Brainfuck, programazio lengoaia esoterikoa da, Urban Müller-ek diseinatuta 1993. urtean. Helburutzat lengoaia sinplea eraikitzea zen, Turing osoa eta konpiladore txiki behar zuena. Brainfuck Turingen makinan oinarritu zen, eta 1024 byteko konpiladoreari inspirazio gisa erabili zen, FALSE lengoaian erabiliko zena.

Lengoaiaren diseinua |
Lengoaia exekuzio modelo sinple batean oinarritzen da, programaz aparte, bektore bat 30000 bytekoa (0ra hasieratutakoak), erakusle bat bektore horretara erakusten duena (hasieran bektorearen lehengo elementura erakusten du) eta bi byte “korronte” sarrera eta irteera burutzeko.
Aginduak |
8 agindu ditu soilik, guztiak karaktere bakarrekoak.
| Karakterea | Esanahia |
|---|---|
> | Erakuslea gehitzen du. |
< | Erakuslea kentzen du. |
+ | Erakutsitako bytea gehitzen du. |
- | Erakutsitako bytea kentzen du. |
. | Erakutsitako bytearen irteeran idatzi. |
, | Byte bat irakurri sarreratik eta erakutsitako bytean gorde. |
[ | Aurreratu ] ren ondorengo agindura baldin eta erakutsitutako bytea nulua bada (0 bada). |
] | Itzuli [ ren ondorengo agindura baldin eta erakutsitutako bytea nulua ez bada (0 ez bada). |
Beste lengoaietara itzuli |
Brainfuck programak C eta Perl lengoaietara itzuli daitezke honako aldaketag eginez. Suposatuz ptr aldagaia unsigned char* motakoa dela.
| brainfuck | C | Perl |
|---|---|---|
> | ++ptr; | $pointer++; |
< | --ptr; | $pointer--; |
+ | ++*ptr; | $tape[$pointer]++; |
- | --*ptr; | $tape[$pointer]--; |
. | putchar(*ptr); | print chr$tape[$pointer]; |
, | *ptr=getchar(); | $tape[$pointer]=ord(<>); |
[ | while (*ptr) | while($tape[$pointer]) |
] | | |
