[PATCH 3 of 3] Easy panning with the left mouse button
by darirf＠yahoo.es March 12, 2009

March 12, 2009

Hi! As this is my first post to the list: hello, I'm the one that ported (or broke, depending on your the point of view) dillo 0.8.6 for the iRex iLiad e-book reader; my alias in mobileread.com is Antartica. I've been reading the lists for some time now, but didn't thought I had anything to share yet. But... I agree with Justus in that panning is the easiest method to scroll in embedded devices; the scroll bar is very small and enlarging it wastes too much screen state. For the iliad port of dillo 0.8.6 I did exactly what Justus is proposing of left-button-does-panning (albeit in a hackish way, as I hardcoded that behaviour). For reference, the patch to old dillo 0.8.6 is in: http://projects.mobileread.com/iliad/users/antartica/dillo/dillo-patch-spli… I was actually doing the same for dillo2, but only have it partly-done (see attach). I would love to have Justus code merged in mainline, as it implements that functionality neatly and it would alleviate me from finishing my hack :). Right now I can't test Justus patch, but I had one error to fix in mine: it didn't pan when showing images. Its worth checking if Justus patch have that right. Anyway, you all are doing an excellent job in keeping dillo relevant. It is really a nice piece of work :). Congrats.

Holiday week
by jcid＠dillo.org March 11, 2009

March 11, 2009

Hi there, I happen to be enjoying a much needed holiday week! :-) The plan is to come back around near wednesday 25. In the meanwhile, I leave you with the following issues lurking in my list to be considered. Maybe all of them can be left to the release after 2.1, but maybe not: [ ] https dialog bombing issue. BUG#868 When enabled, multiple https requests to the same site result in dialog bombing. The https dpi is disabled by default in Dillo. Anyway, in Debian, there's a security warning against dillo for not checking certificates (I don't know what version of dillo they use, nor why they enable https.) [ ] Jump to #anchor doesn't work correctly. The idle timeout doesn't work reliably (an old bug). [ ] Implement @import statement in STYLE element. [ ] What will we do with xhtml? FF doesn't validate. BUG#732 This would be interesting to define. (already suggested as discussion material in another thread). [ ] "-fno-rtti -fno-exceptions" gcc: 64KB less. Enabling this switches reduces the binary size. [ ] dpi for "view page source" (it re-uses search capability). Waiting since a long time... [-] BUG#892 prefs bg_color is not working Johannes was working on related things... [ ] META refresh: "instant client-side redirect". [ ] META refresh: URL='<URI>' case. I plan to implement both when I'm back (and to include them in dillo-2.1). BTW, I want to welcome Tim Nieradzik as a new developer and to tell Joao that the bug in the find-text iterator is not that much important. Just focus on something more urgent. -- Cheers Jorge.-

Server-side CSS detection?
by rn214＠cam.ac.uk March 7, 2009

March 7, 2009

Dear All, I've just joined this list, so I hope I'm posting this in the right place. I'm a webmaster, and I want to make sure that my site works properly in all browsers including dillo. However, some of the new code (*) in my site relies on CSS properties such as display:none and does not gracefully degrade. If a browser has no CSS support, the newest stuff breaks in a very ugly manner, whereas most of the CSS I've written to date fails gracefully (we don't really care if some text-colour is wrong). So my question is, how can I detect CSS support server-side? I don't need to know precise details of the CSS-support; I just want a simple yes/no. So Netscape 4.6 would be "yes", whereas Dillo 0.8, and links/lynx/w3m/googlebot would be "no". I don't want to do it by user-agent sniffing, and, if at all possible, I don't want to rely on javascript (there are plenty of people who have CSS-capable browsers with JS turned off). I've had no luck from google, so I thought I'd ask here, as you'll know the best way to do this. Thank you for your help, Regards, Richard (*) for example, I display HTML tooltips like this: span.tool { position: relative; cursor: help; } span.tool span.tip { display: none;} span.tool:hover span.tip { display: block; z-index: 100; position: absolute; top: 1.6em; left: 0; width: auto; padding: 6px; border: #F00;} <span class='tool'>this is the link <span class='tip'>Here is some <b>html</b> for the tooltip </span> </span> i.e. the tool.tip is normally hidden by display:none, but is displayed as result of the hover action. If a browser doesn't support the CSS display:none property, that will render in a very ugly way, with the tooltip contents displayed inline. So I want to have a way to fall-back (server-side) to: <span title='this is the tooltip, without html'>this is the link </span> My intention is to do this server-side, using a session-variable after testing whether the client supports CSS. But how?

Css_next_token() bug
by Johannes.Hofmann＠gmx.de March 6, 2009

March 6, 2009

Hi, can someone (corvid?) please have a look at attached patch that fixes a bug in Css_next_token() (at least I think so). Consider: <div style="font-family: '\''; background-color: red;">foo bar</div> In firefox the background is red, in current dillo not, because the string '\'' is not parsed properly. As I'm still uncertain whether to go the re2c way (there the problem does not exist), I'd like to have this fixed in the standard version. However as the code is pretty subtle it would be nice if someone could have a look. Cheers, Johannes

RFC: Dillo presentation
by onepoint＠starurchin.org March 6, 2009

March 6, 2009

I have agreed to give presentation on Dillo to my local Linux Users Group this Thursday. Naturally I'm leaving it until the last minute to write anything! :-) I am attaching my crib list of essential points to cover. My aim is to give a very short talk covering * project goals * history (Dillo-1, Dillo-2.0, Dillo-2.1, soon) * development model * supported features * architecture (DPI, Dw) * future I'd very much appreciate any comments people have, particularly if you think there's anything important I have missed out. This is your chance to tell me what to tell them. (Just bear in mind that I aim to be brief, so I can't go into large amounts of detail.) Regards, Jeremy Henty

allow_white_bg and contrast_visited_color
by Johannes.Hofmann＠gmx.de March 5, 2009

March 5, 2009

Hi, as we seem to have agreed on using CSS for style customization intead of dillorc settings, I'm trying to get rid of these: link_color: visited_color: text_color: bg_color: force_my_colors: The same thing can more or less be expressed with a custom user stylesheet, so I want to remove them. The problem is non-HTML pages (plain). I would propose to simulate <body><pre> in this case and use the corresponding style. allow_white_bg: This can't be expressed with CSS. We could detect a white background in StyleEngine (like we detect font sizes smaller than font_min_size), but what color should we use instead in this case (note that it must be different enough from the text color)? contrast_visited_color: This one is hard. Consider we want to render a visited link. >From StyleEngine we get a background and a text color, but we don't know what the text color would have been if the link would not be visited. So we can't enforce a color that is different from that. Generally (and even more with CSS), background- and text-colors can change arbitrarily within a page. So there is not a background and a text color per page. standard_widget_colors: Not sure about this one. On the one hand I think that CSS support broke this. On the other hand CSS allows the page author to directly set colors of form widgets. corvid, can you please have a look? Cheers, Johannes

clipping image inputs
by corvid＠lavabit.com March 5, 2009

March 5, 2009

With <input type="image" name="name1" src="whatever" WIDTH="80" HEIGHT="14" alt="name1name1name1name1"> <input type="image" name="name2" src="whatever" width="9" height="14" alt="name2name2name2name2"> the long alt text doesn't clip. It looks like the embed knows that it's 80 pixels wide (at least the child widget area stuff in Textblock::drawLine seemed to have the right idea), but the image thinks it's 188 (in my case). PS I have "white-space: nowrap" pretty much working, but I don't know what I'm doing in Textblock very well, so it's definitely not going into this release.

Hi, I just commited http://hg.dillo.org/dillo?cs=11c6f887d649 which improves CSS performance by avoiding unnecessary style computations. Please give it a thorough testing. Cheers, Johannes
