# Simple colored bash prompt

Defined in `/etc/profile.d/bash-color-prompt.sh`

The prompt color theme can be customized simply by setting
the `PROMPT_COLOR` envvar, and optionally `PROMPT_DIR_COLOR`.

For example `PROMPT_COLOR='2;7'` is dim inverse-video
and `PROMPT_COLOR='1;33;53'` is bright/bold yellow with overline.

`PROMPT_DIR_COLOR` similarly changes the color of the working directory,
which otherwise defaults to `PROMPT_COLOR`.

## Coloring Examples

```shell
PROMPT_COLOR=0 # disable colors/attribs
PROMPT_COLOR=1 # bold prompt
PROMPT_COLOR=2 # dim prompt
PROMPT_COLOR=4 # underline prompt
PROMPT_COLOR='2;7' # dim reverse video
PROMPT_COLOR='42' # green background
PROMPT_COLOR='53' # overline separator
PROMPT_COLOR='1;33;44' # bold yellow on blue
PROMPT_COLOR='43;30' # black on yellow
PROMPT_COLOR='1;32' # bold green
PROMPT_COLOR='' # unset defaults to green
```

```shell
eval $(grep ANSI_COLOR /etc/os-release)
PROMPT_COLOR="$ANSI_COLOR"
```

## More variables

### `PROMPT_START` (optional)
Displayed at the start of the prompt.

### `PROMPT_SEPARATOR`
Default: `PROMPT_SEPARATOR=':'`

eg you can change it to `'\n` or `' \t\n'

### `PROMPT_DIRECTORY`
Default: `PROMPT_DIRECTORY='\w'`

eg you can change it to `'\W'`

### `PROMPT_ERROR`
Set (eg `PROMPT_ERROR=1`) if you want to append red error exit code to
the prompt.

### `PROMPT_END`
Displayed at the end of the prompt (before `\$`).

## Traditional Red Hat prompt
```
PROMPT_START='['
PROMPT_END=']'
PROMPT_SEPARATOR=' '
PROMPT_DIRECTORY='\W'
PROMPT_COLOR='0'
```

## Defaults functions
The traditional Red Hat prompt can be set with the `prompt_traditional` function.

The prompt can be reset to default with the `prompt_default` function.

Use the `prompt_default_os` function to use `ANSI_COLOR` from `/etc/os-release`.

## Sourcing
Set `prompt_color_force` (before source'ing) to force usage/updating of color
PS1: by default it is only setup cautiously if `$TERM` ends in "color"
*and* PS1 is the fedora or bash default.

```shellsession
$ prompt_color_force=1
$ source /etc/profile.d/bash-color-prompt.sh
```
