How to extend SchemaGenerator for DateTime about json-everything HOT 7 CLOSED

There's an example in the documentation.

https://docs.json-everything.net/schema/examples/generator/

from json-everything.

formats.date and formats.datetime don't work for these formats

from json-everything.

Please see
dotnet/runtime#85545

You may need to use pattern instead.

format is an annotation anyway. It doesn't validate.

from json-everything.

I got this: The string value is not a match for the indicated regular expression
when I have date like 2023-06-15T13:45:30 and this schema generator

internal class DateTimeSchemaGenerator : ISchemaGenerator
{
    public bool Handles(Type type) => type == typeof(DateTime) 
                                   || type == typeof(DateTimeOffset)
                                   || type == typeof(DateOnly)
                                   || Nullable.GetUnderlyingType(type) == typeof(DateTime)
                                   || Nullable.GetUnderlyingType(type) == typeof(DateTimeOffset)
                                   || Nullable.GetUnderlyingType(type) == typeof(DateOnly);

    public void AddConstraints(SchemaGenerationContextBase context)
    {
        context.Intents.Add(new TypeIntent(SchemaValueType.String | SchemaValueType.Object));
        context.Intents.Add(new PatternIntent(@"^(?:(\d{4}-\d{2}-\d{2})([Tt]|)(\d{2}:\d{2}:\d{2}))$"));
        context.Intents.Add(new PatternIntent(@"^(?:(\d{4}-\d{2}-\d{2}))$"));
    }
}

I think nice to have possibility extend Formats in case

like Register a new format for DateTime

Please, read the documentation.

https://docs.json-everything.net/schema/basics/#schema-format

"New formats must be registered via the Formats.Register() static method. This method will overwrite any existing registration for that format, so this can be used to override the default behavior for known formats."

from json-everything.

I mean to have any needed format like CheckDateFormat(node, "yyyy-MM-ddTHH:mm:ss"); or extend it in SchemaGenerator

I'm not going to do your work for you. You have all of the pieces you need:

• How to add custom formats (including overwriting existing formats). This applies to validation.
• How to add custom generators. This applies to creating schemas.

Moreover, all of this information is included in the documentation and has been for a long time.
