The author of rust-analyzer discussing how language features help or hinder fast IDEs. If you allow `from m import *` you can't analyse files in isolation, and it's even harder in Rust.

Showing lines of context is a remarkably hard problem for a syntactic diff. Line 23 on the right is new, but lines 24 and 25 also map to the same line on the left! Initially I thought this was a bug. It's impossible to show exactly N context lines whilst preserving alignment.

I've released difftastic 0.25! * Added 3 languages (Janet, Lua and Nix), improved parsing for 4 languages, and improved syntax highlighting for 2 languages * Clarified output when even the raw text is unchanged * A ton of bugfixes found by new users :)
