Avoid duplicate code in C++, define a class Color with operation bit shifting.

Objective

The objective of this library is to avoid code duplication with C++.

Problem Definition

Throughout my projects, it's common to have to write a class that defines a color, in components like red, green, blue and alpha. Obviously it means writing the same properties and methods for a class, leading to code repetition. Action to be avoided at all costs.

Downloads

This library is not designed for impressive performance (although this is also an aspect that I take into account when implementing the library), is designed to avoid duplicate code.

How to Use

With the arrival of CMake 14, a script was added that allows to get repositories from the Internet, taking into account this the user TheLartians decided to write a script for CMake that acts as a package manager. In my opinion, this marks a new step for C++ and CMake, allowing work with libraries that are downloaded and updated without direct intervention of the user.

How to use

To use this library, you need the script written by TheLartians, named CPM.cmake (acronym for CMake Package Manager). Add it to your project, for example, under the CMakeModules and then in your CMakeFiles.txt write the following:

Include(CMakeModules/CPM.cmake)

CPMAddPackage(
  NAME Cup.Graphics
  VERSION 2020.0505
  GITHUB_REPOSITORY Andres6936/Cup.Graphics
)
 
TARGET_LINK_LIBRARIES(<TARGET> PRIVATE Cup.Graphics)

• The directory CMakeModules should be created in case it does not exist.
• <TARGET> must be replaced by the executable to which you will link.

My proposal for using the library within your code is to use encapsulation.

using namespace Cup::Graphics;

Color color(233, 245, 132);

	assert(color.getRed() == 233);
	assert(color.getGreen() == 245);
	assert(color.getBlue() == 132);
	assert(color.getAlpha() == 255);

	color.setRed(56);
	color.setGreen(87);
	color.setBlue(156);
	color.setAlpha(69);

	assert(color.getRed() == 56);
	assert(color.getGreen() == 87);
	assert(color.getBlue() == 156);
	assert(color.getAlpha() == 69);
