-> FilePath

The full path to the current symlink

Returns the full path to the current symlink.

defaultSuccessHandler :: a -> ReaderT Config IO () Source

Default method to run on deploy success.

defaultErrorHandler :: FailureResult -> ReaderT Config IO () Source

Default method to run on deploy failure. Emits a failure message and exits with a status code of 1.

isReleaseString Source

Arguments

:: ReleaseFormat

rollback Source

Arguments

runRC Source

Arguments

:: ((Int, String) -> ReaderT Config IO a)

Error handler

-> (a -> ReaderT Config IO a)

Success handler

-> Config

Hapistrano deployment configuration

-> Hapistrano a

The remote command to run

-> IO a
