Also known as Brainfuck. Created by Urban Müller in 1993 in an attempt to create the world's smallest Turing-complete compiler. It is noted as an [[esoteric programming language]], as it is not ordinarily used for applications development, but it also noted as being a minimalist language.
The complete specification for the language can be summed up with the following eight symbols:
{| class="wikitable"
!align="center"|Character
!align="left" |Meaning
|-
|style="text-align:center"|<code>></code>
||increment the pointer (to point to the next cell to the right).
|-
|style="text-align:center"|<code><</code>
||decrement the pointer (to point to the next cell to the left).
|-
|style="text-align:center"|<code>+</code>
||increment (increase by one) the byte at the pointer.
|-
|style="text-align:center"|<code>-</code>
||decrement (decrease by one) the byte at the pointer.
|-
|style="text-align:center"|<code>.</code>
||output the value of the byte at the pointer.
|-
|style="text-align:center"|<code>,</code>
||accept one byte of input, storing its value in the byte at the pointer.
|-
|style="text-align:center"|<code>[</code>
||jump forward to the command after the corresponding <code>]</code> if the byte at the pointer is zero.
|-
|style="text-align:center"|<code>]</code>
||jump back to the command after the corresponding <code>[</code> if the byte at the pointer is nonzero.
|}
Alternatively, the <code>]</code> command may instead be translated as an unconditional jump '''to''' the corresponding <code>[</code> command, or vice versa; programs will behave the same but will run more slowly.
All other symbols, including traditional whitespace characters, are interpreted as comments.
Due to this minimal instruction set, Brainf*** is used as an introduction to compilers and has even been successfully implemented as a microprocessor core and the foundation to an operating system using a slightly extended syntax for output.
