Function: cl-old-struct-compat-mode

cl-old-struct-compat-mode is an autoloaded, interactive and byte-compiled function defined in cl-lib.el.gz.

Signature

(cl-old-struct-compat-mode &optional ARG)

Documentation

Enable backward compatibility with old-style structs.

This can be needed when using code byte-compiled using the old macro-expansion of cl-defstruct that used vectors objects instead of record objects.

This is a global minor mode. If called interactively, toggle the Cl-Old-Struct-Compat mode mode. If the prefix argument is positive, enable the mode, and if it is zero or negative, disable the mode.

If called from Lisp, toggle the mode if ARG is toggle. Enable the mode if ARG is nil, omitted, or is a positive number. Disable the mode if ARG is a negative number.

To check whether the minor mode is enabled in the current buffer, evaluate (default-value \=cl-old-struct-compat-mode)'.

The mode's hook is called both when the mode is enabled and when it is disabled.
