This library will always parse a program's command line arguments for Inputs. However, inputs can additionally be parsed from environment variables or default values, in that order of precedence. For example, if an input can be parsed from all of those places (command line argument, environment variable, and default value), all will be parsed, but the value from the command line will take precedence over the value from the environment variable, and the value from the environment variable will take precedence over the default value. Command line arguments are classified as one of the following: Command line arguments are parsed as options until a positional argument, subcommand, or an argument of just "--" is encountered. In other words, any options that belong to a command must come before any of that command's positional arguments or subcommands. Positional arguments and subcommands are mutually exclusive since allowing both to exist at once would invite unnecessary ambiguity when parsing because there's no reliable way to tell if an argument would be a positional argument or the name of a subcommand. Furthermore, positional arguments that are required must appear before any optional ones since it would be impossible to tell when parsing whether a positional argument is filling the spot of a required one or an optional one. Therefore, the format of a command is structured like this: There are only two types of options in terms of syntax: Non-boolean options must have a value attached. In other words, while options themselves can either be required or optional, there is no such thing as an option that may or may not have a value. Options can have appear in one of two forms and can have a name for each form: long or short. Typically an option's long name is more than one character, but an option's short name can only be a single character. Long form options are provided by prefixing the option's name with two hyphens ("--"), and they must appear one at a time, separately. Short form options are provided by prefixing the options short name with a single hyphen ("-"), and they can be "stacked", meaning under certain conditions, they can appear one after the other in the same command line argument. The following are some common ways of how options can be provided:
