TIL: 2 extra comment-dwim features

Today I just learned (by accident) a couple of tricks related to`comment-dwim'. The emacs command is bound to M-; , and it has different behaviours  depending on the line, region, and contents of the selection.

Appart from the ovbious behaviour we all know, today I found that:

  • Called with universal argument in an empty line, it adds ARG comment markers in the line. try C-u M-; in an empty line.
  • In a line with comments, c-u m-; removes the comments. that means deleting the comment, NOT UNCOMMENTING but removing all commentted text and the comment marker itself.

    Thanks for sharing that. Here's the function I've been using lately: https://gist.github.com/alphapapa/97642ff798f773f48af4dd5c20f4854f
