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.

This is a summary
The soft deadline has passed and the hard deadline is not far away. Soon, what is likely to be my last GSoC will be over. And it was great! These three years I've had the summer job of my dreams. I worked on projects I was passionate about, using tools I liked and with people I liked.

Well, GSoC is starting to wind down. I can't believe it's almost over. It feels like the "pencils down" date just jumped up out of nowhere. I had a lot more planned for HBDB but there are many flaws in Parrot's design that make even some of the most basic debugging tasks very difficult which I'll explain in a moment.

I'm far behind on my project, unfortunately, and, upon dukeleto's urging, I've written up a new timeline that I think I will be able to finish before Summer of Code ends.
First, I'll summarize what I have done:
- An object representation for grammars
- An object representation for deterministic push-down automata(DPDAs)
- Generation of DPDAs for LR(0) grammars
- The beginnings of an interpreter for DPDAs
And what I haven't done:
- Actually producing a parse tree while parsing

*tap, tap, tap* Is this thing on? It is? Drat, I had hoped it wasn't and I'd have something to blame for the long silence.
Due to the issues I'm about to describe, my old schedule is a little off. The important schedule note is that the official "pencils down" date is August 15th, aka next week. Current plan is to power through as much as I can in the next few days. At this point, I doubt that my branch will be merged into master before the end of GSoC, but I do intend to keep working on it.
The core of my problem is in this line from my last blog post:

With the recent addition of the as_string method to UnManagedStruct and Ptr PMCs (see my last post) and the get_pointer vtable in ByteBuffer now is easier to pass and get strings from NCI (parrot Native Calll Interface).
To pass a string to a NCI 'p' parameter you just need to create a ByteBuffer and set the string to it, maybe after trans_encoding it, and add the zero-termination required in most usages by pushing a 0 value. ByteBuffer takes care of memory management.
