Concatenate pairwise¤

Concatenates the values of multiple inputs pairwise.

Examples¤

Notation: List of values are represented via square brackets. Example: [first, second] represents a list of two values “first” and “second”.

Values of two inputs are concatenated pairwise:

  • Input values:

    1. [a, b, c]
    2. [1, 2, 3]

  • Returns: [a1, b2, c3]

More than two inputs are supported as well:

  • Input values:

    1. [a, b, c]
    2. [1, 2, 3]
    3. [x, y, z]

  • Returns: [a1x, b2y, c3z]

If one of the inputs has more values than the other, its remaining values are ignored:

  • Input values:

    1. [a, b, c]
    2. [1, 2]

  • Returns: [a1, b2]

Empty input leads to empty output:

  • Returns: []

A single input is just forwarded:

  • Input values:

    1. [a]

  • Returns: [a]

Parameter¤

Glue¤

Separator to be inserted between two concatenated strings. The text can contain escaped characters \n, \t and \ that are replaced by a newline, tab or backslash respectively.

  • ID: glue
  • Datatype: string
  • Default Value: None

Advanced Parameter¤

None

  • concat — Concatenate pairwise matches values by position and produces one combined string per position. Concatenate does not align by position — it produces every combination of values across inputs, so two inputs with three values each yield nine strings, not three.
  • zip — When inputs have unequal lengths, Concatenate pairwise drops the extra values from the longer input. Zip solves the same alignment problem for exactly two inputs but keeps them by substituting a configurable placeholder for each missing value.
