Asymptote is a powerful descriptive 2D and 3D vector graphics language for technical drawing, inspired by MetaPost but with an improved C++-like syntax. It provides for figures the same high-quality level of typesetting that LaTeX does for scientific text. Asymptote is a programming language as opposed to just a graphics program. It can exploit the best features of script (command-driven) and graphical user interface (GUI) methods. High-level graphics commands are implemented in the language itself, allowing them to be easily tailored to specific applications.
GNU parallel is a shell tool for executing jobs in parallel locally or using remote computers. A job is typically a single command or a small script that has to be run for each of the lines in the input. The typical input is a list of files, a list of hosts, a list of users, a list of URLs, or a list of tables. If you use xargs today you will find GNU parallel very easy to use, as GNU parallel is written to have the same options as xargs. If you write loops in shell, you will find GNU parallel may be able to replace most of the loops and make them run faster by running several jobs in parallel. If you use ppss or pexec you will find GNU parallel will often make the command easier to read. GNU parallel makes sure output from the commands is the same output as you would get had you run the commands sequentially. This makes it possible to use output from GNU parallel as input for other programs.
AutoLaTeX is a tool for managing small to large sized LaTeX projects. The typical AutoLaTeX input file is simply a series of variable definitions in a Makefile for the project. This Makefile was automatically generated by a provided Perl script. The user can easily perform all required steps to do such tasks as preview the document or produce a PDF file. AutoLaTeX will keep track of files that have changed and how to run the various programs that are needed to produce the output. One of the best features of AutoLaTeX is to provide translation rules to automatically generate the figures which will be included into the PDF.
LyX is a document processor that encourages an approach to writing based on the structure of your documents, not their appearance. It is intended for people people who write and want their writing to look great without tinkering with formatting details, font attributes, or page boundaries. On screen, it looks like any word processor, but it uses the TeX engine for printed output and producing richly cross-referenced PDFs. It is stable and fully featured.
TEA is a powerful and easy-to-use Qt4-based editor with many useful features for HTML, Docbook, and LaTeX editing. It features a small footprint, a tabbed layout engine, support for multiple encodings, code snippets, templates, customizable hotkeys, an "open at cursor" function for HTML files and images, miscellaneous HTML tools, preview in external browser, string manipulation functions, Morse-code tools, bookmarks, syntax highlighting, and more.
GNU TeXmacs is a free wysiwyw (what you see is what you want) editing platform with special features for scientists. The software aims to provide a unified and user friendly framework for editing structured documents with different types of content: text, mathematics, graphics, interactive content. TeXmacs can also be used as an interface to many external systems for computer algebra, numerical analysis, and statistics. New presentation styles can be written by the user and new features can be added to the editor using Scheme.
DocBook Doclet creates DocBook XML and class diagrams from Javadoc comments, converts HTML to DocBook, and transfoms DocBook XML into various output formats. It consists of a complete DocBook distribution containing schemas and the DocBook XSL stylesheets. It also integrates Apache FOP as the XSL:FO processor. A Swing application is used to customize the doclet and most of the DocBook XSL parameters and to start the transformations.
Recoll is a personal full text desktop search tool based on Xapian. It provides an easy to use, feature-rich, easy administration interface with a Qt-based GUI. Text, HTML, PDF, PostScript, MS Word, OpenOffice, Wordperfect, KWord, Abiword, maildir, and mailbox mail folder formats are supported, along with their compressed versions and quite a few others. Powerful query facilities are provided. Multiple character sets are supported, and internal processing and storage uses Unicode UTF-8. Stemming is performed at query time and the stemming language can be switched after indexing.
