Hello,
I would like to sort a table of tables (sic).
To do that I was hoping to use table.sort( aTable, aComparator ), where
'aComparator' is my own function. Something like this perhaps:
-- instance method to compare the two given services
this.compare = function( anObject, anotherObject )
local aLength = string.len( anObject.prefix() )
local anotherLength = string.len( anObject.prefix() )
return aLength > anotherLength
end
Unfortunately, table.sort() throws an exception:
lua: attempt to compare two table values
stack traceback:
[C]: in function `sort'
./LU/LUList.lua:311: in function `sort'
./LWApplication.lua:74: in function `registerService'
Test.lua:15: in main chunk
[C]: ?
Why is that? Why can't I "compare two table values"? Am I doing
something wrong?
For the record, I'm using lua-5.1-work5.
Thanks :)
Cheers
