Code Outline tree provider for Visual Studio Code

Features

Displays a code outline tree in the explorer pane.

To activate find and expand the "Code Outline" section near the bottom of the Explorer tab.

Language Support

For the outline to work, the language support plugins need to support symbol information.

For the outline to form a tree structure, the language support plugins need to report the entire definition range as part of symbol.

See VS Code issue #34968 and language server protocol issue #132 for a discussion.

Here is a list of languages known to work with Code Outline:
