Assigning Scratch variable values to non Scratch variables

support

Hi there,

I’m new to Hugo, and I find that a major pain point of working with templates is the inability to assign values to existing variables. For example,

{{ $foo := "Hello" }}
{{ $foo = "world" }} // THIS DOESN'T WORK!
{{ $foo }}

does not work. However, I noticed the very handy Scratch function, which allows operations like this:

{{ $.Scratch.Add "foo" "Hello"}}
{{ $.Scratch.Set "foo" "world"}}
{{ $.Scratch.Get "foo" }} //Outputs "world"

However, I have a use case where I’d want to use the value of $foo in the Scratch scope. I’ve tried {{ $bar := $.Scratch.Get "foo"}}, but this doesn’t seem to be possible. Is there a way to extract the value of a Scratch variable? Or even better, a way to re-assign values to variables in the templates? Thank you.

That syntax should work fine (I use it in several places). Can you post an example where it isn’t working for you?

@jgreely thanks so much for the response. Turns out for some reason my build wasn’t autoupdating (I think my drafts flag was off when I started the server, and I’d changed my post to be a draft). That syntax does indeed work. Sorry for the trouble, but thanks again, much appreciated.
