var argsv = new ArgsParser();

// Retrieve an array of command-line arguments and its values
console.log("\nCommand line arguments: " + JSON.stringify(argsv.parseArgs("=")));

// Get value of a single command-line argument by its name
console.log("\nParam: { \"hello\" } Value: {\"" + argsv.getParam("hello") + "\"}");

Constructor

.ArgvParser #####.ArgvParser() ArgvParser - constructs a command-line arguments parser object,

Methods

.parseArgs( delimiter = 0 )

parses the command-line and returns an associative array of arguments and its values separated by a delimiter.

Warning: The using of all other ArgvParser object's methods is only possible after calling parseArgs method.

.getParam( param )

returns a value of an argument with a specific param name. If an argument with the given name does not exists, this method will return {Not_Found}, and {Not_Set}, in case when the value of an argument is missing.

.isSet( param )

performs a verification whether a value of an argument with the given name is set. This method can only be used when the command-line contains at least one argument which pair of its name and value are separated by the delimiter (e.g. mode='open'). This method returns true if the value of an argument is set and false unless otherwise.
