Re: Version of a Module

[Lloyd Fournier]

It is a bug. It's because of the way require is implemented at the moment
is a little rough. The first one is asking for the .^ver of a stub package
require has inserted. ::("Bailador").ver should work.

Re: Version of a Module

[Martin Barth]

yap, when mi6 updates your META6.json this makes sense to me as well.

This leads me to another question

Can zef/perl6 handle differend modules version based on the suffix 
':ve<0.0.1>' or based on the META6.json. I mean, could there be 2 
scripts each using a different version of my module withouth having this 
suffix in it?

Isn’t that info available in %?RESOURCES somewhere ??

See I'm using mi6 to generate my META6.json file from the report and it
picks the version up from the module file. Other options like that seem

Hello,

but your approach means you have to state the version in the META6.json 
AND in the Module.pm6 file again. This would be the similar to having 
$VERSION in perl5. Shouldnt there be a simpler way?

Hi Martin,

AFAIK you can only do this with hacks atm. It's different if the module is
installed or if you are in the source directory doing pelr6 -Ilib.

I do this in my own module here:

Version of a Module

[Martin Barth]

Hello everyone,

I wanted to repeat the question that I asked today on #perl6.
I am looking for a way to retrieve the version of a Perl6-Module from 
within the module itself.


 there is often a our $VERSION in perl5 modules. is this still 
idiomatic/a good way to go in perl6
 i think the version is meant to be part of the meta info and 
such?
 but that means the module itself does not know about its 
version, just e.g. zef does?
 i'm convinced there ought to be a way to get the full meta 
info from whatever installation your script was grabbed from

 but i don't know what or how
