The Workflows syntax supports a string data type with UTF‑8encoding (maximum length).

For information on conversion and built-in string functions, seeData types, functions, operators.

For other text processing functions, see the Workflows standardlibrarytext module reference.

Assign a string variable

The value of a static string can be assigned to a variable. For example:

-step:assign:-string:"hello"

[{"step":{"assign":[{"string":"hello"}]}}]

Concatenate using expressions

You can dynamically concatenate strings using expressions and the+ operator.For example:

-step:assign:-outputVar:${"Hello, " + firstName}

[{"step":{"assign":[{"outputVar":"${\"Hello \" + firstName}"}]}}]

Concatenate over multiple lines

Since each assignment is processed sequentially, you can concatenate a stringover multiple lines by repeating the variable and splitting the assignment. Forexample:

main:steps:-assign_vars:assign:-concatLines:"say"-concatLines:${concatLines+" "+"hello"}-concatLines:${concatLines+" "+"to the world"}-returnOutput:return:${concatLines}

{"main":{"steps":[{"assign_vars":{"assign":[{"concatLines":"say"},{"concatLines":"${concatLines+\" \"+\"hello\"}"},{"concatLines":"${concatLines+\" \"+\"to the world\"}"}]}},{"returnOutput":{"return":"${concatLines}"}}]}}
