The Howdy Glossary

Flow is a programming language conceived to simplify the development process by synthesizing Java code, enabling developers to build programs without directly writing code. It includes core features such as a type system with polymorphism, type inference, and reification, alongside support for higher-order functions and concurrent programming via the actor model. These features automate workflow validation and error-checking before runtime, which helps prevent issues during execution and streamlines development.

Developed by researchers from Purdue University's Programming Systems Lab under Professor Tiark Rompf's guidance, Flow aims to reduce manual coding efforts while minimizing errors. Its design addresses various aspects of software creation by offering a robust type system for flexibility and clarity in coding. Flow’s higher-order functions aid in modularizing logic, while its concurrency support via the actor model enhances scalable application development.

Compared to languages like Kotlin, Swift, and Rust that also aim to simplify programming and enhance safety features, Flow distinguishes itself through its unique emphasis on automating error-checking processes and synthesizing Java code directly from structured inputs. This automation allows developers to focus more on program logic rather than syntax or debugging errors pre-runtime. With these innovative approaches combined with support for concurrent programming models and sophisticated typing mechanisms, Flow positions itself as a potent tool for enhancing productivity and reducing complexity in software development workflows.
