hgapi is a pure-Python API to Mercurial, that uses the command-line interface instead of the internal Mercurial API. The rationale for this is twofold: the internal API is unstable, and it is GPL.

hgapi works for all versions of Mercurial, and will instantly reflect any changes to the repository (including hgrc). It also has a really permissive license (do whatever you want, don't blame me).

For example of code that uses this API, take a look at https://bitbucket.org/haard/autohook which now uses hgapi exclusively. Add any feature requests or bugs found to the issue tracker.

So far, the API supports:

hg init
hg id
hg add <file>
hg commit [files] [-u name] [--close-branch]
hg update <rev>
hg heads
hg log
hg remove
hg status
hg merge (fails on conflict)
hg revert
hg branch
hg branches
hg clone

You also have access to the configuration (config, configbool, configlist) just as in the internal Mercurial API. The repository supports slicing and indexing notation.

Example usage::

>>> import hgapi >>> repo = hgapi.Repo.hg_init("test_hgapi") #existing folder >>> repo.hg_add("file.txt") #already created but not added file >>> repo.hg_commit("Adding file.txt", user="me") >>> str(repo['tip'].desc) 'Adding file.txt' >>> len(repo[0:'tip']) 1

Easiest is easy_install or pip from PyPy:

pip install hgapi

or:

easy_install hgapi

Otherwise, download the source, make sure you have setuptools installed, and then run:

python setup.py install
