Sembly

Sembly is a cell-based esolang similar to brainfuck except the cells are binary - meaning they can only hold a single bit: 0 or 1, and only uses 7 parameter-less functions. It is equivalent to Boolfuck with an inverted loop condition.

Functions

• inp - inputs a single 1 or 0 bit to the cell at the pointer
• out - outputs the cell at the pointer
• left - shifts pointer left
• right - shifts pointer right
• flip - logical NOT on the cell at the pointer (0 becomes 1, or 1 becomes 0)
• loop - enters loop if cell at the pointer is 0, and continues looping until the cell at the pointer equals 1
• end - ends loop

Note: the loop function is used for both loops and conditionals/if-statements.

Interpreter

Interpreter made in Python (not strictly tested)

Note: Requires making a file in the same directory by default called 'program.txt'

import os

def skip(i, program):
  depth=0
  for x in range(i+1, len(program)):
    if 'end' in program[x]:
      if depth==0:
        return x+1
      else:
        depth -= 1
    if 'loop' in program[x]:
      depth += 1
  
def cont(i, program):
  depth=0
  for x in range(i-1, -1, -1):
    if 'loop' in program[x]:
      if depth==0:
        return x
      else:
        depth-=1
    if 'end' in program[x]:
      depth += 1

array = [0, 0, 0]
clipboard = 0
pos = 0

program = open(f'program.txt', 'r').readlines() 

i = 0
while True:
  
  try:
    line = program[i]
  except:
    break
  
  if 'inp' in line:
    array[pos] = int(input('> '))
  
  elif 'out' in line:
    print(array[pos])
  
  elif 'left' in line:
    pos -= 1
  
  elif 'right' in line:
    array.append(0)
    pos += 1
    
  elif 'loop' in line:
    if array[pos] != 0:
      i = skip(i, program)
      continue
    
  elif 'flip' in line:
    array[pos] = 1-array[pos] 

  elif 'end' in line:
    i = cont(i, program)
    continue

  i += 1
