Define Liquid custom function

[DotCat1985]

Hi,
since OrchardCore render Liquid code using Fluid, how can I define and use a custom function?
See the example clicking on the link below.

In OC You can extend liquid options by adding template options in module startup

services.Configure<TemplateOptions>(o =>
            {

var lowercase = new FunctionValue((args, context) => 
{
  var firstArg = args.At(0).ToStringValue();
  var lower = firstArg.ToLowerCase();
  return new ValueTask<FluidValue>(new StringValue(lower));
});

                o.Scope.SetValue("lowercase”, lowercase);
                });
