AWS template documentation help

[Michael Hardeman]

Running this code:

Templates.Set_Tag_Separators (Start_With => "'@", Stop_With => "/");
Templates.Insert (Translations, Templates.Assoc ("foo", "'bar/baz"));
Put_Line (Templates.Translate ("test '@foo/one/two/three' test", Translations));

Yields the following error:

raised TEMPLATES_PARSER.TEMPLATE_ERROR : Unknown attribute name "@foo"

I expected it to print:

test 'bar/baz/one/two/three' test

If I remove the initial ' in Start_With it works ok, but if I keep the ' I get this strange error. I assume there might be some undocumented feature for the templates, but I can't find anything having to do with "attribute". Does anyone know what this is?

Well, first let's simplify. Try replacing the tag-separators with something unique:
 Templates.Set_Tag_Separators (Start_With => "[[", Stop_With => "]]");
and matching alterations in the translation:
 Put_Line (Templates.Translate ("test '[[foo]]/one/two/three' test", Translations));

See if that helps.

I have done that, 

It works with other delimiters, but when the Start_With starts with ' it seems to fail.

The problem I'm really solve is creating a modern Single Page App, that's served and built in AWS. I'm using polymer 3, they do some very funky stuff. when It's served via the polymer-cli's "polymer serve" command, all javascript module paths that start with @ are served to the browser modified.  

for example:
import { PolymerElement, html } from '@polymer/polymer/polymer-element.js';

is modified to
import { PolymerElement, html } from 'node_modules/@polymer/polymer/polymer-element.js';

So in order to emulate this, I need to replace '@polymer/ with 'node_modules/@polymer/

So I could make the Start_With => @, which works, but the problem is that's not unique enough. There is an @license comment at the top of their source code that causes AWS to throw an error for non-terminated templates.

Why not just use the default ones "@_"  and "_@" ??
/P

Because I need to serve code I did not write, that is obtained automatically.
