Is '\n' the Best Approach for Cross-Platform Newline Representation in Go?

Cross-Platform Newline Representation in Go/Golang

When representing newlines in Go programs, the most prevalent approach is to use the "n" escape sequence. However, this begs the question of whether this method is truly suited for cross-platform development.

In some languages, such as PHP, newlines are represented using a global constant like PHP_EOL. This prompts us to ponder: is "n" the most appropriate way to denote newlines in a cross-platform context within Go?

Behind the Scenes of fmt.Println

To shed light on this matter, we delve into the inner workings of fmt.Println. As you scroll down its source code (http://golang.org/src/pkg/fmt/print.go), you'll encounter an if addnewline block where "n" is consistently used. While this is evidence of the widespread adoption of "n", it's crucial to note that this isn't necessarily the most cross-platform approach.

Alternative Options and Considerations

An alternative strategy to using "n" is leveraging fmt.Fprintln. This approach still holds merit because if the current implementation is found inadequate, one could file a bug and update their code to utilize the latest Go toolchain.

Ultimately, the choice between "n" and fmt.Fprintln depends on the specific requirements and sensitivities of your cross-platform project.
