From 4d1402a1a7d87767267d48a77998e4fb13395b31 Mon Sep 17 00:00:00 2001 From: Pavan Rikhi Date: Sat, 17 Mar 2018 22:48:24 -0400 Subject: Split Modules into Library & Executable Structure Move the Main module to a new `app` directory. All other modules have been nested under the `Xmobar` name. Lots of module headers & imports were updated. --- src/Window.hs | 214 ---------------------------------------------------------- 1 file changed, 214 deletions(-) delete mode 100644 src/Window.hs (limited to 'src/Window.hs') diff --git a/src/Window.hs b/src/Window.hs deleted file mode 100644 index 829ab8d..0000000 --- a/src/Window.hs +++ /dev/null @@ -1,214 +0,0 @@ ------------------------------------------------------------------------------ --- | --- Module : Window --- Copyright : (c) 2011-18 Jose A.
