paleta
________________________________________________________________________________
Change terminal colors on-the-fly independent of terminal emulator.
Most terminal emulators support a set of escape sequences which allow for the
modification of the terminal's color palette. Combined with the ability to write
to all open terminal devices, this allows for theming in a truly independent way.
Paleta reads a list of colors over <stdin>, transforms the input into the set of
escape sequences and sends these sequences to every open terminal in the system.
It additionally prints the sequences to <stdout>.

This tool is small and generic. It reads input and writes output. Effortless to
incorporate with the system. This repository also contains 150~ popular palettes
ready for use with paleta.

usage
________________________________________________________________________________
+------------------------------------------------------------------------------+
| |
| 1. Set the colorscheme to jellybeans-dark in all open terminals. |
| |
| $ paleta < palettes/jellybeans-dark > ~/.cache/current-palette |
| |
+------------------------------------------------------------------------------+
Saving paleta's <stdout> to a file is how the current palette is stored. This
file is used to set the palette in newly opened terminals. Scripts might instead
store this in a variable or ignore it entirely as they maintain state.
setup
________________________________________________________________________________
This line must be added to $SHELL's startup file. It tells future terminals to
load the current palette at launch.
+------------------------------------------------------------------------------+
| |
| $ echo 'cat ~/.cache/current-palette' >> ~/.bashrc |
| |
+------------------------------------------------------------------------------+
input format
________________________________________________________________________________
Input is one hex color per line, without #. The first three lines are
reserved for <foreground>, <background> and <cursor> with the remaining lines
filling the numerical palette (0-256).
Example: https://github.com/dylanaraps/paleta/blob/master/palettes/gruvbox-dark
+------------------------------------------------------------------------------+
| format | example |
+-------------------------------------+----------------------------------------+
| | |
| <foreground> | dedede |
| <background> | 121212 |
| <cursor> | dedede |
| <color0> | 929292 |
| <color1> | e27373 |
| <color2> | 94b979 |
| | |
| ... | ,,, |
| | |
| <color256> | 1ab2a8 |
| | |
| | |
+-------------------------------------+----------------------------------------+
The maximum palette is (3 + 256). This is configurable at compile-time.
