Re: Help with %?RESOURCES variable

[Polgár Márton]

I mean, yes... the program runs at runtime. Anything available to the 
program is "available during runtime". Yes, you can look up the content 
at runtime - e.g from the place where it's installed. It is NOT advised 
to try and change the content that you can look up with %?RESOURCES - 
you aren't even supposed to know where it is; but as static data, you 
can always access it during runtime.


Regardless, what Brad Gilbert says seems to be consistent with what I 
can recall from a couple of months ago: it is only set in *modules* of a 
distribution. It can be set even if the module isn't precompiled but 
either way - it's not set in a mere raku script, even if it is located 
under the root folder of a distribution.

It contains a hash that provides compile and runtime access to

 The intent of that reads as - the value is set during compilation, 
and is available during runtime. Seems like either the doc is wrong, 
or the implementation is incomplete. I'm hoping that the doc is right, 
because it's useful to be able to read %?RESOURCES during runtime, and 
in general useful to set a variable once during compile, then read it 
forever at runtime.

yes, that was the case. It works inside a module. I guess i
have to
think differently on how to organize the code.

Unless things have changed since I was last active, only modules are
precompiled. `?` Twigilled variables are set at compile time.
So if it had any values, they wouldn't be useful, because they would be
created anew every time.
