@bengreeley I looked at this issue and I don't think changing those functions is the way to go. I followed your suggestions, installed a child theme, and broke the site due to core.php not loading properly on the parent theme in the functions.php file.

I started a pull request for this issue at #50 with my suggested changes. So far I am following the naming convention for script and style handles set by the 10up-plugin so that the child theme can load the parent styles properly as noted in the Core handbook. Feel free to send me some more direction and I can try to implement it.

@bengreeley After thinking about this more today, you are saying the scaffolded theme should be able to be used as a child theme. I read it as the scaffolded theme is the parent theme and then support needs to be added to then layer a child theme on top. I'll do some testing for both scenarios and put it into my PR.

Hey @claytoncollie thanks so much for putting this PR together! I found some issues with it, which I'll log below. For my testing I cloned your branch and grabbed the theme folder and added * Template: twentytwenty to style.css to be a child theme of TwentyTwenty.

Issues:

• When activating the child theme I get an error failed to open stream: No such file or directory in /var/www/html/wp-content/themes/10up-theme/functions.php on line 17. What it looks like is going on is the variable TENUP_THEME_INC is using get_template_directory(), which refers to the main parent theme. If we use get_stylesheet_directory() instead it should resolve it and refer to the child theme.
• Likewise, TENUP_THEME_TEMPLATE_URL is set to use get_template_directory_uri(). We'll probably want to consider using get_stylesheet_directory_uri() instead so it'll refer to the child theme files.
