elisp - Emacs mode multiline comments -

What is the correct method to define multi-line comments in an emacs mode (Like C / / * / /)? The Ellisp example I see are for comments that begin with a delimiter and end at the end of the line (like C ++ 's // or perl's #).

It is such:

  (define-derived-mode my -Mod awk-mode "my" "my mode" (setq comment-multi-line zero); Maybe (setc comment-start "/ *") (set comment-end "* /"))  

but there are subtleties; Maybe you want

  / * line one * / / * line two * / / * line three * /  

or you want

  / * line one line two line three * /  

This is affected by your comment-style , which you can customize ( MX custom-variable comment-style ). For the first example, choose something like indent , for the second example, additional line .

All this is defined in newcomment.el , which you can read if you type Mx description-variable comment-start
