Created page with "== Calling Pattern == Call local km = sl.keymon(t) later keymon.refresh() == Example == local t = { ['ALT SHIFT J']= function() print('ALT SHIFT J') end, ['CTRL J'] ..."

New page

== Calling Pattern ==
Call
local km = sl.keymon(t)
later
keymon.refresh()

== Example ==

local t = {
['ALT SHIFT J']= function() print('ALT SHIFT J') end,
['CTRL J'] = function() print('CTRL J') end,
}
local km = sl.keymon(t)
while true do
km.refresh()
wait(30)
end

-> CTRL J
ALT SHIFT J
ALT SHIFT J

== Description ==

The keymon refresh method the state of every key necessary and determines which, if any, hotkey is currently pressed. The keymon generator creates a string from the given table of hotkey=handlerfunction values to quickly assess if any handler should be called and passes this to [[loadstring]]. In the example above, the created internal function looks like:

local gk = {getkey("ALT"),getkey("SHIFT"),getkey("CTRL"),getkey("J"),};
if gk[1] == true and gk[2] == true and gk[3] == false and gk[4] == true then return 1
elseif gk[1] == false and gk[2] == false and gk[3] == true and gk[4] == true then return 2
end;

The result of calling this function is used to look up and invoke the appropriate user supplied handler. Refresh takes no arguments and normally returns no values.

== Upon Error ==

If one of the hotkey handler functions throws an error during evaluation, an unhandled exception will occur. In versions 0.09+, any errors thrown will be caught at the keymon.refresh level and handled according to the operant error redirection mode.
