Brainfuck is one of the most famous esoteric programming languages, and has inspired the creation of a host of other languages. Due to the fact that the last half of its name is often considered one of the most offensive words in the English language, it is sometimes referred to as "brainf***", "brainf*ck", "brainfsck", "b****fuck" (as a joke), "brainf**k", "branflakes", "brainoof", "brainfrick", "bf", etc. This can make it a bit difficult to search for information regarding brainfuck on the web, as the proper name might not be used at all in some articles.

Language overview

Brainfuck operates on an array of memory cells, each initially set to zero. (In the original implementation, the array was 30,000 cells long, but this may not be part of the language specification; different sizes for the array length and cell size give different variants of the language). There is a pointer, initially pointing to the first memory cell. The commands are:

Command Description
> Move the pointer to the right
< Move the pointer to the left
+ Increment the memory cell at the pointer
- Decrement the memory cell at the pointer
. Output the character signified by the cell at the pointer
, Input a character and store it in the cell at the pointer
[ Jump past the matching ] if the cell at the pointer is 0
] Jump back to the matching [ if the cell at the pointer is nonzero

All characters other than ><+-.,[] should be considered comments and ignored. But, see extensions below.

History

Brainfuck was invented by Urban Müller in 1993, in an attempt to make a language for which he could write the smallest possible compiler for the Amiga OS, version 2.0. He managed to write a 240-byte compiler. The language was inspired by FALSE, which had a 1024-byte compiler. Müller chose to name the language brainfuck (with the initial letter in lower case, although it is now often capitalised).

It is not known to what extent Müller was aware of or influenced by Böhm's language P′′ published in 1964, of which brainfuck can be considered a minor variation.

Examples

Hello, World!

This program prints out the words Hello World!:

 1 +++++ +++               Set Cell #0 to 8
 2 [
 3     >++++               Add 4 to Cell #1; this will always set Cell #1 to 4
 4     [                   as the cell will be cleared by the loop
 5         >++             Add 4*2 to Cell #2
 6         >+++            Add 4*3 to Cell #3
 7         >+++            Add 4*3 to Cell #4
 8         >+              Add 4 to Cell #5
 9         <<<<-           Decrement the loop counter in Cell #1
10     ]                   Loop till Cell #1 is zero
11     >+                  Add 1 to Cell #2
12     >+                  Add 1 to Cell #3
13     >-                  Subtract 1 from Cell #4
14     >>+                 Add 1 to Cell #6
15     [<]                 Move back to the first zero cell you find; this will
16                         be Cell #1 which was cleared by the previous loop
17     <-                  Decrement the loop Counter in Cell #0
18 ]                       Loop till Cell #0 is zero
19 
20 The result of this is:
21 Cell No :   0   1   2   3   4   5   6
22 Contents:   0   0  72 104  88  32   8
23 Pointer :   ^
24 
25 >>.                     Cell #2 has value 72 which is 'H'
26 >---.                   Subtract 3 from Cell #3 to get 101 which is 'e'
27 +++++ ++..+++.          Likewise for 'llo' from Cell #3
28 >>.                     Cell #5 is 32 for the space
29 <-.                     Subtract 1 from Cell #4 for 87 to give a 'W'
30 <.                      Cell #3 was set to 'o' from the end of 'Hello'
31 +++.----- -.----- ---.  Cell #3 for 'rl' and 'd'
32 >>+.                    Add 1 to Cell #5 gives us an exclamation point
33 >++.                    And finally a newline from Cell #6

The same program in minimised form:

++++++++[>++++[>++>+++>+++>+<<<<-]>+>+>->>+[<]<-]>>.>---.+++++++..+++.>>.<-.<.+++.------.--------.>>+.>++.

This is another program that prints out Hello, World! with correct spacing, case and punctuation:

++++++++[>++++++++<-]>++++++++.>++++++++[>++++++++++++<-]>+++++.+++++++..+++.>++++++++[>+++++<-]>++++.------------.<<<<+++++++++++++++.>>.+++.------.--------.>>+.

This is a slightly more complex variant that often triggers interpreter bugs. This uses cell values below zero and so doesn't work on score-computing interpreters.

>++++++++[-<+++++++++>]<.>>+>-[+]++>++>+++[>[->+++<<+++>]<<]>-----.>->
+++..+++.>-.<<+[>[+>+]>>]<--------------.>>.+++.------.--------.>+.>+.

Short program printing Hello, World! by primo from http://codegolf.stackexchange.com/a/68494/6691. This program needs four cells to the left of the starting point (so standard scoring would give it an adjustment of four instructions and four ticks) and requires wrapping byte sized cells.

--<-<<+[+[<+>--->->->-<<<]>]<<--.<++++++.<<-..<<.<+.>>.>>.<<<.+++.>>.>>-.<<<+.

Currently, the shortest known program printing Hello, World! is written by KSab from https://codegolf.stackexchange.com/a/163590/59487:

+[-->-[>>+>-----<<]<--<---]>-.>>>+.>>..+++[.>]<<<<.+++.------.<<-.>>>>+.

Move value

This code piece moves the value of the current cell (cell0) two cells to the right (cell2):

>>[-]<<[->>+<<]

With indentation and comments the same code looks like this:

Code:   Pseudo code:
>>      Move the pointer to cell2
[-]     Set cell2 to 0 
<<      Move the pointer back to cell0
[       While cell0 is not 0
  -       Subtract 1 from cell0
  >>      Move the pointer to cell2
  +       Add 1 to cell2
  <<      Move the pointer back to cell0
]       End while

Cat

A cat program writes its input directly to its output. As there is not a standard way to handle EOF in brainfuck, there are four versions of the program below and a non-termiating one, labelled by how they match common implementations of the interpreter. (see Implementation issues).

EOF returns 0:

,[.,]

EOF returns -1:

,+[-.,+]

No change on EOF, or EOF returns 0:

,[.[-],]

No change on EOF, or EOF returns -1:

,+[-.[-]-,+]

Never terminates:

+[>,.<]

Cell Size

This program outputs the cell width of the interpreter:

Calculate the value 256 and test if it's zero
If the interpreter errors on overflow this is where it'll happen
++++++++[>++++++++<-]>[<++++>-]
+<[>-<
    Not zero so multiply by 256 again to get 65536

        # Print "32"

Self-interpreters

Writing a self-interpreter in brainfuck is not a simple task, yet, several self-interpreters have been written throughout the years.

  • by Frans Faase - Perhaps the first one.
  • by NYYRIKKI
  • by Keymaker (from the Wayback Machine; retrieved on 17 May 2017) - Designed in the strictest 8-bit, non-wrapping, EOF = no change (EOF 0 works too) environment. The program emulates unbound cell size for cells (the program +[+] is valid and never ends) -- not really a brainfuck feature but it's there anyway -- and of course all the brainfuck programs written for the 8-bit non-wrapping environment work as supposed to. Supports infinite/unbound number of cells and nested loops.
  • by Daniel B Cristofani - The shortest; see also dbfi
  • by Clive Gifford (from the Wayback Machine; retrieved on 25 February 2021) - The fastest
  • by Adam Domurad - Interprets Brainfuck code from the input until a %, then reads remaining input as input for the interpreted program. Comments are allowed, and up to 256-depth nested loops
  • by VilgotanL - Originally written in VBF and transpiled to brainfuck, designed in 8-bit wrapping brainfuck, supports infinite nested loop depth, errors, assumes zero or no-change on eof, uses an optional ! in the input to separate the program and the input.
  • by Ørjan Johansen - Designed for achieving a calculable eigenratio.

Constructing tape instructions with Brainfuck

  • [+] or [-] can be used to set the value to 0
  • After having set it to 0 you can use repetions of + or - to get to any number you want
  • We can check if the value in the pointers location is not a specific constant, by subtracting that amount or adding 255-that amount and than using the execute if not 0 loop
  • We can execute a forever executing loop by making sure the value at the pointer won't be 0 when ] is reached.
  • If a cell only holds the values 0 and 255 (which will be interpreted as FALSE and TRUE in conditionals), we can use + which makes it become 1 and 0 (TRUE and FALSE in conditionals), so + can negate the truth values, and than to negate that code you can use -
  • For example, if the fourth item in the tape is a 0, a way of constructing an and gate between the first item and second item whose output is the third item is thru [>[>+>]]
  • A conditional that only executes one can be made by making the value the pointer is pointing to, to be 0, when it reaches ] and when you're outside the loop you can undo that to go back to where you were

Computational class

When the array is unbounded, or when the array is at least three cells long and can store unbounded values, brainfuck is Turing-complete, meaning that it is in the same computational class as universal Turing machines. This, plus its dearth of commands, makes it a canonical example of a Turing tarpit.

This can be shown in a number of ways and with various restrictions on the brainfuck program and/or interpreter. The following formulations require the array to be unbounded, but allow the value in each cell to be bounded:

Other formulations allow the array to be bounded, but require that the value in each cell be unbounded:

And still others require both the array and the value in each cell to be unbounded:

Implementation issues

Brainfuck leaves a lot of things up to the implementation to decide, such as array and cell size, and what happens when EOF is read.

Memory and wrapping

The size of the cells and the cell array varies a lot in different implementations. A usual implementation will have either 8bit or 32bit cells with 30000 cells (in the positive direction). For Turing completeness either the number of cells must be unbounded or (at least) three unbounded cells are required, the former is usually assumed.

Urban Müller's compiler used an array of 30000 cells 8bit cells, while the interpreter only allowed 100 (of 5000) to be used. As the compiler was written in assembler there is no indication as to whether the cells are to be assumed to be signed or unsigned and the overflow semantics are of the usual twos complement (or unsigned byte) wrapping form. The interpreter uses signed 8bit characters (-128 to 127 range).

Other interpreters normally use a similar layout, however, some allow cells to the left of the start position or use different allowed ranges of cell values. Some limit the cells to only positive values or other reduced ranges, others allow a larger range including 'floating point' (which would usually be in effect a 53bit integer without wrapping) or even completely unbounded integers.

Note, that it's not possible for a brainfuck program to determine if its integers are officially signed or unsigned unless they are also non-wrapping. If the cells don't wrap then the loops [-] and [+] used after an number in the opposite direction will cause a crash (ie: an exception or a hang). Most optimisers will therefore assume these sequences set a zero even with unbounded integers.

Even with wrapping cells code can be written that depends on the cell size for example Brainfuck bitwidth conversions or the code below (which only works correctly with 8bits).

+[[->]-[-<]>-]>.>>>>.<<<<-.>>-.>.<<.>>>>-.<<<<<++.>>++.

Newlines

The vast majority of brainfuck programs, following Urban Müller's original example programs, use 10 as newline on both input and output; this is also the convention used by Unix-based operating systems, including Linux and Mac OS X. Some other operating systems use different conventions for newline, and may use different conventions on input and on output, and different conventions in different programming environments (e.g. C versus assembly language). Several solutions to the problem are possible:

  • Write brainfuck programs to accept multiple linefeed conventions. (Possible, though clunky, on input; not generally possible on output.)
  • Write many versions of each brainfuck program, one for each programming environment. (Possible, but very unpleasant.)
  • Forget portability and write programs for whatever implementation you are using. (A fairly common approach. May make it hard to share programs if your interpreter doesn't use 10 as newline.)
  • Write brainfuck interpreters and compilers to translate newline to 10 on input, and 10 to newline on output, in environments where that is not already the case. (Easy and helpful, but often overlooked. Also, may break the few brainfuck programs that do binary i/o; so newline translation should ideally be able to be turned off with a switch.)
  • Instead of having the user hit the "Enter" key, expect the user to do something else to give a 10 to the interpreter; e.g., the user can feed the input from a file which uses 10s to end the lines, rather than from the keyboard. Send the output to a file too. (Possible but clunky.)

A few implementations allow the input to be "raw" and sometimes non-blocking. If the input is in "raw" mode it is not line buffered and key presses are passed to the program immediately. Non-blocking means that if there isn't a character available either immediately or after a short delay (for example 1/10 of a second) the input command will return an EOF indication.

EOF

EOF is a controversial issue. Many implementations return 0, some return -1, and several notable brainfuck programmers suggest that on EOF the memory cell should be left as-is, without modification. In the original distribution the compiler left the cell unchanged, while the interpreter used the EOF from C which, strictly speaking, could be any negative integer, but which usually is -1 (which, in the case of byte-sized cells, ends up as 255).

Conventions

The following summarizes the common conventions for making a brainfuck interpreter or compiler. It can be seen as a general specification for brainfuck, commonly accepted amongst the brainfuck community as a minimal base. It attempts to solve implementation issues by standardizing them.

Memory

  • Memory should normally consist of 8 bit cells, a very fast compiler may use 32bit or larger cells. Floating point cells are strongly discouraged as are cells that are not a power of two in size. "Bignum" cells are allowed but should be an option.
  • Memory should wrap on overflow and underflow. (This also includes the [-] function with "bignum" cells).
  • Negative memory addresses should NOT be assumed to exist, however, an interpreter may provide some. (An optimising interpreter may be forced to)
  • Memory should consist of at least 30000 cells, some existing brainfuck programs do need more so this should be configurable or unbounded.

Newlines

The input should be "line buffered" until the user enters a newline at which point the program receives the edited line.

  • OS newlines should be converted to 10 for input.
  • 10s should be converted to OS newlines for output.

Note that most programming platforms and programming languages already do this for you, which might make converting 10s to OS newlines redundant.

Character set

The original brainfuck interpreter used the native character set of the host, ISO8859-1. Most modern brainfuck interpreters do the same, so this means that many current implementations will used UTF-8 as the character set and have access to ANSI control sequences. The majority of brainfuck programs only use ASCII with newlines, but the few that use extended sets follow the UTF-8+Ansi pattern.

EOF

An interpreter should normally either return Zero or leave the cell unchanged on EOF.

The Zero option matches the brainfuck language in that the only conditional in brainfuck is a comparison with zero. Using this form, in theory, allows slightly shorter code. For eight bit cells the "leave the cell untouched" matches the C/Unix read(2) system call in that the character memory will be left unchanged on EOF. For Unix the EOF (or error) condition is signalled by the return value, which is lost with BF. If the interpreter's cells are more than eight bits the "unchanged cell" can safely handle binary data. If the cells are eight bit or the interpreter sets the cells to zero on EOF binary data cannot be handled.

For a brainfuck program this means that ASCII data+EOF should be read using a [-], construct (or similar). Binary input should, probably, be read using a construct of the form [-]-,. This requires that input bytes are in the range 0..255 when the cell size exceeds eight bits.

Note: It is strongly recommended that an interpreter be configurable to all three normal form of EOF (Zero, minus one and unchanged).

Extensions

Some implementations also recognize the following symbols as meaningful:

# Start debugger (e.g. Print contents of first few memory cells)
! Separate code from input

The debug command # comes from brainfuck's original interpreter, written by Urban Müller. Because brainfuck programs have only one input source, brainfuck interpreters written in brainfuck (or other languages without file I/O) require ! to be able to distinguish a program's code from the input it is intended to process.

As all characters other than ><+-.,[] should be considered comments and ignored, it is normal for an interpreter to have a method of disabling these extensions if required. This disabling may be automatic for '!' based on such things as if there is currently an open loop and/or if the program is being read from the 'standard input'.

As these commands are non-standard some interpreters use different codes for these functions.

Probably the next most frequently implemented extension is a command to comment out the rest of the line, however, experienced brainfuck programmers generally consider this useless mostly due to the existence of the header comments technique.

Related languages

In publishing the formal programming language P'' in 1964, Corrado Böhm used six symbols precisely equivalent to the brainfuck commands +, -, <, >, [, and ], and provided an explicit program for each of the basic functions that together serve to compute any partial recursive function. (So in a very real sense, the first "brainfuck" programs appear in Bohm's 1964 paper.)

Many people at various times have tried to extend brainfuck to make it easier to program in, but such efforts have been compared to trying to make a luxury car by gluing parts onto a skateboard. Other people have been interested in variations of the language for theoretical purposes, pedagogical applications, etc. The sheer proliferation of languages equivalent to and derived from brainfuck led Chris Pressey to dub it "the twelve-bar blues of esolang". Some of the more interesting variants:

  • pbrain is a brainfuck extension that supports procedures.
  • cbrain is a derivative of pbrain as implemented in pbrain.c, adding integers and operators.
  • RUM stands for "bRainfUck iMproved." and adds procedures, strings and repetition.
  • Toadskin is a brainfuck variant that supports procedures, but uses a stack instead of an array.
  • Brainfork adds a Y command to fork the current thread.
  • Fm edits a string on alphabet {0,1,...,m-1} (m >= 2).
  • FRAK assembles instructions to brainfuck code.
  • FukYorBrane and BF Joust pit two Brainfuck-like programs against each other, as in Core War (see Redcode).
  • Smallfuck operates only on bits and has no input- or output-commands.
  • Bitter one-bit memory cells, four commands, equivalent to Smallfuck under certain circumstances
  • Spoon uses a Huffman coded set of instructions corresponding to Brainfuck's commands.
  • BrainDuino BF port on Arduino HW platform (based on Atmel's ATMega). Extended by two special I/O operations and special overflow protection.
  • Puzzlang turns every program into an exercise in patience and logic puzzle skills. The lone X operator becomes any of brainfuck's instructions, depending on the surrounding characters.
  • Alarm Clock Radio throws away the instructions to decrement the memory pointer or memory value.
  • Portal and Portal 2 allows code-level pointer manipulation and theoretically implements the Wang-B Machine.
  • tbf is a language that can be compiled to Brainfuck. It includes variables, strings, macros and improved loops.
  • Grin adds more efficient arithmetic functions to Brainfuck.
  • tinyBF and its variant RISBF are brainfuck equivalents with only 4 opcodes.
  • Grawlix adds stack operations, decimal I/O, another loop structure, functions and multiply/divide by two.
  • brainfuckconsole74 extends brainfuck to a fantasy console like pico8. it renders first 256 cells as 16x16 pixels, reads keyboard&mouse-input and plays sound.
  • Motherf adds a variety of useful commands and principles like macros, stack, functions, convenient I/O, booleans and simulation of other types.
  • BFFuck and Headache are high-level languages that compile to brainfuck.
  • brainbits is a brainfuck derivative that uses bit cells.

Some other funny variants:

  • Ook! works exactly like brainfuck, except the syntax is in Orangutan.
  • Blub is the same for fish.
  • Brainloller has the same commands as brainfuck, except they're read from a png image.
  • COW is the bovine version of "Ook!", except cows are slow to react so the loops are different.
  • Pi obfuscates Brainfuck instructions in random errors in pi digits.

Some languages inspired by brainfuck, but with more major differences:

  • Aura requires data to be stored in the code space.
  • PATH and SNUSP attempt to combine brainfuck with Befunge.
  • Wierd arose out of an earlier attempt to combine brainfuck with Befunge.
