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 https://github.com/yitzchak/common-lisp-jupyter/issues/78 On Tue, 18 May 2021 at 16:58, Guillaume Le Vaillant <g...@posteo.net> wrote: > > Hi Jack, > > I guess it will be easier to just add a phase writing the "kernel.json" > file in the right place.
