LyX (styled asLYX; pronounced[ˈlɪks][3]) is anopen source,graphical user interfacedocument processor based on theLaTeXtypesetting system. Unlike mostword processors, which follow theWYSIWYG ("what you see is what you get") paradigm, LyX has aWYSIWYM ("what you see is what you mean") approach, where what shows up on the screen roughly depicts the semantic structure of the page and is only an approximation of the document produced byTeX.
Since LyX relies on the typesetting system of LaTeX without being a full-fledged LaTeX editor itself, it has the power and flexibility of LaTeX, and can handle documents including books, notes, theses, academic papers, letters, etc. LyX'sinterface is structured so that while knowledge of the LaTeX markup language is not necessary for basic usage, new LaTeX directives can be added into the document to support more complex features during editing — though not at the level of full control a full-fledged LaTeX editor can provide.[4][5][6]
LyX is popular among technical authors and scientists for its advanced mathematical modes, though it is increasingly used by non-mathematically-oriented scholars as well[7][8] for its bibliographic database integration[4] and its ability to manage multiple files.[4] LyX has also become a popular publishing tool amongself-publishers.[9][10]
LyX is available for all major operating systems, includingWindows,MacOS,Linux,UNIX,ChromeOS,OS/2 andHaiku. LyX can be redistributed and modified under the terms of theGNU General Public License and is thusfree software.
LyX is a fully featured document processor.[4] It providesstructured document creation and editing, branches for having different versions of the same document, master and child documents, change tracking, support for writing documents in many languages and scripts,spell checking,graphics,table editing and automatic cross-reference (hyperlink) managing. LyX provides automatically numbered headings, titles, and paragraphs, with document outline. It features a powerfulmathematical formula editor with point-and-click orkeyboard-only interface.
LyX has native support for many document classes and templates available in LaTeX through\documentclass{theclass}. User layouts andmodules can be made for those missing. Text is laid out according to standardtypographic rules, includingligatures,kerning,indents, spacing, andhyphenation. It providesBibTeX/BibLaTeX citation support, comprehensivecross-referencing and PDFhyperlinks. LyX can import various common text formats.
Documents can be processed in LaTeX,PdfLaTeX,XeTeX andLuaTeX typesetting systems or exported toXHTML,DocBook,EPUB (via Docbook) and plain text. Versioning is provided through external control systems likeSVN,Git,RCS, andCVS.
LyX supportsright-to-left languages likeArabic,[11]Persian,[12] andHebrew,[13] along with support forbi-directional text.Chinese,Japanese, andKorean languages are supported as well.
Documents can embed calculations viaOctave or Computer Algebra Systems (CAS) likeMaple,Maxima andMathematica. Commands will be forwarded to the external programs and results will be embedded in the document.
Matthias Ettrich started developing a shareware program called Lyrix in 1995. It was then announced onUsenet, where it received a great deal of attention in the following years.
Shortly after the initial release, Lyrix was renamed to LyX due to a name clash with a word processor produced by the companySanta Cruz Operation.[14] The name LyX was chosen because of the file suffix.lyx for Lyrix files.[15]
LyX has no set release schedule. Releases occur when there are important bug fixes or significant improvements. The following table lists the dates of all major releases.[16] For collaboration between different users using the same major release is recommended as LyX file format remains fixed within each major release (e.g. all minor LyX versions 2.3.0, 2.3.1, 2.3.2, ... use strictly the same file format).
