New Release 2.2.0 of File Date Comparison Utility

My little command line Windows program, compfiledate, has had a bit of an overhaul.

The program take two file names and compares either the creation date or modification dates of the files. Various comparison operators can be specified. Normally the program operates silently and returns 0 if the operator returns false and 1 if it returns true. Operators can be specified either in English or as mathematical operators. See the docs for a full list of operators and options.

I've finally stopped compiling it with Delphi XE and moved to Delphi 12.1. Taking advantage of the move to Delphi 12.1 there's now a 64 bit version of the program in addition to the previous 32 bit exe.

I've also fixed a bug that meant that "file not found" errors were returning a 0 to the OS instead of the desired error code (104).

Other than that the release build process has been moved from Make to MSBuild.

If you want a copy go to the GitHub release page.

Here's a look at some command line parameters and output at their most verbose:

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 : ...

New Array Utilities Library Unit released

Image
Yesterday I added a shiny new unit to the DelphiDabbler Code Library - the Array Utilities Unit . It lives in the ddablib/arrayutils  repo on GitHub. This unit, named DelphiDabbler.Lib.ArrayUtils.pas ,   provides a single "Advanced" record, TArrayUtils , that contains static methods that perform common operations on generic arrays. There are numerous overloaded versions of many of the methods. Every method operates on a given generic array that is passed as a parameter, either as an array of T or a TArray<T> . The unit requires Delphi XE or later. It has been tested with Delphi XE and Delphi 12. The code depends only on the Delphi RTL, so it should work for any platform supported by Delphi and be both VCL and FireMonkey compatible. I've only tested Windows 32 bit and 64 bit targets. There are far too many methods to describe in here, but you can find them all listed and explained in the comprehensive  online documentation . As a taster you'll find Methods that ...
