getoptions

Overview ¶

command-line options processing

Parses options of the forms:

-option               - increment otion count
-option=value         - set value
--option              - increment option count
--option=value        - set value
--                    - stop option parsing

Note:

Does not support combined single letter options e.g. -vvv is the same as --vvv
and is the separate option "vvv".
Repeated options cause the value string to be appended to the options map item.
Options with no value append the empty string, e.g. "-v -v -v" would make len(options["v"]) == 3.

Alias table:

This allows the option to be aliased e.g. -v -> --verbose

Returns:

program_name          - string
options               - map["option"]=[]string{"value1","value2"}
arguments             - []string  (all options not starting with "-" and everything after --)
