Spacemacs

Spacemacs is a community-driven distribution of the Emacs text editor that combines Vim-inspired editing with Emacs’ extensibility. It aims to provide a cohesive, ready-to-use environment through a modular configuration and a curated set of packages, appealing to users who prefer Vim-style navigation and keybindings within Emacs.

A core concept in Spacemacs is the layer. Layers group related packages, settings, and conventions by language, framework, or task, enabling a scalable way to configure Emacs for different workflows. The central configuration is stored in a file named ~/.spacemacs, which contains sections for general options, a list of enabled layers, and user-specific customizations in dotspacemacs/user-config. Users declare layers in dotspacemacs/layers, and can adjust the editing style to vim, emacs, or hybrid through dotspacemacs-editing-style. The leader key, typically SPC, provides a consistent entry point for commands across modes.

Spacemacs integrates a wide range of packages for navigation, completion, project management, syntax checking, version control, and language tooling. It ships with preconfigured defaults to support common programming languages and tools, while remaining highly customizable. The distribution relies on Emacs’ package ecosystem (notably MELPA) and offers a curated experience through its layers and documentation.

Installation is usually accomplished by cloning the Spacemacs repository and running an installer that creates the initial ~/.spacemacs file and bootstraps the configuration. After setup, users can tailor layers, fine-tune options, and add personal settings. Spacemacs remains popular among users seeking Vim-like editing within Emacs, supported by a large community and extensive documentation.
