spawn-to-readstream

$3

Make child process spawn behave like a read stream (buffer the error, don't emit end if error emitted).

$3

``bash
npm install spawn-to-readstream
`

$3

`js
var toReadStream = require('spawn-to-readstream'),
spawn = require('child_process').spawn;

toReadStream(spawn('ls', ['-lah'])).on('error', function(err) {
throw err;
}).on('end', function() {
console.log('~~~ DONE ~~~');
}).on('data', function(data) {
console.log('ls data :::', data.toString());
});
`

Limiting the output of the steam

`js
var toReadStream = require('../index'),
spawn = require('child_process').spawn,
limit, buf;

buf = 0;
limit = 100 * 1024; // 100 Kb

// Note that it's a 'soft' limit, meaning the data you
// receive might be > 100 Kb, because the child process
// was stopped after receiving more than bytes
toReadStream(spawn('cat', ['/dev/urandom']), limit)
.on('error', function(err) {
throw err;
}).on('end', function(isLimited) {
console.log('done, ' + buf + ' bytes received');
if (isLimited) {
console.log('child process was cut');
}
}).on('data', function(data) {
buf += data.length;
});
`

`bash
npm test
