[xwiki-devs] Anyone familiar with ANTLR?
by Vincent Massol 17 Feb '08

17 Feb '08

Hi, I'm trying to write a XWiki parser and I'm having some issue writing an ANTLR grammar for it. More specifically the following grammar doesn't recognize "{macro/}": http://dev.xwiki.org/xwiki/bin/view/Drafts/AntlrGrammarXWiki If some of you have some experience with Antlr, I'd be grateful for some help. In the meantime I'll keep searching... Thanks -Vincent

[xwiki-devs] [Architecture] New xwiki rendering component - HTML events needed?
by Vincent Massol 17 Feb '08

17 Feb '08

Hi, Here's some design details on the new xwiki rendering component I'm writing, for which I'd like to have feedback from the dev community. Sources: http://svn.xwiki.org/svnroot/sandbox/components/xwiki-rendering/xwiki-rende… In the new design, macros are parsed and generate "MacroBlock"s events in the Listener. Here are some refinements I'm proposing: * MacroBlock has a traverse(Listener) method. * In order to make Macros independent on the Listener (this is very important IMO in order to allow for any kind of transformations) we need to make the MacroBlocks emit Listener events. * Since the wiki syntax is not enough to generate all possible rendering options (for example no wiki syntax for XHTML forms) we have 2 options: 1) add as many Listener events as there are XHTML features or 2) add an onHTMLElement(...) event in the Listener * Option 2) (onHTMLElement) looks much better IMO (simpler, can evolve with the HTML spec, faster, etc) This allows for example to have a iText renderer to generate PDFs from page content which would be way more difficult if the HTML was passed as standard text (this would need to reparse again the content of Listener's onText() calls. Same applies for any Listener/Renderer since they'll need to have some special handling for HTML. Of course since WikiModel and Doxia don't have HTML events in their Listener/Sink we'll need to perform some mapping when we want to use bridge to them. It probably means we'll need to output the HTML elements as simple text events for them. WDYT? Mikhail, I'm curious to know how you're handling this use case in wikimodel. Thanks -Vincent

[xwiki-devs] [vote] XWiki charset strategy
by Sergiu Dumitriu 16 Feb '08

16 Feb '08

Hi devs, We need to decide how to handle the charset/encoding in XWiki. We have 3 options: 1. Leave it as it is. The default is ISO-8859-1, and the admin has to make sure the JVM is started with the correct -Dfile.encoding param. If another encoding is needed, it has to be changed in 4 places (web.xml, xwiki.cfg, -Dfile.encoding, database charset+collation) 2. Force it to always be UTF-8, overriding the file.enconding setting. This ensures internationalization, as UTF-8 works with any language. And I think it is a safe move, as any modern system supports UTF-8 (given that XWiki requires java 5, we can assume it will be in a modern system). This has the advantage that the code will be simpler, as we don't have to check and switch encodings, but has the disadvantage that mysql has to be manually configured for UTF-8, as by default it comes in latin1. 3. Keep it configurable, but by only specifying it in one place (xwiki.cfg or web.xml), and enforcing that encoding in the JVM (by overriding file.encoding). The default should be UTF-8. Here's my +1 for option 2, -1 for option 1, and 0 for option 3. -- Sergiu Dumitriu http://purl.org/net/sergiu/

[xwiki-devs] How to monitor the user in xwiki
by Hans-Peter Zorn 15 Feb '08

15 Feb '08

Hi all, i am currently working on integrating a recommendation system into a xwiki installation. What I need to build a statistical model is to register every link to another wiki page a particular user clicks. e.g. zorn is on Main.WebHome and clicks on SandBox.WebHome After investigating this a little, I think one way to do this would be to extend the XWikiStats subsystem. I would prefer to write simple plugin however, if such hooks already exist, but I couldn't find any. Thanks, Hans-Peter

[xwiki-devs] [VOTE] Move the title field to the Document Information panel
by Vincent Massol 15 Feb '08

15 Feb '08

Hi, I'd like to propose moving the title field in edit mode to the side, in the information panel, just before the Parent field. We have already parent and tags there and the title would fit nicely there. The main reason for this is to clear up more space for the main content edition. It's also more consistent to put the page metadata together on the side (which has a lot of unused space). Here's my +1 Thanks -Vincent PS: It really helps in Toucan skin to have that title field on the side since a major theme of Toucan is to simplify the interface and provide more space for the content.

[xwiki-devs] towards a MathTran XWiki macro for TeX-based equations
by Paul Libbrecht 14 Feb '08

14 Feb '08

Hello, we started to approach the embedding of the MathTran service for XWiki embedding of formulae. A very very rudimentary version (based on velocity macros) is at http://i2geo.net/bin/Sandbox/Formulae Clearly, we'll make a macro instead of a velo-macro, so that syntax has some input freedom (you can't put \cdot currently!), and maybe even a plugin (so as to cache at the xwiki-server-side the resulting image. That'll work well, with baseline, for html-rendered pages. That will be somewhat ugly, however, for print (gross resolution, nothing vector). Having discussed with a MathTran developer we realized it would be easy to actually use the DVI to embed for print provided the fonts are installed on the XWiki server (they are freely available). This file is very small and is in the picture's metadata. The DVI format is basically a vector format that says where to place which characters. Is it possible to extend the print features for some islands so that it "draws on a Graphics2D" ? That would solve our approach without the requirement of any installation on the XWiki-server except for the fonts. thanks in advance paul

Re: [xwiki-devs] [xwiki-notifications] r7713 - xwiki-platform/xwiki-applications/trunk/panels/src/main/resources/Panels
by Vincent Massol 14 Feb '08

14 Feb '08

I don't like that. It means Panels can break the Panel Wizard... Also it means we'll get lots of user problems when people upgrade to 1.3M2 since they won't import the new panels... IMO this needs to be fixed in the Panel Wizard and the Panels should not be changed. -Vincent On Feb 13, 2008, at 11:25 PM, sdumitriu (SVN) wrote: > Author: sdumitriu > Date: 2008-02-13 23:25:58 +0100 (Wed, 13 Feb 2008) > New Revision: 7713 > > Modified: > xwiki-platform/xwiki-applications/trunk/panels/src/main/resources/ > Panels/Backlinks > xwiki-platform/xwiki-applications/trunk/panels/src/main/resources/ > Panels/EditTranslations > Log: > XAPANELS-42: Some panels break the panel wizard > Fixed. > > > Modified: xwiki-platform/xwiki-applications/trunk/panels/src/main/ > resources/Panels/Backlinks > =================================================================== > --- xwiki-platform/xwiki-applications/trunk/panels/src/main/ > resources/Panels/Backlinks 2008-02-13 22:18:02 UTC (rev 7712) > +++ xwiki-platform/xwiki-applications/trunk/panels/src/main/ > resources/Panels/Backlinks 2008-02-13 22:25:58 UTC (rev 7713) > @@ -136,7 +136,7 @@ > </property> > <property> > <content>#set($blinks = $doc.getBacklinks()) > -#if($blinks.size()>0) > +#if($blinks.size()>0 || $showEmptyPanels) > #panelheader('Backlinks') > #set($first = true) > #foreach($docname in $blinks) > > Modified: xwiki-platform/xwiki-applications/trunk/panels/src/main/ > resources/Panels/EditTranslations > =================================================================== > --- xwiki-platform/xwiki-applications/trunk/panels/src/main/ > resources/Panels/EditTranslations 2008-02-13 22:18:02 UTC (rev 7712) > +++ xwiki-platform/xwiki-applications/trunk/panels/src/main/ > resources/Panels/EditTranslations 2008-02-13 22:25:58 UTC (rev 7713) > @@ -99,7 +99,7 @@ > <category>Information</category> > </property> > <property> > -<content>#if($xwiki.isMultiLingual()==true) > +<content>#if($xwiki.isMultiLingual()==true || $showEmptyPanels) > #largepanelheader($msg.get("panels.translation.title")) > #if(($request.language)&&($request.language! > ="default")&&($doc.defaultLanguage!=$request.language)) > #set($forcetrans = $request.language) > > _______________________________________________ > notifications mailing list > notifications(a)xwiki.org > http://lists.xwiki.org/mailman/listinfo/notifications

[xwiki-devs] Re gistering user using a validation mail (problem)
by Sachin Mittal 13 Feb '08

13 Feb '08

Hi, There is a functionality in xwiki user registration module where we can send a validation key to the user account. For the xwiki registration tab as provided two settings: 1. from email address 2. smpt server address from which the mail is to be sent. Now most smtp server require some authentication on their machine, that would mostly be the user name/password of the from email address. There are no such settings provided under the registration tab. My question is are additional settings needed, if yes then how can one add the same. Currently i get the following error when trying to send the validation mail: com.xpn.xwiki.XWikiException: Error number 10006 in 10: Could not send mail to server 199.237.236.4 port 25 error code 530 (530 authentication required for relay (#5.7.1) ) at com.xpn.xwiki.XWiki.sendMessage(XWiki.java:2981) at com.xpn.xwiki.XWiki.sendMessage(XWiki.java:3015) at com.xpn.xwiki.XWiki.sendValidationEmail(XWiki.java:2924) at com.xpn.xwiki.XWiki.sendValidationEmail(XWiki.java:2883) at com.xpn.xwiki.XWiki.createUser(XWiki.java:2833) at com.xpn.xwiki.web.RegisterAction.action(RegisterAction.java:41) at com.xpn.xwiki.web.XWikiAction.execute(XWikiAction.java:187) at org.apache.struts.action.RequestProcessor.processActionPerform(RequestProcessor.java:431) at org.apache.struts.action.RequestProcessor.process(RequestProcessor.java:236) at org.apache.struts.action.ActionServlet.process(ActionServlet.java:1196) at org.apache.struts.action.ActionServlet.doPost(ActionServlet.java:432) >From stack trace it does seem that authentication is required.
