So far, all of the people trying difftastic with huge files have been using C or C++ source code. Maybe it's more common in those communities? (Difftastic will eventually fall back to fast, dumb, line-based diffing if you give it a multi-megabyte source file.)

Difftastic 0.20 is out! * Better handling of nesting changes, based on autochrome. This fixes some nasty corner cases (Python screenshot) and gives nicer results in general (Scala screenshot). * Better handling of large files, even multi-megabyte!

tree-sitter is wonderful, but it struggles if you try to parse its own output files. In fairness, parsing a multi-megabyte C file is hard. The C# parser has a parser.c file totalling 18MiB!
