Helix is a modal text editor built in Rust for the terminal. It uses multiple selections as a core editing primitive and integrates Tree-sitter for syntax highlighting, indent calculation and code navigation. Language server support provides completion, goto definition, documentation and diagnostics. Built-in features include a fuzzy finder, project-wide search and themes. A plugin system and GUI frontend are planned but not currently available.
CP Editor is an IDE for competitive programmers that automates compilation, execution and testing. It fetches sample test cases from competitive programming platforms and can submit solutions to Codeforces, with support for C/C++, Java and Python.
RTutor is a website and open-source project for analyzing data; users upload data, ask questions, and receive results in seconds. The site states that the RTutor website and source code are free for non-profit organizations only, with licensing required for commercial use. It also notes an 8-minute YouTube video for first-time users.
NvChad is a Neovim configuration that provides defaults and a UI, written in Lua and managed with lazy.nvim. It includes its own UI plugins, such as the base46 theming plugin with 68 themes, plus statusline, tabufline, terminal and dashboard modules. Its documentation lists prerequisites including Neovim 0.11 and a Nerd Font.
An open-source online code playground for running code in dozens of programming languages. Users can create, execute, save and share snippets, and the editor supports Vim and Emacs key bindings. Code runs in a temporary container with network access disabled. Snippets can be saved as public, unlisted or secret.
Prettier is an opinionated code formatter that supports many languages, including JavaScript, TypeScript, CSS, HTML, JSON, GraphQL, Markdown and YAML. It reprints code from scratch, taking line length into account, to enforce a consistent style across a codebase. Prettier integrates with most editors.
Meld is a visual diff and merge tool for comparing files, directories, and version-controlled projects. It provides two- and three-way comparison, three-way merge assistance with conflict handling, and support for Git, Mercurial, Bazaar, and Subversion. It is packaged for Linux/Unix distributions and Flathub, with a Windows installer available; macOS support is not yet official.
