Is concat an in built String helper function available that

Question

Is concat an in built String helper function available that can be used in response templating Could not see this here <https docs wiremock io response templating string helpers > or join is the function that should be used to perform concatenation

I haven t looked at `join` before today but I am not sure it is the helper you are looking for It looks like it uses the last parameter as the separator between the other parameters passed in For example this template fragment generates ``` foo join Foo Bar Baz ``` Generates this result ``` foo FooBazBar ``` I get an error when I try and pass in an empty string as the last parameter which would have been a nice solution Can you give us a little more context as to what you are trying to achieve to see if we can help find a solution Can you share your mapping and a request to use with it

For example if your use case is simple and you are just trying to concat two values together you could try something like this With a request like this ``` first Hello second World ``` Using this mapping file ``` name concat request url concat method GET response status 200 jsonBody result jsonPath request body $ first jsonPath request body $ second headers Content Type application json transformers response template ``` It should generate a result like this ``` result Hello World ``` No special helper needed with this example

Thanks a lot < Lee Turner> for the guidance I received a reply from Tom in a previous thread that I had initiated in this context My use case is listed there I was trying to change the offset in date at runtime

Ah nice Glad you got it sorted Maybe we should look at loading the concat helper in wiremock
