My second talk at LCA2013 – the first one accepted – was on “wiggle”, my tool for applying patches that don’t apply. In the presentation I wanted to explain how “diff” works – as I then wanted to explain why one of the things that wiggle does is more complex that a simple “diff”. For this I came up with a simple animation that I presented as a series of “impress” slides. Some suggested I make them into an animated “gif”, so I did. And here it is (click for a higher-res version):
Among the useful feedback I got about wiggle:
- UTF-8 support would be good. This only applies to the way it breaks strings into words. Currently it only understand ASCII
- Detecting patterns of “replace A with B” and looking for unreplaced copies of “A” in the original might be useful.
The slides in LibreOffice format are here and the recording of the talk is here
