I want to use Raku Modules to group some functions, I often use. Because these functions are all loosely coupled, I don't like to add them in a class.
I like the idea of use
, where you can select, which functions should be imported, but I don't like it, that the functions, which are imported are then stored in the global namespace.
For example if I have a file my_util.pm6
:
#content of my_util.pm6
unit module my_util;
our sub greet($who) is export(:greet) {
say $who;
}
sub greet2($who) is export(:greet2) {
say $who;
}
sub greet3($who) is export(:greet3) {
say $who;
}
and a file test.p6
:
#!/usr/bin/perl6
#content of test.p6
use v6.c;
use lib '.';
use my_util :greet2;
greet("Bob"); #should not work (because no namespace given) and also doesn't work
greet2("Bob"); #should not work (because no namespace given) but actually works
greet3("Bob"); #should not work (because no namespace given) and also doesn't work
my_util::greet("Alice"); #works, but should not work (because it is not imported)
my_util::greet2("Alice"); #should work, but doesn't work
my_util::greet3("Alice"); #should not work (because it is not imported) and also doesn't work
I would like to call all functions via my_util::greet()
and not via greet()
only.
The function greet()
defined in my_util.pm6
comes very close to my requirements, but because it is defined as our, it is always imported. What I like is the possibility, to select which functions should be imported and it should be possible to leave it in the namespace defined by the module (i.e. it doesn't pollute the global namespace)
Does anyone know, how I can achieve this?
