Description

This PR adds the ability for the argument name of an option for slash commands to be different from the option name itself. For example, this example works, despite the difference between test and _test.

@interactions.slash_command(name="test", description="A test command.")
@interactions.slash_option(
    "test",
    "A thing.",
    interactions.OptionType.STRING,
    required=True,
    argument_name="_test",
)
async def test(ctx: interactions.SlashContext, _test: str):
    await ctx.send(_test)

To keep this non-breaking, argument_name/name had to be inserted into the current methods at... awkward positions, but it should work.

Changes

• Introduce a new parameter to SlashCommandOption, argument_name.
  • On its own, it does basically nothing but exist. It's even removed when transformed into a dict, just to not break serialization (and since it isn't a Discord concept).
• Add options to the various ways of declaring slash command options to specify either the argument name or the name of the option as appropriate.
  • If they're not given, they default to their old behavior.
• Add an extra final step to parsing parameters for slash commands to find options with argument_name specified and essentially link SlashCommandParameter and the actual option name through it. Of course, this required a new parameter to SlashCommandParameter.
• Slightly adjust the callback logic to handle the translation between the two names smoothly.
• Make hybrid commands respect this logic (or, well, be able to handle it at least).
