Highlighting, with the code inside <code lang=ts> highlighted as that language.
Completion for tags (only the ones allowed where you are), attributes, attribute values and the keys and values of a <slide>
block; hover documentation; diagnostics as you type (the same checks as slides check); outline and folding of
sections, rows, columns and code blocks; go to definition from a code id / from to the blocks that share it. Plugin
tags are known too (from deck.json "plugins").
Snippets: cover, cols (text left, code right), code, row, col, step, section, chart, img, … (type the name and Tab).
Auto-closing tags: typing > after <row> inserts </row>.
Live preview: Slides: Open preview to the side (the preview icon in the editor title, Ctrl+K V) runs the dev server for the folder
and shows it beside the editor. It reloads when you save and follows the cursor: it shows the slide, and the section, you are in.
The language server is bundled, so none of it needs anything installed. The preview uses the slides command when it is on the PATH
(npm i -g @geraldserafin/slideit) and npx otherwise.
Development: npm install here, then F5 with this folder open. npm run grammar regenerates the grammar, npm run server bundles the
language server (both run on vsce package).
