C++ Utilities

A collection of small utilities I like having around

• allocator

  • Memory allocator on the cheap
  • Stack behavior for pre-allocated memory
  • CUDA version available

• command_line

  • C++17
  • For processing command line arguments
  • Demonstrated in example_main.cpp

• config_reader

  • C++ 17
  • Read configuration file of key value pairs
  • key=value or key = value
  • Comment lines with '#'
  • Overload for specifying required keys

• cuda

  • Helpers and macros for CUDA programming
  • Templated stack for managing device memory

• directory_helper

  • C++17
  • Provides file paths of a given extension in a directory

• execute

  • C++17
  • Easy parallel execution

• for_each_in_range

  • C++17
  • Iterate over 1D and 2D integer ranges
  • Sequential or parallel

• imgui_start

  • Starting code for an application using Dear Imgui
  • Windows (DX12)
  • SDL2
  • Sample app that accepts user input and modifies state in the background

• leak_check

  • Check for memory leaks using Visual Studio

• libimage

  • Basic image processing library using Boost GIL or stb_image
  • Now deprecated by https://github.com/adam-lafontaine/SimpleImage
  • Boost GIL
    • C++17
    • Add _CRT_SECURE_NO_WARNINGS to Preprocessor Definitions in Visual Studio
    • Sequential and parallel for_each and transform algorithms
    • Has problems with color bmp images
  • stb_image
    • C++17
    • Similar interface to boost::gil::image_t and image_view_t
    • Create an image object and load image data into it
    • Image exposes begin and end pointers to raw memory
    • Create a view from the image
    • A view is a subsection of the original image and points to the image's memory
    • Process the view if operations are non-trivial

• libuvc

  • Single header file created from the Libuvc library (https://github.com/libuvc/libuvc)
  • #include "libuvc.h" for access to api
    • #define LIBUVC_IMPLEMENTATION in exactly one file before including the header
  • Need to install libusb and libjpeg
    • sudo apt install -y libusb-1.0-0-dev libjpeg-dev

• make_start

  • Makefile starting point

• memory_buffer

  • Encapsulated memory allocation and pointer arithemtic

• normalize

  • C++17
  • For custom scaling of values from one range to another
  • convert_config.hpp
    • Set minimum and maximum values type of scaling e.g. linear or sigmoidal
    • Add any scaling schemes
  • normalize.hpp
    • Uses values set in convert_config.hpp to normalize a given value
  • charmap.hpp
    • Used with normalize.hpp to convert a given value to a character
    • Multiple values can be saved as strings
    • TODO: bytemap.hpp
  • convert.hpp/cpp
    • Used with charmap.hpp to convert multiple values into a string

• profiler

  • Simple profiler for function calls

• qsprintf

  • Wrapper for stb_sprintf.h
  • Defined macro for renaming to qsprintf etc.

• ring_buffer

  • Templated ring/circular buffer

• stopwatch

  • C++17
  • Wraps std::chrono to easily time code execution
