How To Install:

Interpreter:

• Download BFITPT.8xp to your GC (Ti-84 Plus C SE / Ti-84 Plus CE / ...).
• Edit brainfck source code(Str0)
• Run it.

Editor:

• Download EDITOR.8xp to your GC (Ti-84 Plus C SE / Ti-84 Plus CE / ...).
• Run it.

Features:

• Automatically add new line when reaching the end of a line.
• ClrHome when newline is needed at the last line of the screen.
• Memory currently contains 900 cells and the maximum depth of loop allowed is 400, due to constraints of the GC.
• Memory is wrapped on overflow and underflow (Cell(-1)=Cell(900), Cell(901)=Cell(1)).
• Only the 8 command chars are allowed to be in the source.
• Cells are emulated as to be 8-bit (0-255).
• Use ASCII printable characters as input/output.
• Currently only allows numbers and ALPHA characters(excluding theta and SOlVE) as input.
• Type capital letters by pressing 'ALPHA' key followed by the letter keys.
• Type numbers by directly pressing the number keys.
• " sign is always automatically replaced by ' sign because GC does not allow the use of " in string variables.
  • Both "(ASCII:34) and '(ASCII:39) are shown as ' in output.
  • " ("ALPHA" + "+") is converted to 34 in input.
• \ sign is always automatically replaced by / sign due to constraints of the GC.

Todos:

• Add line buffer so as to move all lines up instead of clrhome when reaching the last line.
• When editting source code:
  • Allow non-command chars as comment (which are ignored by the interpreter) (is it necessary?)
• Translate newline to 10 on input, and 10 to newline on output
• Display instructions at the start (to be added when all functions are complete)
• Show cursor when waiting for input
