All this time I assumed that GNU TeXmacs was was a GNU Emacs mode for editing TeX. Turns out it isn’t related to either Emacs or TeX. If only they hadn’t chosen such a doubly misleading name I might have been using this for the past 20 years.
It has been an unfortunate decision. Once in a while the community discuss to change the name, but no convincing proposal have emerged. On the other hand I really hear very few people complaining about JavaScript. So I guess, the name is not all here.
