30 ;; This file implements the code to create and edit customize buffers.
|
|
|
31 ;;
|
|
|
32 ;; See `custom.el'.
|
|
|
33
|
|
|
34 ;; No commands should have names starting with `custom-' because
|
|
|
35 ;; that interferes with completion. Use `customize-' for commands
|
|
|
36 ;; that the user will run with M-x, and `Custom-' for interactive commands.
|
|
|
37
|
|
223
|
38 ;; NOTE: In many places within this file we use `mapatoms', which is
|
|
|
39 ;; very slow in an average XEmacs because of the large number of
|
|
|
40 ;; symbols requiring a large number of funcalls -- XEmacs with Gnus
|
|
|
41 ;; can grow to some 17000 symbols without ever doing anything fancy.
|
|
380
|
42 ;; It would probably pay off to make a hash table of symbols known to
|
|
223
|
43 ;; Custom, similar to custom-group-hash-table.
|
|
|
44
|
|
|
45 ;; This is not top priority, because none of the functions that do
|
|
|
46 ;; mapatoms are speed-critical (the one that was now uses
|
|
|
47 ;; custom-group-hash-table), but it would be nice to have.
