DWScript 2.2 preview 3

A source archive file for DWS 2.2 preview 3 (231 kB)  is now available. This is essentially just a zip file (7zip actually) for those not using the SVN.

Changes since the last post are rather limited:

  • built-in “QuotedStr” function now accepts a second quoteChar parameter.
  • improved compiler robustness (keeps parsing and reporting more errors in more cases), clarified some compile errors.
  • improved unit tests coverage (84.6%).

Further changes since the last archive (preview 2) are listed in the following posts:

 

Delphi 64 beta official after all

Did the attention that my little April 1st post drew help set things in motion a little earlier than planned?

It’ll be denied, it wasn’t seen, and it can’t be proven, it’s just that the slides and the video look a bit rushed, but anyway, on a just released Delphi 64 sneak preview page on the Embarcadero website, there  is a now a “join the beta” link, were you can apply for the beta. However the beta isn’t open, and Delphi XE users will apparently have priority.

As for the preview keypoints themselves, Marco Cantu has an executive summary.

It seems the beta will be under the usual NDA terms, so it may be some more time before more details filter out.

Delphi 64 open beta now available!

In a bold (or unintentional?) move, a Delphi 64 beta has been released on the Embarcadero servers, there is no official announce yet, so hit the link below while it’s still there, it may not last long!

Delphi 64 (maybe open?) beta download

..alas this was just for april’s fool… Let’s hope the next announcement about Delphi 64 availability will happen before April 2012!

edit 04/04: coincidence? They’ll deny it, no one saw them do it, and anyway no one can’t prove anything, but the following announces have just been made:
Delphi 64-bit Compiler Sneak Preview and Beta – Official Announcement
Delphi 64-bit Compiler Preview and Beta Program
And Marco Cantu has the exec summary: Delphi 64 bit Sneak Preview
With none other than David “let’s-have-a-drink” Intersimone as host for Embarcadero page for “Pulsar” beta being http://www.embarcadero.com/products/delphi/64-bit

Kudos to the Firefox 4 TraceMonkey team!

I’ve been quite impressed with the JavaScript floating point performance in FireFox 4, which puts the Delphi compiler to shame. See for yourself this fractal rendering demo:

Mandelbrot Set in HTML 5 Canvas

I’ve made a version of the same code in Delphi XE (source + pre-compiled executable, 331 kB ZIP), and on my machine here, for the 480×480 resolution, where FireFox 4 gets the default view rendered in 124 ms, where the “regular” Delphi version, which is limited to the old FPU, takes about 200 ms…
