whats this at the top?

i was doing some tutorial code on the discord.NET introduction section of the docs and i found they have this:

public class InfoMdoule : ...
{
    [Command("Say")] // < what's this?
    [Summary("Echoes a message.")]  // < what's this?
    public async Task Say([Remainder] [Summary("The text to echo back.")] string echo)
    {
        await ReplyAsync(echo);
    }
}

public class InfoMdoule : ...
{
    [Command("Say")] // < what's this?
    [Summary("Echoes a message.")]  // < what's this?
    public async Task Say([Remainder] [Summary("The text to echo back.")] string echo)
    {
        await ReplyAsync(echo);
    }
}

is this the C# equivalent of a python wrapper? and what would be the use cases for such a thing?

It's an attribute, not a decorator.

It's basically custom metadata you can add onto types, methods, properties, fields. They can be looked up with reflection.

Angius•6mo ago

Or source generators

yeah, in this case those attributes give discord.NET more information about what to do with your code

Tutorial: Define and read custom attributes. - C#

Learn how attributes work in C#. You define custom attributes to add metadata to your code. You read those attributes to learn about the code at runtime

Jimmacle•6mo ago

in this case, treat your method as a command called "say" with a summary, and to use the remainder of the message as the argument to the method

:SCshocked: btw the tutorial youre watching is outdated [Command] has long been replaced with [SlashCommand]

slowly losing itOP•6mo ago

i know the difference between prefix and slash commands ah ok i think i understand now

The Fog from Human Resources•6mo ago

its more than that

slowly losing itOP•6mo ago

oh?

The Fog from Human Resources•6mo ago

it introduces the Interaction framework which also opens the way to [ComponentInteraction], [ModalInteraction], proper params and some other stuff the probably easiest way to make a proper discord bot

slowly losing itOP•6mo ago

ah ok so just do slash commands cuz they have more features?

The Fog from Human Resources•6mo ago

You do slash commands because they are more user friendly and have been accepted as the new default At the time bot verification still meant something discord also stopped verifying bots that used text commands

slowly losing itOP•6mo ago

:prettythumbsup: slash command does it still face the syncing problem in dpy where you have to refresh your discord client for new things to appear?

only on rare occasions but thats more of a discord issue a thing i like to do is make a help command that lists all commands as clickable then i dont need to wait for discord to update my cache but its overkill so btw you dont need to force close discord you can just do CTRL + R

yeah i know that 👌
