@skuzzymiglet do you have some repo with the code to see what's going on there?
i have come across the same problem. seems like Liquid::Block does not provide the render_all method anymore. Even the regular Liquid::Block::render() method is marked "For backwards compatibility". Likewise, the whole API for liquid blocks has changed.
I will have a more in-depth look into the problem, but never having wrote a liquid/jekyll module myself, it will not be very successful, i fear.
For a simpler version that works well with the built-in for block and works with current versions of liquid, see https://gitlab.com/baldrian/klimacamp-augsburg/-/blob/91244ae327380714e6d62778598a4bc69917c557/_plugins/list_files.rb. It creates a Page object for each of the files that were found, so if you don't want that, remove the .map do ... end part (you can also remove the site = ... and source = ... lines as well as the comment in that case) – without the map call, you'll get a list of filenames instead of a list of pages. See https://gitlab.com/baldrian/klimacamp-augsburg/-/blob/91244ae327380714e6d62778598a4bc69917c557/feeds/pressemitteilungen.xml#L14-15 for an example usage.
I can't seem to get it work.
my directory for the image folder is /images under root directory.
The frontmatter in the post, I have "photos: /images"
and in my layout html, I have:
{% loop_directory directory: {{ page.photos }} iterator:image filter:*.jpg sort:descending %}
<img src="{{ image }}" />
{% endloop_directory %}
but nothing's showing. What did I do wrong?
@meiadvanture this is like 8 years old or more, try this tho:
{% loop_directory directory:images iterator:image filter:*.jpg sort:descending %}
<img src="{{ image }}" />
{% endloop_directory %}
Not sure about your {{ page.photos }} try it without that first and see.
I get a
