Interpolation

String interpolation is a native feature of togomak. It uses similarly named functions from Terraform, and has a lot of helper scripts to achieve the same.

Let's take an example:

stage "hello_world" {
    script = "echo ${upper('hello world')}"
}

The above stage prints HELLO WORLD to standard output, thanks to the upper helper function.

Similarly, you can even do math!

stage "i_can_calculate" {
    script = "echo 1 plus 2 is ${1 + 2}"
}

For an incomplete list of functions, take a look at the detailed functions page.
