RE: get/setglobal

["Peter Prade" <prade@...>]

the setglobal tagmethod has 3 parameters: varname, oldvalue, newvalue
and the getglobal tagmethod has 2 params: varname, value and should return a
value

hope that helps,
Peter

Hi,

i think i must be really stupid today, whats wrong
with these simple lines of code.
At the last line Hello has the value nil and so
the call fails.

Lua calls setglobal for "Hello" while executing the
function definion and i expect a value of type
"function" as second parameter but what i get is "nil".
Am i missing something here?


function GetGlobal( varname )
  print( "Get global: "..varname )
  rawget( globals(), varname )
end


function SetGlobal( varname, value )
  print( "Set global: "..varname )
  rawset( globals(), varname, value )
end


settagmethod( tag(nil), "getglobal", GetGlobal )
settagmethod( tag(nil), "setglobal", SetGlobal )


function Hello()
  print( "Hello called" )
end

Hello()


TIA,

Michael Flad
