Prima for Visual Studio Code
Language support for Prima, a
symbol-first scientific computing language.
v0.1 scope: this first release is purely client-side — syntax highlighting,
a .pra file icon, language configuration (comments, brackets, auto-closing,
indentation), and snippets. A language server (diagnostics, go-to-definition,
hover, completion) will land in later releases.
Features
- Syntax highlighting — a full TextMate grammar (
source.prima) covering:
- keywords and reserved words (
let, fn, class, match, parfor,
config, import, async/trait, try/catch, ...);
- the numeric tower and container types (
Integer, Rational, Number,
F64, I8..U128, Array<T>, Result<A, B>, Fn(...) -> T, ...);
- string family:
"...", '...', raw r"..."/r'...', f-strings
f"..."/f'...'/rf"..." (with {expr} interpolation), and TeX literals
tex"...";
- number literals (decimal,
0x/0o/0b, floats);
- operators including
^, @/@., ../..=, :=, ->/=>, ∪/∩;
- annotations
@builtin, @jit, @gpu, @parallel, @c_api::extern;
- comments:
/// docs, //! module docs, //, /* */.
- File icon — a lightweight Prima Icons theme (File icon theme → Prima
Icons) gives
.pra files the Prima mark; everything else keeps the default
icon set.
- Language configuration —
// / /* */ comments, bracket
auto-closing/surrounding, and { / } indentation rules.
- Snippets —
fn, class, for, while, if/if-else, match,
import, config, parfor, println, and more.
Install
- From the VS Code Marketplace
(once published): search Prima.
- From a
.vsix: code --install-extension prima-lang-0.1.0.vsix.
Usage
Open any .pra file (or set the language to Prima). The .pra extension is
registered automatically; to use the custom file icon, select Prima Icons in
the command palette (Preferences: File Icon Theme).
Development
npm install
npm run compile # tsc -> out/
npm run package # vsce package -> prima-lang-*.vsix
npm test # @vscode/test-electron suite (headless; xvfb-run -a npm test on Linux CI)
CI (.github/workflows/ci.yml) compiles, runs the test suite, and packages a
.vsix on every push and PR.
Roadmap
- Language server protocol client +
prima-backed server (diagnostics via
prima check, hover from stdlib docs, completion, go-to-definition).
prima fmt on save.
