Numparam and Noop
|
This effect caused me to make a workaround in the past but I didn't realize what was going on. Could anyone explain this please?
What I had liked about this was I could use params without trimming
#var PRH_GvvOrders ""
#loop %numparam( ) {#var PRH_GvvOrders %additem( %param( %i), @PRH_GvvOrders)}
#noop
@PRH_GvvOrders = "do|re|me|fa|so|la|te" now
_________ With Showing the Stringlist
#var PRH_GvvOrders ""
#loop %numparam( ) {#var PRH_GvvOrders %additem( %param( %i), @PRH_GvvOrders)}
#noop
#forall @PRH_GvvOrders {
#sh %i
}
Prints that stringlist with what looks like %-1 after %i:
do do re me fa so la te
re do re me fa so la te
me do re me fa so la te
fa do re me fa so la te
so do re me fa so la te
la do re me fa so la te
te do re me fa so la te
_________ adding an odd #NOOP to the #FORALL
#var PRH_GvvOrders ""
#loop %numparam( ) {#var PRH_GvvOrders %additem( %param( %i), @PRH_GvvOrders)}
#noop
#forall @PRH_GvvOrders {
#sh %i
#noop
}
Prints correctly:
do
re
me
fa
so
la
te |

That is rather odd. Aliases are supposed to auto append unused parameters to the end. It is wierd that that append would produce that output. Use this method to mark all the parameters as used instead.
| Code: |
#noop %-1
#var PRH_GvvOrders ""
#loop %numparam( ) {#var PRH_GvvOrders %additem( %param( %i), @PRH_GvvOrders)}
#forall @PRH_GvvOrders {
#sh %i
} |

Thanks for that. 
I think this is a faster and more predictible way of replacing spaces but once while trying to use the regex "\p" in %subregex, I caused ZMud to crash
| Code: |
| %subregex("d x z z","\s+","|") |
returns; d|x|z|z
so I am wary of pipes, I will try it though unless anyone thinks it is a bad idea.
Thanks again |
