Parsing 使用OperatorReceidenceParser使用FParsec解析函数应用程序？

问题类似于，但我想使用

FParsec

中的

operatorreceidenceparser

解析一个带有函数应用程序的表达式

这是我的简历：

type Expression =
  | Float of float
  | Variable of VarIdentifier
  | BinaryOperation of Operator * Expression * Expression
  | FunctionCall of VarIdentifier (*fun name*) * Expression list (*arguments*)

我有以下意见：

board→create_obstacle(4, 4, 450, 0, fric)

下面是解析器代码：

let expr = (number |>> Float) <|> (ident |>> Variable)
let parenexpr = between (str_ws "(") (str_ws ")") expr

let opp = new OperatorPrecedenceParser<_,_,_>()

opp.TermParser <- expr <|> parenexpr

opp.AddOperator(InfixOperator("→", ws, 
  10, Associativity.Right, 
  fun left right -> BinaryOperation(Arrow, left, right)))

我的解析器当前有以下输出：

Success: Expression (BinaryOperation 
     (Arrow,Variable "board",Variable "create_obstacle"))

我想要的是得到以下信息：

 Success: Expression 
      (BinaryOperation 
            (Arrow,
                Variable "board",
                Function (VarIdentifier "create_obstacle",
                          [Float 4, Float 4, Float 450, Float 0, Variable "fric"]))

您可以将参数列表解析为标识符的可选后缀表达式

let argListInParens = between (str_ws "(") (str_ws ")") argList
let identWithOptArgs = 
    pipe2 ident (opt argListInParens) 
          (fun id optArgs -> match optArgs with
                             | Some args -> FunctionCall(id, args)
                             | None -> Variable(id))

然后定义

expr

like

let expr = (number |>> Float) <|> identWithOptArgs

let expr=（数字|>>Float）identWithOptArgs

let expr = (number |>> Float) <|> identWithOptArgs
