Test CJK support

[khaledhosny]

We need someone to test CJK support and report what is working and what is broken, test files would be great as well.

[khaledhosny]

@luzpaz do you know anyone who can work here, or do you at least have test documents from old Scribus issues?

[luzpaz]

@ftake ping

[ftake]

Has the latest code been merged into trunk? Or should I test the master branch of this repository?

[luzpaz]

@ftake please test the CTL branch: https://github.com/HOST-Oman/scribus/tree/ctl.git
Thanks!

[luzpaz]

BTW, it requires harfbuzz

[luzpaz]

I've been searching old scribus issues and i'm pretty amazed of the lack of test documents.

[ftake]

I get ready for testing: https://build.opensuse.org/package/show/home:ftake:scribus:CTL/scribus

[ftake]

I can not continue testing because scribus is killed with out of memory on my laptop.

As long as I tested quickly, there is problem with auto line break of CJK text.

[khaledhosny]

@ftake providing test documents would be nice, especially for things that works on trunk (before or after boxes merge).

[ftake]

Please use this:

OK, I see problems with line breaking indeed. I’m unable to edit any frames in this document, any idea why?

[luzpaz]

Is that the CJK bug that doesn't allow editing text frames unless it in the Story Editor?

[khaledhosny]

I can’t do almost anything with the file, not even selecting the frame or right clicking on them. Also almost all menu items are disabled.

Hi, thanks for your works. Initially, I want to test and fetched the source, well then I found I have to get libs that's beyond my current knowledge -=- Looks like ftake is more capable of this task over me, and he would help.

Also I've been away from scribus for a couple of years, missing many updates and qt5 libs.
Maybe after system upgrade, these libs will become available and I will come back.

@khaledhosny you need to exit from preview mode either from eye icon in the tool bar or from
view->preview->previewmode

[luzpaz]

Here is the bug i was looking for: 13612 No input method preedit when one inputs CJ text directly into a text frame

[khaledhosny]

@khaledhosny you need to exit from preview mode either from eye icon in the tool bar or from

Yes, that was it.

[khaledhosny]

Here is the bug i was looking for: 13612

I suspect this issues is fixed or mostly fixed, but I need clear instructions on how to reproduce it since I don’t usually use any input methods.

[khaledhosny]

OK, I think I found the root of the issue. I think (for some reason) we are repeatedly applying the CJK spacing adjustments to the same glyph. This seems to be the same underlying issue as https://bugs.scribus.net/view.php?id=13895, but the fix in trunk does not work with CTL code so we need a different strategy to fix it.

[luzpaz]

@jiero what OS/platform are you on ?

[jiero]

Currently on Ubuntu 15.10 GNOME, planed to move to 16.04 GNOME after
release. Okay, I will try to install it sooner with daily builds. And then
I think proper QT5 libs can be found on the newer repository.

Going to do the upgrade tonight.

Another test file: https://bugs.scribus.net/view.php?id=7610 (See attached)

[khaledhosny]

CJK spacing should be better now, there are still differences that I need to investigate.

This doc
cjk-linebreaking.sla.gz
for test CJK line breaking

[khaledhosny]

After merging #162, I think all obvious CJK issues are fixed. I’m closing this now and if new issues are found they should be reported separately.
