-Xresources
-==========
+# Xresources
-Description
------------
-This patch allows to handle settings from Xresources. It differs from xrdb patch in that it can handle any kind of setting as opposed to only color settings.
+Runtime configuration using X resources.
-The -20210314 patch adds an example on how you could set a custom font.
+## Description
-Settings in config.h
---------------------
-In `resources` struct is written the name, the type, and the address of the setting.
+This patch adds X resources support to dwm. At startup, dwm reads the configured
+X resources and applies them.
- Name Type Address
- --------------------------------------------------------
- "nmaster" INTEGER &nmaster
- "mfact" FLOAT &mfact
- "color1" STRING &color1
+This patch also adds a hotkey (`Modkey` + `F5` by default) which reloads the
+configured resources during runtime.
-In Xresources file setting names shoud be prefixed with "dwm."
+## Configuration
- dwm.nmaster:
- dwm.mfact:
- dwm.color1:
+The `resources` array contains list of settings to load from X resources:
-This patch is a port of the st patch of the same name, it also borrows some code from dwm's xrdb patch, so a thank is in order for the authors of those patches.
