write to stdout

[bryanlarsen]

Is there any way to write to stdout rather than to files? Since jk is hermetic there's no reason to save the input, I can just stream it to kubectl apply -f -.

#93 is pretty much required for this to be useful, but works great.
#125 is related but a much bigger ask.

Yes!

$ cat stdout.js 
import std from '@jkcfg/std';


const o = {
  foo: 2,
  bar: [1, 2, 3],
};

std.write(o, '', { format: std.Format.YAML });

$ jk run stdout.js
bar:
- 1
- 2
- 3
foo: 2

And with YAMLStream for multiple documents:

$ cat stdout.js 
import std from '@jkcfg/std';


const o = {
  foo: 2,
  bar: [1, 2, 3],
};

std.write([o, o], '', { format: std.Format.YAMLStream });

$ jk run stdout.js
bar:
- 1
- 2
- 3
foo: 2
---
bar:
- 1
- 2
- 3
foo: 2

Thanks! I tried '-', but didn't think to try ''.

Any chance of a release soon? I ended up using YAMLStream and #135 and having co-workers download an unreleased version is a little bit icky. :)

Yes, can do, probably tomorrow though if that's ok.
