Yet another "bar" program for wlroots-basd Wayland compositors, but
|
|
|
|
|
this one is written in [Fennel](https://fennel-lang.org/) and
|
|
|
|
|
therefore better than all the others because it is more niche.
|
|
|
|
|
|
|
|
|
|
More seriously: you might prefer this over another status bar program
|
|
|
|
|
if you want fine-grained control over what is shown in your bar and
|
|
|
|
|
you are happy to exert that control in a Lua-based Lisp language.

## Plan
|
|
|
|
|
|
|
|
|
|
* [X] use gtk-layer-shell to put it in a layer
|
|
|
|
|
* [] update only at relevant intervals
|
|
|
|
|
* [] do we need file poll support? prolly not if we're calling every 200ms
|
|
|
|
|
* [] cache icon pixbufs
|
|
|
|
|
* [] update image/label widget instead of destroying
|
|
|
|
|
* [] allow height customisation
|
