Minimal example of URL validation

[interifter]

In case you wanted to avoid using GHAs for this. I know the point is to make the GHAs work, but it seems like a lot of work for something that can be done with relative ease. I'm sure I missed the point, but when Susan explained what she thinks is happening, I thought "why so many steps?"

And if this is close to the mark, pydantic is very extensible in the kinds of checks you can make with it.

E.g,

All you need to do is run python validate.py ./predefined_url.json

Use Case 1: Happy Path

[
    {
        "url": "https://github.com/altera-fpga/agilex7f-nios-ed"
    }
]

Output

> python validate.py ./predefined_url.json
Model is valid: model=[PredefinedUrl(url=HttpUrl('https://github.com/altera-fpga/agilex7f-nios-ed'))]

Use Case 2: Invalid URL

[
    {
        "url": "github.com/altera-fpga/agilex7f-nios-ed"
    }
]

Output

> python validate.py ./predefined_url.json
Traceback (most recent call last):
  File "C:\code\altera-fpga-settings\validate.py", line 37, in <module>
    main()
  File "C:\code\altera-fpga-settings\validate.py", line 32, in main
    model = PredefinedUrl.from_file(predefined_url)
  File "C:\code\altera-fpga-settings\validate.py", line 25, in from_file
    return [cls.model_validate(x) for x in data]
  File "C:\code\altera-fpga-settings\validate.py", line 25, in <listcomp>
    return [cls.model_validate(x) for x in data]

url
  Input should be a valid URL, relative URL without a base [type=url_parsing, input_value='github.com/altera-fpga/agilex7f-nios-ed', input_type=str]
    For further information visit https://errors.pydantic.dev/2.10/v/url_parsing

Use Case 3: Invalid input file

> python validate.py ./predefined_url.jsson
Traceback (most recent call last):
  File "C:\code\altera-fpga-settings\validate.py", line 37, in <module>
    main()
  File "C:\code\altera-fpga-settings\validate.py", line 31, in main
    raise FileNotFoundError(f"Could not find {predefined_url=}")
FileNotFoundError: Could not find predefined_url=WindowsPath('predefined_url.jsson')

Use Case 4: Malformed JSON

[
    {
        "url": "github.com/altera-fpga/agilex7f-nios-ed"
    }

> python .\validate.py ./predefined_url.json

    model = PredefinedUrl.from_file(predefined_url)
  File "C:\code\altera-fpga-settings\validate.py", line 24, in from_file
    data: list[dict[str, str]] = json.load(handle)
