JsonToMath_Generator

Math Problem Generation, via RNG number set generation, from range and condition/s, and Math Expression Engine (inspired by Brad Robinson's SimpleExpressionEngine).
Intended to be used with external service, providing sets of objects, including all necessary data to generate a math problem set in string arrays.
Written and used with C# compiler.

Usage

• Import source code:
  • GeneratorParser:
    • GeneratorParser.Parse(string[], Random) - Generate numbers, 1 per set. Pass a Random as source of RNG.
    • GeneratorParser.BuildSet(string, List<double>, bool) - Replace tokens in string, from passed set of numbers. Optional: ignore strings starting with {}
  • ParserNode:
    • ParserNode.Parse(string) - Returns result of a math expression, passed as a string.

Syntax

• Range:

  • Valid: "0:99"
  • Invalid: "0:-99" - supposed max range is less than the minimal range

• Conditions:

  • Modulo:
    • Valid:
      • "0:99%(2)" - 0-99 number, which has modulo 2 equal to 0
      • "0:99%({0})==2" - 0-99 number, which has modulo of the previous generated number equal to 2
      • "0:99%(4&&{0}||9)==2" - 0-99 number, which has modulo of 4 and the previous generated number, or only 9, equal to 2
    • Invalid:
      • "0:99%1" - missing ()
      • "0:99%{0}" - missing ()
      • "0:99%({0}==2)" - invalid == placement
  • Less, LessOrEqual, Greater, GreaterOrEqual:
    • Valid:
      • "0:99>(2)" - 0-99 number, which is greater than 2
      • "0:99<(2)" - 0-99 number, which is less than 2
      • "0:99>=({0})" - 0-99 number, which is greater than or equal to the first generated number
      • "0:99<=({0}&&4||9)" - 0-99 number, which is less than or equal to the first generated number and 4, or only 9
    • Invalid:
      • "0:99<=1" - missing ()
      • "0:99<=(0:99)" - cannot generate number while already generating number. Too random
      • "0:99>=(0)&&<=(99)" - not yet implemented syntax.
