Hi Ludo,

that’s pretty cool! Thank you!

Looking at the readme I get the feeling that two little helpers could be
useful:

   (call-with-zstd-output-file "compressed.zstd"
	(lambda (port)
	  (define data
	    ;; Read the input file in memory.
	    (call-with-input-file "input-file.txt"
	      get-bytevector-all))

	  ;; Write data to PORT.
	  (put-bytevector port data)))

  (call-with-zstd-input-file "compressed.zst"
	(lambda (port)
	  ;; Read decompressed data from PORT.
	  ...))

Potentially with streaming added (if that’s possible from the library):

   (call-with-zstd-output-file "compressed.zstd"
	(lambda (outport)
      (call-with-input-file "input-file.txt"
	    (lambda (inport)
          (let loop ((data (get-bytevector-some inport)))
            (when (not (eof-object? data))
              (put-bytevector outport data)
              (loop (get-bytevector-some inport))))))))

Also maybe a minimal representation of the commandline-interface:

   (zstd-compress "input-file.txt" #:output "compressed.zst")
   (zstd-decompress "compressed.zstd" #:output "cleartext-file.zst")

Best wishes,
Arne
