----------------------
local have_library, library = pcall(require, "mylibrary")
-- Do something if the library was not found, if you want
if not have_library then
print("Library was not found. Error:", library)
end
-- ... --
if have_library then
-- Use the library
library.foo("bar")
end
----------------------
You said pcall didn't work. Easy mistake to make is:
pcall(require("mylibrary")). Which is wrong, after you think about it
more :)
