[RFC PATCH 04/13] walken: add handler to git_config

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



For now, we have no configuration options we want to set up for
ourselves, but in the future we may need to. At the very least, we
should invoke git_default_config() for each config option; we will do so
inside of a skeleton config callback so that we know where to add
configuration handling later on when we need it.
