Dashed arguments / flags handler?

[nabtron]

How can we create dashed arguments / flags handler? is there any builtin func for that or any recommended library?

For example, how to handle this command:

!show -id 22 -cat 32
Thank you.

Well, Discord slash commands support options like this so I don't understand what's the problem

Flags come from command line interfaces and are used for optional input (which generally goes against your example here, since these seem to not be optional). There are boolean flags --verbose / -v and argument flags --port 8080 / -p 8080, sometimes also with non-space delimiters --port=8080.

With slash commands, flags are completely obsolete. Instead, you would model this with a slash command named "show", with optional parameters id (number) and cat (number).

For optional input, you can use .setRequired(false), if using the builders as recommended in this guide section: https://discordjs.guide/interactions/registering-slash-commands.html#options

@almostSouji so there is no real way to have argument flags in discord.js like we had in discord.py?

I do not see any reason why you would need argument flags for slash commands. Slash commands are precisely designed to avoid usage of flags and unintuitive command usage for the end user. For message-based commands, sure, I can see the use case there. You can look into node libraries to parse command line input fort this (for example https://www.npmjs.com/package/lexure).

The future of Discord applications clearly points towards slash commands as the preferred interface. Optional boolean flags are easily possible with https://discordjs.guide/creating-your-bot/creating-commands.html#registering-commands
