ttorii20 · 2024-06-05T00:30:44Z

This PR addresses an issue with TextPainter's caret position calculation for text containing full-width spaces. Currently, the caret position is not accurately calculated for strings with full-width spaces. To resolve this, the following changes have been made:

Corrected the logic for caret position calculation when full-width spaces are present in the text.
Added and updated test cases to ensure accurate caret position calculation.
These changes ensure that the caret position for text with full-width spaces is computed correctly.

This issue was introduced by the commit a0a854a.

LGTM.

The whole trailing space check thing is a hack and we should expose the width of a line with trailing spaces instead. But that will be a riskier fix to cherry-pick to the beta / stable channel (if you intend to do so).

I looked at the SkParagraph code and it looks like the statement here about it treating only " " and "\t" as spaces is not true. It's using code unit properties. Could you update or delete that first paragraph?

nit: could you use \u{3000} to make it more obvious (or add a comment) that there is a trailing fullwidth space after A?

nit: move this to the "caret" test group?

LGTM 👍

But seconding the nits left by @LongCatIsLooong .

Nit: Too many newlines here, there should only be one.

Hi @LongCatIsLooong @justinmc

Thank you both for your review!

I have completed the requested changes:

Updated the SkParagraph white space handling comments.
Merged the trailing full-width space test into the existing caret test.
Please review the latest commit.

LongCatIsLooong

Could you delete the sentence that says "SkParagraph currently treats " ", "\t", and "\u{3000}" as white spaces."? (since it's still a bit misleading as SkParagraph treats a wider range of codepoints as spaces when doing line breaking).
