sdumitriu - (16/05/2008 00:12): Hi rrodriguez 
rrodriguez - (16/05/2008 00:12): Hi Sergiu
rrodriguez - (16/05/2008 00:12): Sorry for the raw question!
rrodriguez - (16/05/2008 00:12): But I do need to work this out :-(
sdumitriu - (16/05/2008 00:12): Sure
sdumitriu - (16/05/2008 00:13): It's a css file, but I don't know which
sdumitriu - (16/05/2008 00:13): I'm looking now
rrodriguez - (16/05/2008 00:13): thanks! I though some more machinery would be involved
sdumitriu - (16/05/2008 00:15): pdf.css
rrodriguez - (16/05/2008 00:15): looking for it…
sdumitriu - (16/05/2008 00:15): I think it doesn't exist
rrodriguez - (16/05/2008 00:15): :-(
sdumitriu - (16/05/2008 00:16): You just create an empty file
rrodriguez - (16/05/2008 00:17): Must I put it in my skin folder?
sdumitriu - (16/05/2008 00:17): Where would you like to put it?
rrodriguez - (16/05/2008 00:18): It doesn't matter
sdumitriu - (16/05/2008 00:18): Then yes
rrodriguez - (16/05/2008 00:18): I mean, this is not a problem right now
rrodriguez - (16/05/2008 00:18): Is there an example about its content?
sdumitriu - (16/05/2008 00:18): Hm, doesn't seem to work
sdumitriu - (16/05/2008 00:19): Wait a bit
rrodriguez - (16/05/2008 00:19): of course
sdumitriu - (16/05/2008 00:32): Actually it works
sdumitriu - (16/05/2008 00:32): But the library applying the CSS sux
sdumitriu - (16/05/2008 00:33): It supports just a bit of CSS
sdumitriu - (16/05/2008 00:33): It doesn't support * in selectors
rrodriguez - (16/05/2008 00:33): Is it a XWiki library?
sdumitriu - (16/05/2008 00:33): It doesn't accept !important
rrodriguez - (16/05/2008 00:34): I am afraid I don't know what parts are involved in the generation of the rtf file
sdumitriu - (16/05/2008 00:34): No, it's css4j
rrodriguez - (16/05/2008 00:35): so, XWiki is using css4j to control the appearance of PDF and RTF exported files?
sdumitriu - (16/05/2008 00:35): Yes
sdumitriu - (16/05/2008 00:36): XWiki generates an xhtml file
sdumitriu - (16/05/2008 00:36): And css4j takes a stylesheet and converts the rules in that file to inline style
sdumitriu - (16/05/2008 00:36): Si if I put in the css:
sdumitriu - (16/05/2008 00:36): a { font-size: 20px; }
sdumitriu - (16/05/2008 00:37): Then css4j will make all links have a style="font-size: 20px; " attribute
rrodriguez - (16/05/2008 00:37): is there not a default stylesheet?
rrodriguez - (16/05/2008 00:38): or from a different point of view, how the default appearance is generated?
sdumitriu - (16/05/2008 00:41): By apache-fop
rrodriguez - (16/05/2008 00:42): googling for apache-fop…
rrodriguez - (16/05/2008 00:43): I've been there before… but it looked hard
sdumitriu - (16/05/2008 00:43): Hm, my mistake, there's also xhtml2fo.xsl
sdumitriu - (16/05/2008 00:43): That one is in the xwiki-core jar
rrodriguez - (16/05/2008 00:44): so, we have a bunch of pieces
rrodriguez - (16/05/2008 00:44): css4j
rrodriguez - (16/05/2008 00:44): apache-fo
rrodriguez - (16/05/2008 00:44): xhtml2fo.xsl
rrodriguez - (16/05/2008 00:45): a document is stored in XML format in XWiki
rrodriguez - (16/05/2008 00:45): what is the next step toward a rtf?
sdumitriu - (16/05/2008 00:46): No, the document is not stored as XML
sdumitriu - (16/05/2008 00:46): The process is like this:
sdumitriu - (16/05/2008 00:46): (take notes and put them on xwiki.org :p )
rrodriguez - (16/05/2008 00:47): I've Omnigraffle up and running!
rrodriguez - (16/05/2008 00:47): :-)
sdumitriu - (16/05/2008 00:48): The document is parsed & rendered as it happens for displaying in the browser, but instead of using view.vm as the main template, pdf.vm is used
rrodriguez - (16/05/2008 00:48): And of course this document is not stored in XML format, but in "xwiki" format.
sdumitriu - (16/05/2008 00:49): pdf.vm outputs just a bit of XHTML wrapping, while view.vm outputs a lot of stuff, like links to css and js files, the menu, the panels…
sdumitriu - (16/05/2008 00:49): Yes, the wiki content
sdumitriu - (16/05/2008 00:49): After pdf.vm is parsed by velocity and rendered by Radeox, we have the plain xhtml file
rrodriguez - (16/05/2008 00:50): OK (well, this ok must be carefully considered)
sdumitriu - (16/05/2008 00:51): Well, it may not be a correct xhtml, because some people have the nasty habit of putting broken html snippets found on the net, like 


 or 
sdumitriu - (16/05/2008 00:51): So, jtidy is used to clean-up the source xhtml to an intermediary xhtml
sdumitriu - (16/05/2008 00:52): After that, css4j is used to apply some css to this xhtml
rrodriguez - (16/05/2008 00:53): pdf.css in all cases?
sdumitriu - (16/05/2008 00:53): The css is taken from the pdf.css file, and from a PDF template
sdumitriu - (16/05/2008 00:54): The pdf template is a bit longer to explain, here goes:
rrodriguez - (16/05/2008 00:54): just a doubt here :-)
sdumitriu - (16/05/2008 00:54): When exporting the PDF, you can add to the URL &pdftemplate=Some.PDFTemplate
rrodriguez - (16/05/2008 00:54): the path to PDF and to RTF are the same until this point?
sdumitriu - (16/05/2008 00:55): That is the name of the document that holds the template
sdumitriu - (16/05/2008 00:55): The template is an XWiki object, from the class XWiki.PDFClass (it doesn't exist by default, but you can create it)
sdumitriu - (16/05/2008 00:55): From that xobject, the "style" property can contain additional css content
sdumitriu - (16/05/2008 00:56): So you can have different templates for generating the pdf :)
sdumitriu - (16/05/2008 00:56): Yes, the PDF and RTF are always done the same way
sdumitriu - (16/05/2008 00:57): So, after css4j does its job, we have yet another intermediary xhtml
rrodriguez - (16/05/2008 00:58): what characteristics are controlled by the template and what by the css?
sdumitriu - (16/05/2008 00:58): After that, xhtml2fo.xsl is applyed on the xhtml to obtain an xsl-fo document
sdumitriu - (16/05/2008 00:59): http://www.w3.org/TR/xsl/
sdumitriu - (16/05/2008 00:59): xhtml2fo.xsl contains some styling rules, too
sdumitriu - (16/05/2008 01:00): apache fop is then used to convert the xsl-fo content into the final document
rrodriguez - (16/05/2008 01:01): so, we do have three styling rules locations so far… the template, the css and xhtml2fo.xsl
sdumitriu - (16/05/2008 01:02): The good thing about fop/xsl-fo is that the xsl-fo document is independent of the final result
sdumitriu - (16/05/2008 01:02): So we can export the wiki documents into many formats
rrodriguez - (16/05/2008 01:03): As xhtml2fo.xsl is at the end of the process, does make it sense to consider it as the suitable place to control the final appearance of a document?
sdumitriu - (16/05/2008 01:03): Here are the formats supported by fop: http://xmlgraphics.apache.org/fop/0.95/output.html
sdumitriu - (16/05/2008 01:04): Well, it is certainly suited, but not recommended
sdumitriu - (16/05/2008 01:04): Because it is packaged in the core jar
sdumitriu - (16/05/2008 01:04): So you have to be careful when upgrading
rrodriguez - (16/05/2008 01:04): I see
sdumitriu - (16/05/2008 01:04): You can put it in WEB-INF/classes/
rrodriguez - (16/05/2008 01:05): yes, but it is new problem for upgrades…
rrodriguez - (16/05/2008 01:06): pdf.css in the skin folder?
rrodriguez - (16/05/2008 01:06): Is it finally an option?
rrodriguez - (16/05/2008 01:07): RTF output is currently unmaintained and lacks many features compared to other output formats. Using other editable formats like Open Document Format, instead of producing XSL-FO then RTF through FOP, might give better results.
rrodriguez - (16/05/2008 01:07): from http://xmlgraphics.apache.org/fop/0.95/output.html#rtf :-(
sdumitriu - (16/05/2008 01:07): That is the most simple option
sdumitriu - (16/05/2008 01:07): But the problem is that css4j is so lame
sdumitriu - (16/05/2008 01:07): You will have to play around to see it's bugs
rrodriguez - (16/05/2008 01:08): It will be probably enough for what I need that, but in the near future a more powerful way to generate "Word ready" documents will be needed here :(
rrodriguez - (16/05/2008 01:09): I think there is a GSoC for importing Word files into XWiki, but i don't remember nothing related with exporting to a "Word compatible" format.
sdumitriu - (16/05/2008 01:09): If we find a good word generating library, then we'll do that
sdumitriu - (16/05/2008 01:10): You can start by making a Jira issue
rrodriguez - (16/05/2008 01:10): Indeed!
rrodriguez - (16/05/2008 01:10): But I was not sure what I was talking about :-(
rrodriguez - (16/05/2008 01:10): And I am not sure yet! 
rrodriguez - (16/05/2008 01:11): But I have at least a collection or ordered items! Some thing like a process.
rrodriguez - (16/05/2008 01:13): do you know if it is possible to control pictures position and resolution in a generated RTF by using css4j?
sdumitriu - (16/05/2008 01:14): What do you mean by resolution?
rrodriguez - (16/05/2008 01:15): pixels/lenght unit
rrodriguez - (16/05/2008 01:15): but controlling size would be enough now!
sdumitriu - (16/05/2008 01:15): Don't know
sdumitriu - (16/05/2008 01:15): Size, yes
sdumitriu - (16/05/2008 01:15): That can be controlled
rrodriguez - (16/05/2008 01:15): It is enough
sdumitriu - (16/05/2008 01:15): Add:
rrodriguez - (16/05/2008 01:15): now
sdumitriu - (16/05/2008 01:16): img { width: 10cm; }
rrodriguez - (16/05/2008 01:16): I'll try right now
rrodriguez - (16/05/2008 01:21): It worked!
rrodriguez - (16/05/2008 01:22): but… there is always a but :-) this control width but the height is not modify. I don't know if it is possible to force to keep aspect ratio working with CSS. 
rrodriguez - (16/05/2008 01:23): If it is not possible, this option becomes unusable. It could only help when all the pictures in a document have the same initial size.
sdumitriu - (16/05/2008 01:24): What? The aspect ration isn't preserved??
rrodriguez - (16/05/2008 01:25): it is not.
rrodriguez - (16/05/2008 01:27): http://tinyurl.com/5zc74q
rrodriguez - (16/05/2008 01:50): Sergiu: I do need to go to bed…  :( 
rrodriguez - (16/05/2008 01:50): This aspect ratio issue is preventing to get a reasonable output from here.
sdumitriu - (16/05/2008 01:51): I don't know why is that happening
sdumitriu - (16/05/2008 01:51): It shouldn't
rrodriguez - (16/05/2008 01:53): I will google and searchmash for it and play a bit around looking for an explanation. I will move this issue to Jira and keep the thread updated. Thanks for your help!!!
sdumitriu - (16/05/2008 01:54): You're welcome
sdumitriu - (16/05/2008 01:54): Good night

evely_24 - (16/05/2008 13:23): Hi guys, I need a little help with the Application Manager. For a newly created application, there are several fields in the app object:  dependencies, applications, documents, documents to include, documents to link. I don't get the difference between the last 3. Anyone could explain please?
evely_24 - (16/05/2008 13:24): If i want to include some documents from the XWiki space in my application, where should i put the list of documents? In which of those 3?
evely_24 - (16/05/2008 13:27): I don't get this :    * documents to include in place of copy : Used in case of wiki template mainly. Documents listed here will ne copied in the new wiki but with overloaded contents that include the template wiki one
evely_24 - (16/05/2008 13:27): ex :
evely_24 - (16/05/2008 13:27): #includeInContext("templatewiki:Space.Document")
evely_24 - (16/05/2008 13:27): anyone can explain a little bit?
evely_24 - (16/05/2008 13:29): please? :)
sdumitriu - (16/05/2008 16:10): vmassol: I'm waiting for comments on http://lists.xwiki.org/pipermail/devs/2008-May/006692.html
vmassol - (16/05/2008 16:10): sdumitriu: yep
vmassol - (16/05/2008 16:10): I have big pile of emails to catch up with…
vmassol - (16/05/2008 16:11): been away for 2 weeks now from xwiki dev
vmassol - (16/05/2008 16:11): (dunno if you're subscribed to my tweets)
sdumitriu - (16/05/2008 16:11): I don't tweet
vmassol - (16/05/2008 16:12): no but you could follow us
vmassol - (16/05/2008 16:12): it's very informative
vmassol - (16/05/2008 16:12): we're almost all tweeting at xwiki
vmassol - (16/05/2008 16:12): maybe there's a tweet to RSS feed available somewhere
sdumitriu - (16/05/2008 16:20): And also on http://lists.xwiki.org/pipermail/devs/2008-May/006710.html
sdumitriu - (16/05/2008 16:20): And http://jira.xwiki.org/jira/browse/XWIKI-2377
vmassol - (16/05/2008 16:21): and probably some more… :)
sdumitriu - (16/05/2008 16:21): Well, those are the most important for me
vmassol - (16/05/2008 16:21): re http://jira.xwiki.org/jira/browse/XWIKI-2377
vmassol - (16/05/2008 16:21): we already discussed it I think
sdumitriu - (16/05/2008 16:22): Yes, but read the comments
vmassol - (16/05/2008 16:22): my recall is that I was ok with it provided it was done on the 1.5 trunk and not for 1.4
vmassol - (16/05/2008 16:22): I've read the comment
vmassol - (16/05/2008 16:22): but all I've seen is that it's "ugly"
vmassol - (16/05/2008 16:22): did we send an email to the fop project?
sdumitriu - (16/05/2008 16:22): No
vmassol - (16/05/2008 16:22): (or in their jira/bug tracker
vmassol - (16/05/2008 16:22): )
vmassol - (16/05/2008 16:23): so that they fix their pom
vmassol - (16/05/2008 16:23): we should probably do that in //
sdumitriu - (16/05/2008 17:30): vmassol: About the batik-rasterizer, should I submit a bug to the batik team, or can you ask somebody to post it there?
vmassol - (16/05/2008 17:34): sdumitriu: not sure I understand
sdumitriu - (16/05/2008 17:35): The problem is that batik-rasterizer-1.7 is missing from repo1.maven.org
sdumitriu - (16/05/2008 17:35): While all other modules are released
vmassol - (16/05/2008 17:36): we need to ask the batik team
vmassol - (16/05/2008 17:36): but in the meanwhile we can put it in our own remote repo
sdumitriu - (16/05/2008 17:36): Not sure how to obtain it
sdumitriu - (16/05/2008 17:36): The pom is somehow generated
sdumitriu - (16/05/2008 17:37): http://svn.apache.org/viewvc/xmlgraphics/batik/tags/batik-1_7/sources/batik-rasterizer.pom.template?view=markup
sdumitriu - (16/05/2008 17:38): So that's the pom, and we have the jar
