Ticket #16778 (closed enhancement: fixed)
cairo @1.8.0 requesting a +no_quartz variant

Description
Could a +no_quartz variant be added to the cairo port, please? The Quartz backend causes problems for me with Hebrew text. By the look of it, Quartz has some built-in bidirectional support that screws things up.
I guess there is a slight chance this is related to #15626. Even if it isn't related, the users experiencing the deficiency of that ticket may benefit from such a variant, too.
A simple patch that adds the variant is attached.
To make the problem go away, one must activate cairo with +no_quartz and then recompile pango (I do port -vf deactivate cairo, port -vf install cairo +no_quartz, port -vf uninstall pango @1.22.0_0, port -vf install pango). I guess this means pango must link against cairo statically. Is there any chance of changing that, too? I would open a second ticket, but I believe the maintainer is the same, so perhaps just a comment here will suffice.
The problem is demonstrated in the attached pictures, which show a GTK2 GUI version of Vim displaying the attached text file with :set rightleft wrap linebreak. My suspicion that it is to do with bidi is substantiated by the fact that portions of the lines seem to be simply reversed in the consonant-only text (the part at the bottom without all the dots).

Please file a separate issue against pango for that, or better yet, file a bug report with the developers of Pango. I don't think I would know what to do to fix it.

OK, I'll try to do that when I have a moment: check it isn't just a configure flag and then nag the Pango guys about it. Same with the actual text rendering bug: I'll try to report that to the cairo folks. This ticket can just be about adding a no_quartz variant as a workaround/option.

- Status changed from new to closed
- Resolution set to fixed
- Port changed from cairo to cairo, cairo-devel, pango, pango-devel
The problem is fixed, slightly differently than you suggested: in r47716 I moved Quartz support in cairo and pango to a +quartz variant which is off by default, giving you your no-quartz option.
