Norminette-inspired C++ Linter & Formatter

This repository provides configuration files and Makefile snippets to enforce style checks and automatic formatting for 42 C++ assignments.

It is designed to simulate a "C++ Norminette" by enforcing C++98 compliance, Orthodox Canonical Form, and strict naming conventions based on Google Style.

Style & Coding Rules

The configuration enforces the following rules using clang-format and clang-tidy:

1. General Formatting

Item	Value	Note
Standard	C++03	Treated as C++98 compatible
Indent Width	2 spaces	No tabs allowed
Column Limit	80 chars	Hard limit
Pointer Alignment	Left	int* n (Not int *n)
Include Sorting	True	Headers are sorted automatically

2. Linting & Complexity (C++98)

Item	Value	Note
Function Length	Max 45 lines	C++ allows slightly longer functions than C
Orthodox Canonical Form	Required	Classes must have default constructor, copy constructor, assignment operator, and destructor
C++11 Features	Forbidden	Pedantic C++98 check (No auto, nullptr, etc.)

3. Naming Conventions

Type	Case Style	Example
Classes	UpperCamelCase	class MyClass
Functions	UpperCamelCase	void MyFunction()
Variables	snake_case	int my_variable;
Private Members	snake_case + _	int private_member_;
Struct Members	snake_case	int struct_member;
Global Constants	k + CamelCase	const int kGlobalConstant = 42;

Setup & Usage

1. Install Dependencies

Install the required tools (clang-format and clang-tidy).

make install

2. Configure Your Project

Copy the .clang-format and .clang-tidy files provided in this repository to the root directory of your project.

3. Update Your Makefile

Add the following rules to your project's Makefile to enable the linting commands:

cppformat:
	clang-format -i *.cpp

hppformat:
	clang-format -i *.hpp

cpplint: cppformat
	clang-tidy --config-file=.clang-tidy --warnings-as-errors=* --quiet *.cpp -- -Wall -Wextra -Werror -std=c++98

hpplint: hppformat
	clang-tidy --config-file=.clang-tidy --warnings-as-errors=* --quiet *.hpp -- -Wall -Wextra -Werror -std=c++98

.PHONY: cppformat hppformat cpplint hpplint

4. Run Linter

Use the following commands to automatically format your code and run static analysis:

• Check .cpp files:

  make cpplint

• Check .hpp files:

  make hpplint
