brainkFuck-PHP-methodChain

Implementation of BrainFUck using a PHP method chain For some reason I felt like implementing the brainFUck language using a method chain instead of using some lexer and parser. At least this gives it the speed of executing a normal PHP file plus this is way easy to do compared to dealing with lexers and parsers.

Want to run this ?

• First make sure you have good old PHP installed.
• Next cd into the brainFuck-PHP-methodChain dir and start the inbuilt PHP server php -S localhost:5050.
• Feel free to edit the Hello World! example or just write your own.

BrainFUck Syntax

• ->shiftFwd() or ->shiftFwd(n) decreament the data pointer (by one or n respectively) to point to the next cell to the right.

• ->shiftBck() or ->shiftBck(n) decrement the data pointer (by one or n respectively) to point to the next cell to the left.

• ->inc() or - ->inc(n) increment (increase by one or n respectively) the byte at the data pointer.

• ->dec() or - ->dec(n) (decrease by one or n respectively) the byte at the data pointer.

• ->output() output the byte at the data pointer. Also pass in false to mute output.

• ->input() accept one byte of input, storing its value in the byte at the data pointer.

• ->label('sample_label') if the byte at the data pointer is zero, then instead of moving the instruction pointer forward to the next command, jump it forward to the command after the matching ->jmp('sample_label') command.

• ->jmp('sample_label') if the byte at the data pointer is nonzero, then instead of moving the instruction pointer forward to the next command, jump it back to the command after the matching ->label() command.
