DelphiTools, SamplingProfiler and General Delphi News
Just a quick post to announce the Delphi-WebGPU repository.
What ?
Why ?
To take the words from webgpu-headers:
While WebGPU is a JavaScript API made for the Web, it is a good tradeoff of ergonomic, efficient and portable graphics API. (more…)
With Delphi 12.Community Edition released not too long ago, it was an opportunity to test run what’s possible with FMX on the 3D side.
And while Delphi FireMonkey has 3D support, it’s not really a core feature. For a test run, the simplest of all 3D entities, a point cloud can serve as a decent stress test.
Point Clouds are now ubiquitous with the advent of 3D capture devices, which go from LIDAR to RGB-D cameras and all kinds of AI augmented approaches. So there is a plethora of 3D point cloud datasets out there.
Recent commits to the DWScript repository doubled the compiler performance when compiling many small scripts, like happens in the unit tests suites.
This started from a first profiling run where the memory allocations around the UnicodeLowerCase function came out as top bottlenecks.
Thing is, Pascal being a case-insensitive language, there are lots of case-insensitive comparisons, lookups, searches and hashes, and turns out a key hash code was computed with code like
A tentative new language feature has been pushed to the DWScript repository: “property reintroduce”.
The aim is to allow a method to be reintroduced as a property, and do so in a non-fatal fashion so it can be pushed to production and existing code can be migrated iteratively. (more…)
For quite sometime the issue tracker at BitBucket has been barely usable, and Atlassian does not seem to have bothered fixing it… So if you have issues with DWScript, please now post them on the issues tracker of the GitHub DWScript mirror. (more…)
In the wake of Delphi 12 support, DWScript just got support for the “triple apostrophe” multi-line string syntax introduced with Delphi 12. This syntax comes in addition to the previously supported multi-line syntaxes.
As there is some degree of ambiguity in the new syntax, the syntax in DWScript is based on my current understanding of what the Delphi 12 doc and parser do. (more…)
DWScript has been updated for Delphi 12 support, there are only minor changes required and they are in the DWScript repository.
On a side note, the Delphi 12 IDE definitely feels more snappy when navigating code or invoking code insight (ctrl+space) on large projects (more than 2 MLOC), which is nice!
Support for “readonly” class fields has been added to DWScript repository.
The syntax is similar to the one in Oxygene, with a qualifier following a field declaration: (more…)
SamplingProfiler 23.8.21 is now available. This version is all about cosmetic fixes:
Also the zip only includes the 64bit version now (which should work with 32bit executables).
A new SamplingProfiler v23.4.25 version is now available.
The main highlight of this release is support for HDPI displays, no more blurry text on that 4k monitor!
This is also the first version compiled with Delphi 11.3, which fixed several HDPI issues in the VCL that were holding back HDPI support.
