Argument type: duration

[JohnScience]

The most of Discord bots are expected to provide "mute" and "ban" commands. Their implementation involves juggling with parsing strings just to get so-much-desired duration.

Formats:

"3w 1d 11 [many spaces]h \t30m 20s 5ms"

Methods:

• duration.toWeeks() -> float
• duration.toDays() -> float
• duration.toMinutes() -> float
• duration.toSeconds() -> float
• duration.toMilliseconds() -> float

And perhaps a few aliases:

• duration.toW()
• duration.toD()
• duration.toM()
• duration.toMs()

etc

This would make my bot so much cleaner haha!

Would Commando handle parsing a duration itself or use an external package like moment.js or date-fns to handle it?

[brandonbothell]

It should parse the duration itself. Cutting down dependencies is usually welcome. Edit: I've written some tentative regex (I wrote it on mobile, on a bus). It would look somewhat like this: ```javascript /(\d+)\s*([A-Za-z]+)/g ``` Of course, I don't know how allowing the duration to have whitespace in it would effect arguments after it. We may need to disallow whitespace unless in quotes or brackets or something. Maybe some better regex would solve this problem.

I'm not opposed to using moment, since it covers a lot of possible input formats, and handles localisation. The only problem is it doesn't take the "6mo3d4h50m30s" format... which is something that, ideally, would also accept locale-specific suffixes.

Hi, I am working on a solution to this but I am having difficulty testing it locally. I'm currently attempting to run the test bot included but receiving this error:

 $ node test/bot.js
/Users/madlab/repos/temp/Commando/src/extensions/message.js:7
module.exports = Structures.extend('Message', Message => {
                            ^

    at Module._compile (module.js:652:30)

This is after a npm install and npm install discord.js. I ran into the same errors with npm link to my own bot locally.

NVM I found #215 and figured it out.

Okay I have this mostly done but I can't seem to get the methods working. Just adding them to my DurationArgumentType class doesn't do the trick. I also didn't find any examples of class methods with the rest of the types.

This is the regex I'm using to parse duration in one of my bots, not sure if it's any help to anybody:

^(?:(?<weeks>\d+)w)?(?:((?<days>\d+)d)?(?:(?<hours>\d+)h)?(?:(?<minutes>\d+)m)?)$

E.g. 2w3d4h15m where any part is optional

Moment supports plugins which you can use to define new formats and date-fns lets you define a pattern for parsing dates.

[MagnusHJensen]

I'm guessing this was dropped, by people who tried to make it work?
If so, I would like to give it a shot, and see what I can come up with.
#256 (Was this ever implemented?)

[sriRacha21]

I've given this a shot using code from my own bot (#366). I think this would make a great addition to Commando and would love to see any of the suggested implementations merged!

I have the same errorhttps://prnt.sc/1tkskl4
