• ✅ Keywords, types, functions, strings, numbers, operators
• ✅ Support for comments (// and /* */)
• ✅ import keyword highlighting
• ✅ Custom icon for .wave files
• ✅ Run Wave button → wavec run <file> (native Windows and optional WSL)
• ✅ Diagnostics and parser errors
• ✅ Completion and signature help
• ✅ Hover and go to definition
• ✅ Clickable import("module"); paths and missing-import diagnostics

How to Use

1. Install this extension
2. Open any .wave file
3. Press ▶ Run Wave at the top of the file to run it

Requirements

• wavec compiler must be installed and available in your PATH
• wave-agape must be available in PATH, configured with wave.languageServer.path, or bundled under server/<platform>-<architecture>/wave-agape (.exe on Windows)

Windows uses native wavec.exe and wave-agape.exe by default. WSL remains an opt-in compatibility mode through wave.compiler.useWsl and wave.languageServer.useWsl.

Development

npm install
npm run compile

Marketplace automation

Pushing a version tag such as v0.3.0 runs .github/workflows/marketplace.yml. The workflow bundles x64 Linux and Windows servers plus x64 and Apple Silicon macOS servers, uploads the VSIX as an Actions artifact, and publishes it to the VS Code Marketplace when the VSCE_PAT repository secret is set.

The language-server source defaults to wavefnd/wave-agape at v0.2.0. Set the WAVE_AGAPE_REPOSITORY and WAVE_AGAPE_REF repository variables to use a different repository or a pinned tag/commit.

Wave imports follow the compiler's resolution rules. std::io::format resolves under ~/.wave/lib/wave/std, while package::module resolves through wave.imports.dependencyRoots or the explicit wave.imports.dependencies mapping. Relative paths in these settings are resolved from the workspace.
