[stringtemplate-interest] List construction as argument

[Dennis Waldherr]

Hi,

I have a problem with using a list generated by the "[...]" operator. I
tried to set an template argument directly with a generated list. Then I
tried to acccess the list twice in that template, which didn't work.

I'm using stringtemplate-3.0 and here's a group file which fails to
deliver the result I expected:

group simple;
f1() ::= << <f2(["a", "b"])> >>
f2(x) ::= << <x> <x> >>

I'm new to using stringtemplate so I might have made an error here, but
it doesn't print any warning/error messages so I hope that is "good enough".

Java version of this:

public void templateTest() {
	String templates = "group simple;" +
		"f1() ::= << <f2([\"a\", \"b\"])> >>" +
		"f2(x) ::= << <x> <x> >>";
	// Use the constructor that accepts a Reader
	StringTemplateGroup group = new StringTemplateGroup(
		new StringReader(templates));
	StringTemplate t = group.getInstanceOf("f1");
	System.out.println(t);
}



I expected to get "ab" twice in my output, but I only get it once.
Placing more <x> doesn't change anything so I guess the first one
somehow "consumes" the list (which would seem to be a strange side
effect, at least to me).

"Help meeee" :)

Greetings,
Dennis
