git is a fast version control system that lets you collaborate on a project. For details on how to use git, go and read the git tutorial. For details on the public git repository, please check it here.
The homepage of the Worg project is here: http://orgmode.org/w/worg.git. You can get a read-only clone of the repository with the command:
~$ git clone git://orgmode.org/worg.git
Since Worg is constantly updated you may want to update your copy of Worg
before reading sometimes later. To do so
cd into the Worg directory and
upgrade your copy of Worg with the command:
~$ git pull
If you want to contribute to Worg, keep reading.
:PROPERTIES: :CUSTOM_ID: contribute-to-worg :END:
giton your system.
~$ git clone firstname.lastname@example.org:worg.git
If you already have your local clone of Worg obtained via http protocol, you can easily tell your git to remain using
httpfor fetching and
gitfor pushing, by adding to your =~/.gitconfig=:[url "git://email@example.com:worg.git"] pushInsteadOf = http://repo.or.cz/r/
which could come handy later on for any project you clone from http://repo.or.cz
- Go to the newly created
worg/directory and edit some files.
- If you created files, add them to the git index:~$ git add *.org
- Commit changes with the appropriate comment:~$ git commit -a -m "summary comment about all changes"
- Push your change to Worg:~$ git push
The second time you contribute to Worg
- Go to your
- Be sure to "pull" the last version of the repository.~$ git pull --rebase
- Make some changes. (If you want to learn more about various gitworkflow, read [[file:worg-git-advanced.org][this page]].)
- Commit your changes on your local repository:~$ git commit -a -m "summary comment about all changes"
~$ git push
- Push your change on the remote repository
The Worg TODO file is
worg-todo.org. If you are a Worg zealot, maybe you want to add this file to the list of your agenda files. For example, here is my
org-agenda-filesvariable:(setq org-agenda-files '("~/org/bzg.org" "~/git/worg/worg-todo.org")
I have an agenda custom command for checking tasks that are assigned to me:(org-add-agenda-custom-command '("W" tags "Owner=\"Bastien\""))
The next time someone assigns a task for me, it will appear in my Worg agenda view.
Register your changes under your name
Information regarding your name can be stored in your global =~/.gitconfig= file, or in
Edit it like this:[user] name = FirstName LastName email = firstname.lastname@example.org
Now your changes will be filed under your name.
Rebase to avoid merging commits
It's good practice to pull the current version of the repository before making your own additions. But even if you do, someone might make a change while you are working. So it will often be necessary to pull immediately before pushing your new commit. In this situation, if you use =git pull= directly, then a 'merge commit' will be generated, looking like this:
commit aaaabbbbbbbbbaaaaaaaaabbbbbbbb Merge: bababa efefefef Author: Some one Date: Wed Nov 24 00:00:01 2010 -0700
Merge branch 'master' of git+ssh://repo.or.cz/srv/git/Worg
That's not a major problem, but it's nice to keep the commit logs free of this stuff. To avoid generating the merge commit, use the
--rebaseoption when pulling:~$ git pull --rebase
Basically this means that your commit will be put to the top of the stack, as if no one had made any additions while you were working. More advanced git users might make their changes in a personal branch, and then rebase that branch against a freshly pulled master branch before merging it in to master. The end result would be the same as pulling with
Dealing with line endings
Unix, Windows and Mac all have different conventions for marking the end of a line. This might lead to problems when editing the same file across platforms. Github advises Linux users to automatically convert all external files to LF on committing (see http://help.github.com/dealing-with-lineendings) by setting:~$ git config --global core.autocrlf input
For Worg, this is the wrong solution, since there are already files with both end of line conventions in the repository. Instead tell git locally not to convert files by setting:~$ git config core.autocrlf false
Of course you have to be careful not to save Windows files as Unix files or vice versa, since this would lead to large and confusing diffs. This should not be a problem with Worg as
Emacs's VC supports many common git operations, but others, like
repository syncing must be done from the command line. For example
C-x v v does check in changes in the local and not
in the remote repository in contrast to other back ends like svn.
It is necessary to do additionally
~$ git push
to sync the change on the remote server.
