Welcome to the new DelphiDabbler blog

Welcome to this new blog, which I'm thinking of as an extension to DelphiDabbler.com where more peripheral programming stuff can be discussed.

I'll also use it for news of happenings on the main site.

Will I keep up with it? Let's see how it goes!

    As an occasional reader of your site, adding a blog outlet for it is a good idea I think. Mind you, why not take the further step of adding a link to DelphiFeeds.com and getting your RSS feed included there? It would make your site more widely known amongst the online Delphi community, which would definitely be a good thing.

    Thanks for suggesting this Chris - I didn't know about it. There's now a link to DelphiFeeds.com on this page.

Comments are very welcome, but please don't comment here if:

1) You have a query about, or a bug report for, one of my programs or libraries. Most of my posts contain a link to the relevant repository where there will be an issue tracker you can use.

2) You have a query about any 3rd party programs I feature, please address them to the developer(s) - there will be a link in the post.

3) You're one of the tiny, tiny minority who are aggressive or abusive - in the bin you go and reported you will be!

Thanks

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...

Deleting elements from a dynamic array

In my blog " Initialising Dynamic Arrays " I mentioned I have been writing some unit tests that needed numerous repetative array initialisation operations. Well, one of the other common operations I found myself writing was the deletion of items from dynamic arrays. So I decided to find a generic way of doing this. Assuming we know the index of the item to be deleted we need the equivalent of Delphi's built-in Delete procedure for strings. If you read the previous post you won't be surprised to learn that I decided to further extend the Generics.Collections.TArray class by adding to the TArrayEx class I introduced there. My first attempt emulates Delphi's Delete procedure by deleting the array element in-place: i.e. it updates the array passed as a parameter. Unsurprisingly the method is called DeleteInPlace . Here's how it goes: type TArrayEx = class ( TArray ) public .. . class procedure DeleteInPlace < T > ( var A : ...
