yafl

yet another fast log

Objective

The project demonstartes a mechanism to create an exteremly fast and low foot print logging.

Features

• simple log writing
• build system that takes care for everything
• binary logs
• reader

Flow

• write your log
  • LOG( "hello world #", number );
• cmake
  • m4 preprocess generate
  • log messages with numbers
  • map files: numbers <--> text
  • make
    • your project
    • yafl-reader / yafl-tail / yafl-grep / yafl-etc
• run
  • generates binary logs
• post processing
  • translate the logs to text
    • use standard text tools.
  • yafl-grep (yet to implement)
  • yafl-tail (yet to implement)
  • yafl-etc (etc.)

BUILD

download the repo it is a CMake project, create a build directory, cd into it and cmake and make this project. When everything is compiled run from the build directory ./logger/demo/logger_demo it runs current code in logger/demo/main.cpp whatever it is.

Look Around

If you havn't already, take a look at the PDFs in the main directory. They give a brief introduction to what os going on here. Then you can take a look at any: .cpp .h .sh and .map files in the binary directory. And take a look at the m4 directory to see how numbers are created from strings.
