README
¶
Hgo is a collection of Go packages providing read-access to local Mercurial repositories. Only a subset of Mercurial's functionality is supported. It is possible to access revisions of files and to read changelogs, manifests, and tags.
Hgo supports the following repository features:
* revlogv1
* store
* fncache (no support for hash encoded names, though)
* dotencode
The Go packages have been implemented from scratch, based on information found in Mercurial's wiki.
The project should be considered unstable. The BUGS file lists known issues yet to be addressed.
cmd/hgo contains an example program that implements a few commands similar to a subset of Mercurial's hg.

func (bh *BranchHeads) Add(name, id string)
Associate a new branch with a changeset ID.
func (*BranchHeads) Sort ¶
func (bh *BranchHeads) Sort()

// contains filtered or unexported fields
}
func OpenRepository ¶
func OpenRepository(root string) (r *Repository, err error)
Open a repository located at the given project root directory, i.e. a directory that contains a subdirectory named ‘.hg’.

func (r *Repository) BranchHeads() (*BranchHeads, error)
BranchHeads parses and returns the repository's branch heads.
func (*Repository) NewStore ¶
func (r *Repository) NewStore() *store.Store
NewStore returns a new Store instance that provides access to the repository's changelog, manifests, and filelogs.
func (*Repository) RelFileName ¶
func (r *Repository) RelFileName(name string) (rel string, err error)
