The command-line.parser vocabulary can be used to parse command-line arguments.
A sequence of option instances is used to control how the arguments are parsed and is typically passed to the following words from a command-line program:
Some variables control certain aspects of the parsing:
In the case that you want to pass an option lookalike as a positional argument, for example --foo then you can pass it after -- to indicate that the remaining arguments should be interpreted as positional arguments.
Sub-commands are supported using the with-commands word.
A sequence of option instances is used to control how the arguments are parsed and is typically passed to the following words from a command-line program:
with-options ( ... options quot: ( ... -- ... ) -- ... )
parse-options ( options -- arguments )
Some variables control certain aspects of the parsing:
| default-help? | A boolean value controlling if a --help option is added. |
| allow-abbrev? | A boolean value controlling if abbreviations are allowed for options. |
| program-name | An optional program name, or it will be inferred from the script or launched binary name. |
| program-prolog | Some text to include in the help display before the options. |
| program-epilog | Some text to include in the help display after the options. |
