Overview
The Go standard library is a good source of code examples, comments and style.
Naming
Naming is one of the most important aspects of Go development. Writing idiomatic Go requires understanding of its core naming principles.
Identifiers should use camel case: SomeColor or someColor, depending on whether they are visible outside the package or not. Do not use snake case some_color.
Acronyms should have a consistent case. URL or url is correct, Url is not.
When a variable, struct or interface is imported from another package, its name includes the package name or alias: mypackage.MyVar.
Use name abbreviations only if they are widely used (example: fmt).
Avoid name collisions, when possible. If you introduce a set of string functions, avoid calling the package strings because a package with the same name exists in the standard library already.
