barista =============================================================================== ![screenshot](screenshot.png) [![test status](https://github.com/xandkar/barista/actions/workflows/test.yml/badge.svg)](https://github.com/xandkar/barista/actions) [![dependencies status](https://deps.rs/repo/github/xandkar/barista/status.svg)](https://deps.rs/repo/github/xandkar/barista) [pista](https://github.com/xandkar/pista)'s more featureful successor. Intended for use with [dwm](https://dwm.suckless.org/), but can just as well be adopted to anything else with a textual status area (like [tmux](https://github.com/tmux/)). Runs N shell commands (specified in configuration file), asynchronously reads lines from them and routes to N corresponding slots on the bar: b +--------------+--------------+- ... ---+-------------+ a | slot_1 | slot_2 | | slot_N | r +--------------+--------------+- ... ---+-------------+ ^ ^ ^ | | | +-+ +-+ +-+ | | | | | | |S| |S| |S| |T| |T| |T| |D| |D| |D| |O| |O| |O| |U| |U| |U| |T| |T| |T| | | | | | | |1| |2| |N| | | | | | | +-+ +-+ +-+ ^ ^ ^ | | | command_1 command_2 ... command_N | | | v v v +-+ +-+ +-+ | | | | | | |S| |S| |S| |T| |T| |T| |D| |D| |D| |E| |E| |E| |R| |R| |R| |R| |R| |R| | | | | | | |1| |2| |N| | | | | | | +-+ +-+ +-+ | | | v v v l +--------+ +--------+ ... +--------+ o | file_1 | | file_2 | | file_N | g +--------+ +--------+ ... +--------+ Each slot is given a TTL, after which, if there was no update, the slot is cleared - helping you spot broken commands and not fool yourself with stale data. Each command's `stderr` is redirected to `~/.barista/feeds/$i-$name/log`. Install ------------------------------------------------------------------------------- 1. `cargo install barista` 2. Ensure `~/.cargo/bin/` is in your `PATH` 3. `barista help` Use ------------------------------------------------------------------------------- ### Initial 1. In terminal A, run `barista server`, which will create `~/.barista/` directory and initialize default configuration 2. In terminal B, edit configuration file to your liking: `~/.barista/conf.toml` 3. In terminal B, run `barista reload` 4. See `barista help` for more functionality ### Normal Normally you'd run `barista server &` from `~/.xinitrc` (or similar). This will run the commands you specified in config and set the bar at intervals you specified in config. While the barista server is running, you can ask it for changes and status from any other terminal (they communicate via a Unix domain socket: `~/.barista/socket`): 1. `barista reload` to reload configuration after changing it at runtime 2. `barista status` to see how each command is doing (last update, etc) 3. `barista off` to stop the commands and clear the bar 4. `barista on` to start the commands and start updating the bar Examples ------------------------------------------------------------------------------- ### Status Yo Dawg, we heard you like status, so you can now check status of your status[^1]: ```sh $ barista status POSITION NAME DIR LAST_OUTPUTTED LAST_LOGGED LOG_SIZE LOG_LINES PID PROC_STATE PROC_DESCENDANTS 1 upower /home/xand/.barista/feeds/00-upower 7s 3h 48m 35s 565.3 KB 6880 17424 S 17451:Z,17452:S 2 eth /home/xand/.barista/feeds/01-eth 0s 8days 18h 37m 30s 4.1 MB 39819 17425 S - 3 wifi /home/xand/.barista/feeds/02-wifi 0s 8days 18h 37m 30s 4.1 MB 40508 17426 S - 4 bluetooth /home/xand/.barista/feeds/03-bluetooth 0s 8days 18h 37m 30s 4.1 MB 39537 17427 S - 5 memory /home/xand/.barista/feeds/04-memory 0s 8days 18h 37m 30s 8.2 MB 78508 17428 S - 6 disk /home/xand/.barista/feeds/05-disk 3s 8days 18h 37m 30s 1.7 MB 16210 17429 S - 7 backlight /home/xand/.barista/feeds/06-backlight 4days 23h 20m 21s 8days 18h 37m 30s 39.0 KB 608 17430 S - 8 pulseaudio /home/xand/.barista/feeds/07-pulseaudio 9m 16s 8days 18h 37m 30s 185.9 KB 2114 17431 S 17461:S 9 mpd /home/xand/.barista/feeds/08-mpd 0s 8days 18h 37m 30s 7.9 MB 76463 17432 S - 10 weather /home/xand/.barista/feeds/09-weather 15m 30s 35m 30s 185.5 KB 3146 17433 S - 11 time /home/xand/.barista/feeds/10-time 0s 8days 18h 37m 30s 10.6 MB 78515 17434 S - 12 keymap /home/xand/.barista/feeds/11-keymap 0s 8days 18h 37m 30s 8.2 MB 78491 17436 S - ``` Footnotes ------------------------------------------------------------------------------- [^1]:
