rb-mymath

Mathmatical parser and executer, with a AST visualizer

Notes

MyMath_AST

each function is a tree
there is a variable table

main execution is also a tree but the main default one

Statements:  BlockNode(n)  AssignNode(name, 1)  ReturnNode(1)

Expressions: BinaryNode(op, 2)  UnaryNode(op, 1)  IfNode(3)
             CallNode(name, n)  LambdaNode(params, body=BlockNode)

Leaves:      NumNode(float64)  VarNode(name)

Runtime values: Number | Function{params, body, scope}
Scope: {vars map, parent *Scope}



Leaves:      
    NumNode(float64) 
    # integerLiteral
    # decimalLiteral
    # scientificLiteral

    VarNode(name)
    # variable

Expressions: 
    BinaryNode(op, 2)  
    # mulDivModExpr
    # implicitMulExpr
    # addSubExpr
    # comparisonExpr
    # equalityExpr
    # andExpr
    # xorExpr
    # orExpr
    # powerExpr

    UnaryNode(op, 1)  
    # unaryExpr
    # notExpr
    # signedExponent
    # parenExpr

    IfNode(3)         
    # ifExpr


    
    # assignment

    CallNode(name, n)  
    # functionCall

    LambdaNode(params, body=BlockNode)
    # block
    # returnStatement
    # blockLambda
    # arrowLambda
