A powerful and easy expression language for use in Java desktop and web applications. Example of string parsing: "Hallo Mr. {:name}, {:vname}. This is your number: {%mathMax {'0.3'},{'0.4'},{%mathRandom}, {'0.5'}}"

Features

  • supports multiple evaluation contexts
  • easy to use: you only submit a code string and you get the result
  • easly define new functions and load them with properties files
  • user-defined functions {%functionXYZ {param1}, {param2}, ...}
  • variables per context: {:var1}
  • system variables: {@sysvar1}
  • dynamic function or variable resolving: {>{':'}{:myvarname}}
  • expressions: {= ({2} + {4}) * ({1.5}-{5}) }
  • validation: {%mathRandom} < {10} * ({:z1} + {:z2} + {1})
  • type safety and type casting: {(N)'3.5'} casts string 3.5 to number
  • boolean operators: and, or, !=, =, > ,<, >=, <=
  • building groups with "{" and "}"
