Keys are interpreted incorrectly on Linux

[GeorgeCiesinski]

Description

Depending on if the program is ran on Windows or Linux, the key codes are interpreted differently. This results in the numpad keys and some letter keys being interpreted incorrectly. Further inspection revealed that the virtual key codes appear to be about 32 apart from each other for the letter keys, and different amounts apart in other types of keys (!! is only 16 apart). Numpad keys don't register virtual key codes.

Example of the behavior when typing !reload:

Type	Linux	Windows
Read as:	Key.shift	Key.shift
Virtual Key:	33	49
Read as:	!	!
Virtual Key:	114	82
Read as:	r	r
Virtual Key:	101	69
Read as:	5	e
Virtual Key:	108	76
Read as:	l	l
Virtual Key:	111	79
Read as:	o	o
Virtual Key:	97	65
Read as:	1	a
Virtual Key:	100	68
Read as:	4	d

Example of the behavior when typing out numpad 0 - 9

Type	Linux	Windows
Virtual Key:	None	96
Read as:	0	0
Virtual Key:	None	97
Read as:	1	1
Virtual Key:	None	98
Read as:	2	2
Virtual Key:	None	99
Read as:	3	3
Virtual Key:	None	100
Read as:	4	4
Virtual Key:	65437	101
Read as:	<65437>	5
Virtual Key:	None	102
Read as:	6	6
Virtual Key:	None	103
Read as:	7	7
Virtual Key:	None	104
Read as:	8	8
Virtual Key:	None	105
Read as:	9	9

Mac testing is required.

Steps to reproduce the behavior:

1. Download the repo and install all dependencies
2. Checkout the branch feature/delimiter-check (This branch has test outputs built in)
3. Run text-script.py while in the textscript cwd
4. Try typing !reload and numpad 0-9

Expected behavior

Text-Script should have interpreted the virtual key codes the same way on all OS's.

Setup

• OS: Linux
• Running feature/delimiter-check from Pycharm

Resources

• Win32API key codes
• Key codes for linux (not consistent with above results)
