-- Hyprland configuration, in the style of Protesilaos Stavrou's Sway config.
-- Ref: https://github.com/protesilaos/dotfiles/tree/master/wayland-tc/.config/sway
--
-- Prot runs Sway (i3-style, manual tiling); this is Hyprland (dwindle,
-- dynamic tiling). Bindings and colours are carried over faithfully; the
-- places where Hyprland has no equivalent are marked "SUBSTITUTION" below.

---- MY PROGRAMS ----
---------------------

-- Prot uses gnome-terminal. SUBSTITUTION: ghostty, which is already
-- installed here (and you said no kitty).
local terminal    = "ghostty"
local fileManager = "dolphin"

-- Prot's exact wofi invocation, minus the `| xargs swaymsg exec --` pipe,
-- which exists only to hand the command back to Sway. Hyprland execs directly.
local menu = "wofi -G -I -i -n --show drun"

-- Prot points at ~/Pictures/light.jpg, which does not exist here.
-- SUBSTITUTION: one of your own wallpapers. Change this one string to swap it.
local wallpaper = os.getenv("HOME") .. "/Pictures/wallhaven-8gdrq2_2560x1440.png"

---- LOOK AND FEEL ----
-----------------------

-- Prot's colours, from his 'modus-themes' for Emacs:
--   #ffffff white    focused border (matches mako border-color)
--   #f78fe7 magenta  focused-but-inactive border
--   #575757 grey     unfocused border
--   #a60000 red      urgent
--   #ffa200 orange   indicator
--
-- SUBSTITUTION: Sway's `client.*` lines set five colours per window state
-- (border, background, text, indicator, child_border) because Sway draws
-- title bars. Hyprland has no title bars, so only the border colours carry
-- over. The backgrounds/text/indicator values have nowhere to go, and
-- Hyprland has no global "urgent" border colour at all.
