This adds the ability to drag the label on an arrow to a different location within the line segment/arc. https://github.com/tldraw/tldraw/assets/469604/dbd2ee35-bebc-48d6-b8ee-fcf12ce91fa5 - A lot of the complexity lay in ensuring a fixed distance from the ends of the arrowheads. - I added a new type of handle `text-adjust` that makes the text box the very handle itself. - I added a `ARROW_HANDLES` enum - we should use more enums! - The bulk of the changes are in ArrowShapeUtil — check that out in particular obviously :) Along the way, I tried to improve a couple spots as I touched them: - added some more documentation to Vec.ts because some of the functions in there were obscure/new to me. (at least the naming, hah) - added `getPointOnCircle` which was being done in a couple places independently and refactored those places. ### Questions - the `getPointOnCircle` API changed. Is this considered breaking and/or should I leave the signature the same? Wasn't sure if it was a big deal or not. - I made `labelPosition` in the schema always but I guess it could have been optional? Lemme know if there's a preference. - Any feedback on tests? Happy to expand those if necessary. ### Change Type - [ ] `patch` — Bug fix - [x] `minor` — New feature - [ ] `major` — Breaking change - [ ] `dependencies` — Changes to package dependencies[^1] - [ ] `documentation` — Changes to the documentation only[^2] - [ ] `tests` — Changes to any test code only[^2] - [ ] `internal` — Any other changes that don't affect the published package[^2] - [ ] I don't know [^1]: publishes a `patch` release, for devDependencies use `internal` [^2]: will not publish a new version ### Test Plan 1. For arrow in [straightArrow, curvedArrow] test the following: a. Label in the middle b. Label at both ends of the arrow c. Test arrows in different directions d. Rotating the endpoints and seeing that the label stays at the end of the arrow at a fixed width. e. Test different stroke widths. f. Test with different arrowheads. 2. Also, test arcs that are more circle like than arc-like. - [x] Unit Tests - [ ] End to end tests ### Release Notes - Adds ability to change label position on arrows. --------- Co-authored-by: Steve Ruiz <steveruizok@gmail.com> Co-authored-by: alex <alex@dytry.ch> |
