### [SOLVED]Anonymous Function Scope

Yesterday a guy on IRC explained to me why this works

Code: Select all

function templates.text(text)
tmp = text
return string.dump(function()
love.graphics.printf(tmp,40,40,400)
end)
end

but this doesn't

Code: Select all

function templates.text(text)
return string.dump(function()
love.graphics.printf(text,40,40,400)
end)
end

because of the anonymous function scope.

Is there a way to do it without that stupid temporary variable? It even can not be local so that is another problem (overwriting data). There must be a way .

### Re: Anonymous Function Scope

The reason that limitation is there is because there is no good workaround. That said, what are you using string.dump for?

Oh ok. Changed the code a bit and now I do not need it anymore. I've been using string.dump in pair with loadstring.

Returning the function directly instead of the string representation solved the scope issue too. Double win.
