AttributeError: 'int' object has no attribute 'isdigit'

[PlanetB-rgb]

Describe the bug
User receives AttributeError: 'int' object has no attribute 'isdigit' when manually entering array_sizes for parameters.

To Reproduce
Steps to reproduce the behavior:

1. undef OS_MAX_PATH_LEN
2. Edit CHeaderParser-hdr-paths.txt and remove # on fm_msgdefs.h and fm_msg.h
3. Run python3 CHeaderParser.py
4. Enter the file name to save, I chose fm_app_cmd_file
5. Type yes
6. Pick a command with parameters which contains usage of OS_MAX_PATH_LEN e.g. I am choosing FM_DECOMPRESS
7. Choose the appropriate struct e.g. 10
8. Choose the line containing OS_MAX_PATH_LEN e.g. 2
9. Enter any value for OS_MAX_PATH_LEN
10. See error below

Expected behavior

Traceback (most recent call last):
  File "CHeaderParser.py", line 451, in <module>
    while not array_size.isdigit() or int(
AttributeError: 'int' object has no attribute 'isdigit'

                            if not array_size.isdigit():
                                print("Could not translate",
                                      array_name_size[1])

                                )

                                pass  # Ignore non-integer and try again

• Hardware: VirtualBox
• OS: Ubuntu 20.04
• Versions [e.g. cFE 6.6, OSAL 4.2, PSP 1.3 for mcp750, any related apps]

Fix

I believe the fix to be to remove int on the input function on line 462 : https://github.com/nasa/cFS-GroundSystem/blob/main/Subsystems/cmdGui/CHeaderParser.py#L462 like so:

                        while not array_size.isdigit() or int(
                                array_size) not in range(129):
                            # User input is not an integer
                            if not array_size.isdigit():
                                print("Could not translate",
                                      array_name_size[1])
                            else:
                                print(
                                    "Array size out of bounds. It must be between 0 and 128."
                                )
                            try:
                                # Try to translate user input to an integer
                                array_size =  input(
                                        (f"Please enter the defined value for "
                                         f"{array_name_size[1]} (0 - 128): "))
                            except ValueError:
                                pass  # Ignore non-integer and try again

Additional context

If you want to maintain the array_size as type int you can set the array_size to int array_size = int(array_size) after that while block above.

I tested this on my end with FM commands and an unset OS_MAX_PATH_LEN
