nocturne galleon
I kinda had an argument with him since he got angry at me after I asked him if he'd ever seen a woman
crystal tundra
why would he even message me this tho
it just confused me
what the question was trying to achieve
nocturne galleon
lol reply to him yeah Im cool asf
nocturne galleon
lol
anyone that knows why he would leave
maybe he got too overwhelmed by my apology
crystal tundra
i cant answer it to him
it wont let me
but the real answer is no
i dont think anyone who's ever spoken in this channel can answer yes

Hello, im organizing small game jam event, if anyone would be intrested , dm me 😉
wary acorn
I have been strugling trying to understand this for way too long so if anyone could help me out that would be much apreciated. I am trying to understand how kruskals maze genorator works from this article http://weblog.jamisbuck.org/2011/1/3/maze-generation-kruskal-s-algorithm, and I get the algorithum part but when talking about implementation he says,
Implementing Kruskal’s algorithm is straightforward, but for best results you need to find a very efficient way to join sets. If you do it like I illustrated above, assigning a set identifier to each cell, you’ll need to iterate on every merge, which will be expensive. Using trees to represent the sets is much faster, allowing you to merge sets efficiently simply by adding one tree as a subtree of the other. Testing whether two cells share a set is done by comparing the roots of their corresponding trees.
This makes no sense to me because adding a subtree still only changes one cell, and it dosn't change the root node either witch is what is used for comparisons. So not only would the merged sets not be recognized as the same set, but you would still need to check every cell to see if the tree needed to be modified. What am I missing?

how exactly do I get started with doing front-end development on a site? I explained a bit more what I mean in #off-topic yesterday but I can explain it again here
I and a few others run a big modding community and have someone who has a mod list site for us to list mods there. They have to follow copyright law to be allowed in the sub which this site follows but a splinter site with a better layout doesn't do so and wants to be the main site.
A few are critiquing how the site is shown as like a 90s page so I want to try and learn it to help said good site to appear better than the splinter.
@hazy bobcat learn some css, find a good framework
ask ppl for critique on ur designs, make a nice user esperience

Hello friends!
fervent thicket
If have an array if (a, b, c, d) is it possible to make it in js so it creates every possible combination in like order? Like (a, aa, aaa, b, ba, baa, bb, bba, baby, etc..) ? How would I do such thing or where should I start
hollow basalt
sounds like a homework lel
(a, b, c, d)
How do you create "baby"
I think I know a different permutation

warm sleet
@umbral saffron you are using venv, did you add the dependency?
warm sleet
Yeah, you have to add it as a dependency of your project
otherwise you cant import it
umbral saffron
what does that mean
warm sleet
oof uhm
your project depends on tkinter
so you need to download the code for tkinter
python can do this for you
warm sleet
spring pond
actually its "Interpreter Settings"
warm sleet
@umbral saffron no, you need to add tkinter to your project first
before you can import it
@umbral saffron its a library with code that your program uses
warm sleet
I actually use pip for managing dependencies, not sure how this translates to venv
@spring pond ?
spring pond
its the same thing
sometimes i use venvs, sometimes i use my system install for projects
the interface in pycharm is the same
warm sleet
yeah but how do you tie it into his pycharm instance
spring pond
from what the screenshots have it looks like he already has an interpreter configured
he just needs to add the packages
warm sleet
@umbral saffron close that window
umbral saffron
ok
spring pond
send a screenshot
umbral saffron
spring pond
click on the plus
warm sleet
yea
sudo apt-get install python3.8 python3-tk is what is suggested
but he's on windows
spring pond
you shouldn't need it b/c its in std lib
umbral saffron
wait so what am i doing
spring pond
you shouldnt need to do anything
just tested, it works on 3.9 w/o any install
3.8 shouldnt be any different
warm sleet
@spring pond actually
if you look at his first screenshot
@umbral saffron its already working.
the import is grey because it is not used in code
spring pond
you have no code
warm sleet
imports are grey if unused, and your source file is empty
once you reference tkinter, it will become regular colored, like above^
spring pond
nah u good
umbral saffron
i learned
warm sleet
stupid of me to not notice earlier
xD
if the import didnt exist, it'd be red
@spring pond I only really use python if the shell doesnt cut it for me
its the easiest way to whack together some code
spring pond
yeah definitely
umbral saffron
i use intelliJ but i just played around with it once
warm sleet
@umbral saffron you dont need an IDE for python programming
You could use a regular text editor
spring pond
the intellij family is really nice but it can take a bit to get around
spring pond
yeah its definitely my favorite set if ides
warm sleet
@spring pond I actually used netbeans before
it was the only IDE at the time that had full maven integration
but IDEA is now maven based too
spring pond
i considered using netbeans when i was using eclipse a long time ago but i ended up with idea
warm sleet
@spring pond tbf
netbeans sucks ass
It just, cannot compare to this
JavaEE, Language Injection
spring pond
i see you have ultimate
warm sleet
Yep
spring pond
ive never tried it but ive heard its good
warm sleet
Its same as community
spring pond
it looks like it has a lot more
warm sleet
but you can install other languages as packages
spring pond
oh thats interesting
spring pond
well considering pretty much every other ide that jetbrains has is forked off of this im not surprised
warm sleet
Do you use dependency injection?
IDEA puts little breadcrumbs on the left
for injection points
spring pond
ill be honest i don't really know what that is, i dont use java too often anymore
warm sleet
@spring pond declare interfaces, and any constructors that need instances, use interfaces only
instead of using a factory, you use a dependency injection framework
to bind interfaces to classes
but you can do this runtime
spring pond
oh avoiding factories sounds like a godsend
warm sleet
It also allows you to mark a type as @Singleton
and it will make 1 instance, and remember it
Very useful for unittesting
static singletons are a cancer
spring pond
lol
warm sleet
@spring pond https://i.imgur.com/2fdzKqv.png
So I have my DAO interfaces for the database
and the database properties are just passed to the constructor of the module
spring pond
cool
warm sleet
@spring pond idk if you ever made rest services
spring pond
im working on one right now lol
warm sleet
but the instance that handles the request, is usually created by the webserver
spring pond
granted its in python
warm sleet
how do you pass parameters to the constructor?
spring pond
im using django with django-rest-framework
so im not sure if that applies
im using method-based views with some special annotations
spring pond
yup
warm sleet
if you build applications in java, you'll want to avoid that kind of stuff
spring pond
well the objects is managed by django, i just made the database model
warm sleet
@spring pond with DI, all you do is
@Inject
public PlayerWebService(HighscoreService highscoreService, SpellService spellService,
LivePlayerDao livePlayerDao, FamilyService familyService, DaoProvider provider) {
this.highscoreService = highscoreService;
this.spellService = spellService;
this.livePlayerDao = livePlayerDao;
this.familyService = familyService;
this.provider = provider;
}
you add an @Inject
and if the DI framework wants an instance of PlayerService (the interface)
it looks at the bindings, and sees it creates a PlayerWebService
and the constructor has @Inject
so it looks for instances of each parameter
essentially, the DI framework constructs objects for you
spring pond
so is it reading from the database or where is it creating these objects from
warm sleet
Yeah in this case, I have a DatabaseModule
spring pond
ok
warm sleet
which binds those Dao interfaces to actual classes with code
spring pond
makes sense
warm sleet
@spring pond essentially, 1 package has 1 module
the package defines public interfaces, that are described in the module
and all classes are package private, exposed through the module
hollow basalt
spring pond
i think im following the 1package/module for my set
warm sleet
@spring pond yeah but get this. what if you wanted support for "Two kinds" of databases
spring pond
but ofc python doesnt really have access modifiers
hollow basalt
but ofc python doesnt really have access modifiers
atleast we have double underscore
warm sleet
one module for each DB kind
spring pond
atleast we have double underscore
yeah thats what i was refrencing
warm sleet
so runtime you can do something like if (db == SQL) { bind( new SqlModule())
warm sleet
exactly.
And it also makes wiring up your code lot easier
if you need a database reference
you just add the interface to your constructor
@spring pond https://github.com/google/guice
spring pond
ill be keeping that for later
warm sleet
DI is a thing in almost every OO language
its very useful for applications that have many components
you can write your components as libraries and even share them between projects
you just have to add the module to your injector and you're good to go
This is the principle it tries to fulfill
if you want to get philosophical xD
The goal of the dependency inversion pattern is to avoid this highly coupled distribution with the mediation of an abstract layer, and to increase the re-usability of higher/policy layers.
spring pond
im not super experienced in programming for large applications so a lot of this is going over my head, but it looks interesting
warm sleet
Yeah, it allows you to do interface seperation
spring pond
ok
warm sleet
Cross-package imports should only be on interfaces
warm sleet
When I design a new component
I usually start with an interface
define some methods I want this component to have
then I create an implementation of said interface
and add it to module to I can use it in my application
if you use an interface that isnt bound with a module
you will get an exception
spring pond
makes sense
warm sleet
injector = Guice.createInjector(new DatabaseModule)
injector.getInstance(MyInterface.class)
shy helm
im not super experienced in programming for large applications so a lot of this is going over my head, but it looks interesting
@spring pond lots of big big projects also use Spring for DI
shy helm
mmmm spring
shy helm
hmmm, depends what you're doing
lots of nice things in Spring Boot to make your life easier
Annotations are also nicer
warm sleet
yeah but is it that spring boot does for ya lol
shy helm
wat
warm sleet
Like, what is it that spring boot does that you cannot do normally
shy helm
Write OAuth implementations? 😛
warm sleet
mh
I wrote my own OAuth handler as a servlet filter
its like 30 lines of code
@shy helm I did that
after the existing spring solution was giving me headaches
exceptions in spring internals
and no clear documentation on what to do
shy helm
Like, you built a standard following OAuth handler in 30 lines?
shy helm
It's not that complicated if you do it wrong...
is your system intercompatible with actual OAuth?
or are you just calling it OAuth?
What kind of auth flows did you support?
warm sleet
xD
shy helm
Yeah, I had to do that for Kerberos auth
If you can't fall into the default types of auth spring boot supports it can be a bit painful
shy helm
No disagreement from me there 🙂
But tons of apps will find spring already supports exactly what they want
warm sleet
need minimal amount of code to do it
yeah
I cobbled together my own glue code over the years
to do this as simple as possible
shy helm
Even more complex stuff like handling Kafka is nice on Spring
warm sleet
StandaloneServer(WebserverProperties properties, Injector injector) {
URI baseUri = UriBuilder.fromUri("http://localhost/").port(properties.getPort()).build();
ResourceConfig config = new ServiceConfig(injector);
server = JettyHttpContainerFactory.createServer(baseUri, config);
}
void start() throws Exception {
server.start();
}
the ServiceConfig holds all the jax-rs servlet configuration
Only shitty thing, which makes me want to replace this
Jersey uses HK2 for DI
and I use Guice
warm sleet
netty is a TCP lib
jetty is a webserver
register(new ContainerLifecycleListener() {
@Override
public void onStartup(Container container) {
ServiceLocator serviceLocator = container.getApplicationHandler().getServiceLocator();
GuiceBridge.getGuiceBridge().initializeGuiceBridge(serviceLocator);
GuiceIntoHK2Bridge guiceBridge = serviceLocator.getService(GuiceIntoHK2Bridge.class);
guiceBridge.bridgeGuiceInjector(injector);
}
@Override
public void onReload(Container container) {
}
@Override
public void onShutdown(Container container) {
}
});
shy helm
But if you're using Spring you can use either 😛
warm sleet
this way, I can just use jetty as a standalone servlet engine
warm sleet
@shy helm yeah thats what spring does for you
It provides that servlet context for you
but spring defines a lot of types that are already in the JavaEE standard
Just looking at these docs
I remember why I hate spring
@shy helm http://sparkjava.com/ :D
one my favorite libs
shy helm
I actually heard about Spark Java
warm sleet
Its a lot like expressJS
shy helm
JK Express is not bad

Try building a webserver in Python and cry yourself to sleep
Apparently not a single web framework in Python was well thoughout

With session logins and userroles :D
shy helm
they're all so convoluted and poorly designed

Our 2015 survey tells us that over 50% of Spark users use Spark to create REST APIs, while about 25% use Spark to create websites.
o.O did 25% of their users die
warm sleet
I am that 25%
warm sleet
@GET
@Path("minecraft")
@RequiresLogin
public ModelAndView getMinecraftServerStatus(Request request, Response response) {
Map<String, Object> models = new HashMap<>();
ServiceAPIClient client = session(request).getClient();

models.put("server", info);
models.put("page", "Server Information");
models.put("page_desc", info.getName());
return new ModelAndView(models, "status/minecraft");
}
@shy helm basically ^
like I said, I got bored
but this is as small a controller I could get
I think I used handlebars.js as template engine
hollow basalt
Try building a webserver in Python and cry yourself to sleep
cries in django
warm sleet
@shy helm ok you are right, I did die at some point..
the routing provider is a fucking mess
private static TemplateViewRoute createCall(final Method method,
final Object provider,
final boolean login) {
return (request, response) -> {
try {
if (login && !session(request).login()) {
LoginHelper.login(request, response);
return null;
}
return (ModelAndView) method.invoke(provider, request, response);
} catch (IllegalAccessException | InvocationTargetException e) {
throw new InternalServerErrorException(e);
}
};
}
I think some of my favourite Java code I've ever written, to this day, was some wrapper stuff over the Kafka library
warm sleet
@shy helm now for the terror
return providers.stream()
.filter(p -> !p.isInterface() && !p.isEnum())
.flatMap(p -> {
try {
Path classPath = p.getAnnotation(Path.class);
String path = classPath.value();
Object object = injector.getInstance(p);
Route route = new Route(object);
Arrays.stream(p.getDeclaredMethods())
.filter(m -> m.isAnnotationPresent(GET.class))
.forEach(m -> {
String mPath = "";
if (m.isAnnotationPresent(Path.class)) {
mPath = m.getAnnotation(Path.class).value();
}
m.setAccessible(true);
route.addRoute(
new Tuple<>(
RequestMethod.GET, combinePath(path, mPath)
),
createCall(m, object, m.isAnnotationPresent(RequiresLogin.class))
);
});
Reflection galore
sniffin annotations

We wanted to use protobuf for sterilization, so I had to write a bunch of generic code which allowed you to create and map classes, auto create serde classes, etc
Was very fun to build
warm sleet
@shy helm those are my favorite coding challenges
I've built my own module loader for this one gameserver
runtime reload code
private void loadModule(File moduleFile) throws Exception {
String moduleClassPath = null;
boolean reloadable = false;
try (JarFile jarFile = new JarFile(moduleFile)) {
try (URLClassLoader preLoader = new URLClassLoader(new URL[]{moduleFile.toURI().toURL()}, getClass().getClassLoader())) {
Enumeration<JarEntry> entries = jarFile.entries();
while (entries.hasMoreElements()) {
JarEntry entry = entries.nextElement();
if (entry.isDirectory() || !entry.getName().endsWith(".class"))
continue;
Class<?> clazz = Class.forName(trimClassName(entry.getName()), true, preLoader);
if (isModule(clazz)) {
if (moduleClassPath != null) {
throw new Exception("Module has more than one compatible module class: " + moduleFile.getName());
}
moduleClassPath = entry.getName();
reloadable = clazz.getAnnotation(Module.class).reloadable();
}
}
}
}
Security experts can have a fieldday with this
It basically enumerates all .class files in the jar, loads them into a classloader and checks if the types are annotated with @Module
Whoever said classloaders should be immutable, better come fite me
shy helm
lmao
warm sleet
@shy helm lol but.
shy helm
very secure
warm sleet
the interface is sexy
class CoreModuleLoader extends ModuleLoader<KnockturnCore> {
CoreModuleLoader(KnockturnCore instance) {
super(new File(instance.getDataFolder(), "modules"), instance);
}
@Override
protected void handle(Loadable<KnockturnCore> module, Module meta) {
if (module instanceof CoreModule) {
((CoreModule) module).setVersion(meta.version());
}
printName(meta);
}
...
@shy helm its minecraft so w/e
@shy helm we have big lists of constants that may need to be updated on the fly
thats 350 entries
shy helm
Omg use a config store
warm sleet
lot of our roleplay plugins uses this
shy helm
Even like a nsql DB 😂
warm sleet
@shy helm can't
some families have direct code references
and thats not compilesafe
warm sleet
Family is part of the public API that every developer can use
shy helm
And make it load the config internally
warm sleet
but the Families data, is 'private'
since we don't want to give away our roleplay data to everyone
@shy helm meh, I forget why I didnt use sql at the time
Lot of this data is backed in sql
the java interface behaves like an enum
shy helm
I’ve had to deal with runtime enum creation, it’s not the worst
Our had to pull from a REST API too
warm sleet
static Family valueOf(String name) {
return (Family)StaticDataBinding.getBinding(Family.class).stream().filter((f) -> {
return Objects.equals(f.name(), name);
}).findFirst().orElseThrow(() -> {
return new IllegalArgumentException("No family with that name exists");
});
}
static Family[] values() {
List<Family> families = StaticDataBinding.getBinding(Family.class);
return (Family[])families.toArray(new Family[families.size()]);
}

getMousePosition() -- does things that things that are unrelated
@next igloo usually get implies you return something
updateMousePosition() seems more appropriate :)

when you run my command, a button is supposed to come up on the GUI but theres nothing there

openFile = tk.Button(padx=10, text="Open File", pady=5, fg="White")
root.mainloop()```@umbral saffron you define a function, addApp but you never call it
umbral saffron
oh yea
well i wanted to finish addApp and test it and its supposed to open a GUI that has a button that when u click it it opens ur files
but when it opens
warm sleet
@umbral saffron what do you mean by "opens ur files"
umbral saffron
u click it
and it opens file explorer
or at least u should be
again this was another test
to see if it can open things
but theres no button
@warm sleet
next igloo
@warm sleet the get mouse position function works perfectly and the variables it outputs are correct, i just need the correct jquery syntaxes i think
warm sleet
@umbral saffron is that code above the one thats currently running?
umbral saffron
lol
warm sleet
umbral saffron
did u uninstall it
umbral saffron
ah
warm sleet
sec
import tkinter as tk
from tkinter import filedialog
root = tk.Tk()
def file_dialog(e):
filename = filedialog.askopenfilename(initialdir="/", title="Select File",
filetype=(("executeables", "*.exe"), ("all files", "*.*")))
canvas = tk.Canvas(root, height=700, width=700)
canvas.pack()
openFile = tk.Button(root, padx=10, text="Open File", pady=5)
openFile.bind("<Button-1>", func=file_dialog)
openFile.pack()
root.mainloop()
@umbral saffron
Try this
warm sleet
only weird thing
I couldnt figure out
was why the button looks so weird after you close the dialog
@umbral saffron you basically bind an event handler to the button
and the button wasnt visible
because you didnt pack() it
oh
@umbral saffron ok figured it out
try this:
import tkinter as tk
from tkinter import filedialog
root = tk.Tk()
def file_dialog():
filename = filedialog.askopenfilename(initialdir="/", title="Select File",
filetype=(("executeables", "*.exe"), ("all files", "*.*")))
canvas = tk.Canvas(root, height=700, width=700)
canvas.pack()
openFile = tk.Button(root, command=file_dialog, padx=10, text="Open File", pady=5)
openFile.pack()
root.mainloop()
so you're just supposed to pass the function as command
umbral saffron
ur 1st one worked
warm sleet
yeah
umbral saffron
what
warm sleet
but its not the right way
look at the button
after you close the dialog
it doesnt have an animation
umbral saffron
meaning
warm sleet
you run that bit of code
but doing command=file_dialog you mere pass a reference to that function
with file_dialog() you call the function
umbral saffron
ohh ok
warm sleet
execute, invoke, call
means basically same thing
we're not doing prayers or magic here
umbral saffron
lol
ok so the last thing I wanna try is taking a GUI linking it to a website
so its like a web browser
its a website called wolframalpha
umbral saffron
i think i can figure it out
umbral saffron
well look
warm sleet
you use the wolfram alpha API
umbral saffron
yes thats what i was gonna do
warm sleet
and do your request directly with their servers
umbral saffron
so doing
umbral saffron
import wolframalpha
client = wolframalpha.Client("API")
assert isinstance(client, object)
res = client.query('temperature in miami')
print(next(res.results).text)```doing that would do it
umbral saffron
but i want it so res = client.query('temperature in miami') can be edited and can be typed in a gui
umbral saffron
?
warm sleet
k
umbral saffron
so then how do i make it so it can be edited in a GUI
warm sleet
nah thats not the point
Just saying, I've used wolframalpha before, long time ago
made a little command in a chat channel ,where you could ask for wolframalpha
umbral saffron
thats what im trying to do kinda
warm sleet
yeah
warm sleet
@umbral saffron keep your imports at the top of your file
individual bits of code that you want to run, you put into methods with def
umbral saffron
idk what that means
warm sleet
functions/methods
@umbral saffron imports allow you to access code from other files
in this case, you are importing tkinter and wolframalpha
put this at the top of your file import wolframalpha to import it
then you can create a client with this: client = wolframalpha.Client(app_id)
not sure what that PySimpleGUI is
umbral saffron
i did
warm sleet
wtf
umbral saffron
PySimpleGUI is another tkitner thing
warm sleet
are you just copy pasting random things from the internet?
umbral saffron
what
warm sleet
what is all this crap https://i.imgur.com/HRWsKGO.png
umbral saffron
no im not taking random things
it was a thing based on a tutorial that i edited
is it not needed
@warm sleet
warm sleet
@umbral saffron
import wolframalpha
client = wolframalpha.Client("APP ID")
result = client.query("What is the answer to life, the universe, and everything?")
print(next(result.results).text)
make a new file
put this in there
and try it out
umbral saffron
wait nvm i had the other file still open XD
warm sleet
software is documented
you have to read and try to understand what it is doing
a query is a request for data
and it returns a Results object
which I put in a variable named result
warm sleet
yeah
warm sleet
next() just takes the first item in a list
Results may have more items
for pod in result.pods:
for sub in pod.subpods:
print(sub.text)
this would run through all the results and print them out
logically what you would do is
for pod in result.pods:
do_something_with(pod)
create a new method to do something with the pod
umbral saffron
so the second one makes it cleaner and more info u would want?
warm sleet
Yeah depends on what you need
if you have graphs
or images
I think they are supplied differently
this is just plaintext
umbral saffron
im gonna try the Tkitner thing again
but i only got far enough for 1 button that opens something
warm sleet
@umbral saffron just do this:
warm sleet
def query_wolframalpha(text):
client = wolframalpha.Client("APP ID")
result = client.query(text)
return next(result.results).text
then you can call it from anywhere else in your code
warm sleet
a function, or sometimes called a method
umbral saffron
and using query_wolframalpha lets u use all of that to use the bot
umbral saffron
so this is different thanresult = client.query("What is the answer to life, the universe, and everything?")
warm sleet
yeah thats jsut to show you how it works
but by creating a method for it with def
we can give it an input text
and then use that with the wolfram client
and we then return the answer
umbral saffron
so am I replacing
warm sleet
this is coding 101
umbral saffron
client = wolframalpha.Client("LLJV76-R2T8GERLT8") result = client.query("What is the answer to life, the universe, and everything?") print(next(result.results).text)
warm sleet
You should do a python tutorial
umbral saffron
i was looking at some
warm sleet
codeacademy
umbral saffron
and it led me to the really long code thing
warm sleet
warm sleet
@umbral saffron once you understand how the language works
you'll be able to read and understand what a program is doing
without this, you're kinda aimlessly doing things
python is quite easy
warm sleet
thats not really how its done
You break up your programs into little functions
structure what you are doing
makes it a lot easier to read and write code
@umbral saffron some programs have 1000s of functions
this is one file for one of my projects
all of those are functions
umbral saffron
woah
warm sleet
and if you don't organize things
you end up with spaghetti code
and it just grinds your progress to complete standstill
umbral saffron
so u gotta make sure its organized
umbral saffron
coolloorrrr
warm sleet
omg
haha.

java is a very easy language imo
compared to langs like c++
however it does require a lot more boilerplate than some other languages such as Kotlin
it was the first language i learned
umbral saffron
ok
spring pond
if you're looking to learn a lot of languages, java is a great place to start
python is too
umbral saffron
all i need to do now is make the GUI with text
spring pond
may i suggest qt
its a c++/python library with a lot of features
and the system is quite intuitive
umbral saffron
spring pond
i have ptsd from swing
qt5
thats the version you need
i have some projects i have used qt in if you need examples
umbral saffron
python-qt5 or qt5
spring pond
qt5
warm sleet
@spring pond he should do a tutorial first
umbral saffron
ok
warm sleet
and not slap together random crap from the internet
spring pond
good point
there are quite a few out there
https://build-system.fman.io/pyqt5-tutorial i think this is the one i first used
umbral saffron
wait do i need to update pycharm then it says it couldnt find a version that satisfies the reqirement
spring pond
importing specific elements such as a text box QLabel or a button QPushButton
its later on in the linked tutorial
umbral saffron
but if I import the whole thing doesnt it have all of that
spring pond
well pyqt5 is divided into modules
umbral saffron
oh
spring pond
sample import
from PyQt5.QtWidgets import QApplication, QWidget, QPushButton, QVBoxLayout
pycharm should have prompted you to install pyqt5-stubs
umbral saffron
i think it did
spring pond
if you did it it should give you code completion
umbral saffron
like some pre written code?
spring pond
nah just telling you what the arguments are and stuff like that
umbral saffron
so the qt thing can set up a GUI so it has a text box u can type in
and search it
warm sleet
@umbral saffron if you see words like stub being used
look them up ;)
there's lots of jargon
spring pond
that thing you have highlighted
it adds it to the imports
you dont need to type it in youself
umbral saffron
oh cool
spring pond
also you don't need import PyQt5 as qt
umbral saffron
then what do I do?
spring pond
did you follow the tutorial?
umbral saffron
not yet
spring pond
you probably should
umbral saffron
im going to but i have some things to do first
crystal tundra
i gotta tell u, if u import the whole of PyQt5 ur program is gonna be massive
last project i did with it, i left in unused imports
and the windows version was 35mb
the linux version was 110mb
so u really wanna be careful about only including the smallest amount of stuff possible

How can I allocate memory to smart pointers and then store them inside a class without them going out of scope as soon as the function used to create the smart pointers is done. I need to store them inside my class but they are deleted as soon as the createsmartpointer functions is done
spring pond
list indexes shouldnt be nested
wispy anchor
I figured it out
list3 = [1,2,[3,4,'hello']]
list3[2][2] = "goodbye"
print(list3)
im dumb

@nocturne galleon well im assuming this is c++, so i give my advice: in ur class definition: ```cpp
class Foo {
private:
std::unique_ptr<int> ptr;
public:
void makePtr(int& number) {
this->ptr = std::make_unique<int>(number);
}
};
just make the function to create the smart pointer a method
rather than a global function

how do i access my linux terminal from a website, or make buttons to run series of commands on a website
spring pond
are you saying that you want to access a terminal-like environment from a website?
if so, you'd have to use something like https://www.npmjs.com/package/node-ssh
umbral saffron
bruh
i installed google
on python
it shows it
but on the actual code it doesnt work
wispy anchor
I am so close to having this figured out I just gotta figure out a way to remove everything thats not an alphabetical letter. Or remove anything from the list before a (since they are all listed before the a)
umbral saffron
what does it do?
cinder kraken
Not an expert on this, but wouldn't regex do that in a one liner?
umbral saffron
why can i not import google
like I already imported it
it doesnt work in the code tho
wispy anchor
@cinder kraken I do not know Regex but yes I do see regex suggestions when I google to remove the characters. I assume you don't mean it can do the whole thing?
@umbral saffron are you trolling?
wispy anchor
I don't know what you are trying to do but judging by that red line there is no standard libary for python called google
umbral saffron
there is tho
wispy anchor
Well the line means the module is not there
umbral saffron
oh
wispy anchor
but idk the module so cant help you
umbral saffron
ok
wispy anchor
I think you might be getting ahead of yourself
like if the thing i linked does not really make sense to you
its really basic
you might wanna still be learning the fundementals
Like what are the different data types, comparisons, lists, loops etc etc
Arithmetic operators
umbral saffron
ye probably

A pangram is a sentence that contains every single letter of the alphabet at least once. For example, the sentence "The quick brown fox jumps over the lazy dog" is a pangram, because it uses the letters A-Z at least once (case is irrelevant).
Given a string, detect whether or not it is a pangram. Return True if it is, False if not. Ignore numbers and punctuation.
was the assignment btw on Code Wars

@spring pond
import wolframalpha
import PyQt5
from PyQt5 import QtWidgets
from PyQt5.Widgets import QApplication, QMainwindow
import sys
def window():
app = QApplication(sys.argv)
win = QMainwindow()
win.setGeometry(200, 200, 300, 300)
client_wolf = wolframalpha.Client("API")
result_wolf = client_wolf.query("question goes here")
print((next(result_wolf.results).text))
def query_wolframalpha(text):
client_wolf = wolframalpha.Client("API")
result = client_wolf.query(text)
return next(result.results).text```
why doesnt this work (i removed the APIs so thats not it)well you aren't calling window()
spring pond
whats the error
spring pond
you need to use from Pyqt5.QtWidgets import ...
spring pond
no you didnt
umbral saffron
does it need to be lowercase?
spring pond
from PyQt5 import QtWidgets
from PyQt5.Widgets import QApplication, QMainwindow
this is not correct
this is
from PyQt5.QtWidgets import QApplication, QMainwindow
just that line
umbral saffron
ok
so that fixed one of the issues
WAIT
i got it to work
thanks
but trying to add a label breaks it...
umbral saffron
yes
from PyQt5.QtWidgets import QApplication, QMainWindow, QLabel```but its grey
like I havent used it yet
label = QtWidgets.QLabel(win)```but i did
spring pond
is it not showing up or whats happening
umbral saffron
label = QtWidgets.QLabel(win)
AttributeError: 'NoneType' object has no attribute 'QLabel'```oh
umbral saffron
ye
spring pond
nah youre learning

How do I store an fluctuating amount of node pointers that are of type unique_ptr<node> inside the Node class? Every time I create node class I'll tell it the amount of children it will have. Im having problems storing the smart pointer
umbral saffron
why does it say that I have an invalid syntax?
import PyQt5
from PyQt5.QtWidgets import QApplication, QMainWindow, QLabel, QPushButton
import sys
from PyQt5.uic.properties import QtWidgets
class MyWindow(QMainWindow)
def __init__(self):
super(MyWindow, self).__init__()
win = QMainWindow ()
win.setGeometry (200, 200, 300, 300)
def initUI(self):
self.label = QLabel (win)
self.label.setText ("Attempt one PyQt5")
self.label.move (50, 50)
self.b1 = QPushButton(win)
self.b1.setText ("Click this")
self.b1.clicked.connect (clicked)
def clicked(self):
self.label.setText("you pressed the button")
def clicked():
print("clicked")
def window():
app = QApplication(sys.argv)
win = MyWindow()
win.show()
sys.exit(app.exec_())
window()```kinda
hollow basalt
this is a common mistake, don't worry
I think your thought process is
win = QMainWindow ()
Would make it a class variable?
umbral saffron
yes
hollow basalt
that doesn't work in python
you need to use the self keyword
def __init__(self):
super(MyWindow, self).__init__()
self.win = QMainWindow ()
self.win.setGeometry (200, 200, 300, 300)
everytime you need to use this variable use self
e.g.
def initUI(self):
self.label = QLabel (self.win)
self.label.setText ("Attempt one PyQt5")
self.label.move (50, 50)
@umbral saffron 
umbral saffron
ohhhhhh ok
hollow basalt
class variable exists btw, but you're calling a method
umbral saffron
so instead of win it would be self.win
hollow basalt
yes
umbral saffron
ok
umbral saffron
it still says MyWindow(QMainWindow) is not a valid syntax
hollow basalt
did you copy pasted it line by line?
cause you need the semi-colon
class MyWindow(QMainWindow):
little by little
umbral saffron
thanks
umbral saffron
ok
umbral saffron
class MyWindow(QMainWindow):
def __init__(self):
super(MyWindow, self).__init__()
self.win = QMainWindow ()
self.win.setGeometry (200, 200, 300, 300)
def initUI(self):
self.label = QLabel (win)
self.label.setText ("Attempt one PyQt5")
self.label.move (50, 50)
self.b1 = QPushButton(win)
self.b1.setText ("Click this")
self.b1.clicked.connect (clicked)
def clicked(self):
self.label.setText("you pressed the button")
def clicked():
print("clicked")
def window():
app = QApplication(sys.argv)
win = MyWindow()
win.show()
sys.exit(app.exec_())
window()```I thought you used self.win
e.g.
self.label = QLabel (self.win)
self.b1 = QPushButton(self.win)
I dunno what tutorial you are using, but you missed a copy paste in the init function (constructor)
just a hint lel, find it out yourself
umbral saffron
wait wait wait
ur right
i didnt do the self. thing for all of them
thats why it didnt work
wait what
hollow basalt
still doesn't work after you used the self ?
hollow basalt
can you screenshot
hollow basalt
ah yes
i said the hint
you missed a copy paste in the init function (constructor)
want to help you, but also want you to learn
finite nest
Can this channel be used for porting purposes also?
hollow basalt
@umbral saffron i guess I would tell you the answer now
you didin't called the initUI
so you declared it, but didn't used it
umbral saffron
how learning am I
hollow basalt
very
hollow basalt
i mean you just asked for porting
most people don't know about porting
i'd say you're smarter than me @finite nest

I only successfully ported ubuntu touch twice with literally no knowledge how. nor do i remember half of it.
