Tiny diffs using difflib's SequenceMatcher

Project description

Do you have textual (or binary) data that you need to patch?

` >>> a = 'you say yes, i say no' >>> b = 'you say stop, and i say go go go' `

But you want a smaller patchfile than what difflib’s unified_diff() creates?

` >>> diff = '\n'.join(difflib.unified_diff(a, b)) >>> len(diff) 137 `

mini_patch also uses difflib’s SequenceMatcher machinery, but it creates tiny, ASCII-encoded patches:

` >>> patch = mini_patch.make_mini_patch(a.encode('utf-8'), b.encode('utf-8')) >>> patch '0!d:8,2;i:11,$4$dG9w;i:12,$8$IGFuZA==;r:19,1,$4$Zw==;i:21,$8$IGdvIGdv;' >>> len(patch) 70 `
