Copilot doesn't offer a way of disabling completion inside comments. People have discovered a comical workaround: swearing in the comment!
I've released difftastic 0.59! In this release:
* Fixed a nasty crash on textual files
* Added F# and device tree support
* Improved comment syntax highlighting (especially for Elm)
Diffing comments is surprisingly hard. In difftastic, I'm colouring the whole changed comment, but also underlining the changed words.
This works OK, but punctuation is harder to read (see second image) and sometimes there's code in comments (see third image).
