Apply example in docs

support
1

In the docs for apply: https://gohugo.io/functions/apply/

The following example is given:

+++
names: [ "Derek Perkins", "Joe Bergevin", "Tanner Linsley" ]
+++

You can then use apply as follows:

{{ apply .Params.names "urlize" "." }}

Which will result in the following:

"derek-perkins", "joe-bergevin", "tanner-linsley"

But the result I get is:

[derek-perkins joe-bergevin tanner-linsley]

Is this an error on my part?

I’m surprised this worked for you. Since it’s TOML front matter, it should be names = not names:

But yes the result you get is expected. You can debug it like so:

{{ $output := apply .Params.names "urlize" "." }}
{{ $output }}

{{ printf "%#v" $output | safeHTML }}

Which will give:

[derek-perkins joe-bergevin tanner-linsley]

[]interface {}{"derek-perkins", "joe-bergevin", "tanner-linsley"}

Thanks. An error on my part regarding the TOML front matter in my post.

Just so I understand, if I would like each name to be comma separated and urlized, I would need to use a range with delimit instead of apply. Is that correct?

If you scroll further down in that apply doc, they give you the delimit example that you want

Understood. Saw it earlier, just wanted to check with the apply statement. Many thanks as always for helping out.
