Input Validation

Input validation restricts prompt inputs using regular expressions, online player checks, or JavaScript expressions.

To use input validation:

1. Define a validator in prompt-config.yml under Input-Validation.

2. Apply it using the -iv:<alias> prompt flag.

Configuration Example (prompt-config.yml)

Input-Validation:
  Integer-Sample:
    Alias: is
    Regex: '^\d+'
    Err-Message: '&cPlease enter a valid integer!'
  Alpha-Sample:
    Alias: ss
    Regex: '[A-Za-z ]+'
    Err-Message: '&cInput must only consist of letters!'
  Online-Validator:
    Alias: ov
    Online-Player: true
    Err-Message: '&cThat player is not online!'

Usage

Apply the validator to a prompt using -iv:<alias>:

/command <Enter integer -iv:is> <Enter letters -iv:ss> <Enter online player -iv:ov>

If validation fails, the Err-Message is sent to the player, and the prompt is re-displayed.
