works and doesnt

var fs = require('fs') // WORKS! Outputs file line by line.
var liner = require('./liner')
var source = fs.createReadStream('./hhh.in')
source.pipe(liner)

// var testcases, matrix_size
liner.on('readable', function () { 
     var line;
     // var testcases = liner.read();
     console.log(liner.read());
     while (line = liner.read()) {
          console.log(line);
     }
})



var fs = require('fs') // Doesn't work. The act of storing in var destroys everything?
var liner = require('./liner')
var source = fs.createReadStream('./hhh.in')
source.pipe(liner)

// var testcases, matrix_size
liner.on('readable', function () { 
     var line;
     var testcases = liner.read();
     // console.log(liner.read());
     while (line = liner.read()) {
          console.log(line);
     }
})
