Here are the conventions:
- We use C++17.
- - All new public functions in all classes need documenting comments on what they do and what behavior they follow, use doxy-comments formatted as `/** Description */`. Do not use asterisks on additional lines in multi-line comments.
+ - Please use **tabs for indentation and spaces for alignment**. This means that if it's at line start, it's a tab; if it's in the middle of a line, it's a space.
+ - All functions in all classes need documenting comments on what they do and what behavior they follow, use doxy-comments formatted as `/** Description */`. Do not use asterisks on additional lines in multi-line comments.
- Use spaces after the comment markers: `// Comment` instead of `//Comment`. A comment must be prefixed with two spaces if it's on the same line with code:
- `SomeFunction()<Space><Space>//<Space>Note the two spaces prefixed to me and the space after the slashes.`
- All variable names and function names use CamelCase style, with the exception of single letter variables.
- `ThisIsAProperFunction()` `This_is_bad()` `this_is_bad()` `GoodVariableName` `badVariableName`.
- - All member variables start with `m_`, all function parameters start with `a_`, all class names start with `c`.
+ - All private member variables start with `m_`, function parameters start with `a_`, class names start with `c`.
- `class cMonster { int m_Health; int DecreaseHealth(int a_Amount); }`
- - Function parameters that are coordinates should be passed using an appropriate storage container, and not as three separate arguments.
- - e.g. for a block position, Vector3i. For an entity position, Vector3d. For a chunk coordinate, cChunkCoords.
- - For a 3-dimensional box of blocks, use cCuboid. For an axis-aligned bounding box, use cBoundingBox.
- - Parameters smaller than 4 elements (e.g. Vector3, cChunkCoords) should be passed by value. All other parameters should be passed by const reference, where applicable.
- - `Foo(Vector3d a_Param1, const cCuboid & a_Param2)`
- - See the discussion in issue #3853
- Put spaces after commas. `Vector3d(1, 2, 3)` instead of `Vector3d(1,2,3)`
- Put spaces before and after every operator, except unary operators.
