Can you customize code folding?

Question

Is it possible to customize the way code folding works in Visual Studio Code?

I use a common pattern of defining regions of code across a variety of different document

Answer 1

Now, there are three ways to achieve customized folding in a VSCode extension.

1. Can define regex as folding markers in [language-name].configuration.json file. (However, we cannot have much customization with this approach)

{
  "folding": {
    "markers": {
      "start": "starting regex",
      "end": "ending regex"
    }
  }
}

2. Can define a FoldingRangeProvider from the extension side as described in this answer. FoldingRange in vscode package supports folding customization with startLine, endLine, and foldingKind.

3. Can use Language Server support with textDocument/foldingRange. FoldingRange in vscode-languageserver-protocol supports folding customization with startLine, endLine, startCharacter, endCharacter, and foldingKind.
