Research direction

Start by tracing the line fragment renderer and how selected ranges are queried during each render loop. The feature is done when invisible characters appear only within selected text while remaining hidden elsewhere, and profiling confirms selected-range checks are negligible.

Description

enhancement
Description

Some editors allow users to only see invisible characters in their selected text. Right now, CETV can only enable them for the entire document, or not at all.

Alternatives Considered

No response

Additional Context

Some updated requirements:

  • The line fragment renderer will need to know about selected ranges, this introduces an interesting dependency tree.
  • Querying selected ranges may be slow when it's done for every visible line fragment each render loop. The implementation should consider this or profile it to make sure it's negligible.
