Defined in Darcs.Repository.Format

identifyRepoFormat :: String -> IO RepoFormat Source #

Identify the format of the repository at the given location (directory, URL, or SSH path). Fails if we weren't able to identify the format.

tryIdentifyRepoFormat :: String -> IO (Either String RepoFormat) Source #

Identify the format of the repository at the given location (directory, URL, or SSH path). Return Left reason if it fails, where reason explains why we weren't able to identify the format. Note that we do no verification of the format, which is handled by readProblem or writeProblem on the resulting RepoFormat.

createRepoFormat :: PatchFormat -> WithWorkingDir -> RepoFormat Source #

Create a repo format. The first argument is whether to use the old (darcs-1) format; the second says whether the repo has a working tree.

writeRepoFormat :: RepoFormat -> FilePath -> IO () Source #

Write the repo format to the given file.

writeProblem :: RepoFormat -> Maybe String Source #

writeProblem source returns Just an error message if we cannot write to a repo in format source, or Nothing if there's no such problem.

readProblem :: RepoFormat -> Maybe String Source #

readProblem source returns Just an error message if we cannot read from a repo in format source, or Nothing if there's no such problem.

transferProblem :: RepoFormat -> RepoFormat -> Maybe String Source #

transferProblem source target returns Just an error message if we cannot transfer patches from a repo in format source to a repo in format target, or Nothing if there are no such problem.

formatHas :: RepoProperty -> RepoFormat -> Bool Source #

Is a given property contained within a given format?

addToFormat :: RepoProperty -> RepoFormat -> RepoFormat Source #

Add a single property to an existing format.

removeFromFormat :: RepoProperty -> RepoFormat -> RepoFormat Source #

Remove a single property from an existing format.
