Syntax

$isBoolean[value]

Parameters

Parameter	Description
value	The value to test. Required, exactly one argument.

Return Value

• Type: Boolean
• true if value is one of true, false, yes, no, on, off, enable, disable.
• false otherwise (number, any other text, or empty).

Behavior

• The comparison is exact and case-sensitive: TRUE, No and ` true (with a space) return false`.
• The eight words above are all accepted, including yes/no and on/off.
• 0 and 1 are not booleans (use $isNumber[] for those cases).

Examples

Validation in a condition

$if[$isBoolean[$message[1]]==true]
  $sendMessage[✅ $message[1] is a valid boolean.]
$else
  $sendMessage[❌ $message[1] is not a boolean. Expected: true or false.]
$endif

Checking a variable

$var[actif;true]
$if[$isBoolean[$var[actif]]==true]
  $sendMessage[The variable is a boolean.]
$endif

Advanced type checking

$var[val;$message[1]]
$if[$isBoolean[$var[val]]==true]
  $sendMessage[📌 Boolean detected: $var[val]]
$elseif[$isInteger[$var[val]]==true]
  $sendMessage[🔢 Integer detected: $var[val]]
$elseif[$isNumber[$var[val]]==true]
  $sendMessage[🔣 Number detected: $var[val]]
$else
  $sendMessage[📝 Text detected: $var[val]]
$endif
