Rakudo Perl 6
This is Rakudo Perl, a Perl 6 compiler for the MoarVM and JVM.

This directory contains only the Rakudo Perl 6 compiler itself; it does not contain any of the modules, documentation, or other items that would normally come with a full Perl 6 distribution. If you're after more than just the bare compiler, please download the latest Rakudo Star package.
Note that different backends implement slightly different sets of features. For a high-level overview of implemented and missing features, please visit the features page on perl6.org.

Building and Installing Rakudo
See the INSTALL.txt file for detailed prerequisites and build and installation instructions.
The general process for building is running
perl Configure.pl with
the desired configuration options (common options listed below), and
make install. Optionally, you may run
make spectest to test your build on Roast,
the Official Perl 6 test suite.
Installation of Rakudo simply requires building and running
Note that this step is necessary for running Rakudo from outside the build
directory. But don't worry, it installs locally by default, so you don't need
any administrator privileges for carrying out this step.
Configuring Rakudo to run on MoarVM
To automatically download and build a fresh MoarVM and NQP, run:
perl Configure.pl --gen-moar --gen-nqp --backends=moar
Configuring Rakudo to run on the JVM
Note that to run Rakudo on JVM, JDK 1.7 must be installed. To automatically download an build a fresh NQP, run:
perl Configure.pl --gen-nqp --backends=jvm
If you get an out of memory error building rakudo on the JVM, you may
need to modify your NQP runner to limit memory use. e.g. edit the
nqp-j / nqp-j.bat executable (found wherever you installed to, or in the
install/bin directory) to include
-Xms500m -Xmx2g as options passed to java.
Multiple backends at the same time
By supplying combinations of backends to the
--backends flag, you
can get two or three backends built in the same prefix. The first
backend you supply in the list is the one that gets the
as a symlink, and all backends are installed seperately as
perl6-j for Rakudo on
MoarVM, or JVM respectively.
The format for the
--backends flag is:
$ perl Configure.pl --backends=moar,jvm $ perl Configure.pl --backends=ALL
Where to get help or answers to questions
There are several mailing lists, IRC channels, and wikis available with help for Perl 6 and Rakudo. Figuring out the right one to use is often the biggest battle. Here are some rough guidelines:
The central hub for Perl 6 information is perl6.org. This is always a good starting point.
If you have a question about Perl 6 syntax or the right way to approach a problem using Perl 6, you probably want the "email@example.com" mailing list or the "irc.freenode.net/#perl6" channel. The perl6-users list is primarily for the people who want to use Perl 6 to write programs, so newbie questions are welcomed there. Newbie questions are also welcome on the #perl6 channel; the Rakudo and Perl 6 development teams tend to hang out there and are generally glad to help. You can follow "@rakudoperl" on Twitter, and there's a Perl 6 news aggregator at Planet Perl 6.
Questions about NQP can also be posted to the #perl6 IRC channel. For questions about MoarVM, you can join #moarvm on freenode.
Bug reports should be sent to "firstname.lastname@example.org", which will
automatically create a ticket in
the RT system.
Please include or attach any sample source code that exhibits the bug,
and include either the release name/date or the git commit identifier.
You find that information in the output from
perl6 --version (or in
the first line of
git log, if Rakudo fails to build). There's no need
to cc: the perl6-compiler mailing list, as the RT system will handle
this on its own. Please start your subject with one (or more) of the
following text, including the brackets:
- [BUG] - this is an actual bug
- [LTA] - a "Less Than Awesome" diagnostic or warning is being generated
- [JVM] - issue only occurs on the JVM
- [PERF] - any performance related issue
- [UNI] - related to unicode support
- [@LARRY] - this ticket requires a decision from the design team
If you find a bug in MoarVM or NQP, you can either discuss it on the IRC and have it reported for you, or you can submit an issue to the issue trackers on github for perl6/nqp or moarvm/moarvm.
If you have a patch that fixes a bug or adds a new feature, please create a pull request using github's pull request infrastructure.
Please separate your commits for different issues into different branches, and please squash out any intermediate commits, like adding/removing debug output.
Line editing and tab completion
If you would like simple history and tab completion in the perl6 executable, you need to install the Linenoise module. The recommended way to install Linenoise is via panda:
panda install Linenoise
An alternative is to use a third-party program such as rlwrap.
