* use doxygen * add documenting guide based on https://github.com/zeldaret/oot/blob/main/docs/Documenting.md * exclude stdlib readme from doxygen * refuse to configure matching iQue on macOS (EGCS compiler is not built for macOS, so iQue won't build. We still enable iQue builds on macOS by using gcc-papermario via --non-matching.) * use proper doxygen bug comment style * document common EVT API funcs nicely * add doxygen ci * add \vars command

# Documentation Style Guide
|
||
|
||
This project uses [Doxygen](https://www.doxygen.nl/index.html) to generate documentation pages from comments found in the source files. This guide focuses on writing compatible comments and ensuring consistency across the codebase.
|
||
|
||
To generate a doxygen manual for the project, ensure you have doxygen installed and then cd into the project root directory and run `doxygen`.
|
||
|
||
## Documenting Functions
|
||
For functions, a description of the function's purpose should go above the function:
|
||
```c
|
||
/// Creates a foo.
|
||
void foo(void);
|
||
```
|
||
Further considerations:
|
||
- Any comments inside the function should follow the usual `//` or `/**/` comment styles.
|
||
- For documenting return values, place a `@return` at the bottom of the function comment followed by the description of the return value. This should only be done if the name of the function is not self-explanatory and is well-understood.
|
||
- For documenting parameters, place a `@param` between the comment and the @return (if applicable) followed by the name of the parameter and a brief description. This should only be done if the name of the parameter is not self-explanatory and is well-understood.
|
||
- All `@param`s should come before `@return` and be in the same order the parameters appear in the function declaration. Note that this does not mean you should add empty `@params` for parameters deemed self-explanatory.
|
||
|
||
A full example would be as follows: (however in practice functions such as this would be considered self-explanatory)
|
||
```c
|
||
/// A cool function that multiplies a number by 2.
|
||
/// @param bar the input
|
||
/// @return bar multiplied by 2
|
||
s32 foo(s32 bar) {
|
||
return 2*bar;
|
||
}
|
||
```
|
||
|
||
## Documenting EVT API Functions
|
||
Use `@evtapi` to mark functions as EVT API functions, and use `@param` to document the parameters as passed to `EVT_CALL`. Do not use `@return`. See [include/script_api/common.h](../include/script_api/common.h) for examples.
|
||
|
||
## Documenting Variables
|
||
Documentation of variables should include what this variable is used for if the name is not completely clear and if applicable whether a set of defines or enumerations should be used alongside it (which should be linked with `@see`, see below)
|
||
```c
|
||
/// My description of this variable.
|
||
s32 foo;
|
||
```
|
||
|
||
## Documenting Files
|
||
File documentation should go near the top of the file, below includes. It should only feature information that is general to the file.
|
||
```c
|
||
/// @file file_name.c
|
||
/// My description of this file.
|
||
```
|
||
|
||
## Documenting Fields
|
||
Struct fields can be documented in the same way as variables, but you may prefer to document them in an end-of-line comment instead.
|
||
|
||
## Other
|
||
|
||
### Documenting Bugs:
|
||
Bugs should be documented on the line above where the bug begins.
|
||
```c
|
||
/// @bug description
|
||
```
|
||
### Linking related information:
|
||
`@see` should be used to provide links to related information where appropriate, for example:
|
||
```c
|
||
/// Savefile data.
|
||
/// @see SaveContext
|
||
SaveContext gSaveContext;
|
||
```
|
||
In the case of functions, `@see` should come before the first `@param`.
|
||
### Markdown
|
||
You can use Markdown in your doc comments.
|
||
### LaTeX
|
||
You can embed [LaTeX](https://wikipedia.org/wiki/LaTeX) in your doc comments if useful to do so.
|
||
|
||
For inline rendering:
|
||
```c
|
||
/**
|
||
* \f$ \textrm{Your LaTeX Here} \f$
|
||
*/
|
||
```
|
||
For centered rendering on a separate line:
|
||
```c
|
||
/**
|
||
* \f[ \textrm{Your LaTeX Here} \f]
|
||
*/
|
||
```
