LyX is an open source, graphical user interface document processor based on the LaTeX typesetting system. Unlike most word processors, which follow the WYSIWYG paradigm, LyX has a WYSIWYM 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 by TeX.
gedit is a text editor designed for the GNOME desktop environment. It was GNOME's default text editor and part of the GNOME Core Applications until GNOME version 42 in March 2022, which changed the default text editor to GNOME Text Editor.

Doxygen is a documentation generator and static analysis tool for software source trees. When used as a documentation generator, Doxygen extracts information from specially-formatted comments within the code. When used for analysis, Doxygen uses its parse tree to generate diagrams and charts of the code structure. Doxygen can cross reference documentation and code, so that the reader of a document can easily refer to the actual code.
reStructuredText is a file format for textual data used primarily in the Python programming language community for technical documentation.
A lightweight markup language (LML), also termed a simple or humane markup language, is a markup language with simple, unobtrusive syntax.

AsciiDoc is a human-readable document format, semantically equivalent to DocBook XML, but using plain-text mark-up conventions. AsciiDoc documents can be created using any text editor and read “as-is”, or rendered to HTML or any other format supported by a DocBook tool-chain, i.e. PDF, TeX, Unix manpages, e-books, slide presentations, etc. Common file extensions for AsciiDoc files are txt and adoc.
