Rakudo Perl 6 This is Rakudo Perl, a Perl 6 compiler for the Parrot virtual machine. Rakudo Perl is Copyright (C) 2008-2010, The Perl Foundation. Rakudo Perl is distributed under the terms of the Artistic License 2.0. For more details, see the full text of the license in the file LICENSE. 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 from http://github.com/rakudo/star/downloads . Build requirements (Installing from source) For building Rakudo you need at least a C compiler, a "make" utility, and Perl 5.8 or newer. To automatically obtain and build Parrot or the spectest suite you may also need a subversion (svn) client. In order to fully support Unicode, you'll also want to have the ICU library installed (<http://site.icu-project.org/>). Rakudo can run without ICU, but some Unicode-related features do not work properly. As an example, on Debian GNU/Linux or Ubuntu Linux, the necessary components for building Rakudo can be installed via the command aptitude install build-essential libicu-dev subversion (Perl is installed by default already). To enable parallel testing you also need the CPAN module Test::Harness in version 3.16 or newer; you can control the number of parallel jobs with the "TEST_JOBS" environment variable. Building and invoking Rakudo Because Rakudo is under rapid development, we generally recommend downloading Rakudo directly from github and building from there: $ git clone git://github.com/rakudo/rakudo.git If you don't have git installed, you can get a tarball or zip of Rakudo from <http://github.com/rakudo/rakudo/downloads>. Then unpack the tarball or zip. If you already have cloned Rakudo from github, you can get (pull) the most recent version from github like this: $ cd rakudo $ git pull Once you have an updated copy of Rakudo, build it as follows: $ cd rakudo $ perl Configure.pl --gen-parrot $ make This will create a "perl6" or "perl6.exe" executable in the current (rakudo) directory. Note that if you have multiple (Perl 5) "perl"s in your path, you may need to use a fully qualified path to the appropriate executable (or update your PATH environment variable). Programs can then be run from the build directory using a command like: $ ./perl6 hello.pl Important: To run Rakudo from outside the build directory, you must run $ make install This will install the "perl6" (or "perl6.exe" binary on windows) into the "parrot_install/bin" directory locally, no additional root privileges necessary. The "--gen-parrot" above option tells Configure.pl to automatically download and build the most appropriate version of Parrot into a local "parrot/" subdirectory, install that Parrot into the "parrot_install/" subdirectory, and use that for building Rakudo. It's okay to use the "--gen-parrot" option on later invocations of Configure.pl; the configure system will re-build Parrot only if a newer version is needed for whatever version of Rakudo you're working with. You can use "--parrot-config=/path/to/parrot_config" instead of "--gen-parrot" to use an already installed Parrot for building Rakudo. This installed Parrot must include its development environment; typically this is done via Parrot's "make install" target or by installing prebuilt "parrot-devel" and/or "libparrot-dev" packages. The version of the already installed Parrot must satisfy a minimum specified by the Rakudo being built -- Configure.pl will verify this for you. Released versions of Rakudo always build against the latest release of Parrot; checkouts of the HEAD revision from github often require a version of Parrot that is newer than the most recent Parrot monthly release. Once built, Rakudo's "make install" target will install Rakudo and its libraries into the Parrot installation that was used to create it. Until this step is performed, the "perl6" executable created by "make" above can only be reliably run from the root of Rakudo's build directory. After "make install" is performed, the installed executable can be run from any directory (as long as the Parrot installation that was used to create it remains intact). If the Rakudo compiler is invoked without an explicit script to run, it enters a small interactive mode that allows Perl 6 statements to be executed from the command line. Build/install problems Occasionally, there may be problems when building/installing Rakudo. Make sure you have a backup of any custom changes you have done to the source tree before performing the following steps: Try to remove the "parrot_install" subdirectory: $ cd rakudo $ rm -r parrot_install $ git pull $ perl Configure.pl --gen-parrot $ make Or, in case you are really stuck, start with a fresh source tree: $ rm -r rakudo $ git clone git://github.com/rakudo/rakudo.git Running the test suite Entering "make test" will run a small test suite that comes bundled with Rakudo. This is a simple suite of tests, designed to make sure that the Rakudo compiler is basically working and that it's capable of running a simple test harness. Running "make spectest" will import the official Perl 6 test suite from the Pugs repository <http://svn.pugscode.org/pugs/t/spec/> and run all of these tests that are currently known to pass. If you want to automatically submit the results of your spectest run to a central server, use "make spectest_smolder" instead. You need the Perl 5 module TAP::Harness::Archive and an active internet connection for that. The smoke results are collected at <http://smolder.plusthree.com/app/public_projects/details/18>. At present we do not have any plans to directly store the official test suite as part of the Rakudo/Parrot repository, but will continue to fetch it from the Pugs repository. You can also use "make" to run an individual test from the command line: $ make t/spec/S29-str/ucfirst.t t/spec/S29-str/ucfirst.rakudo .. 1..4 ok 1 - simple ok 2 - empty string ok 3 - # SKIP unicode ok 4 - # SKIP unicode # FUDGED! ok All tests successful. Files=1, Tests=4, 1 wallclock secs ( 0.02 usr 0.00 sys + 0.57 cusr 0.06 csys = 0.65 CPU) Result: PASS If you want to run the tests in parallel, you need to install a fairly recent version of the Perl 5 module Test::Harness (3.16 works for sure). 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 on Parrot. Figuring out the right one to use is often the biggest battle. Here are some rough guidelines: If you have a question about Perl 6 syntax or the right way to approach a problem using Perl 6, you probably want the "firstname.lastname@example.org" mailing list. This list is primarily for the people who want to *use* Perl 6 to write programs, as opposed to those who are implementing or developing the Perl 6 language itself. Questions about the Rakudo compiler for Parrot and the Parrot compiler tools can go to "email@example.com". Discussion about Parrot itself generally takes place on "firstname.lastname@example.org". The Rakudo and Parrot development teams tend to hang out on IRC a fair bit, either on "irc.freenode.net/#perl6" or "irc.perl.org/#parrot". Rakudo's official web site is <http://rakudo.org/>, where you can find useful information for developers and users alike. There's also a Parrot blog at <http://parrotblog.org/>, most Perl 6 related news is assembled at <http://planetsix.perl.org/>. Links to many other resources can be found on <http://perl6.org/>. Reporting bugs Bug reports should be sent to "email@example.com" with the moniker [BUG] (including the brackets) at the start of the subject so that it gets appropriately tagged in the RT system (https://rt.perl.org/rt3/). 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. Submitting patches If you have a patch that fixes a bug or adds a new feature, please submit it to "firstname.lastname@example.org" with the moniker [PATCH] (including the brackets) at the start of the subject line. We'll generally accept patches in any form if we can get them to work, but unified diff from the "git" command is greatly preferred. In general this means that in the "rakudo" directory you make your changes, and then type git commit -m 'Your commit message' changed/filename.pm git format-patch HEAD^ This will generate a file called "001-your-commit-message.patch", or more of them if you made multiple commits; please attach these to your email. (Note to the maintainers: you can apply these patches with the "git-am -s" command; it preserves meta information like author). Other ways to create and submit patches are discussed here: <http://wiki.github.com/rakudo/rakudo/steps-to-create-a-patch>. How the compiler works See docs/compiler_overview.pod.
