| 30 ;;; Commentary: | |
| 31 ;; | |
| 32 ;; This file implements the code to create and edit customize buffers. | |
| 33 ;; | |
| 34 ;; See `custom.el'. | |
| 35 | |
| 36 ;; No commands should have names starting with `custom-' because | |
| 37 ;; that interferes with completion. Use `customize-' for commands | |
| 38 ;; that the user will run with M-x, and `Custom-' for interactive commands. | |
| 39 | |
| 40 ;; NOTE: In many places within this file we use `mapatoms', which is | |
| 41 ;; very slow in an average XEmacs because of the large number of | |
| 42 ;; symbols requiring a large number of funcalls -- XEmacs with Gnus | |
| 43 ;; can grow to some 17000 symbols without ever doing anything fancy. | |
| 44 ;; It would probably pay off to make a hash table of symbols known to | |
| 45 ;; Custom, similar to custom-group-hash-table. | |
| 46 | |
| 47 ;; This is not top priority, because none of the functions that do | |
| 48 ;; mapatoms are speed-critical (the one that was now uses | |
| 49 ;; custom-group-hash-table), but it would be nice to have. | |
