support python typing in pre/post script when using analyzeHeadless

[axel7083]

Is your feature request related to a problem? Please describe.

I am using the analyzeHeadless, and provide a python script through the -postScript, however when trying to annotate my code with argument type, and return type for function it will raise an error.

Here is an example of a function I created

from typing import Optional

# ghidra imports
import ghidra.program.database.function.FunctionDB

# Note that multiple functions can share the same name, so this
# function will only return the first one
def find_function_by_name(name: str) -> Optional[FunctionDB]:
    funcs = getGlobalFunctions(name)
    print("Found {} function(s) with the name '{}'".format(len(funcs), name))
    if len(funcs) > 0:
        return funcs[0]
    return None

But once running I am getting the following error

INFO  SCRIPT: C:\Users\....\scripts\ghidra.py (HeadlessAnalyzer)  
  File "C:\Users\axels\OneDrive\Bureau\SM64DS\sm64-unpack\scripts\ghidra.py", line 8
    def find_function_by_name(name: str) -> Optional[FunctionDB]:
                                 ^
SyntaxError: mismatched input ':' expecting RPAREN

Describe the solution you'd like

Hopefully a support for running script containing python typing.

Describe alternatives you've considered

Remove the typing makes everything works.

Are you just using Ghidra's built-in Jython support (which only supports Python 2), or are you using a 3rd party extension like Pyhidra or Ghidrathon? Typing is not supported in Python 2.

You are right, when using it, I thought I was using some kind of python 3 version, but apparently Jython 2. Closing as cannot be solved
