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.

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.

GNU Moe is a powerful-but-simple-to-use text editor. It works in a modeless manner, and features an intuitive set of key-bindings that assign a degree of severity to each key; for example, key combinations with the Alt key are for harmless commands like cursor movements while combinations with the Control key are for commands that will modify the text. Moe features multiple windows, unlimited undo/redo, unlimited line length, global search and replace, and more.

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

JOE is a powerful console screen editor with a "mode-less" user interface similar to many user-friendly editors. JOE has some of the key bindings and many of the powerful features of GNU Emacs.

AutoComplete is a library allowing you to add IDE-like auto-completion (aka "code completion" or "Intellisense") to any Swing JTextComponent. Special integration is added for RSyntaxTextArea, since this feature is commonly needed when editing source code. Features include: Drop-down completion choice list. Optional companion "description" window, complete with full HTML support and navigable with hyperlinks. Optional parameter completion assistance for functions and methods, ala Eclipse and NetBeans. Completion information is typically specified in an XML file, but can even be dynamic.

cobib is a command-line based bibliography management tool. It uses a plain-text database, a location-independent library, and features git integration, command-line support, and a curses-based TUI.

docx2txt is a Perl based command line utility to convert Microsoft Office .docx documents to equivalent text documents. Latest version supports following features during text extraction.

• Character conversions; currency characters are converted to respective names like Euro.

• Capitalisation of text blocks.

• Center and right justification of text fitting in a line of (configurable) 80 columns.

• Horizontal ruler, line breaks, paragraphs separation, tabs.

The drm_tools package contains the following commands:

accudate

An extended version of the "date" program that has sub-second accuracy.

binformat

Format complex binary data into text.

binload

Load data into a binary file using simple commands from the input.

binorder

Sort, merge, search, retrieve or generate test data consisting of fixed size binary records.

binreplace

Find or find/replace in binary files.

binsplit

Split test data consisting of fixed size binary records into one or more output streams.

chardiff

Find changes between two files at the character level. Unlike "diff", it lists just the characters that differ, so if the 40,000th character is different only that one character will be shown, not the entire line.

columnadd

Add columns of integers, decimals, and/or times.

datasniffer

A utility for formatting binary data dumps.

dmath

Double precision interactive command line math calculator.

extract

Extract and emit data from text files based on character or token position.

execinput

A utility that reads from STDIN and executes each line as a command in a sub-process.

indexed_text

A utility for rapid retrieval of text by line numbers, in any order, from a text file.

mdump

Format binary data.

msgqueue

Create message queues and send/receive messages.

mbin

dtmbout

Multiple buffer in and out. Used for buffering a lot of data between a slow device and a fast device. Mostly for buffering streaming tape drives for use with slower network connections, so that streaming is maintained as much as possible to minimize wear on the tape device.

pockmark

Corrupt data streams - useful for testing error correction and data recovery.

tarsieve

Filter, list, or split a tar file.

The Recode library converts files between character sets and usages. It recognises or produces over 200 different character sets (or about 300 if combined with an iconv library) and transliterates files between almost any pair. When exact transliteration are not possible, it gets rid of offending characters or falls back on approximations. The recode program is a handy front-end to the library.

txt2tags is a document generator. It reads a text file with minimal markup and converts it to multiple formats.

CityHash provides hash functions for strings. The functions mix the input bits thoroughly but are not suitable for cryptography.

dos2unix is a tool to convert line breaks in a text file from Unix format to DOS format and vice versa.

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/.

RSyntaxTextArea is a syntax highlighting, code folding text component for Java Swing. It extends JTextComponent so it integrates completely with the standard javax.swing.text package. It is fast and efficient, and can be used in any application that needs to edit or view source code.
