Simplistic REPL for CasperJS

repl.js

// Usage: require('repl').start.call(this);
// Press Ctrl+D to continue script
// Press Ctrl+C to exit.

require = patchRequire(require);

var system = require('system');
var utils = require('utils');

exports.start = function(prompt) {
  prompt = prompt || '> ';

  var line, _;

  do {
    system.stdout.write(prompt);
    line = system.stdin.readLine();

    if (system.stdin.atEnd()) {
      break;
    }

    try {
      _ = eval(line);
      console.log(_);
    } catch (e) {
      console.log(e);
    }
  } while (true);
}

Hi, I had the same problem. Did you solve it?

This gist is written as a CasperJS module (see http://docs.casperjs.org/en/latest/writing_modules.html). It should be used from within the context of a normal CasperJS script. eg. in your script, add this line somewhere near the top:

var repl = require('./repl');

and at the point in your script that you want to drop into the REPL, add this line:

repl.start();
