ChromaTerm (`ct`) is a Python script that colors your output to terminal using
regular expressions. It works with interactive programs, like SSH.

## Installation

```shell
pip3 install chromaterm
```

## Usage

Think of `ct` like `grep`; just pipe data into it, like `ssh somewhere | ct`.

```shell
echo "Jul 14 12:28:19  Message from 1.2.3.4: Completed successfully" | ct
```

If you want to always highlight a program, you can set up a function in your
`.bash_profile`. For instance, here's one for `ssh`:
```shell
ssh() { /usr/bin/ssh "$@" | ct; }
```

Some programs behave differently when piped, like `less`. In that case, `ct` can
hide the pipe by spawning your program. You just have to prefix the command with
`ct`, like `ct less file.txt`.

## Highlight Rules

ChromaTerm reads highlight rules from a YAML configuration file, formatted like so:

```yaml
rules:
- description: My first rule colors the foreground
  regex: hello.+world
  color: f#ff0000

- description: Make "there" bold and italic. Paint "buddy" red
  regex: Hey (there), (buddy)
  color:
    1: bold italic
    2: b#ff0000
```

ChromaTerm will look in the following locations for the config file and use the
first one it finds:

 * `$HOME/.chromaterm.yml`
 * `$XDG_CONFIG_HOME/chromaterm/chromaterm.yml` (if `$XDG_CONFIG_HOME` is not set,
 it defaults to `~/config`)
 * `/etc/chromaterm/chromaterm.yml`

If no file is found, a default one is created in your home directory.

> Check out [`contrib/rules`](https://github.com/hSaria/ChromaTerm/tree/master/contrib/rules);
> it has some topic-specific rules that are not included in the defaults.

### Description

Optional. It's purely for your sake.

### RegEx

The RegEx engine used is Python's [re](https://docs.python.org/3/library/re.html).

### Color

#### Background and Foreground

The color is a hex string prefixed by `b` for background (e.g. `b#123456`) and
`f` for foreground (e.g. `f#abcdef`).

#### Style

In addition to the background and foreground, the following styles are supported,
though some terminals ignore them:

 * Blink
 * Bold
 * Italic
 * Strike
 * Underline

### Group

A color can be applied per RegEx group (see the 2nd example rule). Any group in
the regular expression can be referenced.

## Help

If you've got any questions or suggestions, please open up an
[issue](https://github.com/hSaria/ChromaTerm/issues/new/choose) (always
appreciated).

### Windows support

To use ChromaTerm on Windows, you will need to run it with the
[Windows Subsystem for Linux (`WSL`)](https://docs.microsoft.com/en-us/windows/wsl/about)
