@abcdw
Unfortunately I did not copy my original error message but it was something like "...variable 'make-custom-textual-input-port' is not defined....". This error appears when I try to Mx arei-evaluate-last-sexp.

make-custom-textual-input-port should be in ice-9/textual-ports.scm but is not in the guile-next that is available today (8/7/2024) from guix.

I had to git clone git.sv.gnu.org/git/guile.git and guix package --install-from-file to get the guile-3.0.10 currently available that does have make-custom-textual-input-port.

With that done it seems to be working.

Your instructions at git.sr.ht/~abcdw/emacs-arei forget to mention you need to specify #:port 7888 when starting the server, otherwise you get a random port. That modification is visible though in the video.

Thanks Andrew

@mbcladwell guile-next has it, I use it. The problem can be in some other place. How do you run ares?

You don't need to specify #:port if you use recent emacs-arei, it automatically picks the port from .nrepl-port file.

I use 7888 in ares local checkout only because I need a quick connect capabilites from other places, where .nrepl-port is not present (for test.scm from arei project for example).

For all other projects I use a random port.

@mbcladwell One of the reasons we don't release Arei 1.0 is because guile is not yet updated in guix, so it requires some hussle to setup correctly: rebuilding guix and other packages with guile-next to work with ares, carefully setting apropriate load paths and so on.

@abcdw
Here I start the server without specifying #:port:

mbc@ins3910:~$ guix shell guile-next guile-ares-rs -- \
guile -c '((@ (ares server) run-nrepl-server))'
nREPL server started on port 7888 on host localhost - nrepl://localhost:7888

again:

mbc@ins3910:~$ guix shell guile-next guile-ares-rs
mbc@ins3910:~ [env]$ guile -c '((@ (ares server) run-nrepl-server))'
nREPL server started on port 62181 on host localhost - nrepl://localhost:62181

again:

mbc@ins3910:~$ guix shell guile-next guile-ares-rs
mbc@ins3910:~ [env]$ guile -c '((@ (ares server) run-nrepl-server))'
nREPL server started on port 51474 on host localhost - nrepl://localhost:51474

again:

mbc@ins3910:~$ guix shell guile-next guile-ares-rs -- guile -c '((@ (ares server) run-nrepl-server))'
nREPL server started on port 7888 on host localhost - nrepl://localhost:7888

As a one liner or with the bash continuation I always get port 7888
Split into two commands I always get a random port. Is this expected?
I thought bash \ was simply continue command on next line but here it seems to affect behavior.
I do get a ~/.nrepl-port file containing the port ID but when I start emacs it seems to ignore it and always looks to port 7888, which is why I thought I need to specify with #:port

@mbcladwell I can't reproduce this behavior it seems the environment is somewhat messed up.

7888 default port is provided by an old ares version.

Check `which guile` you are running, what is in your GUILE_LOAD_PATH, what version of guile `guile --version`.

youtu.be/kPnn22aC5eQ?t=19

It must always be a random port.

If your arei don't pick up a port from .nrepl-port it's maybe because you arei version doesn't support it (guix has old arei), you can C-u C-c C-s C-s to connect with custom port.

@abcdw
I am using guix provided ares/arei
As long as I specify port 7888 (or use one line commands) everything seems to work wrt evaluation so good enough for playing with and evaluating.
Thanks

@mbcladwell I mean guile version inside `guix shell`, they must be different from what you have in you default profile.

No problem.

Wait a bit for Arei 1.0, there are so much quality of life improvements in it :)
