.from( '"1","2","3","4"\n"a","b","c","d"' )
.to( console.log )
// Output:
// 1,2,3,4
// a,b,c,d

Advanced example

// node samples/sample.js
var csv = require('csv');
csv()
.from.stream(fs.createReadStream(__dirname+'/sample.in'))
.to.path(__dirname+'/sample.out')
.transform( function(data){
  data.unshift(data.pop());
  return data;
})
.on('record', function(data,index){
  console.log('#'+index+' '+JSON.stringify(data));
})
.on('end', function(count){
  console.log('Number of lines: '+count);
})
.on('error', function(error){
  console.log(error.message);
});
// Output:
// #0 ["2000-01-01","20322051544","1979.0","8.8017226E7","ABC","45"]
// #1 ["2050-11-27","28392898392","1974.0","8.8392926E7","DEF","23"]
// Number of lines: 2

Migration

The functions 'from*' and 'to*' are now rewritten as 'from.' and 'to.'. The 'data' event is now the 'record' event. The 'data' now recieved a stringified version of the 'record' event.

Development

Tests are executed with mocha. To install it, simple run npm install, it will install mocha and its dependencies in your project "node_modules" directory.

To run the tests:

npm test

The tests run against the CoffeeScript source files.

To generate the JavaScript files:

make build

The test suite is run online with Travis against Node.js version 0.6, 0.7, 0.8 and 0.9.
