eLyXer (pronounced elixir) is a LyX to HTML converter. While there are a ton of such projects all over the Web, eLyXer has a clear focus on flexibility and elegant output. LyX is a wonderful text editor that produces beautiful PDF files. Internally, it exports documents to LaTeX, and from there to PDF. Sadly there is not an equivalent “export to HTML” option. With eLyXer, you can convert your master’s thesis, learned article, fascinating novel, or love letter to an HTML page that you can then publish on the Web. It is a standalone tool that does not depend on LyX.
