Retrie does not apply forward rule in Windows (revisit after facebookincubator/retrie#30)

[jneira]

With a simple example took from retrie readme:

module MyModule2 where

myMaybe :: b -> (a -> b) -> Maybe a -> b
myMaybe d f mb = case mb of
  Nothing -> d
  Just x -> f x

type MyMaybe = Maybe Int

{-# RULES "myRule" forall x. myMaybe Nothing Just x = x #-}

foo :: Maybe Int
foo = myMaybe Nothing Just (Just 5)

First minor thing: code actions are duplicated:

Moreover the forward rules are not applied:

Maybe the output of grep could be significative:

xargs grep -l 'myMaybe[[:space:]]\+Nothing[[:space:]]\+Just'

I never got around to adding a test suite for the retrie extension, what a shame. It shouldn't be too much work to add one following the same approach of golden tests used in the Eval plugin test suite.

Retrie relies on grep to prefilter the set of relevant files/ As the output shows, your version of grep is not matching any instance of the rhs of the rule. So this is really a retrie bug, it should run some pre-checks on the grep binary to make sure it works as expected. What grep, if any, do you have on the PATH?

Hi, thanks for response, i have the gnu grep version:

C:\Users\atrey>grep --version
GNU grep 2.5.4
....
C:\Users\atrey>where grep

C:\Users\atrey>where xargs

but i have not xargs.

Definitely is a retry problem and should be fixed upstream:

it works in a msys2 console:

$ retrie -v 2 --rule-forward MyModule2.myRule
hgIgnorePred: hg: readCreateProcessWithExitCode: does not exist (No such file or directory)
gitIgnorePred: fatal: not a git repository (or any of the parent directories): .git

Reading VCS ignore failed! Continuing without ignoring.

shellCmd:
grep -R --include="*.hs" -l 'infix' D:\dev\ws\haskell\cabal-test\src

So i guess putting msys2 shell executables on scope may work too (to check)
