Automatic Project Initialization When Starting Sly (or SLIME) REPL

ggxx

When I open a CL project in Emacs, I typically do the following.

Open the .asd file.
M-x sly (to open the REPL)
Focus back on the .asd file, C-c C-k (sly-compile-and-load-file).

Focus back on the REPL and type:

(ql:quickload :project)
(in-package :project)    ; Substitute "project" for whatever project I'm in.

Is there a way to automate these steps?

Here's my procedure - not fully automatic, but shorter:

M-x sly
M-x sly-asdf-load-system
Select the system name (with name completion)

I don't bother switching to a package before I actually need it. Which is typically when I am in a Lisp file, and then M-x sly-mrepl-sync (C-c ~) does it efficiently. Some packages I always need are loaded from my ~/.sbclrc anyway.

If you use Quicklisp, the above procedure works only after you have done ql:quickload once. But I think I have seen a Sly extension for Quicklisp as well. I hardly use Quicklisp, so I have no experience to share.

As for further automation, I could easily combine the first two steps into a new Emacs command. I haven't felt the need so far.

Another possibility is defining additional Lisps for Sly (customize sly-lisp-implementations). You can specify a complex command line for starting your Lisp, so you can preload systems etc. For example, my configuration entry for starting ECL is

(ecl ("guix" "shell" "-L" "/home/hinsen/src/guix-kh/" "ecl" "ecl-slynk" "--" "ecl") :coding-system utf-8-unix)

I think this is what I'm going to have to do. I also took a look at sly-asdf and sly-quickload. Thanks for the tips on those.

marcuskammer Emacs has a great package called projects which enables operations on specific git repositories. A project can be a git repository or in Emacs term a VC repository.

I use projects too. I agree that it's nice. It helps me move between projects very easily.

Open project with C-x p p
Choose asd file
M-x sly
(ql:quickload :project)

I dont always need a sly because I create Makefiles in my projects which can be called from within emacs with C-x p c

To launch the REPL automatically when you open a Lisp file for the first time in the session.

(use-package sly
  :hook (sly-mode . (lambda ()
                      (unless (sly-connected-p)
                        (save-excursion
                          (sly))))))

dinomug Why progn? Doesn't save-excursion already establish an implicit progn?

amoroso Yep, I noticed this mistake but after posting it the platform only allowed me to edit it once; it lacks many features (there's no syntax highlighting or media uploads, for example). I'm familiar with Discourse.

dinomug You can edit more than once here. HOWEVER, there seems to be a time limit on edits. After some duration of time passes, the system doesn't allow you to edit anymore. I don't know what that duration of time is.

edit #1
edit #2
edit #3 - verifying (for myself anyway) that I can edit more than once.

dinomug I see.
