Hi guys,
Some time back we started improving title handling, I'd like that we continue this and I'm proposing some further improvements below:
* Make the title field contain wiki syntax (same as the content field) instead of just velocity
I am not a big fan of seeing code (of any kind) in titles. IMO, it is bad practice and we should discourage people from doing it. You have lots of problems when some application lists the titles of pages with code in their title or, worse, when the application tries to render those titles. You have all sorts of security issues and generally bad things when the writer of that title does not assume that it is going to be rendered outside his page. I know it is a cool feature, but it is causing too much headache to handle correctly.
AFAIK, 90% of the times when we need the title to be rendered is because we need translation keys. We could very well have a filtered wiki syntax, that allows only calls to the new {{translation}} macro.
As Thomas said, there are cases when something else is used (with velocity code, yes). Now this something else might indeed be only 10% of the cases, but we should still keep it possible. Not show it in the UI because 90% of the people don't care about it, but still keep it possible.
An alternative to people that *really* want to generate their title trough a script is to actually keep the title extraction from the document content and make them have to generate a <h1> element from the content, not from the title. This means that they have to leave the actual title empty for the extraction to be triggered and, if I am not mistaken, applications that want to list document titles can use api.Document.gerRenderedTitle(document.syntax.toIdString()) (as they probably did before) and the first heading (that is either static or programmatically generated)
No, not programatically generated. Last time I checked, title extraction tool was not evaluating scripts. Also this extraction thing is really crap because it's hard to use: it uses a hack to not display the title twice, which is to search for the h1 with a regex (aaaaaa!) in a vm to put a hidden class so that it's not displayed. This makes it terribly painful to re-use those title and content somewhere else since you don't know if you'll have 2 titles or just one (in a pdf export, for example). Thanks, Anca
will be displayed, which sounds good to me.
So I would be +1, considering the comment above (restricted use of macros).
* Make the title field a textarea so that we can have more than 1 line * Display a textarea of 1 line initially (to preserve space) but enlarge the textarea visibility by several line on the first Enter keypress in the field * Stop trying to extract title content from the doc content
+1
* Have a backward compat param to still support the old mode, but have it off by default in 4.2/4.3 <side> * Introduce a {{i18n}} macro (or {{translate}}, or …)
+1
</side>
Advantages: * Same as the content field - More consistency * More power since we use wiki syntax and we can use any script language
More problems for devs, more raised eyebrows from users. :)
* Removes the WTF symptom when a user edits a page having velocity script in the title since they'll see it displayed in WYSIWYG mode with the title content evaluated * Removes the uncertainty about title extraction (for ex if some macro generates headings) but still allow it if it's really needed - Since the user will be able to write scripts in the title textarea and those scripts can extract stuff from the doc content if they really need it * We'll be able to add a l18n macro and thus display the title translations nicely in the wysiwyg editor
WDYT?
Thanks -Vincent
