Coding Standards
If you want to see Launch’s history of coding standards, refer to Coding Standards (deprecated)
This page should serve as the main reference for coding standards now.
General Guidelines
In general, you can expect these rules to be the same across different languages
Indents are 4 spaces each
Curly braces will follow K&R style, meaning that the curly brace is on the same line, not newline
C Coding Standards
Variable and function names should use snake_case
Functions with no parameters should have void as a parameter
int no_param_function(void) { int some_variable = 0; return 0; }
C++ Coding Standards
Variable and function names should use camelCase
Class names should be prefixed with a “C”. The associated file should be prefixed with a “c_”.
Namespaces should be prefixed with a “N”. The associated file should be prefixed with a “n_”.
Public member functions should be capitalized
namespace Foo { class Bar { public: void Baz(); protected: void dead(); private: void beef(); } }
Python Coding Standards
Just follow PEP8
Golang Coding Standards
Follow the general standards and let gofmt worry about the rest.
