_Video depicting a Bf3d program running as it fills in a diamond shaped 3d shape on the screen_

Bf3d is a simple esoteric programming language inspired by BrainFuck and like languages. Bf3d uses the same basic syntax as BrainFuck, but replaces + and - with R G and B which increment colors and r g b to decrement a color. Also, because the program works in 3 dimensions, the program can move the cursor left and right with > and < like usual, but the cursor can also move up and down with ^ and v. Each cell is represented as an 8-bit number. An additional keyword l followed by a number specifying the layer that the program operates over.

8-bit color format

Technical details

This compiler uses flex and lemon to lex and parse the program. The program is then stored in a bytecode format in memory that is then run following the rules of the program until it completes. The graphics are done using raylib.

Example Program

To draw the diamond in the example above, one would write the program:

l0:>>>>^^^^+.
l1:+[>>>>^^^^[
      >BB
      <^BB
      <VBB
      V>BB
    ^.-<<<<VVVV-]<<<<VVVV]

l2:+[>>>>^^^^[
      >>BBB
      <^BBB<^BBB
      <VBBB<VBBB
      V>BBBV>BBB
      >^BBB
    ^<.-<<<<VVVV-]<<<<VVVV]

l3:+[>>>>^^^^[>>>GGG
      ^<GGG^<GGG^<GGG
      V<GGGV<GGGV<GGG
      V>GGGV>GGGV>GGG
      ^>GGG^>GGG
     <<^.-<<<<VVVV-]<<<<VVVV]

l4:+[>>>>^^^^[>>>GG
      ^<GG^<GG^<GG
      V<GGV<GGV<GG
      V>GGV>GGV>GG
      ^>GG^>GG
     <<^.-<<<<VVVV-]<<<<VVVV]

l5:+[>>>>^^^^[
      >>RR
      <^RR<^RR
      <VRR<VRR
      V>RRV>RR
      >^RR
    ^<.-<<<<VVVV-]<<<<VVVV]

l6:+[>>>>^^^^[
      >RRR
      <^RRR
      <VRRR
      V>RRR
    ^.-<<<<VVVV-]<<<<VVVV]
l7:+[>>>>^^^^[-RRRR <<<<VVVV-]<<<<VVVV]
