Description :
*EXPERIMENTAL WORK*.
This module is similar to the Getopt::Long manpage, but with a rather
different interface. After experimenting with the Getopt::Long::Less
manpage and the Getopt::Long::EvenLess manpage (which offers interface
compatibility with Getopt::Long), I\'m now trying a different interface
which will enable me to \"clean up\" or do \"more advanced\" stuffs.
Here are the goals of Getopt::Panjang:
* * low startup overhead
Less than Getopt::Long, comparable to Getopt::Long::EvenLess.
* * feature parity with Getopt::Long::EvenLess
More features will be offered in the future.
* * more detailed error return
This is the main goal which motivates me to write Getopt::Panjang. In
Getopt::Long, if there is an error like an unknown option, or validation
error for an option\'s value, or missing option value, you only get a
string warning. Getopt::Panjang will instead return a data structure with
more details so you can know which option is missing the value, which
unknown option is specified by the user, etc. This will enable
scripts/frameworks to do something about it, e.g. suggest the correct
option when mistyped.
The interface differences with Getopt::Long:
* * There is only a single function, and no default exports
Getopt::Long has \'GetOptions\', \'GetOptionsFromArray\',
\'GetOptionsFromString\'. We only offer \'get_options\' which must be
exported explicitly.
* * capitalization of function names
Lowercase with underscores (\'get_options\') is used instead of camel case
(\'GetOptions\').
* * \'get_options\' accepts hash argument
This future-proofs the function when we want to add more configuration.
* * option handler also accepts hash argument
This future-proofs the handler when we want to give more arguments to the
handler.
* * There are no globals
Every configuration is specified through the \'get_options\' function. This
is cleaner.
* * \'get_options\' never dies, never prints warnings
It only returns the detailed error structure so you can do whatever about
it.
* * \'get_options\' never modifies argv/AATTARGV
Remaining argv after parsing is returned in the result metadata.
