Components of Parrot

Hello, Some time ago, I announced I would be writing a paper on the architecture of Parrot. The paper will be about 10 pages (I think, at this point), so there will be quite a high level of abstraction in order to be able to fit all important info. (so no "class" diagrams, if one could even s

Global storage access

hi, if I understood correctly, the global storage is implemented as a hash table. If so, will it be possible to load this global hash table in a P register? So, for example, are there any plans to support this: $P0 = get_globals # put a reference to the global storage into register $P0

Syntax for Constructing new Objects (and classes?)

Hello, I have a short and simple question w.r.t. syntax for constructing new objects for the architect :-) Currently, it's done through: new P0, .Integer or in PIR: $P0 = new Integer # or .Integer I thought to have read somewhere this will be changed into something like this: $P0 = Inte

Testing PIRC

hi, Currently, compilers/pircdoes not have a test suite. I'd like to change that, but am not sure how to handle this. My idea was to have the PIR scripts parsed by pirc, which outputs *exactly* the same source (on success), which then should be compiled by IMCC. I'm not sure how to achieve t

compilers/pirc continued...

Hi, As suggested by particle++, I added a vtable to the parser in compilers/pirc. Now, it's very easy to output PIR /or/ PAST :-) from the parser, without too much extra code in the parser. However, as I've only just begun, only very simple stuff will be output. Changing the flag when creatin

Re: New generational GC Scheme

"tuned dynamically", as in at run-time? alexandre mentioned this may be possible on #parrot, but there may be trouble with decreasing the generation count. i don't know if run-time tuning of the generation count is necessary, but if so, i imagine that decreasing the count at run-time could be ac

PMCs and Objects question

hi, My question concerns functionality of PMCs and Objects. while reading the docs about the functionality of classes and objects, I read that the vtable entries of a class can be overridden to give the class special behaviour. I'd like to know if I'm correct (I just realized this), if I say
