I have learned that hacking something together instead of doing it properly never pays off in the end.

Is there a better way to write this without it looking so retarded and repetitive?

var xml = fs.readFileSync('./metadata.opf', 'utf8');
var final = {};

// Grabbing important meta from opf file.
if (xml.match("opf:role=\"aut\">(.*)<\/dc:creator>")){
    final.author = xml.match("opf:role=\"aut\">(.*)<\/dc:creator>")[1];
} else { throw (new Error("no author"));}
if (xml.match("<dc:publisher>(.*)<\/dc:publisher>")){
    final.publisher = xml.match("<dc:publisher>(.*)<\/dc:publisher>")[1];
} else { final.publisher = "unknown";}
if (xml.match("<dc:date>(.*)T")){
    final.date = xml.match("<dc:date>(.*)T")[1];
} else { final.date = "unknown";}
if (xml.match("<dc:title>(.*)<\/dc:title>")){
    final.title = xml.match("<dc:title>(.*)<\/dc:title>")[1];
} else { throw (new Error("no title"));}
if (xml.match("<dc:identifier opf:scheme=\"ISBN\">(.*)<\/dc:identifier>")){
    final.isbn = xml.match("<dc:identifier opf:scheme=\"ISBN\">(.*)<\/dc:identifier>")[1];
} else {final.isbn = "no isbn";}

tfw your boss insists that you can catch exceptions thrown by the delete operator in C++ when their signatures are marked noexcept

>>57989394
Stop trying to parse XML with regular expressions, you fucking idiot.

>>57989394
1. Pull your regexes out into variables.
2. Create a class to represent a regex, the attribute to set if a match is found, and the action to perform if no match is found (tip: make it a function). Make a list of instances of this class and iterate through it.

Working on this problem for my Python class, but my program makes no substitutions to the txt file. Any help would be appreciated.

try:
    myfile = open("bieber_baby.txt", "r")

except:

    print("Sorry, the file doesn't exist")

else:
    print("Total words in thesaurus: ", total_words)
    lyrics = myfile.read()

    #remove punctuation from the file
    
    lyrics_no = ""
    for word in lyrics:
        if word.isalpha():
            lyrics_no += word

        elif word.isspace():
            lyrics_no += word

    #split by word
    word_lyrics = lyrics_no.split("\n")

    #ask the user to enter a probability of changing lyrics

    chance = float(input("Enter a % chance to change a word: "))

    #Blank list of altered lyrics
    audio = ("")
    
    #examine each line
    for line in word_lyrics:

        #split the line to make into string of words
        words = line.split(" ")

        #make a program to decide whether to alter words or not
        for c in words:

            swapnum = random.randint(1,101)

            #Check if the words should change by probability and by existing in thesaurus 
            if (swapnum <= int(chance)) and (c in dictionary):

                #choosing a synonym word from the list
                random_position = random.randint(0,len(dictionary[c])-1)

            #if word is not found in dictionary, add the original word.

2012 says hi

Anyone have a link to a good tutorial to developing on iOS, including platform to use (I currently have XCode -- not sure if that's a good one to use)? I'm on a Mac, if that helps.

I found this, but not sure if it's a good tutorial
https://developer.apple.com/library/content/referencelibrary/GettingStarted/DevelopiOSAppsSwift/
(I also don't know Swift.) I'd rather develop on Android since I already know Java, but everyone I know has an iPhone, and I can't get word-of-mouth going as well (on an immediate, personal level) on Android, even if the latter has a larger user base.

>>57989458
You have to actually write to the file.

>>57989482

>>57989466

No.

>>57989515
No, you just have to read the file and then print out an edited version. How you do that is up to you.

Repost:Are there any C# + F# programmers here? I'm primarily (read: entirely) a Lisp developer for the past couple of years but I'm really starting to feel some friction from lack of libraries and lack of good compiler/editor integration*.

I'd like to learn F#, but do I need to learn C# first? How good is the interop between them? Apparently if your program uses a GUI you still need to use C# for it. Will I be able to just whip up a straightforward GUI and do all of my programming in F#? I haven't found any guides or tutorials (or even many people) aimed towards people who are in my particular situation of being more comfortable with functional programming and dynamic typing than their reverse.

>>57989529
>>57989532
The code I've written just strips out punctuation and prints the text as one whole block without line breaks or synonyms. Any suggestions?

>>57989578
Fire up a debugger and step through your code to see what's happening, and compare it to your expectations.

>>57989570
Not a .NET programmer but I imagine there's lots more .NET library tutorials available for C# than for F# so it probably pays to be able to read C# a little. Wouldn't spend ages learning it though.

>>57989423

Try focusing on just doing a single word or a single line as a proof-of-concept, perhaps with a string you've made up yourself. I don't feel like looking at your code or spoonfeeding you, but you're probably doing something wrong with an if-statement. Probably a logical error.

Functional programming is great and all, but near impossible to debug using conventional means, especially when you're mucking about with continuations, endomorphisms, etc.

>>57989762
I've used it successfully with phrases I created through an input command. But it doesn't seem to work when I use a text file. I just don't see why it's not working.

True, true. I was actually surprising myself when coding drunk a couple weeks ago. Almost too drunk to walk but was writing great code. I had to go back and re-read it sober to figure out what I did.

>>57989958
>looks better don't it?
Not really

>is probably more readable as well
No again

>>57989900
Continuations aren't used in regular programming. They're deliberately intended to use in a very, very low-level in limited situations in order to construct a new control-flow for a specific operation. It's like a programmable goto. Use delimited continuations to help avoid manually debugging unwind.

You use them with the same restrictions and care that you would when modifying the control flow of any other programming language. Of course, most other programming languages don't allow you to modify control flow outside of the already-given syntactical structures like for, goto, etc. to stop you from shooting yourself in the foot.

>>57989922
At each step, print out whatever data is important for that step, doing this one step at a time, making sure each step is done correctly. For instance, make sure you're adding the right string/transformation to your list. Printing shit out is the easiest way to make sure individual steps are functioning properly.

>>57990043
If he were using a real language he could use a debugger instead of having to put print statements everywhere in his code.

>>57989900
But there's absolutely nothing special about endomorphisms in programming.

I don't even really know memescript, so I had to look most of this shit up, but here is a cheeky way of doing it:

xml = "<dc:publisher>asdf</dc:publisher>"

var call = (fn) => typeof fn == "function" ? fn() : fn
var extract = (re, def) => (xml.match(re) || {1: call(def)})[1]

var final = {}

final.author = extract(/<dc:publisher>(.*)<\/dc:publisher>/, () => {throw "no author"})
final.publisher = extract(/<dc:publisher>(.*)<\/dc:publisher>/, "unknown")
final.date = extract(/<dc:publisher>(.*)<\/dc:publisher>/, "unknown")
final.title = extract(/<dc:publisher>(.*)<\/dc:publisher>/, () => {throw "no title"})
final.ibsn = extract(/<dc:publisher>(.*)<\/dc:publisher>/, "no ibsn")

console.log(final)

Ignore that all of the regexs are the same, I just couldn't be bothered writing a test xml string to match all of that shit.
Obviously if you were going to use this, you would change them.

>>57991922
I think you're retarded. Sorry.
Save it and run it in your terminal.
Example:

$ ./myscript

So in Java, if x = 5 and y = 7:

System.out.println(x + ' ' + y); <-- prints out "44"
System.out.println(x + " " + y); <-- prints out "5 7"

Why the fuck does the first one print out 44? How did it get 44?

>>57991992
Single quotes indicate a char, so in your first statement, that char is being implicitly converted to an int and added to x and y
It's 44 because the space char has a value of 32

Am I better off using an IDE (CLion) for C++ compared to using Vim or any other text editor?

For C I wouldn't need to use an IDE since Vim does the job perfectly well, but C++ I don't really know.

what is the best way to format functions with loads of arguments?

>>57992904
If you're passing lots of relevant variables together, why not keep it in a struct and pass just a struct pointer?

File: TLPI-front-cover.png (183KB, 454x600px) Image search: [Google]

183KB, 454x600px

Reading the following

>>57992941
This binds data together in an unnecessary way. See: OOP

>>57992952
Are you retarded?
The alternative is function signatures with 20+ variables for anything non-trivial.

>>57992904
I just make sure to indent it 2 tabs so that it doesn't clash with the base indentation of the function's body.

>>57992962
>20+ variables

the most wayland has is around 6, which is what I'm using here
>>57992904

it's the names that make the functions run off the page.
There is no way of getting away with long arguments, that's why I asked the best way to format arguments

>>57992962
If data should be bound together, structs should be used.
Not always should data be bound together. Should all functions just take 1 parameter, a pointer to struct functionname_arg_struct?

>>57992998
>If data should be bound together, structs should be used.

if you are dealing with a server, that means you have to copy the--masive--struct for every message

>>57992985
I recommend K&R style.

void shell_surface_configure(a, b, c, d, e)
void *a;
struct wl_shell_surface *b;
uint32_t c;
int32_t d;
int32_t e;
{
     /* ~~~ */

>>57993016

Copying massive structs is exactly the same as forwarding a lot of arguments... which can be pretty efficient in calling conventions that utilize registers.

C++ in general is pretty awful.
It's too C and at the same time, not C enough.
They really should have cut off all compatibility with C over 20 years ago.

In 20 years, C managed to entrench itself as the low-level lingua franca and the use cases for pure C++ have quickly dried up to Game Dev and nothing else.
