Function definition of a void function: incf (generic lisp function in emacs24)

Question

I downloaded the emacs package to format python codes with autopep8.

This package is called py-autopep8

this is lisp code

can you specify line number 78 of this generic lisp function

(incf line-offset len)

then when I open emacs24 and I want to save the buffer, I have this in the emacs shell

Character Definition Function void: incf

Does anyone know how to fix this error, therefore, to get general lisp definitions in emacs lips.

Answer 1

The standard common Lisp functions are implemented in the package cl, so you can put:

(require 'cl)

in the initialization file.

, cl-incf cl-lib cl incf cl-incf.

cl-lib cl-incf; cl-lib , .
