[xwiki-devs] How to insert an image programmatically into inline form and the image will show up when the blog post inline form shows up
by du du 18 Mar '12

18 Mar '12

Hi, all, I am playing around with the blog post application, when users click on the create post button, it brings up the inline form for users to put text in, I have another requirement, we need to write some code somewhere to retrieve an image url from a database,, so when the inline form shows up after users click create post button, the image automatically shows up in the inline form, my question is where should I put the code in? also the BlogPostClass and BlogPostTemplate have TextArea objects, which create GWT inline form, this is where I need to put image in programmatically, so I am thinking about accessing the GWT code to insert image, could you all point me to the right direction about how to approach this to put image into the inline form programmatically? Thanks very much in advance David

[xwiki-devs] [Proposal] Add support for hiding long text in Message Macros
by Vincent Massol 18 Mar '12

18 Mar '12

Hi devs, I see that in several pages we have a use the following: {{error}} $error.message {{/error}} Where error is an Exception returned by a script service. This is done in the Scheduler, in the Extension Manager and in the my new IRC Bot application. The problem is that this will only show the message but not the full stack trace which contains the real problem… So here's what I propose: 1) Create an internal helper WrappingTextBlockGenerator.generate() class (I'd locate it in the Macro Transformation module for lack of a better place, see point 4 below) and method which returns the XDOM Blocks to do this. Namely two divs with the proper "class" set. 2) Introduce a VelocityTool to help deal with Exceptions. I propose to make ExceptionUtils from commons-lang available as a Velocity Tool: http://commons.apache.org/lang/api/org/apache/commons/lang3/exception/Excep… 3) Modify the Message Macro to support the feature of displaying only the first line of text and hiding subsequent lines and when the user clicks on the text, the rest unrolls. I propose to do this by introducing a new "format" parameter that you would use like this: {{info|warning|error format="compact|normal"}}….{{/info|warning|error}}. By default format would be "normal" which means everything displayed. This feature would use WrappingTextBlockGenerator.generate for the implementation. 4) Update MacroTransformation.generateError() to use WrappingTextBlockGenerator.generate 5) Modify Scheduler, Extension Manager, IRC Bot application to use this new feature. For example for the IRC Bot application: #set ($error = $botManager.getLastError()) #if ("$!error" != "") {{error format="compact"}} $error.message $exceptiontool.getMessage($error) {{/error}} #end WWDYT? Thanks -Vincent

[xwiki-devs] Your version of 'a better' XWiki
by Ecaterina Moraru (Valica) 15 Mar '12

15 Mar '12

Hi, When the XWiki development team wants to introduce some new features or when we need some improvements on existing functionality, I sometimes make proposals on how these features/improvements should look like. You can see some of my work at http://incubator.myxwiki.org/xwiki/bin/view/Improvements/WebHome IMO XWiki is a great tool for developers because they can change anything they like and make XWiki bend to their will. Also, XWiki talks a lot the 'developer/administrator' language that new users find cryptic. Some also say that the learning curve for XWiki is steep and that beginners have lots of problems in understanding the structure, finding the documentation, navigating, etc. I'm sure every developer that used XWiki as a base for constructing their project got into these 'new user' issues and tried to fix them as best as they could. Although XWiki is an open source project where anyone can contribute, sometimes time is not on our side and makes it difficult to contribute back. I would be very curious on how some 'independent' XWiki developers solved some of the usability issues XWiki is facing: how they made it more easy to use, more good looking, more intuitive, more clear, more simple. Right now I'm thinking on how to improve the homepage, but I would love to see *screenshots* of any aspect that was improved (profile, administration, rights, history, comments, anything). Sharing these screenshots could inspire others make their project better and would step outside the 'just an idea' mode. Also there is a chance we could integrate them in the platform so that everyone can benefit. Thank you for your help, Caty

[xwiki-devs] pontoon: cute localization demo
by Paul Libbrecht 15 Mar '12

15 Mar '12

Hello XWikiers, I've just had a demo of pontoon: https://pontoon-dev.mozillalabs.com/ I wonder how applicable this can be for XWiki based platforms. It is llkely to generate a bit of trash but the "in-context" adjustment really looks cute and applicable to many cases to me. paul

[xwiki-devs] [VOTE] Add a Script Service for the Component module
by Vincent Massol 15 Mar '12

15 Mar '12

Hi, I'd like to propose adding a module named xwiki-platform-component-script in xwiki-platform. It would allow a script to get access to the Component Manager (for now, we can imagine other apis later on). The idea is to replace the ugly static and "deprecated": com.xpn….Util.getComponentManager() Of course the script Service will check for Programming Rights before giving back a CM instance. This follows the strategy of offering script services for each module. Here's my +1 Thanks -Vincent

[xwiki-devs] JSON Velocity Tool (Reloaded)
by Marius Dumitru Florea 14 Mar '12

14 Mar '12

Hi devs, Following the discussion on http://lists.xwiki.org/pipermail/devs/2012-March/049889.html I'd like to add a JSON Velocity tool that has (for now) just one method: /** * Serialize a Java object to the JSON format. * <p> * Examples: * <ul> * <li>numbers and boolean values: 23, 13.5, true, false</li> * <li>strings: "one\"two'three" (quotes included)</li> * <li>arrays and collections: [1, 2, 3]</li> * <li>maps: {"number": 23, "boolean": false, "string": "value"}</li> * <li>beans: {"enabled": true, "name": "XWiki"} for a bean that has #isEnabled() and #getName() getters</li> * </ul> * * @param object the object to be serialized to the JSON format * @return the JSON-verified string representation of the given object */ public String serialize(Object object) This method is able to do what both of the initially proposed methods were able and it doesn't expose the JSON library used (so that we can change it later if we want). I'll use json-lib for the initial implementation and we can move to Jackson or other JSON library later. WDYT? I'd like to commit this ASAP. Thanks, Marius
