Hi Nala Ginrut,
Thanks for your reply.
I suspect I expressed myself poorly. (execlp "ls" "") replaces guile with "ls", which lists my files and returns me to the shell.
What is some-function, where some-function works like this:
(some-function "ls")
-> "/bin/ls" (I'd settle for #t")
(some-function "asdfasdf")
-> #f
I thought that execl or its friends would be the way to answer that question...
I think there's no such a given function in Guile to do this.
But you can make it in a easy way in Guile:
(catch 'system-error
(lambda () (execlp "asdfasdf"))
(lambda (k . e)
(format #t "oh no~%~")))
PS: Maybe you need #f instead of "format" according to your letter. ;-)
