annotate lisp/update-elc.el @ 5067:7d7ae8db0341
add functions `stable-union' and `stable-intersection' to do stable set operations
-------------------- ChangeLog entries follow: --------------------
lisp/ChangeLog addition:
2010-02-22 Ben Wing <ben@xemacs.org>
* cl-seq.el:
* cl-seq.el (stable-union): New.
* cl-seq.el (stable-intersection): New.
New functions to do stable set operations, i.e. preserve the order
of the elements in the argument lists, and prefer LIST1 over LIST2
when ordering the combined result. The result looks as much like
LIST1 as possible, followed (in the case of `stable-union') by
any necessary elements from LIST2, in order. This is contrary to
`union' and `intersection', which are not required to be order-
preserving and are not -- they prefer LIST2 and output results in
backwards order.

33 ;; Byte compile the .EL files necessary to dump out xemacs. | |
1261 | 34 ;; Also update the auto-autoloads.el files. |
35 | |
428 | 36 ;; Use this file like this: |
37 | |
38 ;; temacs -batch -l ../lisp/update-elc.el $lisp | |
39 | |
40 ;; where $lisp comes from the Makefile. .elc files listed in $lisp will | |
41 ;; cause the corresponding .el file to be compiled. .el files listed in | |
42 ;; $lisp will be ignored. | |
43 | |
44 ;; (the idea here is that you can bootstrap if your .ELC files | |
45 ;; are missing or badly out-of-date) | |
