From 7115d1ec162b4059b3e8e8f84bd8d5898c1db025 Mon Sep 17 00:00:00 2001 From: Joey Hess Date: Wed, 14 May 2014 19:41:05 -0400 Subject: moved source code to src This is to work around OSX's brain-damange regarding filename case insensitivity. Avoided moving config.hs, because it's a config file. Put in a symlink to make build work. --- Utility/Data.hs | 17 ----------------- 1 file changed, 17 deletions(-) delete mode 100644 Utility/Data.hs (limited to 'Utility/Data.hs') diff --git a/Utility/Data.hs b/Utility/Data.hs deleted file mode 100644 index 2df12b36..00000000 --- a/Utility/Data.hs +++ /dev/null @@ -1,17 +0,0 @@ -{- utilities for simple data types - - - - Copyright 2013 Joey Hess - - - - License: BSD-2-clause - -} - -module Utility.Data where - -{- First item in the list that is not Nothing. -} -firstJust :: Eq a => [Maybe a] -> Maybe a -firstJust ms = case dropWhile (== Nothing) ms of - [] -> Nothing - (md:_) -> md - -eitherToMaybe :: Either a b -> Maybe b -eitherToMaybe = either (const Nothing) Just -- cgit v1.2.3
