Consider shx REPL

[levithomason]

Was toying with a thin streaming wrapper around the shx function. Would be cool to give this some thought. There is good potential to create a cross platform shell repl:

This also raised some issues with how we are accepting argv in shx and parsing them in parseArgs. I'll wait until we get some of the other more fundamental issues/PRs cleared before digging in more.

Leaving this issue here as food for thought, for now.

Would this have any benefit over dthree/cash?

Not sure, i'm not completely familiar with their work. This was just so easy to do it seemed like it was worth considering:

#!/usr/bin/env node
const shx = require('./lib/shx');

const PROMPT = 'shx› ';

process.stdout.write(PROMPT);

process.stdin.on('data', data => {
  // arg parsing in shx is awkward,
  const argv = ['', ''].concat(data.toString().replace(/\n$/g, '').split(' '));
  shx(argv);
  process.stdout.write(`\n${PROMPT}`)
});

I'll take a closer look at cash later and see what the extra benefits would be, if any.

If this is simple enough to get right, I'm fine with this. It seems like an awesome feature!

It seems similar to a project we were thinking of starting, which would be a node REPL that includes the latest version of ShellJS already required (globally), so commands like cp() are immediately available (if there's any interest in helping with that as well). It might be nice to have a coffee script REPL too, since it's a bit easier to type that stuff out (it'd be more shell-like).

I think that we should just defer this to cash, which is more complete.

Agreed for now, given bandwidth constraints and the scope of this add.
