GitHub's compare view is available at:
https://github.com/$USER/$REPO/compare/$REV_A...$REV_B
Naturally, $USER
and $REPO
are the owner (user/organization) and repository names, respectively.
$REV{A,B}
are the two sides of the compare view; they can either be a ref in $USER
's repository, i.e. the name of a branch, tag or a commit SHA, or it can be a ref in $OWNER
's fork of the repository by using the format $OWNER:$REF
.
You can get a diff or patch for the result of the compare view by appending .diff
or .patch
to the URL, respectively.
