This Informational PEP collects information about git. There is, of
course, a lot of documentation for git, so the PEP concentrates on
-more complex issues, scenarios and topics.
+more complex issues, scenarios and examples.
The plan is to extend the PEP in the future collecting information
about equivalence of Mercurial and git scenarios to help migrating
Git is accompanied with a lot of documentation, both online and
offline.
+
Documentation for starters
--------------------------
`Git workflows
<https://www.kernel.org/pub/software/scm/git/docs/gitworkflows.html>`_.
+
Advanced documentation
----------------------
`Git Wiki <https://git.wiki.kernel.org/index.php/Main_Page>`_.
+
Offline documentation
---------------------
`TortoiseGit <https://tortoisegit.org/>`_ is a Windows Shell Interface
to Git based on TortoiseSVN; open source.
+
Initial configuration
---------------------
the currently checked out branch is ``master``. That is, it's assumed
you have done something like that::
- $ git clone http://git.python.org/python.git
+ $ git clone https://git.python.org/python.git
$ cd python
$ git branch v1 origin/v1
The same result can be achieved with commands::
- $ git clone -b v1 http://git.python.org/python.git
+ $ git clone -b v1 https://git.python.org/python.git
$ cd python
$ git checkout --track origin/master
When you do an initial clone like this::
- $ git clone -b v1 http://git.python.org/python.git
+ $ git clone -b v1 https://git.python.org/python.git
-git clones remote repository ``http://git.python.org/python.git`` to
+git clones remote repository ``https://git.python.org/python.git`` to
directory ``python``, creates a remote named ``origin``, creates
remote-tracking branches, creates a local branch ``v1``, configure it
to track upstream remotes/origin/v1 branch and checks out ``v1`` into
the working directory.
+
Updating local and remote-tracking branches
-------------------------------------------
Don't move tags with ``git tag -f`` or remove tags with ``git tag -d``
after they have been published.
+
Private information
'''''''''''''''''''
Whatever you do, don't panic. Almost anything in git can be undone.
+
git checkout: restore file's content
------------------------------------
(Do not use ``git checkout`` to view a content of a file in a commit,
use ``git cat-file -p``; e.g. ``git cat-file -p HEAD~:path/to/README``).
+
git reset: remove (non-pushed) commits
--------------------------------------
difference very clearly. Bare repositories don't have indices or
working trees so in a bare repo only soft reset is possible.
+
Unstaging
'''''''''
<https://git-scm.com/book/en/Git-Basics-Undoing-Things>`_ for details
about unstaging and other undo tricks.
+
git reflog: reference log
-------------------------
$ git cherry-pick save-master~ save-master
$ git branch -D save-master # remove temporary branch
+
git revert: revert a commit
---------------------------
of merge. See the discussion `How to revert a faulty merge
<https://www.kernel.org/pub/software/scm/git/docs/howto/revert-a-faulty-merge.html>`_.
+
One thing that cannot be undone
-------------------------------
grep -Oless`` - in the latter case ``git grep`` passes ``+/pattern``
option to less.
+
bash/zsh completion
-------------------
Git-for-windows comes with git-bash for which bash completion is
installed and enabled.
+
bash/zsh prompt
---------------
be configured to allow access with great granularity; gitolite has a
lot of documentation.

+Web interface to browse repositories can be created using `gitweb
+<https://git.kernel.org/cgit/git/git.git/tree/gitweb>`_ and `cgit
+<http://git.zx2c4.com/cgit/about/>`_. Both are CGI scripts (written in
+Perl and C). In addition to web interface both provide read-only dumb
+http access for git (http(s):// URLs).
-https://git.kernel.org/cgit/git/git.git/tree/gitweb
+There are also more advanced web-based development environments that
+include ability to manage users, groups and projects; private, group
+and public repositories; and often include issue trackers, wiki pages,
+pull requests and other tools for development and communication. Among
+these environments are `Kallithea <https://kallithea-scm.org/>`_ and
+`pagure <https://pagure.io/>`_, both are written in Python; pagure was
+written by Fedora developers and is being used to develop some Fedora
+projects. `Gogs <http://gogs.io/>`_ is written in Go; there is a fork
+`Gitea <http://gitea.io/>`_.
-http://git.zx2c4.com/cgit/about/
+And last but not least `Gitlab <https://about.gitlab.com/>`_. It's
+perhaps the most advanced git web-based development environment.

+From Mercurial to git
+=====================
-https://about.gitlab.com/
+There are many tools to convert Mercurial repositories to git. The
+most famous are, perhaps, `hg-git <https://hg-git.github.io/>`_ and
+`fast-export <http://repo.or.cz/w/fast-export.git>`_ (many years ago
+it was known under the name ``hg2git``).
+But a better tool, perhaps the best, is `git-remote-hg
+<https://github.com/felipec/git-remote-hg>`_. It provides transparent
+bidirectional access (pull and push) to Mercurial repositories from
+git. The author wrote a `comparison of alternatives
+<https://github.com/felipec/git/wiki/Comparison-of-git-remote-hg-alternatives>`_
+that seems to be mostly unbiased.
-From Mercurial to git
-=====================
+To use git-remote-hg, install or clone it, add to your PATH (or copy
+script ``git-remote-hg`` to a directory that's already in PATH) and
+prepend ``hg::`` to Mercurial URLs. For example::
-Mercurial for Git users https://mercurial.selenic.com/wiki/GitConcepts
+ $ git clone https://github.com/felipec/git-remote-hg.git
+ $ PATH=$PATH:"`pwd`"/git-remote-hg
+ $ git clone hg::https://hg.python.org/peps/ PEPs
-https://github.com/felipec/git-remote-hg
+To work with the repository just use normal ``git fetch/pull/push``
+commands.
