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

24 Jan 2017

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)
##

  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:%…

 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)

 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

...

 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.
