digitalmars.D.learn - Generate crc lookup table Dlang style
- Volcz (18/18) Jan 26 2014 Hi,
Hi, While solving a unrelated programming problem I ended up copying a CRC16-CCITT implementation Google found for me. After I thought it would be nice to make a D style implementation with some compile time magic. My idea was to implement something similar to: http://www.ross.net/crc/download/crc_v3.txt http://www.zorc.breitbandkatze.de/crctester.c generating the CRC lookup table compile time. Now. For me it seems like this it should be possible to be accomplished with the following function definition: T generate_crc_table(T)(T polynomial, T initialValue, bool refin) Here is a Gist with my attempt: https://gist.github.com/NVolcz/8635416 Where does crchighbit come from, I'm missing something? Could there possibly be a D programmer somewhere out there with the expertise to help me?
