Wrapperit

Wrapperit is a software tool designed to generate and manage language bindings and API wrappers. It automates the creation of wrapper code that enables a program to call functions across process or language boundaries, such as calling a C library from Python or exposing a Python API to another language. The goal is to reduce boilerplate and improve consistency in cross-language interoperability.

The term wrapperit appears in developer discussions and documentation for modular binding frameworks, though there is no single canonical specification. Its usage generally centers on code generation and template-based wrapping.

Key features include a template engine for wrapper code in multiple target languages, automatic type mapping and marshalling rules, support for error translation, and incremental regeneration. It often supports plug-in backends for languages and frameworks and can integrate with build systems.

In typical workflows, a developer defines an interface description in a neutral format, configures wrapper rules, and runs the wrapperit generator to produce wrapper sources. The generated code is then compiled and consumed by the host application or library.

Advantages include reduced boilerplate, consistent error handling, and easier maintenance of bindings across releases. It can also simplify testing of cross-language interactions by isolating wrapper concerns.

Limitations include potential performance overhead, incomplete coverage of complex data types, and the need to maintain generator rules as target languages evolve. Users should evaluate security implications when wrapping untrusted components.
