Focus On: Deleaker - a Delphi, C++ & C# Memory Leak Detector

Image
A week or so ago Artem Razin got in touch with me to ask if I'd take a look at his  Deleaker  program and mention it in my blog. I agreed and this blog is about how I've been using it and what I've discovered. This is by no means a definitive account of how to use the program and I'm far from an expert user. For the final word on this program, see the Deleaker docs . You can get a free trial and pricing info from the Deleaker Website . Deleaker stand-alone window Disclosure This is the first blog I've written about a commercial third party program. For the sake of transparency I want to disclose that  I received a free license for this product from Artem, for which I'm grateful. Offer to other developers I'm happy to offer to blog about other useful development software (or Delphi libraries) from other small developers. For more info see my " Promoting Delphi developers & applications? " blog post. So what is it? Deleaker is memory leak detecto...

Initialising dynamic arrays

When writing some unit tests a while ago I found myself needing to initialise some dynamic arrays with test data. It would be nice if we could do something like this: var A : array of Integer ; begin A := ( 1 , 2 , 3 , 4 ) ; // !! WRONG end ; but we can't. So I decided to write some functions to initialise dynamic arrays to the contents of another array, be it a constant, a literal or another dynamic array. The result was a set of overloaded routines, one for each data type I needed to handle, for example for Integer and string arrays I had: function CloneArray ( const A : array of Integer ) : TIntegerDynArray ; overload ; var Idx : Integer ; begin SetLength ( Result , Length ( A ) ) ; for Idx := Low ( A ) to High ( A ) do Result [ Idx - Low ( A ) ] := A [ Idx ] ; end ; function CloneArray ( const A : array of string ) : TStringDynArray ; overload ; var Idx : Integer ; begin SetLength ( Result , Len...

CodeSnip 4.27.0 released with Delphi 13 support

Image
And finally ... after a few updates to reflect the release of Delphi 13 Florence , last but not least we have an update to CodeSnip . This program can test compile snippets with any Delphi compiler installed on the host computer, along with Free Pascal. But every time there's a new Delphi release CodeSnip has to be modified to be able to use it. I wish there was a config file to update, but it's not that simple with this ancient code base! So, CodeSnip 4.27.0 knows about the existence of Delphi 13, can use it for test compilation, can record the results of such compilations in its databases and can emit code that selectively turns warnings on and off for the compiler. That's the only new feature of this release. The docs and help file have been suitably updated. ➣  Download the v4.27.0 release from GitHub . BTW the first time you run this new version after installing Delphi 13, CodeSnip will notice and will offer to configure itself to use the new compiler, unless you'v...
