Bash prompt themes, with a color gradient feature.
Themes are a combination of a template and a color palette. The template is the prompt itself and the colors from the palette are applied onto it.
Theme names are a combinasion of their template and palette: template_palette like teal_horizon.
Demo all the themes using:
./demo_themes
To use a theme simply source it to your current shell:
source ./themes/teal_horizonClone the repo on your machine because themes aren't fully standalone, they use the lib/lib file from this repo.
Source the theme in your .bashrc. For instance, at the end of your .bashrc, add:
# Change the path with where you put bash-ps1-themes
source ~/bash-ps1-themes/themes/teal_cyber_3The themes work with the PROMPT_COMMAND and PS1 environment variable.
The PROMPT_COMMAND invokes a function that in turn invokes other functions to build a PS1 variable.
You can create your own templates and color palettes.
Create a new file in the palettes/ folder and update the following variables to your liking:
#!/bin/bash
palette_primary="#1bcfc6"
palette_primary_dark="#02a199"
palette_secondary="#008cff"
palette_secondary_dark="#0066ba"
palette_accent="#b88914"
palette_accent_dark="#9c7f0c"
palette_gradient_start="#0bb092"
palette_gradient_end="#008cff"
palette_variant_1="#00d7af"
palette_variant_2="#00d7d7"
palette_variant_3="#00d7ff"
palette_text="#d2d2d2"To preview the palette in the terminal, use:
./demo_palettes
./demo_palettes --detailed
Create a new file in the templates/ folder.
This snippet is an example of a basic template:
#!/bin/bash
scriptDir=$(dirname -- "$(readlink -f -- "$BASH_SOURCE")")
source $scriptDir'/../lib/lib'
prompt_cmd() {
LINE_1="$(rgb_fg_ps1 $palette_primary)$(current_user) $(rgb_fg_ps1 $palette_secondary)$(basename $PWD)"
LINE_2="$(rgb_fg_ps1 $palette_accent)$ $(rgb_fg_ps1 $palette_text)"
PS1="\r\n${LINE_1}\r\n${LINE_2}"
}
export PROMPT_COMMAND='prompt_cmd'Here are some functions you can use in your templates:
# Set the foreground color, all text set after calling this function will be the desired color
rgb_fg_ps1 "#ffffff"
# Set the background color, all text set after calling this function will be the desired color
rgb_bg_ps1 "#ffffff"
# Create a foreground gradient over a defined string
fg_gradient_ps1 "#ff0000" "#00ff00" "some string to receive gradient"
# Create a background gradient over a defined string
bg_gradient_ps1 "#ff0000" "#00ff00" "some string to receive gradient"
# Current git branch
gitbranchSee the lib/ source for more functions.
Then, to apply the palette to the templates, there is a generate_themes script that combines all sets of templates and palettes together:
./generate_themesYour theme will be generated in the themes/ folder.
Works only in Bash shells.
