Play with Perl6 on Mac OS X Leopard

January 8, 2008

Perl6 hasn't been released yet, but you can play with it all the same. It's a very interesting piece of work and I recommend you check it out, even if you're like me and don't do much Perl.

First checkout the latest Parrot source code using Subversion:

svn co https://svn.perl.org/parrot/trunk parrot

Run the configure script, then compile Parrot using make:

perl Configure.pl
make

Optionally you can run the test suite.

make test

[...]

All tests successful (1 subtest UNEXPECTEDLY SUCCEEDED), 14 tests and 616 subtests skipped.
Files=546, Tests=10726, 747 wallclock secs (502.84 cusr + 78.73 csys = 581.57 CPU)

"1 subtest UNEXPECTEDLY SUCCEEDED" What?!?! Hehe.. You gotta love those tests, passing even when they're not supposed to.

Then finally you can build the perl6 binary:

make perl6

Hopefully you got no errors. Copy the binary somewhere into your path:

cp languages/perl6/perl6 ~/bin

Run a test script:

#!/usr/bin/env perl6

print "hello perl6!";

Outputs:

hello perl6!

Book Recommendation:

C++: The Complete Reference covers everything from keywords, syntax, and libraries, to advanced features such as overloading, inheritance, virtual functions, namespaces, templates, and run-time type identification, plus there's a complete description of the Standard Template Library (STL). I found the book incredibly useful even when making really complicated programs because of the fact that it has everything in it. I can't really stress that point enough. Seriously, if you're getting a C++ book you are planning on actually using, you really should get this book.
