; Deprecated and should not be used in new scripts.
; GIMP developers strongly recommend you not use this file
; in scripts that you will distribute to other users.
; Mostly definitions from the ancient SIOD dialect of Scheme.
; These were deprecated in GIMP 2 and obsoleted in GIMP 3
; ScriptFu since v3 does not automatically load these definitions.
; This file is NOT automatically loaded by ScriptFu.
; A script can load this file at runtime like this:
;
; (define my-plug-in-run-func
; (load (string-append
; script-fu-sys-init-directory
; DIR-SEPARATOR
; "SIOD-compat.scm"))
; ...
; )
;
; Note this puts the definitions in execution-scope, not global scope.
; They will affect all functions called.
; They can affect ScriptFu plugin scripts called.
; They will go out of scope when the run-func completes.
; *pi*, butlast, and cons-array symbols were deprecated in v2.
; They remain in v3, still deprecated.
; See also the companion file PDB-compat-v2.scm
; which defines aliases for obsolete PDB procedure names, from GIMP 2.
