What? Oh, you mean like Emacs. Scheme is a beautiful language; it's flexible and trivial to learn. Replacing it with Python would be silly. Besides, Guile Scheme is the designated extension language of the GNU system. Gnucash, dmd (the init system), the Gimp, Guix, gEDA and many more GNU applications all can be hacked in or extended with Guile. In the GNU system Guile Scheme is "mainstream".
No I mean like... surveys the market... nearly everything else. The LISP field is almost non-existent outside of academia and a few companies. Almost nothing mainstream in proprietary or FOSS is built with it. Plus, most programmers hate it. So, using something like in a FOSS app intended to go mainstream is quite a risk.
"Besides, Guile Scheme is the designated extension language of the GNU system."
Oh Ok. That they're pushing people to use an unpopular language at least explains why the apps you cited used it.
" In the GNU system Guile Scheme is "mainstream"."
Nah, most programmers haven't heard of it. Of those that have, I'd bank on only a subset even using it. I'd say it's used by a tiny set of developers, esp extension builders. And for tools who mostly each represent a small amount of developers or users.
You're really making my point for me by redefining the word mainstream to be "barely known software barely making it with a few exceptions." They should consider something that actually is mainstream as an experiment in increasing adoption. Probably some other things to reconsider while they're at it.
You mean like AutoCAD was killed by all the other CAD packages with a more conventional language? I'd like to see such a counterexample. Lisp is only killed by managers who are afraid to hire cheap labour. Like yahoo and their store.
What language is AutoCAD written in? And what percentage of successful products and projects use LISP? That's what I mean. It's the status quo of where LISP is in the marketplace. It's you that have to provide dozens to thousands of counterexampes to even illustrate a trend. They're not there.
Whereas companies adopting PHP, Python, Ruby, Lua, and so on have no time finding help, libraries, or customers. Because they're mainstream and attract such people. See the difference now?
