It works fine on the development system. It looks like an FLTK font handling problem. This thread may help: http://lists.auriga.wearlab.de/pipermail/dillo-dev/2010-June/007523.html -- Cheers Jorge.-

Hi, I'm creating a new distro that is supposed to be fast and light. I thought about Firefox but it all stacks up after you install gtk as well. So your slogan "fast and light" seemed sound the ticket. I compiled it on my ubuntu 10.04 system and it works on there. Copied it to the new distro and here is the output when I type "dillo" at the prompt: dillo: /lib/libjpeg.so.8: no version information available (required by dillo) paths: Cannot open file '/root/.dillo/dillorc' paths: Using /usr/local/etc/dillo/dillorc paths: Cannot open file '/root/.dillo/keysrc' paths: Using /usr/local/etc/dillo/keysrc dillo_dns_init: Here we go!

Segmentation fault I can't get a backtrace from GDB because it's supposed to be a mega minimal system. It works fine on the development system. Regards, James

Commit bit: WAS Re: [Dillo-dev] [patch]: html.cc: re-indent Html_tag_open_q() for consistency

I have considered asking but it's been a long while since I have felt comfortable making a serious long-term commitment to working on dillo. I'm very happy to contribute as and when I can but I wouldn't want anyone expecting me to be active, say, in six month's time. Also, I don't feel I know what the long-term plan for dillo is, in terms of priorities and directions. My impression (perhaps wrongly) is that the discussion happens elsewhere (although it does surface on this list every now and then). So I wouldn't feel comfortable doing non-trivial stuff without the other dev's review. But maybe that's over-cautious. If everyone's time would be more effectively used if I had a commit bit then I'm happy to have one. I feel a bit one-of-a-kind in the Dillo world. Is there anyone else in the class of "not a core dev but a long-time contributor"? Regards, Jeremy Henty

The wise say you shouldn't sweat the small stuff, but when one function in a file is indented by 4 spaces and all the rest are indented by 3, well... Regards, Jeremy Henty

Please review carefully - I am not familiar with the Dillo CSS implementation so this is really a request for comments. (Although it does fix the page that first highlighted the problem.) And thanks for the explanation of the CSS workings! Regards, Jeremy Henty

All Html_tag_open_*() functions that don't add a widget (e.g. a textblock or an image) must call html->styleEngine->inheritBackgroundColor() to make background-color work. Unfortunately this is just a hack that doesn't solve all problems. E.g. <pre style="border: 1px solid black">foo</pre> will still not work. For now, I would just add inheritBackgroundColor() where necessary. > > Also, I wonder if more of the Html_tag_open_*() functions should call > html->styleEngine->setNonCssHints(), but I don't understand the CSS > engine well enough to be sure. setNonCssHints() in contrast is not a hack :-) It is used to pass style information from (deprecated) non-CSS HTML attributes like bgColor, align and so on to StyleEngine. This style information from HTML attributes has to be handled specially as described in http://www.w3.org/TR/CSS2/cascade.html#preshint So for all HTML-attributes that we want to support and that change the style there should be a corresponding setNonCssHints() call.

[bug]: <pre> element respects color but not background-color

by onepoint＠starurchin.org

The problem is that Html_tag_open_pre() does not call html->styleEngine->inheritBackgroundColor() before calling HT2TB(html)->addParbreak(). But several other Html_tag_open_*() functions have the same problem, eg. Html_tag_open_{dt,dl}(). Should we fix them one by one or is there a better way? Also, I wonder if more of the Html_tag_open_*() functions should call html->styleEngine->setNonCssHints(), but I don't understand the CSS engine well enough to be sure. Regards, Jeremy Henty
