This PR expands oxfmt’s LSP formatting support to treat additional non-file:// document URIs as “in-memory” documents (instead of only handling file:// and untitled://), and extends the test suite/snapshots to cover new schemes.

Pull request overview

This PR expands oxfmt’s LSP formatting support to treat additional non-file:// document URIs as “in-memory” documents (instead of only handling file:// and untitled://), and extends the test suite/snapshots to cover new schemes.

Changes:

  • Update the formatter’s LSP URI handling to branch on uri.scheme() == "file" and treat all other schemes as in-memory.
  • Rename/clarify the “unsaved document” test group to “in-memory document” and add new scheme test cases (vscode-userdata://, ccsettings://).
  • Regenerate/extend snapshot outputs for the new test cases.
