;;; Commentary:
;; The Compat package on ELPA provides forward-compatibility
;; definitions for other packages. While mostly transparent, a
;; minimal API is necessary whenever core definitions change calling
;; conventions (e.g. `plist-get' can be invoked with a predicate from
;; Emacs 29.1 onward). For core packages on ELPA to be able to take
;; advantage of this functionality, the macros `compat-function' and
;; `compat-call' have to be available in the core, usable even if
;; users do not have the Compat package installed, which this file
;; ensures.
;; Note that Compat is not a core package and this file is not
;; available on GNU ELPA.
;;; Code:
(defmacro compat-function (fun)
"Return compatibility function symbol for FUN.
This is a pseudo-compatibility stub for core packages on ELPA,
that depend on the Compat package, whenever the user doesn't have
the package installed on their current system."
`#',fun)
(defmacro compat-call (fun &rest args)
"Call compatibility function or macro FUN with ARGS.
This is a pseudo-compatibility stub for core packages on ELPA,
that depend on the Compat package, whenever the user doesn't have
the package installed on their current system."
(cons fun args))
(provide 'compat)
