On a sidenote, I hope someone gets 23. We need one for 8chan.

I need to write a list container today, but I will roll for a new exercise. Fully expect 84 on account of /g/ being slow.

Cool anon. I don't do web stuff but lately I've been picking up javascript for firefox extensions.

<button> is html tag and namesFunction() is the callback when clicked?

Here is my shitty paint program from >>3584

It's not yet fully implemented and has some errors (not a 1-to-1 correspondence between what is shown and what is saved, keeping track of all those points is slow eventually and isn't the best approach. Group paint isn't functional yet. Also, not the best OOP...)

I know I didn't roll it, but I'm new to Java and this thread inspired me to write a program that counts the number of letters, words, and sentences in your input.

Tell me if I'm doing something dumb or unneeded in doing this

package countwordsinastring;

import java.util.Scanner;

public class Main {

    public static void main(String[] args) {
        System.out.println("(Type 'EXIT' to exit)");
        System.out.println("Enter complete sentences:");
        boolean stillRunning = true;

        while(stillRunning){
        Scanner input = new Scanner(System.in);
        String userInput = input.nextLine();

        if(!userInput.equals("EXIT")){
        int sentences = 0 ;
        int words = 1 ;
        int letters = 0;

            System.out.println();

            int i = 0;
        char[] inputArr = new char[userInput.length() + 2];

        for (i = 0; i < userInput.length(); i++) {
            inputArr[i] = userInput.charAt(i);

            if(!Character.isLetter(inputArr[i])){
            switch (inputArr[i]) {
                case ' ':
                    words++;
                    break;
                case '.':
                    sentences++;
                    break;
                case '!':
                    sentences++;
                    break;
                default:
            }
            }else{
                letters++;
            }
        }



        if (sentences == 0) {
                sentences = 1;
            } else if(sentences > 0 && inputArr[userInput.length() - 1] != '.'
                      && inputArr[userInput.length() - 1] != '!') {
                sentences++;
            }

        System.out.println("Number of letters: " + letters);
        System.out.println("Number of words: " + words);
        System.out.println("Number of sentences: " + sentences);

            System.out.println();

        }else{
            stillRunning = false;
        }
        }
    }
}

>>3982

Focking shit

Ignore the fact that I initialize inputArr as having 2 more than userInput.length();

That was a mistake made in seeing if I could make it so that it doesn't add a sentence when it picks up on a "..." but that didn't work out so I removed it from the code

>>3982

Sorry to put so much on this thread but reading this after I posted it made me notice some formatting issues that were bugging me.

Made it more readable.

package countwordsinastring;

import java.util.Scanner;

public class Main {

    public static void main(String[] args) {
        System.out.println("(Type 'EXIT' to exit)");
        System.out.println("Enter complete sentences:");
        boolean stillRunning = true;

        while (stillRunning) {
            Scanner input = new Scanner(System.in);
            String userInput = input.nextLine();

            if (!userInput.equals("EXIT")) {
                int sentences = 0;
                int words = 1;
                int letters = 0;
                int i = 0;

                System.out.println();

                char[] inputArr = new char[userInput.length()];

                for (i = 0; i < userInput.length(); i++) {
                    inputArr[i] = userInput.charAt(i);

                    if (!Character.isLetter(inputArr[i])) {
                        switch (inputArr[i]) {
                            case ' ':
                                words++;
                                break;
                            case '.':
                                sentences++;
                                break;
                            case '!':
                                sentences++;
                                break;
                            default:
                        }
                    } else {
                        letters++;
                    }
                }



                if (sentences == 0) {
                    sentences = 1;
                } else if (sentences > 0 && 
                    inputArr[userInput.length() - 1] != '.' && 
                    inputArr[userInput.length() - 1] != '!') {
                    sentences++;
                }

                System.out.println("Number of letters: " + letters);
                System.out.println("Number of words: " + words);
                System.out.println("Number of sentences: " + sentences);

                System.out.println();

            } else {
                stillRunning = false;
            }
        }
    }
}

I'm gonna print this image out and use it as a means of inspiration for projects in Java and C++, seeing as I'm simultaneously learning those languages. I'll take these on (not necessarily in order) and learn whatever I don't know that I need to in order to complete them in my free time when I'm not learning by other means.

Wish me luck fam

require 'json'
require 'open-uri'

if ARGV.length != 2
	puts "[-] Usage: 8chan-dl <board> <threadnum>"
end

board     = ARGV[0]
threadnum = ARGV[1].to_i

threadurl = "http://8ch.net/#{board}/res/#{threadnum}.json"

thread = JSON.parse(open(threadurl).read)

title = thread['posts'][0]['sub'].gsub /[ |\/]/, '_'
puts "[+] Thread title: #{title}"

dir = "./#{title}/".gsub ' ', '_'
Dir.mkdir dir if not Dir.exists? dir

for post in thread['posts'].select{|p| p.has_key? 'ext'}
	filename = "#{post['tim']}#{post['ext']}"
	img_url = "http://media.8ch.net/#{board}/src/#{filename}"
	puts "[+] Downloading #{img_url}"
	File.open("#{dir}#{filename}", 'wb') do |file|
		file.write(open(img_url).read)
	end
end

Not the best. Has no error handling and shit but it seems to work. Also wrote a 4chan one that is very similar if you guys want that.
