Features:

* Zero dependencies. You don't need to install additional packages.

* Clear concept. The bar is a delimiter and information panel. Three attention aspects: command line and path, output, sections with additional info.

* The command beginning has fixed position to have a large command line every time and avoid mess of attention.

* The sections placed to right but not in the same line as command and it allows you to copy the command and output without environmental disclosure.

* Full customization. Change colors, add sections with info you need easily with Python.

## Install

```python

xpip install -U xontrib-prompt-bar

echo 'xontrib load prompt_bar' >> ~/.xonshrc

# Reload xonsh

```

## Default theme

```python

$XONTRIB_PROMPT_BAR_THEME = {

    'left': '{hostname}{user}{cwd_abs#accent}',

    'right': '{hist_status#section}{curr_branch#section}{env_name#strip_brackets#section}{date_time_tz}',

    'bar_bg': '{BACKGROUND_#323232}',

    'bar_fg': '{#AAA}',

    'section_bg': '{BACKGROUND_#444}',

    'section_fg': '{#CCC}',

    'accent_fg': '{BOLD_#DDD}',

}

xontrib load prompt_bar

```

## Use cases

### Customize the fields

Supported fields:

* [xonsh default fields and colors notation](https://xon.sh/tutorial.html#customizing-the-prompt)

* `screens` - list of the windows that created by [screen window manager](https://www.gnu.org/software/screen/manual/screen.html#Overview) i.e. `screen -S mywin`.

* `cwd_abs` - current absolute path (`~` disabled).

* `date_time_tz` - date and time with timezone i.e. `21-12-25 18:00:00-01`.

* `hist_status` - show `hist off` if history disabled by [`history off`](https://xon.sh/tutorial_hist.html#off-action) command.

To customize the appearance of the fields on the bar you can use wrappers and chaining them:

```python

$XONTRIB_PROMPT_BAR_RIGHT = '{hostname#accent#section} {date_time_tz#nocolorx}'

xontrib load prompt_bar

```

Builtin wrappers:

* `section` - add backlight for the text.

* `accent` - bold font and lighter color.

* `noesc` - remove the ANSI escape characters (colors).

* `strip` - remove the white spaces in the begin and end.

* `strip_brackets` - remove the white spaces in the begin and end and then remove the brackets `()[]{}` if the text begins from brackets.

* `nonl` - replace the new line symbols to spaces.

* `nocolorx` - remove the xonsh color tags i.e. `{RED}` or `{#00ff00}`.

To create your own fields and wrapper see the section below.

### Add custom fields and wrappers

How to add two new fields called `my_left_custom` and `my_right_custom` and one new wrapper called `brackets`.

```python

$PROMPT_FIELDS['my_left_custom'] = 'Hello left!'

$PROMPT_FIELDS['my_right_custom'] = lambda: '>'*3 + ' {YELLOW}Hello right!'

$XONTRIB_PROMPT_BAR_WRAPPERS = {

    'brackets': lambda v: f'[{v}]'

}

$XONTRIB_PROMPT_BAR_LEFT = '{hostname}{user}{cwd_abs#accent}{my_left_custom#brackets}'

$XONTRIB_PROMPT_BAR_RIGHT = '{my_right_custom#section}{env_name#strip_brackets#section}{date_time_tz}'

xontrib load prompt_bar

```

Result:



### Themes and colors

To change the bar colors there is setting the theme:

```python

$XONTRIB_PROMPT_BAR_THEME = {

    'left':       '{hostname}{user}{cwd_abs#accent}',

    'right':      '{curr_branch#section}{env_name#strip_brackets#section}{date_time_tz}',

    'bar_bg':     '{BACKGROUND_#FF0000}',

    'bar_fg':     '{#AAA}',

    'section_bg': '{BACKGROUND_#444}',

    'section_fg': '{#CCC}',

    'accent_fg':  '{BOLD_#DDD}',

}

xontrib load prompt_bar

```

To choose the colors there is [HTML Color Picker](https://www.w3schools.com/colors/colors_picker.asp).

### Using [Starship](https://github.com/starship/starship) cross-shell prompt to rendering right sections

"Barship" using [xontrib-prompt-starship](https://github.com/anki-code/xontrib-prompt-starship):

```python

# First of all create a starship config to return sections in one line

mkdir -p ~/.config && echo @("""

[character]

success_symbol = ""

error_symbol = ""

[status]

symbol = ""

""".strip()) > ~/.config/starship_xonsh_right.toml

# Then just add the starship bar to right

$XONTRIB_PROMPT_STARSHIP_RIGHT_CONFIG = "~/.config/starship_xonsh_right.toml"

$XONTRIB_PROMPT_STARSHIP_REPLACE_PROMPT = False

$XONTRIB_PROMPT_BAR_RIGHT = '{starship_right#noesc#nonl#strip}'

xontrib load prompt_starship prompt_bar

```

Result:



### Using [xontrib-cmd-durations](https://github.com/jnoortheen/xontrib-cmd-durations)

The [xontrib-cmd-durations](https://github.com/jnoortheen/xontrib-cmd-durations) is to send notification once long-running command is finished and also show the execution time. Usage example:

```python

# Add `{long_cmd_duration}` section

$XONTRIB_PROMPT_BAR_RIGHT = '{long_cmd_duration}{curr_branch#section}{screens#section}{env_name#strip_brackets#section}{date_time_tz}'

xontrib load cmd_done

```

### Hide return code in special cases

Sometimes it's needed to hide the return code. In this case you can use `-8888` return code i.e.:

```xsh

aliases['cdls'] = "cd @($arg0) && @(lambda: -8888 if len(g`./*`) > 100 else 0) && ls --group-directories-first -A --color"

cdls /

# return code is 0 and `ls` command was executed and return code is not shown

cdls /usr/sbin

# return code is -8888 and `ls` command was NOT executed and return code is not shown

```
