Numerical Sorting...
|
Ok...
Say you have this variable:
| Code: |
| #VAR Blah {10000000|500000|10000|250|5000|250000|1000000|5000000|10|50|1000|50000|1|2000|500|4000000|4000|2000000|100|7500000} |
And you want to sort it to be properly listed in numerical significance... does zMUD have a way to do this natively, and DON'T say the %sort, since that returns this:
| Code: |
| 1 10 100 1000 10000 1000000 10000000 2000 2000000 250 250000 4000 4000000 50 500 5000 50000 500000 5000000 7500000 |
Now I know I could do it with a simple little bit of code...
| Code: |
#while (%numitems(@Blah)) {
#var temp %item(@Blah,1)
#loop %numitems(@Blah) {
#IF (%int(%item(@Blah,%i)) < %int(@temp)) {#var temp %item(@Blah,%i)}
}
#ADDITEM Display @temp
#DELITEM Blah @temp
}
|
But Shouldn't zMUD have such a command?
Anyways, As far as I know zMUD does NOT have such a command, so this is mostly a contrived example to show others how it could be done. I'm posting in the CMUD Beta forum to suggest such a command.
[edit]
Forgot to add the %int() around the vars in the if statement, it always comes up false without them...

zMUD is feature complete now and won't be developed further. CMUD could potentially include this, though.

You could always pad the numbers to a fixed length when building the list.
| Code: |
Blech = ""
#forall @Blah {#additem Blech %rightback( %concat( " ", %i), 9)}
#show %sort(@Blech)
|
Ideally you'd be doing the padding when you built the list though, so it wouldn't be as artificial and wasteful as this example. |

Good idea, though I'd use zeros rather than spaces, and check that the string is a number first.

Zeroes would be useful in some situations but spaces are easier to trim back off later and look neater to the human eye. The sort doesn't care; space comes before all digits (and indeed everything else printable) in ASCII.

Its quicker and more efficient for me to just run it through my own sorter, and yes I know zMUD is *complete* hence saying it was for others' reference only and that I was suggesting it for CMUD *whaps you all*

I took this to mean "But shouldn't this command be added to zMUD?". Apologies if that isn't what you meant. |

Nah mate, no apologies are necessary... it was a rhetorical question :)

This is I think a faster way to sort numerically.
Ascending
#var sortedlist %replace(%mss(%concat("[",%expandlist(@slist,","),"]",".sort(function(A,B){return (Number(A)<Number(B))? -1:(Number(A)==Number(B))?0:1})"),"JScript"),",","|")
Descending
#var sortedlist %replace(%mss(%concat("[",%expandlist(@slist,","),"]",".sort(function(A,B){return (Number(A)>Number(B))? -1:(Number(A)==Number(B))?0:1})"),"JScript"),",","|") |
