[xwiki-devs] [VOTE] Strategy for handling translations
by Vincent Massol 02 Jan '10

02 Jan '10

Hi devs, We need to define a strategy for better handling translations. I've had a call with Guillaume and Jean-Vincent and here's the process we'd like to propose: * One person is in charge of http://l10n.xwiki.org/. This means monitoring the work there, coordinating validation of key values and ensuring validated translations are incorporated in the source tree. Guillaume is willing to take that role for now. * The XE release manager has the responsibility of taking the validated keys on l10n.xwiki.org and committing them during the Milestone 2 dev (before the RC1). * The l10n manager should ping the release manager whenever there are translated and validated keys ready to be incorporated or if there have been important changes to be included in the release after M2 has been released. * The l10n manager should test XE and the applications after the keys have been applied to ensure quality. Basically the l10n manager is responsible for the quality of translations in general. Here's my +1 Thanks -Vincent

[xwiki-devs] [VOTE] What to do with RawBlock in plain text renderer ?
by Thomas Mortagne 24 Nov '09

24 Nov '09

Hi devs, We need to decide what to do with html macro content (or any other RawBlock content) in plain text renderer. For me the rule of plain text renderer should be to print anything we are able to print which mean printing any pure text content and skip styles for which obviously we don't have syntax. RawBlock content is pure text so we should print it. Note that first version of plain text renderer was printing html content and it was lost when introducing RawBlock. Here is my +1 for printing RawBlock content in plain text renderer. WDYT ? -- Thomas Mortagne

[xwiki-devs] [Proposal] XWiki "2.0" Syntax
by Vincent Massol 27 Oct '09

27 Oct '09

Hi, Since I'm rewriting the new Rendering component (see http://dev.xwiki.org/xwiki/bin/view/Design/NewRenderingArchitecture) , we need to finalize the new syntax we want to have. Right now I'v planned to use the same wiki syntax as now (http://platform.xwiki.org/xwiki/bin/view/Main/ XWikiSyntax#HTextStyles) with only one change: all macros now need to be closed. For example: {macro}...{/macro} and {macro:text|param=value|.../} Is that ok with everyone or do we want to make changes? Thanks -Vincent

Hi Sergiu, Are you sure about this below? What's your use case? I find it strange to order by class name for an execution order.

[xwiki-devs] attachment's mime-types
by Paul Libbrecht 04 Oct '09

04 Oct '09

Hello XWiki developers, can someone explain me what is the strategy to define the mime-type of an attachment? I see not configurable map nor any setter on the attachment types. Is there any way I can enrich this or is it simply taking over the mime-type provided the browser (which, too often, ends up being application/octet-stream) ? thanks in advance paul

[xwiki-devs] adding a new jsr-223 scripting language to xwiki (clojure)

Clojure <http://groups.google.com/group/clojure> has aJSR-223 implementation according to: http://github.com/pmf/clojure-jsr223/tree/master http://groovy.codehaus.org/JSR-223+access+to+other+JVM+languages http://sayspy.blogspot.com/2009/03/interacting-between-jvm-lang-here-and.ht… Are there any examples, documentation, or suggestions of writing a "script macro" to call a new jar in WEB-INF/lib ? Any other special magic I should know? Does anything from the above suggest that Clojure couldn't be used as an Xwiki scripting language, replacing cases where Groovy scripting might normally be employed? Niels http://nielsmayer.com PS: Here's examples of easy "scripted java" programming you can do in Clojure (note the helpful parallelism constructs): http://travis-whitton.blogspot.com/2009/07/network-sweeping-with-clojure.ht… http://travis-whitton.blogspot.com/2009/06/clojures-agents-scientists-monke… It could be very useful to employ massive parallelism via such Clojure scripts, which could achieve a xwiki-based web portal performance akin to Yahoo's, Google's, etc. For example, the following describes how Yahoo works -- and would be quite easy to implement this kind of processing "for free" in Clojure with very little code: http://research.yahoo.com/files/pnuts.pdf The component responsible for multi-record requests is called the > scatter-gather engine, and is a component of the router. > The scatter-gather engine receives a multi-record request, > splits it into multiple individual requests for single records > or single tablet scans, and initiates those requests in parallel. > As the requests return success or failure, the scatter-gather > engine assembles the results and then passes them to the > client. In our implementation, the engine can begin streaming > some results back to the client as soon as they appear. > We chose a server-side approach instead of having the client > initiate multiple parallel requests for several reasons. First, > at the TCP/IP layer, it is preferable to have one connection > per client to the PNUTS service; since there are many clients > (and many concurrent processes per client machine) opening > one connection to PNUTS for each record being requested > in parallel overloads the network stack.

(I have a confusion about > macros + js working together) I have Macros/JS working together all the time, using JSX. I'm certain it's possible, given the kinds of integration I've been able to do in Exhibit&Xwiki, e.g. http://nielsmayer.com/xwiki/bin/view/Exhibit/NPRpods3 ... Here's a simple example, which are tests for my Xwiki integration of http://www.longtailvideo.com/players/jw-flv-player/ which is the media player used in the NPRpods3 application above: http://nielsmayer.com/xwiki/bin/view/Macros/JWPlayer?viewer=code http://nielsmayer.com/xwiki/bin/view/Macros/JWPlayerJSPL_Test (xwiki integration of http://home5.inet.tele.dk/nyboe/flash/mediaplayer4/JW_API_xmpl_5-2-4-0.html with an improvement, the JWplayer example doesn't work on Linux/Firefox, mine does!) http://nielsmayer.com/xwiki/bin/view/Macros/JWPlayerJSPL_Test?viewer=code (wiki-code for above) http://nielsmayer.com/xwiki/bin/jsx/Macros/JWPlayerJSPL_Test (the javascript playlist from XWiki.JavaScriptExtension[0]) ## ## Load and initialize LoadJS: defines injectJS(url) required by JWPlayer ## #includeMacros("Macros.LoadJS")## #loadjs_xwiki_init()## ## ## Load and initialize JWPlayer after LoadJS. ## #includeMacros("Macros.JWPlayer")## #jwplayer_xwiki_init()## ## ## Load JavaScript playlist from object XWiki.JavaScriptExtension[0] into ## js variable jwplayer_jspl, used below in parameter to jwplayer_embed_generic() ## function(jwpl){jwpl.sendEvent(’LOAD’, jwplayer_jspl);}. This function called ## by jwplayer’s playerReady() calback when player has been instantiated, and ## causes the javascript-based playlist to get loaded. ## $xwiki.jsx.use("$doc.fullName")## ... #set( $jw_name = "$doc.name" )## #set( $jw_player = "jwplayer_embed_generic(’$jw_name’, ’mpl’, ’&autostart=false&playlist=right&playlistsize=250&shuffle=false&repeat=always’, function(jwpl){jwpl.sendEvent(’LOAD’, jwplayer_jspl);}, ’100%’, ’385px’);" )## #jwplayer_create("$jw_name", "$jw_player")## http://nielsmayer.com/xwiki/bin/view/Macros/JWPlayerPL_Test is another test using playlists. This also calls JS jwplayer_embed_generic(), but with an external file, passed as URL/string, instead of creating the playlist in lambda-function as above. ( http://nielsmayer.com/xwiki/bin/view/Macros/JWPlayerPL_Test?viewer=code ): #set( $jw_player = "jwplayer_embed_generic(’$jw_name’, ’mpl’, ’&autostart=false&playlist=right&playlistsize=250&shuffle=false&repeat=always’, ’/xwiki/bin/view/Macros/JWPlayer_PlayList?xpage=plain’, ’100%’, ’385px’);" )## JS functions jwplayer_embed(), jwplayer_embed_generic() and macros #jwplayer_xwiki_init(), #jwplayer_create() are from http://nielsmayer.com/xwiki/bin/view/Macros/JWPlayer?viewer=code --- Going in "the other direction", here's an example of using velocity to compute results returned by Javascript: http://svn.xwiki.org/svnroot/xwiki/curriki/branches/curriki-1.8/web/src/mai… #set( $total_attachments_size = 0 ) ## javascript:getAttachmentsSize() #set( $total_attachments_names = [] ) ## javascript:getAttachmentsNames() #foreach ($attach in $doc.attachmentList) ## { #set( $ok = $total_attachments_names.add("'${attach.filename}'") ) ## append attachment filename to ArrayList #set( $total_attachments_size = ${total_attachments_size} + ${attach.getFilesize()} ) ## compute total size of atttachments #end ## } -- foreach ... function getAttachmentsNames() { return (${total_attachments_names}); } function getAttachmentsSize() { return (${total_attachments_size}); } ... lpattachments is called from an iframe. The parent document accesses the iframe'd document's javascript functions like this: ( http://svn.xwiki.org/svnroot/xwiki/curriki/branches/curriki-1.8/wiki/src/ma… ) // // get size of files in attachments iframe // function getAttachmentsSize() { return (window.frames['attachment_iframe'].getAttachmentsSize()); } // // retrieve ArrayList of filenames contained in attachment // function getAttachmentsNames() { return (window.frames['attachment_iframe'].getAttachmentsNames()); } -- Niels http://nielsmayer.com

[xwiki-devs] on new rendering
by [Ricardo Rodriguez] Your EPEC Network ICT Team 06 Aug '09

06 Aug '09

Hi all, Since almost two years ago you has done a lot of work to develop the new rendering system based on components. I can found two documents I'd been following to understand how this work has been done and what was its development state. Those are: http://dev.xwiki.org/xwiki/bin/view/Design/NewRenderingArchitecture and http://platform.xwiki.org/xwiki/bin/view/AdminGuide/Configuration#HCustomiz… I am trying now to catch up with this thread due mainly to two reasons: * At least a couple of new XWiki installations will be made public in the following weeks. It seems logical to use the last available version and take profit of all the new features. We do need to serve XWiki pages rendered as plain text. This was simple done working with XWiki 1.0 syntax. It seems to work the same way while working with XE 2.0m1 when using XWiki 1.0 syntax, but xpage=plain it is not enough when working with XWiki 2.0 syntax. I've read a number of thread related with issue in the devs list and, if I've well understood, there will be new parameters introduced in 2.0m2 to * We do need to control at least rtf and pdf outputs. So, please, are these two links still valid to follow the development of the new rendering architecture and how it affects/will affect the production of rtf and/or pdf files? What other locations I must follow, if any, to follow this development? I hope I've been able to explain what I am trying to do! All the best! Ricardo -- Ricardo Rodríguez Your EPEC Network ICT Team
