This shows an example of submitting patches to MUSHclient using Git.

First, install git. ;)

Then, get a copy of the MUSHclient source, like this:


$ git clone git://github.com/nickgammon/mushclient.git

If you already have MUSHclient from git, make sure you have the latest version, like this:


$ git pull     # from the mushclient directory

Change to the MUSHclient directory, and make a branch for your changes:


$ cd mushclient
$ git checkout -b my_extra_stuff

Switched to a new branch "my_extra_stuff"

Edit the code. In my case I added a line in doc.cpp, line 724, as follows:


  Note (Translate ("MUSHclient - FreeWare MUD client."));

See what changes you made:


$ git status

# On branch my_extra_stuff
# Changed but not updated:
#   (use "git add <file>..." to update what will be committed)
#
#       modified:   doc.cpp
#
no changes added to commit (use "git add" and/or "git commit -a")

Compile and test that things are working how you expect.

Then, add and commit the changes:


$ git commit -am "Added extra welcome message"

Created commit d3a7ec4: Added extra welcome message
 1 files changed, 1 insertions(+), 0 deletions(-)

Make a patch file:


$ git format-patch master --stdout > my_great_patch.diff

Check out the patch:


$ cat my_great_patch.diff

The patch can now be emailed to me, or posted in the forum.

To make your code more readable please use [code] tags as described here.

If posting in the forum, make sure you "escape forum codes" as well as using the 'code' tag as described in the link above.

If I choose to accept the patch, I can use "git am" to "apply mail message" which would merge the patch into the latest version.

Another, possibly easier method is to use GitHub's inbuilt fork support. You have to install git, as well as have a public repository of your own somewhere (and I'll explain how to fork using GitHub in particular).

There are a few guides you might want to read beforehand, or in addition to this one:

(EDIT: Actually, this one guide gets you started really well, so you might want to see this one first if you're a github newbie. It assumes msysgit, but it's still largely relevant for Cygwin's git too: http://github.com/guides/using-git-and-github-for-the-windows-for-newbies)

Tutorials on general git usage: http://learn.github.com/
Setting up an SSH key so you can push to your GitHub repository: http://help.github.com/msysgit-key-setup/
Configuring git: http://help.github.com/msysgit-key-setup/
Forking with GitHub: http://help.github.com/forking/

Pretty much everything at http://help.github.com/ and http://github.com/guides/home will be useful. Also, note that this is just a simple overview of collaborating with GitHub; it assumes you have at least a working knowledge of git itself, and preferrably have your GitHub account set up (which the above links should help with).

1. Go to http://github.com/nickgammon/mushclient, and click "Fork" near the upper-right side of the page (below the search bar).

2. Run the following commands from the console/terminal (taken from GitHub's help article on the topic) to clone your forked GitHub repository to your computer, and set up a 'remote' so you can easily push your changes to your GitHub fork later. Make sure that you're in the directory you want the repository folder to go into, i.e. if you want the directory to be in Documents\mushclient\, you should be in the Documents\ folder.

git clone git@github.com:<Your GitHub username here>/mushclient.git

cd mushclient

git remote add origin git://github.com/<Your GitHub username here>/github-services.git

git fetch origin

3. Edit the source, do what you want, etc etc. 'git diff' is a great command to use to see what you've changed exactly, and 'git status' shows which files have been modified/added/removed.

5. When you're ready to make your changes public, make sure you've committed your changes, and use 'git push origin master'. You'll probably need to enter your GitHub password at this point.

6. Once you're ready for Nick to look over your changes, click "Pull request" on your forked GitHub repository and fill out the form.

If in doubt, consult the tutorials/documentation. I'm definitely not a GitHub expert. ;)
