blt::logging.v2

Found in the header file include/std/logging.h, blt::logging is a fast and simple single header logging library which can be used independently of BLT. Just include the header file anywhere in your project and in ONE cpp file define #define BLT_LOGGING_IMPLEMENTATION. If you are using BLT as a CMake library (as you should!) this is done for you.

• Compile Time Config

  • Using CMake
    • Several options are provided which disable various logging contexts, as such global logging can be disabled by passing -DBLT_DISABLE_LOGGING:BOOL=ON
    • Options follow the pattern of BLT_DISABLE_LEVEL where level is one of TRACE,DEBUG,INFO,WARN,ERROR, or FATAL.
      • This allows for individual logging levels to be disabled while leaving the others functional. These options can be combined.
      • See CMakeLists.txt for a complete list of options.
  • Standalone
    • The CMake options define global variables in a config file. If you are using logging standalone you will need to remove the config include.
    • Macros can be used in the same pattern of BLT_DISABLE_LEVEL to disable the various logging levels

Features / Examples

• Data Structures

  • Queue / Stack
    • faster than std::queue / std::stack
    • backed by a contiguous array

• Utility

  • Simple Random Wrapper Interface
  • Simple random functions based on the PCG Hash

  • String Functions

    • starts_with
    • ends_with
    • contains
    • toLowerCase
    • toUpperCase
    • split
    • trim
  • Logging
    • See blt::logging section above
  • Time
    • Current time in nanoseconds (without all the c++ gobbledygook)
      • Java's currentTimeMilliseconds
      • nanoTime as well
      • std::chrono::duration_cast<std::chrono::nanoseconds>(std::chrono::high_resolution_clock::now().time_since_epoch()).count() becomes blt::system::nanoTime()
    • Formatted time string with year/month/date + current time

• Profiling

  • Basic profiler with history and formatted output
