Mozc
Mozc - a Japanese Input Method Editor designed for multi-platform
Mozc is an open source Japanese Input Method Editor (IME) developed by Google, designed to provide Japanese text input across multiple operating systems including Android, macOS, Windows, GNU/Linux, and Chromium OS. The project originated as a subset of Google Japanese Input, released publicly under the BSD 3-Clause license for community use and development. Mozc offers core IME functionality such as text conversion, prediction, and dictionary-based input, enabling users to efficiently type and edit Japanese text. While Mozc shares much of its codebase with Google’s internal IME, it operates as an independent open source project without official support, guarantees, or stable release cycles. Developers can build Mozc from source for their preferred platform, and the repository includes detailed build instructions for Android, Linux, macOS, and Windows environments. -

CIDER
The Clojure Interactive Development Environment that Rocks for Emacs
CIDER extends Emacs with support for interactive programming in Clojure. The features are centered around cider-mode, an Emacs minor-mode that complements clojure-mode. While clojure-mode supports editing Clojure source files, cider-mode adds support for interacting with a running Clojure process for compilation, debugging, definition and documentation lookup, running tests, and so on. CIDER aims to provide an interactive development experience similar to the one you’d get when programming in Emacs Lisp, Common Lisp (with SLIME or Sly), Scheme (with Geiser), and Smalltalk. Programmers are expected to program in a very dynamic and incremental manner, constantly re-evaluating existing Clojure definitions and adding new ones to their running applications. You never stop/start a Clojure application while using CIDER - you’re constantly interacting with it and changing it. -

Google Style Guides
Style guides for Google-originated open source projects
Google Styleguide is a comprehensive collection of coding style guides created and maintained by Google to ensure consistency, readability, and maintainability across its vast array of software projects. These guides define best practices and conventions for writing code in multiple programming languages, from C++ and Python to JavaScript, Go, and Swift. By adhering to these standards, developers can more easily collaborate, review code, and maintain high-quality software across teams and open source contributions. Each guide covers a wide range of topics, including naming conventions, file organization, indentation, documentation, and usage of specific language features. The repository also provides supplementary resources such as an Emacs configuration file for Google’s C++ style and references to related guidelines like Effective Dart and Kotlin Style Guide. -

Lux
The Lux Programming Language
Lux is a new programming language in the making. It's meant to be a functional, statically-typed Lisp that will run on several platforms, such as the Java Virtual Machine and JavaScript, Python, Lua, or Ruby interpreters. Lux is in the beta stage. The JVM compiler is pretty stable and the standard library has grown to a respectable size. Also, new experimental support for JavaScript, Python, Lua, and Ruby has been added. Read carefully before using this project, as the license disallows commercial use, and has other conditions which may be undesirable for some. The language is mostly inspired by the following 3 languages. Clojure (syntax, overall look & feel), Haskell (functional programming), and Standard ML (module system). They are implemented as plain-old data-structures whose expressions get eval'ed by the compiler and integrated into the type-checker. The main difference between Lux & Standard ML is that Standard ML separates interfaces/signatures and implementations/structures. -

SLIME
The Superior Lisp Interaction Mode for Emacs
SLIME is a Emacs mode for Common Lisp development. Inspired by existing systems such Emacs Lisp and ILISP, we are working to create an environment for hacking Common Lisp in. SLIME extends Emacs with support for interactive programming in Common Lisp. The features are centered around slime mode, an Emacs minor mode that complements the standard lisp mode. While lisp-mode supports editing Lisp source files, slime-mode adds support for interacting with a running Common Lisp process for compilation, debugging, documentation lookup, and so on. The Read-Eval-Print Loop ("top-level") is written in Emacs Lisp for tighter integration with Emacs. The REPL also has builtin "shortcut" commands similar to those of the McCLIM listener. SLIME is able to take compiler messages and annotate them directly into source buffers. -

Centaur Emacs
A Fancy and Fast Emacs Configuration
This is an Emacs distribution that aims to enhance the default Emacs experience. It alters a lot of the default settings, bundles a plethora of additional packages and adds its own core library to the mix. The final product offers an easy to use Emacs configuration for Emacs newcomers and lots of additional power for Emacs power users. It’s able to run on Windows, GNU Linux and macOS. It is compatible ONLY with GNU Emacs 26.1 and above. In general you’re advised to always run with the latest stable release, currently 28.2. Supports multiple programming languages, C/C++/Object-C/C#/Java, Python/Ruby/Perl/PHP/Shell/Powershell/Bat, JavaScript/Typescript/JSON/YAML, HTML/CSS/XML, and Golang/Swift/Rust/Dart/Elixir. -

ELisp Tree-sitter
Tree-sitter bindings for Emacs Lisp
tree-sitter is an Emacs binding for Tree-sitter, an incremental parsing system. It aims to be the foundation for a new breed of Emacs packages that understand code structurally. Faster, fine-grained code highlighting. More flexible code folding. Structural editing (like Paredit, or even better) for non-Lisp code. More informative indexing for imenu. The author of Tree-sitter articulated its merits a lot better in this Strange Loop talk. The minor mode tree-sitter-mode provides a buffer-local syntax tree, which is kept up-to-date with changes to the buffer’s text. Run M-x tree-sitter-hl-mode to replace the regex-based highlighting provided by font-lock-mode with tree-based syntax highlighting. -

GNU Emacs / N Λ N O
Emacs made simple
GNU Emacs / N Λ N O is a lightweight, minimalistic Emacs-inspired text editor configuration (or “distribution”) created by Nicolas P. Rougier that aims to provide a simpler and more streamlined experience compared to full-blown Emacs setups. It retains essential editing capabilities while stripping down much of the complexity and heavyweight features that can make traditional Emacs intimidating to newcomers. The project includes only minimal configuration and essential extensions, enabling users to start editing text comfortably without wrestling with a steep learning curve or bloated init files. This makes it appealing for users who like the power of Emacs (or similar advanced editors) but want a fast, responsive, and easy-to-maintain editor. Nano-Emacs can be especially useful for scripting, quick edits, data-analysis workflows, or writing in scientific/research contexts, especially when you want something more powerful than a simple text editor but lighter than a full IDE. -

Casual Suite
An umbrella package to support a single install point
An umbrella package to support a single installation point for all Casual user interfaces for Emacs. These user interfaces built with Transient are included via the Elisp library header Package-Requires. It is highly recommended that a deep reading of the install procedure for each user interface be done beforehand as each of them has their own recommended customizations to go alongside them. Casual Suite requires Casual Lib which in turn requires a recent installation of Transient 0.6.0+ from either ELPA or MELPA. As an older version of Transient is built-in to the Emacs release, the package manager package.el will not update this package unless the customizable variable package-install-upgrade-built-in is set to t. Set this variable and proceed with installing Casual Suite. Alternately invoking package-install with a prefix (C-u) will temporarily coerce the update of the built-in package.
