Question: combining Twoslash with diff fences to show patch + tooltips #403

Hello! We are moving feature requests and support questions to discussions and using issues only for bugs to help better track those going forward. See you in the Discussions tab!

Hey @schickling I am a Maintainer of the expressive-code-twoslash project.

Twoslash's core function is to run a TypeScript language server against a single, self-contained code sample and use special comments (e.g., // ^^^ for highlighting, // @errors for error checking, // ---cut--- to hide code) to generate metadata about that specific snippet. It is not designed to work directly on code diffs (comparisons between two different files or versions of code), and passing any data not supported by Twoslash will cause a processing error (As you've likely already ran into)

Given this information, the only solution would be a custom plugin that could take the source data and construct the EC annotations based on provided data similar to what EC-Twoslash is doing under the hood with the Twoslash and Typescript engines (converting from Typescript compiler data into Twoslash annotation then into EC compatible annotations)
