c++ is a fat cunt compared to c
lyric mountain
What matters is the coder, not the language
split hazel
ive seen c++ and c code alike
wheat mesa
Java is generally slower due to the large use of the heap rather than stack
split hazel
not in this case
wheat mesa
Everything is allocated on the heap except primitives iirc
split hazel
im trying to do something that i cant do because c++ will not allow me
wheat mesa
(Pretty much)
lyric mountain
JVM deals with it natively, so the only difference is where the code is ran
You won't get better performance just because a language is lower level
wheat mesa
Java is partially interpreted is it not?
lyric mountain
Java is black magic
modest maple
im trying to do something that i cant do because c++ will not allow me
C++ will let you do anything
split hazel
and i cant even use inline assembly because A that uses a flavour of assembly i greatly dislike and B C++ does not care about preserving your assembly
lyric mountain
A shitty C code will be slower than a good python code
modest maple
Have you possibly considered the fact that you might be the issue rather than the language?
wheat mesa
Yes that’s true but anybody with half a brain writing C will outperform python 99 times out of 100
split hazel
what are you even talking about
try perform a jump to another function in c++ without using a return
lyric mountain
Java is partially interpreted is it not?
I mean, it has JIT, but it works differently from everything
split hazel
it will result in the stack not being released and objects not being freed
lyric mountain
Noone knows how jvm works, the ancient civilization who created it is long lost

Noone knows how jvm works, the ancient civilization who created it is long lost
Is that why it never seems to get better
split hazel
Then free them 4head
that would have to make my code break if i change the optimisation level
modest maple
it will result in the stack not being released and objects not being freed
On the otherhand, C just don't free anything and will just let everything be free 
Anything you can do in C you can do in C++, normally with the added bonus of having abstractions written by people smarter than you

I have an issue, I have made some custom bots for a server I am an admin in and it was hosted properly, it was running smoothly for 2 months now without any issues but all of a sudden, I am receiving rate-limited errors even tho the bot was working fine for the last 2 months, note, one of the 4 bots only has one function and that is creating member profiles and it is rarely used so that makes it even more weird
even my public bot that has been online for 5 months started receiving such errors, idk what's cause all of this
lyric mountain
Is that why it never seems to get better
Jokes aside, it did improve a lot in the last years

You don't control that, writing it in C isn't going to make it better
split hazel
just because it can run it does not mean it can produce code with the environment in mind
modest maple
or more accurately, you shouldn't try to control it
wheat mesa
There’s probably a good reason it doesn’t store things in registers
modest maple
you think you know more than the 40 years worth of optimisations and development of your compiler?
wheat mesa
C++ isn’t a new language
split hazel
for example the register keyword in c++ used to hint to the c++ compiler to store something in registers as much as it can until it cannot
now it does nothing
wheat mesa
Compiler (usually) knows best
modest maple
you're like the over protected Mom at the doctors trying to tell the surgeon how best to fix your son's heart
wheat mesa
Even some of the simple optimizations that modern C/C++ compilers make now are impressive
split hazel
anyways lets start from scratch
what i was expressing first is that I would use assembly instead of c++ to write the scheduler code because the compiler does not take into account what I am trying to do - it does not know it has to preserve the contents of the registers, it does not know it has to release objects on the stack and heap which leads to a memory leak due to me throwing in inline assembly code which the compiler does not take into account
in other words it really is too high level for what i am trying to do
but if I were to sacrifice c++ i will struggle trying to implement classes I made such as maps and dynamic arrays in assembly
the compiler can do that in an instant
modest maple
writing your own assembly for this application is not a good idea
split hazel
you could say "use function calls" - i am actually trying to avoid them because they add unnecessary overhead

wheat mesa
he said "but node can handle it nowadays"
but..but.. that’s fundamentally wrong!
lyric mountain
hell even scratch I don't doubt
wheat mesa
iirc node runs a couple threads internally but you only have access to one
Workers are the way to go with “multi threading”
lament rock
I mean. It literally is multithreading
just not very customizable considering they don't share the same memory space, so require cache go brrr
wheat mesa
I’ve never really done multithreading in js since it’s not a language really... designed for such a thing
lament rock
I remade LavaLink in js, so I had to use it
lyric mountain
multithreading with node is like releasing a bunch of boats at the same time, then trying to put them together later on

split hazel
its interesting to know that people prefer static typing which was a thing at first due to different types having different sizes which does not work well in a packed structure such as the stack
dynamic typing is supposed to be an advantage
earnest phoenix
So whats the diff between statically typed and the other one
split hazel
javascript stores variables on the heap doesnt it
sudden geyser
yeah but nowadays people like static typing for safety and convenience like autocompletion
split hazel
not sure
sudden geyser
but type systems tend to be terrible for information systems, like representing a user class
split hazel
yeah it is safe
modest maple
javascript stores variables on the heap doesnt it
everything is on the Heap in JS
split hazel
and better documentation
wheat mesa
Everything has an underlying type either way
sudden geyser
yes, but dynamic systems don't force that type constraint
lyric mountain
So whats the diff between statically typed and the other one
statically = WAY easier debugging and stronger compile-time checking
wheat mesa
Dynamic typing is just types checked at run time
modest maple
you mean statically right?
wheat mesa
You’re still fucked if you screw up a type, it just might not crash or be as strict on it
sudden geyser
Dynamic typing is just types checked at run time

just do `System.getenv("name")`
wdym by init file?

export is how u do it in a bash file
you could do a env file too, it's up to u how u do it
just remember to gitignore it
earnest phoenix
yea
lyric mountain
to get the file just do File f = new File("path");
or var f = new File("path"); if u want
although I dislike var
earnest phoenix
Does it not pickup on the env file being there?
lyric mountain
only if u use a lib to auto load it
earnest phoenix
something like dotenv-java?
lyric mountain
probably
earnest phoenix
okie thanks
lyric mountain
I'd still use a bash/batch file for that
since they're already built-in and works just as fine
lyric mountain
you can always press the green arrow next to main method
earnest phoenix
Dont I have to run it from the bash script ?
earnest phoenix
oh?
earnest phoenix
and I can just do System.getenv("TOKEN")?
lyric mountain
ye
earnest phoenix
sweet let me try that
The one thing throwing me off with java is the use of ;
so used to not really having to care
lyric mountain
you get used to it
earnest phoenix
So do you not use try/catch when handling exceptions?
My IDE completely just deleted the try/catch
earnest phoenix
Oh?
lyric mountain
Exception which is the father of all, NEEDS to be catched
and RuntimeException, which is an exception that might happen, doesn't need to be catched
earnest phoenix
So LoginException is what exactly?
lyric mountain
java doesn't allow u to catch something impossible to happen
lyric mountain
So LoginException is what exactly?
press ctrl+Q
see the hierarchy
but everything extends Exception
loginexception is if u put an invalid token probably
earnest phoenix
Ic so there really is no need to catch it?
lyric mountain
you need to
u can also just throw it
public static void main(String[] args) throws LoginException {
btw, jsut write psvm and press ctrl + space
earnest phoenix
public static void main(String[] args) throws LoginException {
JDABuilder builder = JDABuilder.createDefault(System.getenv("TOKEN"));
builder.setCompression(Compression.ZLIB);
builder.enableCache(CacheFlag.MEMBER_OVERRIDES);
builder.setEnabledIntents(GatewayIntent.GUILD_MEMBERS, GatewayIntent.GUILD_MESSAGES);
builder.build();
}
My IDE simply did throws LoginException just now
lyric mountain
ye
u don't need that btw
public static void main(String[] args) throws LoginException {
JDA bot = JDABuilder.createDefault(System.getenv("TOKEN"))
.setCompression(Compression.ZLIB)
.enableCache(CacheFlag.MEMBER_OVERRIDES)
.setEnabledIntents(GatewayIntent.GUILD_MEMBERS, GatewayIntent.GUILD_MESSAGES)
.build();
}
it's a builder, u can just chain
earnest phoenix
Ah
lyric mountain
and afaik, u don't need to set compression
lyric mountain
there are many ways to make one, for instance u can just make an interface and extend all commands from it
then store command instances in a map
earnest phoenix
Mmm, I think I get the idea
lyric mountain
public interface Command {
public void execute(JDA bot, Message message);
}
public class Ping extends Command {
@Override
public void execute(JDA bot, Message message) {
message.getTextChannel().sendMessage("Ping!").queue()
]
}
public class Hi extends Command {
@Override
public void execute(JDA bot, Message message) {
message.getTextChannel().sendMessage("Hello!").queue()
]
}

Unless you mean to add the commands to the command map in the command classes themselves
solemn latch

guessing you know its an existing webhook?
lyric mountain
I am curious though where you would make this map?
I put it in a class of its own
proven lantern
guessing you know its an existing webhook?
yeah, i have an interaction url endpoint that gets the webhook info so that should be existing
lyric mountain
public class CommandHandler {
public static final Map<String, Command> commands = Map.of(
"ping", new Ping(),
"hi", new Hi()
)
}
something like that
obviously you can make it much more dynamic and allow aliases and shit
but that's an example
earnest phoenix
I don't think i have the knowledge currently to make an alias system
lyric mountain
yeah, go slow
earnest phoenix
I could possibly make that automatic tho.
earnest phoenix
```java
public class CommandHandler {
public static final Map<String, Command>...
this I mean
Unless I can't loop through files and get the command names and then the command's class itself
Eh that is too much for now tbh I can't be bothered to figure out how to make it reccursive lookup
lyric mountain
if doing with a list ```java
public class CommandHandler {
private static final List<Command> commands = List.of(
new Ping(),
new Hi()
);
public Command getCommand(String name) {
return commands.stream()
.filter(cmd -> cmd.getName().equalsIgnoreCase(name))
.findFirst()
.orElse(null);
}
}
for aliases it'd be the same, you just need to make a containsIgnoreCase
lyric mountain
there are all 3 types of collections
earnest phoenix
cause in the message listener I can lookup commands by name and run their exec method no?
lyric mountain
List, Map and Set
themselves have a shitton of specializations
like ConcurrentList
also, it's almost a must, INSTALL APACHE UTILS libs
at least collection and string utils
they are so useful
earnest phoenix
if doing with a list ```java

Also I assume getName would be a method in the command's class
lyric mountain
ye
and overriden in each command
the advantage of interfaces is that u can have multiple files share a common signature
so u don't need to cast each command separately
earnest phoenix
So java classes don't work how i thought
How exactly would you provide a name for the command if Command interface specifies one needs to be set
lyric mountain
public interface Command {
public void execute(JDA bot, Message message);
public String getName();
}
public class Ping implements Command {
@Override
public String getName() {
return "ping";
}
@Override
public void execute(JDA bot, Message message) {
message.getTextChannel().sendMessage("Ping!").queue()

there are ways you can decrease that
the one I like most is annotations
@Info(name = "ping")
public class Ping extends Command {
@Override
public void execute(JDA bot, Message message) {
message.getTextChannel().sendMessage("Ping!").queue()
]
}
then just get the annotation of the class
but that's a more advanced concept, you'll get to it eventually
earnest phoenix
I see, also extending an interface isn't something you should do right? I thought you used implements
earnest phoenix
'onEvent(GenericEvent)' cannot override 'onEvent(GenericEvent)' in 'net.dv8tion.jda.api.hooks.ListenerAdapter'; overridden method is final What the heck does this mean?
Aren't you supposed to use @Override on methods in the class that extends ListenerAdapter
lyric mountain
onEvent shouldn't be overriden
there are more specialized events like onGuildMessageReceived
earnest phoenix
Mmm, so the readme on jda's github is wrong
I am trying to use the ready event
aha
lyric mountain
onReady
just type on and press ctrl space
all events will appear there
u can also press ctrl + O

I love the handy
import commands.*
So I dont have to make a new import per command
earnest phoenix
So much about intellij I dont know
lyric mountain
it only gets better over time
also, try to make that bot open source
after 3 months, if you're still actively contributing to it you can grab a free jetbrains license
you get to keep it for as long as you develop
earnest phoenix
Yea I was planning on making it open source
Hopefully people who know java better than me can fix stuff I did poorly at and I can learn from it
lyric mountain
Don't worry abt it too much, you'll get better over time
Just keep ur tokens safe
earnest phoenix
so I noticed the orElse(null) doesn't actually let it return null if nothing is found so how can I check if getCommand returned nothing in the message event
lyric mountain
That's a peculiarity of grabbing a single element from a stream
You COULD just use .get(), but it's not advisable to do so
Since it'll throw an exception
earnest phoenix
I see
earnest phoenix
I am just wondering how exactly to check if getCommand actually returned a result
cause if it didn't obv they can't execute a command
lyric mountain
Check for null
orElse(null) makes it return null if not found
It returns whatever is inside the parens
earnest phoenix
String cmdName = event.getMessage().getContentRaw().substring(1).split(" ")[0];
String[] args = event.getMessage().getContentRaw().substring(1).split(" ");
Command command = CommandHandler.getCommand(cmdName);
if(command == null) return;
command.execute(event.getJDA(), event.getMessage(), args);
so something like this then?
Lets go!

Should both of these work?

ternary operator can work kinda

You can make a getOr method

Mmm
lyric mountain
I always make one

I was using kotlin before but there was a shit ton of issues I had

kotlin is fun
proven lantern
or akka
sudden geyser
but I'd rather use java
earnest phoenix
One of them being how annoying it was to compile donw into a usable jar file
wheat mesa
I was considering making one in c# but I'd rather use java because it's easier with cross-platform compatibility in case I wanna throw it on to a vps
lyric mountain
You could also use groovy
Both java and c# can run groovy
Groovy is technically java with dlc
earnest phoenix
```java
public static <T> T getOr(T get, T or) {
return get == null ? get : or;...
Mmm but how would that working with multiple things? Cause what I want to do is get a member by mention, if that fails get by id, if that fails get by name, if that fails just get the user who initiated the command
lyric mountain
Mmm but how would that working with multiple things? Cause what I want to do is ...
Utils.getOr(something, fallback);
wheat mesa
Both java and c# can run groovy
more complicated, also a language that I'm not very interested in using
java is what I have to learn in school atm
might as well use it in some projects
lyric mountain
Ah fair then
earnest phoenix
`Utils.getOr(something, fallback);`
yea I understand how the method works
earnest phoenix
maven is alright
lyric mountain
I like gradle
wheat mesa
probably a lot easier to use one of those than another with no documentation on how to use it
lyric mountain
It's pretty simple once u understand
earnest phoenix
So far I like the simplicity of using maven
wheat mesa
I'd rather use gradle than maven tbh
earnest phoenix
`Utils.getOr(something, fallback);`
I still don't get how it can help solve the issue I am facing tho? Unless I chain the getOr somehow?
lyric mountain
U could make it accept infinite args
earnest phoenix
Mmm
lyric mountain
public static <T> T getOr(T... opts) {
for (T t : opts) {
if (t != null) return t;
}
return null;
}
There are many ways to approach that
earnest phoenix
I was using that I think
proven lantern
can orElse be chained?

Member member = message.getMentionedMembers()

.orElse(message.getGuild().getMembers()
.stream()
.filter(mem -> mem.getId() == args[1])

message.getMember()

);
Idk if this is efficient at all but I found this works
lyric mountain
Ye, 4 types
proven lantern
i think
lyric mountain
Consumer, Function, Runnable and Callable
Consumer and Function have Bi and Tri versions
And as anything else, u can make ur own
Never tried with var tho
sudden geyser
it should work
given they allow variables with multiple types when using var
with that lambda -> stuff
earnest phoenix
Member member = message.getMentionedMembers()
.stream()
.findFirst()
.orElse(message.getGuild().getMembers()
.stream()
.filter(mem -> mem.getId() == args[1])

.orElse(
message.getGuild().getMembers()
.stream()
.filter(mem -> mem.getUser().getName() == args[0])
.findFirst()
.orElse(message.getMember())
)
);
Something about this just seems inefficient
But idk
sudden geyser
it's just type inference made simple
lyric mountain
You could do this:
proven lantern
nesting is a code smell

it's good that you noticed it looks inefficient
nesting like that should set off alarm bells

mbs = message.getGuild().getMembers().stream()
.filter(mb -> mb.getId().equals(args[0]))
.toList();
} else {
mbs = members;
}
Member member = mbs.get(0);
But I don't know any other way as of right now to make this more efficient
lyric mountain
Members would be mentioned members
earnest phoenix
I see
But how does that help this situation wouldn't I still need to use streams?
I'd end up doing what I was doing before
lyric mountain
Not at all, you get a member at the last line
Ah wait, yeah you'd need to filter it
earnest phoenix
Mmm, but I don't want to only get by mention
I want to get by ID or name as well
and if no mention, name or id is provided it would use the member who initiated the command
earnest phoenix
Yea thats cool, but again I don't only wanna check by id
I'd end up needing to nest again wouldn't i?
lyric mountain
No prob, just add a OR conditional there
proven lantern
do you think java will ever allow if/else statements be assigned to a variable like scala does?
lyric mountain
Like?
lyric mountain
Elvis is in groovy
proven lantern
String x = if(true) {

where everything is an expression
lyric mountain
That's just a ternary
white anvil
rust does this too
lyric mountain
U can do that with switch btw
white anvil
extremely convenient
sudden geyser
yeah now imagine if you could do that with any construct

it can only do it with a few constructs
white anvil
you can do it with anything because blocks can be assigned to variables

that's just a scope
lyric mountain
String val = switch (type) {
case "a" -> "Hello";
case "b" -> "funny";
case "c" -> "big";
case "d" -> "world!";
};
you can do that with any language as well
white anvil
not all languages allow you to return from a scope into a variable
white anvil
does it?
proven lantern
that's invalid syntax
earnest phoenix
No prob, just add a OR conditional there
So i'd use a ternary operator?
white anvil
that’s not assigning the return value of a block to a variable though
lyric mountain
List<Member> mbs;
if (members.isEmpty()) {
mbs = message.getGuild().getMembers().stream()
.filter(mb -> mb.getId().equals(args[0]) || mb.getName().equals(args[0]))
.toList();
} else {
mbs = members;
}
Member member = mbs.get(0);
but basically the point is very expressive languages like those in the lisp family have little to no keywords
lyric mountain
Although for that I'd make an utility method
sudden geyser
so you can do things like { return 5; }
lyric mountain
My Helper class has more than 10k lines cuz utility

lyric mountain
Less words, more parens
sudden geyser
or
(if true
(let [x 5]
(+ x 5))
(or false true))
Which basically reads, if true, return x (5) plus 5 (10), else check if false || true. In a lot of languages, if, let, +, and or are keywords
sudden geyser
how did you get it to 3000
white anvil
lisp might be expressive but it’s horrible to read
sudden geyser
for a helper class
white anvil
lol
lyric mountain
Utility
sudden geyser
lisp is actually quite beautiful once you get used to it
proven lantern
that’s not assigning the return value of a block to a variable though
yeah, you need to use function scope to do that

if(command instanceof Command) {
command.execute(event.getJDA(), event.getMessage(), contents);

``` so I assume this then?If so then that is sick
It negates me having to check for null myself

In that case u could just do command != null
Since it's guaranteed to return something that extends Command

Trim the arg then
Actually, how did u split it?
Orrr, maybe it didn't cache members

String[] contents = event.getMessage().getContentRaw().substring(1).split(" ");
that removes the prefix from the command and returns the cmdName with the arguments

Orrr, maybe it didn't cache members
I was thinking that just now
earnest phoenix
I enabled the intents and the cache flag

That returns null if index doesn't exist
public class <T> LenientList<T> extends ArrayList<T> {
@Override
public T get(int index) {
try {
return super.get(index);
} catch (Exception e) {
return null;
}
}
}
Same for all other access methods
And to convert an array into list: LenientList<String> list = (LenientList<String>) List.of(args)
sudden geyser
you forget to check for negatives
earnest phoenix
java.lang.ClassCastException: class java.util.ImmutableCollections$List12 cannot be cast to class structure.LeniantList (java.util.ImmutableCollections$List12 is in module java.base of loader 'bootstrap'; structure.LeniantList is in unnamed module of loader 'app')
Mmm it has an issue with
LeniantList<String> list = (LeniantList<String>) List.of(contents);
earnest phoenix
If you have the time, could you explain what that error means exactly?
lyric mountain
Or just make a custom constructor for LenientList
lyric mountain
If you have the time, could you explain what that error means exactly?
List.of() returns an immutable list, it's basically final and can never be changed
The error comes cuz we didn't implement it
So it can't be cast
earnest phoenix
Do `new ArrayList<String>(List.of(args))`
Well this wouldn't work anyway there would be a type issue
lyric mountain
That was a quick example I did, there is a lot of improvement to be done to reduce verbosity
lyric mountain
Well this wouldn't work anyway there would be a type issue
ArrayList can be cast
Cuz we extended it
earnest phoenix
Ah right
earnest phoenix
I already tried that aha
It told me it expected 0 but got 1
LeniantList<String> list = (LeniantList<String>) new ArrayList<String>(List.of(contents)); even when doin this same error
lyric mountain
public class <T> LenientList<T> extends ArrayList<T> {
public LenientList(List<T> values) {
super.addAll(values);
}
public LenientList(T... values) {
this(List.of(values));
}
@Override
public T get(int index) {
try {
return super.get(index);
} catch (Exception e) {
return null;
}
}
}
Then just new LenientList<>(args)
You do need to override the other methods present in ArrayList btw, to guarantee you treated all data accesses
Also, List<String> list = new LenientList<>(args) is valid
It'll keep the exception handling but allow to be passed as a generic list
No need to keep repeating LenientList
earnest phoenix
Ayo that works lets go
public LenientList(List<T> values) {
super.addAll(values);
}
public LenientList(T... values) {
this(List.of(values));
}
Can you explain how these two work?
Does the first one just allow you to give it your own list
lyric mountain
The top one is the actual constructor, since we extended ArrayList it contains all method of it
earnest phoenix
and the second let you give it stuf to make a list?
lyric mountain
addAll adds all the content from a list into it
earnest phoenix
Ah
lyric mountain
So when creating a new LenientList, we add all the passed values as initial content
The bottom constructor is an alternate constructor that calls the other one
This allows both a List and an array to be passed
lyric mountain
Ye
earnest phoenix
and if that isn't it will throw a type error?
lyric mountain
And since we declared a varargs there, zero arguments is also valid
Which will result in an empty array
earnest phoenix
LenientList is very useful not only for just the arguments but for other things as well
I wish it was an actual built in java list
lyric mountain
and if that isn't it will throw a type error?
It won't even compile, T is the list type
earnest phoenix
Ah
lyric mountain
so LenientList<T> becomes LenientList<String> in this case
which only accepts String as values
this is the magic of generics
to have a "whatever" list, u could use LenientList<Object>
earnest phoenix
I see java heavily uses Generics unlike ts where you didn't really need to
lyric mountain
which allow all types of data
lyric mountain
I see java heavily uses Generics unlike ts where you didn't really need to
generics are also fun cuz u can have less-generic generics
like public <T extends Command> void addCommand(T command)
it'll only allow classes which extend Command
or implements, same thing
earnest phoenix
Ic
Also
public class <T> LenientList<T> extends ArrayList<T> {
what is the point of <T> after class cause my IDE doesn't like it being there
I had to remove it
lyric mountain
I forgot how to define generics in classes kekw
lyric mountain
<T> defines generic extension
