What it is

LyX is a document processor for structured writing, combining TeX and LaTeX capabilities with a graphical interface. It suits work ranging from academic articles, theses, and books to letters, novels, plays, and film scripts. Its equation editor accepts point-and-click input or LaTeX commands and renders formulas on screen. For document organization, LyX includes labels, references, indexes, and bibliography tools, with advanced BibTeX support. Configurable converters handle imports and exports including LaTeX, PDF, PostScript, DVI, ASCII, HTML, OpenDocument, RTF, and MS Word. It supports multilingual documents, right-to-left writing, CJK writing systems, and Unicode. Basic links to Maple, Maxima, Octave, and Mathematica are available, while modules can add Noweb, Sweave, and LilyPond support. LyX works offline on Linux, macOS, and Windows, and supports track changes and external version control systems such as Git. It is free software under the GPL. Windows requires a TeX distribution; Mac installations require a TeX system such as MacTeX.
