[Feature request] Add REPL

[MaxGraey]

It will be nice to have REPL with history and minimal environment. I guess we could reuse some urils from node.js like "repl" module:

const Repl  = require('repl');

const repl = Repl.start({
  prompt: 'assemblyscript> ',
  useColors: true,
  ignoreUndefined: true
});

repl.on('line', line => {
   line = line.trim();
   // try compile assemblyscript for this line here
});

Since we are talking about a static compiler here that cannot evaluate an additional line ad-hoc, it looks like the only way this can be done is to keep a complete history of the input (discarding invalid input) and recompile everything with a new line added, including any variable assignments, function calls etc. This might work somehow, but I wonder if it's a good match due to compile time delay.

I guess it possible. For example Rust has some unofficial crates for this. Like evcxr_repl and runner. Also see RFC proposal.
