Zillions has a "positions" and a "kill-positions" command, it has a "links" command,
but no "kill-links" command.
I STRONGLY suggest to include this in the next Zillions release.
Example (chess):
(kill-links e (b3 c3) (c3 d3))
In grids with many links it makes no sense
to code all the links by hand,
simulating what a grid statement followed by a kill-links command would do.

unlink
(unlink ...)
unlink accepts a list of any number of arguments , where each argument is in one of the following 3 forms:
Deletes all links (if any) going into and out of that position
( ) Deletes all links (if any) directly connecting the positions
( ) Deletes the link in the given direction from the position, if it exists
Examples:
(unlink e4 d7 c6) ; Removes all links to/from positions e4, d7, c6
(unlink (a1 b1) ) ; Removes all links connecting a1 to b1
(unlink (a1 b1) (a8 b8)) ; Disconnects a1 and b1, Disconnects a8 and b8
; Removes the “n” link coming out of position a1
; Note: this has no effect on any links coming into a1.
(unlink (a1 n))
; The different types may all appear on the same list
(unlink e4 (a1 a2) d7 (a1 ne))
Usage:
(game
...
(board
...
(unlink a b (c d) e f)
...
)
...
)

Yes, of course.
I had forgotten about unlink.
That case nicely shows what a lack of standards in naming conventions can do.
If the opposite of "positions"
is "kill-positions", then the opposite
of "links" of course should be "kill-links".
(I have worked for many years as a software engineer, especially pushing better and more
userfriendly software standards.
One cannot emphasize their importance enough..)

Of course unlinks may have been implemented first -- then when need for a kill-positions command came along, achieving a standard by naming it "unposition" doesn't really seem worth it... Sorry for the confusion. |
