python-anyvcs

A Python abstraction layer for multiple version control systems.

python-anyvcs provides a Python interface to work with version control repositories through a consistent interface regardless of the underlying repository type. It currently supports:

• Git repositories (either bare or non-bare)
• Mercurial repositories
• Subversion master repositories (those created with svnadmin create)

The focus is on read-only operations, but a few write operations are supported (like creating new repositories or loading a Subversion dumpfile).

If you are looking for an interface to work with working copies of version control repositories, either contribute to this project or look elsewhere.

Supported Operations

• ls() - list files
• cat() - read file contents
• readlink() - read symbolic link target
• branches() - list branches
• bookmarks() - list bookmarks (Mercurial only)
• tags() - list tags
• heads() - list all branches, bookmarks, tags, etc.
• tip() - find the tip of a named head
• empty() - determine if the repository contains any commits
• __len__() - count the number of commits in the repository
• __contains__() - determine if the repository contains the given revision
• log() - get commit logs
• changed() - list files that were changed in a given revision
• pdiff() - get diff that a given revision introduced
• diff() - get diff between any two revisions
• ancestor() - find most recent common ancestor of any two revisions
• blame() - blame (a.k.a. annotate) lines of a file
• canonical_rev() - get the canonical revision identifier
• compose_rev() - compose a revision identifier which encodes branch and revision
• clone() - clone an existing repository
• private_path - a path in the repository where untracked data can be stored
• dump() - create a Subversion dumpfile (Subversion only)
• load() - load a Subversion dumpfile (Subversion only)

Operations that are not natively supported by the underlying version control system are implemented in this library.

Example

>>> from pprint import pprint
>>> import anyvcs
>>> repo = anyvcs.open('/path/to/repo')
>>> repo.branches()
['1.0_develop', '1.0_master', 'develop', 'master']
>>>
>>> log = repo.log(limit=3)
>>> pprint([commit.message for commit in log])
["Merge branch 'release/1.2.0' into develop\n",
 "Merge branch 'release/1.2.0'\n",
 'add README symlink to keep python happy\n',
 'add copyright information\n']
>>>
>>> ls = repo.ls('master', '/')
>>> pprint(ls)
[{'name': '.gitignore', 'path': '.gitignore', 'type': 'f'},
 {'name': 'AUTHORS', 'path': 'AUTHORS', 'type': 'f'},
