FUNCTIONS
None are exported by default, but they are exportable.
convert_args_to_array(%args) -> [STATUS_CODE, ERR_MSG, RESULT]
Convert hash arguments to array.
Using information in sub spec's ~args~ clause (particularly the ~arg_pos~ and ~arg_greedy~ arg type clauses), convert hash arguments to array.
Example:
: my $spec = { : summary => 'Multiply 2 numbers (a & b)', : args_as => 'array', args => { : a => ['num*' => {arg_pos=>0}], : b => ['num*' => {arg_pos=>1}], : } : }
then ~convert_args_to_array(args=>{a=>2, b=>3}, spec=>$spec)~ will produce:
: [200, "OK", [2, 3]]
Returns a 3-element arrayref. STATUS_CODE is 200 on success, or an error code between 3xx-5xx (just like in HTTP). ERR_MSG is a string containing error message, RESULT is the actual result.
Arguments (* denotes required arguments):
args* => hash
spec* => hash
