XNEdit is a fast and classic X11 text editor, based on NEdit, with full unicode support and antialiased text rendering.

Fe is a small folding editor. It folds arbitrary text regions; it is not bound to syntactic units.

Fe has no configuration or extension language and requires no setup. Its user interface is emacs-like and it has menus for the very most important functions to help beginners. Further there is a reference card. It offers:

• Regions and Emacs-like kill ring

• Incremental search

• Keyboard macros

• Editing binary files

• Multiple windows and views

• Compose function for Latin 1 characters

aha (Ansi Html Adapter) converts ANSI escape sequences of a Unix terminal to HTML code.

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

Miller (mlr) is like awk, sed, cut, join, and sort for data formats such as CSV, TSV, JSON, JSON Lines, and positionally-indexed. It supports format conversion and pretty-printing.

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.

csvdiff is a diff tool to compute changes between two CSV files. It can compare CSV files with a million records in under 2 seconds. It is specifically suited for comparing CSV files dumped from database tables. GNU Diff is orders of magnitude faster for comparing line by line. csvdiff supports

• Selective comparison of fields in a row

• Specifying group of columns as primary-key to uniquely identify a row

• Ignoring columns

• Several output formats including colored git style output or JSON for post-processing

This package transforms JSON into discrete assignments to make it easier to use line-based tools such as grep to search for what you want and see the absolute "path" to it.

This package provides yq, a command-line YAML, JSON and XML processor. It uses jq-like syntax but works with YAML files as well as JSON, XML, properties, CSV and TSV.

Open Chinese Convert (OpenCC) converts between Traditional Chinese and Simplified Chinese, supporting character-level conversion, phrase-level conversion, variant conversion, and regional idioms among Mainland China, Taiwan, and Hong-Kong.

pandoc-include extends Pandoc to support:

1. include as raw blocks

2. indent and dedent included contents

3. partial include

4. code include

5. Unix style pathname

6. recursive include

7. Yaml header merging

8. header include

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.

Nkf is yet another kanji code converter among networks, hosts and terminals. It converts input kanji code to designated kanji code such as ISO-2022-JP, Shift_JIS, EUC-JP, UTF-8, UTF-16 or UTF-32.

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.

odt2txt is a command-line tool which extracts the text out of OpenDocument Texts, as produced by OpenOffice.org, KOffice, StarOffice and others.

odt2txt can also extract text from some file formats similar to OpenDocument Text, such as OpenOffice.org XML (*.sxw), which was used by OpenOffice.org version 1.x and older StarOffice versions. To a lesser extent, odt2txt may be useful to extract content from OpenDocument spreadsheets (*.ods) and OpenDocument presentations (*.odp).

UTF8-CPP is a C++ library for handling UTF-8 encoded text in a portable way.

The two programs are useful for generating test data, for inspecting binary files, and for interfacing programs that generate textual output to programs that require binary input and conversely. They can also be useful when it is desired to reformat numbers.

• ascii2binary reads input consisting of ascii or hexadecimal representation numbers separated by whitespace and produces as output the binary equivalents. The type and precision of the binary output is selected using command line flags.

• binary2ascii reads input consisting of binary numbers and converts them to their ascii or hexadecimal representation. Command line flags specify the type and size of the binary numbers and provide control over the format of the output. Unsigned integers may be written out in binary, octal, decimal, or hexadecimal.

  Signed integers may be written out only in binary or decimal. Floating point numbers may be written out only decimal, either in standard or scientific notation. (If you want to examine the binary representation of floating point numbers, just treat the input as a sequence of unsigned characters.)

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.

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).

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

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.

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.

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

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.
