[xwiki-users] Put users/group with modified access rights/permissions at the top
by Adrian Fita 14 Jun '13

14 Jun '13

Hello. I am having some tens of pages of groups and users and checking the rights on spaces/pages is a real chore. Currently I have to manually pass through all the pages to check the access rights and to discover what groups/users have the rights modified from the default. I would find it very valuable to have the groups/users that have the access rights/permissions modified from the default to the top when viewing the access rights for a space/page. Would you consider implementing this functionality in future versions? Thanks. -- Adrian Fita

[xwiki-users] A new XWiki Model! (sort of)
by Caleb James DeLisle 14 Jun '13

14 Jun '13

Hi guys, I've been working on this little side project which I originally needed to scratch a personal itch that came up during my work on the Resilience research project. I needed an efficient way to generate XWiki export (.xar) files and post them to a running wiki for rapid prototyping. In the past I would do some work from within the wiki and once the bulk of the work was done, I'd export an xar file and unzip it. Fixing up the XML and making small changes would be done by hand editing the XML dumps. To test it, the XML files would be packaged into .xar file using Maven then uploaded into the wiki by using the import function in the Admin interface. There are a few problems with this process: 1. Manually editing XMhelL files. 2. My attention span lasts from `mvn clean install` to `[INFO] Scanning for projects...` 3. The turnaround cycle from making a change in the git repository to seeing it in the wiki is somewhere around 2 minutes (edit, compile, upload in browser, test) My solution is called xwiki-tools, it's a Javascript framework for scripting the creation of XWiki packages with documents, objects and classes. Code Golf example: This is the shortest xwiki-tools script which will run (it makes a .xar file): var XWiki = require('xwiki-tools'); var pack = new XWiki.Package(); pack.setName("XWiki - Contrib - XWiki Tools Tiny Example"); pack.setDescription("package name, description and extensionId are required"); pack.setExtensionId("org.xwiki.contrib:xwiki-tools-tiny-example"); var doc = new XWiki.model.XWikiDoc(["Main","TinyExample"]); doc.setContent("A code-golf example of making an XWiki .xar file with 1 document."); pack.addDocument(doc); pack.genXar('XWikiToolsTinyExample.xar'); You can copy/paste this little .js script into a file and run `node yourFile.js` and it will output XWikiToolsTinyExample.xar. But wait, there's more! xwiki-tools doesn't just allow you to wrap little documents into .xar files, it allows you to add attachments, XObjects and even define your own XClasses. It can also generate more than a xar file, it can post the package directly to a running wiki which allows you to edit a file, run the command, page over to the browser and immediately see your changes! If you want, it can also generate output as an Apache Maven build. Check out the example here: https://github.com/cjdelisle/xwiki-tools-example to learn how to add attachments, XObjects and XClasses to your package and how to post to a wiki or generate a Maven build. Performance: user@ubnta8:~/wrk/resiliance/xwiki-tools-example$ time ./do >/dev/null real 0m0.643s user@ubnta8:~/wrk/resiliance/xwiki-tools-example$ time ./do --mvn >/dev/null real 0m0.416s user@ubnta8:~/wrk/resiliance/xwiki-tools-example$ cd mvnout/ user@ubnta8:~/wrk/resiliance/xwiki-tools-example/mvnout$ time mvn clean install >/dev/null real 0m20.578s XWiki Classes: So you've decided you want to give this a shot and you have a big ugly class which you need to represent. If you've looked at one of the existing classes such as: https://github.com/cjdelisle/xwiki-tools/blob/master/lib/model/classes/Wiki… then you know what it needs to look like but getting your class in that form would be painful. Fortunately there is a tool which reads your .xml file with the XClass and prints a .js file like the one above. Just unzip the xar export from XWiki and run the following: node ./bin/describeclass.js /path/to/YourBigClass.xml Note: some of the class properties are unimplemented so some classes will not work. License: LGPLv2.1, same as XWiki, generated code/data explicitly exempted. Thanks, Caleb

[xwiki-users] How to add all users to the XWikiAllGroup?

Hello. I imported a XAR from a backed up xwiki instance, but the users were not added in the XWikiAllGroup. There are many users. How can I add them easily to the XWikiAllGroup? Manually add each one of them is out of the question... Thanks, -- Fita Adrian

[xwiki-users] Skin for use as CMS for "static" web site?
by joel＠mentics.com 13 Jun '13

13 Jun '13

Is there a Skin or a setting or something so I could use XWiki as a CMS for a web site? Something that if you're not logged in, it will not show any wiki related functional things at all. What I'd like to do is configure my XWiki install with 3 spaces: "static" web site for default space, then blog and wiki spaces that would use the default skin. I've looked into building a custom skin, but it seems like this is something someone might have already done so asking to avoid reinventing the wheel. Thanks!

[xwiki-users] Rescue changes on the exception when saving
by Marcin Zajączkowski 12 Jun '13

12 Jun '13

Hi, On save I've got "context: Exception while parsing HTML". Page was reloaded only with previously saved changes. A page was edited in WYSIWYG mode. Is it possible to rescue changes which have been done since the last save? Maybe XWiki keeps internally some drafts which could be used? Marcin

[xwiki-users] Diagram application - 5.0.1 xwiki
by Jaume Giribert Peraire 11 Jun '13

11 Jun '13

Hi, I tried to install the Diagram Application in a fresh install of xwiki Enterprise 5.0.1 ( http://extensions.xwiki.org/xwiki/bin/view/Extension/Diagram+Application) I'm able to see the diagram viewer/editor from the Diagram Space but unable to display anything in a wiki page and the "save" options from menu are shown greyed (I use the save option from wiki page). I have tried to display the diagram using the Display Macro without any luck (no render). In place, I can only see diagram code in wiki page i.e: <root><mxCell id="0"/><mxCell id="1" parent="0"/><mxCell id="2" value="" style="ellipse" vertex="1" parent="1"><mxGeometry x="410" y="240" width="80" height="80" as="geometry"/></mxCell><mxCell id="3" value="" style="ellipse" vertex="1" parent="1"><mxGeometry x="330" y="260" width="80" height="80" as="geometry"/></mxCell><mxCell id="4" value="Double
Rounded Rectangle" style="shape=ext;double=1;rounded=1" vertex="1" parent="1"><mxGeometry x="240" y="290" width="120" height="60" as="geometry"/></mxCell></root> Have anyone tried this application with 5.0.X versions? Thanks in advance!
