## プロジェクトの歴史と使われ方

Gravity is an embeddable, dynamically typed programming language implemented in C. It is packaged as a command-line interpreter/runtime but is historically most important as a small VM designed to be embedded in applications.

### プロジェクトの歴史

The official README says Gravity was developed from scratch for the Creo project to provide portable code across iOS and Android. It combines a class-based, concurrent scripting model with Swift-like syntax and a small native runtime.

The project site presents Gravity as a small high-performance language with no external dependencies and a VM intended to add little overhead to an application. The GitHub release series records continuing maintenance of the interpreter and runtime.

### 採用の歴史

Gravity's adoption is specialized rather than ecosystem-wide. The official README names Creo as a core embedding target and the Untold game engine as another use case.

In package-manager terms, Gravity appeals to developers who want a lightweight scripting language or a studyable bytecode VM without pulling in a large external runtime.

### 使われ方

Users can run the Gravity executable for scripts or embed the language in a C/C++ application. Its documented language model supports procedural, object-oriented, functional, data-driven, and prototype-style programming patterns.

The lack of external dependencies is part of the intended deployment story: package managers can build a small C runtime, while embedders can include the VM in an application.

### パッケージ好きにとっての重要性

Gravity is interesting to package nerds because it is a compact language runtime rather than a mainstream language ecosystem. It packages cleanly as a native executable while also serving as embeddable infrastructure.

It is also a useful comparison point with Lua, Wren, Squirrel, and other application scripting languages: the package is less about global ecosystem adoption and more about how easily a host application can carry a scripting VM.

### タイムライン

- 2013: Marco Bambini's site associates Gravity with work beginning in 2013.
- 2018: Public attention around the Gravity site and repository highlighted the embeddable VM design.
- 2020: The maintainer opened GitHub Discussions for project questions and community discussion.
- 2026: The GitHub release page records 0.9.x maintenance releases with runtime and compiler fixes.

### Related projects

- Creo: the official README describes Gravity as the core language built into Creo.
- Untold game engine: the official README names Gravity as its scripting language.
- Lua, Wren, and Squirrel are comparable embeddable scripting-language package niches, though they are separate projects.
