libvcs is a lite, typed, pythonic tool box for
detection and parsing of URLs, commanding, and syncing with git
, hg
, and svn
. Powers
vcspull.
- URL Detection and Parsing: Validate and parse Git, Mercurial, and Subversion URLs.
- Command Abstraction: Interact with VCS systems through a Python API.
- Repository Synchronization: Clone and update repositories locally via Python API.
- py.test fixtures: Create temporary local repositories and working copies for testing for unit tests.
Supports Python 3.9 and above, Git (including AWS CodeCommit), Subversion, and Mercurial.
To get started, see the quickstart guide for more information.
$ pip install --user libvcs
Easily validate and parse VCS URLs using the
libvcs.url
module:
>>> from libvcs.url.git import GitURL
>>> GitURL.is_valid(url='https://github.com/vcs-python/libvcs.git')
True
>>> from libvcs.url.git import GitURL
>>> git_location = GitURL(url='git@github.com:vcs-python/libvcs.git')
>>> git_location
GitURL(url=git@github.com:vcs-python/libvcs.git,
user=git,
hostname=github.com,
path=vcs-python/libvcs,
suffix=.git,
rule=core-git-scp)
Switch repo libvcs -> vcspull:
>>> from libvcs.url.git import GitURL
>>> git_location = GitURL(url='git@github.com:vcs-python/libvcs.git')
>>> git_location.path = 'vcs-python/vcspull'
>>> git_location.to_url()
'git@github.com:vcs-python/vcspull.git'
# Switch them to gitlab:
>>> git_location.hostname = 'gitlab.com'
# Export to a `git clone` compatible URL.
>>> git_location.to_url()
'git@gitlab.com:vcs-python/vcspull.git'
See more in the parser document.
Abstracts CLI commands for git(1)
, hg(1)
, svn(1)
via a lightweight subprocess
wrapper.
import pathlib
from libvcs.cmd.git import Git
git = Git(path=pathlib.Path.cwd() / 'my_git_repo')
git.clone(url='https://github.com/vcs-python/libvcs.git')
Above: libvcs.cmd.git.Git
using
Git.clone()
.
Synchronize your repositories using the
libvcs.sync
module.
import pathlib
from libvcs.sync.git import GitSync
repo = GitSync(
url="https://github.com/vcs-python/libvcs",
path=pathlib.Path().cwd() / "my_repo",
remotes={
'gitlab': 'https://gitlab.com/vcs-python/libvcs'
}
)
# Update / clone repo:
>>> repo.update_repo()
# Get revision:
>>> repo.get_revision()
u'5c227e6ab4aab44bf097da2e088b0ff947370ab8'
Above: libvcs.sync.git.GitSync
repository
object using
GitSync.update_repo()
and
GitSync.get_revision()
.
libvcs pytest plugin provides py.test fixtures to swiftly create local VCS repositories and working repositories to test with. Repositories are automatically cleaned on test teardown.
import pathlib
from libvcs.pytest_plugin import CreateRepoPytestFixtureFn
from libvcs.sync.git import GitSync
def test_repo_git_remote_checkout(
create_git_remote_repo: CreateRepoPytestFixtureFn,
tmp_path: pathlib.Path,
projects_path: pathlib.Path,
) -> None:
git_server = create_git_remote_repo()
git_repo_checkout_dir = projects_path / "my_git_checkout"
git_repo = GitSync(path=str(git_repo_checkout_dir), url=f"file://{git_server!s}")
git_repo.obtain()
git_repo.update_repo()
assert git_repo.get_revision() == "initial"
assert git_repo_checkout_dir.exists()
assert pathlib.Path(git_repo_checkout_dir / ".git").exists()
Under the hood: fixtures bootstrap a temporary $HOME
environment in a
TmpPathFactory
for automatic cleanup and pytest-xdist
compatibility..
