007

007 is a small language created as a testbed for Perl 6 macros. Its goal as a language is to inform the implementation of macros in Perl 6, by means of being a faster-moving code base and easier to iterate on towards good solutions.

Rakudo already contains a rudimentary implementation of macros, but at this point the most mature macro implementation for Perl 6 is embodied in 007.

The name "007" was chosen because the data type representing program fragments is called Q.

Get it

You need to have Rakudo Perl 6 installed and in your path.

Then, clone the 007 repository. (This step requires Git. There's also a zip file.)

$ git clone https://github.com/masak/007.git
[...]

Run it

Set the PERL6LIB environment variable:

$ cd 007
$ export PERL6LIB=$(pwd)/lib

Now this should work:

$ bin/007 -e='say("OH HAI")'
OH HAI

$ bin/007 examples/format.007
abracadabra
foo{1}bar

Status

007 is currently in development.

The explicit goal is to reach some level of feature completeness for macros in 007, and then to backport that solution to Rakudo.
