Continue statements

August 12, 2024

Let’s continue… haha

See what I did there?

Bleh, okay.

Continue statements

A “continue” statement begins the next iteration of the innermost enclosing “for” loop by advancing control to the end of the loop block. The “for” loop must be within the same function.

ContinueStmt = "continue" [ Label ] .

There’s not a lot necessary to say here. continue works very much like break. The scoping rules are essentially the same.

The only differences:

  • continue only works in a for loop. It doesn’t apply to switch or select statements.
  • Because it doesn’t apply to switch or select statements, you only need to use a label with nested for loops.
  • Rather than terminating the loop, it jumps to the next iteration.

If there is a label, it must be that of an enclosing “for” statement, and that is the one whose execution advances.

RowLoop:
	for y, row := range rows {
		for x, data := range row {
			if data == endOfRow {
				continue RowLoop
			}
			row[x] = data + bias(x, y)
		}
	}

Break statements with labels

Break statements … If there is a label, it must be that of an enclosing “for”, “switch”, or “select” statement, and that is the one whose execution terminates. In other words, you can’t break to a label that labels a more deeply nested for, switch or select statement, or to one that’s completely unrelated. But that’s only intuitive, right? OuterLoop: for i = 0; i < n; i++ { for j = 0; j < m; j++ { switch a[i][j] { case nil: state = Error break OuterLoop case item: state = Found break OuterLoop } } } Speaking of labels, did you know that you can have blank labels?


Break statements

Break statements A “break” statement terminates execution of the innermost “for”, “switch”, or “select” statement within the same function. BreakStmt = "break" [ Label ] . We’ll discuss the Label mentioned tomorrow. Until then, the key word here is innermost. This shouldn’t be very surprising to anyone familiar with other programming languages. But despite its familiarity, I’ve been bitten more than once by forgetting this key detail. It’s perhaps easiet to forget when you have, say, a switch statement within a for loop, for example.


Terminating labeled statements

Today’s live stream is starting an hour later than usual. Join me at 16:00, CEST, for some live Go coding using TDD. Terminating statements … A labeled statement labeling a terminating statement. Labeled statement’s are not used a lot in Go. Terminating labeled statements even less so. But they do exist, just the same. Here’s an example, using goto, and a labeled terminating statement. func foo() { if someCondition { goto end } fmt.
