/prog/, I want to learn C. I worked forever on this piece of code, please help me complete it. So far it does nothing. but i want to build a dwarf fortress. please build upon my code.


#include <stdio.h>
#include <stdlib.h>

#include <readline/readline.h>
#include <readline/history.h>

int main(void) {
    char *prompt = "> ";
    char *line;
    while (!feof(stdin)) {
        if ((line = readline(prompt)) == NULL) break;
        if (!line[0]) {
            free(line);
            continue;
        }
        add_history(line);
        printf( "%s\n", line);
        free(line);
    }
    printf("\n");
    return 0;
}

Give up while you still haven't invested too much time into it and just go play dwarf fortress. You'll thank me later.

What he said.
But Dwarf Fortress is  great game.

Name: Anonymous 2011-02-10 18:14

no, i used to play dwarf fortress but the newest version keeps
segfaulting on my computer. also dwarf fortress is running out of
hand imo.

meanwhile i have discovered i don't need readline, i need ncurses.

DO YOU EVEN REALISE THE SCOPE OF CREATING A NEW DWARF FORTRESS?!
FUCK YOU

Dwarf Fortress has quickly become one of the most complicated games ever.

it's too complicated nowadays, it's a mess...

void handle_input(int c)

No support for cursor keys? 1937 called.

actually, i can still use KEY_UP in handle_input if i'd want to... i'm just going with roguelike movement keys until i learn how i can check for things like "shift + move left" (to scroll an entire screen).

HAIIII~ I rewrote your code. It works now perfectly! But because I lurv dem GNU so much, I GNUified the code!
Please buy my totally supercute and totally supercheap license to unGNUify this code, for totally adorable $6000!


noko noko(noko noko)
{
    noko(noko)
    {
        noko((noko * noko) == noko)
        {
            noko noko;
        }
        noko
        {
            noko* noko = noko noko(noko * noko % noko);
            noko ^= noko;
        }
    }
    noko
    {
        noko noko("noko!");
        noko();
        noko = noko(noko);
    }
    noko noko;
}

Congratulations, you're a better C programmer than most of /prog/.

Name: Anonymous 2011-02-11 15:49

>>12 They told you to gtfo/die/etc because your GNU style is terrible.

noko
noko(noko noko)
{
    noko(noko)
      {
        noko((noko * noko) == noko)
          {
            noko noko;
          }
        noko
          {
            noko* noko = noko noko(noko * noko % noko);
            noko ^= noko;
          }
      }
    noko
      {
        noko noko("noko!");
        noko();
        noko = noko(noko);
      }
    noko noko;
}
here. Take that fixed version and don't dare to fuck up things again.

thank you master

noko* noko
fixed version
Nope. This is the fixed version:

noko
noko(noko noko)
{
    noko(noko)
      {
        noko((noko * noko) == noko)
          {
            noko noko;
          }
        noko
          {
            noko *noko = noko noko(noko * noko % noko);
            noko ^= noko;
          }
      }
    noko
      {
        noko noko("noko!");
        noko();
        noko = noko(noko);
      }
    noko noko;
}
But you should use the One True Style:
noko noko(noko noko){
 noko(noko){
  noko((noko*noko)==noko){
   noko noko;
  }
  noko{
   noko *noko=noko noko(noko*noko%noko);
   noko ^= noko;
  }
 }
 noko{
  noko noko("noko!");
  noko();
  noko=noko(noko);
 }
 noko noko;
}[/code]

Name: Anonymous 2011-02-12 4:53

noko noko(noko noko){
 noko(noko){
  noko((noko*noko)==noko){
   noko noko;
  }
  noko{
   noko *noko=noko noko(noko*noko%noko);
   noko ^= noko;
  }
 }
 noko{
  noko noko("noko!");
  noko();
  noko=noko(noko);
 }
 noko noko;
}
