Sorting in lua - specifying your own sort routine
In Lua, the table.sort function allows you to sort a table and by default is sorts into the order that's given back by the < operator on each of the objects to be sorted. If you want to override this behaviour, you can pass the name of a function into Lua's sort and it will call this function each time a comparison is needed. In order to help demonstrate this, I wrote a sample program with my own sort routine which I called "mysort" - as a direct replacement for table.sort with two parameters - table and function. You can see the source code here. (written 2008-07-05 19:25:18) Associated topics are indexed under U105 - Lua - Tables and the table library.U106 - Lua - Functions.
