RE: Dillo in Debian

by devidfil＠gmail.com

Hi, I'm the current dillo Debian maintainer. I know, dillo 2.0 isn't in Debian right now but it isn't caused by me, fltk2 package is missing in Debian so I can't upload the 2.0 version right now. However I've done the fltk2 package for Debian and if all is ok it will uploaded (and accepted) in Debian as soon as possible (but it won't be in Lenny). If you will switch dillo to fltk1.3 then the problem will be the same because actually Debian doesn't have the 1.3 version of fltk (only 1.1) so I will need to work on a new package for fltk1.3 and this will require time (there is no a good documentation about how to work on a static lib package). So please continue to use fltk2. I'm sorry for the delay. Devid Antonio Filoni

IMG ratio

by jcid＠dillo.org

Hi Johannes, Now that I have the image process mostly in my head, I'd like to hook correct image ratio scaling when only one of width/height is given. I see scaling done with the styleengine in a_Html_add_new_image but 'props' goes away when popping the tag. How do I handle this? Do I have to preserve props in the stack until I have the final data, or is there another way? Please explain. -- Cheers Jorge.-

Dillo in Debian

by akemnade＠tzi.de

Hi, a status update: I just got a notice from the official dillo package maintainer that fltk2 will be added to debian. So I think the chances for dillo 2.0 to go into debian (not lenny) will be good. Greetings Andreas Kemnade

Dillo in Debian

by jcid＠dillo.org

Hi Wookey, A post in dillo-dev made me aware of this thread: http://bugs.debian.org/cgi-bin/bugreport.cgi?archive=no&bug=510348 Thanks for your comment ;-) Some technical facts (all available from dillo.org) * dillo-0.8.x is unmaintained * dillo-2.x is the official stable branch * dillo-2.x uses FLTK2 not GTK2 as stated in the thread IMHO it'd be good to have dillo-0.8.x in Lenny, at least until dillo-2.x makes its way into Debian. We've been working on this branch for more than a year and it's way better than the former (details in the website). I'm aware of the problem distros have with including statically linked packages, and it looks like dillo-2.x will be left out of them until this issue is solved. Unfortunately FLTK-2.0 is stalled and an official release of it is nowhere near in the future. OTOH, an active set of developers is pushing FLTK-1.3.x very fast. This branch provides more or less the same FLTK-2.0 does. It's being actively developed, is less buggy and more stable, and will most probably be released soon (I'm yet to ask the team about dates). At some point in time we'll be migrating to FLTK-1.3.x (it has almost the same API), and hopefully then it'll be easier to include dillo in Debian. If you make progress with the certificate patch, please let us know. We're fully devoted to CSS now, and have no SSL expert in the team :( -- On a personal level, I'd love to have Dillo used in Debian as a help browser. This is, since a long time ago I've noticed applications come with almost no help (F1 button in the old days) and help drives you to an "About" window. But OTOH they have very good HTML docs (usually in usr/share/), that could provide for accurate context-sensitive help pages. The problem is they don't hook a web browser to the help button because a bloated app. that takes a long time to start, only to crawl the computer afterwards, is the last thing a developer hopes as her end user experience. There's the possibility of having a simple API to remote control the browser so the same instance is used. Dillo is fast, lean, and low on library dependencies. Any doubts, just don't hesitate to ask. -- Cheers Jorge.-

dillo about to be dropped from debian

by r00t＠constancy.org

FYI: http://bugs.debian.org/cgi-bin/bugreport.cgi?archive=no&bug=510348 it seems that dillo is about to be dropped from debian, because * ssl lacks proper certificate verification * it still uses gtk1.2 (personally, the first never bothered me, and i consider the second a _feature_) Greetings, Thorben Thuermer
