Captl

A fun interpreter inspired by Brainfuck made in java

Function

Captl works by using letters and symbols as tokens. It also uses Capitalisation for more tokens. It uses a simple byte memory system for operations like Brainfuck.

Tokens

The token syntax is as Simple as in Brainfuck, but some tokens have arguments

• H - Highers the current byte by 1
• h - Lowers the current byte by 1
• p - Prints the current byte as ascii character
• P - Prints all bytes in memory as ascii character
• N - Switches to the next memory cell
• n - Switches to the previous memory cell
• i - Takes the next char from input and puts into the current cell
• I - Takes the next line from input and puts into the memory
• e - Empties the byte buffer
• E - Empties the current memory cell
• V[variable identifier] - V saves the current memory cell into the given variable
• ; - Starts or ends a comment
• A<number/variable> - Adds the following number to the current cell
• D<number/variable> - Subtracts the following number from the cell
• d"<string>" - Decodes a String into memory
• r<number/variable><token> - Repeats the token times the given number
• R<number/variable> - Sets the recursion_number pointer to the given number
• [ - Enters the while(block != recursion number) loop
• ] - jumps back to [ if block != recursion_number

Variables

Variables are identified by special characters such as !"§$%&/)=?*+~'#-_.:,;<>|^° which can only consist of only 1 of predefined characters

Usage

Captl can be accessed via the command line like this.

• java -jar Captl.jar -f file.captl - Executes from the given file
• java -jar Captl.jar -i - Opens the live interpreting console
• java -jar Captl.jar <Captl Code> Directly executes the given code from command line
