CVAssistant
Whether you're looking for a job or trying to help a friend to find one, CVAssistant is the number one tool for you. It helps you by preparing resumes and cover letters and organizing your job application process. It: Stores all your skills and experiences. Creates resumes tailored for each job you apply. Creates cover letters summarized to match each job advertisement. Keeps a history of job applications so you are ready when you receive a phone call. Write resumes in your language. All languages are supported! It's a free and open source software which you can easily download to your computer and start using it out of the box. CV Assistant helps you create specialized resumes in Word .docx format fast and easy. The idea is to have a master resume with all skills and experiences in it. Then based on skills mentioned in the job advertisement, export a clean but well formatted word .docx file as a summarized resume with only relevant skills in it. This increases your chance of getting a job interview as most companies are using Applicant Tracking Software (ATS) or at best hiring managers which may be unaware of similarity between phrases like skilled in MS Word, familiar with Microsoft Word and Fully experienced with office suites. So job seekers need to create specialized resumes for each and every job position with the same wordings used in the advertisement. Add all your skills to CV Assistant, pick only relevant ones. It also creates cover letters! Again, write all possible sentences, and select those relevant ones per job post. CVAssistant helps you free of charge and this software remains for free!

Diffutils Heckert gnu.tiny.png
A group of utilities that displays difference between and among text files. 'diff' outputs the difference between two files in any of several formats. If the files are identical, it normally produces no ouput; if they are binary (non-text) it normally reports only that they are different. 'cmp' shows the offsets and files numbers where two files differ; it can also show, side by side, all the characters that differ between the two files. 'sdiff' merges two files interactively. 'diff3' shows differences among three files. If two people have made independent changes to a common original, diff3 reports that difference between the original and the two changed versions, and can produce a merged file that contains both persons' changes along with warnings about conflicts.

This is done with XML Pipelines, an approach that supports XSLT, breaking up content over headings or sections, and saving those results to multiple files (e.g., chapter1.html, chapter2.html…). The result is returned in a .zip file.
Dot-mode
dot-mode is a minor mode for GNU Emacs that emulates the `.´ (redo) command in vi. It was written so that vi users no longer have an excuse for not switching to emacs…
Dot2Tex
The purpose of dot2tex is to give graphs generated by the graph layout tool Graphviz, a more LaTeX friendly look and feel. This is accomplished by:
  • Using native PSTricks and PGF/TikZ commands for drawing arrows, edges and nodes.

You can also create your own style via templates.
Dvipng
'dvipng' makes PNG graphics from DVI files as obtained from TeX and its relatives. It is the fastest bitmap-rendering code for DVI files; on a fairly low-end laptop, it takes less than a second to generate 150 one-formula images. Furthermore, it does not read the postamble, so it can be started before TeX finishes. There is a -follow switch that makes dvipng wait at EOF for further output, unless it finds the POST marker that indicates the end of the DVI. It supports PK and VF fonts, color specials, and more.
E3
e3 is a full-screen, user-friendly text editor with an interface similar to that of either WordStar, Emacs, Pico, Nedit, or vi. It's heavily optimized for size and independent of libc or any other libraries, making it useful for mini-Linux distributions and rescue disks. There is also a separately distributed version written in C which supports some other Unix versions and CygWin. It is also possible to use regular expressions by using child processes like sed. e3 has a built in arithmetic calculator. The package now supports the ARM Risc CPU, amking it the first assembler program (on user layer) written for 2 different processors (Cisc vs Risc).
EMacro
EMacro is a .emacs that easily configures Emacs and XEmacs on most platforms, without any elisp programming.
EXtrans
eXtrans translates XML documents into other formats or representations. It can output formats HTML, XML, LateX, pictures, sound, or anything else that the python language can manipulate. Those translations are driven by abstract translators (xtrans scripts) embedding python code. The translators are easy to write, since the underlying system habdles all the complicated details of XML parsing, reference resolving, file management and even python programming in a way transparent to the user. This distribution includes GimpClient, a python module for communicating with Gimp. Through it, xtrans scripts can efficiently access a powerful graphics program.
Earm2ipa

Users can access many commonly-used functions without learning the "chords" or multiple keystrokes that Emacs uses by default.
Ed Heckert gnu.tiny.png
Ed is a line-oriented text editor: rather than offering an overview of a document, ed performs editing one line at a time. It can be executed both interactively and via shell scripts. Its method of command input allows complex tasks to be performed in an automated way. GNU ed offers several extensions over the standard utility. The original editor for Unix was the most widely available text editor of its time. For most purposes, however, it is superseded by full-screen editors such as GNU Emacs or GNU Moe. N.B. This pacakge also contains a restricted version of ed, red, that can only edit files in the current directory and cannot execute shell commands.

EncNotex
EncNotex is a free multiplatform software, which runs natively on GNU/Linux, Windows and macOS, that is useful to write and to manage a file of strongly encrypted textual notes and tasks. It’s aim is to grant the user an highly secure tool to manage very confidential data. For this reason EncNotex uses the AES 256 bit encryption, cipher mode CBC and SHA 512; the user cannot save unencrypted data on the disk, but only copy it in the clipboard; the required password to encrypt a file is necessarily 10 characters long or more, chosen at least from three of these four groups: small and upper case letters, numbers and other characters (asterisk, brackets, etc.); optionally, the password used to save a file could be forgotten by the software and typed again by the user each time a file is to be saved, so that the same password does not remain in the computer’s memory while the software is being used. A file of EncNotex is a textual encrypted file containing many notes (no database is used). To grant a perfect compatibility of data among the different platforms and to be very fast even with big amount of data, EncNotex has a very simple structure of notes. They cannot have pictures inside nor attachments, but their text can be formatted in bold, italic and underline. Every note has a title, a list of tags (keywords) separated by comma and space, a date and a free-length text, and can be printed. The title and the date of every note is shown in a read only grid on the left of the interface of the software, and a note can be shown selecting its title in this grid. Furthermore, in the same grid the title of a note can be indented or deindented, to make it a subnote of the previous one, or moved up and down, along with its possible subnotes. At the left of the text of the notes there is an outlook of its titles, which can be used to reach easily one of them, and of the possible tasks along with their deadline. The tasks of all the notes of a file can be summarized in a list, sorted, filtered and copied in the clipboard to be pasted in a spreadsheet, or saved in csv or ics format. It's possible to search for a note within the titles, the tags, the dates and the texts. A note or all the notes of a file can be copied in the clipboard in HTML format and then pasted in a word processor maintaining the possible HTML tags. Finally, two independent backup files are automatically created when a file is loaded and when it's saved.
Epix

A permission system also makes it useful as a help-desk application, bug-tracking database, or documentation system.
Fig2ps
'fig2ps' converts xfig files to PS or PDF, processing text using LaTeX. It is intended to help typeset good quality documents, where the font on the pictures is exactly the same as the font in the text. You compile the picture only once and not every time you compile your LaTeX file (as with other xfig exporters such as eepic); this makes it much faster with complex pictures. It should work with LyX.
File
File attempts to classify files depending on their contents and prints a description if a match is found.

All programs are wired up together automatically providing distributed communication, either through text, images, or games. The source code to all applications is available immediately to instantly clone and modify.
Fldiff
'fldiff' is a graphical diff program that shows the differences between two files/directories, or a file/directory and a CVS or Subversion repository. It is inspired by xdiff (Motif-based) and xxdiff (Qt-based), whose choice of GUI toolkit has hampered their portability to many of the systems.
Flowblade
Flowblade Movie Editor is designed to provide a fast, precise and as-simple-as-possible editing experience. Flowblade employs film style editing paradigm in which clips are usually automatically placed tightly after the previous clip - or between two existing clips - when they are inserted on the timeline. Edits are fine-tuned by trimming in and out points of clips, or by cutting and deleting parts of clips. Film style editing is faster for creating programs with mostly straight cuts and audio splits, but may be slower when programs contain complex composites unless correct work flow is followed.
Flpsed
flpsed is a WYSIWYG pseudo PostScript editor. "Pseudo", because you can't remove or modify existing elements of a document. But it does let you add arbitrary text lines to existing PostScript documents. Added lines can later be reedited with flpsed. Using pdftops, one can convert PDF documents to PostScript and also add text to them. flpsed is useful for filling in forms, adding notes etc.
Flyspell
Flyspell is an Emacs minor mode performing on-the-fly spelling checking. This spawns a single Ispell process and checks each word. The default flyspell behavior is to highlight incorrect words. It was hosted for a long time on INRIA Sophia-Antipolis's site in France, but is now maintained as a part of GNU Emacs.

It provides a user-friendly, easy-to-use glyph editor and it can easily change font metrics (e.g. length, width, and height) and convert between different font formats.
Fontutils Heckert gnu.tiny.png
The GNU Font Utilities (a.k.a. Fontutils) create fonts for use with Ghostscript or TeX. They also contain general conversion programs and other utilities. Some of the programs in Fontutils include bpltobzr, bzrto, charspace, fontconvert, gsrenderfont, imageto, imgrotate… The main purpose of these programs is to form a tool chain to generate Metafont or PostScript fonts from scanned images.
Form Alchemy
FormAlchemy eliminates boilerplate by autogenerating HTML input fields from a given model. FormAlchemy will try to figure out what kind of HTML code should be returned by introspecting the model's properties and generate ready-to-use HTML code that will fit the developer's application. Of course, FormAlchemy can't figure out everything, i.e, the developer might want to display only a few columns from the given model. Thus, FormAlchemy is also highly customizable.
Free Bangla Fonts
The Free Bangla Fonts project is dedicated to creating free, completely Unicode compliant Open Type Bengali fonts. It also aims to be the central resource for getting and developing Free Bengali fonts. The initial goal is to release a full set of Bengali fonts that supports all the major Bengali Yuktakhars (conjuncts). The Akaash set of fonts aims to be such a set. We also plan to convert the other existing Free Bangla (non Unicode compliant) fonts into Unicode compliant Bengali Open Type fonts. Five sets of fonts are currently under development. The Akaash set will have three OTFs, AkaashNormal.ttf, AkaashWide.ttf and AkaashSlanted.ttf. Development is currently going on in the AkaashNormal.ttf, and we aim to move to AkaashWide and AkaashSlanted as soon as possible. The Ani set has two fonts, Ani.ttf and Mitra.ttf. The Mitra font is a monospaced fonts, which is useful in certain specialised applications. The Mukti set has four fonts, MuktiRegular.ttf, MuktiBold.ttf, MuktiNarrow.ttf, and MuktiNarrowBold.ttf. The Likhan and Sagar sets of fonts are also being developed.

It can be extended with the help of plugins, to add features like window splitting.
Gedit
gedit is a text editor for the GNOME Desktop. It is designed to be simple, light, and fast, but its plugin system can give you incredible power as well. Complete GNOME integration is featured.
Geiriadur
'Geiriadur' combines a dictionary lookup engine and a dictionary editing system. It's developed as a tool to create Welsh-Russian and Russian-Welsh dictionaries, but it can also be used for other languages. It consists of two components: a dictionary CORBA server and the Web interface for it. The system works through "words" and "translations". A "translation" is a pair of words or a word with explanation; a "word" means a string of letters without a space, possessing independent meaning in some language. Words can have transcription, attributes (gender, aspect etc.), and "stems" and irregular forms. Regular forms are produced dynamically during a search from "stems" and "endings". The system understands mutations and different spellings (American English, Middle Welsh etc.) If a direct search (with the first word in translations table) yields no results, the system performs an inverse search or asks the user to try a cross-search through a third language.
Gfe
GNU Font Editor (GFE) is a graphical font editor based on GTK+ the GIMP Toolkit. It is easy to use and will eventually support many font types. Currently it supports BDF (bitmap distribution format) font files, that can be converted to many other formats easily.
Gfontview
gfontview is a Font Viewer for outline fonts (PostScript Type 1 and TrueType). It lets you view uninstalled fonts. It will display all fonts present in the chosen directory in a list, with a preview of the font in the main window. It allows printing samples and font catalogs. 'gfontview' also allows you to display a particular character or string of a font in an own window, thus allowing a comparison between several fonts with a particular string sample. This character or string can be antialiased (smoothed).
Ghex
GHex is a simple binary editor. It lets users view and edit a binary file in both hex and ascii with a multiple level undo/redo mechanism. Features include find and replace functions, conversion between binary, octal, decimal and hexadecimal values, and use of an alternative, user-configurable MDI concept that lets users edit multiple documents with multiple views of each.

Glark
'glark' offers grep-like searching of text files, with very powerful, complex regular expressions (e.g., "/foo\w+/ and /bar[^\d]*baz$/ within 4 lines of each other"). It also highlights the matches, displays context (preceding and succeeding lines), does case-insensitive matches, and automatic exclusion of non-text files. It supports most options from GNU grep.
Glatex
glatex is a small program designed to help you to edit your LaTeX document files (sources, styles, bibliography, figures, postscript images, etc.). It maintains a list of all your editable files in order to allow you to edit them quickly. But you can also launch the compilator, viewer, and print commands, and it allows you to have document templates for creating new projects. It is not intended to manage the files themselves. For example, if you move a file from one directory to another, you'll have to remove it from the list and re-add it from its new location.
Glimmer
Glimmer is a code editor that can be used with almost any language. It uses the GTK+ widget set adn the GNOME libraries. Current features include drag and drop support, syntax and bracket highlighting, the ability to build from within the editor, the ability to save sessions of different code files open at once. It supports for more than 20 languages, and is completely scriptable with Python. This project was formerly known as 'code commander.'
Glossword
Glossword is a system to create and publish online multilingual dictionary, glossary, or encyclopedia. It includes multiple language support, themes, a powerful administration interface, built-in search and cache engines, export/import dictionaries in XML and CSV format, and W3C-validated code. It is useful for any kind of dictionary, including sites with game cheat codes, online translators, references, and various CMS solutions.
Gman
Gman is a user-friendly graphical front end for the man system mostly designed for the new users of GNU/Linux. It can help a newbie find specific information or browse other man pages. It is particularly useful as a replacement for xman. Gman's most basic job is to build a database for all the man pages and display them (or part of them) as a list. When the user decides to read a specific man page, gman will launch a xterm window and call the traditional man system to display the man page in the window.
Gnotepad+
A simple HTML and text editor for UNIX-based systems running X11 and using GTK and/or GNOME. It was designed to have as little bloat as possible while retaining the features of a modern GUI-based text editor. It remains small for the number of features it contains, and will remain that way. Features includes multiple windows and multiple documents, a complete preferences system, HTML tag insertions and editing dialogs, unlimited redo and undo, autosave, file locking using fcntl() of flock(), and the ability to drag and drop files between gnotepad+ and other applications. This project was a GNU package. It has since been decommissioned and is no longer developed.
Gnudos Heckert gnu.tiny.png
GnuDOS is a set of programs designed to help new users of the GNU system in growing accustomed to the system, particularly users who might be coming from a DOS background. It consists of a file manager, a text editor and a form designer for the console as well as a core library for building similar utilities:
  • The core library (corelib) contains four utilities: Kbd (for keyboard handling), Screen (for screen drawing), Dialogs (for dialog boxes/window drawing), and Strings (for strings functions).
  • The software applications are three: Prime (console file manager), Mino (console text editor), and Fog (console form designer).
Gnun Heckert gnu.tiny.png
GNUnited Nations is a build system for translating the web site at www.gnu.org. It works via template files, which allow changes to be merged into individual translations of a page, from which the final HTML is generated. In effect, this helps to keep all translations of a page up-to-date. See also the GNU Web Translation Coordination organizational project.

Each user has its own colour (changeable) to be identified by others. There are IRC-like Chat for communicating with your partners, syntax highlighting for most programming languages, session password protection, multiple documents in one session and the drag'n'drop of documents
Gregorio
The Gregorio project offers tools for the typesetting of Gregorian chant. These tools include:
  • gabc: a brief notation for representing Gregorian chant
  • GregorioTeX: a TeX style for typesetting scores
  • GregorioXML: an XML representation of a Gregorian chant score
Grep Heckert gnu.tiny.png
Grep is a tool for finding text inside files. Text is found by matching a pattern provided by the user in one or many files. The pattern may be provided as a basic or extended regular expression, or as fixed strings. By default, the matching text is simply printed to the screen, however the output can be greatly customized to include, for example, line numbers. GNU grep offers many extensions over the standard utility, including, for example, recursive directory searching.
Groff Heckert gnu.tiny.png
Based on a device-independent version of `troff,' `groff' (GNU Troff) is a document processor which reads plain text and formatting commands, produces formatted output from them, and then outputs it to another device. The package is essential for viewing online manual pages. Output can be produced in a number of formats including plain ASCII and PostScript. All the standard macro packages are supported.
Gtkdiff
A diff front end program using gtk+, primarily used as a front end to the 'diff' command to compare files. It has diff3 and merge features.
Gummi
Gummi is a lightweight LaTeX editor written in Python/GTK+.
HSpell
The Hspell project is a free Hebrew linguistic project. Its first aim is to create a free Hebrew spell-checker, and a fully functional and already useful release 0.2 is now available (see below). However the databases and algorithms developed by the Hspell program could also be used as a morphology engine (for example, for search engines), and in the future (with much more work) for advanced things like Hebrew speech synthesis (for the blind who use a free operating system, but also useful for the general population)
HTML GenToc
HTML::GenToc lets you specify significant elements that will be hyperlinked to in a Table of Contents (ToC) for a given set of HTML documents. It does not require those documents to be strict HTML, which makes it suitable for using with templates, included files, and meta-languages such as WML or PHP.
Hashed Text Utilities
This is a candidate for deletion: Links broken. Email to maintainer broken. Poppy-one (talk) 12:50, 3 August 2018 (EDT) Hashed Text Utilities is a small set of programs reimplementing the classic comm, diff, uniq, and cksum programs. The advantage is that for comm and uniq files don't have to be sorted. diff can work with extremely huge files (with some limitations). cksum calculates a checksum of either the whole file or each line separately.
Header Browser
Header Browser helps you to create documentation from your C/C++ header files. It is similar to JavaDoc, Doc++, or KDoc, but it doesn't just create documentation pages; it allows you to really browse your APIs using a five columns view like NeXT's HeaderViewer. Documentation can be generated in several formats, including TexInfo for PostScript, DVI, PDF, manpages, printable HTML, etc.

GNU Health is part of GNU Solidario, an NGO offering health and education to the underpriveledged through free software: http://www.gnusolidario.org
Help2man Heckert gnu.tiny.png
Help2man is a program that converts the output of standard --help and --version command-line arguments into a manual page automatically. It lets developers include a manual page in their distribution without having to maintain that document. Since Texinfo is the official documentation format of the GNU project, this also provides a way to generate a placeholder man page pointing to that resource while still providing some useful information.
Highlight
Highlight is a universal source code to HTML, XHTML, RTF, TeX, or LaTeX converter. (X)HTML output is formatted by Cascading Style Sheets. It supports Bash, C, C++, C#, COBOL, Java, Perl, PHP, and 40 more programming and markup languages. It is also possible to easily enhance the parsing database.

Imediff2
Imediff2 merges two (slightly different) files interactively with a user-friendly fullscreen interface in text mode. It shows the differences between the two files (in color if the terminal supports them), lets you scroll the file, and toggles changes between the old and new versions one by one. Unlike split screen based merge tools, it shows only one version at a time, making it more WYSIWYG.
Indexed PDF Creator
Indexed PDF Creator creates indexed PDF documents from text files. It was primarily written as a utility to convert old mainframe print formats to something that can easily be posted on the Web. It allows indexing, customizing page settings, font size, font face, and superimposing text over an image in the case of using pre-printed forms. It supports unlimited levels of indexing bookmarks in documents and system/user configuration files
Info to html
info_to_html does everything info2html does, and more. Added features include links to other info files, the ability to read compressed files, and a nicer layout.
Info2html
Info files are text files with embedded link directives. They are usually read with emacs or a special purpose browser. 'info2html' looks for a specific info node in an info file and translates it to HTML syntax. Link directives are translated in URLs pointing back to the server. Some icons are provided for link directives and cross references. infocat is a little front-end that gives an index of the .info files available via the local info2html server.
Inkscape
Inkscape is an SVG editor. Supported SVG features include basic shapes, paths, text, alpha blending, transforms, gradients, filters, node editing, PNG export, grouping, and more. It is meant to provide the free software community with a fully XML, SVG, and CSS2 compliant SVG drawing tool.

This directory contains free X11 fonts (BDF format) for all characters that Emacs 20 can handle. They are classified as follows: European, Asian, Chinese, Japanese, Korean, Ethiopic, and misc, with one sub-directory for each category. TrueType fonts are also included.
Isabella
This font, called 'Isabella' is based on the calligraphic hand used in the Isabella Breviary, made around 1497, in Holland, for Isabella of Castille, the first queen of united Spain. It has all of ASCII, Latin-1, Latin Extended A, about a third of Latin Extended B, Latin Extended Additional, plus punctuation, and should work for most languages that use the Roman alphabet. Modern characters (@, for example) were drawn as best possible. The primary design goal was to make such characters look like they were done with a calligraphic pen; the secondary goal was to look like the other characters of the font. The copyright sign, for example, is made by shrinking down the letter "c" and placing it inside a circle. It also has a Euro symbol. 'Isabella' is available in TrueType and PosctScript (author notes that the PostScript version acts oddly in on-screen use).
Ispell
Interactive spell checker that suggests "near misses" to replace unrecognized words.
JDynamiTe
JDynamiTe is a tool which allows you to dynamically create documents in any format from "template" documents. Some typical usage domains of JDynamiTe are:
  • dynamic Web pages creation,
  • text document generation,
  • source code generation...
In fact, it can be useful in any case where pre-defined documents (templates) have to be dynamically populated with data. The main benefit of JDynamiTe is to allow a true separation between data (content), presentation (container) and content generation code (written in Java). JDynamiTe does not include a specific template language, and it is not a complete framework. It is a simple "brick" in your software architecture, a "glue" between your data model and your presentation model.
JEdit
jEdit is an IDE written in Java. Some of its features include:
  • Built-in macro language; extensible plugin architecture. Hundreds of macros and plugins available.
  • Plugins can be downloaded and installed from within jEdit using the "plugin manager" feature.

  • Supports a large number of character encodings including UTF8 and Unicode.
  • Folding for selectively hiding regions of text.
  • Word wrap.
  • Highly configurable and customizable.
  • Every other feature, both basic and advanced, you would expect to find in a text editor.
JEdit Syntax Package
The jEdit Syntax Package is a stand-alone version of the text control from an older version of jEdit. It supports features such as syntax highlighting, bracket matching, rectangular editing, macro recording, and more. The jEdit Syntax Package is lightweight, and meant solely for embedding into Java user interfaces. It does not include some of the nicer features of jEdit, including plugins, and scripting.
Jade Editor
Jade is an Emacs-like text editor that implements most basic Emacs functionality, but is not intended as a straight clone. The Lisp dialect is intended to be compatible with Emacs Lisp, but the interface to the editor internals is not, due to differing philosophies behind the implementations. As a result, most Lisp code written for GNU Emacs will not work; basic GNU Emacs emulation interfaces may be added in the future. Commands are implemented in Lisp, which allows for comprehensive customisation and extension.
Java2html
When given a source java file, program produces an HTML source with syntax highlighting.
JavaDICT
This is a candidate for deletion: Cannot find download. Email to maintainer broken. Poppy-one (talk) 13:23, 6 August 2018 (EDT) JavaDICT is a server for the DICT protocol (RFC 2229), a TCP transaction-based query/response protocol that lets a client access dictionary definitions from a set of natural language dictionary databases. So far it is the only DICT server that lets you access dictionaries stored in a database (currently only PostgreSQL is supported).
Jaxml
Jaxml is a python module designed to automatically generate human readable documents.
Joe
JOE (Joe's Own Editor) is a small, terminal-based, lightweight, emacs-like editor originally written in 1991. Termcap/Terminfo support allows JOE to use any terminal or terminal emulator. Much of the look and feel of JOE is determined by its simple configuration file "joerc". This package is maintained again by its original author, after a period of absence in which another team continued development.
Jove
Jove is a compact, powerful, Emacs-style text-editor. It provides the common emacs keyboard bindings, together with a reasonable assortment of the most popular advanced features (e.g., interactive shell windows, compile-it, language specific modes) while weighing in with CPU, memory, and disk requirements comparable to vi.
Jq
jq accepts a stream of JSON and then transforms it (selecting, iterating, reducing, etc) through one or more filters and then pretty-prints the results. jq is like sed for JSON data - you can use it to slice and filter and map and transform structured data with the same ease that sed, Gawk, grep and friends let you play with text.
Junicode
The Junicode font is designed to meet the needs of medieval scholars; however, it has a large enough character set to be useful to the general user. It comes in Regular, Italic, Bold and Bold Italic faces. The Regular face has the fullest character set, and is richest in OpenType features.
Jupp
Joe, the Joe's Own Editor, has the feel of most PC text editors: the key sequences are reminiscent of WordStar and Turbo C editors, but the feature set is much larger than of those. Joe has all of the features a Unix user should expect: full use of termcap/terminfo, complete VI-style Unix integration, a powerful configuration file, and regular expression search system. It also has nine help reference cards which are always available, and an intuitive, simple, and well thought-out user interface. Joe has a great screen update optimisation algorithm, multiple windows (through/between which you can scroll) and lacks the confusing notion of named buffers.

  • encryption of the text of the selected notes with AES algorithm;
  • search for subjects, notes (also in the text), attachments, dates and tags (keywords);
  • search for more than one tag at a time (in OR condition) and for a range of dates;
  • importation and exportation of single subjects with the related notes and attachments from and to another file of MyNotex;
  • direct importation of an OpenOffice.org Writer or LibreOffice Writer file;
  • importation from Tomboy and Gnote notes;
  • export data in HTML format, which can be easily opened with a word processor like OpenOffice.org Writer or LibreOffice Writer;

  • possibility to insert images in the text of the notes, stored in the directory of attachments;
  • possibility to set the line space and paragraph space of the text of the notes;
  • alarm clock, to be alerted at a specified time;
  • zoom of the text with Ctrl + mouse wheel, or Ctrl + +/-;
  • copy selected text of a note in Latex format.
Finally it is possible to synchronize two different files of MyNotex so that the new, the changed and the deleted subjects, notes and attachments in each one of them are mirrored in the other; at the end of the process, the two files and attachments directories are identical. This feature allows to modify two or more files of MyNotex offline and then connect to the LAN or the Internet and synchronize them, also through a cloud services like Dropbox or Ubuntu One.

OGLFT
The OpenGL/FreeType2 Text Rendering Library (OGLFT) supplies an interface between a font and an OpenGL or Mesa application.It uses the FreeType library to read font faces from their files and renders text strings as OpenGL primitives. Characters can be rendered in a variety of ways, including as raster images, as tessellated polygons and as texture maps. Glyphs can be drawn individually or as a string, and can be rendered using UNICODE characters via the QString class (with Qt support). You can also combine several fonts together in one OGLFT Face to increase the coverage of UNICODE points or for other special effects. Strings can be rotated through any angle, and drawn right, centered or left justified. Additionally each character in a string can be rotated through a given angle.

Support and documentation are available in a number of languages.
OneModel
Today: You can take notes with it. Rearrange them easily, up and down in a list, or up/down in the hierarchy. Link them to each other. Navigate across links with simple keypresses. Make deeply nested lists. Link lists to lists. Compose long paragraphs and attach them. Or do more complicated things if desired, by creating relationship types and using those. Import txt or export txt or html. It's better than the alternatives for some people, because the navigation takes fewer keystrokes, you don't have to read a manual (it's all on the screen, or so I like to think), you can have the same thing in as many places as you want, it is Free (some alternatives are, others are not), and it has immense future potential for becoming a better-structured, much more powerful and flexible wikipedia-like tool, if we work together. Vision: The idea is to have the most efficient personal knowledge organizer (now available in a usable text-based interface), then support mobile access, easy internal automation, and effective sharing and collaboration. Then, to combine efforts and learn as we go until we integrate humankind's knowledge over time. The key differentiators are that it is to be Free, and based on an object model (easily created on the fly as a side-effect of using the system), rather than on massive amounts of words. The knowledge is the same, even if the words can change. One can think of that as "using building blocks of knowledge, starting at an atomic level (i.e. numbers, relationships...), free and efficient." Or, taking the best experiences of online organizer tools and wikis, but more structured, efficient, Free, open, and collaborative; and allowing full individual or organizational control.
OpenDAM
OpenDAM is now a Service As A Software Substitute. The source code is not available from the creator, and (unofficial cloned) repositories on GitHub have not been updated since 2013 so the code there is orphaned. No code on SourceForge.
Orgadoc Heckert gnu.tiny.png
OrgaDoc is a system for easily maintaining a pool of documents between computers. Documents are synchronized by rsync or unison. No database or HTTP server is required.

PDF Editor
Editor for manipulating PDF documents. GUI version + commandline interface. Scripting is used to a great extent in editor and almost anything can be scripted, it is possible to create own scripts or plugins.
PDFResurrect
PDFResurrect is a tool aimed at analyzing PDF documents. The PDF format allows for previous document changes to be retained in a more recent version of the document, thereby creating a running history of changes for the document. This tool attempts to extract all previous versions while also producing a summary of changes between versions. It can also "scrub" or write data over the original instances of PDF objects that have been modified or deleted, in an effort to disguise information from previous versions that might not be intended for anyone else to read.
PDFedit
Complete editing of PDF documents is possible with PDFedit. You can change raw pdf objects (for advanced users) or use many gui functions. Functionality can be easily extended using a scripting language (ECMAScript).
PDFjam.txt
'PDFjam' is a small collection of shell scripts that provide a simple interface to some of the functionality of the pdfpages package for pdfLaTeX. The utilities available are pdfnup, pdfjoin, and pdf90. 'pdfnup' puts multiple document pages together on one physical page at a reduced size, 'pdfjoin' concatenates multiple PDF documents, and 'pdf90' rotates the pages of PDF documents.
PDFrecycle
pdfrecycle creates a PDF file by composing pages from other PDF files. It lets you define PDF bookmarks, scale and rotate pages, put multiple logical pages onto each physical sheet and add metadata. pdfrecycle uses a simple text file format to define the layout and what pages to include. From this input file pdfrecycle creates a LaTeX file and then runs pdflatex to produced the PDF file.
PDFtoPNG
PDFtoPNG is a small utility that can convert documents in the Portable Document Format (PDF) to Portable Network Graphics (PNG).
PE
PE is a very easy tiny console mode text editor that gives the user a simple and direct interface via a command bar. PE is based on the Curses libraries so the text can be displayed black on white. The yellow command bar is displayed on the bottom of the screen. Line and colon counters are provided on the right end of the command bar. Warning messages are displayed on the command bar for critical events. I18n is implemented in v0.5, gettext functions are encodes. UTF-8 encoding up to four bytes is implemented.
Pad
'tpad' (Tcl pad) is a portable clone of the Notepad program. Its goal is to be as similar as possibile to Notepad, except that it doesn't limit the size of the file that is being edited.
Pandoc
Pandoc is a Haskell library for converting from one markup format to another, and a command-line tool that uses this library. It can read Markdown and (subsets of) Textile, reStructuredText, HTML, LaTeX, MediaWiki markup, and DocBook XML; and it can write plain text, Markdown, reStructuredText, XHTML, HTML 5, LaTeX (including beamer slide shows), ConTeXt, RTF, DocBook XML, OpenDocument XML, ODT, Word docx, GNU Texinfo, MediaWiki markup, EPUB (v2 or v3), FictionBook2, Textile, groff man pages, Emacs Org-Mode, AsciiDoc, and Slidy, Slideous, DZSlides, or S5 HTML slide shows. It can also produce PDF output on systems where LaTeX is installed. Pandoc's enhanced version of markdown includes syntax for footnotes, tables, flexible ordered lists, definition lists, fenced code blocks, superscript, subscript, strikeout, title blocks, automatic tables of contents, embedded LaTeX math, citations, and markdown inside HTML block elements (these enhancements can be disabled). In contrast to most existing tools for converting markdown to HTML, which use regex substitutions, Pandoc has a modular design: it consists of a set of readers, which parse text in a given format and produce a native representation of the document, and a set of writers, which convert this native representation into a target format. Thus, adding an input or output format requires only adding a reader or writer. PDF output via PDFLaTeX requires the package texlive-latex-recommended, via XeLaTeX it additionally requires texlive-xetex, and via LuaTeX additionally texlive-luatex.
Pasdoc
Pasdoc generates documentation for Pascal units. It takes descriptions from comments within the source code. Documentation output formats include HTML and LaTeX. Object Pascal, FreePascal and Delphi specific features are supported.
PdfTeX
'pdfTeX' is an extended version of TeX that can create PDF directly from TeX source files and enhance the result of TeX typesetting with the help of PDF. If users do not select PDF output, the program produces normal DVI output; otherwise, it produces PDF output that looks identical to the DVI output. An important aspect of this project is to investigate alternative justification algorithms, optionally making use of multiple master fonts.
Pdfposter
Pdfposter can be used to create a large poster by building it from multple pages and/or printing it on large media. It expects as input a PDF file, normally printing on a single page. The output is again a PDF file, maybe containing multiple pages together building the poster.
Pdftk
'pdftk' is a simple, command line tool for doing everyday things with PDF documents. Use it to merge PDF documents, split PDF pages into a new document, decrypt input as necessary (password required), encrypt output as desired, fill PDF forms with FDF data and/or flatten forms, apply a background watermark, report on PDF metrics, update PDF metadata, attach files to PDF pages or the PDF document, unpack PDF attachments, burst a PDF document into single pages, decompress and re-compress page streams, and repair corrupted PDF files where possible. We link to Debian description and sources of the package, since the upstream website recommends nonfree software for proprietary operating systems.

Perl-reference
Perl-reference is a program to quickly display reference documentation for a Perl function, variable, regexp operator, or language keyword. This documentation is generated from the default Perl POD files, namely perlfunc, perlop, and perlvar. Unlike perldoc, perl-reference relies on documentation generated at compile-time, which results in a much higher response time. It consists of two parts, mkperlreference and pf. 'mkperlreference' is run once during compile-time to create a cache of the Perl POD documentation. This cache consists of plain text files, one for each function, variable, regexp operator and language keyword in Perl. These files are usually installed in /usr/share/perl-reference. 'pf' displays the generated documentation by finding the right cached file and writing its contents to a pager or standard output.
Pfaedit
'pfaedit' is an outline font editor that lets you create your own postscript, truetype, opentype, cid-keyed, svg and bitmap (bdf) fonts, or edit existing ones. It also lets you convert one format to another. This project has been renamed 'FontForge.' Please see http://directory.fsf.org/FontForge.html for the most recent information on this package.

PipeMore
'PipeMore' is a utility to be used as the last of a series of piped commands (like 'more'). It displays STDIN data in a scrolled window where it can be searched or saved, and thereby avoids filling your xterm with temporary output. It differs from 'less' in that you can get a NEW window where the data can stay open so you can refer to it later and usually copy/paste from it.
Pmatch
'pmatch' is an alternative to grep. It has most of the same functionality, but is coupled with the power of PCRE engine in PHP. Features include syntax highlighting, trimming whitespace off the match for easier viewing, showing only the portion of the line that matched (unlike grep, which shows the entire line), and showing the lines around the match to see it in context.

Pspell
The goal of the Portable Spell Checker Interface Library (Pspell) is to provide a generic interface to Spell checker libraries installed on the system.
PyMarkdown
This is a Python implementation of John Gruber's Markdown. It is almost completely compliant with the reference implementation. See Features for information on what exactly supported and what is not. Additional features are supported by the Available_Extensions.
Pymacs
Pymacs is a powerful tool which, once started from Emacs, allows both-way communication between Emacs Lisp and Python. Pymacs aims Python as an extension language for Emacs rather than the other way around, and this asymmetry is reflected in some design choices. Within Emacs Lisp code, one may load and use Python modules. Python functions may themselves use Emacs services, and handle Emacs Lisp objects kept in Emacs Lisp space.
Pyroom
PyRoom is a free editor that stays out your way - and keeps other things out of your way, too. As a fullscreen editor without buttons, widgets, formatting options, menus and with only the minimum of required dialog windows, it doesn't have any distractions and lets you focus on writing and only writing.

ROBODoc
'ROBODoc' is an API documentation tool that extracts specially-formated comment headers from a source file and puts them in a separate file. It lets you include program documentation in the source code and avoid having to maintain two separate documents. ROBODoc formats the documentation in HTML, LaTeX, RTF, XML DocBook, or ASCII format. It can even include parts of the source code. It works with Assembler, C, C++, Java, Perl, LISP, Occam, Tcl/Tk, Pascal, Fortran, shell scripts, HTML, and COBOL; or basically any language that supports comments.
RTFX
'rtfx' converts RTF files into a generic XML format. It focuses on keeping metadata such as style names rather than every bit of formatting. This makes it handy for converting RTF documents into a custom XML format (using XSL or an additional processing step). The package currently supports the following features: page breaks, section breaks, style names, lists (various types), tables, info block, bold, italic, underline, hidden text, strike out, and text color. This package was formerly known as 'rtfm', but was changed due to a naming conflict.
Readline Heckert gnu.tiny.png
The Readline library provides a set of functions for use by applications that allow users to edit command lines as they are typed in. Both Emacs and vi editing modes are available. The Readline library includes additional functions to maintain a list of previously-entered command lines, to recall and perhaps reedit those lines, and perform csh-like history expansion on previous commands.
Refafit
Refafit reduces PDF files recompressing their images, contrasts and resamples scanned documents, extracts plain text, joins and splits files. Useful both in desktop and server environments. Graphical interface is as context menu option to rebuild selected file.
Reftex Heckert gnu.tiny.png
RefTeX is a specialized package for support of labels, references, citations, and the indices in LaTeX. RefTeX wraps itself round four LaTeX macros: \label, \ref, \cite, and \index. Using these macros usually requires looking up different parts of the document and searching through BibTeX database files. RefTeX automates these time-consuming tasks almost entirely. It also provides functions to display the structure of a document and to move around in this structure quickly. RefTeX is bundled with Emacs and available as a package for XEmacs. If you are using an earlier version of Emacs or if you are craving for the latest features and bugs, get the standalone distribution.
Remarkable
Remarkable is a free fully featured markdown editor. With it you can write markdown and view the changes as you make them in the live preview window. You can export your files to a variety of formats. There are multiple styles available along with extensive configuration options so you can set it up exactly how you like.

The result is a text editor that provides a fluid user experience and that is easy and fun to use. It also ensures the safety of your documents at all times.
Sdcv
SDCV is simple, cross-platform, text-based utility for working with dictionaries in StarDict's format.
Se
se ('Screen Editor') is a screen oriented version of the classic UNIX text editor ed. The editor implements many of the commands of ed, but instead of being line oriented, se is screen oriented. The command syntax should be very familiar to users who already know ed. If you get lost, there is a built-in help system which describes many of the available commands. Many configurable options can be loaded from a .serc file. The editor can be run interactively or in a script via the included scriptse utility. se runs on a variety of platforms including GNU/Linux, GNU/Hurd, BSD systems, Haiku, Cygwin, Minix, OpenIndiana, and others.
Sed Heckert gnu.tiny.png
Sed is a non-interactive, text stream editor. It receives a text input from a file or from standard input and it then applies a series of text editing commands to the stream and prints its output to standard output. It is often used for substituting text patterns in a stream. The GNU implementation offers several extensions over the standard utility.
Seealso
'seealso' is a script that searches and prints references in the 'See also' section included at the end of many UNIX manual pages. You can use it to locate documentation or gain familiarity with the commands and functions available on a system.
Shed
'Shed' is a hex editor written for unix/linux using ncurses. It can display each byte as ascii, hex, decimal, octal and binary; changes can be input in all of the above. It has a simple Pico-style interface. The package's memory requirements are mall because files are not loaded into memory (when you edit a file, changes is made directly to disk. The authors urges that you backup your files first). It handles files up to 4Gb.
Shipyard
Shipyard is a module to process data in a format inspired by email headers (RFC 2822). The goal of shipyard is to have a simple, human readable and human writable replacement for CSV that works better for long data and many rows and doesn’t need difficult escaping rules for special characters. It’s called shipyard because that word contains py and doesn’t seem to be taken yet.
Siag
Siag Office is a free office package consisting of the spreadsheet Siag, the word processor PW, the animation program Egon, the text editor XedPlus, the file manager Xfiler and the previewer Gvu. These programs are extensible using Scheme. This package is outdated and no longer maintained.
Skribe
Skribe is a text processor. It is a general purpose text processor that is best suited to writing technical documents such as Web pages or technical reports, API documentation, etc. While it looks like a markup language such as HTML, so there is no need for computer programming skills to use it, it is actually a true programming language based on Scheme, and with high-level features (such as objects, higher order functions, regular and syntactic parsing, etc.). It is the successor of Scheme Scribe.
Slidedown
Generate HTML slides from Markdown.
SmartyPants
SmartyPants is a free web publishing plug-in for Movable Type, Blosxom, and BBEdit that easily translates plain ASCII punctuation characters into smart typographic punctuation HTML entities. SmartyPants can perform the following transformations:
  • Straight quotes into curly quote HTML entities
  • Backticks-style quotes into curly quote HTML entities
  • Dashes into en- and em-dash entities
  • Three consecutive dots into an ellipsis entity
Spell Heckert gnu.tiny.png
A spell checking program which prints each misspelled word on a line of its own. It is designed as a clone of the standard Unix 'spell' program, and implemented as a wrapper for 'Ispell." Spell accepts its arguments as a list of files to read from. Within that list, the magical file name "-" causes spell to read from the standard input. In addition, when called with no file name arguments, Spell assumes that it should process standard input.
Sphinx
Sphinx is a tool that makes it easy to create intelligent and beautiful documentation for Python projects (or other documents consisting of multiple reStructuredText sources), written by Georg Brandl. It was originally created to translate the new Python documentation, but has now been cleaned up in the hope that it will be useful to many other projects. Sphinx uses reStructuredText as its markup language, and many of its strengths come from the power and straightforwardness of reStructuredText and its parsing and translating suite, the Docutils.
Src-highlite Heckert gnu.tiny.png
Source-highlight reads source language specifications dynamically, thus it can be easily extended (without recompiling the sources) for handling new languages. It also reads output format specifications dynamically, and thus it can be easily extended (without recompiling the sources) for handling new output formats. The syntax for these specifications is quite easy (take a look at the manual). Source-highlight is a command line program, and it can also be used as a CGI. Notice that Source-highlight can also be used as a formatter (i.e., without highlighting): you can, for instance, format a txt file in HTML (and it will take care of translating special characters, such as, <, >, &). Since version 2.2, source-highlight can also generate cross references; in order to do this it relies on Exuberant Ctags. These are the output formats already supported:
  • HTML
  • XHTML
  • LATEX
  • TEXINFO
  • ANSI color escape sequences (you can use this feature with less)
  • DocBook
These are the input languages (or input formats) already supported (in alphabetical order):

Stardict-ed
'stardict-ed' is a fork of StarDict, a cross-platform and international dictionary. It can be compiled with or without GNOME libraries (in the second case, it requires only GTK+). Unlike 'StarDict,' it uses libstardict for access to dictionaries, so it works a little faster.
Staypuft
A rounded, sort of marshmallowy, style font that looks something like Comic Sans MS. It's kind of cute, and might be good for frivolous stuff such as birthday cards. It has ASCII, Latin-1, and a few other useful characters: left and right quotation marks (single and double), ellipsis, long dash, and Euro.
