Well he is me so let my try and explain. The idea is to be able to simply assign Env vars to variables so for example you might do use Trait::Env; my $windir is env; And then $windir should be assigned the value of the %*ENV variable at runtime. There's a bunch of other stuff in it too, it's mostly intended to make Docker environment setup easy to use but should be useful in other areas.

Re: How to read a particular environmental variable?
You might want to take a look at Trait::Env, partly because I've not tested it in Windows and I'd be interested to know if it works well.

Of course %*ENV is case sensitive, hashes are case sensitive. say %*ENV.^name; # Hash %*ENV gets populated with the values before your code runs. Other than that it is fairly ordinary.

It’s still a hash — the * twigil tweaks it’s scope, but it is still a % — so %*ENV works (windows) On Tue, Apr 7, 2020 at 6:48 PM ToddAndMargo via perl6-users < perl6-users@perl.org> wrote: > Hi All, > > $ raku -e 'say %*ENV;' > > Gives me ALL of them.

How to read a particular environmental variable?
Hi All, $ raku -e 'say %*ENV;' Gives me ALL of them. Is there a way to just ask for a particular one, such as %appdata%, or %userprofile% in Windows or $HOME is Linux? Many thanks, -T
