Can't get namespaces to work

[ringods]

In PR pattern-lab/patternlab-node#1135, I'm trying to replace node-twig with this twig library as the engine.

However, I can't seem to get the namespaces feature to work. Here is what I pass to Twig.twig() function:

{
  data: '{% include "@templates/03-article-2col.twig" %}\n',
  allowInlineIncludes: true,
  namespaces: {
    atoms: '/Users/ringods/Projects/personal/patternlab-node/packages/development-edition-engine-twig/source/_patterns/00-atoms/',
    molecules: '/Users/ringods/Projects/personal/patternlab-node/packages/development-edition-engine-twig/source/_patterns/01-molecules/',
    organisms: '/Users/ringods/Projects/personal/patternlab-node/packages/development-edition-engine-twig/source/_patterns/02-organisms/',
    templates: '/Users/ringods/Projects/personal/patternlab-node/packages/development-edition-engine-twig/source/_patterns/03-templates/',
    pages: '/Users/ringods/Projects/personal/patternlab-node/packages/development-edition-engine-twig/source/_patterns/04-pages/',
    macros: '/Users/ringods/Projects/personal/patternlab-node/packages/development-edition-engine-twig/source/_macros/'
  },
  id: 'pages-article'
}

But I get this as result:

Error parsing twig template pages-article: 
TwigException: Unable to find template file @templates/03-article-2col.twig. Error: ENOENT: no such file or directory, stat '@templates/03-article-2col.twig'

In the namespaces configuration, I tried to pass both absolute and relative paths but neither of the two seem to work for me.

@RobLoach sorry to ping you here directly. I am sort of stuck on this. At first sight, do you have any idea if I am missing something in how I call twig?

Closing since the original PR referenced did not end up using this library. If any one else encounters this issue, please provide a simple, reproducible example of it not working as expected.

I can reproduce this as well...

Project structure:

_folder
__test.twig
_build.js

test.twig

Hello from twig

build.js

const Twig = require('twig');

const html = Twig.twig({
  data: "{% include '@my-project/test.twig' %}",
  allowInlineIncludes: true,
  namespaces: {
    'my-project': 'folder/',
  }}).render();

console.log(html);

Console output:
