Description :
This is my implementation of a JSON parser, developed from scratch, based on my Generic Tokenizer library.
It can parse JSON files and provide the contents via a tree-based data model.
Also read the correspondig article which explains the implementation in detail:
Tutorial: A practical approach to write a simple JSON parser yourself
The package contains beside the whole source code a test application with example JSON files (based on my Simple Test Environment) and a demo application which parses a provided JSON file and prints the content of the data model to console.

Description :
This is a demonstration of panning (moving a small view port in a larger world) and zooming (scaling the view port window).
The demo constructs a global 2D world (having lines, rectangles and circles) that is far larger than the window for display, so only a cutout (called "view port") of the global space is visible.
The view port can be move around the world (called panning) via mouse by pressing the left mouse button and move the cursor in the view port window while the mouse button is being pressed. The size of the view port can be increated and decreased (called scaling or zooming).

Description :
This is my own simplistic solution how to implement a basic unit test environment in C#.
It provides a default behavior for console mode applications, but is configurable by providing your own interface implementations.

Of course, I could have used NUnit or any other of the million (much more sophisticated, better, faster, more usable, more comprehensive, ...) frameworks, but I did not want any dependency to a foreign framework.
So here you have the result of my minimalistic approach.

History / Updates:

Description :
This little application is my playground to start fiddling with camera-to-perspective and perspective-to-screen transformation.
It has no real use - it's just my own try to project a single 3D point and wireframe cube from camera space to screen and investigate the transformation steps.
I guess it makes most sense to read my article Simplistic fixed camera to perspective screen transformation on my website along with playing around with this tool to gain the biggest benefit for understanding the process.>

A simple raycasting demo in C#.
Raycasting is rendering technique to create a 3D view of a 2D map and can be seen as the most basic form of raytracing.
Having started coding it somewhen in 2014/2015, I pretty soon lost interest and was also never satisfied with the result. Now, after lying around on my hard drive for around five years in which I was never again motivated to continue development, I release it "as it is".

Version : 1.02

Source available : YES

Description :
This tool creates an include dependency tree of C source files (*.c, *.h, *.cpp) and checks if there is a cycle in the hierarchy. The user has to specify all relevant source/include folders as well as a root file (normally the file which has the main() routine) which is used as root node for the include tree.

If the tool is executed without any arguments, it's a wizard-like GUI application. When providing commandline arguments, it runs as console application. Note that this is a simple tool and does not evaluate preprocessor statements and thus no conditional includes.

Package includes application, source code and some little tests to show the usage of the tool.

Description :
I 'hacked' this tiny app very quickly for personal needs. I wanted my music files sorted after file creation / modification date and none of the media players I use provided this functionality. This tool just parses a directory (with/without subdirectories) for music files and writes them to a *.m3u file (ready to be loaded with e.g. Winamp) sorted after modification date (from oldest to newest). That's it - maybe you are searching for exactly this tool. If not, as the source is easy, feel free to take it as a starting point to generate your own playlists by implementing your own sorting criterias.
