pygls – a Pythonic generic language server

In plain words

Pygls is a Python framework for building language servers that conform to the Language Server Protocol standard. It enables developers to create tools that provide code intelligence features like autocompletion, error checking, and documentation across different code editors. The framework abstracts away protocol complexity, allowing developers to focus on language-specific logic rather than communication details. Pygls is designed for anyone building custom language support or editor integrations in Python.

  I built a hardware processor that runs Python2025 · runpyxl.com · ▲983

  Hi everyone, I built PyXL — a hardware processor that executes a custom assembly generated from Python programs, without using a traditional interpreter or virtual machine. It compiles Python -> CPython Bytecode -> Instruction set designed for direct hardware execution. I’m sharing an early benchmark: a GPIO test where PyXL achieves a 480ns round-trip toggle — compared to 14-25 micro seconds on a MicroPython Pyboard - even though PyXL runs at a lower clock (100MHz vs. 168MHz). The design is stack-based, fully pipelined, and preserves Python's dynamic typing without static type restrictions.…

  Multilspy – Cross platform framework to develop Language Server Clients2024 · github.com · ▲38

  multilspy is a cross-platform library that we have built to set up and interact with various language servers in a unified and easy way. Language servers are tools that perform a variety of static analyses on source code and provide useful information such as type-directed code completion suggestions, symbol definition locations, symbol references, etc., over the Language Server Protocol (LSP). multilspy intends to ease the process of using language servers, by abstracting the setting up of the language servers, performing language-specific configuration and handling communication with the…

  A modular Python TUI framework with a fast and pretty markup language2022 · github.com · ▲114

  PyTermGUI is a highly modular framework offering most of the features one would expect from a GUI library, such as a mature and open Widget API, animations, mouse support and other goodies, right inside the terminal! The markup language is another great feature of the library, and is used by practically all elements of it. It is based on Rich's implementation, but uses a more concise and easier to humanly parse syntax, while being over 10 times faster at parsing due to a long list of optimizations. There is a full Window Manager API included as well, allowing the user to move, resize and…

  Multilspy – Cross platform framework to develop Language Server Clients2024 · github.com · ▲10

  multilspy is a cross-platform library designed to simplify the process of creating language server clients to query and obtain results of various static analyses from a wide variety of language servers that communicate over the Language Server Protocol. It is easily extensible to support any language that has a Language Server and currently supports Java, Rust, C# and Python. We aim to continuously add support for more language servers and languages. Language servers are tools that perform a variety of static analyses on code repositories and provide useful information such as type-directed…

  Talanoa▲341

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
