Sorry, this lib can not do this.
It's just convert markdown to html.

And line number may be use css or js?

Line numbers in code blocks can be done using css. See https://codepen.io/elomatreb/pen/hbgxp or https://www.sylvaindurand.org/using-css-to-add-line-numbering/ for two examples (although they are essentially the same) of implementations.

Thanks man, it looks pretty good, but when I try to select the code in multiple lines, the numbers are also selected, and when I copy and paste the code, every empty line become two empty lines.
They look like

def print_hi(name)

	puts "Hi, #{name}"

end


print_hi('Tom')

#=> prints 'Hi, Tom' to STDOUT.

Perhaps it would help to give you a single, self-contained example. So I made a self-contained example on my side website. Perhaps it makes more sense now?

Yeah, it really helps a lot.
Much appreciated
