Markup in a .wrn file highlights but has no tag or attribute completion,
no tag closing, and no tag-level folding: the grammar's embeddedLanguages
mapping only affects tokenization, and VS Code's HTML language service
never runs on these documents.
The design extracts view blocks into a virtual HTML document where
everything outside them is blanked to whitespace of identical length, so
source positions and virtual positions are the same and no mapping table
is needed. Region detection is a tolerant scanner rather than the parser,
because completion fires while the document is mid-edit and unparseable.
Completion merges WRNexus and HTML entries into one list ranked by
sortText, which also fixes an existing bug: the extension and the server
both answer completion on '<' today, so VS Code concatenates two lists.
Two decisions worth review:
- HTML formatting is excluded. formatWrn already formats markup, knows
WRNexus syntax, and would fight a second formatter that is free to
rewrite spacing inside @click={...} and client:visible.
- Only auto-close-on-type is client-side. Linked editing is standard LSP
and lives in the shared server.
