How do I break one property into two?

[Zaran]

I'm working on some Heavy Gear macros and I'd like to take a property that's in this form: "xD+n" and turn it into two new properties "x" and "n"

How do I do this? (the D will always be in the property)

So, what are the possible combinations:
xD
xD+n
xD-n

??

your a bit vague, but if i take it literally and assuming that x and n are always single characters then you can use Wiki: substring():

Code: Select all

[prop="xD+n"]
[x = substring(prop, 0,1)]
[n = substring(prop, 3)]

if they're not, then you'll probly need regex to retrieve them. bit trickier and you'll need: Wiki: getGroup()

I think this is exactly what I need. Thanks.

That will work is x and n is a single digit.

Since you didn't answer my questions I'm going to assume the format will always be xD+n. I suggest doing this:

Code: Select all

[H: prop="xD+n"]
[H: x = listGet(prop,0,"D")] <!-- everything before "D" -->
[H: n = listGet(prop,1,"+")] <!-- everything after "+" -->

But if I were to do this the "right" way, I would use regex.

I'd personally use listGet's list separator in this situation... Just for the sake of multiple opinions.

[code][h: diceString = "1d5"]
[r: diceQuantity = listGet(diceList,0,"d")]
[r: diceSides = listGet(diceList,1,"d")][/code]

Results in:
1
5

edited to remove the wasteful stringToList and just use listGet

These are the possible combinations yes.

These are the possible combinations yes.

in that case youll need to check the string Wiki: length ()cause the second substring command will render an error in case of xD

I can work around that by just making it xD+0 .

The whole problem is routed around mechanics of the Silhouette system. 2d+1 doesn't do 3-13 as a result in that game. It takes the highest of the dice rolled and adds 1 for every extra 6 rolled. So i'll need to be able to break down how one records each skill roll into the two parts so that it can roll the dice and then add the mod.

I think this should cover most instances including bad input.

Code: Select all

[H: abort(input("strInput|0|Enter dice string. Format xD[+/-n]"))]
<!-- 
   (?i) = case insensitive; 
   ([0-9]+) = 1 or more digits (group 1); 
   D(.*) = D followed by anything, anything is (group2) 
-->
[H: regex = "(?i)([0-9]+)D(.*)"]
[H: findId = strfind(strInput,regex)]
[H: foundMatch = getFindCount(findId)]

[H, if(foundMatch), code: {
   <!-- x is the first match of group 1 -->
   [H: x = getGroup(findId,1,1)]
   <!-- n is the first match of group 2 -->
   [H: n = getGroup(findId,1,2)]
   <!-- clean up n. Save only digits and +,- symbols. -->
   [H, if(length(n)): n = replace(n,"[^0-9+-]","")]
   <!-- set n to 0 if not a number (like a blank) -->
   [H, if(! isNumber(n)): n = 0]
};{
   [H: x = ""]
   [H: n = ""]
}]
[R, if(foundMatch): strformat("Input: %{strInput}; x = %{x}; n = %{n}"); 
      strformat("No matches found: '%{strInput}'")]
