unicode combining chars and PRE
by eocene＠gmx.com April 3, 2015

April 3, 2015

Looking at http://doc.rust-lang.org/1.0.0-beta/book/more-strings.html#indexing-strings and I see that dillo doesn't like combining characters in PRE. Small example attached.

Documentation fixes
by onepoint＠starurchin.org March 12, 2015

March 12, 2015

I have four documentation patches ready for review that came from looking at the doxygen error output. The first is the upgrade to Doxyfile, the other three are small fixes to errors that doxygen happened to notice. I hope the extended descriptions will make everything clear. http://starurchin.org/dillo/patch/doxygen-upgrade-config.html http://starurchin.org/dillo/patch/doxygen-remove-unmatched-close-div.html http://starurchin.org/dillo/patch/doxygen-typo-nsbp-entity.html http://starurchin.org/dillo/patch/doxygen-escape-button-tag-angle-brackets.… There is more to do but I'd like to clear these out of the way first. All comments are welcome. Regards, Jeremy Henty

Problem with page positioning.
by johnfound＠asm32.info March 6, 2015

March 6, 2015

Hi all. It is my first post on this mailing list. I want to use Dillo as a HTML help browser for my program. I need it, because it has faster startup time and this is very important for a help system, where the user presses F1 and expects the help to open instantly. (What is not the case with all other browsers). Anyway, the problem I have is that when starting Dillo with URL that contains local anchor ID, it first positions properly, but short time later, (when the CSS get loaded?) it repositions the page and the needed element moves somewhere else, very far from the current page position. Example that can be tested: http://fresh.flatassembler.net/index.cgi?page=content/articles/2_FreshLibDo… Once the page is loaded (on the wrong position), pressing Ctrl+R or clicking on "Reload" button, repositions the page to the proper position. Is this problem can be easily solved? I can try to fix it by myself, but my C/C++ skills are very low and then I will need some assistance. Best Regards and thanks for the great browser. -- http://fresh.flatassembler.net http://asm32.info John Found <johnfound at asm32.info>

Dillo documentation delivered daily
by onepoint＠starurchin.org March 4, 2015

March 4, 2015

My website is up again[1] and I have added a daily build of the Dillo documentation (having noticed that the version on the Dillo site is over a year old). HTML: http://starurchin.org/dillo/doc/html/index.html tarball: http://starurchin.org/dillo/doc/dillo-doc.tar.gz (Note that the tarball has moved from its old location.) Doxygen generates quite a few errors when building the docs. I would like to fix them (if only to have less noise from my cron jobs). Would the Dillo devs be interested in the patches? Regards Jeremy Henty [1] Nginx spontaneously decided not to run until I tweaked its configuration. No idea why, but at least it is fixed.

Core-dump pasting from one form field into another
by james.from.wellington＠gmail.com Feb. 2, 2015

Feb. 2, 2015

Hello All, This is exercisable in Dillo 3.0.4.1, but not new. I found it by accident in my hack-up of Dillo 3.0.4. The reproduction is: - enable cookies for .google.com - navigate to https://mail.google.com/mail/?ui=html - fight the links until you get a screen with two fields, one for the username and one for the password - type something into the username field - select it and drag to the password field -- core dump I am on: - OSX 10.6.8 - Dillo 3.0.4.1 with SSL enabled - FLTK 1.3.3 - with dpid, etc from Dillo 3.0.4 with extensive hacking so the fault could be Mac-specific. Essentially the same fault (in Fl::dnd()) is reproducible in clean Dillo 3.0.4, with FLTK 1.3.2, clean dpid, etc, so I *think* it's not a product of my hackery. Clean Dillo 3.0.4 does not report the CGContextSetShouldAntialias and related errors, so I *think* that they are unrelated. Some errors and backtrace below. So far, I have not reproduced this fault in the FLTK input test program. Does anyone have a favourite piece of form html for me to try, to see if we can get out of needing gmail for the reproduction.

an interlaced gif doesn't finish drawing

I've consistently noticed that the image in the upper left corner of http://forum.thinkpads.com doesn't finish drawing initially. If I isolate the image or click to a second page, it'll show the whole thing properly.
