Hi,
this is the problem:
- emacs -Q
- Evaluate: (cl-letf (((default-value 'process-environment) nil)))
- You see the following error:
Debugger entered--Lisp error: (void-function cl-letf)
(cl-letf (((default-value 'process-environment) nil)))
(progn (cl-letf (((default-value 'process-environment) nil))))
eval((progn (cl-letf (((default-value 'process-environment) nil)))) t)
elisp--eval-last-sexp(nil)
eval-last-sexp(nil)
funcall-interactively(eval-last-sexp nil)
call-interactively(eval-last-sexp nil nil)
command-execute(eval-last-sexp)
- Evaluate again: (cl-letf (((default-value 'process-environment) nil)))
The error is not shown any more.
For reference, I discovered this while using buffer-env:
https://github.com/astoff/buffer-env/issues/15.
Augusto Stoffel provided the small recipe, I was seeing the message
"‘((default-value 'process-environment) process-environment)’ is a
malformed function" as I wrote in the above mentioned ticket.
