kids.vcs
kids.vcs
is a Python library providing GIT helpers. Would have
named it kids.git
if it didn't messed everything with github.
It's part of 'Kids' (for Keep It Dead Simple) library.
Features
using kids.vcs
:
- You can manage and access your git repository, commits, logs, or git config.
Compatibility
This code is python2 and python3 ready. It wasn't tested on windows.
Installation
You don't need to download the GIT version of the code as kids.vcs
is
available on the PyPI. So you should be able to run:
pip install kids.vcs
If you have downloaded the GIT sources, then you could add install the current version via traditional:
python setup.py install
And if you don't have the GIT sources but would like to get the latest master or branch from github, you could also:
pip install git+https://github.com/0k/kids.vcs
Or even select a specific revision (branch/tag/commit):
pip install git+https://github.com/0k/kids.vcs@master
Usage
Let's play with a new git repository, let's first create temporary directory:
>>> from __future__ import print_function >>> import tempfile, os >>> old_cwd = os.getcwd() >>> tmpdir = tempfile.mkdtemp() >>> os.chdir(tmpdir)
Let's now create a real git repository:
>>> from kids.vcs import git
This first command will create a new directory and launch git init
and
and will return the new GitRepos
object:
>>> r = git.GitRepos.create("repos", ... email="committer@example.com", ... name="The Committer")
You might also want to only use an existing directory and launch git init
then
use:
>>> r = git.GitRepos.init("repos")
Or, if wanting to use an already existing folder already initialised:
>>> r = git.GitRepos("repos")
By default, the current directory is used and the top-most git repository that contains the current directory will be used as the master git repository.
Avoid instantiating a non-existent git repository:
>>> git.GitRepos("/") Traceback (most recent call last): ... OSError: Not a git repository ('/' or any of the parent directories).
Git commands shortcut
Aside from all the helpers that will be exposed in the following section, a
GitRepos
object provides a handy .git
attribute to directly tap on
the git command line:
>>> print(r.git.rev_parse(is_bare_repository=True)) false
A few things to note:
- the method name is the git command you want to launch
-
_
(underscores) are swapped for-
. - there are 2 different way to use the methods:
- provide one unique array of strings that will simply appended on the command line.
- provide string positional arguments and keyword arguments:
- keyword arguments are options... :
- a double-dash will be added before the keyword if it is composed of more than one char
- a single dash will be added before the keyword in cas it a single character keyword.
-
_
(underscores) are swapped for-
in keyword name - and value is appended just after on the command line.
- positional arguments are appended AFTER all the options...
- keyword arguments are options... :
- the method return value is the space-stripped standard output of the command sent.
To illustrate this and the following points:
>>> print(r.git.commit( ... message='new: first commit', ... author='Bob <bob@example.com>', ... date='2000-01-01 10:00:00', ... allow_empty=True)) [master (root-commit) ...] new: first commit Author: Bob <bob@example.com> Date: Sat Jan 1 10:00:00 2000 ... >>> print(r.git.tag("0.0.1")) >>> print(r.git.commit( ... message='new: second commit', ... author='Alice <alice@example.com>', ... date='2000-01-02 11:00:00', ... allow_empty=True)) [master ...] new: second commit Author: Alice <alice@example.com> Date: Sun Jan 2 11:00:00 2000 ... >>> print(r.git.tag("0.0.2"))
Access core informations
You can get interesting information fron the git repository itself:
>>> print(r.toplevel) /.../repos >>> r.bare False >>> print(r.gitdir) /.../repos/.git
Read git config
We can access the config thanks to:
>>> r.config <...GitConfig...> >>> print(r.config["core.filemode"]) true
You can also instanciate directly the GitConfig
class:
>>> from kids.vcs import git >>> print(git.GitConfig("repos")["core.filemode"]) true
Without any repository, it's the current repository that should be
used, and if none, well it should answer as much as a normal git
config
would:
>>> git.GitConfig()["core.filemode"] Traceback (most recent call last): ... KeyError: 'core.filemode' >>> os.chdir("repos") >>> print(git.GitConfig()["core.filemode"]) true
Git commit access
We can access interesting information per commit:
>>> r.commit("HEAD") <GitCommit 'HEAD'>
And several information are available:
>>> print(r.commit("HEAD").author_name) Alice >>> print(r.commit("master").subject) new: second commit
You can access to all of these:
>>> print(", ".join(sorted(git.GIT_FORMAT_KEYS))) author_date, author_date_timestamp, author_email, author_name, body, committer_date_timestamp, committer_name, decorate_string, parent_list_string, raw_body, sha1, sha1_short, subject
There's a convienience attribute date
also:
>>> print(r.commit("0.0.2").date) 2000-01-02
Tags
You can get the list of tags:
>>> r.tags [<GitCommit ...'0.0.1'>, <GitCommit ...'0.0.2'>]
Logs
You can access all commits via:
>>> list(r.log()) [<GitCommit ...>, <GitCommit ...>]
and provide wich commit ancestry to include or to exclude (see git
log
):
>>> list(r.log(["HEAD", "^0.0.1", ])) [<GitCommit ...>]
Contributing
Any suggestion or issue is welcome. Push request are very welcome, please check out the guidelines.
Push Request Guidelines
You can send any code. I'll look at it and will integrate it myself in the code base and leave you as the author. This process can take time and it'll take less time if you follow the following guidelines:
- check your code with PEP8 or pylint. Try to stick to 80 columns wide.
- separate your commits per smallest concern.
- each commit should pass the tests (to allow easy bisect)
- each functionality/bugfix commit should contain the code, tests, and doc.
- prior minor commit with typographic or code cosmetic changes are
very welcome. These should be tagged in their commit summary with
!minor
. - the commit message should follow gitchangelog rules (check the git log to get examples)
- if the commit fixes an issue or finished the implementation of a feature, please mention it in the summary.
If you have some questions about guidelines which is not answered here,
please check the current git log
, you might find previous commit that
would show you how to deal with your issue.
