Aug 01, 2016 · Lua is a very, very small language. If you already have programming experience it should take you a few days to learn about all language features, including the (very limited) standard library.
This book tries to give you a guide to start your own experiments into the wonderful world of Wireshark development. Developers who are new to Wireshark often have a hard time getting their development environment up and running. This section describes C API data structures other than those used for prepared statements. For information about the latter, see Section 23.7.8, “C API Prepared Statement Data Structures”. Calling Go functions from LUA. A few days ago, I came across an interesting article, Calling Go Functions from Other languages.In it, Vladimir Vivien creates a small shared library in Go, which he then invokes from C, Java using Java Native Access, and from Python, Node, Ruby using Foreign Function Interface libraries. Minetest is a computer game inspired by Minecraft, Infiniminer and others. It's licensed under the GNU LGPL 2.1, with artwork generally covered by CC BY-SA 3.0. There are two major parts to the system, the first being a core engine written in C++, the second being a modding API that exposes useful functions to a Lua environment. This is why it makes sense to write the int_select function above in Lua instead of C: it keeps the Lua VM running, so Lua interrupt handlers can be executed. Interrupt handlers in C The interrupt subsystem has also a basic C API that can be used to implement portable eLua components and modules. Redis modules have two different APIs in order to access the Redis data space, one is a low level API that provides very fast access and a set of functions to manipulate Redis data structures. The other API is more high level, and allows to call Redis commands and fetch the result, similarly to how Lua scripts access Redis.
Redis scripting has support for MessagePack because it is a fast and compact serialization format with a simple to implement specification. I liked it so much that I implemented a MessagePack C extension for Lua just to include it into Redis. Since lua_State is an encapsulated environment, we need a way to pass data between lua_States, just like how we pass data in Lua between coroutines. The data passing is achieved with lua_xmove. It just simply copy n values on the stack from from to to. Learn Lua in X minutes ... •Tables implement most data structures in a simple and efficient way •records: syntactical sugar t.x for ...

If you use an Objective-C API that needs to process your data, or you need to fit your data model into an existing class hierarchy defined in an Objective-C framework, you might need to use classes and class inheritance to model your data. For example, many Objective-C frameworks expose classes that you are expected to subclass. Each Manager is a functionally related API, defining sets of data structures and functions to manipulate them. Managers are often interdependent or layered. Carbon consists of a broad set of functions for managing files, memory, data, the user interface, and other system services.
