How do I break one property into two?

Post by 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 [wfunc]substring[/wfunc]:

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: [wfunc]getGroup[/wfunc]

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: Select all

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


Results in:
1
5

edited to remove the wasteful stringToList and just use listGet

These are the possible combinations yes.

in that case youll need to check the string [wfunc]length [/wfunc]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}'")]
