Brainfuck guro flash game how to#
Lets start with some examples of how to program in brainfuck. Loops may be nested as many times as you want. And the memory pointer starts out on the very left most memory Characters besides the 8 operators should be con-Īll memory blocks on the "array" are set to zero at the beginning of the print 1 character to the console Some rules:Īny arbitrary character besides the 8 listed above should be ignored by theĬompiler or interpretor. ] = if block currently pointed to's value is not zero, jump back to [, = like c getchar(). [ = like c while(cur_block_value != 0) loop. + = increases value stored at the block pointed to by the memory pointer - = decreases value stored at the block pointed to by the memory pointer < = decreases memory pointer, or moves the pointer to the left 1 block. > = increases memory pointer, or moves the pointer to the right 1 block. Let me first present to you the 8 operators available to us. Within this array, you can increase the memory pointer, increase the value at the memory pointer, etc. The array size is actually dependent upon the implementation used in the compiler or interpretor, but standard brainfuck states 30,000. Basically you are given an array of 30,000 1byte memory blocks. The idea behind brainfuck is memory manipulation. I promise you, if you take the time to sit and write a program in brainfuck for an hour or five, you will definitely see why it deserves its name. Lastly, i would recommend having no life and lots of time on your hands to actually want to sit and write programs in this amazingly inefficient language. It will help you figure out the Greatest Common Factors for use in incrementing a memory block quickly. Next on the items is would be a calculator. Next, i would suggest an ASCII chart with all the ASCII chars and their decimal equivalent value.
You'll find all those in the last section of this tutorial.
Also i have included the source for the worlds smallest Compiler (171 bytes) written in x86 assembly by Brian Raiter. If you don't quite know how to write one, I have included the source to a Brainfuck-to-C interpreter that I wrote in C as well as one that I wrote in BrainFuck itself. An experienced programmer could easily write one quite quickly after reading this. To write programs in brainfuck, i would suggest you get a few things first.įirst of all you will need an interpreter or a compiler. you are capable of writing almost any program you can think of. The language only consists of 8 operators, yet with the 8 operators, +. And, yes, there are quite a few tutorials that you will find on google about the language and how to program in it, but i am writing this one as most of them that you will find seem to only cover just the basics of using the operators.īrainfuck, language itself, is a Turing-complete language created by Urban Müller.
