Emacs Asked on November 30, 2021
New Emacs user here. Hitting enter after a semicolon commented line in any file type (.el and .lisp at the very least) indents the comment in a very unhelpful way that I have to assume is not intended behavior. This problem does not occur if I move away from that comment line in any way besides hitting return (triggering auto-indent presumably).
For example, If I type the following
; this is a comment
Then hit return, I get the following (32 spaces indentation)
; this is a comment
What is causing this behavior, and how can I prevent it?
I am running Emacs 26.3.0.20191219 installed through Chocolatey on Windows 10
Unable to post this as a comment, but the indentation is likely part of one of the active modes (probably lisp-mode
based on your description).
You can do M+x describe-modes
to see which modes are active.
This answer provides some background on the history of the common lisp commenting style https://stackoverflow.com/a/6365579
This question and answers describe why the single ;
indents differently than multiple consecutive ;
characters: https://stackoverflow.com/questions/14190488/set-comments-at-the-same-indentation-level-as-all-forms, namely that lisp-indent-line
hardcodes it with the following comment
;; Single-semicolon comment lines should be indented
;; as comment lines, not as code.
