Josh Spicer dc5a5460f4 ChatSessionCustomizationProvider testing fixes (#308071)
* Delete individual hooks instead of entire hooks file

When deleting a hook from the Chat Customizations UI, parse the hook
item ID to identify the specific entry within the JSON file. Remove
only that entry and write the file back, instead of deleting the
entire hooks file. If no hooks remain after removal, the file is
deleted.

Also passes the item ID through the action context so the delete
handler can distinguish individual hook entries from whole files.

Fixes microsoft/vscode-internalbacklog#7381

* Throw CancellationError when plugin trust dialog is declined

When the user cancels the trust dialog during plugin installation,
throw a CancellationError instead of silently returning. This allows
the install button's catch handler to properly reset to 'Install'
state instead of incorrectly showing 'Installed'.

Fixes microsoft/vscode-internalbacklog#7378

* Check installed state when rendering marketplace plugin items

When rendering marketplace plugin items in the plugin list, check
whether the plugin is already installed by comparing install URIs
with the agent plugin service's plugin list. Show 'Installed' with
the button disabled instead of offering a redundant install option.

Fixes microsoft/vscode-internalbacklog#7379

* Replace floppy disk icon with newFile icon for create plugin button

The save/floppy disk icon is misleading for a create action. Use the
newFile codicon instead, which better communicates the intent and is
consistent with other create actions in the UI.

Fixes microsoft/vscode-internalbacklog#7373

* Fix plugin page CSS: padding, back button, and focus outlines

- Add padding-bottom to marketplace plugin footer for proper Install
  button alignment (fixes #7377)
- Restyle back-to-installed link as a button with muted foreground
  color and rounded hover background instead of link styling
  (fixes #7384)
- Add outline-offset: -1px to button group buttons to prevent focus
  outline clipping by parent container (fixes #7385)

Fixes microsoft/vscode-internalbacklog#7377
Fixes microsoft/vscode-internalbacklog#7384
Fixes microsoft/vscode-internalbacklog#7385

* Show workspace folder name in provider path for multi-root workspaces

When rendering items from external customization providers (e.g.
Copilot CLI), use the label service to produce workspace-relative
paths for file: URIs instead of bare filenames. This shows the
folder name (e.g. 'tankgame • AGENTS.md') in multi-root workspaces,
matching the core (Local) path behavior.

Visual Studio Code - Open Source ("Code - OSS")

Feature Requests Bugs Gitter

The Repository

This repository ("Code - OSS") is where we (Microsoft) develop the Visual Studio Code product together with the community. Not only do we work on code and issues here, we also publish our roadmap, monthly iteration plans, and our endgame plans. This source code is available to everyone under the standard MIT license.

Visual Studio Code

VS Code in action

Visual Studio Code is a distribution of the Code - OSS repository with Microsoft-specific customizations released under a traditional Microsoft product license.

Visual Studio Code combines the simplicity of a code editor with what developers need for their core edit-build-debug cycle. It provides comprehensive code editing, navigation, and understanding support along with lightweight debugging, a rich extensibility model, and lightweight integration with existing tools.

Visual Studio Code is updated monthly with new features and bug fixes. You can download it for Windows, macOS, and Linux on Visual Studio Code's website. To get the latest releases every day, install the Insiders build.

Contributing

There are many ways in which you can participate in this project, for example:

If you are interested in fixing issues and contributing directly to the code base, please see the document How to Contribute, which covers the following:

Feedback

See our wiki for a description of each of these channels and information on some other available community-driven channels.

Many of the core components and extensions to VS Code live in their own repositories on GitHub. For example, the node debug adapter and the mono debug adapter repositories are separate from each other. For a complete list, please visit the Related Projects page on our wiki.

Bundled Extensions

VS Code includes a set of built-in extensions located in the extensions folder, including grammars and snippets for many languages. Extensions that provide rich language support (inline suggestions, Go to Definition) for a language have the suffix language-features. For example, the json extension provides coloring for JSON and the json-language-features extension provides rich language support for JSON.

Development Container

This repository includes a Visual Studio Code Dev Containers / GitHub Codespaces development container.

  • For Dev Containers, use the Dev Containers: Clone Repository in Container Volume... command which creates a Docker volume for better disk I/O on macOS and Windows.

    • If you already have VS Code and Docker installed, you can also click here to get started. This will cause VS Code to automatically install the Dev Containers extension if needed, clone the source code into a container volume, and spin up a dev container for use.
  • For Codespaces, install the GitHub Codespaces extension in VS Code, and use the Codespaces: Create New Codespace command.

Docker / the Codespace should have at least 4 Cores and 6 GB of RAM (8 GB recommended) to run a full build. See the development container README for more information.

Code of Conduct

This project has adopted the Microsoft Open Source Code of Conduct. For more information see the Code of Conduct FAQ or contact opencode@microsoft.com with any additional questions or comments.
