+ Configure git

+.. _git-config-basic:
+
+Overview
+========
+
+::
+
+  git config --global user.email [e-mail]
+  git config --global user.name "Your Name Comes Here"
+
+
+In detail
+=========
+
+This is to tell git_ who you are, for labeling any changes you make to
+the code.  The simplest way to do this is from the command line::
+
+  git config --global user.email [e-mail]
+  git config --global user.name "Your Name Comes Here"
+
+This will write the settings into your git configuration file - a file
+called ``.gitconfig`` in your home directory. 
+
+Advanced git configuration
+==========================
+
+You might well benefit from some aliases to common commands.
+
+For example, you might well want to be able to shorten ``git checkout`` to ``git co``. 
+
+The easiest way to do this, is to create a ``.gitconfig`` file in your
+home directory, with contents like this::
+
+  [core]
+          editor = emacs
+  [user]
+          email = [e-mail]
+          name = Your Name Comes Here
+  [alias]
+          st = status
+          stat = status
+          co = checkout
+  [color]
+          diff = auto
+          status = true
+
+(of course you'll need to set your email and name, and may want to set
+your editor).  If you prefer, you can do the same thing from the command
+line::
+
+  git config --global core.editor emacs
+  git config --global user.email [e-mail]
+  git config --global user.name "Your Name Comes Here"
+  git config --global alias.st status
+  git config --global alias.stat status
+  git config --global alias.co checkout
+  git config --global color.diff auto
+  git config --global color.status true
+
+These commands will write to your user's git configuration file
+``~/.gitconfig``.
+
+To set up on another computer, you can copy your ``~/.gitconfig`` file,
+or run the commands above.
+
+Other configuration recommended by Yarik
+========================================
+
+In your ``~/.gitconfig`` file alias section::
+
+   wdiff = diff --color-words
+
+so that ``git wdiff`` gives a nicely formatted output of the diff. 
+
+To enforce summaries when doing merges(``~/.gitconfig`` file again)::
+
+   [merge]
+      summary = true

+====================
+Development workflow
+====================
+
+You already have your own forked copy of the ipython_ repository, by
+following :ref:`forking`, :ref:`set-up-fork`, and you have configured
+git_ by following :ref:`configure-git`.
+
+Workflow summary
+================
+
+* Keep your ``master`` branch clean of edits that have not been merged
+  to the main ipython_ development repo.  Your ``master`` then will follow
+  the main ipython_ repository.
+* Start a new *feature branch* for each set of edits that you do.
+* If you can avoid it, try not to merge other branches into your feature
+  branch while you are working.
+* Ask for review!
+
+This way of working really helps to keep work well organized, and in
+keeping history as clear as possible.
+
+See - for example - `linux git workflow`_. 
+
+Making a new feature branch
+===========================
+
+::
+
+   git branch my-new-feature
+   git checkout my-new-feature
+
+Generally, you will want to keep this also on your public github_ fork
+of ipython_.  To do this, you `git push`_ this new branch up to your github_
+repo.  Generally (if you followed the instructions in these pages, and
+by default), git will have a link to your github_ repo, called
+``origin``.  You push up to your own repo on github_ with::
+
+   git push origin my-new-feature
+
+From now on git_ will know that ``my-new-feature`` is related to the
+``my-new-feature`` branch in the github_ repo.
+
+The editing workflow
+====================
+
+Overview
+--------
+
+::
+
+   # hack hack
+   git add my_new_file
+   git commit -am 'NF - some message'
+   git push
+
+In more detail
+--------------
+
+#. Make some changes
+#. See which files have changed with ``git status`` (see `git status`_).
+   You'll see a listing like this one::
+
+     # On branch ny-new-feature
+     # Changed but not updated:
+     #   (use "git add <file>..." to update what will be committed)
+     #   (use "git checkout -- <file>..." to discard changes in working directory)
+     #
+     #	modified:   README
+     #
+     # Untracked files:
+     #   (use "git add <file>..." to include in what will be committed)
+     #
+     #	INSTALL
+     no changes added to commit (use "git add" and/or "git commit -a")
+
+#. Check what the actual changes are with ``git diff`` (`git diff`_).
+#. Add any new files to version control ``git add new_file_name`` (see
+   `git add`_). 
+#. To commit all modified files into the local copy of your repo,, do
+   ``git commit -am 'A commit message'``.  Note the ``-am`` options to
+   ``commit``. The ``m`` flag just signals that you're going to type a
+   message on the command line.  The ``a`` flag - you can just take on
+   faith - or see `why the -a flag?`_. See also the `git commit`_ manual
+   page.
+#. To push the changes up to your forked repo on github_, do a ``git
+   push`` (see `git push`). 
+
+Asking for code review
+======================
+
+#. Go to your repo URL - e.g. ``http://github.com/your-user-name/ipython``.
+#. Click on the *Branch list* button:
+
+   .. image:: branch_list.png
+
+#. Click on the *Compare* button for your feature branch - here ``my-new-feature``:
+
+   .. image:: branch_list_compare.png
+
+#. If asked, select the *base* and *comparison* branch names you want to
+   compare.  Usually these will be ``master`` and ``my-new-feature``
+   (where that is your feature branch name).
+#. At this point you should get a nice summary of the changes.  Copy the
+   URL for this, and post it to the `ipython mailing list`_, asking for
+   review.  The URL will look something like:
+   ``http://github.com/your-user-name/ipython/compare/master...my-new-feature``.
+   There's an example at
+   http://github.com/matthew-brett/nipy/compare/master...find-install-data
+   See: http://github.com/blog/612-introducing-github-compare-view for
+   more detail.
+
+The generated comparison, is between your feature branch
+``my-new-feature``, and the place in ``master`` from which you branched
+``my-new-feature``.  In other words, you can keep updating ``master``
+without interfering with the output from the comparison.  More detail?
+Note the three dots in the URL above (``master...my-new-feature``) and
+see :ref:`dot2-dot3`.
+
+Asking for your changes to be merged with the main repo
+=======================================================
+
+When you are ready to ask for the merge of your code:
+
+#. Go to the URL of your forked repo, say
+   ``http://github.com/your-user-name/ipython.git``.
+#. Click on the 'Pull request' button:
+
+   .. image:: pull_button.png
+
+   Enter a message; we suggest you select only ``ipython`` as the
+   recipient.  The message will go to the `ipython mailing list`_.  Please
+   feel free to add others from the list as you like.
+
+Merging from trunk
+==================
+
+This updates your code from the upstream `ipython github`_  repo. 
+
+Overview
+--------
+
+::
+
+   # go to your master branch
+   git checkout master
+   # pull changes from github
+   git fetch upstream
+   # merge from upstream
+   git merge upstream master
+
+In detail
+---------
+
+We suggest that you do this only for your ``master`` branch, and leave
+your 'feature' branches unmerged, to keep their history as clean as
+possible.  This makes code review easier::
+
+   git checkout master
+
+Make sure you have done :ref:`linking-to-upstream`.
+
+Merge the upstream code into your current development by first pulling
+the upstream repo to a copy on your local machine::
+
+   git fetch upstream
+
+then merging into your current branch::
+
+   git merge upstream/master
+
+Deleting a branch on github_
+============================
+
+::
+
+   git checkout master
+   # delete branch locally
+   git branch -D my-unwanted-branch
+   # delete branch on github
+   git push origin :my-unwanted-branch
+
+(Note the colon ``:`` before ``test-branch``.  See also:
+http://github.com/guides/remove-a-remote-branch
+
+Several people sharing a single repository
+==========================================
+
+If you want to work on some stuff with other people, where you are all
+committing into the same repository, or even the same branch, then just
+share it via github_.
+
+First fork ipython into your account, as from :ref:`forking`.
+
+Then, go to your forked repository github page, say
+``http://github.com/your-user-name/ipython``
+
+Click on the 'Admin' button, and add anyone else to the repo as a
+collaborator:
+
+   .. image:: pull_button.png
+
+Now all those people can do::
+
+    git clone [e-mail]:your-user-name/ipython.git
+
+Remember that links starting with ``git@`` use the ssh protocol and are
+read-write; links starting with ``git://`` are read-only.
+
+Your collaborators can then commit directly into that repo with the
+usual::
+
+     git commit -am 'ENH - much better code'
+     git push origin master # pushes directly into your repo
+
+Exploring your repository
+=========================
+
+To see a graphical representation of the repository branches and
+commits::
+
+   gitk --all
+
+To see a linear list of commits for this branch::
+
+   git log
+
+You can also look at the `network graph visualizer`_ for your github_
+repo.

+========================================

+Thanks to Yarik Halchenko for this explanation.
+
+Imagine a series of commits A, B, C, D...  Imagine that there are two
+branches, *topic* and *master*.  You branched *topic* off *master* when
+*master* was at commit 'E'.  The graph of the commits looks like this::

+
+Then::

+while::
+
+   git diff master...topic
+
+would output just differences in the topic branch (i.e. only A, B, and

+
+The steps are:
+
+* :ref:`install-git`
+* get local copy of the git repository from github_
+* update local copy from time to time
+
+Get the local copy of the code
+==============================
+
+From the command line::
+
+   git clone git://github.com/ipython/ipython.git
+
+You now have a copy of the code tree in the new ``ipython`` directory.
+
+Updating the code
+=================
+
+From time to time you may want to pull down the latest code.  Do this with::
+
+   cd ipython
+   git pull
+
+The tree in ``ipython`` will now have the latest changes from the initial

+working with *ipython*.
+
+This is not a comprehensive git_ reference, it's just a workflow for our

+You want to tell us about it - best of all!

+      git clone git://github.com/ipython/ipython.git
+      cd ipython
+
+#. Make a 'feature branch'.  This will be where you work on your bug

+   copy of the code in the main branch::
+
+      git branch the-fix-im-thinking-of
+      git checkout the-fix-im-thinking-of

+   that you're going to type a message on the command line.  The ``a``
+   flag - you can just take on faith - or see `why the -a flag?`_.
+
+#. When you have finished, check you have committed all your changes::
+
+      git status
+
+#. Finally, make your commits into patches.  You want all the commits
+   since you branched from the ``master`` branch::
+
+      git format-patch -M -C master
+
+   You will now have several files named for the commits::
+
+      0001-BF-added-tests-for-Funny-bug.patch
+      0002-BF-added-fix-for-Funny-bug.patch
+
+   Send these files to the `ipython mailing list`_.
+
+When you are done, to switch back to the main copy of the code, just
+return to the ``master`` branch::
+
+   git checkout master
+
+Moving from patching to development
+===================================
+
+If you find you have done some patches, and you have one or more feature
+branches, you will probably want to switch to development mode.  You can
+do this with the repository you have.
+
+Fork the ipython_ repository on github_ - :ref:`forking`.  Then::
+
+   # checkout and refresh master branch from main repo
+   git checkout master
+   git pull origin master
+   # rename pointer to main repository to 'upstream'
+   git remote rename origin upstream
+   # point your repo to default read / write to your fork on github
+   git remote add origin [e-mail]:your-user-name/ipython.git
+   # push up any branches you've made and want to keep
+   git push origin the-fix-im-thinking-of
+
+Then you can, if you want, follow the :ref:`development-workflow`.

+.. _set-up-fork:
+
+==================
+ Set up your fork
+==================
+
+First you follow the instructions for :ref:`forking`. 
+
+Overview
+========
+
+::
+
+   git clone [e-mail]/your-user-name/ipython.git
+   cd ipython
+   git remote add upstream git://github.com/ipython/ipython.git
+
+In detail
+=========
+
+Clone your fork
+---------------
+
+#. Clone your fork to the local computer with ``git clone
+   [e-mail]:your-user-name/ipython.git``
+#. Investigate.  Change directory to your new repo: ``cd ipython``. Then
+   ``git branch -a`` to show you all branches.  You'll get something
+   like::
+
+      * master
+      remotes/origin/master
+
+   This tells you that you are currently on the ``master`` branch, and
+   that you also have a ``remote`` connection to ``origin/master``.
+   What remote repository is ``remote/origin``? Try ``git remote -v`` to
+   see the URLs for the remote.  They will point to your github_ fork.
+
+   Now you want to connect to the upstream `ipython github`_ repository, so
+   you can merge in changes from trunk.
+
+.. _linking-to-upstream:
+
+Linking your repository to the upstream repo
+--------------------------------------------
+
+::
+
+   cd ipython
+   git remote add upstream git://github.com/ipython/ipython.git
+
+``upstream`` here is just the arbitrary name we're using to refer to the
+main ipython_ repository at `ipython github`_.
+
+Note that we've used ``git://`` for the URL rather than ``git@``.  The
+``git://`` URL is read only.  This means we that we can't accidentally
+(or deliberately) write to the upstream repo, and we are only going to
+use it to merge into our own code.
+
+Just for your own satisfaction, show yourself that you now have a new
+'remote', with ``git remote -v show``, giving you something like::
+
+   upstream	git://github.com/ipython/ipython.git (fetch)
+   upstream	git://github.com/ipython/ipython.git (push)
+   origin	[e-mail]:your-user-name/ipython.git (fetch)

@@ -7,177 +7,20 b' How to contribute to IPython'
 Overview
 ========
 
-IPython development is done using Bazaar [Bazaar]_ and Launchpad [Launchpad]_.
+IPython development is done using Git [Git]_ and Github.com [Github.com]_.
 This makes it easy for people to contribute to the development of IPython.
 There are several ways in which you can join in.
 
-If you have a small change that you want to contribute, you can edit your
-Bazaar checkout of IPython (see below) in-place, and ask Bazaar for the
-differences:
-
-.. code-block:: bash
-
-    $ cd /path/to/your/copy/of/ipython
-    $ bzr diff > my_fixes.diff
-
-This produces a patch file with your fixes, which we can apply to the source
-tree. This file should then be attached to a ticket in our `bug tracker
-<https://bugs.launchpad.net/ipython>`_, indicating what it does.
-
-This model of creating small, self-contained patches works very well and there
-are open source projects that do their entire development this way. However,
-in IPython we have found that for tracking larger changes, making use of
-Bazaar's full capabilities in conjunction with Launchpad's code hosting
-services makes for a much better experience.
-
-Making your own branch of IPython allows you to refine your changes over time,
-track the development of the main team, and propose your own full version of
-the code for others to use and review, with a minimum amount of fuss. The next
-parts of this document will explain how to do this.
-
-Install Bazaar and create a Launchpad account
----------------------------------------------
-
-First make sure you have installed Bazaar (see their `website
-<http://bazaar-vcs.org/>`_). To see that Bazaar is installed and knows about
-you, try the following:
-
-.. code-block:: bash
-
-    $ bzr whoami
-    Joe Coder <[e-mail]>
-
-This should display your name and email. Next, you will want to create an
-account on the `Launchpad website <http://www.launchpad.net>`_ and setup your
-ssh keys. For more information of setting up your ssh keys, see `this link
-<https://help.launchpad.net/YourAccount/CreatingAnSSHKeyPair>`_.
-
-Get the main IPython branch from Launchpad
-------------------------------------------
-
-Now, you can get a copy of the main IPython development branch (we call this
-the "trunk"):
-
-.. code-block:: bash
-
-    $ bzr branch lp:ipython
-
-Create a working branch
------------------------
-
-When working on IPython, you won't actually make edits directly to the
-:file:`lp:ipython` branch. Instead, you will create a separate branch for your
-changes. For now, let's assume you want to do your work in a branch named
-"ipython-mybranch". Create this branch by doing:
-
-.. code-block:: bash
-
-    $ bzr branch ipython ipython-mybranch
-
-When you actually create a branch, you will want to give it a name that
-reflects the nature of the work that you will be doing in it, like
-"install-docs-update".
-
-Make edits in your working branch
----------------------------------
-
-Now you are ready to actually make edits in your :file:`ipython-mybranch`
-branch. Before doing this, it is helpful to install this branch so you can
-test your changes as you work. This is easiest if you have setuptools
-installed. Then, just do:
-
-.. code-block:: bash
-
-    $ cd ipython-mybranch
-    $ python setupegg.py develop
-
-Now, make some changes. After a while, you will want to commit your changes.
-This let's Bazaar know that you like the changes you have made and gives you
-an opportunity to keep a nice record of what you have done. This looks like
-this:
-
-.. code-block:: bash
-
-    $ ...do work in ipython-mybranch...
-    $ bzr commit -m "the commit message goes here"
-
-Please note that since we now don't use an old-style linear ChangeLog (that
-tends to cause problems with distributed version control systems), you should
-ensure that your log messages are reasonably detailed.  Use a docstring-like
-approach in the commit messages (including the second line being left
-*blank*)::
-
-  Single line summary of  changes being committed.
-
-  * more details when warranted ...
-  * including crediting outside contributors if they sent the
-    code/bug/idea!
-
-As you work, you will repeat this edit/commit cycle many times. If you work on
-your branch for a long time, you will also want to get the latest changes from
-the :file:`lp:ipython` branch. This can be done with the following sequence of
-commands:
-
-.. code-block:: bash
-
-    $ ls
-    ipython
-    ipython-mybranch
-    
-    $ cd ipython
-    $ bzr pull
-    $ cd ../ipython-mybranch
-    $ bzr merge ../ipython
-    $ bzr commit -m "Merging changes from trunk"
-
-Post your branch and request a code review
-------------------------------------------
-
-Once you are done with your edits, you should post your branch on Launchpad so
-that other IPython developers can review the changes and help you merge your
-changes into the main development branch. To post your branch on Launchpad,
-do:
-
-.. code-block:: bash
-
-    $ cd ipython-mybranch
-    $ bzr push lp:~yourusername/ipython/ipython-mybranch
-
-Then, go to the `IPython Launchpad site <http://www.launchpad.net/ipython>`_,
-and you should see your branch under the "Code" tab. If you click on your
-branch, you can provide a short description of the branch as well as mark its
-status. Most importantly, you should click the link that reads "Propose for
-merging into another branch". What does this do?
-
-This let's the other IPython developers know that your branch is ready to be
-reviewed and merged into the main development branch. During this review
-process, other developers will give you feedback and help you get your code
-ready to be merged. What types of things will we be looking for:
-
-* All code is documented.  How to document your code is described in 
-  :ref:`this section <documenting-ipython>`.
-* All code has tests.  How to write and run tests is described in 
-  :ref:`this section <testing>`.
-* The entire IPython test suite passes.
-
-You should also provide us with a list of changes that your branch contains.
-See the :ref:`What's new <whatsnew_index>` section of our documentation
-(:file:`docs/source/whatsnew`) for details on the format and content of this.
-
-Once your changes have been reviewed and approved, someone will merge them
-into the main development branch.
-
 
 Merging a branch into trunk
 ===========================
 
 Core developers, who ultimately merge any approved branch (from themselves,
 another developer, or any third-party contribution) will typically use
-:command:`bzr merge` to merge the branch into the trunk and push it to the
-main Launchpad site. There are a number of things to keep in mind when doing
-this, so that the project history is easy to understand in the long
-run, and that generating release notes is as painless and accurate as
-possible.
