SUBSCRIBEFormatting
- In Golang formatting, the code is much easier as the machine takes care of most of the formatting issues.
- The gofmt package in Golang takes care of formatting and emits the code in standard style and in the vertical format.
Golang Formatting rules
- Indentation - Golang uses tabs for indentation and gofmt by default takes care of it.
- Line Length - Golang has no upper limit for line length. If you feel the line getting too long just use an extra tab to indent it.
- Parentheses - Golang only uses parentheses with if, for, and switch. It is much lesser than other programming languages like C, C++, and Java.
Golang Comments
Golang allows to comment the code in two ways
- C-Style /* */ Block comments.
- C++ style // line comments.
Example of Block Comment
package main
import "fmt"
/*
func main() {
fmt.Println("Hello World")
}
*/
Example of Line Comment
package main
import "fmt"
func main() {
fmt.Println("Hello World") //Line Comment
}
Semicolons
- Golang works in the same way as C works. Go by default uses semicolons to terminate statements.
- But we don't have to use semicolons while writing the code. Golang's lexer automatically inserts semicolons as it scans the code.
- Golang follows the rule to insert semicolons automatically if the last token before a new line is an identifier (like int and float64).
