# 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.
|
|
```diff
|
|
- Note -
|
|
As the codebase is constantly changing, only document what is complete, well-understood and not
|
|
already covered by good naming. This is especially true for function parameters and return values.
|
|
Also note that there is no obligation to completing the documentation steps for functions you
|
|
work on if you do not want to at the time.
|
|
```
|
|
To generate a doxygen manual for the project, ensure you have doxygen installed and then cd into the project root directory and run `doxygen Doxyfile`.
|
|
|
|
## Documenting Functions
|
|
For functions, a description of the function's purpose should go above the function:
|
|
```c
|
|
/**
|
|
* My description of this function
|
|
*/
|
|
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
|
|
/**
|
|
* This is an example
|
|
*
|
|
* @param bar the input
|
|
* @return bar multiplied by 2
|
|
*/
|
|
s32 foo(s32 bar) {
|
|
return 2*bar;
|
|
}
|
|
```
|
|
|
|
## 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
|
|
*/
|
|
```
|
|
|
|
## 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
|
|
/**
|
|
* Save File Data
|
|
* @see SaveContext
|
|
*/
|
|
SaveContext gSaveContext;
|
|
```
|
|
In the case of functions, `@see` should come before the first `@param`.
|
|
### HTML
|
|
You can include html tags in your doc comments, however it is strongly advised against doing this if it greatly reduces readability of the code comments.
|
|
```c
|
|
/**
|
|
* My<br>
|
|
* Newline<br>
|
|
* Doc Comment
|
|
*/
|
|
```
|
|
### 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]
|
|
*/
|
|
```
