Hi!

I’m pleased to announce the first release of Guile-zstd:

  git clone https://notabug.org/guile-zstd/guile-zstd
  cd guile-zstd
  git checkout v0.1.0  # or 0d830f53e2a2bb71799aeda4be7101a09d060f99
  git tag -v v0.1.0

The ‘git tag -v’ command checks the authenticity of your checkout.
You may need to retrieve the signing key first:

  gpg --keyserver pool.sks-keyservers.net \
      --recv-keys 3CE464558A84FDC69DB40CFB090B11993D9AEBB5

Guile-zstd provides Guile 3.0/2.x bindings to the zstd (or “zstandard”)
compression library.

You can report bugs and send patches to <guile-user@gnu.org> or on the
web site:

  https://notabug.org/guile-zstd/guile-zstd

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

Great! This is now available in Guile Homebrew as well as guile-lzlib
and guile-zlib.

Btw, I sent a PR to guile-zstd:
