REPL Usage

The Read-Eval-Print Loop (REPL) allows interactive execution of Kexra code, perfect for experimentation and testing snippets.

Why this exists​

REPL provides immediate feedback without creating files, enabling quick testing of ideas and learning through trial and error.

How it works​

Start REPL with kex repl, then enter statements or expressions. Each line is evaluated immediately, with results displayed.

Examples​

$ kex repl
> say "Hello"
Hello
> set x = 42
> say x
42
> x + 8
50

Common mistakes​

  • Expecting multi-line statements (REPL evaluates line by line)
  • Forgetting semicolons aren't needed (Kexra uses newlines)
  • Using file-specific features like imports
