+;; USAGE =============================================================
+
+;; In C mode C-C C-e is bound to c-macro-expand. The result of the
+;; expansion is put in a separate buffer. A user option allows the
+;; window displaying the buffer to be optimally sized.
;;
;; When called with a C-u prefix, c-macro-expand replaces the selected
-;; region with the expansion. With two C-u's the user is offered to
-;; change the flags to the preprocessor (while the results of the
-;; expansion go to a separate buffer). Preprocessor arguments default
-;; to the last ones entered. Both the preprocessor name and the
-;; initial flag defaults can be set by the user. Setting
-;; c-macro-always-prompt to a non-nil value allows one to be always
-;; prompted for the flags, regardless of the prefix used.
+;; region with the expansion. Both the preprocessor name and the
+;; initial flag can be set by the user. If c-macro-prompt-flag is set
+;; to a non-nil value the user is offered to change the options to the
+;; preprocessor each time c-macro-expand is invoked. Preprocessor
+;; arguments default to the last ones entered. If c-macro-prompt-flag
+;; is nil, one must use M-x set-variable to set a different value for
+;; c-macro-cppflags.
;; A c-macro-expansion function is provided for non-interactive use.
-;; A still experimental function c-macro-eval is provided. It aims at
-;; evaluating the contents of a region by using calc (by Dave
-;; Gillespie). Select a region and type C-x C-e (if you followed the
-;; suggestions in the INSTALLATION section) or type M-x c-ma RET v
-;; RET. If you have calc installed, the computed value of the
-;; expression will appear in the message area. If you give an
-;; interactive C-u prefix the computed value will be shown in signed,
-;; unsigned, hex and boolean representations. Two C-u's allow to
-;; change the preprocessor flags via prompt. c-macro-eval works well
-;; for constant expressions, but see the BUG section.
-
-;; A patch to calc 2.02 has been written by Dave Gillespie. It can
-;; be downloaded via anonymous ftp at fly.cnuce.cnr.it:pub/calc.diff.
;; INSTALLATION ======================================================
-;; Put this file on your load-path, byte compile it for increased
-;; speed and put part or all of the following in your ~/.emacs file.
+;; Put the following in your ~/.emacs file.
-;; To make a directory ~/emacs be in front of your load-path:
-;;(setq load-path (cons (expand-file-name "~/emacs") load-path))
-;;
-;; Suggested keybindings (work only in c-mode):
-;;(define-key c-mode-map "\C-\M-x" 'c-macro-expand)
-;;(define-key c-mode-map "\C-x\C-e" 'c-macro-eval)
-;;
;; If you want the *Macroexpansion* window to be not higher than
-;; necessary:
-;;(setq c-macro-shrink-window-p t)
+;; necessary:
+;;(setq c-macro-shrink-window-flag t)
;;
;; If you use a preprocessor other than /lib/cpp (be careful to set a
;; -C option or equivalent in order to make the preprocessor not to
;; strip the comments):
;;(setq c-macro-preprocessor "gpp -C")
;;
-;; If you often use a particular set of flags, and want them to be
-;; the default:
-;;(setq c-macro-default-cppflags "-I /usr/include/local -DDEBUG"
-;;
-;; If you always want the "Preprocessor arguments: " prompt,
-;; regardless of the arguments provided:
-;;(setq c-macro-always-prompt-p t)
+;; If you often use a particular set of flags:
+;;(setq c-macro-cppflags "-I /usr/include/local -DDEBUG"

-;; "C constant expressions evaluation. Requires calc. Experimental." t)
+;; If you want the "Preprocessor arguments: " prompt:

;; BUG REPORTS =======================================================
;; Please report bugs, suggestions, complaints and so on to
-;; pot@cnuce.cnr.it (Francesco Potorti`).
+;; pot@gnu.org (Francesco Potorti`).
;; IMPROVEMENTS OVER emacs 18.xx cmacexp.el ==========================
-;; - A lot of user visible changes. See above.
+;; - A lot of user and programmer visible changes. See above.
;; - #line directives are inserted, so __LINE__ and __FILE__ are
;; correctly expanded. Works even with START inside a string, a
;; comment or a region #ifdef'd away by cpp. cpp is invoked with -C,
;; making comments visible in the expansion.
;; - All work is done in core memory, no need for temporary files.
-;; - The /lib/cpp process is run synchronously. This fixes an
-;; infinite loop bug on Motorola Delta (cpp waiting forever for
-;; end-of-file, don't know why). Fixes a similar intermittent
-;; problem on SunOS 4.1.
;; ACKNOWLEDGEMENTS ==================================================
;; A lot of thanks to Don Maszle who did a great work of testing, bug
-;; reporting and suggestion of new features and to Dave Gillespie for
-;; his suggestions about calc. This work has been partially inspired by
-;; Don Maszle and Jonathan Segal's.
+;; reporting and suggestion of new features. This work has been
+;; partially inspired by Don Maszle and Jonathan Segal's.
;; BUGS ==============================================================
-;; calc 2.02 does not handle the C operators "->", ".", "*" (as a
-;; prefix), the composite assignement operators "+=" etc. It cannot
-;; handle the "," operator and will be confused by ";". Almost all
-;; these can be defined as no-ops using the Calc's Syntax Tables
-;; feature. The built-in calc functions will cause problems in
-;; certain circumstances. c-macro-eval behaves correctly only on
-;; expressions not containing such operators. Does not distinguish
-;; among integer and real division.
-
;; If the start point of the region is inside a macro definition the
;; macro expansion is often inaccurate.
