Pasing argument to partial template (#def) ?

[jeme]

In the advanced examples you define a snippet like:

{{##def.snippet1:
    Some snippet that will be included {{#def.a}} later {{=it.f1}}
#}}

I was wondering if it was at all possible to substitute "it" for that snippet.
Given the following example:

{{##def.row:
{{=it.Title}}
#}}

<ul>
    {{~ it.Nodes :p}}
    <li>
        {{#def.row}}
        <ul>
            {{~ p.Nodes :s}}
                <li>
                {{#def.row}}
                </li>         
         {{~}}
         </ul>
     </li>
     {{~}}
  </ul>

Now the idea would be to print "p.Title" for the first level and then "s.Title" for the second level, but re-use the same template for both elements...

Also would it be possible to make the above recursive somehow?

There is no parameter passing right now for defines. There are 2 other ways to get this kind of functionality though.

1. You could create a variable like {{ var x; }} and assign it some value before including def, like
   {{ x=s; }} {{#def.row}} and in def row use x instead of it.
2. Another way is to use function instead of def like this:
   {{ function row(x) { }}
   Some snippet that will be included {{#def.a}} later {{=x.f1}}
   {{ } }}

and then instead of {{#def.row}} call {{ row(s); }}

For recursion you can do this:

{{ function children(it) { }}

{{?it.Nodes && it.Nodes.length}}
<ul>
    {{~ it.Nodes :p}}
    <li>
        {{=p.title}}
        {{children(p);}}
    </li>
    {{~}}
</ul>
{{?}}

{{ } }}

{{ children(it); }}

Hey THANKS!..

I ended up with a solution like you describe in "1." yesterday, where the reused template was also stored else where as it's own template though. But I think I like the idea of using a function better, so ill try to get that into place.

Thanks Tomasz. I will push support for passing arguments to defines very soon.
For using functions, see #34 (comment)

well, it would be great to have a support for passing arguments to defines / functions

or is there any other option to use some kind of universal functions that would format the given variable, no matter the variable name ( quick use-case: number 'prettifier' )

otherwise all the templates become non-DRY really quick...
