trim INPUT CUTSET
strings.Trim INPUT CUTSET
{{ trim "++Batman--" "+-" }} → "Batman"

trim requires the second argument, which tells the function specifically what to remove from the first argument. There is no default value for the second argument, so the following usage will not work:

1

{{ trim .Inner }}

Instead, the following example tells trim to remove extra new lines from the content contained in the shortcode .Inner variable:

1

{{ trim .Inner "\n" }}

Go templates also provide a simple method for trimming whitespace from either side of a Go tag by including a hyphen (-).
