Is this a bug, the esoteric Elisp way?

🖖 Hello World,



Goto `emacs -Q -nw`, type ";\r", or ";\n", and it indents the semicolon (alot); how do I stop this?

Disable electric-indent-mode.

Type ";;\n" instead.

PS:



I just figured it out; it's the Elisp way!



/^;[^;]/ is not the Elisp way ∵ *scratch* only has /^;;/, and there's some esoteric law about /[^;];[^;]/ only being inlined after an instruction, reminiscent of the syntax of C; 'tis the UNIX way, reminding us the Elisp Machine Accumulates C Supplements.



So `(setq electric-indent-mode nil)` disables it, and I thought it also disables all tabbing; this seems disabled in Elisp, but not plain text files, and http://ergoemacs.org/emacs/emacs_tabs_space_indentation_setup.html patches it. The documentation for electric-indent-mode says "If called from Lisp, enable the mode if ARG is omitted or nil.", but nil disables it; /implementation|typographical/ bug. Someone at #emacs mentioned electric-indent-mode, but my browser crashed, and webchat doesn't have private logging (into
 web storage on the client side; please make this happen, but I won't 
need it when I learn ERC; which hopefully shouldn't be long from now).



Anyway, this is probably a bug; goto `emacs -Q -nw`, type ";\t", and it indents the semicolon (alot); how do I stop this?

The documentation you refer to is about the function, i.e.,
`(electric-indent-mode)` or `(electric-indent-mode nil)` will enable
the mode. Use `(electric-indent-mode -1)` to disable it.

Using setq on the variable won't do the right thing, as mentioned in
its documentation:

Setting this variable directly does not take effect;
either customize it (see the info node ‘Easy Customization’)
or call the function ‘electric-indent-mode’.

🖖 Hello Noam,



Thanks, I've changed it in my init.el file, but the way I was doing it before also worked; `C-h f electric-indent-mode` in 26.1 doesn't include any of that for me.

Try `C-h v electric-indent-mode` to see the variable documentation, or
`C-h o electric-indent-mode` to see both.

🖖 Hello Noam,



I meant all tabbing is disabled in Elisp, but not plain text files; thanks for the *Help*.
