# Conway's Game of Life SDL3 implementation
|
|
|
|
## Compiling
|
|
|
|
> Remember to `git submodule update --init --recursive`!
|
|
|
|
### Just use [`just`](https://just.systems/man/en/)
|
|
|
|
Use the justfile if you have `just` and `bear` installed:
|
|
|
|
`just configure` runs cmake configuration.
|
|
|
|
`just build` runs the cmake build and generates a `compile_commands.json` (assuming you have `bear` installed).
|
|
|
|
### CMake works too, I guess
|
|
|
|
`cmake -S. -Bbuild`
|
|
|
|
`cmake --build build`
|
|
|
|
Same as always
|
|
|
|

|
## Prerequisites
|
|
|
|
* Compiler capable of C++23 and C23.
|
|
|
|
* CMake 3.21 or higher
|
|
|
|
## Dependencies
|
|
|
|
### SDL3
|
|
|
|
Included as git submodule at `vendor/SDL3/` and dynamically linked.
|
|
|
|
### SDL3_ttf
|
|
|
|
Included as git submodule at `vendor/SDL3_ttf/` and dynamically linked.
|
|
|
|
### Clay
|
|
|
|
Included as files in `vendor/clay/clay.h`; Single header library.
|
|
|
|
### Clay SDL3 renderer
|
|
|
|
Included as files in `vendor/renderer/` and compiled as part of the project.
|
|
|
|
## Code Standards
|
|
|
|
* Keep program structure as simple as possible. No `Application` class or other Java-isms. Prefer namespaces with static lifetime variables.
|
|
|
|
* Use STL where possible. Don't reinvent the wheel.
|
|
|
|
* K&R brackets. With notable exceptions(1)
|
|
|
|
* camelCase for variables, PascalCase for types and functions (that's what SDL and Clay do).
|
|
|
|
* In class member functions, always use `this->` to access member variables.
|
|
|
|
* const applies to the name to it's left, so it goes after the type, not `const int x;` but `int const x`.
|
|
|
|
* \* and & flush with the declaration name. `void Function(Object const &inRef)`
|
|
|
|
> (1) Bracket exceptions:
|
|
> * using scoped_lock in arbitrary blocks, prefer tailed lisp brackets
|
|
```
|
|
void MyFunction() { // K&R here
|
|
DoAsynchronousThings();
|
|
{ scoped_lock lock{ myMutex };
|
|
myVariable++;
|
|
} // not quite lisp, lisp with a tail
|
|
DoMoreAsynchronousThings();
|
|
}
|
|
```
