DelphiTools, SamplingProfiler and General Delphi News
Update: should now be available, BitBucket staff was very responsive, and Sophos AV as well. Two false positives remain by VBA32 and Cylance, which do not appear to have proper mechanisms to report false positive (not very professional for an AV vendor IMHO).
Support for BigInteger type in SmartPascal is being added in the DWScript repository, it is mapped to the new BigInt JavaScript type which is now supported by the major browsers.
This is going to be a work in progress over a few weeks. In part because the JS implementation is rather bare-bones with few support functions, and in part because with the BigInt type, the JS designers did away with some automated and implicit casting (uh?).
While refactoring a bit the way some “special” functions were handled in DWScript, I came about a case where the compiler started accepting strings as Math functions parameters.
While this comes naturally as an “interesting” side-effects of automatic typecasts, it left a feeling of “wrongness”, accepting literal code like Abs(“foo”) and then failing at run-time is asking for trouble.
As you have probably been made aware by the flurry of privacy policy updates in your mailbox, GPDR is coming.
While I am not convinced GDPR will not turn into a perfect showcase for “the road to hell is paved with good intentions”, this is also a good opportunity to update BeginEnd.net to use the 64bit version of DWScript and add a few missing features.

Just a quick notice that the DWScript source code has begun a transition to Delphi 10.2.3 up from Delphi XE.
The goal is to target Win32 and Win64 compilers, mobile platforms and Delphi Linux are currently not in the scope.

A belated Happy New Year and Best Wishes for 2017!
This site and news have been neglected for much of 2016, this year’s resolution will be to try and revive it a bit.
In particular announcements and articles have fallen way behind the code as far as DWScript is concerned. So I will start the year by attempting to rectify that.
DWScript now has support for the BigInteger type, which supports numbers with as many decimals as the memory allows.
This support comes in two flavors, either through a MPIR dll (a GMP fork) or through Rudy Velthui’s BigIntegers unit.
It occurred to me that SHA-3 being a cryptographic hash, it is one of those peculiar bits of code that are fully self-testing. Any bug in a cryptographic hash will quickly cascade to a different result, no matter the bug or the input.
This means the ad-hoc-compiler-monkey can be unleashed “safely”, and can be allowed to try “improper changes.”

A new kernel for SHA-3 (Keccak) cryptographic hashing has been committed to the DWScript repository.
It is almost 3 times faster than the Pascal version, makes use of MMX asm, and involved an “ad hoc compiler”.
