Nostalgic command-line invoicing application producing plain text invoices and JSON data structures. Uses the file system as a database

    out = require('./out'),
    paths = state.get('paths'),
    Api = require('invoice-api'),
    fs = require('fs'),
    writeDataSync = require('./writeDataSync');

function Customer(code) {
    this.type = 'customer';
    this.open(code);
}

Customer.prototype.formatCode = function(code) {
    return code.toLowerCase();
};

Customer.prototype.open = function(code) {
    try {
        this.data = new Api.Customer(JSON.parse(fs.readFileSync(paths.customers + this.formatCode(code) + '.json', 'utf8')));
        state.set('customer', this.formatCode(code));
    } catch (e) {
        this.data = new Api.Customer();
    }
};

Customer.prototype.save = function(callback) {
    writeDataSync(paths.customers + this.data.code.toLowerCase() + ".json", this.data, callback);
};
