Description

Provides high-level Git functions like commit, checkout, status, log,...

All functions of this module run in the Ctx monad, common to all VCS. On unexpected behavior, these functions will throw a VCSException.

checkoutSource

Arguments

:: Maybe String

Commit ID

-> Maybe String

Branchname. If specified, git checkout -b <branchname> will be executed.

-> Ctx () 

Checkout the index to some commit ID. Executes git checkout.

status :: Ctx [Status]Source

Return status of the repository as a list of Status. Executes git status.

simpleLogSource

myInitRepoFn = do
    let config = makeConfig "path/to/repo" Nothing Nothing
    runVcs config $ initDB False

data Config Source

Configuration of the Ctx the VCS commands will be executed in.

Config 

Fields

configCwd :: Maybe FilePath

Path to the main directory of the repository. E.g. for Git: the directory of the repository containing the .git config directory.

configPath :: Maybe FilePath

Path to the vcs executable. If Nothing, the PATH environment variable will be search for a matching executable.

configAuthor :: Maybe Author

Author to be used for different VCS actions. If Nothing, the default for the selected repository will be used.

configEnvironment :: [(String, String)]

Constructors

Author 

Fields

data Status Source

Status of a file managed by the respective VCS.

Instances

data Modification Source

Flags to describe the state of a file.
