Subject: let-alist can't deal with the keys which includes spaces.
Date: Tue, 20 Jul 2021 19:12:14 +0800 [thread overview]
Message-ID: <CAGP6POJjbMkiqy4RgBwQHAGJjjKzJ0_25FtcLANMjA4cubYw7A@mail.gmail.com> (raw)
I adapted the examples given on
<https://www.gnu.org/software/emacs/manual/html_node/elisp/Association-Lists.html>
to the following:
;;;
(setq colors '(("rose merry" . red) (lily (belladonna . yellow))))
(let-alist colors
(if (eq ."rose merry" 'red)
.lily.belladonna))
;;;
When I try to evaluate the above code snippet, the following error is triggered:
Debugger entered--Lisp error: (invalid-read-syntax ". in wrong context" 8 28)
read(#<buffer *scratch*>)
elisp--preceding-sexp()
elisp--eval-last-sexp(t)
eval-last-sexp(t)
eval-print-last-sexp(nil)
funcall-interactively(eval-print-last-sexp nil)
call-interactively(eval-print-last-sexp nil nil)
command-execute(eval-print-last-sexp)
It seems that let-alist can't deal with the keys which includes
spaces. Any hints for this problem will be highly appreciated.
Regards
