Java StringTemplate Using File From Outside Directory
Question
I have a directory structure like this:
Templates/
├── Foo/
│ ├── Foo.st
├── Signature.st
Here's what the Foo.st looks like:
<?xml version="1.0" encoding="UTF-8"?>
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
<head>
</head>
<body>
<div id="body">
<p> Some Text </p>
</div>
$Signature()$
</body>
</html>
Here's my Java code with StringTemplate :
STRawGroupDir dir = new STRawGroupDir("Templates", '$', '$');
ST st = dir.getInstanceOf("Foo/Foo");
System.out.println(st.render());
But the output is:
<?xml version="1.0" encoding="UTF-8"?>
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
<head>
</head>
<body>
<div id="body">
<p> Some Text </p>
</div>
</body>
</html>
How do I get the Foo template to be able to properly reference the signature template?
If I put Signature.st inside the Foo directory then the above code works just fine, but I can't do that as I'll have many templates that will reference the Signature template.

Try:
...
$/Signature()$
...
Template calls are resolved relative to the calling template. Starting a template call with prefix / will make the template call absolute - which is what you expect.

I figured out a really easy way to do this. I have now the following directory structure:
Templates/
├── Foo/
│ ├── Foo.st
├── Main.st
├── Signature.st
Here's my Main.st
$ templates : { template |
$(template)()$
}$
$Signature()$
And here's my java code:
STRawGroupDir dir = new STRawGroupDir("Templates", '$', '$');
ST st = dir.getInstanceOf("Main");
st.add("templates", Arrays.asList("/Foo/Foo.st"));
st.render();
Now I can pass in any number of templates and this works perfectly.
