bug#46333: sbcl-common-lisp-jupyter does not install kernel.json

[Sharlatan Hellseher <sharlatanus@gmail.com>]

Hi,

I've checked the r-irkernel and it's coping existing kernelspec ,
which is not useful in this case.

As Guillaume mentioned we could tweak it before installation phase by
using cl-jupyter:install, so here is my draft:

--8<---------------cut here---------------start------------->8---
    (arguments
     `(#:phases
       (modify-phases %standard-phases
         (add-before 'install 'generate-kernelspec
           (lambda* (#:key outputs #:allow-other-keys)
             (let* ((out (assoc-ref outputs "out"))
                    (kernelspec (string-append out
"/share/cl-jupyter/kernelspec")))
               (mkdir-p kernelspec)
               (invoke "sbcl"
                       "--eval" "\"(require :asdf)\""
                       "--eval" "\"(require :common-lisp-jupyter)\""
                       "--eval"
                       (string-append
                        "\"(cl-jupyter:install"
                        ":bin-path" (string-append
                                     (assoc-ref %build-inputs "sbcl")
"/bin/sbcl")
                        ":prefix" out ")\"")
                       "--eval" "\"(exit)\""))
             #t))
         (add-after 'install 'install-kernelspec
           (lambda* (#:key outputs #:allow-other-keys)
             (let ((out (assoc-ref outputs "out"))
                   (kernelspec (string-append out
"/share/cl-jupyter/kernelspec")))
               (invoke "jupyter" "kernelspec" "install"
                       "--name" "cl-jupyter"
                       "--prefix" out
                       kernelspec)
               #t))))))
--8<---------------cut here---------------end--------------->8---

But there could be a potential blocking issue with :prefix key
