Does anybody know how to open 2 console/terminal windows to stream logs into them?

[Sergey Lapin]

Preferably on windows.

I have several duplex streams which I want log in different places. I would very convinient  to stream them to separate console windows, because I use tdd with live coding. Files are not suitable here.

You basically only get one console window per console process on Windows.  In theory you could do this with native code, but I doubt anyone has and exposed it in a node module.  So, the simplest solution is to have multiple processes.  The easiest way to do this would be to effectively pipe your logs through a file, assuming you have "tail" installed, or something like it (there's probably one written in node in npm), you can do something like this:

var logger1 = fs.createWriteStream('log1.txt');
var logger2 = fs.createWriteStream('log2.txt');

child_process.exec('start "Log 1" tail -f log1.txt');
child_process.exec('start "Log 2" tail -f log2.txt');
logger1.write('To the first!');
logger2.write('To the second!');

You can probably do something more complicated with actual pipes instead of files, and have the sub-processes be something like "type" or "cat" which exit automatically upon a broken pipe.
