# C++ Programming Guidelines
## Basic Principles
- Use English for all code and documentation.
- Always declare the type of each variable and function (parameters and return value).
- Create necessary types and classes.
- Use Doxygen style comments to document public classes and methods.
- Don't leave blank lines within a function.
- Follow the one-definition rule (ODR).
## Nomenclature
- Use PascalCase for classes and structures.
- Use camelCase for variables, functions, and methods.
- Use ALL_CAPS for constants and macros.
- Use snake_case for file and directory names.
- Use UPPERCASE for environment variables.
- Avoid magic numbers and define constants.
- Start each function with a verb.
- Use verbs for boolean variables. Example: isLoading, hasError, canDelete, etc.
- Use complete words instead of abbreviations and ensure correct spelling.
- Except for standard abbreviations like API, URL, etc.
- Except for well-known abbreviations:
- i, j, k for loops
- err for errors
- ctx for contexts
- req, res for request/response parameters
## Functions
- Write short functions with a single purpose. Less than 20 instructions.
- Name functions with a verb and something else.
- If it returns a boolean, use isX or hasX, canX, etc.
- If it doesn't return anything (void), use executeX or saveX, etc.
- Avoid nesting blocks by:
- Early checks and returns.
- Extraction to utility functions.
- Use standard library algorithms (std::for_each, std::transform, std::find, etc.) to avoid function nesting.
- Use lambda functions for simple operations.
- Use named functions for non-simple operations.
- Use default parameter values instead of checking for null or nullptr.
- Reduce function parameters using structs or classes
- Use an object to pass multiple parameters.
- Use an object to return multiple results.
- Declare necessary types for input arguments and output.
- Use a single level of abstraction.
## Data
- Don't abuse primitive types and encapsulate data in composite types.
- Avoid data validations in functions and use classes with internal validation.
- Prefer immutability for data.
- Use const for data that doesn't change.
- Use constexpr for compile-time constants.
- Use std::optional for possibly null values.
## Classes
- Follow SOLID principles.
- Prefer composition over inheritance.
- Declare interfaces as abstract classes or concepts.
- Write small classes with a single purpose.
- Less than 200 instructions.
- Less than 10 public methods.
- Less than 10 properties.
- Use the Rule of Five (or Rule of Zero) for resource management.
- Make member variables private and provide getters/setters where necessary.
- Use const-correctness for member functions.
