note moritz <p>Sorry to the OP for going so far off-topic... <p>You need to grab a copy of the pugs repository. In that repo you'll find the directory <c>src/perl6/</c>, in which you can find <c>STD.pm</c> and <c>STD5_dump_match</c>. <p>(If you take somebody else's checkout of the pugs repository please copy the <c>perl6/</c> folder to your home directory, because you need write accessing for the lex cache). <p>In that dir, type <c>make</c>, then you can use <c>perl STD5_dump_match $file</c> to print out a match tree. <p>(You need a perl 5.10.0 in /usr/local/perl to run this, along with a few modules like [mod://re::engine::TRE], [mod://JSON::XS] and [mod://Moose]. I'll try to install all the dependencies on feather now.) 716367 716630
