Open Source Emacs-Lisp Text Editors for Linux

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.

This repository contains the official collection of snippets for yasnippet. You can install this package from melpa, by first ensuring that you have the melpa source in your package-archives. Snippets need to be generic enough to be useful for everyone, and not contain anything specific to your own system. Until September 1st 2014 there were a lot of HTML snippets in the repository, which sometimes were useful, but I came to the conclusion that yasnippet was not the right tool for them, so they were removed. YASnippet is a template system for Emacs. It allows you to type an abbreviation and automatically expand it into function templates. Bundled language templates include: C, C++, C#, Perl, Python, Ruby, SQL, LaTeX, HTML, CSS and more. The snippet syntax is inspired from TextMate's syntax, you can even import most TextMate templates to YASnippet. Watch a demo on YouTube.

RefDB is a reference database and bibliography tool for SGML, XML, and LaTeX documents, sort of a Reference Manager or BibTeX for markup languages. It is portable and known to run on Linux, Free/NetBSD, OSX, Solaris, and Windows/Cygwin.

DictEm is an extremely customizable Dictionary client for (X)Emacs. It implements functions of the client part of the Dictionary protocol (RFC-2229). It widely uses autocompletion and provides powerful API that allows to heavily extend its functionality.

Easymacs is an easy-to-learn, one-size-fits-all configuration for new users of GNU Emacs.

Casi mode is a minor mode that allows you to input programs of C like languages in different styles automatically while keeping your key pressing style.

EPT (Emacs Package Tool) is full userspace package managing tool for GNU/Emacs.

Bone Yard is a simple method for inserting default, mode specific, text into empty Emacs buffers. It's used to easily load boilerplate text to get started with new programs.

The Breadcrumb package is an Emacs add-on module that allows setting a series of quick bookmarks in Emacs. The bookmarks are global across different editing buffers, leaving a trail of breadcrumbs across them that you can jump back to quickly.

CC Mode is a GNU Emacs and XEmacs mode for editing C and other languages with similar syntax; currently C++, Objective-C, Java, CORBAs IDL, Pike, and AWK. It is a standard package in both GNU Emacs and XEmacs.

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.

clojure-mode is an Emacs major mode that provides font-lock (syntax highlighting), indentation, navigation and refactoring support for the Clojure(Script) programming language. MELPA Stable is the recommended repo as it has the latest stable version. MELPA has a development snapshot for users who don't mind (infrequent) breakage but don't want to run from a git checkout. Available on the major package.el community maintained repos, MELPA Stable and MELPA repos. All the major modes derive from clojure-mode and provide more or less the same functionality. Differences can be found mostly in the font-locking - e.g. ClojureScript has some built-in constructs that are not present in Clojure. The proper major mode is selected automatically based on the extension of the file you're editing. Having separate major modes gives you the flexibility to attach different hooks to them and to alter their behavior individually (e.g. add extra font-locking just to clojurescript-mode) .

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.

Emacs Lisp libraries for GNU Emacs or XEmacs.

ESense - Erlang "IntelliSense" for Emacs

An extensible emacs startup screen showing you what’s most important. The widget “projects”, which shows a list of recent projects, is not enabled by default since it depends on packages that might not be available. To activate the widget, set the variable dashboard-projects-backend to either =’projectile= (projectile, available from melpa) or =’project-el= (project.el, available from GNU elpa), then add an entry like (projects . 5) to the variable dashboard-items. The agenda is now sorted with dashboard-agenda-sort-strategy following the idea of org-agenda-sorting-strategy. Supported strategies are priority-up, priority-down, ~time-up, time-down, todo-state-up and todo-state-down.

markdown-mode is a major mode for editing Markdown-formatted text. The latest stable version is markdown-mode 2.5, released on Feb 12, 2022. See the release notes for details. markdown-mode is free software, licensed under the GNU GPL, version 3 or later. The primary documentation for Markdown Mode is available below, and is generated from comments in the source code. For a more in-depth treatment, the Guide to Markdown Mode for Emacs covers Markdown syntax, advanced movement and editing in Emacs, extensions, configuration examples, tips and tricks, and a survey of other packages that work with Markdown Mode. Finally, Emacs is also a self-documenting editor. This means that the source code itself contains additional documentation: each function has its own docstring available via C-h f (describe-function), individual keybindings can be investigated with C-h k (describe-key), and a complete list of keybindings is available using C-h m (describe-mode).

Emacs mode for the programming language Maude.

Link multiple files together in Emacs.

This project provides a tiny .emacs file to set up Emacs quickly. This document provides a detailed description of how to set it up and get started with Emacs. Further this project also provides a tiny convenience command named em to start Emacs server and edit files using Emacs server. This helps in using Emacs efficiently. This script and its usage is explained in detail later in the Emacs Server and Emacs Launcher sections. If you are already comfortable with Emacs and only want to understand the content of .emacs or em, you can skip ahead directly to the Line-by-Line Explanation section that describes every line of these files in detail. The .emacs file in this project provides a quick way to get started with setting up your Emacs environment. This document explains how to do so in a step-by-step manner. This document also explains the content of .emacs and em in a line-by-line manner.

Emacs incremental completion and selection narrowing framework. Helm is an Emacs framework for incremental completions and narrowing selections. It helps to rapidly complete file names, buffer names, or any other Emacs interactions requiring selecting an item from a list of possible choices. Helm is a fork of anything.el, which was originally written by Tamas Patrovic and can be considered to be its successor. Helm cleans the legacy code that is leaner, modular, and unchained from constraints of backward compatibility. Helm is an Emacs framework for incremental completions and narrowing selections.

A Cocoa port of GNU Emacs for GNUstep and MacOS X.

This is a collection of Evil bindings for the parts of Emacs that Evil does not cover properly by default, such as help-mode, M-x calendar, Eshell and more. Reduce context switching: As soon as “moving around” gets hardwired to <hjkl>, it becomes frustratingly inefficient not to have it everywhere. Community work: setting up bindings is tremendous work and joining force can only save hours for all of Evil users out there. While not everyone may agree on the chosen bindings, it helps to have something to start with rather than nothing at all. In the end, users are free to override a subset of the proposed bindings to best fit their needs. Having all bindings defined in one place allows for enforcing consistency across special modes and coordinating the community work to define a reference implementation.

Flycheck is a modern on-the-fly syntax-checking extension for GNU Emacs, intended as replacement for the older Flymake extension which is part of GNU Emacs. For a detailed comparison to Flymake see Flycheck versus Flymake. It uses various syntax checking and linting tools to automatically check the contents of buffers while you type, and reports warnings and errors directly in the buffer, or in an optional error list. Out of the box Flycheck supports over 40 different programming languages with more than 80 different syntax-checking tools, and comes with a simple interface to define new syntax checkers. Many 3rd party extensions provide new syntax checkers and other features like alternative error displays or mode line indicators. Flycheck needs GNU Emacs 24.3+, and works best on Unix systems. Windows users, please be aware that Flycheck does not support Windows officially, although it should mostly work fine on Windows.
