Additionally Manuskript can help in many more ways with a spell checker, markdown highlighter, frequency analyzer, and automatic save in plain text file format.

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.

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.

A Kakoune / Neovim inspired editor, written in Rust.

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.

GNU TeXmacs is a text editing platform which is specialized for scientists. It is ideal for editing structured documents with different types of content. It has robust support for mathematical formulas and plots. It can also act as an interface to external mathematical programs such as R and Octave. TeXmacs is completely extensible via Guile.

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.

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

This package provides converters for various bibliography formats (e.g. Bibtex, RIS, etc.) using a common XML intermediate.

utf-8-lineseparator provides a tool to efficiently check text files for valid UTF-8 use and to report which line endings they use.

Enca (Extremely Naive Charset Analyser) consists of libenca, an encoding detection library, and enca, a command line frontend, integrating libenca and several charset conversion libraries and tools.

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.

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.

C library for creating and parsing configuration files.

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.

• Indicating hyperlinked text along with the hyperlink (configurable).

• Handling (bullet, decimal, letter, roman) lists along with (attempt at) indentation.

pfff is a tool for calculating a compact digital fingerprint of a file by sampling randomly from the file instead of reading it in full. Consequently, the computation has a flat performance characteristic, correlated with data variation rather than file size. pfff can be as reliable as existing hashing techniques, with provably negligible risk of collisions.

Libconfig is a simple library for manipulating structured configuration files. This file format is more compact and more readable than XML. And unlike XML, it is type-aware, so it is not necessary to do string parsing in application code.

This package implements the functionality to generate text, XML, JSON, and HTML output using a common set of function calls. The caller decides at run time which output style should be produced. Afterwards, the caller calls the function xo_emit to produce output in a format described using a format string.

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

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).

ack is a tool for finding text inside files. It is designed for hackers and programmers by being fast, ignoring VCS directories, letting a user easily specify file types, match highlighting, Perl-Compatible Regular Expressions, and being faster to type than grep.
