No module named 'readline'

Installed shakrespearelang and ran the example .spl and got the following error

Traceback (most recent call last): File "<frozen runpy>", line 198, in _run_module_as_main File "<frozen runpy>", line 88, in _run_code File "C:\Users\new\AppData\Local\Programs\Python\Python312\Scripts\shakespeare.exe\__main__.py", line 4, in <module> File "C:\Users\new\AppData\Local\Programs\Python\Python312\Lib\site-packages\shakespearelang\cli.py", line 7, in <module> from ._repl import start_console, debug_play File "C:\Users\new\AppData\Local\Programs\Python\Python312\Lib\site-packages\shakespearelang\_repl.py", line 6, in <module> import readline ModuleNotFoundError: No module named 'readline'

it seems that there is an import of an unused and missing module here

shakespearelang/shakespearelang/_repl.py

Line 6 in a4a2753

import readline

removing that import fixes it and the output is as expected

Hi @stuart-thomas-zoopla! Thanks for using shakespearelang!

It's actually not an unused import -- simply importing readline changes the behavior of input(). However, I did not realize when I wrote this that readline is only available on Unix-like systems. It doesn't work on Windows.

I'd be happy to accept a PR that wraps the import in a try block!

Ah ok, that makes sense. PR Incoming.

Immediate issue fixed by #21, though broader support for Windows is a bit unclear.
