[stringtemplate-interest] How to call a template from another when using formal args

[Marziou, Gael]

Thanks for your reply. 

Equals is not a reserved word, however some of your suggestions helped me to find a solution inspired by testFormalArgumentAssignmentInApply().

The trick was to use $it$.

String templates = 
		"group test; " +
		"zero(var) ::= \"$var:equals(value=0)$\" " +
		"equals(value) ::= \"$it$ = $value$\"";


However, when I tried to use 2 formal arguments it did not work:

String templates = 
		"group test; " +
		"zero(var) ::= \"$equals(var=$var$, value=0)$\" " +
		"equals(var, value) ::= \"$var$ = $value$\"";

Then I tried to pass a constant string, still no luck:

String templates = 
		"group test; " +
		"zero(var) ::= \"$equals(var=\"a\", value=0)$\" " +
		"equals(var, value) ::= \"$var$ = $value$\"";

So I switched to "<< >>" syntax and it worked:

String templates = 
		"group test; " +
		"zero(var) ::= <<$equals(var=\"a\", value=0)$>> " +
		"equals(var, value) ::= <<$var$ = $value$>>";

I guess there is something fundamental that I did not get on passing arguments because it does work easily when I am just passing integers.
Something wrong probably with quoting.

String templates = 
		"group test; " +
		"zero(var) ::= \"$equals(var=1, value=0)$\" " +
		"equals(var, value) ::= \"$var$ = $value$\"";


Thanks,
