Add command remapping, a more robust alternative to #'substitute-key-definition src/ChangeLog addition: 2012-09-02 Aidan Kehoe <kehoea@parhasard.net> * keymap.c: Add command remapping, a more robust equivalent to #'substitute-key-definition. * keymap.c (CHECK_REMAPPING_POSITION): New. * keymap.c (keymap_equal): Correct a comment here. * keymap.c (Fdefine_key): Document the command remapping syntax. * keymap.c (Fremap_command): New. * keymap.c (command_remapping): New. * keymap.c (Fcommand_remapping): New. * keymap.c (commands_remapped_to_mapper): New. * keymap.c (commands_remapped_to_traverser): New. * keymap.c (Fcommands_remapped_to): New. * keymap.c (get_relevant_keymaps): Take a new POSITION argument. * keymap.c (Fcurrent_keymaps, event_binding): Supply the new POSITION argument to get_relevant_keymaps. * keymap.c (Fkey_binding): Add new arguments, NO-REMAP and POSITION. * keymap.c (map_keymap_mapper): * keymap.c (Fwhere_is_internal): * keymap.c (where_is_to_char): * keymap.c (where_is_recursive_mapper): Don't expose the key remapping in these functions. This conflicts with GNU, but is more sane for our callers. Access to command remapping is with the functions #'command-remapping, #'commands-remapped-to, and #'remap-command, not with the general keymap functions, apart from the compatibility hack in #'define-key. * keymap.c (syms_of_keymap): * keymap.c (vars_of_keymap): * keymap.c (complex_vars_of_keymap): * lisp.h: New CHECK_COMMAND macro. man/ChangeLog addition: 2012-09-02 Aidan Kehoe <kehoea@parhasard.net> * lispref/keymaps.texi (Keymaps): * lispref/keymaps.texi (Changing Key Bindings): * lispref/keymaps.texi (Scanning Keymaps): * lispref/keymaps.texi (Remapping commands): * lispref/keymaps.texi (XEmacs): New. * lispref/keymaps.texi (Other Keymap Functions): Document the new command remapping functionality in this file. lisp/ChangeLog addition: 2012-09-02 Aidan Kehoe <kehoea@parhasard.net> * help.el (describe-function-1): Document any command remapping that has been done in this function. tests/ChangeLog addition: 2012-09-02 Aidan Kehoe <kehoea@parhasard.net> * automated/keymap-tests.el: Test the new command remapping functionality.
