Use case: The paths to LaTeX has changed on El Capitan,
which makes it difficult to choose a default path, that works
for all.
Addressing that particular use-case (following the motto that one should
test the functionality rather than switch on the version), and if a
system call is OK, then adapting Stephen De Gabrielle's example you
could try
#lang racket/base
(require racket/system racket/port)
(let-values (((base name must-be-dir?)
(split-path
(string->path
(with-output-to-string (λ ()
(system "which tex")))))))
(printf "binaries in ~a~%" base))
or call out to "tlmgr conf" or one of its subcommands (if your
installation is based on TeXLive). This would obviously work on other
unixes, and there might be a path-searching equivalent on Windows, too.
All the best,
Norman
