This improves the performance for using
codeToTokens
withincludeExplanation
option enabled.I'm working with a file that is 3k lines long, and getting the tokens with explanations was taking way too much time, around 7 to 9 seconds.
Turns out that the
explainThemeScope
function was redoing a decent amount of work for each token, for each scope, and for each setting, without depending on any of those. So it would be calculated once and reused.Now I get tokens for that file in ~1.5s
Probably could be improved more, but I didn't want to change any logic.
