# FILE: dimswitch
|
||
# USAGE: dimswitch [-v] [-h] [-i [application]] [-t theme name] dark/light
|
||
#
|
||
# DESCRIPTION:
|
||
# Toggle alacritty terminal, and between dark
|
||
# or light mode (if correctly set up in the alacritty.yml file), see REQUIREMENTS
|
||
# The default action is to toggle between light and dark mode.
|
||
#
|
||
# OPTIONS: see function ’usage’ below
|
||
#
|
||
# REQUIREMENTS:
|
||
# The alacritty.yml file needs to have the various color-schemes set up as yaml
|
||
# anchors. The script itself will then switch the referenced anchor in the actual
|
||
# `color` key of the file. For an example alacritty.yml refer to its wiki, or
|
||
# this file: https://gitlab.com/marty-oehme/dotfiles/blob/master/.config/alacritty/alacritty.yml
|
||
#
|
||
# NOTES: This script is in active development and its functionality and options
|
||
# are very much undergoing changes. For now, do not rely on its options
|
||
# staying stable.
