The two convenience macros, with-parser and with-event don't free up the allocated memory. The forms end with calls to a libyaml delete functions, but those functions don't free the memory for the top-level data structure. Rather, they free up memory for its slots and zero out all the bytes.

The body of the with- forms could either end with a call to foreign-free, or alternatively, expand into a with-foreign-object call rather than calling foreign-alloc.

Trying (cl-yaml:parse "{ a: 1, b: 2}") on Windows fails with the call to INITIALIZE in cl-libyaml.

libyaml.dll is installed from MINGW64 in "c:\msys64\mingw64\bin" (in PATH) (NB. MINGW64 library is called libyaml-0-2.dll, as on *nix systems, I've just copied it to libyaml.dll)

Lisp: SBCL 1.3.6 (installed from roswell)

I tried to install this library via quicklisp on SBCL 1.0.55 and Ubuntu 12.04, but unfortunately it fails with the following error:

 caught ERROR:
    during compiler-macroexpansion of
    (FOREIGN-SLOT-VALUE MARK '(:STRUCT MARK-T) ...). Use *BREAK-ON-SIGNALS* to
    intercept:

     Unknown CFFI type: :STRUCT

Is there anything I can do to get it to compile on this version of SBCL? Sadly I am forced to use this old version...

Hi,

using cl-yaml (cl-yaml-20150505-git, cl-libyaml-20150407-git, sbcl 1.2.16.135, UTF-8 default encoding), evaluating
(yaml:parse "€")
throws an error:
Parsing error at line 0, column 0: incomplete UTF-8 octet sequence.

Evaluating
(yaml:parse "€1234")
returns
"€12"

Maybe in cl-libyaml/src/macros.lisp in (defmacro with-parser ...) the call to with-foreign-string passes the wrong length? Should that be something like the below instead (warning: untested, and my first contact with cffi):

(with-foreign-string ((c-string octet-size) string)
  […]
  (libyaml.parser:set-input-string ,parser
                                   c-string
                                   octet-size)
  […]
  )

Thanks,

Lutz Euler
