Text helpers

Text helpers transform text content in Handlebars expressions.

Limit string length (Truncate)

truncate — Limits string length.

Properties

  • string — The string, string variable, or expression that produces a string whose length you want to limit.
  • max_length — An integer representing the maximum string length.
  • replacement_suffix — An optional string you want to append to the end of the truncated string if, and only if, Airship truncates the string.
Format Example Output
{{truncate <string> <max_length> [replacement_suffix]}} How did you like your{{truncate product_name 5 "..."}}? How did you like your produ…?
 Note

The max_length includes the replacement suffix, so if you set a max_length of 8, and a replacement_suffix with 3 characters (e.g. ...), Airship will only display 5 characters from a truncated string; the remaining 3 characters of any truncated string are consumed by the replacement_suffix.

For example, if you have an attribute ID name with value yourname, {{truncate name 7 "---"}} would resolve to your---. Without the suffix, the same property would truncate to yournam.

Replace

$replace — Replaces all occurrences of searchFor with replaceWith in string target.

Properties

  • target — The string or user-specific variable to be searched.
  • searchFor — A string within the target to be changed.
  • replaceWith — The intended change to target if searchFor returns true.
  • limit — Optional. Replaces only the first X occurrences.
Format Example Output
{{$replace target searchFor replaceWith [limit=<number_expression>]}} {{$replace "Some terrible jawn." "terrible" "cool"}} Some cool jawn.

  • limit — The maximum number of splits to perform.

["a", "b,c"]

Join

$join — Joins an array target using a given string delimeter, outputting a single string.

Properties

  • target — The array to be joined. An error will be thrown if this parameter is any type other than an array.
  • delimeter — A string to insert between the elements in the target array.
Format Example Output
{{$join target delimeter}} {{$join ($array "red" "green" "blue") "-"}}
