opencode-choose-directory

Windows-only OpenCode V2 TUI plugin that adds a 选择目录 button to the home screen.

The button opens the native Windows Explorer-style folder picker. Selecting a directory keeps OpenCode on the home screen; OpenCode creates the session in that directory only after the first prompt is submitted.

Features

• Visible only on the OpenCode home screen
• Positioned at the far right of the home footer
• Native Windows IFileDialog folder picker
• Explorer-style address bar, search, navigation tree, and folder list
• Preserves the selected directory until the first prompt is submitted
• Does not create an empty session when a directory is selected
• No keyboard shortcut, command-palette entry, or slash command
• Handles spaces, Chinese characters, and other Unicode paths

Requirements

• Windows 10 or Windows 11
• OpenCode V2
• Windows PowerShell 5.1 (included with Windows)

Install

npm (recommended)

Install the latest version from npm and add it to the global OpenCode configuration:

opencode2 plugin add opencode-choose-directory

Restart opencode2 after installation.

To install a specific version:

opencode2 plugin add [email protected]

The package is available at npmjs.com/package/opencode-choose-directory.

Manual configuration

You can also add the npm package directly to ~/.config/opencode/cli.json:

{
  "plugins": [
    "opencode-choose-directory@latest"
  ]
}

Preserve any existing entries in plugins, then restart opencode2.

GitHub source installation

To run the plugin directly from source, clone the repository into your OpenCode configuration directory:

git clone https://github.com/huahai0202/opencode-choose-directory.git `
  "$HOME\.config\opencode\plugins\opencode-choose-directory"
Set-Location "$HOME\.config\opencode\plugins\opencode-choose-directory"
npm install

Add the cloned TUI entrypoint to ~/.config/opencode/cli.json. Replace <USER> with your Windows user name:

{
  "plugins": [
    "file:///C:/Users/<USER>/.config/opencode/plugins/opencode-choose-directory/src/tui.tsx"
  ]
}

Update and uninstall

Install the newest npm release:

opencode2 plugin add opencode-choose-directory@latest

Remove the plugin from the global configuration:

opencode2 plugin remove opencode-choose-directory

How It Works

1. The plugin appends a button to the outer prompt.footer TUI slot so it stays at the far right.
2. The slot input supplies sessionID; the button renders only when it is absent.
3. Clicking the button launches hidden Windows PowerShell in STA mode.
4. PowerShell creates the native IFileDialog COM picker with FOS_PICKFOLDERS.
5. The selected path is returned as UTF-8 Base64 between fixed markers.
6. The plugin resolves the path through OpenCode and preloads the location-scoped agent/model catalogs.
7. The plugin restores focus to the home prompt after the native dialog closes.
8. OpenCode creates a session in that location when the first prompt is submitted.

Development

npm install
npm run typecheck

The main implementation is in src/tui.tsx. src/index.ts is the package entrypoint and declares that the package has a TUI plugin.

Limitations

• Windows only. The plugin does not register a button on other platforms.
• The native folder picker resembles File Explorer but does not include the full Explorer tab bar or file-operation toolbar.
• The OpenCode V2 plugin API is beta and may require compatibility updates.
