how to insert single quotes around a command?

how to insert single quotes around a command?

[Seweryn Kokot]

Hello,

Many times when I write doc strings for elisp functions I forget to insert
single-quotes around commands or variables like `a-command' or insert it
wrong like 'a-command'. Is there a function or keybinding to do it
properly? Maybe a function which enclose a selected command with
single-quotes?

Thanks in advance.

I'm using:

(defun insert-hyphen-or-two ()
   (interactive)
   (cond
    ((or (bolp) (not (looking-back "'")))
     ;; insert just one '
     (self-insert-command 1))
    ((save-excursion
       (backward-char)
       ;; Skip symbol backwards.
       (and (not (zerop (skip-syntax-backward "w_")))
	   (not (looking-back "`"))
	   (or (insert-and-inherit "`") t))))
    (t
     ;; insert `' around following symbol
     (delete-backward-char 1)
     (unless (looking-back "`") (insert-and-inherit "`"))
     (save-excursion
       (skip-syntax-forward "w_")
       (unless (looking-at "'") (insert-and-inherit "'"))))))

(global-set-key [39] 'insert-hyphen-or-two)

Thank you for this very useful function! It took me some time to understand how
to use  this function  ;-), because invoking it by M-x `insert-hyphen-or-two'
inserts 
 character

Sounds like you want insert-pair:
(define-key (current-global-map) "\M-'" 'insert-pair)
(define-key (current-global-map) "\C-c`" 'insert-pair)

Which makes M-' insert a pair of single quotes, and C-c ` insert `'.  
Then you can do M-1 M-' or M-1 C-c ` to enclose the sexp following  
point in the correct quotes.

insert-pair is super handy, I use M-(sym) for () "" [] etc.

Why is it called "insert-hyphen-or-two" when it inserts quotes, not 
hyphens?

Thanks for inspiration. I also found `skeleton-pair-insert-maybe'
function from skeleton library 

(setq skeleton-pair t)
(global-set-key "(" 'skeleton-pair-insert-maybe) % ()
(global-set-key "[" 'skeleton-pair-insert-maybe) % []
(global-set-key "{" 'skeleton-pair-insert-maybe) % ""
(global-set-key "\"" 'skeleton-pair-insert-maybe) % ''
(global-set-key "`" 'skeleton-pair-insert-maybe) % `'

This inserts pairs of chars and also enclose a region. Now I have at
least three solutions and will see with time what fits me better.

Sorry, I'll try to be less cryptic next time.  I use this function
because most often I first expand the name of the symbol and then
hitting "'" twice means I don't have to think about an extra command to
do what I want.  It doesn't work in c-mode because till now I was too
lazy to define a separate symbol-table for this.

I must have been drinking when I wrote that ;-)
