removefirst helper

Tom Santiago
Updated

Removes only the first occurrence of a specified substring from the input string. Use it when you need to eliminate the first match while preserving any additional instances.

Usage

{{removefirst str substring}}

  • str: input string

  • substring: substring to remove

Examples

  1. Remove the first occurrence of a character

    {{removefirst record.text "a"}}

    Input:

    { "record": { "text": "a b a b a b" } }

    Output:

     b a b a b

  2. Remove the first word in a sentence

    {{removefirst record.note "Order"}}

    Input:

    { "record": { "note": "Order Order Order" } }

    Output:

     Order Order

Tip

  • Only the first match is removed; all later occurrences remain unchanged.

  • Removal is case-sensitive—"A" and "a" are treated differently.

  • Use this helper when cleaning up values with a predictable first marker or prefix.
