node repl tricks

repl.js

// add ;0 to suppress long results, like a process or a mongoose connection
process;0

// capture information from async calls. doesn't work on calls that use the arity. make a custom call for those.
var results = [], capture = function() { results.unshift([].slice.call(arguments)) }

// handle uncaught exceptions so a mistake in the console doesn't bounce you out of your session
process.on('uncaughtException', function(err) { console.log('***uncaught***', err); });0
