Free TeX software

LaTeX ( or , to rhyme with "blech"), often stylized as '''''', is a software system for typesetting documents, based on the TeX typesetting system. LaTeX provides a high-level, descriptive markup language to use TeX more easily: TeX handles the document layout, while LaTeX handles the content side for document processing. Because the plain TeX formatting commands are elementary, it provides authors with ready-made commands for formatting and layout requirements such as chapter headings, footnotes, cross-references and bibliographies.

TeX (), stylized as '''', is a typesetting program that was designed and written by computer scientist and Stanford University professor Donald Knuth and first released in 1978. The term now refers to the system of extensions – which includes software programs called TeX engines'', sets of TeX macros, and packages which provide extra typesetting functionality – built around the original TeX language. TeX is a popular means of typesetting complex mathematical formulae; it has been noted as one of the most sophisticated digital typographical systems.

MiKTeX is a free and open-source distribution of the TeX/LaTeX typesetting system compatible with Linux, MacOS, and Windows. It also contains a set of related programs. MiKTeX provides the tools necessary to prepare documents using the TeX/LaTeX markup language, as well as a simple TeX editor, TeXworks. The name comes from the login credentials of the chief developer Christian Schenk, MiK for Micro-Kid.

XeTeX ( or ; see also ), sometimes stylized as '''''', is a TeX typesetting engine using Unicode and supporting modern font technologies such as OpenType, Graphite and Apple Advanced Typography (AAT). It was originally written by Jonathan Kew and is distributed under the X11 free software license.

Metafont is a description language used to define raster fonts. It is also the name of the interpreter that executes Metafont code, generating the bitmap fonts that can be embedded into e.g. PostScript. Metafont was devised by Donald Knuth as a companion to his TeX typesetting system.

MetaPost refers to both a programming language and the interpreter of the MetaPost programming language. Both are derived from Donald Knuth's Metafont language and interpreter. MetaPost produces vector graphic diagrams from a geometric/algebraic description. The language shares Metafont's declarative syntax for manipulating lines, curves, points and geometric transformations. However,

LuaTeX, sometimes typeset as '''''', is a TeX-based computer typesetting system which started as a version of pdfTeX with a Lua scripting engine embedded. After some experiments it was adopted by the TeX Live distribution as a successor to pdfTeX (itself an extension of ε-TeX, which generates PDFs). Later in the project some functionality of Aleph was included (esp. multi-directional typesetting). The project was originally sponsored by the Oriental TeX project, founded by Idris Samawi Hamid, Hans Hagen, and Taco Hoekwater.

'PGF/TikZ' is a pair of languages for producing vector graphics (e.g., technical illustrations and drawings) from a geometric/algebraic description, with standard features including the drawing of points, lines, arrows, paths, circles, ellipses and polygons. PGF is a lower-level language, while TikZ is a set of higher-level macros that use PGF. The top-level PGF and TikZ commands are invoked as TeX macros, but in contrast with PSTricks, the PGF/TikZ graphics themselves are described in a language that resembles MetaPost. is the designer of the PGF and TikZ languages. He is also the main develo

ConTeXt, stylised as '''''', is a general-purpose document processor. Like LaTeX, it is derived from the TeX typesetting system. ConTeXt is especially suited for structured documents, automated document production, very fine typography, and multilingual typesetting. It is based in part on TeX, and uses a document markup language for manuscript preparation. The typographical and automated capabilities of ConTeXt are extensive, including interfaces for handling microtypography, multiple footnotes and footnote classes, and manipulating OpenType fonts and features. Moreover, ConTeXt offers extensi

PSTricks is a set of macros that allow the inclusion of PostScript drawings directly inside TeX or LaTeX source code. It was originally written by Timothy Van Zandt and has been maintained in recent years by Denis Girou, Sebastian Rahtz and Herbert Voss (de).

Texinfo is a typesetting syntax used for generating documentation in both on-line and printed form (creating filetypes as , , , etc., and a specific hypertext format, ) with a single source file. It is implemented by a computer program released as free software of the same name, created and made available by the GNU Project from the Free Software Foundation.

__NOTOC__ The computer program pdfTeX, sometimes typeset as '''''', is an extension of Knuth's typesetting program TeX, and was originally written and developed into a publicly usable product by as a part of the work for his PhD thesis at the Faculty of Informatics, Masaryk University, Brno, Czech Republic. The idea of making this extension to TeX was conceived during the early 1990s, when Jiří Zlatuška and Phil Taylor discussed some developmental ideas with Donald Knuth at Stanford University. Knuth later met Hàn Thế Thành in Brno during his visit to the Faculty of Informatics to receive an h

teTeX (stylised as '''''') was a TeX distribution for Unix-like systems. As of May 2006, teTeX is no longer actively maintained and its former maintainer Thomas Esser recommended TeX Live as the replacement. During installation of TexLive it is possible to choose scheme that would include teTeX packages.

knitr is a software engine for dynamic report generation with R. It is a package in the programming language R that enables integration of R code into LaTeX, LyX, HTML, Markdown, AsciiDoc, and reStructuredText documents. The purpose of knitr is to allow reproducible research in R through the means of literate programming. It is licensed under the GNU General Public License.

Sweave is a function in the statistical programming language R that enables integration of R code into LaTeX or LyX documents. It was introduced by Friedrich Leisch in 2002. The purpose is "to create dynamic reports, which can be updated automatically if data or analysis change".

TeX macro package providing phonetic character capabilities

REVTeX, sometimes stylized as '''''', is a collection of LaTeX macros which is maintained and distributed by the American Physical Society with auxiliary files and a user support guide, as part of a "REVTeX toolbox." REVTeX is used to submit papers to journals published by the American Physical Society (APS), the American Institute of Physics (AIP), and the Optical Society of America (OSA). REVTeX is accepted by a few other technical publishers as well.

ΧyMTeΧ is a macro package for TeX which renders high-quality chemical structure diagrams. Using the typesetting system, the name is styled as ''''''. It was originally written by . Molecules are defined by TeX markup.

Chemfig is a LaTeX package used for creating graphical representations of chemical structures, molecules, reaction schemes, and structural formulas. It provides a simple and flexible syntax to define atoms, bonds, angles, rings. It allows for the construction of both organic and inorganic molecules using LaTeX markup.
