What is Eta REPL?


The principles we strive to follow in the Eta REPL are:

  • Aesthetic
  • Intuitive
  • Scalable


The REPL should look pleasant to the eyes and make you want to use it as much as possible.


The REPL should commands should have memorable names for the function they perform and there should be little friction for day-to-day use. In other words, it shouldn't get in your way!


The REPL should be fast whether you are working on a one module project or a 1,000 module project.
