with ".license" files, for now we define these licences using the

Raw Blame History

module: [kind=event] key_up see: keys For a lookup table of the given keys.

Fired whenever a key is released (or the terminal is closed while a key was being pressed).

This event returns a numerical "key code" (for instance, F1 is 290). This value may vary between versions and so it is recommended to use the constants in the @{keys} API rather than hard coding numeric values.

Return values

  1. @{string}: The event name.
  2. @{number}: The numerical key value of the key pressed.

Example

Prints each key released on the keyboard whenever a @{key_up} event is fired.

while true do
  local event, key = os.pullEvent("key_up")
  local name = keys.getName(key) or "unknown key"
  print(name .. " was released.")
end
