There's no built-in functionality to do what you want here. However, I have done a similar thing myself and I just load the file in, do a string replacement operation and then write it back out. This, by the way, is the way that laravel's own 'set application key' command works, so at least we aren't missing any undocumented functionality!

Something like this, in your command's fire method:

$dialog = $this->getHelperSet()->get('dialog');

$host = $dialog->ask($this->output, 'Hostname? ');
$db   = $dialog->ask($this->output, 'Database? ');
$user = $dialog->ask($this->output, 'Username? ');
$pass = $dialog->ask($this->output, 'Password? ');

if ($file = file_get_contents(app_path('config/database.php')) {
    $file = str_replace("'host'      => '*********'", "'host'      => '".$host."'", $file);
    $file = str_replace("'database'  => '********'", "'database'  => '".$db."'", $file);
    $file = str_replace("'username'  => '********'", "'username'  => '".$user."'", $file);
    $file = str_replace("'password'  => '*******'", "'password'  => '".$pass."'", $file);

    file_put_contents(app_path('config.database.php'));
}
