Emacs has very good support for multiple fonts in a single file. Poet uses this support to make it much more convenient to write prose within Emacs, with particular attention paid to org-mode and markdown-mode. Code blocks, tables, etc are formatted in monospace text with the appropriate backgrounds.

This Emacs library provides a Helm interface for Projectile.

This package provides an orderless completion style that divides the pattern into space-separated components, and matches candidates that match all of the components in any order. Each component can match in any one of several ways: literally, as a regexp, as an initialism, in the flex style, or as multiple word prefixes.

This package implements the tamil99 input method for Emacs. Tamil99 is a keyboard layout and input method that is specifically designed for the Tamil language. Vowels and vowel modifiers are input with your left hand, and consonants are input with your right hand.

ws-butler automatically trims trailing whitespace characters on save. In contrast with other whitespace cleanup solutions, only modified lines are trimmed.

This is a C# editing mode for Emacs, based on CC mode. It handles syntax coloring, indentation, insertion of matched pairs of curly braces and documentation generation. In addition, it provides menu-based navigation using Imenu, and Compilation mode support for MSBuild, devenv and xbuild.

This library provides easy project management and navigation. The concept of a project is pretty basic: just a folder containing special file. Currently Git, Mercurial and Bazaar repositories are considered projects by default. If you want to mark a folder manually as a project just create an empty .projectile file in it.

This package provides an ESS-like binding to send lines or regions to a REPL from Prolog buffers.

Vertico provides a minimalistic vertical completion UI, which is based on Emacs' default completion system. By reusing the default system, it achieves full compatibility with built-in Emacs commands and completion tables. Vertico is pretty bare-bone and only provides a minimal set of commands. Additional optional enhancements can be provided externally by complementary packages.

This package injects example uses of Elisp functions into their respective *Help* buffers.

This package provides custom text objects and bindings for markdown-mode.

This package provides an ESS-like binding to send lines or regions to a REPL from Scheme buffers.

This package provides a testeable Emacs Lisp API that wraps GNU Global calls and integration to editor using this API with project.el and xref.el.

GNU Hyperbole, or just Hyperbole, is a programmable hypertextual information management system. It offers rapid views and interlinking of all kinds of textual information, utilizing Emacs for editing. In particular, Hyperbole lets you quickly create and activate hyperlink buttons, build outlines, manage all your contacts, your windows and frames, and search across buffers, directory trees, or the web.

Casual is a collection of opinionated Transient-based keyboard driven user interfaces for various built-in modes.

This is an Emacs major mode for Meson build system files. Syntax highlighting works reliably. Indentation works too, but there are probably cases where it breaks.

FLIM is a library to provide basic features about message representation or encoding. FLIM-LB is a variant of FLIM, which features supports to latest Emacs.

This package provides commands for interacting with a dictionary server (as defined by RFC 2229; by default, the public server at dict.org) from within Emacs.

emacs-spark is a sparkline generation library for Emacs Lisp. It generates a sparkline string given a list of numbers. It is a port of cl-spark to Emacs Lisp.

This is an Emacs mode to give you a UI for managing init system daemons (services) for those getting tired of typing out sudo service my_thing reload all the time. It offers a consistent UI over different init systems.

This package provides a set of Emacs functions to search definitions of identifiers in the MIT-Scheme documentation.

This program was inspired by the behavior of the ``mouse documentation window'' on many Lisp Machine systems; as you type a function's symbol name as part of a sexp, it will print the argument list for that function. Behavior is not identical; for example, you need not actually type the function name, you need only move point around in a sexp that calls it. Also, if point is over a documented variable, it will print the one-line documentation for that variable instead, to remind you of that variable's meaning.

This package provides a major mode for editing OCaml code in Emacs. Some of its major features include:

• syntax highlighting (font lock);

• automatic indentation;

• querying the type of expressions (using compiler generated annot files);

• running an OCaml REPL within Emacs;

• scanning of declarations and placing them in a menu.

This package provides comint autosuggestions for Emacs eshell.
