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 , 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 .

See src/config.h for configuration.

+------------------------------------------------------------------------------+ | | | Using make (recommended) | | | | $ make | | $ make install | | | | | | Invoking the compiler directly | | | | $ c99 $CFLAGS -o paleta src/paleta.c | | | | | +------------------------------------------------------------------------------+

usage

Set the colorscheme to jellybeans-dark in all open terminals. | | | | $ paleta < palettes/jellybeans-dark > ~/.cache/current-palette | | | +------------------------------------------------------------------------------+

Saving paleta's 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 , and with the remaining lines filling the numerical palette (0-256).

The maximum palette is (3 + 256). This is configurable at compile-time.
