Saying "functional languages" isn't enough since they are a subset of both POO and procedural programming.

Anyone have recommendations for must-read books for beginners? Very new, and looking for something to get me started.

>>59791061
You do understand that functional and OOP languages are entirely different and serve their own unique purposes. Stating that one is superior to the other is silly and lacks a deep understanding of the real purpose of a functional language.
Besides that, functional programmers are a minority in programmers and software space so of course you're going to be called a special snowflake.

>You do understand that functional and OOP languages are entirely different
Only a retard can make such claims considering one is a subset of the other.

You calling me a nerd, faggot?

"The entire point of programming is automation. The question that immediately comes to mind after you learn this fact is - why not program a computer to program itself? Macros are a simple mechanism for generating code, in other words, automating programming. Unless your system includes a better mechanism for automating programming (so far, I have not seen any such mechanisms), _not_ having macros means that you basically don't understand _why_ you are writing code.

This is why it is not surprising that most software sucks - a lot of programmers only have a very shallow understanding of why they are programming. Even many hackers just hack because it's fun. So is masturbation.

This is also the reason why functional programming languages ignore macros. The people behind them are not interested in programming automation. Wadler created ML to help automate proofs. The Haskell gang is primarily interested in advancing applied type theory.

Which brings me to my last point: as you probably know, the reputation of the functional programming people as intelligent is not baseless. You don't need macros if you know what you are doing (your domain), and your system is already targeted at your domain. Adding macros to ML will have no impact on its usefulness for building theorem provers. You can't make APL or Matlab better languages for working with arrays by adding macros. But as soon as you need to express new domain concepts in a language that does not natively support them, macros become essential to maintaining good, concise code. This IMO is the largest missing piece in most projects based around domain-driven design."

#define assertmf(cond, kill, msg, ...) if(!(cond)) { log_errorf(msg, __VA_ARGS__); if(kill) { assert(cond); exit(EXIT_FAILURE); }}

Any function that can fail should return a bool and it should be checked by the caller that way if it's not a error that kills the entire program caller functions can adjust appropriately to a failed function.

The reason I love C over Java or C++ is, C doens't have huge library.
Every now and then C#, C++ or Java would add tons of libraries. Using libraries make development faster but also makes you very dump.

Eh, for pretty much all of my undergrad years, I didn't work with other people at all. Just go to class, then go home and do homework there. Having to work around others is primarily because we have a lab dedicated graduate research, and we've been told "we really want you to be using the lab." Also because I no longer have a Windows machine, and part of my research has involved Windows-based malware.

It's not really an autism thing, so much as it's a chatter thing. I don't split focus that well with programming. For me, an ideal situation is total silence, no sources of light except for that of my computer screen, and laying horizontally. Total sensory deprivation so that the only thing in front of me is my work. Incidentally, when I finally become a professor, I am going to relish having a door I can just leave locked when it is not office hours.

Factually wrong. The only ugly parts of C++ are template abuse that arises from abusing Boost for example, but that's as dumb as criticizing C for the insane function pointers or Haskell for the quadruple nested recursive calls.

>>59792783
Is there no text mode binary mode like in C to translate '\n' into the correct string?

>>59792790
Does the standard define "\n" to always print the correct thing (i.e. transforming it to "\r\n" on Windows)? Doesn't sound like a clever thing to do.

>>59792805
I don't see why you think std::endl would do anything useful. It doesn't adapt to the platform beyond what a \n does. The Cpp committee is stupid and they do things to confuse people into thinking they're improving on C. Get that in your head already.
It's just a \n and a flush. That's it. Practically everyone knows this now. If you wanted a flush you probably don't want it to be hidden in what just looks like a newline.

I don't see how it's unreasonable to expect that std::endl would depend on the compiler implementation to print \n on unixoid systems and \r\n on Windows systems.

That's what 'binary' vs 'text' is for when opening files.

>>59792917
I don't know why they did it for a fact. But I speculate it's to sow confusion about probability.

Indeed.

You can also view random binary files and let some program interpret it as text.

>>59792977
>ascii is encoding isn't it?
The result is still some binary data.

>>59792991
My point is that making a distinction between "text" and "binary data" is stupid. Introduce good functions that take care of that and don't fucking mess with data written to a file. Because it seems you'd have to write all your """text""" files as """binary""" if you want the contents to be the same on all platforms.

>>59793015
Did your post have a point? I didn't say that.
>>59793017
You're being very short sighted.

>>59793024
>Because it seems you'd have to write all your """text""" files as """binary""" if you want the contents to be the same on all platforms.
No. The content of a text file is lines (without eol). The content of a binary file is the bytes. If you never confuse you'll have no problem. Wanting the same SHA1 for text files is stupid, it has no semantics.

>>59793024
>My point is that making a distinction between "text" and "binary data" is stupid. Introduce good functions that take care of that and don't fucking mess with data written to a file.
Then your issue isn't about distinguishing text vs binary data, but about having explicit functions vs a global mode which switches internal conversion functions on and off, it's a tradeoff between terseness and hidden assumptions vs explicitness and verbosity.

>>59793024
Anon the reason there is text mode and binary mode is because of how there's different platforms. Text mode is for reading and writing text in a consistent format that's supposed by the platform. Binary is for when you wish to control that yourself. As I said you can think of it as interpreted mode and literal mode. Binary mode is literal because it doesn't change what you output. Text mode adapts to the platform (\r\n on Windows instead of just \n for instance).

I agree there's plenty of in-software binary vs format confusion that's dumb but we're kinda going off topic here right?

If you want to output different information to a page in real time, you pretty much have to use javascript.
Although your first post sounds more like you are trying to reinvent something like PHP or Perl.

>>59794365
Do you mean that you press the Pokeball /on the local website/ and have it go back to the C++ program?
Because in that case you're looking for a web server/web backend script instead.

Check out Flask (http://flask.pocoo.org/), you can do what you want to do in like 20 lines of code or less.

>>59794388
the first post was just trying to get the basics of interfacing different programming languages. So should I be working on Javascript instead of C++, or do I send result from C++ to Javascript program and get API.

In my class we used Python to parse data from webpages and printed out the results on a Linux Terminal (like searching for time on webpage and printing it out).

Difference here is that I'm starting with C++ and want to send this result to python/javascript to find the info I want from the websites?

>>59794433
Well, something like this (pretty barebones with no error checking and stuff):

from flask import Flask, render_template_string
from random import randint
import requests

app = Flask(__name__)

POKEMONS = ['Bulbasaur', 'Charmander', 'idk']
API_ENDPOINT = 'https://whatever/{}'

@app.route('/')
def route_index():
    req = requests.get(API_ENDPOINT.format(
        POKEMONS[randint(0, len(POKEMONS - 1))]
    ))
    info = req.json()

    return render_template_string(
        '<img src="{% image %}">'
        '<a href="/catch/{% name %}'
    , image = info.whatever, name = info.whatever)

@app.route('/catch/<string:name>')
    status = 'You failed to catch the Pokemon.'
    if randint(1, 2) == 1:
        status = 'You caught the Pokemon!'

    return render_template_string(
        '<strong>{% status %}</strong>'
    , status = status)

if __name__ == '__main__':
    app.run()

>>59794433
When pokeball is pressed, the C++ Program then determines probability of it being caught, and will then print if it was successful or not. I'll look into flask right now

Just to be absolutely clear, are you actually making something that outputs to a page that is served to somebody via the interweb, or are you just talking about accessing and scraping pages and using that information locally within your executable?
I mean, you said "Print this out to local Web Page" but I'm not seeing how that ties in, and your requirements are a lot more lenient if you aren't serving something.

Anyone here has any experience creating plugins for cordova using plugman?

>>59794780
the only internet involved is going to the API to get the imageURL. This one in particular.

https://api.pokemontcg.io/v1/cards?page=5&pageSize=1000

So I look for the string "Charizard" and print out its corresponding URL to my local webpage, not something actually on the internet, but rather looks like

file:///C:/Users/Pokemon.html

From there, I press the pokeball that is also on the webpage, which will then go back to some program (Back to C++ one?) that calculates probability of catching and then printing if it was successful or not on the terminal.

>>59794778
It calls malloc eventually, anyway.
