• Commented on PerlOnJava Gets a CPAN Client
  @The Mighty Buzzard: Fair point - decades of Perl error messages have trained us all to expect the worst. Since PerlOnJava has to deal with a unique situation (XS/C modules that simply can't compile on the JVM), I figured the...
• Commented on PerlOnJava Gets a CPAN Client
  Note: warnings are now fixed - **Spurious warnings** -- There's currently a bug where test description strings trigger `Argument "..." isn't numeric` warnings. Annoying, being fixed....
• Posted PerlOnJava Gets a CPAN Client to Flávio S. Glock

  If you’ve ever tried to run Perl code in a Java environment, you know the drill. Rewrite everything in Java (expensive, risky), or maintain two separate runtimes with all the deployment headaches.

  PerlOnJava offers a third path: compile your Perl to JVM bytecode and run it anywhere J…

• Posted Perl5 as a first-class script engine in Java - part 2 to Flávio S. Glock

  Perlito5 is an implementation of the Perl5 language that runs in the Java / JVM platform.

  jrunscript now works with the "Perl5" language parameter:

• Posted Perl5 as a first-class script engine in Java to Flávio S. Glock

  Perlito5 is an implementation of the Perl5 language that runs in the Java / JVM platform.

  Perl scripts can now be run from inside Java applications using the standard javax.script API:

  // $ javac -cp .:perl…

• Posted Perl5 to Java compiler - symbol tables, typeglobs, and call stack to Flávio S. Glock

  Perlito5 is an implementation of the Perl5 language that runs in the Java / JVM platform.

• 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”:

  $ a2p x.…

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

  This is the first release of the Perl5 to Java compiler.

  https://github.com/fglock/Perlito/releases

  In the github page there is a link to the "jar" file and the lib directories for JVM-specific Perl modules.

  The "perl…

• 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.

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

  Yati, Bas, Luca and I hacked on the Perlito Perl5-to-Java compiler and also a bit of …

• 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:
  package ScriptEngineManager {
      import => "javax.script.ScriptEngineManager"
  };

• Posted Perlito - reviewing some older code to Flávio S. Glock

  Today I've finally updated the Perlito compiler ChangeLog, this covers a little more than a year of commits.

  The most significant update was the new Perlito5-to-Java backend, which is work-in-progress. It covers a lot of…

  The compiler now has a small test suite. The main additions in the last 10 days were implementing global…

• 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

  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…

  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…

• 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?
