Longest program you have written?

[JVallius]

Naku The Cat has about 3k lines. Though during the last weeks before release my code started to get very messy. I guess I could shave line count a lot if I ever happen to bother.

Once upon a time on my Vic-20 (with 16K RAM expansion) I wrote a program that took 19 seconds to list. It was a Logo interpreter (with a smattering of machine code to draw hires lines, which I cribbed from a book). And who said Commodore BASIC was rubbish

Thats what I call old school.

Well, it was about 1981 or so.

The longest code I wrote was in my old job, while porting a very old ERP to something "more visual". Around 200K lines or so, with the worst and more obfuscated language that exists in the universe

And as the longest personal work, there where 2 and I'm not sure which where longer (around 20K lines). One was something like a Windows OS I wrote more than 20 years back in C, and the other a shooter for the Nintendo GameBoy Color.

LOC means nothing. My current work-project is 105k of java, xml, jelly and groovy...

A Hello World program!!!!

A Hello World program!!!! 

Ha, an interesting project would to write as many lines of code, outputting "hello world".

You'd end up with something similar to FizzBuzzEnterpriseEdition.

Nice, I'm gonna use this

I can't stop laughing! I also can't stop crying, as I've seen code like this at my corporate internship

200K and counting...

Yeah, LOC is peanuts, it is all about how fast you can get things to work.

1   2   3   4   5   6   7   8   9   10

for(int i = 1; i < 101; i++){      if(i%15 == 0)          System.out.println("FizzBuzz");      else if(i%3 == 0)          System.out.println("Fizz");      else if(i%5 == 0)          System.out.println("Buzz");      else          System.out.println(i); }

I can't concentrate with all that Fizz Buzz...

1   2   3   4   5

for(int i=1;i<101;i++) {       int a=((528>>i%15-1)&1)*4;       int b=((-2128340926>>(i%15)*2)&3)*4;       System.out.println("FizzBuzz".substring(a,b)+(a==b?i:""));    }

Guardian is currently 9084 (excluding my personal libraries. Personal libraries included I get 14451 LOC)
The archived 'Guardian II' was about 15233 lines. Just as well I rewrote it.

Paint.JAVA is currently ~13000 lines, although some amount of those were written by Longor1996, BurntPizza, and some other contributors.

My voxel engine is a mere 2481 lines.

My Ludum Dare entries are all around 2500 LOC, with the exception of the 7dRTS which was 6069. (Which you'd expect from a longer competition)

Of course, a fair number of those lines aren't technically code.

[StumpyStrust]

hmmm...almost all of the stuff I have posted would be in the range of 500-2k. I try and be clean with code...try. 

[Longor1996]

My current project is rather small then with its 10'272 lines of code.
That is, exluding the libraries I am using (LWJGL, KryoNET, EventBus).

At least according to SourceMonitor...

All that just for a Voxel-Engine!

I would say the longest I've written so far is my RTS game(its not even finished yet).
It's currently:
5515+
