Question

Hello guys My program calls a function inside a coroutine which calls a plugin Now this plugin requires to wait for a specified period of time I tried java util Timer and it didnt work i put 60 secs but even after that it didnt work Now i think i ll try this <https kotlinlang org api latest jvm stdlib kotlin concurrent java util timer schedule html> But what Im unsure about is that if a plugin can have a coroutine call inside it also im not sure if Schedule is a coroutine thingy Thanks

marstran · Answer

`Timer schedule` is not a coroutine construct What kind of plugin are you talking about

otakusenpai · Answer

its a simple plugin which processes text and returns a value

otakusenpai · Answer

the text can hav a string like 60s or 450D

otakusenpai · Answer

i process tht string into seconds then passed it to Timer schedule

marstran · Answer

Do you mean a library Can you give some example code

otakusenpai · Answer

well its a messy bit of code

marstran · Answer

I think I just need to see the API of that plugin

otakusenpai · Answer

marstran · Answer

So onCommand is the function you wait for

otakusenpai · Answer

no onCommand is a general function tht always returns a string That command takes a string as parameter and processes it and then returns some other string

otakusenpai · Answer

currently tht part of the code isnt updated to the repos but heres a snippet

else if strList get 1 == ban var found = false if size lt = 3 retData = Usage $ specialChar chan ban channel prefix or + $ specialChar chan ban channel prefix except or + $ specialChar chan ban channel prefix time or + $ specialChar chan ban channel prefix except time + Time can be in the following format 6D or 6d day 10M or 10m minute + Following are some common literals for time Second s S Minute m M Hour h H Day d D + Others need not be implemented type = 1 else if size gt 3 for i in channelList if i retName == strList get 2 if size == 4 1st if isPrefix strList get 3 retData = SendBan strList get 2 strList get 3 type = 2 else if size == 5 2nd n 3rd if isPrefix strList get 3 if isPrefix strList get 4 2nd retData = SendBanwithExcept strList get 2 strList get 3 strList get 4 type = 2 else if parseTimeInput strList get 4 third 3rd val data = parseTimeInput strList get 4 val timeSecs = setTimeInNumbers data second Timer schedule timeSecs retData = SendBan strList get 2 strList get 3 else if size == 6 if isPrefix strList get 3 amp amp isPrefix strList get 4 amp amp parseTimeInput strList get 5 third val data = parseTimeInput strList get 4 val timeSecs = setTimeInNumbers data second Timer schedule timeSecs retData = SendBanwithExcept strList get 2 strList get 3 strList get 4

marstran · Answer

Put the code inside triple backticks ```

otakusenpai · Answer

```else if strList get 1 == ban var found = false if size lt = 3 retData = Usage $ specialChar chan ban channel prefix or + $ specialChar chan ban channel prefix except or + $ specialChar chan ban channel prefix time or + $ specialChar chan ban channel prefix except time + Time can be in the following format 6D or 6d day 10M or 10m minute + Following are some common literals for time Second s S Minute m M Hour h H Day d D + Others need not be implemented type = 1 else if size gt 3 for i in channelList if i retName == strList get 2 if size == 4 1st if isPrefix strList get 3 retData = SendBan strList get 2 strList get 3 type = 2 else if size == 5 2nd n 3rd if isPrefix strList get 3 if isPrefix strList get 4 2nd retData = SendBanwithExcept strList get 2 strList get 3 strList get 4 type = 2 else if parseTimeInput strList get 4 third 3rd val data = parseTimeInput strList get 4 val timeSecs = setTimeInNumbers data second Timer schedule timeSecs retData = SendBan strList get 2 strList get 3 else if size == 6 if isPrefix strList get 3 amp amp isPrefix strList get 4 amp amp parseTimeInput strList get 5 third val data = parseTimeInput strList get 4 val timeSecs = setTimeInNumbers data second Timer schedule timeSecs retData = SendBanwithExcept strList get 2 strList get 3 strList get 4 ```

marstran · Answer

You can edit your original comment wink

otakusenpai · Answer

```Timer schedule timeSecs retData = SendBan strList get 2 strList get 3 ```

otakusenpai · Answer

this part of the code needs to execute SendBan and wait for timeSecs seconds

otakusenpai · Answer

idk i dont remember what schedule did

otakusenpai · Answer

can you show me a example of <https kotlinlang org api latest jvm stdlib kotlin concurrent java util timer schedule html>

otakusenpai · Answer

like how do you put a function call and store data in a variable at the same time

marstran · Answer

You re kinda prone to race conditions when you assign stuff to `retData` like that

otakusenpai · Answer

ok

otakusenpai · Answer

so should i declare a val somethingFoo = SendBan and then at the end of the onCommand assign tht variable to retData

otakusenpai · Answer

or is there a better way

marstran · Answer

Also the timer will probably fire long after you have returned from your function so at that time the `retData` variable no longer exists

marstran · Answer

Assuming `retData` is defined inside your function like it is in `onCommand`

otakusenpai · Answer

basically the idea is this the if statement checks ban calls SendBan and waits timesecs then sends a SendUnban

marstran · Answer

Ok Instead of assigning the `SendBan` to a variable I think you should send it as a message on a channel

otakusenpai · Answer

like how

marstran · Answer

The component which is reading from `retData` should instead subscribe to the channel and act on the `SendBan` message

otakusenpai · Answer

ok

otakusenpai · Answer

so how do i create this channell is it a coroutine or something

marstran · Answer

marstran · Answer

I guess you could use an actor

marstran · Answer

You should read this document <https github com Kotlin kotlinx coroutines blob master coroutines guide md>

marstran · Answer

You can read about both channels and actors there

otakusenpai · Answer

ok

otakusenpai · Answer

so can you tell me what basically happens here gt

marstran · Answer

Do you mean with `Timer schedule`

otakusenpai · Answer

no this channel and actor

marstran · Answer

That s too much info to write down in a chat thread wink I think you will find everything you need in that coroutines guide

otakusenpai · Answer

okies

otakusenpai · Answer

thnx

marstran · Answer

No problem

otakusenpai · Answer

also one more thing will using a coroutine inside a plugin do any harm

gildor · Answer

What is plugin What kind harm Coroutines is just an abstraction and library for asyncronous programming

gildor · Answer

If you use coroutines I don t understand why do you need Timer schedule if you can just use `delay` from kotlinx coroutines
