This TV film I wanted to see last night was so bad that I started re-reading the list of RFEs we had in mind during our "brainstorming session" some time ago. And I also started looking at the Source View mode of Composer. I think that we can, for a low cost, do much better than that (and I have some ideas about the way we can do it) : 1. user-defined text/font styles for (a) tag names (b) attributes (c) #PCDATA (d) comments (e) Processing Instructions (f) Doctype 2. increase/decrease the font size of the view 3. better prettyfying control 4. KEEP SELECTION WHEN SWITCHING TO OR FROM SOURCE VIEW I am willing to try that in my spare time but I need some input about the way to currently switch to/from source view, how we generate and reparse the source view. Other Composer people please ?

This would be great! (BTW, I think there's already an RFE somewhere for the more specific task of color syntax highlighting like the browser source view does.) We use the normal output system (which goes through the nsHTMLContentSerializer) to generate the html source from the current dom; when going back, I think we essentially do an InsertHTML of the source we're displaying (with some extra steps to preserve things like doctype and elements inside the head which aren't shown in the source view). I think the browser source view gets the source from cache and then does something like examine the source and wrap parts of it in span tags which can be colorized by CSS. It used to just take the dom tree and apply css rules to make tag names show up, but that didn't work because the tag names were anonymous content and therefore not selectable. Perhaps we can leverage the code that the current browser source view is using to colorize in order to make tags that the editor can use in our own source view. Once we have tags that CSS can bite on, the user can customize them with userContent.css. Keeping selection is hard (though I agree it would be wonderful if we could do it). The generated html source is just a string which has no direct relationship to the original dom. I could see doing some sort of trick, like sandwiching anything that's currently selected in a special span tag before calling the serializer, then looping over the source document after it's loaded and adding to the selection anything within the (now hidden by CSS) special span tags. I suppose the only hard part is ensuring that the special tags don't show up in the source view and that they're removed after we return to normal view (and on output, of course).

Here are the related bugs already filed: Caret placement retained: #47040 Color coding like browser: #58730 Find/Replace work: #76374 Print: #82239 Setting font/size: #38981 Insert/Format menus operate: #41308 Use Plaintext editor instead of textarea: #38981

The only related bug that matters is bug 38981. We must have a separate text editor with full UI and selection before *any* enhancements can be made to HTML source. It is currently a very simple kludge: using the <textarea> and is a dead end. The primary blocker is support for multiple editors on one DOM tree, which was an sfraser task and thus is now at risk. If someone can take what work Simon has for that and finish it, I'd love to work with the resulting plain text editor's UI to improve this feature, which obviously people do like.

removing myself from the cc list

I investigated a little bit how to solve this bug and I now know how (isn't it hard to write "now know how" for a frog like me :-) ) to do it. It's not very hard but it is, let's say, micro-surgery. Will spend some extra cycles on it when I am back in july. I think that it would be such a visible improvement to the source view that it prolly deserves it.

I'm on it.

Fix attached to bug 47040 and solving also this bug.
