# Clay SDL3 Template
|
||||
|
||||
## Using Template
|
||||
|
||||
### Just use [`just`](https://just.systems/man/en/)
|
||||
|
||||
Run `just set-project-name {project name}` first.
|
||||
|
||||
And remember to `git remote set-url origin {repo}`.
|
||||
|
||||
### Otherwise
|
||||
|
||||
Modify the CMakeLists.txt manually, just replace CHANGEME with whatever your binary should be called.
|
||||
|
||||
## Compiling
|
||||
|
||||
> Remember to `git submodule update --init --recursive`!
|
||||
|
||||
### Just again
|
||||
|
||||
`just configure` runs cmake configuration and generates a `compile_commands.json`.
|
||||
|
||||
`just build` runs the cmake build.
|
||||
|
||||
### CMake works too, I guess
|
||||
|
||||
`cmake -S. -Bbuild`
|
||||
|
||||
`cmake --build build`
|
||||
|
||||
Same as always
|
||||
|
||||
## Files
|
||||
|
||||
### thread_pool.h/cpp
|
||||
|
||||
Thread pool used for parallel GoL generation ticking.
|
||||
|
||||
### application.h/cpp
|
||||
|
||||
UI and layout logic.
|
||||
|
||||
### style.h/cpp
|
||||
|
||||
Reusable UI styling
|
||||
|
||||
### resources.h/cpp
|
||||
|
||||
Font loading.
|
||||
|
||||
### elements.h/cpp
|
||||
|
||||
Reusable UI elements
|
||||
|
||||
### input.h/cpp
|
||||
|
||||
Handling of input events.
|
||||
|
||||
### main.cpp:
|
||||
|
||||
Entrypoint, setup, and main application loop.
|
||||
|
||||
## Prerequisites
|
||||
|
||||
* CMake 3.21 or higher
|
||||
|
||||
* Compiler capable of C++23 and C23.
|
||||
|
||||
## 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.
|
||||
|
||||
> Note: Mildly modified from the official Clay_SDL3_renderer to enable more advanced styling.
|
||||
|
||||
## Code Standards
|
||||
|
||||
* Keep program structure as simple as possible. No `class 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. `Type const &Function(Type &inRef)`
|
||||
|
||||
> (1) Bracket exceptions:
|
||||
> * using scoped_lock in arbitrary blocks, prefer tailed lisp brackets
|
||||
|
||||
```
|
||||
struct Data {
|
||||
int x{ 0 }, y{ 0 };
|
||||
};
|
||||
void MyFunction(Data const &data) { // K&R here
|
||||
DoAsynchronousThings();
|
||||
{ scoped_lock lock{ myMutex };
|
||||
myVariable++;
|
||||
} // not quite lisp, lisp with a tail
|
||||
DoMoreAsynchronousThings();
|
||||
}
|
||||
```
