• Posted Trying out AWK in Java with Perlito5 to Flávio S. Glock

  I’ve got this example “awk” script:

  $ cat x.awk 
  BEGIN { print "Month Crates"
      print "----- ------" }
      { print $1, " ", $2 }
  

  we can convert AWK to Perl with “a2p”:

• Posted Perl5 to Java compiler - week 100 - bootstrapping to Flávio S. Glock

  It's been a 100 weeks since the Perl5 to Java compiler started.

  The compiler is now "good enough" to translate itself to Java.

  $ git clone git@github.com:fglock/Perlito.git ; cd Perlito
  
  $ make clean
  
  # create the "perlito5.j…

• Posted specifying primitive data types in Perlito5 to Flávio S. Glock

  I'm trying out this new little benchmark, which imports Java primitive data types into a Perl script:

  # misc/benchmark/benchmark_typed_primitive.pl
  package long {}
  my long $count = 0;
  my long $i = 0;
  while ( $i < 400 ) {
      my long $j = 0;
      while ( $j <…

• Posted Perl5 to Java compiler - using a Perl module from Java to Flávio S. Glock

  Perlito5 now supports calling Perl subroutines from Java.

  For example, a Perl module was compiled to "Main.java", and it can be called using:

   class TestPerl {
      public static void main(String[] args) throws Exception {
          // initialize the Perl m…

• Posted Perl5 to Java compiler - first little script to Flávio S. Glock

  For the first time, Perlito5-Java can now run an unmodified script - "rc-forest-fire" from the perl6-bench project.

  I've experimented running the benchmark on the several Perlito5 platforms, and on perl its…

• Posted Perl5 to Java compiler - integrating with java.lang.Thread to Flávio S. Glock

  Here is another experiment with calling Java libraries from Perlito5-Java; using JVM threads:

  package Java::Thread {
      import => "java.lang.Thread"
  };
  
  my Java::Thread $thread1 = new Java::Thread(
      sub {
          for my $i (0..10) {
              print "thr…

• Posted Perl5 to Java compiler - integrating with Rhino to Flávio S. Glock

  I'm experimenting with calling Java libraries from Perlito5-Java; calling into the JVM Javascript engine was pretty easy:

  # here we import the Java packages into Perl packages:

      import => "javax.script.ScriptEngineManager"
  };

• Posted a perl5 to Java compiler - work in progress to Flávio S. Glock

  I've been adding support for Java in Perlito5 in the last few days.

  This is what it does so far:

• Posted a perl5 to perl6 translator - update to Flávio S. Glock

  I've moved the "perlito" perl5 to perl6 compiler to a new home:
  

  There are minor improvements in the compiler since last post, such as:

• Posted a perl5 to perl6 translator to Flávio S. Glock

  The "perlito" perl5 to perl6 compiler is online at: http://perlcabal.org/~fglock/perlito5to6.html.

  It is also available as an irc bot for snippets and as a command…

• Posted formats added to perlito5 to Flávio S. Glock

  perlito5 is a Perl compiler written in Perl.

  The format statement was required in the grammar for completeness. The 'format' command is not supported at the emitter side - it compiles, but it doesn't run yet.

  Some other features are still marked as TODO and are simple to implement:…

• Posted indirect-object added to perlito5 to Flávio S. Glock

  perlito5 is a Perl compiler written in Perl.

  The tests* for indirect-object and bareword disambiguation can be run online at http://perlcabal.org/~fglock/perlito5.html (you need to copy-paste the tests, it is not automated).

• Posted tie() in perlito5 to Flávio S. Glock

  I've just added a small tie() example to the perlito5-in-the-browser page.

  This was implemented today, and it only supports a few methods for now.

  tie() does not make perlito5 any slower - the tied containers use a separate c…

• Commented on Perl courseware for the web using client-side perl
  Joel: I didn't know about perltuts.com - it looks really good, thanks for pointing out....
• Posted Perl courseware for the web using client-side perl to Flávio S. Glock

  This is an idea I've discussed with Gabor (szabgab++) during the last conferences - we could use perlito as a tool to write educational pages about perl, that would embed executable code that can be modified by the reader.

  There is a possible alternate impl…

• Posted Playing with Perl5 syntax to Flávio S. Glock

  At some point in YAPC::Europe I was showing the perlito5 compiler to stevan++, and we discussed how it could be used to prototype grammar extensions to Perl5.

  Perlito grammar is mostly written in simple perl, without extensions (in some places there are still remains of the original perl6 …

• Posted Perl in small devices to Flávio S. Glock

  I’ve participated in some discussions about running perl on small devices during the Perl Reunification Summit and YAPC::Europe.

  The targets would be java/dalvik, objective-c/ios, and arduino. There is some work going on by Martin Berends (mberends++) on arduino, and Claes Jakobsson …

• Posted Implementing Perl6 eval($str, :lang<perl5>) to Flávio S. Glock

  Moritz++ helped me implement a proof of concept eval-perl5 that works in rakudo, and uses Perlito5 (a perl5 compiler written in perl5).

  This snippet could be used to implement a perl5 compatibility layer that works both in rakudo and niecza (and maybe pugs).

  Perlito5 -Cperl6

• Posted running perl with -MO=Deparse in node.js to Flávio S. Glock

  I've hacked a '-MO=Deparse' option to perlito5. Now I can check the parser by comparing the output with perl:

  $ node perlito5.js -Isrc5/lib -MO=Deparse -e ' ${ xxx{zzz}[3] } '
# Do not edit this file - Generated by Perlito5 9.0
use v5;

• educated_foo commented on The Perl Learning Environment

  There are a bunch of Perl REPLs, from perl -de0 to things requiring lots of Moose silliness. Have you tried using one of them?

• mascip commented on Perl5 in the browser update

  Very naive question Flavio:
  if i make a website with Perl5 (say, with the Dancer framework), do you think that some day i will just be able to compile it into Javascript with Perlito, and run it in a mobile phone? Or is it more complicated than that?
