Brainf**k Tutorial

                    
Brainf**k is a programming language with only 8 commands:

                    
    
                        
  • > Move pointer right
    • 
                        
  • < Move pointer left
    • 
                        
  • + Increment memory at pointer
    • 
                        
  • - Decrement memory at pointer
    • 
                        
  • . Output character at pointer
    • 
                        
  • , Input character to pointer (from Input)
    • 
                        
  • [ Jump forward past matching ] if memory at pointer is 0
    • 
                        
  • ] Jump back to matching [ if memory at pointer is not 0
    • 
                    

                    
How to Use This UI

                    
    
                        
  • Write Brainf**k code in the Code tab.
    • 
                        
  • Click Run to execute, Stop to halt, Reset to clear memory/output/screen.
    • 
                        
  • Use the Input field for , commands
    • 
                        
  • View memory in the Memory tab.
    • 
                        
  • Game Mode: When enabled, the first 256 memory cells are visualized as a 16x16 pixel screen (see below). The . command updates the screen, instead of printing a character to the output.
    • 
                        
  • When Game Mode is off, . prints to the output.
    • 
                        
  • When Color Screen is enabled, the screen is colored (see below), else the screen is grayscale (0 - 255).
    • 
                    

                    
Colors Legend

                    

                        
Each value (0-255) is mapped to a unique color: 16 hues × 16 brightnesses.
Hue = value % 16, Brightness = value / 16. Used for Color Screen mode.
