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. -

telega.el
GNU Emacs telegram client (unofficial)
telega is a full-featured unofficial client for Telegram platform for GNU Emacs. telega is actively developed, for this reason, some features are not implemented, or they are present just as skeletons for future implementation. However, the core parts are mature enough so that it is possible to use telega on daily basis. telega depends on the visual-fill-column and rainbow-identifiers packages. This dependency automatically installs if you install telega from MELPA or GNU Guix. Otherwise, will you need to install these packages by hand? telega is built on top of the official library provided by Telegram TDLib. Most distributions do not provide this package in their repositories, in which case you will have to install it manually by following the instructions. GNU Guix, however, does have both telega and TDLib packaged. If you use GNU Guix you can skip directly to Installing from GNU Guix. -

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. -

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. -

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. -

Tomorrow Theme
Tomorrow Theme
Tomorrow Theme is a family of carefully balanced color schemes designed to provide consistent, readable syntax highlighting across editors, terminals, and code-hosting sites. The palette comes in multiple variants—Tomorrow (light) and several “Tomorrow Night” options like Bright, Blue, and Eighties—so developers can choose a tone that matches their environment without losing legibility. Each scheme defines a small, harmonious set of base and accent colors that map predictably to tokens such as keywords, strings, numbers, and comments, reducing visual noise while preserving structure. The project ships ports for a wide range of tools (from Vim and Emacs to Sublime Text, iTerm, and more) and documents the palette so others can create faithful ports. Its emphasis on restraint and consistency makes it a popular baseline for teams that want code to look familiar across machines and applications. -

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. -

Magit
A Git porcelain inside Emacs
Magit is a complete text-based user interface to Git. It fills the glaring gap between the Git command-line interface and various GUIs, letting you perform trivial as well as elaborate version control tasks with just a couple of mnemonic key presses. Magit looks like a prettified version of what you get after running a few Git commands but in Magit every bit of visible information is also actionable to an extent that goes far beyond what any Git GUI provides and it takes care of automatically refreshing this output when it becomes outdated. In the background Magit just runs Git commands and if you wish you can see what exactly is being run, making it possible for you to learn the git command-line by using Magit. Using Magit for a while will make you a more effective version control user. Magit supports and streamlines the use of Git features that most users and developers of other Git clients apparently thought could not be reasonably mapped to a non-command-line interface. -

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. -

Smartparens
Minor mode for Emacs that deals with parens pairs
Smartparens is a minor mode for dealing with pairs in Emacs. We generally target GNU Emacs version 24.3 and newer, however, everything should work mostly fine on anything newer than version 24. You can install smartparens from MELPA. Once installed, enable the default configuration. You may want to try smartparens-strict-mode. This enforces that pairs are always balanced, so commands like kill-line keep your code well-formed. Inside Emacs, M-x sp-cheat-sheet will show you all the commands available, with examples. Smartparens has a default configuration that works well for most languages. For language-specific behaviour, smartparens has a separate smartparens-FOO.el file for every language and smartparens-config.el loads these automatically. -
