String Parser

Function processing input strings

Evaluation

This expression evaluates to a function of the form:

(string x) -> string

The function is consistent with parser semantics used for string to data conversion, for example by the CSV Input step.

If trimming is enabled, whitespace is trimmed from beginning and end of x.

If x is equal to the configured nil value, nil is returned.

If x is nil, nil is returned.

Name Type Description

Name	Type	Description
Trim	boolean	If `true`, whitespace from both ends of the string is trimmed before processing. If `false`, the given string is returned unaltered.
Nil Value	datetime	A single string or a list of strings representing `nil` values. If `x` is equal to any of them, the result is `nil`.

boolean
