This note will be removed when -> consensus is reached. - -Not all existing code will comply with this style guide, but new code should. -Further, it is a goal to eventually update all existing code to be in -compliance. - -## All code - -### Early exit - -All code, unless it substantially increases the line count or complexity, should -use early exits from loops and functions where possible. - -## Go specific - -All Go code should comply with the [Go Code Review Comments][gostyle] and -[Effective Go][effective_go] guides, as well as the additional guidelines -described below. - -### Mutexes - -#### Naming - -Mutexes should be named mu or xxxMu. Mutexes as a general rule should not be -exported. Instead, export methods which use the mutexes to avoid leaky -abstractions. - -#### Location - -Mutexes should be sibling fields to the fields that they protect. Mutexes should -not be declared as global variables, instead use a struct (anonymous ok, but -naming conventions still apply). - -Mutexes should be ordered before the fields that they protect. - -#### Comments - -Mutexes should have a comment on their declaration explaining any ordering -requirements (or pointing to where this information can be found), if -applicable. There is no need for a comment explaining which fields are -protected. - -Each field or variable protected by a mutex should state as such in a comment on -the field or variable declaration. - -### Unused returns - -Unused returns should be explicitly ignored with underscores. If there is a -function which is commonly used without using its return(s), a wrapper function -should be declared which explicitly ignores the returns. That said, in many -cases, it may make sense for the wrapper to check the returns. - -### Formatting verbs - -Built-in types should use their associated verbs (e.g. %d for integral types), -but other types should use a %v variant, even if they implement fmt.Stringer. -The built-in `error` type should use %w when formatted with `fmt.Errorf`, but -only then. - -### Wrapping - -Comments should be wrapped at 80 columns with a 2 space tab size. - -Code does not need to be wrapped, but if wrapping would make it more readable, -it should be wrapped with each subcomponent of the thing being wrapped on its -own line. For example, if a struct is split between lines, each field should be -on its own line. - -#### Example - -```go -_ = exec.Cmd{ - Path: "/foo/bar", - Args: []string{"-baz"}, -} -``` - -## C++ specific - -C++ code should conform to the [Google C++ Style Guide][cppstyle] and the -guidelines described for tests. - -[cppstyle]: https://google.github.io/styleguide/cppguide.html -[gostyle]: https://github.com/golang/go/wiki/CodeReviewComments -[effective_go]: https://golang.org/doc/effective_go.html |
