The introduction of Borgo, a statically typed language that transpiles to Go, reignited a classic debate within the programming community about the definitions and distinctions between a ‘compiler’ and a ‘transpiler’. Designed in Rust, Borgo presents itself as a bridge for developers seeking the simplicity of Go with enhanced type safety, leveraging the robustness of Rust. This blend has sparked discussions not just about language capabilities but also about language processing terminology.
Interestingly, the terminological debate is seen in the project’s own documentation. Some parts declare that Borgo ‘compiles’ to Go, while others specify that it ‘transpiles’. This discrepancy might not just be an oversight or marketing jargon as suggested by some community members; it reflects a deeper lack of consensus on what exactly distinguishes a compiler from a transpiler. The traditional view suggests that compilers translate from a high-level programming language to machine code, while transpilers translate from one programming language to another.
This distinction, however, does not hold much water anymore, as seen in the variety of opinions from the programming community. Some argue that since all these processes involve translating code, the difference is more about the output format rather than the process itself. Whether the output is machine code or another high-level language’s code, the fundamental operations of parsing, interpreting, and optimizing code remain consistent across both compilers and transpilers.
Within this context, Borgo’s choice of Rust as a development tool while targeting Go as a compilation target is fascinating. Rust offers robust memory safety features and concurrency management, while Go is known for its simplicity and high-performance networking capabilities. By transpiling to Go, Borgo attempts to bring enhanced type safety and features from Rust into Go’s ecosystem, making it an attractive proposition for Go developers seeking more sophisticated language constructs without departing from the Go ecosystem.
The practical implications for developers are significant. Using Borgo, developers can potentially write safer and more reliable Go code. For instance, transitioning from using multiple third-party dependencies for type safety in Go to using Borgo can reduce the cognitive load on developers by simplifying error handling and data manipulation with robust type systems and enum support borrowed from Rust.
However, this blending of language features through transpilation also brings challenges. The output code must remain idiomatic to the target language to ensure compatibility and maintainability. If the transpiled code strays too far from idiomatic Go, it could lead to maintenance challenges, especially in larger teams or community-driven projects. This concern ties back into the broader discussion on the role of transpilers in programming: while they enable language evolution and experimentation, they must also align closely with the target language’s standards and practices.
This discussion also underscores a broader philosophical question about the evolution of programming languages: Is the future of programming languages about creating entirely new languages, or is it about evolving existing languages through tools like transpilers that merge the best features of multiple languages? Borgo represents an interesting case study in this regard, as it strives to balance between innovation and practicality, pushing the boundaries of what’s possible in Go while drawing from the strengths of Rust.
Conclusively, while Borgo sparks debate about compilers versus transpilers, it also symbolizes the ongoing evolution and hybridization in programming languages. Whether one prefers to call Borgo’s process ‘compiling’ or ‘transpiling’ might be less important than recognizing its potential impact on the way we write, think about, and categorize programming languages. As programming language theory and practice evolves, perhaps these terms will merge or new terminology will arise, reflecting a field that is always in flux and driven by a quest for better tools and more expressive ways to instruct our machines.
