- opt_parse(+OptsSpec, +ApplArgs, -Opts, -PositionalArgs, +ParseOptions) is det
- Parse the arguments Args (as list of atoms) according to OptsSpec.
Any runtime arguments (typically terminated by '--') are assumed to
be removed already.
Opts is a list of parsed options in the form Key(Value), or (with the option
functor(Func)
given) in the form Func(Key, Value). Dashed args not in OptsSpec are not permitted and will raise error (see tip on how to pass unknown flags in the module description). PositionalArgs are the remaining non-dashed args after each flag has taken its argument (filling intrue
orfalse
for booleans). There are no restrictions on non-dashed arguments and they may go anywhere (although it is good practice to put them last). ParseOptions are- output_functor(Func)
- Set the functor Func of the returned options Func(Key,Value). Default is the special value 'OPTION' (upper-case), which makes the returned options have form Key(Value).
- duplicated_flags(Keep)
- Controls how to handle options given more than once on the commad line.
Keep is one of
keepfirst, keeplast, keepall
with the obvious meaning. Default iskeeplast
. - allow_empty_flag_spec(Bool)
- If true (default), a flag specification is not required (it is allowed
that both shortflags and longflags be either [] or absent).
Flagless options cannot be manipulated from the command line
and will not show up in the generated help. This is useful when you
have (also) general configuration parameters in
your OptsSpec, especially if you think they one day might need to be
controlled externally. See example in the module overview.
allow_empty_flag_spec(false)
gives the more customary behaviour of raising error on empty flags.
