parsers can also be used as python modules. In this case the output will be a python dictionary, or list of dictionaries, instead of JSON: ```python >>> import jc.parsers.ls >>> >>> data='''-rwxr-xr-x 1 root wheel 23648 May 3 22:26 cat ... -rwxr-xr-x 1 root wheel 30016 May 3 22:26 chmod ... -rwxr-xr-x 1 root wheel 29024 May 3 22:26 cp ... -rwxr-xr-x 1 root wheel 375824 May 3 22:26 csh ... -rwxr-xr-x 1 root wheel 28608 May 3 22:26 date ... -rwxr-xr-x 1 root wheel 32000 May 3 22:26 dd ... -rwxr-xr-x 1 root wheel 23392 May 3 22:26 df ... -rwxr-xr-x 1 root wheel 18128 May 3 22:26 echo''' >>> >>> jc.parsers.ls.parse(data) [{'filename': 'cat', 'flags': '-rwxr-xr-x', 'links': 1, 'owner': 'root', 'group': 'wheel', 'size': 23648, 'date': 'May 3 22:26'}, {'filename': 'chmod', 'flags': '-rwxr-xr-x', 'links': 1, 'owner': 'root', 'group': 'wheel', 'size': 30016, 'date': 'May 3 22:26'}, {'filename': 'cp', 'flags': '-rwxr-xr-x', 'links': 1, 'owner': 'root', 'group': 'wheel', 'size': 29024, 'date': 'May 3 22:26'}, {'filename': 'csh', 'flags': '-rwxr-xr-x', 'links': 1, 'owner': 'root', 'group': 'wheel', 'size': 375824, 'date': 'May 3 22:26'}, {'filename': 'date', 'flags': '-rwxr-xr-x', 'links': 1, 'owner': 'root', 'group': 'wheel', 'size': 28608, 'date': 'May 3 22:26'}, {'filename': 'dd', 'flags': '-rwxr-xr-x', 'links': 1, 'owner': 'root', 'group': 'wheel', 'size': 32000, 'date': 'May 3 22:26'}, {'filename': 'df', 'flags': '-rwxr-xr-x', 'links': 1, 'owner': 'root', 'group': 'wheel', 'size': 23392, 'date': 'May 3 22:26'}, {'filename': 'echo', 'flags': '-rwxr-xr-x', 'links': 1, 'owner': 'root', 'group': 'wheel', 'size': 18128, 'date': 'May 3 22:26'}] ``` Two representations of the data are possible. The default representation uses a strict schema per parser and converts known numbers to int/float JSON values. Certain known values of `None` are converted to JSON `null`, known boolean values are converted, and, in some cases, additional semantic context fields are added. To access the raw, pre-processed JSON, use the `-r` cli option or the `raw=True` function parameter in `parse()`. Schemas for each parser can be found in the [`docs/parsers`](https://github.com/kellyjonbrazil/jc/tree/master/docs/parsers) folder. Release notes can be found [here](https://blog.kellybrazil.com/category/jc-news/). ## Why Would Anyone Do This!? For more information on the motivations for this project, please see my [blog post](https://blog.kellybrazil.com/2019/11/26/bringing-the-unix-philosophy-to-the-21st-century/). See also: - [libxo on FreeBSD](http://juniper.github.io/libxo/libxo-manual.html) - [powershell](https://docs.microsoft.com/en-us/powershell/module/microsoft.powershell.utility/convertto-json?view=powershell-7) - [blog: linux apps should have a json flag](https://thomashunter.name/posts/2012-06-06-linux-cli-apps-should-have-a-json-flag) ## Installation There are several ways to get `jc`. You can install via `pip`; other OS package repositories like `dnf`, `zypper`, `nix-env`, `guix`, `brew`, or `portsnap`; via DEB/RPM packages; or by downloading the correct binary for your architecture and running it anywhere on your filesystem. ### Pip (macOS, linux, unix, Windows) ```bash pip3 install jc ``` ### OS Package Repositories | OS | Command | |-----------------------|-------------------------------------------------------------------------------| | Fedora linux | `dnf install jc` | | openSUSE linux | `zypper install jc` | | Arch linux | `pacman -S jc` | | NixOS linux | `nix-env -iA nixpkgs.jc` | | Guix System linux | `guix install jc` | | MacOS | `brew install jc` | | FreeBSD | `portsnap fetch update && cd /usr/ports/textproc/py-jc && make install clean` | > For more packages and binaries, see https://kellyjonbrazil.github.io/jc-packaging/. ## Usage `jc` accepts piped input from `STDIN` and outputs a JSON representation of the previous command's output to `STDOUT`. ```bash COMMAND | jc PARSER [OPTIONS] ``` Alternatively, the "magic" syntax can be used by prepending `jc` to the command to be converted. Options can be passed to `jc` immediately before the command is given. (Note: command aliases are not supported) ```bash jc [OPTIONS] COMMAND ``` The JSON output can be compact (default) or pretty formatted with the `-p` option. ### Parsers - `--airport` enables the `airport -I` command parser (OSX) - `--airport-s` enables the `airport -s` command parser (OSX) - `--arp` enables the `arp` command parser - `--blkid` enables the `blkid` command parser - `--crontab` enables the `crontab` command and file parser - `--crontab-u` enables the `crontab` file parser with user support - `--csv` enables the `CSV` file parser - `--df` enables the `df` command parser - `--dig` enables the `dig` command parser - `--dmidecode` enables the `dmidecode` command parser - `--du` enables the `du` command parser - `--env` enables the `env` command parser - `--file` enables the `file` command parser - `--free` enables the `free` command parser - `--fstab` enables the `/etc/fstab` file parser - `--group` enables the `/etc/group` file parser - `--gshadow` enables the `/etc/gshadow` file parser - `--history` enables the `history` command parser - `--hosts` enables the `/etc/hosts` file parser - `--id` enables the `id` command parser - `--ifconfig` enables the `ifconfig` command parser - `--ini` enables the `INI` file parser - `--iptables` enables the `iptables` command parser - `--jobs` enables the `jobs` command parser - `--last` enables the `last` and `lastb` command parser - `--ls` enables the `ls` command parser - `--lsblk` enables the `lsblk` command parser - `--lsmod` enables the `lsmod` command parser - `--lsof` enables the `lsof` command parser - `--mount` enables the `mount` command parser - `--netstat` enables the `netstat` command parser - `--ntpq` enables the `ntpq -p` command parser - `--passwd` enables the `/etc/passwd` file parser - `--pip-list` enables the `pip list` command parser - `--pip-show` enables the `pip show` command parser - `--ps` enables the `ps` command parser - `--route` enables the `route` command parser - `--shadow` enables the `/etc/shadow` file parser - `--ss` enables the `ss` command parser - `--stat` enables the `stat` command parser - `--systemctl` enables the `systemctl` command parser - `--systemctl-lj` enables the `systemctl list-jobs` command parser - `--systemctl-ls` enables the `systemctl list-sockets` command parser - `--systemctl-luf` enables the `systemctl list-unit-files` command parser - `--timedatectl` enables the `timedatectl status` command parser - `--uname` enables the `uname -a` command parser - `--uptime` enables the `uptime` command parser - `--w` enables the `w` command parser - `--who` enables the `who` command parser - `--xml` enables the `XML` file parser - `--yaml` enables the `YAML` file parser ### Options - `-a` about `jc`. Prints information about `jc` and the parsers (in JSON, of course!) - `-d` debug mode. Prints trace messages if parsing issues encountered (use `-dd` for verbose debugging) - `-m` monochrome JSON output - `-p` pretty format the JSON output - `-q` quiet mode. Suppresses warning messages - `-r` raw output. Provides a more literal JSON output with all values as strings and no additional sematic processing ### Setting Custom Colors via Environment Variable You can specify custom colors via the `JC_COLORS` environment variable. The `JC_COLORS` environment variable takes four comma separated string values in the following format: ```bash JC_COLORS=,,, ``` Where colors are: `black`, `red`, `green`, `yellow`, `blue`, `magenta`, `cyan`, `gray`, `brightblack`, `brightred`, `brightgreen`, `brightyellow`, `brightblue`, `brightmagenta`, `brightcyan`, `white`, or `default` For example, to set to the default colors: ```bash JC_COLORS=blue,brightblack,magenta,green ``` or ```bash JC_COLORS=default,default,default,default ``` ### Custom Parsers Custom local parser plugins may be placed in a `jc/jcparsers` folder in your local **"App data directory"**: - Linux/unix: `$HOME/.local/share/jc/jcparsers` - macOS: `$HOME/Library/Application Support/jc/jcparsers` - Windows: `$LOCALAPPDATA\jc\jc\jcparsers` Local parser plugins are standard python module files. Use the [`jc/parsers/foo.py`](https://github.com/kellyjonbrazil/jc/blob/master/jc/parsers/foo.py) parser as a template and simply place a `.py` file in the `jcparsers` subfolder. Local plugin filenames must be valid python module names, therefore must consist entirely of alphanumerics and start with a letter. Local plugins may override default plugins. > Note: The application data directory follows the [XDG Base Directory Specification](https://specifications.freedesktop.org/basedir-spec/basedir-spec-latest.html) ## Compatibility Some parsers like `ls`, `ps`, `dig`, etc. will work on any platform. Other parsers that are platform-specific will generate a warning message if they are used on an unsupported platform. To see all parser information, including compatibility, run `jc -ap`. You may still use a parser on an unsupported platform - for example, you may want to parse a file with linux `lsof` output on an OSX laptop. In that case you can suppress the warning message with the `-q` cli option or the `quiet=True` function parameter in `parse()`: ```bash cat lsof.out | jc --lsof -q ``` Tested on: - Centos 7.7 - Ubuntu 18.4 - Fedora32 - OSX 10.11.6 - OSX 10.14.6 - NixOS - FreeBSD12 ## Contributions Feel free to add/improve code or parsers! You can use the [`jc/parsers/foo.py`](https://github.com/kellyjonbrazil/jc/blob/master/jc/parsers/foo.py) parser as a template and submit your parser with a pull request. ## Acknowledgments - Local parser plugin feature contributed by [Dean Serenevy](https://github.com/duelafn) - CI automation and code optimizations by [philippeitis](https://github.com/philippeitis) - [`ifconfig-parser`](https://github.com/KnightWhoSayNi/ifconfig-parser) module by KnightWhoSayNi - [`xmltodict`](https://github.com/martinblech/xmltodict) module by Martín Blech - [`ruamel.yaml`](https://pypi.org/project/ruamel.yaml) module by Anthon van der Neut - Parsing [code](https://gist.github.com/cahna/43a1a3ff4d075bcd71f9d7120037a501) from Conor Heine adapted for some parsers - Excellent constructive feedback from [Ilya Sher](https://github.com/ilyash-b) ## Examples ### airport -I ```bash airport -I | jc --airport -p #
