[stringtemplate-interest] Region Syntax

Tue Sep 25 14:09:03 PDT 2007

I got this to work with the following, but run into a problem with group
formal args:

Layout.stg:
group layout;
main_layout() ::= <<
<html>
<head>
<title>
$@page_title()$
</title>
</head>
<body>
$@child_content()$
</body>
</html>
>>

Then the derived group, home.stg
group home : layout;
@main_layout.page_title() ::= "Homepage"
@main_layout.child_content() ::= "<h1>Welcome, $name$</h1>"

Setup code:
...
StringTemplate st = subgroup.GetInstanceOf("main_layout");  //subgroup
holding the group "home"

This line throws an exception because of formal arg checking :
st.SetAttribute("name", "Andrew");

Is there a way to set attributes in the "child_content" region?  The base
group file can't know all the possible attributes that might be needed for
@main_layout.child_content()

Thanks,
Andrew
