Installation

clone repo under ~/.vscode/extensions/vscode-capnp.

Testing Locally

Option 1: Debug launch (recommended)

1. Open this folder in VS Code:
2. Press F5 — this launches an Extension Development Host window
3. In the new window, open any .capnp file and verify:
   • Syntax highlighting works (comments with #, keywords, types)
   • Bracket matching works
   • Ctrl+Shift+P → "Generate Capnp ID" inserts an ID at the top

Option 2: Install locally as VSIX

# Install the packaging tool
npm install -g @vscode/vsce

# Package the extension
vsce package

# Install the .vsix file
code --install-extension vscode-capnp-1.1.0.vsix

Then reload VS Code: and test with a .capnp file.

Publishing to VS Code: Marketplace

1. Get a Personal Access Token from Azure DevOps:

   • Go to https://dev.azure.com/xmonader (create org if needed)
   • User Settings → Personal Access Tokens → New Token
   • Set scope to Marketplace > Manage
   • Copy the token

2. Login and publish:

npm install -g @vscode/vsce
vsce login xmonader        # paste your token when prompted
vsce publish

This publishes version 1.1.0 to the marketplace under your existing xmonader publisher.

Publishing to Open VSX (for VSCodium / open-source VS Code:)

npm install -g ovsx
ovsx publish vscode-capnp-1.1.0.vsix -p <your-open-vsx-token>

Get your token at https://open-vsx.org after signing in with GitHub.

Automated Publishing

The project includes GitHub Actions workflows for CI/CD:

CI Workflow (.github/workflows/ci.yml)

Runs on every push and pull request:

• Compiles TypeScript
• Runs tests
• Packages the extension
• Uploads the .vsix as an artifact

Publish Workflow (.github/workflows/publish.yml)

Triggers automatically when you create a GitHub release:

• Publishes to VS Code: Marketplace (requires VSCE_TOKEN secret)
• Publishes to Open VSX (requires OVSX_TOKEN secret)

Setting up secrets:

1. Go to Settings → Secrets and variables → Actions
2. Add VSCE_TOKEN - Your VS Code: Marketplace PAT
3. Add OVSX_TOKEN - Your Open VSX token
