Testable PropFile

inDir :: FilePath -> Build a -> Build a

Run a command in a different working directory. Throws an error if the directory doesn't exist.

inScratchDir :: FilePath -> Build a -> Build a

Create a new directory with the given name, run a command within it, then change out and recursively delete the directory. Throws an error if a directory with the given name already exists.

clobberDir :: FilePath -> Build ()

Delete a dir recursively if it's there, otherwise do nothing. Unlike removeDirectoryRecursive, this function does not follow symlinks, it just deletes them.

ensureDir :: FilePath -> Build ()

Create a new directory if it isn't already there, or return successfully if it is.

withTempFile :: (FilePath -> Build a) -> Build a

Create a temp file, pass it to some command, then delete the file after the command finishes.
