Ok I will send you that.

docx/odt are a zip which contains several XML entries (ex: for docx
word/document.xml, for odt content.xml)
XDocReport unzip docx/odt and load some XML entries ( word/document.xml,
for odt content.xml) with Freemarker.
So we have a Template instance for some XML entries. When report must be
generated, XDocReport uses Freemarker to merge
XML entries with Java context and create a new zip with XML entries merged.
Freemarker works great.

The only thing that I don't like is our extractor fields feature (it
extract Freemarker fields name from docx).See method extractVariables
https://code.google.com/p/xdocreport/source/browse/template/fr.opensagres.xdocreport.template.freemarker/src/main/java/fr/opensagres/xdocreport/template/freemarker/FreemarkerTemplateEngine.java

I find this code is awfull:

if ( DOLLAR_VARIABLE.equals( templateElement.getClass().getSimpleName() ) )

yes you are right, but it doesn't support OSGi.

cool.

Jonathan Revusky told me that it's possible to manage tolerant parser with
FreeCC, but he has gaven Freemarker.
I have not time to study FreeCC and I would like find people who are
interested to help me to develop DLTK Freemarker.

An other idea that I had had, is to manage Freemarker with CodeMirro(
Javascript editor which manages any mode). I have works a lot with
CodeMirror for completion and syntax error.
For instance you can find sample with Velocity
http://codemirror-java.opensagres.cloudbees.net/velocity.html the syntax
error is managed on server side. We could do the same thing with Freemarker
and better manage debugging feature.
