DelphiTools, SamplingProfiler and General Delphi News
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.
“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 (?:).
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:
Latest DWScript SVN introduces support a new “for var” syntax extension for loops.
It combines the loop with the loop variable declaration (type-inferred), while scoping the variable to the loop.
The syntax of “for to/downto” loops is thus extended to:
A new DWScript 2.3 preview 2 7zip (422 kB) is available for download for those that don’t use the DWScript SVN. This version should be the last before a release candidate for 2.3. As the lead version is Delphi XE, users of Delphi 2009, 2010, XE2 and XE3 are especially encouraged to report any issues they encounter. FreePascal support is still considered experimental at this moment.
