Easy!
var ez = require('ez-streams');
var reader = ez.devices.file.text.reader('mystuff.txt')
.transform(ez.transforms.lines.parser());
// now you can use reader.read(cb) to read one line at a time.
You can also apply further transforms, filter, map, etc. For example:
reader = reader.filter(function(cb, line) {
cb(null, /^[^#]/.test(line))
}).map(function(cb, line) {
cb(null, line.toUpperCase();
});
// reader is now a reader which skips comment lines (starting with #) and
that turns the lines to uppercase..
