Description

This PR resolves #37 by adding support for installing the OpenCode VS Code extension (sst-dev.opencode) in code-server, aligning it with the existing code-claude, code-codex, and code-vibe options.

Changes

  • agent-vm.setup.sh: Added INSTALL_CODE_OPENCODE and HAS_OPENCODE toggles; installs sst-dev.opencode when code-server extensions are installed.
  • internal/cli/setup.go: Registered code-opencode in software list, help text, preinstall flag parser, and interactive setup wizard extension options.
  • internal/cli/setup_test.go: Added unit test coverage for --preinstall=code-opencode and the setup wizard extension prompt.
  • tests/setup-script.sh: Updated shell test suite for HAS_OPENCODE and 4-extension installations.
  • Docs & i18n: Updated CHANGELOG.md, en.ts, and fr.ts dictionaries.

Closes #37.

Summary by CodeRabbit

  • New Features

📝 Walkthrough

The setup CLI, wizard, web preinstall lists, and changelog now support OpenCode as a code-server extension. The setup script installs and tracks OpenCode for standalone and extension selections. Tests cover the new option and installation paths.

The CLI, wizard, web preinstall lists, and changelog include code-opencode. The CLI enables opencode and code-server when the option is selected. Tests cover preinstall parsing and wizard selection.
Install and track the extension
agent-vm.setup.sh, tests/setup-script.sh
The setup script recognizes OpenCode in standalone or extension mode, installs sst-dev.opencode, and uses HAS_OPENCODE for MCP configuration and agent detection. Shell tests cover OpenCode detection and extension installation.

Explanation

Issue [#37] requests installation of the sst-dev.opencode VS Code extension by using the existing extension mechanism. agent-vm.setup.sh adds the extension toggle and installation path. internal/cli/setup.go exposes code-opencode for software selection, preinstall parsing, and the setup wizard. The unit and shell tests cover the new option and installation behavior. The implementation also keeps the required OpenCode CLI selection for extension-only setup.

Full details: Out of Scope Changes check

Explanation

The changed files support issue [#37]. Shell changes implement extension selection and installation. CLI changes expose the option and its required CLI dependency. Tests validate the behavior. Changelog and translation changes document the option. No unrelated change is established.

Comment thread internal/cli/setup.go Outdated
Keep OpenCode CLI selected when extension is chosen, since sst-dev.opencode requires the CLI binary. Update setup help, wizard choice prompt, tests, and documentation accordingly.

Assert the OpenCode-specific wizard prompt.

The OpenCode scenario selects the extension-only branch, but it asserts only the exported choices. Add an assertion for Extension only (OpenCode keeps the CLI, required by its extension) so a regression to the generic prompt is detected.

Hi @sylvinus,

This pull request is ready for review to address #37.

Here is a quick overview of the implementation:

Extension Integration: Added code-opencode to support installing the official OpenCode VS Code extension (sst-dev.opencode) in code-server, bringing parity with code-claude, code-codex, and code-vibe.
Architecture Alignment: Because sst-dev.opencode serves as an IDE bridge to the underlying CLI tool rather than bundling an embedded runtime, the setup workflow ensures the OpenCode CLI and its environment are retained when the extension is selected.
Configuration and MCP: Configured HAS_OPENCODE handling in agent-vm.setup.sh to register MCP servers (such as Chrome DevTools) into OpenCode's configuration.
Testing and Documentation: Added unit test cases covering --preinstall=code-opencode and interactive wizard flows in internal/cli/setup_test.go, updated shell test assertions in tests/setup-script.sh, and updated the documentation in CHANGELOG.md, en.ts, and fr.ts.

All unit tests and CodeRabbit review checks are passing cleanly. Please let me know if you would like any adjustments.
