NAME ^

punie -- A compiler for Perl 1

SYNOPSIS ^

  $ ./parrot languages/punie/punie.pir script.p1

DESCRIPTION ^

Punie is a compiler for Perl version 1, running on Parrot. Its parser is a PGE grammar (a subclass of PGE::Grammar). The compilation is a series of tree transformations using TGE: from match tree to abstract syntax tree (AST), from AST to opcode syntax tree (OST), and finally from OST to bytecode (actually to PIR, at first). For more on the ideas behind the compiler, see:

http://svn.lohutok.net/nam/trunk/parrot/docs/compiler_tools.pod

So far, Punie handles constants (strings, integers, floats), print statements, conditionals, do blocks, comma lists, and some basic math and logic ops.

  print 1;
  print 45.5;
  print "ok 1\n";
  print 1 + 2, "\n", 2 + 3, "\n";
  unless (1 - 1) {
    print "a sum of nothing\n";
  }
