Libraries and tools/Time library
The API is well designed, but not particularly obvious for simple use cases. Hopefully we can collect a number of common examples here.
If you want to use Data.Time with GHC 6.4, you will need to install a number of libraries it depends on first. The process is:
darcs get --partial http://www.cse.unsw.edu.au/~dons/code/fps normal cabal configure, build, install
darcs get http://darcs.haskell.org/packages/Win32 Edit Win32.cabal, add fps to build-depends. normal cabal configure, build, install
darcs get http://semantic.org/TimeLib/TimeLib There are two packages here: time and fixed. Ignore time. Go into fixed and do cabal configure, build, install
darcs get http://darcs.haskell.org/packages/time Edit time.cabal, add fixed and Win32 to build-depends. create Setup.hs: import Distribution.Simple main = defaultMainWithHooks defaultUserHooks From MSYS shell, not Windows cmd.exe: autoreconf runhaskell Setup.hs configure runhaskell Setup.hs build runhaskell Setup.hs install
