如何知道我正在运行的perl6/rakudo的版本？

Question

尝试-v开关,我得到了鹦鹉svn版本:

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

但我怎么知道rakudo版本,a vx.xx或{some-git-hash}？

谢谢,

Answer 1

目前你不能知道:(

在RT中有一个补丁,等待审查:http://rt.perl.org/rt3/Ticket/Display.html？id = 73148但到目前为止还没有应用.

更新:有了足够新的Rakudo,你得到:

$ perl6 -v

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

"版本"之后的东西是git describe输出.
