goobar is a status line generator similar in spirit to
i3status(1). The main difference is
that goobar is written in GNU Guile and
highly extensible.
It consists of two distinct parts: a set of status collectors, and a program that converts their results to a format that can be consumed by window managers such as Sway or i3.
Goobar has no dependencies apart from Guile itself. For extra functionality, consider installing:
- Guile-Netlink for Ethernet and WiFi information.
- Guile-GnuTLS for HTTP-based status collectors.
- Guile-SRFI-180 for status collectors that consume JSON.
- PulseAudio for PulseAudio information.
From a source checkout, run:
$ autoreconf -vif
$ ./configure && make -j $(nproc)
# At this stage, you can run the program as:
$ ./pre-inst-env goobar
# Or install it:
$ sudo make install
If you have GNU Guix on your system, you can install
goobar with e.g. guix package -p /tmp/goobar -f guix.scm and then run it as
/tmp/goobar/bin/goobar.
By default, the output is similar to that of i3status:
$ goobar
IPv6: ❌ | 🖴 81% | 📶 Home Wifi (68%, 144.4 Mb/s) | E: down | 🔋 75.62% 06:35 | 🔊 99% | 🏋️ 0.40 | 🌡️46°C | 6.7 GiB | 2023-06-26 20:49:05
IPv6: ❌ | 🖴 81% | 📶 Home Wifi (69%, 144.4 Mb/s) | E: down | 🔋 75.55% 06:31 | 🔊 99% | 🏋️ 0.44 | 🌡️47°C | 6.7 GiB | 2023-06-26 20:49:10
[...]
It can be customized by creating ~/.config/goobar/config.scm. This file
should return a list of either <status> objects, or plain strings.
Statuses or strings can be "annotated" to provide extra properties, such as
custom color, width, alignment, etc. See man 7 swaybar-protocol for a
list of properties, all of which are supported by (goobar annotation).
Example:
(use-modules (status)
(status collector backlight)
(status collector battery)
(status collector cpu-usage)
(status collector disk)
(status collector ipv6)
(status collector load)
(status collector network-rate)
(status collector pulseaudio)
(status collector time)
(status collector wifi)

(list (disk-status "/" #:degraded-threshold "80%")
(disk-status "/home")
(ipv6-status
;; Don't bother printing the full IPv6 address.
#:format (lambda (status)
(if (status-good? status) "✔" "❌")))

(if (status-bad? status)
"down"
(let ((data (status-data status)))
(format #f "~a (~d%~a)"
(assoc-ref data 'ssid)
(assoc-ref data 'quality)
;; Print bitrate only when available.
(format #f "~@[, ~a~]"
(and=> (assoc-ref data 'bitrate)
format-bitrate)))))))
;; Disable separator to meld with the rate status below.
#:separator? #f)
(network-rate-status "wlp0s20f3"
#:format
(lambda (status)
(let* ((data (status-data status))
(down (assoc-ref data 'rx-bytes/sec)))
(format #f "⬇ ~a" (format-bytes down)))))
(battery-status "BAT0")
;; Remove silly load icon.
(annotate (load-status '5min) #:icon #f)
(cpu-usage-status)
(pulseaudio-status "0")
(backlight-status)
(annotate (format #f "Hi ~a!" (getenv "USER")) #:color (random-color))
(time-status "%d/%m %T"))
Pull requests welcome! There are a bunch of TODOs in the code, and probably even more bugs. Feel free to add more status collectors. Note that the status collector API is subject to change, feedback wanted.
Planned features that are not yet implemented:
- Bidirectional communication (click events)
- More output formats (dzen2, xmobar, etc)
Unless otherwise noted, all code is GNU General Public License version 3, or (at your option) any later version.
