The sympy git server is at https://github.com/sympy/sympy . The main Sympy repository may be cloned with git clone git://github.com/sympy/sympy.git.

The first and the most important thing is that you should understand that git is different. For example it uses staging area (so called index) for iteratively preparing commits. This and other great and unique features of git make it the preference of many developers, so go read its documentation!

• git project page: https://git-scm.com/
• git faq explaining many things: https://git.wiki.kernel.org/index.php/GitFaq

  make sure to read mails referenced from the faq -- they are really brilliant, e.g. Linus on git and renames

• git wiki: https://git.wiki.kernel.org/index.php/Main_Page
• git documentation: https://git-scm.com/doc

Here is a nice cheatsheet which will probably make your life easier in the beginning: https://jan-krueger.net/development/git-cheat-sheet-extended-edition

Being said all this, now comes a simplified mapping between hg commands and git commands. Use it with care -- there are some semantic differences ...

---

If you know how to use hg very well and just looking at how to do the same things in git, this page is right for you. Use it like a dictionary hg -> git. Some equivalent git commands may seem more complex than the corresponding hg counterparts; that‘s because the natural flow of work in git doesn‘t map 1:1 to Mercurial. But the point here is that if you are used to some specific workflow in hg, it can be directly translated to git using the table below and it does exactly the same thing as you are expecting it to.

When editing this wiki page, please only add an exact equivalent to some hg command; a full explanation can always be found somewhere else on the net.

Tips

 - use gitk to visualize history (much more capable than "hg vi")
 - use git gui to visually stage/unstage what you are preparing for commit
   to index (it too can work on hunk-by-hunk basis)
 - git stash is your friend
 - git rebase --interactive is your friend too :)
 - windows users: either use cygwin or msysgit:
   https://code.google.com/p/msysgit/

 - don‘t try to project your usual habits - open your mind, and maybe you‘ll
   discover much more superior workflow. (yes, this needs hard work and RTFM,
   and being ready that FM sometimes differ from what software actually does)
 - Add this

 parse_git_branch() {
   git branch 2> /dev/null | sed -e ‘/^[^*]/d‘ -e ‘s/* \(.*\)/(\1)/‘
   # __git_ps1 "(%s)"
   # use the second line instead if you have bash autocompletion for git enabled
 }
 PS1="\w\$(parse_git_branch) $ "

   to your promptstring to show current branch when in a git-tracked directory.

git -> hg conversion

You can use this script:

#! /bin/bash

work=`mktemp -t -d sym.XXX`
git format-patch -k -p -o $work master..HEAD
# add a new line after the subject line so that Mercurial imports it fine.
sed -i ‘4a\\‘ $work/*
cd ~/repos/sympy.hg/
hg import $work/*
rm -r $work

to convert all patches between master..HEAD to mercurial repository sitting at ~/repos/sympy.hg/.

Alternatively, you could use the hg-git Mercurial plugin.

how to checkout remote branch

Start with some repository, for example create a new one from scratch:

$ mkdir sympy
$ cd sympy
$ git init

or clone our official repository:

$ git clone git://git.sympy.org/sympy.git
$ cd sympy

Now let‘s say you want to checkout some branch from git://github.com/certik/sympy.git. The canonical way is to add it to your remotes:

$ git remote add ondrej git://github.com/certik/sympy.git

Then fetch all branches from there into your remote branches:

$ git fetch ondrej

You can now list them with "git branch -r", or examine them with "git log ondrej/some_branch". Finally, to checkout the mpmath5 branch, do:

$ git checkout -b mpmath5 ondrej/mpmath5
