Hi,
I noticed recently that the nightly builds started wrapping non-monospaced long before the line hits the soft wrap column or window frame.
To reproduce: 1. Make a new document 2. Type lorem<tab> to get the lorem ipsum snippet 3. Open View->Font->Show Fonts 4. Select a monospaced font like Courier 5. Select View->Enable Soft Wrap 6. Select View->Wrap Column->Use Window Frame 7. Resize the width of the window and note how the text wraps by the window frame 8. In the font panel, change to a non-monospace font like Helvetica 9. Resize the width of the window and note how the text wraps a good bit before the window frame
Expected result is that step 9 behaves like step 7.
After a little bit of sleuthing I think the relevant commit is https://github.com/textmate/textmate/commit/f487c5d57585f98d16273e0fa63b8a3d...
The character used to calculate column width changed from m to n, which doesn’t matter for monospaced fonts, but for non-monospaced fonts it can be quite a difference.
Would it be possible to change back to n?
Although this can have the opposite effect of the line sometimes overshooting the window frame by a tiny bit before soft wrapping. To fully fix this you would have to calculate the soft wrap width of each individual line, but I presume that that is quite a big change and could present speed issues with large files.
Cheers and thank you for TextMate, Kim
