# Contributing to jc
We love your input! We want to make contributing to this project as easy and transparent as possible, whether it's:
- Reporting a bug
- Discussing the current state of the code
- Submitting a fix
- Proposing new features
- Proposing a new parser
## We Develop with Github
We use github to host code, to track issues and feature requests, as well as accept pull requests.
## We Use Github Flow, So All Code Changes Happen Through Pull Requests
Pull requests are the best way to propose changes to the codebase (we use [Github Flow](https://guides.github.com/introduction/flow/index.html)). We actively welcome your pull requests:
1. Open an issue to discuss the new feature, bug fix, or parser before opening a pull request. For new parsers, it is important to agree upon a schema before developing the parser.
2. Fork the repo and create your branch from `dev`, if available, otherwise `master`.
3. If you've added code that should be tested, add tests. All new parsers should have several sample outputs and tests.
4. Documentation is auto-generated from docstrings, so ensure they are clear and accurate.
5. Ensure the test suite passes.
6. Make sure your code lints.
7. Issue that pull request!
## Parser Schema Guidelines
- Try to keep the schema as flat as possible - typically a list of flat dictionaries
- Keys should be lowercase, contain no special characters, and spaces should be converted to underscores
- Keys should be static, if possible. If they have to be dynamic, then they should not contain lists or dictionaries
This will make it easier to use tools like `jq` without requiring escaping of special characters, encapsulating key names in [""], keeps paths predictable, and makes iterating and searching for values easier.
**Examples**
Bad:
```
{
"Interface 1": [
192.168.1.1,
172.16.1.1
],
"Wifi Interface 1": [
10.1.1.1
]
}
```
Good:
```
[
{
"interface": "Interface 1",
"ip_addresses": [
192.168.1.1,
172.16.1.1
]
},
{
"interface": "Wifi Interface 1",
"ip_addresses": [
10.1.1.1
]
}
]
```
## Any contributions you make will be under the MIT Software License
In short, when you submit code changes, your submissions are understood to be under the same [MIT License](http://choosealicense.com/licenses/mit/) that covers the project. Feel free to contact the maintainers if that's a concern.
## Report bugs using Github's Issues
We use GitHub issues to track public bugs. Report a bug by [opening a new issue](https://github.com/kellyjonbrazil/jc/issues); it's that easy!
## Write bug reports with detail, background, and sample code
**Great Bug Reports** tend to have:
- A quick summary and/or background
- Steps to reproduce
- Be specific!
- Give sample code if you can.
- What you expected would happen
- What actually happens
- Notes (possibly including why you think this might be happening, or stuff you tried that didn't work)
## Use a Consistent Coding Style
* 4 spaces for indentation rather than tabs
* Use a Python linter that will enforce PEP 8 and other best practices

```
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.
> Note: 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.
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.
Schemas for each parser can be found at the documentation link beside each parser below.

## 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()`:

jc - JSON CLI output utility `ls` and `vdir` command output parser
Options supported:
- `lbaR`
- `lbaR1`
- `--time-style=full-iso`
- `-h`: File sizes will be available in text form with `-r` but larger file sizes with human readable suffixes will be converted to `Null` in the default view since the parser attempts to convert this field to an integer.
Note: The `-l` or `-b` option of `ls` should be used to correctly parse filenames that include newline characters. Since `ls` does not encode newlines in filenames when outputting to a pipe it will cause `jc` to see multiple files instead of a single file if `-l` or `-b` is not used. Alternatively, `vdir` can be used, which is the same as running `ls -lb`.

# jc.parsers.time
jc - JSON CLI output utility `/usr/bin/time` command output parser
Output from `/usr/bin/time` is sent to `STDERR`, so the `-o` option can be used to redirect the output to a file that can be read by `jc`.
Alternatively, the output from `/usr/bin/time` can be redirected to `STDOUT` so `jc` can receive it.
Note: `/usr/bin/time` is similar but different from the Bash builtin `time` command.
Usage (cli):
$ /usr/bin/time -o timefile.out sleep 2.5; cat timefile.out | jc --time -p
Usage (module):
import jc.parsers.time
result = jc.parsers.time.parse(time_command_output)
Compatibility:

"""jc - JSON CLI output utility `rpm -qi` command output parser
Works with `rpm -qi [package]` or `rpm -qia`.
The `build_epoch` calculated timestamp field is naive (i.e. based on the local time of the system the parser is run on)
The `build_epoch_utc` calculated timestamp field is timezone-aware and is only available if the timezone field is UTC.
Usage (cli):
$ rpm -qia | jc --rpm_qi
or
$ jc rpm -qia
Usage (module):
import jc.parsers.rpm_qi
result = jc.parsers.rpm_qi.parse(rpm_qi_command_output)
Compatibility:
'linux'
Examples:
$ rpm -qia | jc --rpm_qi -p

"""jc - JSON CLI output utility `/usr/bin/time` command output parser
Output from `/usr/bin/time` is sent to `STDERR`, so the `-o` option can be used to redirect the output to a file that can be read by `jc`.

Note: `/usr/bin/time` is similar but different from the Bash builtin `time` command.

.SH DESCRIPTION
jc JSONifies the output of many CLI tools and file-types for easier parsing in scripts. jc accepts piped input from STDIN and outputs a JSON representation of the previous command's output to STDOUT. 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).

.SH ENVIRONMENT
You can specify custom colors via the \fBJC_COLORS\fP environment variable. The \fBJC_COLORS\fP environment variable takes four comma separated string values in the following format:
JC_COLORS=<keyname_color>,<keyword_color>,<number_color>,<string_color>
Where colors are: \fBblack\fP, \fBred\fP, \fBgreen\fP, \fByellow\fP, \fBblue\fP, \fBmagenta\fP, \fBcyan\fP, \fBgray\fP, \fBbrightblack\fP, \fBbrightred\fP, \fBbrightgreen\fP, \fBbrightyellow\fP, \fBbrightblue\fP, \fBbrightmagenta\fP, \fBbrightcyan\fP, \fBwhite\fP, or \fBdefault\fP
For example, to set to the default colors:
.RS
.PP
JC_COLORS=blue,brightblack,magenta,green
or
JC_COLORS=default,default,default,default
.RE
.SH CUSTOM PARSERS
Custom local parser plugins may be placed in a \fBjc/jcparsers\fP folder in your local "App data directory":
.RS
- Linux/unix: \fB$HOME/.local/share/jc/jcparsers\fP
- macOS: \fB$HOME/Library/Application Support/jc/jcparsers\fP
- Windows: \fB$LOCALAPPDATA\\jc\\jc\\jcparsers\fP
.RE
Local parser plugins are standard python module files. Use the \fBjc/parsers/foo.py\fP parser as a template and simply place a \fB.py\fP file in the \fBjcparsers\fP 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
.SH EXAMPLE
ls \fB-al\fP | jc \fB--ls\fP \fB-p\fP
