Unable to define start-slynk

Nyxt Configuration Questions
1

I tried to define the start-slynk command according to the instructions, but the “my-slynk.lisp” file never loads. I actually did

(load-after-system :slynk (nyxt-init-file "my-slynk.lisp"))

and put the command definition for start-slynk in my-slynk.lisp.

I then tried to define the start-slynk command directly in the lisp-repl in nyxt, but I get the following error:

WARN - Warning: Error on separate thread: Package SLYNK does not
exist. Stream: #<dynamic-extent STRING-INPUT-STREAM (unavailable)
from "(define-...">

I installed nyxt from the Arch AUR. SBCL was installed as a binary from the official Arch repos, and nyxt was built from source.

$ sbcl --version
SBCL 2.1.1

Are you using your distro’s package or a local build?

I’ve had the same problem in the past, and Pierre has been kind enough to guide me through this. Packaged versions of Nyxt don’t pull CL packages from Quicklisp, you need to install them yourself.

What I do here is I create a symlink from ~/.local/share/nyxt/extensions/slynk/ to the location of the the Slynk directory in ~/.config/emacs/. It then gets loaded by (load-after-system).

SBCL is from the distro, nyxt was built from source using an arch PKGBUILD. I remember the install process pulling CL packages from Quicklisp.

However, the directory ~/.local/share/nyxt/extensions/ did not exist for me. I followed your recipe and now slynk is being loaded. I successfully connected to the slynk server using sly-connect from Emacs. :+1:

BTW, how do I discover commands/namespaces from sly? I tried (list-buffers) but it errored out, I had to do (nyxt/buffer-listing-mode:list-buffers).

I’m glad it worked. I also use an AUR package. I’m afraid I can’t help you about your question, as my knowledge of Slynk and CL is very superficial.

The only thing I can think of is this:

in Emacs Sly/Slime REPL, you can press “,” and then type in-package, RET, and then select packages with some prefix. You could type in nyxt and you would have a list of all of the Nyxt packages. From there, you could see what symbols exist in each package. I don’t know if this is a good way to explore the source code. I think it would probably be easier to just download it directly :smiley: and look!
