Editing Typesetting (section)

==Other text formatters==
GNU [[TeXmacs]] (whose name is a combination of TeX and [[Emacs]], although it is independent from both of these programs) is a typesetting system which is at the same time a [[WYSIWYG]] [[word processor]].

[[SILE]] borrows some algorithms from TeX and relies on other libraries such as [[HarfBuzz]] and [[International Components for Unicode|ICU]], with an extensible core engine developed in [[Lua (programming language)|Lua]].<ref>{{cite web|url=https://sile-typesetter.org/|title=SILE Website|access-date=2023-08-01}}</ref><ref>{{cite web|url=https://tug.org/TUGboat/tb38-1/tb118cozens.pdf|author=Simon Cozens|title=SILE, A new typesetting system|work=TUGboat, Volume 38 (2017), No. 1|date=2017|access-date=2023-08-01}}</ref>
By default, SILE's input documents can be composed in a custom LaTeX-inspired markup (SIL) or in XML. Via the adjunction of 3rd-party modules, composition in [[Markdown]] or Djot is also possible.<ref>{{cite web|url=https://github.com/Omikhleia/markdown.sile|title=Markdown and Djot to PDF with SILE|website=[[GitHub]] |access-date=2023-07-14}}</ref>
