class Cling::Argument

• Cling::Argument
• Reference
• Object

Overview

Represents a command line argument, this can be a single value or a string value. Arguments are parsed after the main command and any subcommands are resolved. Note that Options that have values take priority in the resolution list, so the following example would only yield 2 arguments:

./greet --time=day Dev
#              ^^^
# belongs to the flag option

Arguments should typically be defined in the Command#setup method of a command using Command#add_argument to prevent conflicts.
