the same way=because (the way to support it is completely different
that the way to parse macro content ;))

So }} is not allowed in a macro parameter. Otherwise there would be a
pb to know which "}}" correspond to the macro end (it would be harder). Hi xwiki-users,
One small quirck with the 2.0 release - when I try something like
this:
{{box title="{{info}}test{{/info}}"}}this is a test{{/box}}
the output becomes a bit screwey... Parts of the {{info}} tag gets
added to
the content of the box instead of into the title. It does work
when the
{{info}} is escaped properly:
{{box title="~{~{info~}~}test~{~{/info~}~}"}}this is a test{{/box}}
but the WYSIWYG editor doesn't escape these (and it would make
things look a
bit nicer if we didn't have to escape on properly-quoted
parameters.. with
the obvious exception of a double-quote inside a quoted-
parameter :-)).
So... what should the right behavior be?
IMO there shouldn't be any need for escaping the { and } inside a
parameter value. It seems the XWiki 2.0 parser stops reading the
parameter value when it encounters }} which I think it's a bug.
Thomas should know more about it.
BTW you only need to escape one "}" to make it work fine ;)
Note that quotes for macro values are optional right now and this is
the reason macro params are checked for }}.
We could support it, it's not a good reason. It's not a big difference
to support with or without the quotes. The hard part is the refactor
needed to actually parse the macro parameters in javacc directly
instead of after the javacc pass.
We could decide that quotes are mandatory but it's a pretty big change
-1 for that, i'm pretty sure most of the users don't use the quotes.
It would just be more pain for the user. It's a wiki syntax not hidden
serialization format.
(would be for Syntax 2.1) and I don't think
it's a good idea since
this your use case is pretty rare. And btw I still don't know if
accepting wiki syntax in parameters is a good thing or not.
Thanks
-Vincent
