a library for the Myte playground that allows you to reduce RPN expressions from within tuples

reduce.nv Sin formato Playground
1| 'DOCUMENTATION' | ~~
2 the @reduce library allows you to reduce RPN expressions
3 that are enclosed within curly braces inside of a tuple .
4 here's an example of how to use it :
5
6 '' (@reduce snake = x is { 2 3 + 4 * } and y is { 10 7 - } .)
7
8 this will result in the following :
9
10 'snake' x is 20 and y is 3
11
12 also note that you can replace the stack name with @main to
13 push the result to the main stack .

16| '' (@reduce .) | '' convert output stack to tuple
17| '' @reduce? '' ($stack =) | 'destination' $stack
18| '' @reduce? '' ({ }) 'numbers' $result | 'output' $result
19
20| '' @reduce? '' {? '' + 'numbers' ($b $a) | '@js' f("numbers", "" + (Number($a) + Number($b)));
21| '' @reduce? '' {? '' - 'numbers' ($b $a) | '@js' f("numbers", "" + (Number($a) - Number($b)));
22| '' @reduce? '' {? '' * 'numbers' ($b $a) | '@js' f("numbers", "" + (Number($a) * Number($b)));
23| '' @reduce? '' {? '' / 'numbers' ($b $a) | '@js' f("numbers", "" + (Number($a) / Number($b)));
24
25| '' @reduce? '' {? '' random 'numbers' ($max $min) | '@js'
26 const min = Number($min), max = Number($max);
27 f("numbers", min + Math.floor(Math.random() * (max - min)));
28
29| '' @reduce? '' {? '' wrap 'numbers' ($max $min $a) | '@js'
30 const a = Number($a), min = Number($min), max = Number($max);
31 let result = a;
32 if (a < min) result = max;
33 if (a > max) result = min;
34 f("numbers", result);
35
36| '' @reduce? '' {? '' $number| 'numbers' $number
37| '' @reduce? '' $word | 'output' $word
