dotfiles/hypr/theme/rules.lua

-- Was: theme/rules.conf
--
-- The old file already used the 0.53+ `windowrule { name/match:class }` block
-- form, so this is a fairly direct transcription:
--   match:class = <regex>  ->  match = { class = <regex> }
--   float = on             ->  float = true
--   center = 1             ->  center = true
--   size = (a) (b)         ->  size = { "a", "b" }

-- Reusable size presets (monitor-relative expressions)
local size_large = { "monitor_w*0.7", "monitor_h*0.7" }
local size_mid   = { "monitor_w*0.5", "monitor_h*0.5" }
local size_mini  = { "monitor_w*0.3", "monitor_h*0.4" }
local size_side  = { "monitor_w*0.3", "monitor_h*0.9" }
