Is there a concise emacs lisp equivalent of Python's [n:m] list slices?
elisp, emacs, python
Solution
Sure there is:
(require 'cl-lib)
(setq mylist '("foo" "bar" "baz" "qux" "frobnitz"))
(cl-subseq mylist 1 4)
;; ("bar" "baz" "qux")
In modern Emacs, please note `cl` is deprecated see In Emacs, what does this error mean? "Warning: cl package required at runtime"
Problem
One thing I find myself missing in emacs lisp is, surprisingly, a particular bit of list manipulation. I miss Python's concise list slicing. ``` >>> mylist = ["foo", "bar", "baz", "qux", "frobnitz"] >>> mylist[1:4] ['bar', 'baz', 'qux'] ``` I see the functions `butlast` and `nthcdr` in the emacs documentation, which would give the same results from code like this: ``` (setq mylist '("foo" "bar" "baz" "qux" "frobnitz")) (butlast (nthcdr 1 mylist) 1) ;; ("bar" "baz" "qux") ``` Is there a more concise way of getting a list slice than combining `butlast` and `nthcdr`?
