用Python和pyparsing解析Visual Basic函数的参数列表

from pyparsing import Word, Literal, delimitedList, Optional, Group

# 定义语法规则
identifier = Word(alphas, alphanums + "_")
dataType = Word(alphas)
parameter = Group(identifier + Optional(Literal("As") + dataType))
parameters = delimitedList(parameter)

# 定义要解析的文本
text = "Function myFunction(param1 As Integer, param2 As String) As Boolean"

# 解析参数列表
result = parameters.parseString(text)

# 打印解析结果
for param in result:
    print("Parameter name:", param[0])
    print("Parameter type:", param[1])
    print()
