> Check out the `jc` Python [package documentation](https://github.com/kellyjonbrazil/jc/tree/master/docs) for developers

> Try the `jc` [web demo](https://jc-web.onrender.com/)

> JC is [now available](https://galaxy.ansible.com/community/general) as an
Ansible filter plugin in the `community.general` collection. See this
[blog post](https://blog.kellybrazil.com/2020/08/30/parsing-command-output-in-ansible-with-jc/)
for an example.

# JC
JSON Convert

`jc` JSONifies the output of many CLI tools, file-types, and common strings
for easier parsing in scripts. See the [**Parsers**](#parsers) section for
supported commands, file-types, and strings.
```bash
dig example.com | jc --dig
```
```json
[{"id":38052,"opcode":"QUERY","status":"NOERROR","flags":["qr","rd","ra"],
"query_num":1,"answer_num":1,"authority_num":0,"additional_num":1,
"opt_pseudosection":{"edns":{"version":0,"flags":[],"udp":4096}},"question":
{"name":"example.com.","class":"IN","type":"A"},"answer":[{"name":
"example.com.","class":"IN","type":"A","ttl":39049,"data":"93.184.216.34"}],
"query_time":49,"server":"2600:1700:bab0:d40::1#53(2600:1700:bab0:d40::1)",
"when":"Fri Apr 16 16:09:00 PDT 2021","rcvd":56,"when_epoch":1618614540,
"when_epoch_utc":null}]
```

This allows further command-line processing of output with tools like `jq`
or [`jello`](https://github.com/kellyjonbrazil/jello) by piping commands:
```bash
$ dig example.com | jc --dig | jq -r '.[].answer[].data'
93.184.216.34
```

or using the alternative "magic" syntax:

```bash
$ jc dig example.com | jq -r '.[].answer[].data'
93.184.216.34
```

`jc` can also be used as a python library. In this case the output will be
a python dictionary, a list of dictionaries, or even a
[lazy iterable of dictionaries](#using-streaming-parsers-as-python-modules)
instead of JSON:
```python
>>> import subprocess
>>> import jc
>>>
>>> cmd_output = subprocess.check_output(['dig', 'example.com'], text=True)
>>> data = jc.parse('dig', cmd_output)
>>>
>>> data[0]['answer']
[{'name': 'example.com.', 'class': 'IN', 'type': 'A', 'ttl': 29658, 'data':
'93.184.216.34'}]
```

> For `jc` Python package documentation, use `help('jc')`, `help('jc.lib')`, or
see the [online documentation](https://github.com/kellyjonbrazil/jc/tree/master/docs).

Two representations of the data are available. 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()` when using `jc` as a python library.

Schemas for each parser can be found at the documentation link beside each
[**Parser**](#parsers) below.

### Binaries
For precompiled binaries, see [Releases](https://github.com/kellyjonbrazil/jc/releases)
on Github.

## Usage
`jc` accepts piped input from `STDIN` and outputs a JSON representation of the
previous command's output to `STDOUT`.
```bash
COMMAND | jc [OPTIONS] PARSER
cat FILE | jc [OPTIONS] PARSER
echo STRING | jc [OPTIONS] PARSER
```

Alternatively, the "magic" syntax can be used by prepending `jc` to the command
to be converted or in front of the absolute path for Proc files. Options can be
passed to `jc` immediately before the command or Proc file path is given.
(Note: command aliases and shell builtins are not supported)
```bash
jc [OPTIONS] COMMAND
jc [OPTIONS] /proc/<path-to-procfile>
```

The JSON output can be compact (default) or pretty formatted with the `-p`
option.

### Exit Codes
Any fatal errors within `jc` will generate an exit code of `100`, otherwise the
exit code will be `0`.

When using the "magic" syntax (e.g. `jc ifconfig eth0`),
`jc` will store the exit code of the program being parsed and add it to the `jc`
exit code. This way it is easier to determine if an error was from the parsed
program or `jc`.

Consider the following examples using `ifconfig`:

| `ifconfig` exit code | `jc` exit code | Combined exit code | Interpretation                     |
|----------------------|----------------|--------------------|------------------------------------|
| `0`                  | `0`            | `0`                | No errors                          |
| `1`                  | `0`            | `1`                | Error in  `ifconfig`               |
| `0`                  | `100`          | `100`              | Error in  `jc`                     |
| `1`                  | `100`          | `101`              | Error in  both `ifconfig` and `jc` |

When using the "magic" syntax you can also retrieve the exit code of the called
program by using the `--meta-out` or `-M` option. This will append a `_jc_meta`
object to the output that will include the magic command information, including
the exit code.

Here is an example with `ping`:
```bash
$ jc --meta-out -p ping -c2 192.168.1.252
{
  "destination_ip": "192.168.1.252",
  "data_bytes": 56,
  "pattern": null,
  "destination": "192.168.1.252",
  "packets_transmitted": 2,
  "packets_received": 0,
  "packet_loss_percent": 100.0,
  "duplicates": 0,
  "responses": [
    {
      "type": "timeout",
      "icmp_seq": 0,
      "duplicate": false
    }
  ],
  "_jc_meta": {
    "parser": "ping",
    "timestamp": 1661357115.27949,
    "magic_command": [
      "ping",
      "-c2",
      "192.168.1.252"
    ],
    "magic_command_exit": 2
  }
}
$ echo $?
2
```

### 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=<keyname_color>,<keyword_color>,<number_color>,<string_color>
```

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
```

### Disable Colors via Environment Variable
You can set the [`NO_COLOR`](http://no-color.org/) environment variable to any
value to disable color output in `jc`. Note that using the `-C` option to force
color output will override both the `NO_COLOR` environment variable and the `-m`
option.

### Streaming Parsers
Most parsers load all of the data from `STDIN`, parse it, then output the entire
JSON document serially. There are some streaming parsers (e.g. `ls-s` and
`ping-s`) that immediately start processing and outputing the data line-by-line
as [JSON Lines](https://jsonlines.org/) (aka [NDJSON](http://ndjson.org/)) while
it is being received from `STDIN`. This can significantly reduce the amount of
memory required to parse large amounts of command output (e.g. `ls -lR /`) and
can sometimes process the data more quickly. Streaming parsers have slightly
different behavior than standard parsers as outlined below.

> Note: Streaming parsers cannot be used with the "magic" syntax

#### Ignoring Errors

You may want to ignore parsing errors when using streaming parsers since these
may be used in long-lived processing pipelines and errors can break the pipe. To
ignore parsing errors, use the `-qq` cli option or the `ignore_exceptions=True`
argument with the `parse()` function. This will add a `_jc_meta` object to the
JSON output with a `success` attribute. If `success` is `true`, then there were
no issues parsing the line. If `success` is `false`, then a parsing issue was
found and `error` and `line` fields will be added to include a short error
description and the contents of the unparsable line, respectively:

Successfully parsed line with `-qq` option:
```json
{
  "command_data": "data",
  "_jc_meta": {
    "success": true
  }
}
```

Unsuccessfully parsed line with `-qq` option:
```json
{
  "_jc_meta": {
    "success": false,
    "error": "error message",
    "line": "original line data"
  }
}
```

#### Unbuffering Output

Most operating systems will buffer output that is being piped from process to
process. The buffer is usually around 4KB. When viewing the output in the
terminal the OS buffer is not engaged so output is immediately displayed on the
screen. When piping multiple processes together, though, it may seem as if the
output is hanging when the input data is very slow (e.g. `ping`):
```
$ ping 1.1.1.1 | jc --ping-s | jq
<slow output>
```

This is because the OS engages the 4KB buffer between `jc` and `jq` in this
example. To display the data on the terminal in realtime, you can disable the
buffer with the `-u` (unbuffer) cli option:
```
$ ping 1.1.1.1 | jc --ping-s -u | jq
{"type":"reply","pattern":null,"timestamp":null,"bytes":"64","respons...}
{"type":"reply","pattern":null,"timestamp":null,"bytes":"64","respons...}
...
```

> Note: Unbuffered output can be slower for large data streams.

#### Using Streaming Parsers as Python Modules

Streaming parsers accept any iterable object and return an iterable object
allowing lazy processing of the data. The input data should iterate on lines
of string data. Examples of good input data are `sys.stdin` or
`str.splitlines()`.

To use the returned iterable object in your code, simply loop through it or
use the [next()](https://docs.python.org/3/library/functions.html#next)
builtin function:
```python
import jc

result = jc.parse('ls_s', ls_command_output.splitlines())
for item in result:
    print(item["filename"])
```

### 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)
or [`jc/parsers/foo_s.py (streaming)`](https://github.com/kellyjonbrazil/jc/blob/master/jc/parsers/foo_s.py)
parser as a template and simply place a `.py` file in the `jcparsers` subfolder.

Local plugin filenames must be valid python module names and therefore must
start with a letter and consist entirely of alphanumerics and underscores.
Local plugins may override default parsers.

> Note: The application data directory follows the
[XDG Base Directory Specification](https://specifications.freedesktop.org/basedir-spec/basedir-spec-latest.html)

### Caveats

#### Locale

For best results set the locale environment variables to `C` or
`en_US.UTF-8` by modifying the `LC_ALL` variable:
```
$ LC_ALL=C date | jc --date
```

You can also set the locale variables individually:
```
$ export LANG=C
$ export LC_NUMERIC=C
```

On some older systems UTF-8 output will be downgraded to ASCII with `\\u`
escape sequences if the `C` locale does not support UTF-8 encoding.

#### Timezones

Some parsers have calculated epoch timestamp fields added to the output. Unless
a timestamp field name has a `_utc` suffix it is considered naive. (i.e. based
on the local timezone of the system the `jc` parser was run on).

If a UTC timezone can be detected in the text of the command output, the
timestamp will be timezone aware and have a `_utc` suffix on the key name.
(e.g. `epoch_utc`) No other timezones are supported for aware timestamps.

## Use In Other Shells
`jc` can be used in most any shell. Some modern shells have JSON deserialization
and filtering capabilities built-in which makes using `jc` even more convenient.

For example, the following is possible in [NGS](https://ngs-lang.org/)
(Next Generation Shell):
```bash
myvar = ``jc dig www.google.com``[0].answer[0].data
```
This runs `jc`, parses the output JSON, and assigs the resulting data structure
to a variable in a single line of code.

For more examples of how to use `jc` in other shells, see this
[wiki page](https://github.com/kellyjonbrazil/jc/wiki/Using-jc-With-Different-Shells).

## Compatibility
Some parsers like `dig`, `xml`, `csv`, etc. will work on any platform. Other
parsers that convert platform-specific output will generate a warning message if
they are run 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 macOS or Windows laptop. In
that case you can suppress the warning message with the `-q` cli option or the
`quiet=True` function parameter in `parse()`:

macOS:
```bash
cat lsof.out | jc -q --lsof
```

or Windows:
```bash
type lsof.out | jc -q --lsof
```

Tested on:
- Centos 7.7
- Ubuntu 18.04
- Ubuntu 20.04
- Fedora32
- macOS 10.11.6
- macOS 10.14.6
- NixOS
- FreeBSD12
- Windows 10
- Windows 2016 Server
