The above worked fine on my W10 virtual machine

I am not seeing the above enter the proper syntax:

Where is the comma? How are the single quotes entered?
I don't understand what you are asking. The above checks whether
a directory exists and, depending on the result of this check, assigns
one of two values to a variable. I don't know what comma you are talking
about.
Wait, I think I got it. You're asking about the line underneath, the one
that you did not quote in this message, the line that says:
use lib $path;
"use lib" expects you to pass a string (or more strings). 'c:/NtUtil' is
a string. $path is a variable that holds a string. "use lib $path"
calls "use lib" and passes to it the string in the variable $path.
So to be a bit more clear, in your case you have a path that you always
need to pass ('c:/something') and another one that you want to pass only
if it exists. OK, so maybe something like:
my @path;
BEGIN {
for ('K:/NtUtil', 'X:/NtUtil') -> $candidate {
push @path, $candidate if $candidate.IO.d;
}
push @path, 'C:/NtUtil';
}
use lib @path;
Maybe something like that will work for you.
G'luck,

Ah, but of course. Aren't Web standards and browsers great. I did copy
and paste it from the location bar, and I did not stop to think about
it, since I foolishly trusted that my browser would actually copy
a usable URL.
Thanks.

Hi Peter,
I am so use to
BEGIN

In other languages, that I had to ask. Modula2
is especially a BEGIN and END user.
I do adore the way Raku cleans up the unnesseary

But I still do catch myself saying "DO" when I

Well, there is an opening { after "BEGIN", so, yes.
More precisely, it closes the block that is to be executed early.

"use lib" is evaluated quite early in the program's execution, so to do
any interesting things with it, you will need to use a BEGIN phaser
(similar to what you might know as a BEGIN block in Perl):
=
#!/usr/bin/env raku
use v6.d;
my $path;
BEGIN {
$path = 'lib1'.IO.d ?? 'lib1' !! 'lib2';
}
use lib $path;
use Foo;
Foo.new.hello;

Can I have several "use lib" statements use lib 'C:\NtUtil", "."; use lib 'K:\NtUtil'; # if directory does not exist to use with the "if" statement?
Re: Is thre a way to do an "if" on "use lib"?
No, there's no else. This if is for using modules with different names. If you want to use modules in different paths, it's probably not a good idea to call them by the same name. You can call them different names (and do a use lib on all paths), or use other mechanisms to differentiate them, such as the :api module metadata Check everything about that here: https://docs.raku.org/language/typesystem#Versioning,_authorship,_and_API_version .

Unsurprisingly, there is "if": https://github.com/FROGGS/p6-if Install it with zef install if And then... use if; # activate the :if adverb on use statements use My::Linux::Backend:if($*KERNEL.name eq 'linux');use My::Fallback::Backend:if($*KERNEL.name ne 'linux'); El dom., 7 jun. 2020 a las 9:29, ToddAndMargo via perl6-users (< perl6-us...@perl.org>) escribió: > Hi All, > > Is there a way to do an "if" on "use lib", so > I do not have to keep commenting these back and forth? > > # use lib 'C:/NtUtil', '.'; > use lib 'C:/NtUtil', '.', 'K:/NtUtil'; > > Many thanks, > -T > -- JJ
