Math script loaded in tags and archives pages [solved]

[wafer-li]

I agree and want to create new issue

• Yes, I was on Hexo Docs page, especially on Templates, Variables, Helpers and Troubleshooting.
• Yes, I was on NexT Documentation Site.
• And yes, I already searched for current issues and this is not help to me.

Expected behavior

Math script won't be loaded with no math in tags, achives pages etc.

Actual behavior

Math sript loaded in tags, achives pages etc. even if there is no math in homepage.

Steps to reproduce the behavior

1. Turn on enable of math
2. hexo clean && hexo g -d

• Link to demo site with this issue: https://wafer.li/
• Link(s) to source code or any usefull link(s):
  

  hexo-theme-next/layout/_third-party/math/index.swig

  Line 2 in bf6d324

  {% if not theme.math.per_page or (page.total or page.mathjax) %}

This line, for now, per_page default to true, then not theme.math.per_page will befalse.

And if we are at homepage now, page.total will be true, therefore even if page.mathjax is false, the(page.total or page.mathjax) still be true.

Finally, after those determinations, the if not theme.math.per_page or (page.total or page.mathjax) will return true and load the math script.

Since the tags and achives pages has the post.total property, and it will load the math script in tags and achives pages.

And there is the screenshot:

Should be loaded in homepage, to make sure if there is any posts would use it.

Yeah, but in the Archives, Tags, About, etc. seems need to add some additional conditions to determine if it is needed.

@tsanie
I found useful Hexo Helper which could determine is_home(), is_tag() etc.

OK, I understood, it does need to render math on the homepage.

It seems that Muse theme display the whole post on the homepage by clicking the Read More button?

Will fix it ASAP

Maybe provide some new configs to allow the user load math in tags and archives pages.
@tsanie @iissnan

Such as:

# Math Equations Render Support
math:
  enable: true

  # Default(true) will load mathjax/katex script on demand
  # That is it only render those page who has 'mathjax: true' in Front Matter.
  # If you set it to false, it will load mathjax/katex srcipt EVERY PAGE.
  per_page: true
  
  tags_page: false
  achives_page: false

  #engine: mathjax
  engine: katex

@wafer-li emmm, I think user could switch their config by the tags, archives page's front-matter, like the normal post page.

Just treat the tags, archives, abouts pages as the normal page, I think it's better.

Only the homepage is the special one.

@tsanie
OK, that might be better.
