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 add [<file>] hg addremove [<file>] hg archive [-t type] [-r rev] <destination> hg bookmarks [-r rev] [-f] [-m name newname | -d name | -i name | name] hg branch hg branches hg clone hg commit [files] [-u name] [--close-branch] hg diff hg heads hg id hg incoming hg init hg log hg merge (fails on conflict) hg outgoing hg paths hg pull [<source>] hg push [<destination>] hg remove hg rename <source> <destination> hg revert hg root hg status hg tag hg tags hg update <rev> hg version
You also have access to the configuration (config, configbool, configlist) just as in the internal Mercurial API. The repository supports slicing and indexing notation.
>>> import hgapi >>> repo = hgapi.Repo("test_hgapi") # existing folder >>> repo.hg_init() >>> 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 >>> open('test_hgapi/file.txt', 'a').write('\nAdded line') # doctest: +IGNORE_RESULT >>> diff = repo.hg_diff() # returns list of diffs >>> assert diff['filename'] == 'file.txt' >>> assert '+Added line' in diff['diff']
Easiest is easy_install or pip from PyPy:
pip install hgapi
Otherwise, download the source, make sure you have setuptools installed, and then run:
python setup.py install
Do not hesitate to send requests, issues or perform code reviews! When developing please follow the pep8 guidelines (see http://legacy.python.org/dev/peps/pep-0008/) and do use tox to check your code:
Tox will make sure that hgapi runs on Python 2.7, 3.2, 3.3 and 3.4; and it will check the pep8 compliance.
