Interpreter

Developers

To interpret your code, at first you need to create an abstract syntax tree by using Interpreter.textToAST <string>. Then you can run the Interpreter.run <AST> to execute your program.

Another functions

  • processExpr (vDict: Dictionary<AST.VName, VType>) (expression: AST.Expr) - return a result of a given expression in VType format.
  • processStmt (vDict: Dictionary<AST.VName, VType>) (stmt: AST.Stmt) - gets an expression from statement and sets it's value to the dictionary with variable as a key.

Example

let program = "

let [x] = (a|b)caba
let [c] = isAcceptable \"acaba\" [x]
let [d] = isAcceptable \"1\" (1*)&(1?)
let [e] = findAll \"muxa\" (x|a)

print [c]
print [d]
print [e]"

let ast = Interpreter.parseProgramToAST program
Interpreter.run ast

Given code prints 

True
True
[(2, 3);(3, 4)]
into console.
