MoarVM (short for Metamodel On A Runtime Virtual Machine) is a runtime built for the 6model object system. It is primarily aimed at running NQP and Rakudo Perl 6, but should be able to serve as a backend for any compilers built using the NQP compiler toolchain.
Building the VM itself takes just:
perl Configure.pl make
nmake on Windows). Currently it is known to build on Windows with MSVC,
clang on Linux & MacOS X. We're expanding this with time.
perl Configure.pl --help to see the configure-time options, as well
as some descriptions of the make-time options/targets.
Building an NQP with MoarVM
After installing MoarVM, you can clone the NQP repository or grab a source tarball and use the Configure.pl script in it like so:
perl Configure.pl --backend=moar --prefix=where_your_moarvm_install_lives
Alternatively, the same Configure.pl script in NQP is able to clone, build
and install a copy of MoarVM on its own if you supply the
Building a Rakudo with MoarVM
When pointing the
Configure.pl script in rakudo's repository at a
that has an
nqp-m installed in it, it will automatically detect and configure
the MoarVM backend. Alternatively,
--backend=moar,parrot can be used to force
it to build the MoarVM and Parrot backends, for example. Just like in the NQP
Configure.pl script, you have the option to supply a
--gen-moar flag that
will do all the work for you, including creating an
MoarVM is currently in development. It can run all of the NQP test suite, all of the Rakudo sanity tests, and >99% of the spectests that the current leading Rakudo backend (the JVM) can.
Unlike the JVM backend of NQP, the MoarVM repo is not currently planned to be
integrated into the main NQP source repo http://github.com/perl6/nqp but
instead can be pulled in by
Configure.pl --gen-moar configure script in the
NQP repo, same as it can
Some key features provided by MoarVM include:
- Meta-object programming, using the 6model design
- Precise, generational GC
- Unicode support
- First-class code objects, lexical variables and closures
- Bounded serialization
- Code generation from MAST (MoarVM AST)
- Runtime loading of code
- Big integers
- A range of IO and process support
- Basic threads
