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…? |
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.
