stdin + arguments composite stream

install

npm install diamond

example

pipe stdin and content of files from command line to stdout:

var diamond = require('diamond');
 
diamond().pipe(process.stdout);

listen for 'next' event:

var diamond = require('diamond');
 
var stream = diamond();
 
stream.on('data', function(d) {
     console.log('data:', d);
});
stream.on('end', function() {
     console.log('end');
});
stream.on('next', function() {
    console.log('next stream!', stream.name);
});
 

by default, process.argv.slice(2) is used as list of files. You can pass your own list:

var program = require('commander');
var diamond = require('diamond');
 
program
  .version('0.0.1')
  .option('-c', 'Count chars')
  .option('-l,', 'Count lines')
  .parse(process.argv);
 
var stream = diamond(program.args);
