can you give an example? __index gets a (table, n) passed and not the string itselfOn Wed, Dec 16, 2009 at 3:29 PM, Hans Hagen <pragma@wxs.nl> wrote:The following is valid lua a = "text" b = a[3]Yes, given that there is no index operator for strings it seems odd that we don't get an error. The reason is that strings have a metatable with __index pointing to the string table; looking up [3] on s leads to string[3] which gives the nil as you've noticed. If you're prepared to modify the metatable of all strings, then you can define a[3] in this case to be a:sub(3,3)
