问题
Is there a way to copy/yank a whole a form in Slime/Emacs?
For instance, if I have the following function:
(myfunc (lst)
(myotherfunc lst))
I'd like to yank/copy:
(myotherfunc lst)
by issuing a keyboard shortcut when my cursor is at the opening or closing parenthesis for that form (at the point where Slime/Emacs does parenthesis matching).
回答1:
In my Emacs, function kill-sexp is bound to C-M-k. That is, assuming the point is just before an opening delimiter of a balanced expression, press Control, Meta, and k at the same time.
This same command works in various other non-Lisp modes, such as killing brace-delimited blocks in a C-style mode, though the kill-sexp command may not be bound to the same keys.
回答2:
C-M-SPC (mark-sexp) to put the mark at the end of the sexp, then copy/yank
C-M-f (forward-sexp) and C-M-b (backward-sexp) are useful to move forward and backward over a balanced expression

The emacs minor mode ParEdit does this on normal kills 'C-k' by default. I would certainly recommend it to any emacs+slime users.

You can use lispy and then you can press n which runs lispy-new-copy to copy
(myotherfunc lst)
