List files in a git repo #56

Open hjwylde opened 9 years ago

hjwylde commented 9 years ago

Hey, I'm trying to list all files in a git repo but unsure how to accomplish to this. Ideally it would have similar behaviour to git ls-files.

I tried using:

+    tree <- lookupTree =<< createTree readIndex
+
+    files <- readFileTree' tree "." False

But that seemed to not list everything:

I'm probably misunderstanding how to use trees and the index, so any help is appreciated :).

At least in the current version, this works:


        Just ref <- Git.resolveReference "HEAD"
        commit <- Git.lookupCommit $ Tagged ref
        tree <- Git.lookupTree $ Git.commitTree commit
        xs <- Git.listTreeEntries True tree 
        return $ map fst xs
