hIDE and Visual Haskell use the ghc lexer and get near-instantaneous syntax highlighting.
Hmm... I just installed Visual Haskell 0.1, and when I type in the editor, CPU usage rises to about 70% and there's a noticeable delay before each character appears on the screen. This is a very short module (~100 lines) and a Pentium M 1600 CPU. Am I doing something wrong?
I can't say too much about the internals of VH since I've not see the code, only the description. Perhaps that's because they're starting the parser immediately after every keystroke and/or not killing the parser when the user types another key. I've been using hIDE on a Pentium M 1600 laptop and on the size of modules I've tried so far it's quick. The syntax highlighting updates immediately and the type checker shows up errors a second or so after I stop typing (which is because we wait about that long before starting the parser). Duncan
