^{Screenshot made in Konsole with $XONSH_COLOR_STYLE = "paraiso-dark".}

If you like the idea of bar theme click ⭐ on the repo and stay tuned.

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

xpip install -U xontrib-prompt-bar
echo 'xontrib load prompt_bar' >> ~/.xonshrc
# Reload xonsh

Use cases

Fields

The bar theme supports fields:

• xonsh default fields and colors notation
• screens - list of the windows that created by screen window manager
• cwd_abs - current absolute path (~ disabled)
• date_time_tz - date and time with timezone i.e. 21-12-25 18:00:00-01
• gitstatus_noc - the same as xonsh gitstatus but without colors

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

$XONTRIB_PROMPT_BAR_RIGHT = '{hostname#accent#section}'
xontrib load prompt_bar

Available wrappers:

• section - add backlight for the text
• accent - bold font and lighter color
• noesc - remove ANSI escape characters (colors)
• strip - remove white spaces in the begin and end
• nonl - replace new line symbols to spaces
• nocolorx - remove xonsh color tags i.e. {RED} or {#00ff00}
• Also you can 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.

$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#section}{gitstatus_noc#section}{date_time_tz}'

xontrib load prompt_bar

Result:

Themes and colors

To change the bar colors there is setting the theme:

$XONTRIB_PROMPT_BAR_THEME = {
    'left':       '{hostname}{user}{cwd_abs#accent}',
    'right':      '{env_name#section}{gitstatus_noc#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

Using Starship cross-shell prompt to rendering right sections

Barship using xontrib-prompt-starship:

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