D Programming Language Area
Introduction
This section aims to be a permanent home for the programs and guides I have made using D. Some of the
content has been on this site before but spread across various sections. Admittedly D is not the primary
language in use here, but it is a great language and hopefully this new section will help increase
awareness of it.
What is the D Programming Language?
From the D website:
|
D is a general-purpose programming language with static typing, systems-level access,
and C-like syntax. With the D Programming Language, write fast, read fast, and run fast.
|
The language aims to be fast and reduce errors, both very important features! Reading
the aims of the language, there are a lot of things to like about it.
Applications / Programs
The following are D versions of some of the command line programs that are on this site. Source is included with each of them.
To keep the download size small, these are provided as a 7zip archives.

Guides
Avi2Cvc - Converting from C to D
Summary of porting my Cybiko video conversion utility from C to D. The main reasons for this were
to improve its memory safety (I had already found one memory issue) and to take advantage of the other benefits that using D provides.

Avi2Cvc / Bmp2Cvi - Using Modules
How modules were used to reduce code duplication in these two programs making bug fixing and improvements easier.

Converting Iff2Bmp to D
Summary of porting my Amiga IFF to Windows Bitmap converter. Shows more advantages of using the D language.

Memory Safety - How D Prevents Out Of Bound Errors
In C, an out of bounds error / exception occurs if you try to read or write to an area of memory that is outside the amount allocated. This guide
shows how D can help prevent this type of error.
Read more!
Memory Safety - How D Can Prevent Use After Free Errors
A 'Use After Free' error is where after giving back (freeing) some memory, you carry on using it, in language like C these can
cause security and stability problems. This guide shows how using D can avoid this.

Squish - Performance Optimisation in D
Porting my Squish compression program from C to D initially resulted in terrible performance, this guide shows how I managed
to make it nearly 30 times faster!
