looks for functions given a set of example input/outputs
|Latest on Hackage:||0.1.0.1|
This package is not currently in any snapshots. If you're interested in using it, we recommend adding it to Stackage Nightly. Doing so will make builds more reliable, and allow stackage.org to host generated Haddocks.
Search for haskell functions in installed libraries by providing input/output examples.
Hoogle has to be installed.
Example session 1:
brauner@worf:~$ haltavista 2 2 4 <EOF> Prelude (*) Prelude (+) Prelude (^)
Example session 2 (refining search 1):
brauner@worf:~$ haltavista 2 2 4 1 2 3 <EOF> Prelude (+)
Example session 3 (higher-order functions):
brauner@worf:~$ haltavista (+1) (+2) (1,1) (2,3) <EOF> Data.Graph.Inductive.Query.Monad (><)
Under the hood, uses:
- hint for type inference;
- hoogle to get a list of candidate functions;
- hint for testing.
Hoogle calling facility has been copy-pasted (and later modified) from the Yi project.
- catch stack overflows (is that possible?)
- catch other errors (should do but doesn't for some reason)
