What are the most popular languages that have used an AST walker for their implementation? I know Ruby used to do this, but there must be others. (I'm interested in the lowest PL speed that users will tolerate if you have awesome features.)

Interested in trying difftastic, but don't want to compile it yourself? I now have GitHub releases with prebuilt binaries for Linux, macOS and Windows for you to play with!

I've often found reading diffs tricky when I have to scroll up to see what file I'm in, then back down to the changes I'm interested in. In difftastic, I'm experimenting with printing the file name on every hunk displayed.
