Vladimir Kotikov updated CB-10052:
----------------------------------
Description:
Sometimes it is useful to process spawned process stdout and stderr in some way
before out this to console. The current implementation of superspawn doesn't
give a way to do this. One of the cases when this could be helpful - CB-9971
(see https://github.com/apache/cordova-android/pull/240 for some discussion).
The proposed approach is:
1. Add ability to accept any valid stdio configuration, just like the original
child_process.spawn does
(https://nodejs.org/api/child_process.html#child_process_options_stdio)
2. Give a way to caller to listen to stdout and stderr events. This might be
implemented as resultant promise progress notification:
{code:JavaScript}
spawn('mycommand', [], {stdio: 'pipe'})
.progress(function (stdio){
if (stdio.stderr) {
console.error(stdio.stderr);
}
})
.then(function(result){
// do other stuff
})
{code}
