🔭 Finding Lisp

By default, packages are installed for the default SBCL, i.e., the one behind the sbcl command. To pick a different lisp implementation, set the environment variable QOB_LISP to the command name or executable path of the lisp implementation to use:

Steel Bank Common Lisp (SBCL):

$ QOB_LISP="sbcl-2.2.9" qob command

Clozure CL (CCL):

$ QOB_LISP="ccl-1.12" qob command

Embeddable Common Lisp (ECL):

$ QOB_LISP="ecl-1.12" qob command

Note that installed dependencies are scoped on the version of the lisp implementation. So when switching between versions you will have to install the dependencies for each:

$ QOB_LISP="sbcl-2.2.9" qob install
