standard input and output

[Teemu Ikonen]

Hi,

We needed way to control phantomjs binary by stdin and stdout for using it as queued rendering engine and noticed that reading from /dev/stdin and /dev/stdout with require('fs').open('/dev/stdin').readLine() didn't work as expected and blocked until end of file mark. Also those device files are not available in all platforms. I added stdin, stdout and stderr file objects as standard members to filesystem object, so its possible to do this:

var stdin = require('fs').stdin();

var line;

while( line = stdin.readLine() ) {

   console.log( line );

}

I would like to get this or something similar on the main release, any comments if it's right approach for stdout/stdin or how to improve this?

Thanks, Teemu I.

If I understand this correctly: http://wiki.commonjs.org/wiki/System/1.0

Then these methods should be in the system module.

cheers

Good point, I'll move the stdin/err/out as objects in system module

var stdin = require('system').stdin;

var line;

while( line = stdin.readLine() ) {

   console.log( line );

}

See also http://code.google.com/p/phantomjs/issues/detail?id=333 (and
the linked pull request). It's already almost fully implemented, just
needs some clean-up.
