namestring

(namestring pathname)

The namestring of a pathname designator: a pathname value unwraps to the namestring it carries, a string is already one and passes through, and anything else signals. Portable code calls it where a pathname object has to be turned into a string before printing, concatenating or handing it outside Lisp.

uiop:namestring names this same function -- real UIOP re-exports Common Lisp's, and so does this -- and so does uiop:native-namestring (a rontolisp namestring already is the host spelling).

(namestring "/tmp/data.json") is the string itself.

Backend support

All four backends -- one definition in rontolisp source, spliced into the program when it is referenced.
