Hello,
To customize our entreprise wiki, we have identified a few plugins /
macros that we need to develop. I have checked the online xwiki
documentation / tutorial, but i find them quite uncomplete, so here i am
with my questions :)
1) It is my understanding that, if my macro need some specific javascript
(eg jquery.js) and css, i must use xwiki skin extension. While i can find
easily how to create xwiki velocity code that use those extension, i found
no explanation on how to do this in java from within "public List<Block>
execute(T parameters, String content, MacroTransformationContext context)"?
Where can i find example of embedding javascript/css inside a java macro jar
or xar?
You declare a dependency on the org.xwiki.platform:xwiki-platform-skin-api
module in your project, and you declare a dependency on one or more
org.xwiki.skinx.SkinExtension fields with the right hint. For example:
@Inject
@Named("jsrx")
private SkinExtension jsrx;
Then you can call jsrx.use("jquery.js") if that file is packaged as a
resource whenever your macro is used.
If you'r
2) Extensions are provided as xar, maven
archetype for xwiki java macro
generates a .jar. How do i generate a xar with maven so that in one archive
i have both my macro, the css and the js?
Not true, extensions can be both jars or xars, depending on what kind of
extensions they are. If you're deploying a java macro, then it's right to
have a jar extension. A xar is used when you're providing wiki documents
that should be installed in the wiki.
3) Most extension referenced on xwiki main site
are open source, but where
are the source? I can only find the compiled xar files on download
A xar is just a zip file holding wiki documents, and you can always edit
those wiki documents to see their "source". A xar is both the source and the
binary.
Some extensions do have a separate link to a repository if they have one,
especially those hosted on the official xwiki or xwiki-contrib repositories.
4) Is there some recommanded way to pass complex
parameters to macros? I
need to create some dynamic menu that will get as parameter a list of node +
links + icon to show + subnodes + for each subnodes icons / links +
subsubnode etc. Is it good practice to just put some kind of json in the
body of macro, something like
{{mymenu width="200px"}}
[
{ name: "node1", link: "MySpace.MyPage1", icon:
"somelinktoanattachement"}
,
{ name: "node2", link: "MySpace.MyPage2", icon:
"somelinktoanattachement"},
{ name: "node3", link: "MySpace.MyPage3", submenu: [
{ name: "node3.1", link: "MySpace.MyPage31", icon:
"somelinktoanattachement"},
{ name: "node3.2", link: "MySpace.MyPage32", icon:
"somelinktoanattachement"}
]
}
]
{{/mymenu}}
Unfortunately, macro calls are in text mode, so you don't have much of a
choice.
You could define a variable somewhere in Velocity and then read it in Java
from the VelocityContext, but that's not very safe and might break in the
future.
And in this case, are there already some stock
xwiki methode to transform
json into objet array?
I'm not sure of the status, but there was a proposal recently to include a
JSoN tool in the platform. I think it wasn't committed yet,
Reading from http://markmail.org/message/k4izx6re4lvdynx3 I think that you
should use the Jackson library, available as a maven dependency from
http://search.maven.org/#search|ga|1|a%3A%22jackson-core-lgpl%22
Thank you,
David Delbecq
