Having a path in config.new_post_name breaks tag plugin post_link

[kristofzerbe]

Check List

• I have already read Docs page & Troubleshooting page.
• I have already searched existing issues and they are not help to me.
• I examined error or warning messages and it's difficult to solve.
• I am using the latest version of Hexo. (run hexo version to check)
• My Node.js is matched the required version.

Expected behavior

My post folder structure relies on subfolders per year, like _posts/2023/my-fancy-post.md, with asset folders of the same name, and I use the Tag Plugin post_link in many posts.

Since hexo new post XXX always creates the new post in the root post folder, I recently changed the config entry new_post_name from :title.md to :year/:title to create the new posts directly in the correct folder.

I expected that the new post is created in the appropriate subfolder (works) and Hexo generates my files (works not)

Actual behavior

After the change my build, which executes hexo clean && hexo generate, aborts with the following message:

Template render error: (unknown path)

The error occurs comprehensible in Hexo 6.3.0 as well as in 7.0.0. :title = generation works, :year/:title generation stops with error.

How to reproduce?

1. Clone https://github.com/kristofzerbe/kiko.io
2. Edit /_config.yml with new_post_name: :year/:title.md
3. Run hexo generate

Is the problem still there under Safe mode?

Others

I was hoping issues like #5042 would help me, but that wasn't the case

[kristofzerbe]

same with #4778

[kristofzerbe]

One more thing, I didn't mentioned: The post_link's in my MD's are looking always like this:

{% post_link 2023/My-fancy-post %}

... as Steven pointed out in #5042 (comment)

[D-Sketon]

It seems that if you change the config entry new_post_name from :title.md to :year/:title.md, you need to remove the subfolder prefix in post_link like {% post_link My-fancy-post %}

[kristofzerbe]

Oh yes, you're right. Works, even if I couldn't directly establish a connection between the config entry and the tag in my head and in the code.
