Revert "Proposed expandable hover API" by gabritto · Pull Request #61132 · microsoft/TypeScript

Gabriela Araujo Britto (gabritto) · 2025-02-06T19:10:47Z

Reverts #59940.

We merged it just to enable internal testing of the prototype implementation, so I'm reverting this for 5.8 RC, and a polished version should go in for 5.9.

This reverts commit 80eeb4e.

Thanks for the PR! It looks like you've changed the TSServer protocol in some way. Please ensure that any changes here don't break consumers of the current TSServer API. For some extra review, we'll ping Sheetal Nandi (@sheetalkamat), Matt Bierner (@mjbvz), Kat Marchán (@zkat), and Joaquin Jares (@joj) for you. Feel free to loop in other consumers/maintainers if necessary.

Looks like you're introducing a change to the public API surface area. If this includes breaking changes, please document them on our wiki's API Breaking Changes page.

Also, please make sure Daniel Rosenwasser (@DanielRosenwasser) and Ryan Cavanaugh (@RyanCavanaugh) are aware of the changes, just as a heads up.

Does VS Code need to know to not send this request anymore, or will it "just work" because the extra data will be ignored?

Does VS Code need to know to not send this request anymore, or will it "just work" because the extra data will be ignored?

Good question, I'll double check.

Matt Bierner (mjbvz) · 2025-02-07T20:12:50Z

Gabriela Araujo Britto (@gabritto) On the VS Code side we gate our check to TS 5.7 , not specific pre-release version (plus you need the setting enabled). If you're planning to remove this, can you update VS Code to only send this request on TS 5.9+

Matt Bierner (@mjbvz) should I temporarily remove the whole feature from the vscode side as well? I could update it to only send the request for TS 5.9+, but in theory, we'll ship TS 5.9 nightly versions starting next week, and I won't bring this back into TSServer time for that. On the same vein, I'd also have to remove the setting.
