NAME Perlito5 - a Perl5 compiler SYNOPSIS use Perlito5::Compiler; use Perlito5::JavaScript2::Emitter; use Perlito5::JavaScript2::Runtime; use Data::Dumper; my $perl5_source = ' print "hello, World!\n" '; $Perlito5::PKG_NAME = 'main'; $Perlito5::PROTO = {}; my $ast = Perlito5::Grammar::exp_stmts($perl5_source, 0); print "Syntax Tree:\n"; print Dumper Perlito5::Match::flat($ast); my $js_source = Perlito5::AST::CompUnit::emit_javascript2_program([ Perlito5::AST::CompUnit->new( name => 'main', body => Perlito5::Match::flat($ast) ) ]); print "JavaScript source code:\n"; print $js_source; # in the command line: perlito5 --help perlito5 -Cjs perlito5 -Cjava DESCRIPTION This program reads Perl5 source code and generates native code. The compiler options are available with the command: perlito5 -h COOKBOOK Obtaining a "perlito5.js" script that executes in the "node.js" JavaScript compiler # Step 1: use perlito5 to compile perlito5 to JavaScript. perlito5 --bootstrapping -Cjs `which perlito5` > perlito5.js # Step 2: ensure that PERL5LIB points to the directory where is installed. echo $PERL5LIB # Step 3: set PERL5LIB if needed. perldoc -l Perlito5 # /usr/local/lib/perl5/site_perl/5.20.1/ export PERL5LIB=/usr/local/lib/perl5/site_perl/5.20.1 # Step 4: install nodejs if needed. # Step 5: this should work now: nodejs perlito5.js -e ' print "hello, World!\n" ' # hello, World! Obtaining a Perl compiler script that runs in the browser # Step 1: create a Perl script that loads the compiler and evaluates a string. # Save this to "": use Perlito5::Compiler; use Perlito5::JavaScript2::Emitter; use Perlito5::JavaScript2::Runtime; sub eval_perl5 { eval "$_[0]; 1" or warn "Perl error: $@"; } # Step 2: use perlito5 to compile your "" script to JavaScript. perlito5 --bootstrapping -Cjs > perlito5-browser.js # Step 3: load the compiler in the browser; # compile perl5 to javascript; # eval() the javascript code. # Note: the default implementation for "print" will invoke console.log(); # you can override this by redefining p5pkg['Perlito5::IO'].print() AUTHORS Flavio Soibelmann Glock .
