It's hlint: http://community.haskell.org/~ndm/hlint/ e.g.: # sudo apt-get install hlint # hlint src (where src is the folder containing Haskell files) or # hlint src --report to generate an HTML report. On Sat, Feb 23, 2013 at 10:25 PM, Emanuel Koczwara < poczta@emanuelkoczwara.pl> wrote:
Hi,
Why GHC doesn't tell me such things like hpaste? (example here: http://hpaste.org/82917)
27:12: Error: Use replicateM Found: sequence $ replicate gridSize getLine Why not: Control.Monad.replicateM gridSize getLine
50:14: Warning: Use list comprehension Found: if y > 0 then [(UP, (x, y - 1))] else [] Why not: [(UP, (x, y - 1)) | y > 0]
81:1: Error: Eta reduce Found: sortByPathCost p ps = sortBy compareHeuristic ps Why not: sortByPathCost p = sortBy compareHeuristic
Can I enable this kind of verbosity in GHC somehow?
