Are there any stl implementations for lua? I understand we can use table instead of the stl facilities when programming in lua,but it is really not friendly to be used,so I am wondering the stl implementations in lua,especially the vector,map,list,set.

    No, and rightfully so. The concepts from the STL translate very badly over to a dynamically typed language like Lua. Embrace the flexibility offered by tables and try to understand how to use their specific strengths to work efficiently and you will probably not miss it much.

    What operations on which structures are you having trouble with?

    Vector/list: use tables with numeric keys. Map: tables with any keys. Set: tables with the set contents as keys and a placeholder value (like true) as values.

  • @Schollii The STL is more than just containers.

A library exists to use C++ containers in Lua. See :

But you can also use containers written in pure Lua :

People in comments recommend you to use the Lua table structure as you need. If you need only simple data types and algorithms (for instance set with insertion, removal and test), you should. But if you need more complex algorithms, these libraries are a good choice.
