 Note that if you are
 using XWiki 8.3+ you don't need to go trough
 xcontext to pass data between velocity macro
 and other script macros.
 Velocity variables
 ends up in Groovy (as global variables) and the
 opposite.

Re: [xwiki-users] How to sort hashmap with velocity?

[Pascal BASTIEN]

Ok, then I inesert groovy code between 2 velocity bloc to sort my map:

...
  #end ##Fin foreach
  $xcontext.put("xSiglesArray", $SiglesArray)
  
#end ## fin temporaire pour insérer le code groovy
{{/velocity}}

{{groovy}}
if(xcontext.get("xSiglesArray")){
  SiglesArrayGv = xcontext.get("xSiglesArray");
  // Trie le tableau (insensitive case )
  SiglesArrayGv=SiglesArrayGv.sort { it.key.toLowerCase() };
  xcontext.put("xSiglesArray", SiglesArrayGv);
  xcontext.put("DoRegen", true);
  }
{{/groovy}}

{{velocity}}
##
##Regénére la page et trie les entrées (suite)
#if ( $xcontext.get("DoRegen")== 'true' && $xcontext.get("xSiglesArray") )
##
  #set ($SiglesArray= $xcontext.get("xSiglesArray"))
  #foreach($Anchor in $AnchorsArray)

 Velocity is very far from supporting Java
 syntax. Plus here you seems
 to be mixing
 CollectionsTool and TreeMap javadoc. CollectionsTool
 contains only one getSortedMap() method and it
 has no parameter.
 
 There
 does not seems to be any way to get a TreeMap configured
 with
 String.CASE_INSENSITIVE comparator in
 Velocity. The main issue is that
 you
 can't create an object or access a static variable in
 Velocity so
 no way to use a method that
 takes a Comparator as parameter even if
 there was one (which is not the case for
 maps).
 
 Right now the only
 alternatives seems to be:
 * use Groovy
 * write a script service in Java that provide
 the feature
 * patch CollectionsTool to add a
 way to pass a comparator to the various methods

Velocity is very far from supporting Java syntax. Plus here you seems
to be mixing CollectionsTool and TreeMap javadoc. CollectionsTool
contains only one getSortedMap() method and it has no parameter.

There does not seems to be any way to get a TreeMap configured with
String.CASE_INSENSITIVE comparator in Velocity. The main issue is that
you can't create an object or access a static variable in Velocity so
no way to use a method that takes a Comparator as parameter even if
there was one (which is not the case for maps).

Right now the only alternatives seems to be:
* use Groovy
* write a script service in Java that provide the feature
* patch CollectionsTool to add a way to pass a comparator to the various methods

[xwiki-users] How to sort hashmap with velocity?

[Pascal BASTIEN]

Hello,

with velocity I have a hashmap: sort of variable with (key:value) that I want 
to sort, then I use:
#set ($myHashMap = $collectionstool.getSortedMap(String, String))
$myHashMap.put('Mykey3','My value 3')
http://platform.xwiki.org/xwiki/bin/view/ScriptingDocumentation/?url=http:%2F%2Fnexus.xwiki.org%2Fnexus%2Fservice%2Flocal%2Frepositories%2Fpublic%2Farchive%2Forg%2Fxwiki%2Fcommons%2Fxwiki-commons-velocity%2F8.2.1%2Fxwiki-commons-velocity-8.2.1-javadoc.jar%2F!%2Forg%2Fxwiki%2Fvelocity%2Ftools%2FCollectionsTool.html%23getSortedMap--

It's working well ... except with uppercase because I want a sort with 
insensitive case.

I tried to decrypt Javadoc and I found I could use: 
String.CASE_INSENSITIVE_ORDER
#set ($myHashMap = $collectionstool.getSortedMap(String.CASE_INSENSITIVE_ORDER, 
String))
#set ($myHashMap = $collectionstool.getSortedMap(String::compareToIgnoreCase, 
String)) with java8
but unfortunaly it doesn't work (I have xwiki error)

Any idea to sort my hashmap with with insensitive case?

(Unfortunaly the better way I found is an ugly way: I mix velocity with a piece 
of groovy but I'm not satisfied at all because I use velocity loop and other 
if.)

Thxs for any help.
