Tools for writing Haskell programs
- 1. Tools for writing Haskell Programs
- 2. TL;DR: Haskell has excellent tooling.
- 7. ls *.hi *.o
- 8. ghc --make blah --hi- dir=Urgh
- 9. Cabal
- 10. Cabal $ mkdir my_project && cd my_project $ cabal init # Create your new project! $ cabal configure $ cabal build # Outputs are in ./dist
- 11. Share It - Hackage! $ cabal upload dist/kit-0.1.tar.gz
- 12. $ cabal install kit Dependency manager for Obj-C code
- 13. Discovering
- 16. > 2100 packages
- 18. Hayoo
- 19. • “map” • “map package:containers” • “map module:Data.Map” • “name:map”
- 21. Name search...
- 22. HOOGLE
- 23. (a -> b) -> [a] -> [b]
- 25. $ cabal install hoogle $ hoogle “[a] -> Int”
- 26. Improving
- 27. HLint
- 28. • f = do blah -- f = blah • f = (x) + 3 -- f = x + 3 • Bracket reduction. Do-Notation help.
- 30. ~= ghci + goodies
- 31. @pl/@unpl
- 32. @pl (a -> a + x) (+x)
- 33. @unpl (++x) . show (d -> (show d) ++ x)
