Is Go's `fmt.Println` Truly Cross-Platform for Newline Representation?

Cross-Platform Newline Representation in Go

While the use of "n" to represent newlines in Go may seem intuitive, its cross-platform viability raises concerns. To gain a deeper insight, let's examine the approach used by the standard library function fmt.Println.

Digging into the source code for this function, we find that it incorporates an "if addnewline" condition where a newline character, represented by "n", is consistently added. This implementation suggests that this character is indeed the preferred representation for newlines in Go's standard library.

However, the question of whether this approach is the most cross-platform remains open. Given Go's early association with Linux, it is possible that this particular choice may be biased towards that platform.

As an alternative, the use of fmt.Fprintln has been proposed. This function allows for more flexibility in line termination, depending on the underlying platform. If the default behavior is deemed insufficient, filing a bug and recompiling with an updated Go toolchain could provide a customized solution.
