Arya Language

Write .arya programs with JavaScript/npm libraries and a Python function bridge. This local experimental extension candidate is 1.3.4 and includes the 1.3.0-alpha.9 compiler. Neither candidate is published. The published Marketplace extension 1.3.2 bundles language 1.3.0-alpha.7. Compiler and extension versions are separate; arya editor status reports both for the new candidate.

Features include:

• Syntax highlighting, semantic colors, snippets, completion, hover, and outline.
• Syntax, lexical name, constant-write, and optional static-type diagnostics.
• Lexical go-to-definition, open-document references, guarded rename, and signature help.
• Rename refuses exported-symbol changes when unopened callers cannot be covered.
• Document formatting, spelling Quick Fixes, and standard-library member hints.
• Arya: Run File, Arya: Check File, and Arya: Stop File commands.
• Arya Dark, Arya Light, Arya File Icons, and an editor setup walkthrough.

use python "math" as math

fn greet(name: string): string {
  return "Hello, " + name
}

print(greet("Arya"), math.sqrt(81))

Run Arya: Editor Setup Guide after installation. Arya: Enable File Icons selects the included icon set; Arya: Choose Color Theme opens the theme chooser. Arya: Open Editor Tour opens an unsaved sample. Existing icon themes may override the language icon. Appearance preferences change only when you choose a theme or run the icon command.

Node.js 22.15 or newer must be available for Run File and Check File. The compiler is included, so these commands need no global Arya installation. Set aryaLanguage.nodePath if Node is outside the editor's PATH, and aryaLanguage.pythonPath for an optional Python interpreter. Python is required only by programs that import Python modules. Dependencies are installed separately.

Run and Check require workspace trust and save the file first. Editing diagnostics and highlighting remain available in Restricted Mode. Editor analysis does not execute your imports. Optional static checking has bounded inference; external npm/Python APIs remain unknown unless described by declarations. See the debugging guide for source maps and current debugging limits.

The companion works independently of AryaCode. In AryaCode, built-in diagnostics and execution controls remain in charge, while the companion supplies appearance and semantic tokens. AryaCode pins its embedded compiler separately; installing this extension does not update that compiler.

For offline installation, install arya-language@1.3.0-alpha.7, then run npx --no-install arya editor install. arya editor path reports its bundled VSIX. See the editor guide and business APIs and tools.
