← WoW API < print

This function is implemented in Lua here RestrictedEnvironment.lua.

Passes its arguments to the current print output handler. By default, this will output them all to the default chat frame.

print(...)

Arguments

...: Any - any number of any type of values.

Example

print("Hello, WoW!")

prints Hello, WoW!

print("Hello", "this is a", nil, "value")

(note that "nil" is not in double quotes)

prints Hello this is a nil value

print("Hello", "this is a"..nil, "value")

Throws the error, "attempt to concatenate a nil value"

print("Hello", "this is a", {}, "value")

prints Hello this is a table: ###### value

Details

This function is a securecall/forceinsecure wrapper around the current print output handler function. Instead of attempting to replace it, you can set your own output handler function using setprinthandler(func).
This function serves as a cleaner replacement from DEFAULT_CHAT_FRAME:AddMessage(); unlike which, it can safely be used to output nil values.

History

Added in 3.0.2 (8926)
