Re: [xwiki-users] Macro within code macro
Thanks Vincent/Thomas,
Just like Thomas mentioned, my intention was to execute a macro within
another macro so that I could "generate" the arguments for a macro on the
fly. We're using XWiki as a knowledge base/support tool at work, and we
encounter situations like this where we'd like to dynamically generate some
"text" as input for a macro.
The {{date}} macro is one example, but I was hoping to extend this to
extract other information for usage in other macros as well. Also, since we
depend on a (proprietary) Java API for calculating business dates, it's
easier for us to extract this info from a standardized Java macro than from
velocity or groovy.
Currently, we're only trying to utilize it with the {{code}} macro for
generating pretty copy/paste-able SQL and scripts, but we'd like to create a
completely new macro to execute SQLs/scripts on our production servers right
from the wiki (something similar to the SQL plugin for XWiki 1.x). Hope
this gives some background to the issue.
Again, thanks for the immediate feedback on this!

Well first we'd need to know why Lewis needs to do that!
I think we can rephrase the question as: how to pretty print a
generated text.
The general answer I think is:
{{velocity}}
## Compute the content here
#set ($content = "")
{{code language="java"}}
$content
{{/code}}
{{/velocity}}
As Thomas said though, if you want to execute wiki syntax from
velocity you can probably do something like:
#set ($mydoc = $xwiki.getDocument("dummy"))
$mydoc.setContent("{{mymacro/}}")
#set ($content = $mydoc.getRenderedContent())
Note that the current document in the xwiki context would still be the
current document and not "dummy" so any macro that uses the current
document would not use "dummy".
I'd like to know more about the use case.
Thanks

If by adding you mean execution it, then no it's not possible since
it's not the goal of the code macro. The code macro is supposed to
render its content as is without any interpretation (only syntax
coloring).
However if what you want is to execute some stuff you can use this
trick:
{{velocity}}
{{code}}
...
Some velocity code here that will be executed, including a velocity
macro
...
{{/code}}
{{/velocity}}

I think it's not exactly what Lewis asked. His problem is that he want
to execute a macro inside code macro so for that he need velocity to
generate the result of the macro in the code macro content and not
just the macro itself.
There is no easy way to do that in velocity, this means access the
parser as component execute it on {{date-macro date="-1b"
format="MMdd"/}}, execute transformations (other components) on it
and re-render the XDOM. And all that just to print a date if i
understood well your use case.

Hi xwiki-users,
Just wondering if it's possible to add a macro inside a code macro?
What I
want to do is something like this:
{{code language="sql"}}
select *
from xyz
where from_date = '{{date-macro date="-1b" format="MMdd"/}}' --
The
date-macro returns the last business date in MMdd format
{{/code}}

yes the velocity macro does this:
1) executes velocity on the full macro content which is considered as
text
2) run the wiki parser on the result

Thanks Vincent. One more question - is it possible to execute an XWiki 2.0
macro from Velocity context?

[xwiki-users] Macro within code macro
Hi xwiki-users,
Just wondering if it's possible to add a macro inside a code macro? What I
want to do is something like this:
{{code language="sql"}}
select *
from xyz
where from_date = '{{date-macro date="-1b" format="MMdd"/}}' -- The
date-macro returns the last business date in MMdd format
{{/code}}
Thanks in advance!
