How to know the version of perl6/rakudo I am running?

Question

Trying the -v switch, I get the parrot svn revision:

$ perl6 -v
This compiler is built with the Parrot Compiler Toolkit, parrot revision 45822.

but how do I know the rakudo version, either a vx.xx or {some-git-hash}?

Thanks,

Answer 1

Currently you can't know :(

There's a patch for that in RT that awaits review: http://rt.perl.org/rt3/Ticket/Display.html?id=73148 but so far it hasn't been applied yet.

Update: With a sufficiently new Rakudo, you get:

$ perl6 -v

This is Rakudo Perl 6, version 2010.06-212-g1086ff8

Where the thing after "version" is the git describe output.

Answer 2

perl6 -v now works. It provides the last monthly release, the number of commits since then, and the git hash.
