# Code Style
## Naming Convention
- Files: `snake_case.h` `snake_case.cpp`
- Namespaces: `CamelCase`
- Classes: `CamelCase`
- Structs: `CamelCase_t`
- Members: `camelCase`
- Enum: `SNAKE_CASE`
- Macros: `SNAKE_CASE`
## Brace Style
```c++
int myFunction() {
if (shortIf) { shortFunctionName(); }
if (longIf) {
longFunction();
otherStuff();
myLongFunction();
}
}
```
Note: If it makes the code cleaner, remember to use the `?` keyword instead of a `if else` statement.
## Pointers
Please use `type* name` for pointers.
## Structure
Headers and their associated C++ files shall be in the same directory. All headers must use `#pragma once` instead of other include guards. Only include files in a header that are being used in that header. Include the rest in the associated C++ file.
# Modules
## Module Naming Convention
All modules names must be `snake_case`. If the module is a source, it must end with `_source`. If it is a sink, it must end with `_sink`.
For example, lets take the module named `cool_source`:
- Directory: `cool_source`
- Class: `CoolSourceModule`
- Binary: `cool_source.<os dynlib extension>`
## Integration into main repository
If the module meets the code quality requirements, it may be added to the official repository. A module that doesn't require any external dependencies that the core doesn't already use may be enabled for build by default. Otherwise, they must be disabled for build by default with a `OPT_BUILD_MODULE_NAME` variable set to `OFF`.
