All the hidden and not hidden features of GitHub. Taken from Zach Holmans talk at Aloha Ruby Conference 2012.
Adding ?w=1 to any diff URL will remove any changes only in whitespace, enabling you to see only that code that has changed.
When cloning a repo the .git can be left off the edge.
$ git clone https://github.com/tiimgreen/github-cheat-sheetHub is a command line tool that wraps git in order to extend it with extra features and commands that make working with GitHub easier.
This allows you to do things like:
$ hub clone tiimgreen/tocWhich translates to:
$ git clone git://github.com/tiimgreen/toc.gitTo move to the previous directory in the command line:
$ cd -Similarly, to move to the last branch in git:
$ git checkout -
# Switched to branch 'master'git.io is a simple URL shortener for GitHub.
Gists are an easy way to work with small bits of code without creating a fully fledged repo.
Gists are also full repos so can be cloned like any other:
$ git clone https://gist.github.com/tiimgreen/10545817
When on a repo page keyboard shortcuts allow you to navigate easily.
Pressing t will bring up a file explorer.
Pressing w will bring up the branch selector.
Pressing s will select the search bar.
To see all of the shortcuts for given page type shift+?
If a particular commit fixes an issue, any of the keywords fix/fixes/fixed or close/closes/closed, followed by the issue number, will close the issue.
$ git commit -m "Fix cock up, fixes #12"If you want to link to another issue in the same repo, simple type hash # then the issue number, it will be auto-linked.
To link to an issue in another repo, user_name/repo_name#ISSUE_NUMBER e.g. tiimgreen/toc#12.
To add syntax highlighting to code in README:
require 'tabbit'
table = Tabbit.new('Name', 'Email')
table.add_row('Tim Green', 'tiimgreen@gmail.com')
puts table.to_sTo view all commits on a repo by author add ?author=username to the URL.
https://github.com/rails/rails/commits/master?author=dhh
Commits can be pushed with no code changes by adding --allow-empty
$ git commit -m "Big-ass commit" --allow-empty
In GitHub to compare branches, the URL will look something like this:
https://github.com/user/repo/compare/{range}
Where {range} = master...4-1-stable
e.g.:
https://github.com/rails/rails/compare/master...4-1-stable
{range} can be changed to things like:
https://github.com/rails/rails/compare/master@{1.day.ago}...master
https://github.com/rails/rails/compare/master@{2014-10-04}...master
which allows you to see the difference on the master branch up to one day ago.
Adding #L52 to the end of a code file URL will highlight that line number.
It also works with ranges, e.g. #L53-L60:
https://github.com/rails/rails/blob/master/activemodel/lib/active_model.rb#L53-L60
