Concatenates a set of strings.

The concat plugin is used to concatenate strings. For example, imploding a set of strings into a single string.

Available configuration keys:

  • delimiter: (optional) A delimiter, or glue string, to insert between the strings.

Examples:


process:
  new_text_field:
    plugin: concat
    source:
      - foo
      - bar

This will set new_text_field to the concatenation of the 'foo' and 'bar' source values. For example, if the 'foo' property is "Rosa" and the 'bar' property is "Parks", new_text_field will be "RosaParks".

You can also specify a delimiter.


process:
  new_text_field:
    plugin: concat
    source:
      - foo
      - bar
    delimiter: /

This will set new_text_field to the concatenation of the 'foo' source value, the delimiter and the 'bar' source value. For example, using the values above and "/" as the delimiter, if the 'foo' property is "Rosa" and the 'bar' property is "Rosa", new_text_field will be "Rosa/Parks".
