I love the idea of yi and decided to try to make a syntax-based highlighting mode for it. I started with HTML since that should be easy; my efforts are on github:
https://github.com/travitch/yi/blob/html-mode/yi/src/library/Yi/Syntax/HTML.hs I plan on setting up tag matching to highlight badly-nested tags, but right now the parser only produces a list of open tags, close tags, text nodes, and comment nodes. It works fine and looks great for small files, but anything large chokes it. By "chokes", I mean that enabling the mode and running 'yi /tmp/test.html' on a file with more than a few dozen lines pegs a CPU for longer than I've had the patience to wait (it also starts allocating all of my memory). Are there any guidelines I should follow to make an efficient syntax-based mode? I don't really understand the incremental parser, but I feel like re-parsing the file each time might be more efficient than what I am seeing. I also notice this same behavior with the Javascript mode (which isn't surprising, since my mode looks very similar). The "clever" haskell mode seems much more resilient to large files, but I don't see any huge differences. -- -- Yi development mailing list yi-devel@googlegroups.com http://groups.google.com/group/yi-devel --- You received this message because you are subscribed to the Google Groups "yi.devel" group.
