DWScript now has database support classes built-in, these are based on a thin, interface-based layer, and can be used Delphi-side as well to get automatic memory management for simple DB access.
It currently supports mORMot SynDB and Universal InterBase, meaning it gets high performance native connectivity to SQLite, FireBird, Oracle, ODBC and OleDB (MySQL, MS SQLServer, MS Jet, AS400…).
Version 1.8.0 of SamplingProfiler is now available.
The options dialog now support Delphi XE2 & Delphi XE3 search/browse paths, other changes are only indirect fixes/improvements related to the components and libraries used in SamplingProfiler.
This is a simple trick that can be handy to cleanup or simplify Boolean expressions, and is always good to have in your code-writing toolchest: De Morgan’s laws.
These two laws allow to apply a negation to an and or or expression:
“if” expressions are now supported in DWScript SVN, those were introduced to Pascal by Oxygene a couple years back, and are Pascal’s verbose version of the C ternary operator (?:).
After having survived the Mayan apocalypse and just before the year ends, and the US economy falls from the fiscal cliff into the pit of recession, here is a quick look at thirteen features of DWScript, so you don’t come into 2013 unaware 🙂
The Gabelou is now available in the DWScript SVN, this is a set of classes and rules that aims to watch over coding styles.
Currently only a handful of naming rules are declared, with more coming.
You can run the Gabelou by adding the dwsGabelou unit to your uses, then create an instance, add custom rules or use built-in ones (f.i. those in dwsGabelouStdRules), compile a script program as usual, then invoke Gabelou on the compiled program:
With the end of the world in a few days, it’s time to flush the what’s new log for DWScript.
There are two major items that will be discussed in future posts:
Also the old Indy-based webserver demo is being replaced by one based on Synopse high-performance http server classes.
Recently stumbled upon node-webkit, an open-source from Intel Open Source Technology Center, which is deliciously “simple”: combine a standalone webkit (Chromium) build and node.js into a runtime.
Webkit/Chromium brings a high-performance HTML5 environment with JavaScript JITting compiler, WebGL, Audio, hardware accelerated Canvas, camera access, etc.
DWScript now has a new “unit namespace” feature, which aims at killing several birds with one stone:
Now for a bit of hypothetical polling! thinking on the generics/templates syntax, one can’t quite shake the feeling Delphi got the C#/C++ generics/templates syntax. The < and > can’t be read out loud, and just look like an out of place reuse of the comparison symbols.
