Coxpcall http://keplerproject.github.io/coxpcall/ Coxpcall encapsulates the protected calls with a coroutine based loop, so errors can be dealed without the usual pcall/xpcall issues with coroutines for Lua 5.1. Using Coxpcall usually consists in simply loading the module and then replacing Lua pcall and xpcall by copcall and coxpcall. Coxpcall is free software and uses the same license as Lua 5.1. Coxpcall can be downloaded from its GitHub page. You can also get Coxpcall using LuaRocks: luarocks install coxpcall Lua 5.2 was extended with the Coxpcall functionality and hence it is no longer required. The 5.2 compatibility by coxpcall means that it maintains backward compatibility while using the build in 5.2 implementation.
