XBrain is an experimental programming language inspired by Brainfuck, derived from skeeto/bf-x86.

Language overview

Brainfuck consists of 8 commands as following,

  • +: Increment the data pointer, equal to (*ptr)++ in C.
  • -: Decrement the data pointer, equal to (*ptr)-- in C.
  • > :Increment the byte at the data pointer, equal to ptr++ in C.
  • < :Decrement the byte at the data pointer, equal to ptr-- in C.
  • . :Output the byte at the data pointer as ascii character, equal to putchar(*ptr) in C.
  • , :Accept one byte of input, storing its value in the byte at the data pointer, equal to getchar() in C.
  • [ : Equal to while(*ptr) in C.
  • ] : Equal to } in C.

XBrain consists of additional 4 commands as following,

  • / : Comment
/this is comment
++++++++++++++++++++++++++++++++++++++++++++++++.

-> 0
  • $ : Print the byte at the data pointer as a hex number.
+$

-> 0x1
  • &: Do Logical conjunction between the byte at the data pointer and the byte at left (=previous ) cell.
/0x22

/0x35

-> 0x20
  • |:Do Logical disjunction between the byte at the data pointer and the byte at left (=previous ) cell.
/0x22

+++++++++++++++++++++++++++++++++++++++++++++++++++++|$

-> 0x37

get started

Binary

Binary distributions are available with following command:

$ curl https://static.psaux.jp -o xbc

From Source

You can also get XBrain compiler from source with following command:

$ git clone https://github.com/wf001/xbrain
$ cd xbrain
$ make

Make sure you have installed the dependencies:

  • gcc
  • make

And you can make ELF-formatted Executable file with following command:

$ ./xbc [your_file].xb // generate ELF-formatted file
$ ./[your_file] //run
