Editor Support

Syntax highlighting for .nr files ships in the repository under neuro-language-support/. There is no Language Server yet; that is Phase 8 in the Quick Roadmap.

VS Code

cd neuro-language-support
npm install -g @vscode/vsce      # once
vsce package                     # -> neuro-language-support-<version>.vsix
code --install-extension neuro-language-support-*.vsix --force

Reload the window afterwards (Developer: Reload Window). A grammar change does not reach editors that are already open.

Working on the grammar

Symlink the folder into ~/.vscode/extensions/ instead of repackaging on every edit; a window reload then picks up each change.

The grammar and the lexer must agree on the keyword set. That is not a convention, it is a test: compiler/lexical-analysis/tests/tmlanguage_sync.rs fails when a keyword is added to one and not the other.

Other editors

The grammar is a standard TextMate .tmLanguage.json file, so any editor that reads TextMate grammars (Sublime Text, Zed, the Monaco-based editors) can load it directly from neuro-language-support/syntaxes/.
