require('colors');

var bool = function(value){
// a boolean helper if a value is present
if (value === 'no' || value === 'false'){
return false;
}
if (value === 'yes' || value === 'true'){
return true;
}
return value;
};

// register full cmd line arg and aliases with some help text
clint.command('--auto', '-a', 'Watch for changes in less files, recompiles main', bool);
clint.command('--now', '-n', 'Do not keep running, instead - compile now and quit', bool);
clint.command('--no-compress', '-nc', 'Disable compression settings for less output, enabled by default, eg. ' + '--no-compress'.green + ' to disable', bool);

// register actual args
clint.command('--log', '-l', 'Set log level, eg. ' + '-l=3'.green);


var cliHelp = function(){
// uses command definitions from above
console.log(clint.help(2, ' : '.grey));
};

// now parser of args
var processArguments = function(args){
args = args || process.argv.splice(2);

var options = {
compress: true,
auto: false,
now: false,
log: 0
};

if (!args.length){
// call some cli helper.
return cliHelp();
}

clint.on('command', function(name, value){
switch (name){
case '--no-compress':
options.compress = false;
break;
case '--now':
options.now = true;
break;
case '--auto':
options.auto = true;
break;
case '--log':
options.log = Number(value);
}
});

clint.on('complete', function(){
runApp(options);
});

clint.parse(args);
};

processArguments();
