Theme inheritence not working?

[rbukovansky]

I'm trying to follow https://learn.getgrav.org/themes/customization#theme-inheritance as I'm trying to enhance theme knowledge-base with updates our company needs, but I'm getting this error:

Whoops \ Exception \ ErrorException (E_ERROR)
Class 'Grav\Theme\KnowledgeBase' not found

My theme files:

blueprints.yaml:

name: NETTO Knowledge Base
version: 0.0.1
description: "Extending Knowledge Base theme"
icon: crosshairs
author:
 name: Richard Bukovansky
 email: [email protected]
 url: https://github.com/rbukovansky

netto-knowledge-base.php:

<?php
namespace Grav\Theme;

use Grav\Common\Theme;

class NettoKnowledgeBase extends KnowledgeBase
{
   // Some new methods, properties etc.
}
?>

netto-knowledge-base.yaml:

streams:
 schemes:
   theme:
     type: ReadOnlyStream
     prefixes:
       '':
         - user/themes/netto-knowledge-base
         - user/themes/knowledge-base

Anybody has an idea, what could be wrong? Thank you.

Ad netto-knowledge-base.php: I'm getting same error no matter if there is or is not this line:

use Grav\Common\Theme;

I'm sure it has something to do with the hyphenated file name. I see this mentioned in the forum, but no solution is given. I didn't think I could simply rename my php file knowledgebase.php and it still work.

[rbukovansky]

Well, I have removed dashes from files and folders names and any mentions in .yaml files for these themes and guess what? It really works... Huh...

[Perlkonig]

Does it really work, though? This theme doesn't have anything in the PHP file, but if it did, would it still properly inherit? No thrown errors is one thing, but that doesn't mean it's working as it should.

Ok, sorry this took so long, should be sorted with last commit.

[rbukovansky]

@Perlkonig Yup, it worked...

@rhukster That's OK, and I can confirm, that change makes my Grav installation with inherited theme work again. Thanks!
