Fungw is a tiny, portable library written in C (C89) that manages dynamic function calls across different programming languages. For this, fungw provides: - a simplistic scalar data type abstraction, supporting the most common types - semi-automatic conversion between data types - contexts that can host objects; objects can host named functions - a set of optional language bindings to the most popular scripting languages The main use of fungw is to provide the host application a framework where dynamic parts of the code (e.g. plugins) can register their calls, allowing app-plugin, plugin-app, and plugin-plugin calls. The second main use is doing all this in a language-agnostic way: any part of the code can be implemented in any of the numerous supported scripting languages (such as awk or lua). The caller of a function doesn't need to know what language the function is implemented in. The main property of fungw is simplicity. The only API between objects is the plain old function call mechanism.
