Formatting

Automated code formatting keeps your code consistent and readable. It's also a great way to avoid arguments about code style (bikeshedding).

I almost never start a new project without enforcing automated code formatting.

For example, this is technically valid:

func main() {
	fmt.Println("hello world!") }

But it's not formatted according to standard conventions. You would normally write it like this:

func main() {
    fmt.Println("hello world!")
}

go fmt

The go fmt command formats Go code. It's built into the Go toolchain, so you don't need to install anything additional to use it.

I have configured my editor to auto-format my code on save, so my code is always formatted. The default "Notely" project should already be formatted properly, so let's break it so that we can see how go fmt works.

Assignment

While still on your addtests branch, edit one of the functions in the Notely codebase so that it's not formatted properly. For example, you could remove the whitespace between the function parentheses and body:

func main() {
vs
func main(){

Save the file without autoformatting it (you might need to get around auto-formatting if your editor does it automatically).
Run go fmt ./... in the root of your project. You should see the code get formatted properly.

Run and submit the CLI tests from the root of your repo.
