Dear Café, I just wrote myself a small (~ 200 LOC) calendar application today. https://bitbucket.org/rainmaker/apphointments Comments/Patches welcome. From the readme: apphointments - A simple functional calendar ============================================ This is a "UI = Code" calendar application: You create an event by writing code that defines it. To see what's up next, you create a "report", i.e. a summary of the events in a certain time range such as 'thisWeek'. This is done by haskell functions again from GHCi or ghc -e. See example.hs. Using just haskell instead of our own language or GUI allows great flexibility in both defining events and generating reports. See e.g. the 'lecture' combinator from Apphointments.Util. Status ------ Works for me, but has no features yet. See TODO. Credits ------- Created by Steffen Schuldenzucker <sschuldenzucker@uni-bonn.de>
