Re: [xwiki-users] Using a local class within a wiki page
Ok I’ve discussed with Guillaume Laforge from Groovy fame and here are more
details:
* In our code we capture the output of the script and use it to display the
rendered page so any println located directly in the script will work.
* However for a println in a Class, Groovy call System.out.println(…) - which
is why it goes in the xwiki logs - and we would need to capture that in a
thread safe way to redirect it to the page rendering this is a bit more
involved:
** Use System.set(PrintStream) with a custom PrintStream that would use for
example a threadlocal variable to direct the content to our page being rendered
** Use Groovy’s runtime metaprogramming feature, for example:
PrintStream.metaClass.println = { String s - ...handle thread safety here.. }.
** Use Groovy’s compile-time metaprogramming feature and implement a Groovy AST
Transformation to transform all println calls into something else. For example
by adding a binding to the ScriptContext and using that binding instead of
println. This requires using a CompilationCustomizer (we already do that in
XWiki btw) which returns an ASTTransformationCustomizer to do the work.
Thanks

Actually the message is printed in the console.
You see something in the page only if you print in the global scope because
this is what gets returned by script evaluation. Calling “println” in a
class
doesn’t return anything in the evaluation and thus you don’t see anything.
That’s why the examples at
http://extensions.xwiki.org/xwiki/bin/view/Extension/Groovy+Macro work.
Right, makes sense. So looks like the best fix is to return the string and
print it from global (script) scope. This works:
{{groovy}}
class Callee {
def hello() {
return hello, world
}
}
c = new Callee()
println c.hello()
{{/groovy}}

Re: [xwiki-users] Line wrapping in Code Macro
This is because that's actually what you asked with this syntax. To customise the macro itself you can use cssClass parameter, see http://extensions.xwiki.org/xwiki/bin/view/Extension/Box+Macro#HParametersdefinition (code macro inherits box macro).

That was my first thought, but here's the weird thing: when I add CSS styles that way, the code block ends up getting rendered as a paragraph (P tag) with the style applied in a SPAN, instead of being rendered in a DIV as it normally is. This changes the look completely, and with forced line breaks it gets quite messy. But since the macro has a place to specify a CSS class, I guess I could just create a class to handle the line breaking. I'm still pretty new to Xwiki, can you tell me what best place/way is to add a CSS class that I can use on any page?

[xwiki-users] Migrate MediaWiki content to XWiki
Hi all, I’m trying to get us migrated from several installations of MediaWiki to one XWiki. I have installed XWiki 6.3 just fine… but the big problem is migrating the data over. So far all the options I’ve found have been sorely lacking. -The method provided on the Encodo blog, uses the XMLRPC API which has since been deprecated -The Mediawiki to Xwiki Migration Toolkit requires setting up an entire development environment with a special customized version of XWiki just to do the import, which is unnecessarily complex and error-prone. -A few other methods which may work, but omit portions such as history. Is there a relatively simple batch import mechanism that works with the current versions of xwiki, or am I relegated to importing stuff manually? I *could* write my own import tool, but if I have to go that route we may as well just do it manually because we will need to audit and clean up the articles anyway.

Re: [xwiki-users] Run external script to generate data for wiki page
I was thinking basic current side AJAX, rather than doing something server side in Velocity. It's not my area, but I'm sure it's possible.

Essentially, what I want to do is have a page / form that my users fill out and then submit. Upon submit I need to invoke an external script (e.g..Perl, Python, VBScript, Batch etc...) that will do some quick data gathering then insert some data in a database. Once the script generates the data the page will then retrieve it and render some results based on it. Most of the mechanics I can figure out I think, but I wanted to get some tips on the best way to actually invoke the script from a page in Xwiki.
