lite-xl-easingpreview

Easing previewer for Lite XL. Currently only works with Lua.

How to use

Run easing-preview:show (this one mapped to ctrl+shift+e by default) over the signature of a Penner easing function:

function linear(t, b, c, d) -- execute here
  return c * t / d + b
end

Click anywhere else (or run easing-preview:hide (mapped to ctrl+alt+e)) to hide the prompt.

Config

local easing_previewer = config.plugins.easing_previewer
easing_previewer.displayWidth = 150
easing_previewer.displayHeight = 100

easing_previewer.arrowWidth = 0.2 -- normalized
easing_previewer.arrowHeight = 0.2 -- normalized (based on height of the display (should probably change that))

easing_previewer.pointSize = 5
easing_previewer.steps = 100 -- resolution of the graph
easing_previewer.padding = 10

There's also a config spec, in case you use settings.
