How do I convert integer to cardinal on the fly?

It should have been: my CArray[WCHAR] $lpData = CArray[WCHAR].new() JJ helped me find it on Stack Overflow.

Re: How to process command line options

Hello.
I'm following https://docs.raku.org/language/5to6-nutshell#Getopt::Long
but i still haven't figured it out how do i use a constraint in a
named parameter when processing a command line.
I have this piece of code:
multi sub MAIN("apt",
:$layout where $layout ~~
/^<[12345]>\+[kk|1]$|^6\+$|^[studio|unusual]$/ #= Apartment layout.
Values accepted: 1+kk,2+kk,...,5+kk, 6+, studio, unusual
) {
say "Enter";
}
however when i run it i get the --help message:
$ raku script.raku apt --layout '1+kk'
Usage:
script.raku [--layout=] apartment
--layout=Apartment layout. Values accepted:
1+kk,2+kk,...,5+kk, 6+, studio, unusual
If i make layout a positional parameter then it works correctly. Is
there a way to make this work with a named parameter?
And how do i make possible to use the "--layout" option several times?
Changing the parameter from $layout to @layout doesn't work.
Best regards,

Hi David,
This is probably not going to help, by maybe there
will be something in it that will help.

perl 6: How to parce values from the command line

If you are only interested in parameters with a single dash, you'll need
GetOpt::Long
Here is an example using Getopt::Long:
use v6;
use Getopt::Long;
my %opt = help => 0, 'r=s' => "", 'q=s' => "", "w=s" => "";
my %options = get-options(%opt).hash;
say %options;
Example run:
$ p.p6 -w xyz -q def -r abc
{help => 0, q => def, r => abc, w => xyz}
--
Here is an example using Getopt::Long:
use v6;
use Getopt::Long;
my %opt = help => 0, 'r=s' => "", 'q=s' => "", 'w=s' => "";
my %options = get-options(%opt).hash;
say %options;
say @*ARGS;
Example run:
$ p.p6 -w xyz -q def -r abc hello
{help => 0, q => def, r => abc, w => xyz}
[hello]
~
Use the MAIN sub:
#!/usr/bin/env raku
use v6;
sub MAIN(:$these ="These", :$are="Are", :$params="Params") {
say "$these $are $params";
}
You can type these parameters in any order:
./command-line.p6 --are=well --these=those
those well Params
And will also catch any extra parameter, showing you the actual parameters:
./command-line.p6 --are=well --these=those --not=this_one
Usage:
./command-line.p6 [--these=] [--are=] [--params=]

Re: How to process command line options
Thanks for the reply!
That was the issue, the missing '=', and the order. I thought that
because it was a named parameter the order wouldn't matter.
Regarding the second question, on how to have the same switch multiple
times, using a @ sigil doesn't work:
Code:
subset Layout of Str where * ~~ /^<[12345]>\+[kk|1]$|^6\+$|^[studio|unusual]$/;
multi sub MAIN("apt",
Layout :@layout! #= Apartment layout. Values accepted:
1+kk,2+kk,...,5+kk, 6+, studio, unusual
) {
say "enter!";
}
When invoking:
$> raku bin/script.raku --layout='unusual' --layout='1+kk' apt
Usage:
bin/script.raku --layout= ... apartment
--layout= ...Apartment layout. Values accepted:
1+kk,2+kk,...,5+kk, 6+, studio, unusual
Unfortunately I'm unable to find any example in google on how to do
this. I guess i will have to look for some module.

David Santiago

In that case, I can do basic build testing on MacOS for you. I would just try following the same instructions as Linux users more or less. -- Darren Duncan

Hi David,
The default parameter handling of Raku requires you to use an "=" sign
between the option name and value. Additionally, the option needs to be
before any positional arguments. Try running it as follows:
raku script.raku --layout='1+kk' apt
As for the ability to add it several times, I believe using an @ sigil
instead of a $ sigil should work, but perhaps someone else has spotted
an issue that I missed here.
