`continue` statement in `range` block

I was just wondering if it is possible to conditionally skip an iteration inside a range.

Range conditionals are possible, but I am not sure what you need. Searching this forum for “range conditional” here is one example:

I’m looking for a way to skip an unnecessary iteration in range. For example, in Java, we can do so.

for(int i=0; i<3; i++) {
  if(i==2)
    continue;
  System.out.print(i+" ");
}

This example would output 0 1 3. Here continue skips the i=2 iteration. I’m looking for an analog for Hugo.

Your example can be rewritten as:

for(int i=0; i<3; i++) {
  if(i!=2)
    System.out.print(i+" ");
}

(IF i IS NOT 2) and does not require a continue then.

I myself know that. But there are some situations where I need continue. Does Hugo have something similar?

Hi @UtkarshVerma. I think you’ll have better luck if you give us a concrete example of what you’d like to do.

To my knowledge and the Go Template doc there is nothing equivalent to continue or break in ranges

I agree, it’s not possible. Our own Bep did make a feature request for it here, which got accepted by the Go team. :slight_smile:

In the past this feature was added, but then got reverted back because of issues.

Currently break and continue are unplanned. So it looks it may take a while. (If they were in an upcoming Go version, they move from unplanned to planned.)

use range with index

and the math functions

with if eq all is done

I myself have a workaround for that. It is exactly what @davidsneighbour had suggested. Therefore what I was looking for wasn’t a solution. It was just me asking if such a feature was present in Go or not.

Oh. Anyhow, thanks for the information.
