🐝 bee

Bee is a simple programming language I created as a personal learning project. It was born out of my desire to delve deeper into the world of compilers and interpreters. I wanted to understand how code transforms from human-readable instructions into something a computer can understand.

  • <= Less than or equal to
  • != Not equal to
  • == Equal to
  • = Assignment
  • ! Logical negation
• Identifiers:
  • A sequence of letters, digits, and underscores, starting with a letter or underscore.
• Keywords:
  • mut Declares a mutable variable.
  • echo Outputs a value to the console.
  • nil Nill value.
  • true | false Booleans.
• Comments:
  • Single-line comments start with //.

Statements:

• Echo Statement: Outputs a value to the console.

  echo "Hello, World";
  echo 10 * 5;

• Expression Statement: Evaluates an expression.

  10 * 5 --5;
  variable = 10;
  !true == false;

• Variable Declaration: Declares a variable.

  mut? name = "drezzy"; // constant
  mut age = 18;

Interpreter

Bee comes with a simple interpreter called cbee. You can install it using npm:

npm i cbee --g

Running Bee Code:

• REPL: Start the interactive REPL:

  cbee

• Running a file: Run a Bee file:

  cbee [filename]

• Help: Display help information:

  cbee --help

Example Program

// This is a comment
mut name = "Bee";
mut age = 1;

echo "Hello, " + name + "!";
echo "You are " + age + " year(s) old.";
