SXML has been around a while, and makes working with HTML in most Lisps a breeze. See this for example [0].
'((html (head (title "My Title"))
(body (@ (bgcolor "white"))
(h1 "My Heading")
(p "This is a paragraph.")
(p "This is another paragraph."))))
Lisp comes with a built-in templating system: quasiquote. Systems such as SXML (an s-expression representation of XML documents) build on top of that. This takes care of multiple problems with JSX: 1) writing HTML/XML is annoying (remembering to put the close tag in the right place, etc.) 2) JSX is a DSL, not an embedded DSL, so you need new compiler infrastructure to work with it.
Here is a snippet of real code that produces an SXML tree. It generates atom feeds for websites that use a static generator I wrote:
`(feed (@ (xmlns "http://www.w3.org/2005/Atom"))
(title ,(site-title site))
(subtitle ,subtitle)
(updated ,(date->string* (current-date)))
(link (@ (href ,(string-append (site-domain site)
"/" file-name))
(rel "self")))
(link (@ (href ,(site-domain site))))
,@(map (cut post->atom-entry site <>
#:blog-prefix blog-prefix)
(take-up-to max-entries (filter posts))))
Doing it the Lispy way, though, you'd likely use sexprs directly, with maybe some normal macros, so you wouldn't have HTML-like syntax but would have something that worked nicely in your editor.
