Fusion is a programming language designed for writing reusable library components in a single codebase that transpiles to C, C++, C#, D, Java, JavaScript, Python, Swift, TypeScript, and OpenCL C. The compiler, written in C++, generates lightweight, human-readable code that follows each target language's conventions with no runtime dependencies.

Use cases

• write a library once and compile it to multiple languages
• transpile a single codebase to C, C++, Java, Python, and JavaScript
• share reusable components across different programming languages
• generate idiomatic code for each target language from one source
• compile Fusion code to OpenCL C for GPU kernels
• avoid maintaining parallel implementations of the same library in many languages

When to choose

• you maintain a library that must be available in many languages
• you want a single source of truth for cross-language components
• you need dependency-free, human-readable generated code
• you want to target OpenCL C for GPU computing from one codebase

When to avoid

• you need a language with a large ecosystem and community
• your project targets only one language
• you need runtime features like garbage collection or a VM
• you require extensive third-party package support
