sly-package-inferred is an external contrib for SLY that replaces its
completion with a function which is better suited for systems using the
package inferred style.
This package is not available on MELPA yet.
Since this is an external contrib with both Elisp and Lisp parts,
merely loading the Elisp will have little effect. The contrib has to
be registered in SLY's sly-contribs variable for SLY to take care of
loading the Lisp side on demand.
For convenience, the sly-package-inferred-autoloads file takes care
of this automatically. So the following setup in your ~/.emacs or
~/.emacs.d/init/el init file should be enough:
;;; regular SLY setup
(setq inferior-lisp-program "/path/to/your/preferred/lisp")
(add-to-list 'load-path "/path/to/sly")
(require 'sly-autoloads)
(add-to-list 'load-path "/path/to/sly-package-inferred")
(require 'sly-package-inferred-autoloads)In case you already have SLY loaded and running, you might have to
M-x sly-setup and M-x sly-enable-contrib to enable it.
sly-package-inferred should now kick in in Lisp buffers.
