ado

ado is a terminal emulator for Wayland, written in Zig.

Building

Dependencies:

• zig master, see minimum_zig_version in build.zig.zon
• pkg-config
• wayland, xkbcommon and fcft
• tic from ncurses, for the terminfo entry

Then install ado and its terminfo entry, for example:

zig build -Doptimize=ReleaseFast --prefix ~/.local install
tic -x -e ado,ado-direct -o ~/.terminfo terminfo/ado.info

Terminfo

ado sets TERM=ado, so its terminfo entry must be installed on every machine you run it on. Without it, programs fall back to a dumb terminal: less warns "terminal is not fully functional" and leaves the screen in a bad state, and full-screen programs misbehave. ado checks for the entry when it starts and prints a warning in the window if it is missing.

For your user only:

tic -x -e ado,ado-direct -o ~/.terminfo terminfo/ado.info

System-wide, as root:

zig build install-terminfo --prefix /usr

ncurses only looks in ~/.terminfo and /usr/share/terminfo by default, so installing it with --prefix ~/.local puts it where nothing finds it.

Hosts you ssh into need the entry too. To copy it over:

infocmp -x ado | ssh host 'tic -x -o ~/.terminfo -'

Configuration

ado reads ~/.config/ado/ado.ini, or the file given with -c. For example:

[main]
font=monospace:size=12
font-fallback=Noto Color Emoji
blink-cursor = no

[colors]
alpha=0.9

ado --help lists the command-line options.
