What are the common Go formatting and style conventions?

Go, often referred to as Golang, has a set of formatting and style conventions that help maintain readability and consistency in code. Here are some common conventions:

  • Package Names: Package names should be lower case and should not use underscores or mixed caps. Example: package mypackage
  • Function Names: Function names should be concise and use CamelCase; exported functions should start with an uppercase letter. Example: func MyFunction() {}
  • Variables: Use short variable names in small scopes; longer names are acceptable in larger scopes. Example: var x int
  • Commenting: Use comments to explain why, not what. All exported entities should have comments, starting with the name of the entity. Example: // MyVariable is an example variable.
  • Formatting: Use `gofmt` to format your code automatically. This keeps the style consistent across all Go codebases.
  • Control Structures: Don't use parentheses around conditions in control structures. Example: if x > 0 {}
  • Error Handling: Handle errors properly. Always check the error returned from functions. Example: if err != nil { return err }
