Typing in larger files is way too slow because of syntax highlighting lexer speed. about idea-multimarkdown

[vsch]

Did a test with syntax highlighting using a plain text lexer. Typing issues resolved and Psi parsing is not affected. This means that doing syntax highlighting with external annotator will do the trick and will not affect typing speed like the current implementation does.

Temporary fix added option into preferences to turn off syntax highlighting. Annotations remain but this allows faster typing when in creative mode vs validation mode.

The issue is now less severe with threading issues addressed. I will be implementing an external annotator which delays syntax highlighting until a later update phase. It will also allow more complex, layered attributes that lexer based syntax highlighting does not handle.

I will have to make the two syntax highlighting methods as options because only lexer based highlighting works in preferences color settings.

External annotator based syntax highlighting is now the defeault.

[vsch]

• minimize updates to unchanged parts of the paragraph or table

• handle IDE skipping calls to handlers when fast typing (or rolling forehead on the
  keyboard).

• HTML generation was not disabled when only main editor was shown. This would cause

• Changed default syntax highlighter to external annotator based to reduce typing delay. If
  you want to use lexer based syntax highlighting you will need to change it in
  settings/preferences.

  Fastest typing response is achieved when:

  • syntax highlighting is turned off
  • wrap on typing is disabled
  • auto-format tables is disabled
  • all previews are turned off
