css todo

by Johannes.Hofmann＠gmx.de

Hi, here's the current todo list: * convert more of html.cc and form.cc to the new style handling. see Html_tag_open_a() as an example. Basically every style change that happens due to an HTML attribute (e.g. bgcolor="black") should be handled by passing a corresponding hint in CSS form to the styleEnginge using the setNonCssHints() methods. This way these attributes can be overridden e.g. by the user stylesheet as defined in the CSS standard. Other styling that is fixed for the HTML element in question (e.g. font size changes caused by <small>) should be replaced by corresponding entries in the user-agent stylesheet (see CssContext::buildUserAgentStyle()). There is an example user-agent stylesheet at http://www.w3.org/TR/CSS21/sample.html One of the more complex parts to convert is list handling (Html_tag_open_li()). * Reenable shaded colors as default for table borders. However CSS21 states (http://www.w3.org/TR/CSS21/box.html#border-color-properties) "If an element's border color is not specified with a border property, user agents must use the value of the element's 'color' property as the computed value for the border color." Not sure what to do here. What do you think? * Switch "width" and "height" handling from dw::core::style::Length to CssLength. Problem is how to handle relative lengths as they occur in Html_parse_length_or_multi_length(). They don't seem to exist in the CSS model. * Remove functions from html.cc that are now empty (e.g. Html_tag_open_em()). DilloHtml should be able to handle NULL for TagOpenFunct and TagCloseFunct of TagInfo. Or we could use a default function. * Enhance the CSS parser (or tokenizer) to properly ignore CSS comments. * Enhance the CSS parser to handle more complex CSS selector definitions (see http://www.w3.org/TR/CSS21/selector.html) * Figure out how to implement more complex selectors in the CssSelector class. At the same time think about how to speed up selector matching (currently on every opening tag all selectors are checked). Cheers, Johannes

I had figured the shaded colors were just for giving tables and rulers a three-dimensional appearance.

Maybe the answers/suggestions should always go on the website somewhere so that you don't have to repeat yourself to people who just disappear. [So much ink has been spilled in the free software world over the years about being very very welcoming -- usually in the context of why women have better things to do than contribute to free software -- and I can really see now why those involved in projects might not roll out the parades and fireworks until seeing attempts at patches or at least detailed discussion...]

Debian seems to ship dillo with a patch for basic authentication: http://patch-tracking.debian.net/patch/series/dl/dillo/0.8.5-4.1/01_i18n Might be worth looking at. Cheers, Johannes

shaded colors and css

by Johannes.Hofmann＠gmx.de

Hello, mapping css properties to dw::core::style::Style members went very smooth, because Style was obviously implemented with css in mind. Just for the shaded color thing I can't find a corresponding concept in css. What exactly is the definition of a shaded color? Is it just a bit darker than the normal one? Does anyone know the corresponding concept in css? Cheers, Johannes

New developers?

by jcid＠dillo.org

Hi, Some people have written me expressing their will to join as developers. They have introduced themselves, asked questions and for some advice. I've answered, hinted and made suggestions. Since all of them have remained silent, I wonder whether they are concentrated studying the code, or simply changed their mind... Are you still there? -- Cheers Jorge.-

Yes, that's simple to do. Even more, currently (i.e. with the mercurial repository) you can specify *your* CSS stylesheet in ~/.dillo/style.css, and tailor it for your needs. As remote stylesheet loading isn't hooked yet, you can see the desired effect now. > I can really remember cases where I switched from firefox to dillo > because css (or its interpretation by firefox?) was so bad that I even cannot > click on some links. > > But if course, in more cases having css is really great! > > > For instance, if just colors were working OK (i.e. rendering > > looked better with CSS-colors support), that's be a good starting > > point. > > Yes, colors would be nice.

In my opinion there are a lot of sites which are more usable on mobile devices or devices with unusual screen sizes (800x480 like the eeepc) without CSS. I can really remember cases where I switched from firefox to dillo because css (or its interpretation by firefox?) was so bad that I even cannot click on some links. But if course, in more cases having css is really great! > For instance, if just colors were working OK (i.e. rendering > looked better with CSS-colors support), that's be a good starting > point. Yes, colors would be nice. That would probably give the opportunity to write small patches for e.g. font support in CSS without the need for deep conceptual decisions. So that can be a starting point for developers which are not that deep in the code yet. Greetings Andreas Kemnade

A warning about HTTPS and proxies

by corvid＠lavabit.com

In the dillo 2.0 dillorc, I had written that HTTPS uses wget, and that configuring wget to use a proxy would therefore send https traffic through it. That's wrong; I was repeating outdated information. Right now, HTTPS will not use a proxy at all. I bring this to your attention in case it matters to those using Tor and the like. ------ In other news, have you noticed that the dillo website is particularly speedy now? Andreas turned on HTTP compression :)
