rust.vim
Vim configuration for Rust
rust.vim is the official Vim plugin from the Rust Lang Foundation team that adds support for Rust files in Vim and Neovim. It provides file-detection (so .rs files are recognised), syntax highlighting tuned for Rust’s syntax and macros, and supports formatting via rustfmt and other language-specific tooling. The plugin also integrates with other Vim tools and linters, helping you build a full Rust-editing workflow in Vim. Because Rust’s macro system and language features are more complex than many languages, rust.vim handles special tokens and highlights accordingly. Though it doesn’t itself provide full language-server (LSP) capabilities, it lays the foundation so you can plug in LSP or other completion/diagnostic plugins. Many Rust users say that rust.vim is a reliable baseline for making Vim feel like a competent Rust editor rather than a bare text editor. -

QPyDesk
Code editor and real-time QR code generator for QPython
QPyDesk is a code editor, and real-time QR code generator for QPython. It is a Python code editor with syntax highlighting that also generates the QR code that represents said code in real time. This application also allows you to print the generated QR code to distribute the created application. However, because QR codes have a limited storage capacity, if the code is very long, QPyDesk creates a QR code that is only valid while the application is running, that is, the QR code generated in this case is useless for distribute the application, but it is still useful to check the operation of the script while it is encoded from the computer. When these circumstances occur, QPyDesk notifies the user and disables the print button. QPyDesk gives dynamism during the development of applications for QPython / Android, since it takes advantage of the QPython QR code reader to work comfortably from the computer for the android device. -

CoVim
Collaborative Editing for Vim
CoVim enables collaborative, real-time editing sessions in Vim by networking multiple clients into a shared buffer. Participants can see each other’s cursors and changes as they type, approximating pair programming inside a modal editor. Sessions are hosted on a server process that coordinates edits and user presence across machines. The goal is to keep collaboration simple while preserving familiar Vim motions and commands. It is particularly handy for remote code walkthroughs, mentoring, or quick review sessions without switching to a different editor. While not as full-featured as cloud IDEs, it provides a lightweight way to co-edit in pure Vim. -

EditorConfig
Sublime Text plugin for EditorConfig
EditorConfig Sublime is a Sublime Text plugin that applies EditorConfig coding-style rules to files opened in the editor. It helps teams maintain consistent formatting conventions even when developers use different editors or operating systems. Supported settings include indentation style and size, line endings, character encoding, trailing-whitespace removal, and final-newline insertion. The plugin reads these preferences from standard .editorconfig files associated with a project. It can be installed through Sublime Text's Package Control system and includes syntax support for EditorConfig files. A bundled snippet helps users create configuration files without memorizing every property. Developers can also inspect the currently active configuration through the Sublime console. -

OpenAI Sublime Text Plugin
First class Sublime Text AI assistant with gpt-5, Opus 4.6, Gemini 3
OpenAI Sublime Text is a full-featured AI assistant plugin designed to bring advanced language model capabilities into the Sublime Text editor with a deeply integrated user experience. It supports a wide range of providers, including OpenAI, Anthropic, Google Gemini, and local backends like Ollama or llama.cpp, making it highly flexible for different deployment scenarios. The plugin offers both chat-based interaction and inline assistance through “phantoms,” which display non-intrusive responses directly within the editor view. It allows users to send selected code, entire files, or diagnostic outputs as context, enabling more precise and relevant responses. The system includes project-specific chat histories and assistant configurations, helping users maintain context across different development tasks. It also supports streaming responses, proxy configuration, and detailed status indicators such as token usage and active model information. -

PhPyCli
Edit and execute php code
PhPyCli is an app for write and execute php code (other language available). I decided to make it because i thought it could be interesting to play with php through a GUI rather than through a terminal. The work I've made, is one of somebody who has learnt python by itself. I'm not an engineer This work it's just an attempt to realise my app project. Please be indulgent! All the work is yet to be done, what I present is just the begining. And if you like it, please improve it, evolve it. Thanks! :) PhPyCli has been written under Fedora Linux, in Python and with the wxPython GUI toolkit. -

Vimplus
An automatic configuration program for vim
vimplus is an opinionated Vim “distribution” and automatic configuration program by chxuan which bundles a large number of plugins and configurations so that you can essentially install Vim once and have a fully-loaded development setup. Rather than starting with a bare .vimrc and gradually adding plugins, vimplus gives you a pre-configured environment that includes file explorers, completion, status lines, themes, and more. It includes a custom installer and update script, and places a lot of the configuration into ~/.vimrc.custom.plugins and ~/.vimrc.custom.config for user customisations. This approach can save a lot of time for users who don’t want to spend weeks assembling their Vim environment. However, because it includes many plugins and opinionated mappings, some users feel it’s heavier than a minimal Vim setup and may require unlearning some defaults. For developers who want a “just work” Vim setup for C/C++, Python, JavaScript, etc., vimplus is a very strong starting point.
