Support all node CLI flags

[blakeembrey]

Should be able to enable things like --harmony from ts-node --harmony script.ts. Good place to start: https://github.com/babel/babel/blob/master/packages/babel-cli/src/babel-node.js

May be tsc flags such as --experimentalDecorators as well?

[blakeembrey]

That's probably doable, but it is already possible using tsconfig.json.

I'm personally interested in passing the --debug flag to node. Would you accept a PR for that or are you more interested in a general solution?

On the general side, rather than fancy auto-detect that Babel did there, how about something blindly forwards user specified options on the generated node command, e.g. --forwardOption --debug.

[blakeembrey]

@neomantra yes, I'm perfectly happy with that - that would be my preferred solution.

@blakeembrey Thanks, I was just looking for this feature today, and see it was just pushed yesterday with 0.9.2. But it's not clear to us it - is it documented somewhere?

[blakeembrey]

@danielnaab ts-node --debug script.ts

[danielnaab]

@blakeembrey Hmm, I had tried ts-node --harmony_default_parameters script.ts. Should that work? With that form I get the REPL instead of the script executed.

[blakeembrey]

You're right, sorry. Looks like the functionality is a little broken because of https://github.com/TypeStrong/ts-node/blob/master/src/_bin.ts#L72. We might need to invert that check and consider every argument that's a string as a string and treat the rest as boolean.

[blakeembrey]

Either that, or have the first bin script (https://github.com/TypeStrong/ts-node/blob/master/src/bin.ts) strip out the node arguments it finds first before passing them along.

@danielnaab Fixed it with e9c7012. Update to 0.9.3 and try again.
