kmCount

Returns how many items are in a list or JSON array, or keys in a record.

Keyboard Maestro: COUNT

Details #

kmCount() or kmCount(value) takes zero or one argument and returns a number.

With a value: a list or record gives its item or key count, and text is parsed as JSON first. Anything else (a number, text that isn't a JSON array or object) gives 0.

With no argument it counts the variable kmJSONArray, or failing that json, and gives 0 if neither is set.

Parameters #

Takes 0 to 1 argument. {{ kmCount(text?) }}

Examples #

kmCount(items)

→ 3

Sample variable	Value
`items`	`["a", "b", "c"]`

kmCount(text)

→ 4

Sample variable	Value
`text`	`[1, 2, 3, 4]`

Gotchas #

Text that isn't JSON counts as 0, not an error. For plain counting use length.
Keyboard Maestro's COUNT only works while evaluating a JSON path; here it is an ordinary function.
