Using this as ref doc <https docs wiremock io response templating dates and times > for the example ``` now offset= 3 days ``` If I need to pick the value from a variable that is defined earlier instead of a fixed number 3 in this example what are the ways to do that Further if this variable needs to coming from a loop index where index is changing with each iteration in the loop is that possible

You can use the `concat` helper to build the offset string e g ``` now offset= concat request query offsetDays 0 days ```

What is the right ref doc for such functions so that I don t have to borrow your valuable time for these and other helper functions Is it handlebar js ``` now offset= concat request query offsetDays 0 days ``` the above syntax seems to have some issues ```12 30 found days expected ```

Tom · Answer

This is the implementation we use <https github com jknack handlebars java>

Apologies < Rahul Agrawal> I ve misled you here Seems we re not loading the concat helper at the moment so it s not available You can use `assign` for the same purpose however ``` assign offset request query offsetDays days assign now offset=offset ```

Thanks for the help with the above code Don t worry your did not mislead me It was blessing in disguise Forced me try other options and read more the above expression seems a very elegant approach and will hep me for few other things also Rarely seen the founders paying so much attention to each query from end users to help them This is another thing to learn from you < Tom> clap
