In fact, I don't understand why variables are not local by default in
velocity... I don't see any serious language where this is not the case...
ok velocity is not a language ;)

Vincent, this is not about macros, but about $variables used in
macros.
For example:
#macro(doSomething)
#set($a = 'b')
#end
#doSomething()
$a => prints b, $a is now a global variable outside the scope of the
macro. Pascal Voitot wrote:

Yes, I had my share of pain with the fact that variables defined
inside
macros are global... I am +1 for making them local, but all the
macros
should be checked, since some of them might use this "feature".
Velocity Macros *are* local (i.e. we're using the local macro
configuration option from Velocity).
<property>
<name>velocimacro.permissions.allow.inline.local.scope</
name>
<value>true</value>
</property>
However for the include feature of XWiki Syntax 1.0 to work we have a
hack in the velocity module to allow macros to span more than 1
document.
This is not required for the XWiki Syntax 2.0 (AFAIR) but we need it
for the 1.0 syntax to continue working.
oh ok. We can easily add a new parameter to the {{velocity}} macro (as
it's done for the {{include}} macro).
Do you mean you can modify the velocity engine config on the fly?
Thanks
