[Enhancement] Improve performance, when huge block of code is edited #10

Open subhamayd2 opened 3 years ago

subhamayd2 commented 3 years ago

When I am editing a huge block of code, the editor feels a bit sluggish. This is probably happening because on each change, the whole block of code is being parsed for highlighting. Is there any way that can improve the performance? I was thinking, if the parsing can be debounced somehow, that might improve the performance.

Yep, we could also perform local highlighting, since most of the time local changes don't affect the rest of the document!

Agreed. Something like, only parsing the line that is currently being edited.

Any improvement on this? Looks like we have same situation until now.
