This page currently lists a few git settings that I've found useful on my 'hack. These are from the perspective of a beginner with git who was trying to make it comfy to use. I'm hoping that an experienced git user may add anything else that's nifty or important.

Levels of settings & how to change them

git has three levels of settings: system-wide, per-user, and per-repo. All the examples given below are per-user, which is probably the most useful on dreamhacks. git refers to per-user settings as "global".

Settings can be viewed or set with the git config command.

You can use git config --list to see the settings that you have at present.

Recommended settings

To add your username and email to commits:

git config --global user.name=???
git config --global user.email=???

where the ???s should be replaced with a username and email address. It is probably good practice to make this the same email address that you use for bugzilla.

To avoid having to type in your github username and password every time you push something,

git config --global credential.helper=cache

This will cache your details for 15 minutes so that you will not have to enter them again during that time.

To put a number of git command-line commands' output into colour, to make them more readable:

git config --global color.branch=auto
git config --global color.diff=auto
git config --global color.status=auto
git config --global color.ui=auto

To set your preferred text editor (used for writing commit notes):

git config --global core.editor=nano

(change nano to the text editor of your choice)

Excluding files from git

You can tell git to ignore certain files and pay them no attention. For instance, I use vim as my main text editor, and vim creates .swp files all over the place to indicate when it has a file open. Whenever they appeared, git was warning me that these were "untracked files". To resolve this:

  • Create a file in your home directory called .gitignore_global.
  • In this file, specify the types of files to ignore. For example, mine simply says "*.swp".
  • Then do
    git config --global core.excludesfile=/dreamhack/home/????/.gitignore_global
    , substituting your actual home directory for ????.
