Editing GNU TeXmacs (section)

== Background ==
As a structured WYSIWYG editor and document preparation system, TeXmacs is similar to earlier structured document editors, such as [[Interleaf]] (first release 1985), [[Framemaker]] (1986), [[SoftQuad Software|SoftQuad]] Author/Editor (1988),<ref>{{Cite journal|last=Brown|first=Susan|date=2015-03-01|title=Remediating the Editor|journal=Interdisciplinary Science Reviews|volume=40|issue=1|pages=78–94|doi=10.1179/0308018814Z.000000000106|bibcode=2015ISRv...40...78B |s2cid=144086542|issn=0308-0188|doi-access=free}}</ref> Lilac,<ref>{{Cite journal|last=Brooks|first=K.P.|date=June 1991|title=Lilac: a two-view document editor|url=http://dx.doi.org/10.1109/2.86832|journal=Computer|volume=24|issue=6|pages=7–19|doi=10.1109/2.86832|s2cid=2239112|issn=0018-9162}}</ref> {{ill|Grif (software)|fr|Grif|lt=Grif}} (1991),<ref>{{Cite web|title=GriF SGML Editor|url=https://markupuk.org/webhelp/grif.html|access-date=2020-11-27}}{{Dead link|date=October 2023 |bot=InternetArchiveBot |fix-attempted=yes }}</ref> and Thot;<ref>{{Cite web|title=Thot structured document editor|url=http://opera.inrialpes.fr/Thot/index.html|access-date=2020-11-26}}</ref> there was also academic research into interactive editing of complex typographical constructs represented logically.<ref>[https://spiral.imperial.ac.uk/handle/10044/1/47656 A structured document model], Clement Shin Tai-Yin, PhD Thesis, Department of Computing, Imperial College London, 1989

In the 2000s and 2010s, interest on interactive editing of structured text encouraged the development of programs intended for scholars in the humanities; an example of this is CWRC-Writer, a visual XML editor with "Close-to-WYSIWYG editing and enrichment of scholarly texts with meaningful visual representations of markup".<ref>[http://www.dh2012.uni-hamburg.de/conference/programme/abstracts/cwrc-writer-an-in-browser-xml-editor.1.html CWRC-Writer: An In-Browser XML Editor], G. Rockwell et al., Digital Humanities 2012 Conference</ref>

On another side of the editing and document preparation world, a program for visual interaction with structured texts written in [[LaTeX]] is [[LyX]], which does not aim at WYSIWYG editing but at visual representation of the structure ([[WYSIWYM]]).
