[nodejs] redirect/intercept stdout within node

[Dominic Tarr]

hi,

I'm trying to figure out how to capture the stdout produced within a block of code, say, to test that the stdout is correct.

although this seems fairly straightforward to do is the likes of ruby, I can't figure out how to do it in nodejs

can anyone give me any clues?

process.stdout.write = (function(write) {
    return function(string, encoding, fd) {
        write.apply(process.stdout, arguments)
    }
})(process.stdout.write)

It's a global hook, so if you only want to apply it to a certain block it would be on you to remove it after the block finishes.  Also note that technically it could accept either a string or a buffer.

Fleshed it out a bit.
