Re: read only variables

["Jose Luis Hidalgo" <joseluis.hidalgo@...>]

Hi,
May be this can help you. You can do this from C code too of course.

meta={}
meta.__newindex = function(t,v,value) print("Avoid variable
modification of "..v.." !!!") end
myvar = 6
print(myvar)
-- do the magic
setmetatable(_G,meta)
myval=5
print(myvar)

Cheers,
   Jose L.
