So after my last blog post, I started a gist to keep track of "how would I write PCT". I called it PACT, the Parrot Alternate Compiler Toolkit. I suppose I could have called it PCT2, but I really don't want to try to claim it will 100% replace PCT. PCT's very valuable to the people using it right now, but there's no small desire to add to it and I'd like to help it be better. Parrot's main audience, to my mind, is prospective compiler writers and the easier we can make their lives the better.

On behalf of the Parrot team, I'm proud to announce Parrot 3.8.0, also known as "Magrathea". Parrot (http://parrot.org/) is a virtual machine aimed at running all dynamic languages.
Parrot 3.8.0 is available on Parrot's FTP site (ftp://ftp.parrot.org/pub/parrot/releases/devel/3.8.0/), or by following the download instructions at http://parrot.org/download. For those who would like to develop on Parrot, or help develop Parrot itself, we recommend using Git to retrieve the source code to get the latest and best Parrot code.

The hard "pencils down" date was Monday, so now seems like a good time for a blog post summarizing what I ended up completing.
I have DPDA generation and parsing working for LR(0) and SLR(1) grammars. I have the beginnings of a grammar specification DSL (a grammar, but no actions or tokenizer yet; it's in the dsl branch). I do not have support for LALR(k) grammars or general LR(k) grammars. I have not implemented generating code to parse grammars (as opposed to interpreting the DPDA in order to parse them).

I've spent the last few days cleaning up my branch: adding documentation, checking that it passes the code standard tests, and trying compiling Rakudo nom. Don't get too excited, we can't compile nom directly to bytecode. Heck, it can't compile squaak directly yet. But I wanted to make sure that all my tinkering hasn't broken the original PIR generation path.

Actually, I suppose the flight has really just begun. It's true that GSoC is nearly at its end but, ironically enough, it doesn't really feel like the end but more of a new beginning. A new debug data format is in the works and it has so much potential!

While I didn't implement everything I thought I would, there is now a basic framework for bytecode generation in the nqp_pct branch. I'm uncertain if it should be merged... While the bytecode generation doesn't fully work, it doesn't interfere with the existing usage of PCT and does have the nice feature that PAST::Compiler is now written in NQP for ease of hacking. I'll leave that up to the rest of the community to decide. The rest of this blog post is the contents of
docs/pct/bytecode.pod, which I hope will be helpful if anyone want to explore what I've been working on all summer.

With only two days left before the hard dead line and that will the end of my first GSOC . These three months has given me a tremendous insight into the world of open source, scripting languages and off-course compilers.
The good parts

It's been a while since I've posted - real life has been crazy with moving and setting up and finals. That's my fault because I didn't take into account the fact that I would be moving nor my finals being right around the time GSoC would be ending. The good news is that I've moved and setup my place (hooray for having my own office) and my classes are done - I've written the last research paper and taken my last final for my masters.

After missing action from some time, Corella is rising again . Right now Corella is not able to compile itself which was intended to but I'm trying to cover as much as possible and will give my best in this week. Corella's object system ("Corella-System") is ready and working.
Worked on arrays today and now corella is having support for arrays and even multi dimentional arrays as given in the ecmaScript.
var arr = 
.sub 'main' :main

OTTO. Apes don't read philosophy.
WANDA. Yes they do, Otto. They just don't understand it.
Now let me correct you on a couple of things, OK?
Aristotle was not Belgian. The central message of
Buddhism is not 'Every Man For Himself'.
OTTO. You read...
WANDA. And... the London Underground is not a political
movement. Those are all mistakes, Otto. I looked them up.
Now. You have just assaulted the one man who can keep you
out of jail and make you rich. So, what are you going to do
about it, huh? What would an intellectual do?
What would Plato do?
-- A Fish Called Wanda, by John Cleese.
With that, I'd like to apologize for Parrot 3.7.0, also known
as "Wanda". Parrot is a virtual machine aimed
at running all dynamic languages.
Parrot 3.7.0 is available on Parrot's FTP site, or by following the
download instructions. For those who would like
to develop on Parrot, or help develop Parrot itself, we recommend getting
the latest and best Parrot code from github.
