Hexo-theme-next: auto_excerpt not working as expected

[khoint0210]

I agree and want to create new issue

• [x] I have confirmed that this bug only appears in theme NexT, but cannot be reproduced in other themes (e.g. default theme landscape). In other words, prove that this is a NexT bug, not a bug from Hexo.
• [x] I have already viewed Hexo Docs page, especially Templates, Variables, Helpers and Troubleshooting.
• [x] I have already viewed NexT Documentation Site.
• [x] I have searched for current issues which does not help me.

---

I'm unable to use auto_excerpt even setted to true I don't want to use <!-- more --> in my article

Expected behavior

Should auto excerpt but not

Actual behavior

Steps to reproduce the behavior

1. N/A
2. N/A
3. N/A

• Link(s) to source code or any usefull link(s): N/A

[khoint0210]

@stevenjoezhang thanks a lot, that plugin works.
I'm using Latest Master branch, i'm sure it is 7.5.0, not 7.6.0.
auto_excerpt seems to be removed from next/_config.yml, certainly add these configuration below to _data/next.yml not works.

auto_excerpt:
  enable: true
  length: 150

[stevenjoezhang]

I'm sure it is 7.5.0, not 7.6.0.

Because the master branch is the development branch. We update the version number with each release. So after December 1st you will find this is the 7.6.0 version 🤪
