live-source

basic use:

1. create client haskell script without a module name
2. give the script a function named liveMain

eg :

 -- file test.hs
 liveMain = print 2

3. open ghci

Prelude> import LiveSource
Prelude LiveSource> repeatOnModification "test.hs"
2

4. edit file test.hs and save it

eg :

 -- file test.hs
 
liveMain = print (take 10 [1..])

Ghc should now run the IO.

Prelude> import LiveSource
Prelude LiveSource> repeatOnModification "test.hs"
2
