Lebar

Intro

Lebar is a work in progress, proof of concept, system bar written in fennel and compiled to lua.

LÖVE

Lebar is built using the LÖVE framework. This isn’t an obvious choice for an application such as this, but neither is writing in Fennel.

Configuration

Lebar is bundled with a default configuration but it can be overridden with a custom configuration created in ~/.local/share/love/lebar/rc.fnl

(local config {})

(local blocks (require "blocks.fnl"))
(local themes (require "themes.fnl"))
(local lib (require "lib.fnl"))

(set config.refresh-seconds 0.001)

;; When set to true this will cause the render loop to 
;; pause and wait for something to appear on the draw channel
;; When set to false the render loop will only pause based on
;; config.refresh-seconds
