The Expression Problem and its solutions

news.ycombinator.com Unknown 2025-10-09 08:28:04

The craft of programming is almost universally concerned with different types of data and operations/algorithms that act on this data . Therefore, it's hardly surprising that designing abstractions for data types and operations has been on the mind of software engineers and programming-language designers since... forever. Yet I've only recently encountered a name for a software design problem which I ran into multiple times in my career. It's a problem so fundamental that I was quite surprised

Improvements to OCaml code editing: the basics of a refactor engine

news.ycombinator.com Unknown 2025-11-08 08:37:15

Refactoring features have contributed to the popularity of editors like IntelliJ, as well as certain programming languages whose editor support offers interactive mechanisms to manage code — Gleam being an excellent example. Even though OCaml has some features related to refactoring (such as renaming occurrences, substituting typed holes with expressions, and case analysis for pattern matching), the goal of my internship was to kickstart work on a robust set of features to enable the smooth inte

NativeJIT: A C++ expression –> x64 JIT (2018)

news.ycombinator.com Unknown 2026-02-16 14:59:52

NativeJIT NativeJIT is an open-source cross-platform library for high-performance just-in-time compilation of expressions involving C data structures. The compiler is light weight and fast and it takes no dependencies beyond the standard C++ runtime. It runs on Linux, OSX, and Windows. The generated code is optimized with particular attention paid to register allocation. The compiler was developed by the Bing team for use in the Bing search engine. One important use is scoring documents contai
