Quickly link to a commit in a GitHub message. SHA: followed by the first 7 or so of the commit SHA for that project will be converted into a link. For example, I just dropped:
SHA: 49b5c3a6eb509
which became - SHA: 49b5c3a

When referencing source code in a GitHub project, it’s nice to be able to link to specific lines of a source file. GitHub makes this easy enough. From the main project page (github.com/jquery/jquery), you can browse to a specific file (github.com/jquery/jquery/blob/master/src/css.js) and then click on line numbers to highlight a line, which also sets the URL anchor (blob/master/srs/css.js#L171), and Shift+Click to highlight multiple lines (blob/master/srs/css.js#L171-185).
The only problem is that source files are subject to change, or even be removed, so there’s no guarantee that your link will always point to the correct place. By default, GitHub project pages link to the most current version of the source. A better practice is to link to a specific commit, where the content of source files are not subject to versioning.
To view a GitHub project at a certain commit, click on the tree link in the commit header, or just press t on your keyboard. You can then browse the project files, and link to sources of this commit, i.e. github.com/jquery/jquery/blob/27291ff06ddb655f90a8d1eada71f7ac61499b12/src/css.js#L171-185. Note that the only difference in the URL is changing the branch name master with the commit SHA.
+1 tip from Paul Irish:
plus you only need 4 characters of the SHA in the URL.. it figures it out. i usually truncate to 7ish characters.
Nice: github.com/jquery/jquery/blob/27291ff/src/css.js#L171-185
I’ve been fiddling with a Gollum wiki and found a couple disappointments running locally.
These issues are all bummers considering how slick Jekyll is.
