Provide an option to disable code highlighting auto-detect lacking lang

[hcoona]

Hi Sir,

I want an option to disable auto code highlighting, because I want the default behavior is not to highlight my quote blocks in my migrated articles. They are previously written in markdown language in Jekyll. The default behavior changed. I have to modify each blocks to add 'lang=plain' to avoid wrong highlighting. This block me from switching to the great hexo.

Thanks!

Edit _config.yml.

highlight:
  enable: false

Hi @tommy351 ,

Thanks for your answer. However I think it means not to highlight any blocks, that's not what I want.

I want to control the default behavior if there is no lang assigned to a code block. Currently hexo would make it auto-detect. I want to make it do not auto-detect and just make it plain.

Thanks.

I see. Hexo doesn't provide this option so far.

I modified the title to make it clearer.

Would be great to have this feature. Highlight.js is slow in auto detection.

Please consider to make it with high priority :)
It's not hard to add this option. Thanks!

Seems users need to add auto_detect: true to _config.yml manually when upgrading to 3.1.1, or else this option will be off by default.
