sly-macrostep is a SLY contrib for expanding CL macros right inside the source file, like so:
This extension is the work of Jon Oddie, the original author of the excellent macrostep.el library, and Luís Oliveira.
I just ported it to SLY with some minimal renaming and tweaks.
Perform the usual MELPA setup and then select sly-macrostep for installation from the package menu or from M-x package-install.
Once it's done, M-x sly should now bring up a macrostep-enabled SLY.
In .lisp files you can now use C-c M-e or M-x macrostep-expand to expand a macro.
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-macrostep-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/john-oddies-macrostep-library") (add-to-list 'load-path "/path/to/sly-macrostep") (require 'sly-macrostep-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.
