* **Documentation** * Added new C coding style guide detailing naming conventions for files, directories, macros, constants, variables, functions, and type definitions with illustrative examples. * Updated C++ coding style documentation with clarifications on C naming conventions and header directory organization patterns. * **Refactor** * Updated header include paths throughout the codebase to use lowercase naming conventions consistently.

# C++ coding Style
|
|
|
|
The basic formatting rules are set in `.clang-format`. Use auto-formatting in your editor.
|
|
|
|
All code should target C++ language revision 20.
|
|
|
|
If you use CLion, please enable the setting called "Enable ClangFormat" under Settings > Editor > Code Style.

# C projects with C++ code
|
|
|
|
In projects that expose a C API with internal C++ code, the C naming conventions are used for language features that are shared.
|
|
|
|
## Naming
|
|
|
|
### Files
|
|
|
|
Files are upper camel case.
|
|
|
|
- Files: `^[0-9a-zA-Z]+$`
|
|
- Directories: `^[0-9a-zA-Z]+$`
|
|
|
|
Example:
|
|
```c++
|
|
SomeFeature.cpp
|
|
SomeFeature.h
|
|
```
|
|
|
|
Private/internal headers are placed in a `Private/` directory.
|
|
|
|
### Folders
|
|
|
|
Project folders include:
|
|
- `Source` for source files and public header files
|
|
- `Private` for private header files
|
|
- `Include` for projects that require separate header files
|
|
|
|
Sources for a specific namespace must go into a folder with the lowercase name of that namespace.
|
|
The only exception to this is the root namespace, as this doesn't require its own subfolder.
|
|
|
|
### Function names
|
|
|
|
Names are lower camel case.
|
|
|
|
Example:
|
|
|
|
```c++
|
|
void getLimit() {
|
|
// ...
|
|
}
|
|
```
|
|
|
|
### Type names
|
|
|
|
Consts are lower camel case with capital letters.
|
|
|
|
Typedefs for structs, classes and datatype aliases are upper camel case.
|
|
|
|
Examples:
|
|
|
|
```c++
|
|
typedef uint32_t ThreadId;
|
|
|
|
const ThreadId id;
|
|
|
|
struct ThreadData {
|
|
// ...
|
|
};
|
|
```
|
|
|
|
### Enumerations
|
|
|
|
`enum class` or `enum struct` is preferred over plain `enum` because of scoping. It's styled like this:
|
|
|
|
```c++
|
|
enum class SomeType {
|
|
Ok,
|
|
NotSupported,
|
|
Error
|
|
};
|
|
```
|
|
|
|
### Exceptions
|
|
|
|
Don't ever throw them. Make a return type that wraps all the error and success scenarios that are relevant.
