[Lua]Brainf*ck Interpreter
« on: September 28, 2011, 08:53:24 pm »
So I'm starting to learn brainf*ck. So I decided it would be fun to create a quick brainf*ck interpreter in Lua for use on the nspire. :D

I am 99% finished except that the input and output don't work yet. So here's the code if anyone can spot where I'm going wrong. :)

http://pastebin.com/8akS6P9H

Spoiler For Spoiler:
I will also be making a whitespace IDE after this ;D

Thanks![/s]

I have finished the first working version of this program! XD I've attached the source as well as the exe.

Usage is as follows: when you start, you can immediately start writing bf code. You can only use the characters ,.<>[]+- though. Let me know if you want to change that.

Currently there is no word wrap. I need ideas on how to do that. Backspace will delete the last character and arrow keys do nothing.

Press enter to execute and kill the program.

After this will come a whitespace IDE as well.  :w00t:

This project is still incomplete though, and will be for a while.

Late last night, Quebec was invaded by a group calling themselves, "Omnimaga". Not much is known about these mysterious people except that they all carried calculators of some kind and they all seemed to converge on one house in particular. Experts estimate that the combined power of their fabled calculators is greater than all the worlds super computers put together. The group seems to be holding out in the home of a certain DJ_O, who the Omnimagians claim to be their founder. Such power has put the world at a standstill with everyone waiting to see what the Omnimagians will do...

Wait... This just in, the Omnimagians have sent the UN a list of demands that must be met or else the world will be "submitted to the wrath of Netham45's Lobster Army". Such demands include >9001 crates of peanuts, sacrificial blue lobsters, and a wide assortment of cherry flavored items. With such computing power stored in the hands of such people, we can only hope these demands are met.

In the wake of these events, we can only ask, Why? Why do these people make these demands, what caused them to gather, and what are their future plans...

I updated the pastebin code.

http://pastebin.com/5jM9gySm

I still can't figure out what's going wrong. I think output's working but the input is not. How would I be able to make the program pause and wait for an input?

Also, it displays but it flickers. Why is this? I think it's because I'm refreshing the screen a lot or it's trying to display two strings in the same area.

I'm going to have a special mode to actually see the characters with that IDE.

To any who haven't seen the first post,

Well, I done and goofed. I realized yesterday that the nspire doesn't have the "[" and "]" easily accessible as separate characters. So I made it so "()" = "[]". :)

I also added in linebreaks via the return key (Not the enter key).

I also removed some redundancies and hopefully I managed to fix a HUGE memory leak.  ;D

Congrats !
I don't know anything about brainf*ck, but I can figure that this was not easy to do...

It actually wasn't too difficult. The worst part was trying to figure out why input wasn't working at first, really. :)

Whitespace might be a little trickier because it's a little more complex than BF. I also have to figure out a way to get tabs. :S
