Scintilla is a source code editing component for GTK+. It has the usual features found in text editing components, as well as some that are especially useful for editing and debugging source code; these include support for syntax styling, error indicators, code completion and call tips. Styling choices are more open than with many editors: Scintilla lets you use proportional fonts, bold and italics, multiple foreground and background colours, and multiple fonts.

QEmacs (for Quick Emacs) is a very small but powerful editor. It has features that even big editors lack:

• Full screen editor with an Emacs look and feel with all Emacs common features: multi-buffer, multi-window, command mode, universal argument, keyboard macros, config file with C-like syntax, minibuffer with completion and history.

• Can edit files of hundreds of Megabytes without being slow by using a highly optimized internal representation and by mmaping the file.

• Full Unicode support, including multi charset handling (8859-x, UTF8, SJIS, EUC-JP, ...) and bidirectional editing respecting the Unicode bidi algorithm. Arabic and Indic scripts handling (in progress).

• WYSIWYG HTML/XML/CSS2 mode graphical editing. Also supports Lynx like rendering on VT100 terminals.

• WYSIWYG DocBook mode based on XML/CSS2 renderer.

• C mode: coloring with immediate update. Emacs like auto-indent.

• Shell mode: colorized VT100 emulation so that your shell work exactly as you expect. Compile mode with next/prev error.

• Input methods for most languages, including Chinese (input methods come from the Yudit editor).

• Hexadecimal editing mode with insertion and block commands. Unicode hexa editing is also supported.

• Works on any VT100 terminals without termcap. UTF8 VT100 support included with double width glyphs.

• X11 support. Support multiple proportional fonts at the same time (as XEmacs). X Input methods supported. Xft extension supported for anti aliased font display.

• Small! Full version (including HTML/XML/CSS2/DocBook rendering and all charsets): 200KB big. Basic version (without bidir/unicode scripts/input/X11/C/Shell/HTML/Dired): 49KB.

Jed is a powerful programmer's editor using the S-Lang scripting language for configuration and extensibility. It provides emulation modes for the key bindings of many editors (including Emacs and WordStar), and has syntax highlighting for dozens of languages. Jed is very small and fast.

Leafpad is a GTK+ text editor that emphasizes simplicity. As development focuses on keeping weight down to a minimum, only the most essential features are implemented in the editor. Leafpad is simple to use, is easily compiled, requires few libraries, and starts up quickly.

Vis aims to be a modern, legacy free, simple yet efficient vim-like text editor. It extends vim's modal editing with built-in support for multiple cursors/selections and combines it with sam's structural regular expression based command language.

Lexilla is a library of language lexers that can be used with the Scintilla editing component.

Hexer is a multi-buffer editor for binary files for Unix-like systems that displays its buffer(s) as a hex dump. The user interface is kept similar to vi/ex.

A soft fork of Helix which introduces keybindings and other features to make it more comfortable for Vim users. Changes include:

• Vim keybindings

• Adjusted behaviours and defaults for Visual line mode

• Basic Vim modeline support

• Support for colored/rainbow indentation guides

• Minimalistic window separator

Moreover, evil-helix introduces the editor.evil option, which is true by default. It can be set to false to completely deactivate evil-helix behavior without having to use a different build.

Rassumfrassum is a LSP/JSONRPC multiplexer that allows one LSP client (Emacs' eglot, Neovim, etc.) to connect to multiple language servers seamlessly.

Mogan is a scientific structural text editor, a fork of GNU TeXmacs.

parinfer-rust-emacs is an Emacs-centric fork of parinfer-rust, itself an implementation of Shaun Lebron’s Parinfer. This builds a shared library intended to be loaded by the emacs-parinfer-rust-mode Emacs plugin, though a standalone binary is built also.

Mg (mg) is a GNU Emacs style editor, with which it is "broadly" compatible. This is a portable version of the mg maintained by the OpenBSD team.

dte is a portable console text editor with features like multiple buffers/tabs, syntax highlighting, customizable color scheme (including support for 24-bit true colours), kitty keyboard protocol, editorconfig support, amongst other features.

Vi is the original screen based text editor for Unix systems. It is considered the standard text editor, and is available on almost all Unix systems. Nvi is intended as a "bug-for-bug compatible" clone of the original BSD vi editor. As such, it doesn't have a lot of snazzy features as do some of the other vi clones such as elvis and vim. However, if all you want is vi, this is the one to get.

mle is a small, flexible, terminal-based text editor written in C. Notable features include: full Unicode support, syntax highlighting, scriptable rc file, macros, search and replace (PCRE), window splitting, multiple cursors, and integration with various shell commands.

micro is a terminal-based text editor that aims to be easy to use and intuitive, while also taking advantage of the capabilities of modern terminals.

Kakoune is a code editor heavily inspired by Vim, as such most of its commands are similar to Vi's ones, and it shares Vi's "keystrokes as a text editing language" model. Kakoune has a strong focus on interactivity, most commands provide immediate and incremental results, while still being competitive (as in keystroke count) with Vim.

libconfuse is a configuration file parser library. It supports sections and (lists of) values (strings, integers, floats, booleans or other sections), as well as some other features (such as single/double-quoted strings, environment variable expansion, functions and nested include statements).

This package provides the tldr command allowing users to view tldr pages from a shell. The tldr pages are a community effort to simplify the man pages with practical examples described in https://tldr.sh/.
