CTCrcLog

This repository is an experimental repository for a Compile-Time CRC Log Library. The library is an header-only library that enable the following:

1. Wrap every log message with the Message<>() template class provided by the library. E.g. std::cout << Message<FixedString("Error occured")>().get_message() << std::endl;
2. When compiling in debug (with -DDEBUG flag) the executable will print the string as is.
3. When compiling in release the executable will print the crc32() hash of the string. The strings won't be in the executable.
4. When compiling, another executable is created - crc_to_string - this executable contains a map between the crc32() values and the strings.

Prerequists

The library is using c++20 features, hence it requires a compiler that support it.

How to compile and run the example

mkdir build
cd build
cmake ../
# In case you need specific compiler use:
# CXX=/usr/bin/g++-9 cmake ../
make

Then, in the examples directory you will see two executables:

1. example - An example executable.
2. crc_to_string - An executable that contains a mapping between the crc32() values of the messages and the messages string.

$ cd examples
./crc_to_string 
2801838154 : System is up
3001801933 : Error occured

$ ./example 
2801838154
3001801933

$ grep -ai "System" ./example
