Bring the CodeMirror file editor up to the same rich highlighting as the Shiki
file view, so toggling edit <-> view is visually consistent. lezer collapses far
more tokens than TextMate (import/from/const are all "keyword"), so a theme
remap can't reach parity — instead, project real Shiki tokens onto decorations.
- Worker: add highlightTokens — tokenize with an arbitrary registered TextMate
theme and return per-line styled runs with offsets. The theme object ships to
the worker once per name; later calls send only the name.
- New shikiHighlight CodeMirror extension: a StateField of mark decorations
built from worker tokens. Re-tokenizes on a short idle (off the keystroke
path) and maps decorations through edits so colors persist while typing.
- flexokiTheme: add { syntaxColors: false } to keep only the editor UI theme,
so the lezer highlighter doesn't compete with the Shiki decorations.
- FilesView: enable Shiki highlighting (same language resolver as the file view
→ identical language) and drop lezer token colors when it's active. lezer
language stays on for indentation/folding/brackets.
