Move the various map* functions to C; add #'map-into. src/ChangeLog addition: 2010-01-31 Aidan Kehoe <kehoea@parhasard.net> Move #'mapcar*, #'mapcan, #'mapc, #'map, #'mapl, #'mapcon to C; extend #'mapvector, #'mapconcat, #'mapcar to support more SEQUENCES; have them all error with circular lists. * fns.c (Fsubseq): Call CHECK_SEQUENCE here; Flength can return from the debugger if it errors with a non-sequence, leading to a crash in Fsubseq if sequence really is *not* a sequence. (mapcarX): Rename mapcar1 to mapcarX; rework it comprehensively to take an optional lisp output argument, and a varying number of sequences. Special-case a single list argument, as we used to, saving its elements in the stack space for the results before calling FUNCTION, so FUNCTION can corrupt the list all it wants. dead_wrong_type_argument() in the other cases if we encounter a non-cons where we expected a cons. (Fmapconcat): Accept further SEQUENCES after separator here. Special-case the idiom (mapconcat 'identity SEQUENCE), don't even funcall. (FmapcarX): Rename this from Fmapcar. Accept optional SEQUENCES. (Fmapvector): Accept optional SEQUENCES. (Fmapcan, Fmapc, Fmap): Move these here from cl-extra.el. (Fmap_into): New function, as specified by Common Lisp. (maplist): New function, the guts of the implementation of Fmaplist and Fmapl. (Fmaplist, Fmapl, Fmapcon): Move these from cl-extra.el. (syms_of_fns): Add a few needed symbols here, for the type tests used by #'map. Add the new subrs, with aliases for #'mapc-internal and #'mapcar. * general-slots.h: Declare Qcoerce here, now it's used in both indent.c and fns.c * indent.c (syms_of_indent): Qcoerce is gone from here. * lisp.h: Add ARRAYP(), SEQUENCEP(), and the corresponding CHECK_* macros. Declare Fbit_vector, Fstring, FmapcarX, now other files need to use them. * data.c (Farrayp, Fsequencep): Use ARRAYP and SEQUENCEP, just added to lisp.h * buffer.c (Fbuffer_list): Now Fmapcar has been renamed FmapcarX and takes MANY arguments, update this function to reflect that. lisp/ChangeLog addition: 2010-01-31 Aidan Kehoe <kehoea@parhasard.net> * cl.el (mapcar*): Delete; this is now in fns.c. Use #'mapc, not #'mapc-internal in a couple of places. * cl-macs.el (mapc, mapcar*, map): Delete these compiler macros now the corresponding functions are in fns.c; there's no run-time advantage to the macros. * cl-extra.el (coerce): Extend the possible conversions here a little; it's not remotely comprehensive yet, though it does allow running slightly more Common Lisp code than previously. (cl-mapcar-many): Delete. (map, maplist, mapc, mapl, mapcan, mapcon): Move these to fns.c. * bytecomp.el (byte-compile-maybe-mapc): Use #'mapc itself, not #'mapc-internal, now the former is in C. (mapcar*): Use #'byte-compile-maybe-mapc as this function's byte-compile method, now a #'mapc that can take more than one sequence is in C. * obsolete.el (cl-mapc): Move this compatibility alias to this file. * update-elc.el (do-autoload-commands): Use #'mapc, not #'mapc-internal here.

@appendix Standard Keymaps

The following symbols are used as the names for various keymaps.
Some of these exist when XEmacs is first started, others are
loaded only when their respective mode is used.  This is not
an exhaustive list.

Almost all of these maps are used as local maps.  Indeed, of the modes
that presently exist, only Vip mode and Terminal mode ever change the
global keymap.

@table @code
@item bookmark-map
@vindex bookmark-map
A keymap containing bindings to bookmark functions.

@item Buffer-menu-mode-map
@vindex Buffer-menu-mode-map
A keymap used by Buffer Menu mode.

@item c++-mode-map
@vindex c++-mode-map

@item help-map
@vindex help-map

cell.
