[xwiki-devs] page delete hook.
by Karel Gardas 09 Aug '11

09 Aug '11

Hello, I'm curious if there is any kind of hook or script or code executed when the page from the XWiki is deleted and which might be easily enhanced. I'm asking since during the page creation I also modify external database (page template do this) and if page is deleted the data in external db shall be also deleted to be consistent. Thanks! Karel

[xwiki-devs] |PROPOSAL] Move all retro-compatibility aspects into xwiki-legacy
by Thomas Mortagne 09 Aug '11

09 Aug '11

Hi devs, Here is the general idea: I would like to start doing important cleanup to oldcore project by moving aspect to xwiki-legacy and deprecated stuff hard to move right now. Here are the pros: * we will be able to move a lots of deprecated classes like the old event system and some others to xwiki-legacy. It's very hard now because of methods using theses APIs in XWiki class * oldcore will be quicker to build (no aspectj build anymore) * that way we make sure we don't use any deprecated APIs in platform Along with it I would also like to start separating xwiki-legacy in sub modules. In details it means that there will be two xwiki-oldcore jars, the "normal" one and the one including aspects and legacy classes. Projects will depends on the first one and the second one will actually be packaged with XE/XEM. And It will basically be the same for any other project with aspect based retro-compatibility. You can have a look at the current state which is pretty much ready to merge (need to update some code that is still using deprecated API) in https://github.com/xwiki/xwiki-platform/tree/feature-legacyprojects. Right now only oldcore have a conflicting jar package, other legacy modules are like xwiki-legacy used to be: they just contains some deprecated classes and bridges but they are not repackaging the non legacy jar because it's not really needed (no aspects). There is lots of more things to move but I would like to validate the idea and we will move stuff later. WDYT ? here is my +1 -- Thomas Mortagne

Hi Karel, Don`t forget about textareas :) It would be nice if you could, when you finish the project, cotribute it as a feature of XEclipse. The REST templates service could become a part of XE as well.

[xwiki-devs] Package name best practice
by Vincent Massol 09 Aug '11

09 Aug '11

Hi devs, I've updated the doc on http://dev.xwiki.org/xwiki/bin/view/Community/JavaCodeStyle#HPackagenames From: * All code that is **not** moved to the new XWiki Architecture based on components should use ##com.xpn.xwiki##. New architecture code should use ##org.xwiki##. To: * All code that is not located in the oldcore module should use ##org.xwiki##. Hope it's ok with you. Thanks -Vincent

[xwiki-devs] How to get the page references in javascript
by 许凌志(Jamesxu) 08 Aug '11

Hi, how can I get the current edit page's details information in javascript like, its space and its page name. Here I found that I can parse the url of the current edit pages, like /xwiki/bin/edit/Main/Newpage?editor=wiki Is there any other better ways for me to get them? -- Best wishes, 许凌志(Jame Xu) MOE KLINNS Lab and SKLMS Lab, Xi'an Jiaotong University Department of Computer Science and Technology, Xi’an Jiaotong University

[xwiki-devs] The plan of GSoC project "Auto-completion in content editors" (7.25 - 7.31)
by 许凌志(Jamesxu) 08 Aug '11

08 Aug '11

Hi, Last week I have done following things: 1. Refine the suggest lucene service, and a query "media", which have two options: "xml" and "json", each gives the xml and json results. 2. Thanks Eduard, Marius and Sergiu, with their help, I finnally find the right search queries of suggest lucene service to get right suggestion results. 3. The autosuggestion can use the real datas from xwiki now. In this week, I am going to do the following things: 1. Implement the whole context for link suggestion, include "attach:", "@", "." and "||".( I have done some designations, but still want to discuss with mentors) 2. Consider to implement the ctrl+space to re-open the suggestion box according to the different contexts of link suggestion.(after the 1 is finished) -- Best wishes, 许凌志(Jame Xu) MOE KLINNS Lab and SKLMS Lab, Xi'an Jiaotong University Department of Computer Science and Technology, Xi’an Jiaotong University

[xwiki-devs] The plan of GSoC project "Auto-completion in content editors" (8.8 - 8.14)
by 许凌志(Jamesxu) 08 Aug '11

08 Aug '11

Hi, Last week I have done following things: 1. Refine the codes according to the code review of Marius. 2. Add the shortcut for identifying the context of link, and re-generate the suggestions, as Marius's suggestion, the shortcut should be ctrl+space, but I found it the ctrl+space is not working in most of my OS systems, if I change to other shortcuts, like ctrl+any key except 'space', everything will be fine, I search the problem in google, I found the same thing happens in eclipse, I tested it, the ctrl+space is not working in eclipse either. I think the reason might be the shortcut is used for changing text input, like change the the english input method to chinese input method. Unfortunately, there is no good solutions found in google. So, I change the shortcut to ctrl+enter(return). I think another solution is that I make the shortcut configurable. In this week, I will do the following things； 1.Add the default suggestions for sub-trigger "attach:", "." and "@". 2.Refine the suggestion box according to Marius' suggestions in the reply for the mail "The plan of GSoC project "Auto-completion in content editors" (8.1 - 8.7)". 3.Add the relative references for link generation. -- Best wishes, 许凌志(Jame Xu) MOE KLINNS Lab and SKLMS Lab, Xi'an Jiaotong University Department of Computer Science and Technology, Xi’an Jiaotong University

[xwiki-devs] The plan of GSoC project "Auto-completion in content editors" (8.1 - 8.7)
by 许凌志(Jamesxu) 08 Aug '11

Hi, Last week I have done following things: 1. Implemented the sub-triggers 'attach:', '@', '.' for link autosuggestion. I record a video(see:http://youtu.be/7lXeORkI6Ns) of how to use this triggers under link suggestion context. But still have some problems: a. I didn't implement the trigger for attribute "||", because the suggestion trigger type and behaviour are a bit different from the others, for example, when you type "||" the attributes of the link will be shown, and when user select one, then type '="' the value should be suggested to user, and if user want to add second attributes to the link, he can type "space" key and then the suggestion for available attributes should also be shown. The process are a bit complex, and the cost of implementation is high compare to the utility of the functions. So I decide to abandon this sub-triggers and focus on the trigger "attach:", "@" and "." only which are more useful when user add or edit links. b. Not full tested, I test most cases I can think of, and ask my classmates to use this function and gave me some feedback, I did found some bugs, and fixed them, but I am not very sure some unexcepted bugs will come up c. I didn't implement the default suggestions for "attach:", "." and "@" sub-triggers, I need to discuss with mentor this week. 2. Thanks Marius and Sergiu, with their help, I find all the server side search service for getting the suggestions of the link sub-triggers. 3. Thanks Marius, with his help, I can refine the default Panels.Recent Modified page to get the recent modified pages and attachmens as the default suggestions for link trigger "[[". In this week, I am going to do the following things: 1. Implement the default suggestions for sub-triggers "attach:", "." and "@". 2. Implement the ctrl+space to re-open the suggestion box according to the different contexts of link suggestion. -- Best wishes, 许凌志(Jame Xu) MOE KLINNS Lab and SKLMS Lab, Xi'an Jiaotong University Department of Computer Science and Technology, Xi’an Jiaotong University

[xwiki-devs] [Discussion] XEM Workspaces feature integration issues
by Eduard Moraru 05 Aug '11

05 Aug '11

Hi devs, As part of the process of integrating the Workspaces feature into XEM, I have identified certain problematic integration points. == Context== For those that don't know about the Workspaces feature, here's an initial design page that can still be considered relevant with respect to the current prototype http://dev.xwiki.org/xwiki/bin/view/Design/Workspaces Technically, workspaces are subwikis that can be created by any user (not just admins), that handle only global users (don`t allow local users) and that manage 3 types of workspace/subwiki membership (1. open, 2. on request with admin validation and 3. only on invite). The main wiki contains the workspaces application and is the entry-point from where you can create/browse workspaces. Of course, since it's part of the Wiki3.0 research project ( https://wiki30.xwikisas.com ), the main focus is the user and social interactions. The current prototype ( https://github.com/xwiki-contrib/wiki30 and issue tracker http://jira.xwiki.org/jira/browse/WIKITHREEDOTO ) was built as a forked XEM distribution that comes with 2 features (workspaces and real-time editor). == Issues == For the integration of the Workspaces feature (as a XEM extension), the following problems restrict the Workspace feature from overriding certain XWiki elements while extending them: I) Main Wiki level (for the Workspace Manager Application) 1) Extend XWiki.GroupSheet and templates/getgroupmembers.vm - Add 'follow' action to the group's livetable - Add 'comment'(About) and 'tags' columns to the group's livetable 2) Extend XWiki.XWikiUserSheet - Add 'Workspaces' tab with list of joined workspaces and possibility to list their activity. 3) Extend XWiki.SearchSuggestConfig - Show Workspaces in search suggestions without affecting existing ones. 4) Extend menuview.vm - Show 'Workspace' entry in the 'Add' menu - Show 'Workspace Directory' entry in the 'Wiki' menu - Show 'Main Wiki' entry in the 'Wiki' menu II) Workspace level (for the workspace template) 1) Extend Main.Dashboard - Add new widgets(Workspace Information, Top active users, List of available Apps) without affecting the existing ones. -- There should be a clear difference between Gadgets (contain just the code and are reusable), Dashboard descriptor (for taking care of which gadgets to include and how to do the layout) and the Dashboard macro. To add some gadgets in a dashboard from an application, you should only have to override the dashboard descriptor but not also the existing gadgets. 2) Extend XWiki.AdminSheet - Add 'Workspace' sections in the 'Configuration' category - Replace the section 'Users' from 'Users & Groups' category with a 'Workspace Users' section 3) Customize templates/rightsUI.vm - Hide scope selector for Users in rights UI and use global users as default There is always the option of doing all of the above trough JSX, but that is a far from perfect solution. The general topic of these issues is that applications should be allowed to better extend XWiki and should not be confined to only the "content" section of a wiki page. In particular, almost all of these issues require their own thread and can be considered part of bigger problems, but I think it's a good start to list them here and see what discussions come out of them. The goal is to be able to install Workspace Manager on top of XEM without partially overriding certain pages or touching templates so that the upgrade of the underlying XEM is not affected. Any feedback on these issues is greatly appreciated. Thanks, Eduard

[xwiki-devs] [Discussion] Some things that could be integrate in XE/XEM as a result of Wiki3.0
by Eduard Moraru 05 Aug '11

05 Aug '11

Hi devs, Based on my previous mail [1], I`ve isolated a small list of stand-alone elements that could be integrated into XE/XEM as a result of the work done on the Wiki3.0 research project: = XE = 1. Add 'Follow' button in GroupSheet's livetable - already done [3][4], needs a final review 1.1 Add 'About' and 'tags' columns in the GroupSheet's livetable. 2. Group Manager/Inviter (invite users to a group) - needs refactoring in order to extract it as an individual feature. = XEM= 3. Wiki descriptor editing from subwiki administration section - needs a bit of refactoring to make wiki descriptor editing and then reuse it for workspace descriptor editing. 4. Main wiki link in the top menu, under the 'Wiki' section to be able to go to the main wiki. I`d like to have your opinion on whether they are desired features to be integrated into XE/XEM. Note: Don`t forget to check out the demo instance [5] I`ve set up at http://wiki30-demo.xwiki.com to get a better view over the work done and, maybe suggest other things that could be reused.
