海外TECH	DEV Community	namespace ra :: How to Write C++ Library	https://dev.to/ra101/namespace-ra-how-to-write-c-library-4a4c	namespace ra How to Write C LibraryPrerequisite One must be familiar with coding in C I coded my first C libraries years back I had just started college and wanted to do something solid One fine evening I was looking back at that code It was so poorly written So I started fixing it I googled C Convention After many search results I found out there are no good resources out there So I took upon myself To Write One These are coding practices one may follow to write readable good code File Types Any programing file in the end is nothing but a text file with a fancy extension In the Book of Genesis the mentioned naming style is c for C cpp for C h for headers independent of C or C But due to the opensource nature of GNU A bunch of different assembler and compilers were made which came with their own extensions variations such as cc C cxx c and hh H hxx hpp h TBH Just chose one set of extensions after all even txt can be compiled I use Since Most IDE recognize them c for C cpp for C h for C headers hpp for C headers makefile A makefile is a special file containing shell commands that you create and name makefile no extensions It is executed using the make command My Typical makefile looks like this VariablesCXX g CXXFLAGS std c w lt command gt lt dependencies gt would have worked with main cpp as well added rest of dependencies to add a check before compiler returns an error build main cpp local header hpp includes external lib hpp echo n nmain cpp Building CXX CXXFLAGS o main out main cpprun main out echo n nmain cpp Executing main outclean main out echo n nmain cpp Cleaning rm main out test command is for show I have probably never used it test test cpp echo n ntest cpp Building CXX CXXFLAGS o test out test cpp echo n ntest cpp Executing test out echo n ntest cpp Cleaning rm test outall build run clean To build run and clean the main cpp make allNOTE use MMD flag to get a d file containing all dependencies PreProcessors The preprocessors are the directives which instruct the compiler to preprocess the information before starting compilation All preprocessors start with For example include lt iosteam gt These are the coding practices I use Double Quotes for including local headers This rule increases readability of Code Levels of includes I picked this habit while working in python with linespace between them First for core g system files Second for externally added libraries Third for locally created files pragma one for header filesWhat include does is that it adds the mentioned file at the top of the code you can check it by using save temp flag during compiling So If a header file is called again somewhere else The Whole Code will be compiled again Since Header files don t typically initiate a variable It is Advised to compile it once for performance enhancement One can use indef include endif but it is tedious so pragma once reduces possibilities for bugs due to manual mishandling DO NOT USE using namespace in header fileIt may lead to a re declaration error It may populate the header file with its functionSO According to the above rules A good header would be pragma once line space afterwards include lt system file gt include lt system file gt line space afterwards include lt external lib gt line space afterwards include lt external lib gt club external libs together include lt external lib gt line space afterwards include local file line space afterwards using namespace DO NOT USE IN HEADERSnamespace ra Nomenclature File namespace Class function Nothing is fixed one may use camelCase PascalCase orsnake case I personally find snake case to be more readable Template Parameter same as above no rules I prefer PascalCase here Constants Macros UPPER SNAKE CASE is preferred everywhere Variables Before IDE s were a thing People just couldn t hover over variables to get info So some old libraries use the following conventions m lt any case gt for private members t lt any case gt for function parametersI personally discard this rule Taboo of Naming Check this link Comments C allows for types of comments This is single line Comment This is Multi Line Comment Generally speaking single line comments provide more control over the appearance and are considered better As a python developer I wholehearted disagree This is how I prefer my code class custom class A definition of what does this class represent Preferred Usage private How this variable affects Where this may be used float variable What does this function do void function void custom class function A definition of what does this function do Input Output Custom Exceptions Custom exceptions provide you the flexibility to add attributes and methods that are not part of a standard programming language These are most helpful in Debugging when code is unable to compile Below is My Favorite Exception Codenamespace ra class external exception public std logic error public external exception std string function builtin FUNCTION std logic error function called for external exception Usagevoid main throw ra external exception Outputterminate called after throwing an instance of ra not implemented exception what main not implementedLet me explain In argument of constructor of exception it says std string function builtin FUNCTION builtin FUNCTION return the source location when called Since called in Argument whenever it is initiated that is the source location Essentially Making it a traceable ExceptionHere We have inherited from logic error but other exceptions errors could be found hereNOTE In C Exceptions and Errors are the same but in theory Exceptions are something that could be handled whereas errors should not be as they break the system ModularityA Modular design is shown to improve the design process by allowing better re usability relatively low maintenance workload handling and easier debugging processes Modularity in C can be achieved by the following TemplateAs defined here A C template is a powerful feature added to C It allows you to define the generic classes and generic functions and thus provides support for generic programming Generic programming is a technique where generic types are used as parameters in algorithms so that they can work for a variety of data typesTemplates can be represented in two ways Function templatestemplate lt typename TemplateKlass gt TemplateKlass get maximum TemplateKlass x TemplateKlass y return x gt y x y Class templatestemplate lt typename TemplateKlass gt class custom class private TemplateKlass x y public custom class TemplateKlass TemplateKlass I am will not into details As there are far better resources Function as Argument We can pass a function in the argument of another function Well Actually A function pointer is passed to be exact This comes in handy in the situation where you have multiple services for the same request for example Hashing you can use so many third party algorithms for hashing bool verify hash std string hash func std string This will take in any function with input and output as a string return hashed output hash func input InheritanceI picked up this in my UnityD days In UnityD Almost everything is inherited and then used The plan is Simple Create a class with a bunch of public members all throwing error And Then Everyone would have to Inherit that class and override it For Exampleclass base class Everyone will inherit from this class public base class base class float throw not implemented exception operator std string throw not implemented exception class extended class public base class This is how Inheritance would work private float m temp public extended class extended class float t temp m temp t temp operator std string return std to string t temp If you think I have missed something or you have other coding style or some advice do let me know I might append to this post Make it one central point of all information	2022-02-22 21:24:08
