This is the full self-contained source code for y-cruncher v0.6.3's Digit Viewer.
It includes everything including the heavily optimized back-end conversion code.
To Compile (Windows):
- Double-click
Windows - Compile All.cmd. - You need to have Visual Studio 2012 installed in the default directory.
To Compile (Linux):
- Run
Linux - Compile All.shfrom the directory it is in. - x64 and a sufficiently new version of GCC is required.
A Visual Studio 2012 project has been provided.
The compiled Windows binaries have also been included.
Running Digit Viewer.exe will automatically do CPU-dispatching to select one of the 4 binaries to run.
If you intend to use and modify the code, the classes of interest are in:
/source/y-cruncher/DigitViewer
You can see how they are used in
source/DigitViewerOptions.h
To date, I've been too lazy to write a document on the compression format and how the .ycd files are laid out. But it should be pretty easy to see from just examining it through a hex viewer.
Two things that might be useful:
- Base 16 .ycd files are stored as 64-bit integers words with 16 digits per word.
- Base 10 .ycd files are stored as 64-bit integers words with 19 digits per word.
In both cases, each 8-byte word is little-endian.
Directories:
- y-cruncher/CVN/ - This directory contains all the heavily optimized conversion code. You probably don't want to look at this. :)
- y-cruncher/ConsoleIO/ - This is where the console colors come from.
- y-cruncher/DigitViewer/ - This has all the Digit Viewer classes.
- y-cruncher/FileIO/ - What the names says. These are the file handles that the program uses.
- y-cruncher/Strings/ - Leftover from when y-cruncher was entirely a C program.
