guix-edit shows "Autodoc not available..." w/ 2 REPLs

[myglc2]

Running guix/debian ...

When I do 'M-x guix-edit RET screen RET' I get ...

"Autodoc not available (No Geiser REPL for this buffer (try M-x run-geiser))"

... This puzzles me because guix already has 2 REPLs running ...

 *  * Guile REPL *          1228 REPL             (Guile REPL<1> run)
 *  *Guix REPL*              312 REPL             (Guile REPL run)

So... I wonder, should I really need to start up another REPL?

Or...  is something fishy with my setup?

My .emacs.d/init.el file contains ...

Ouch, I've just answered you on #guix (using sneek).

This error is harmless.  It comes from Geiser and happens when you work
with any scheme file and did not start Geiser REPL.

Guix REPL is used only by "M-x guix-..." commands (to show/install
packages, open package files, etc.).  Guix REPL does not interfere with
a usual editing of scheme files.  I mean "M-x guix-edit ..." just opens
a scheme file with the package definition, and that's it.  If you need a
Geiser REPL (but it's unlikely you need it) while working with this
file, you can start it with C-c C-z.

BTW, if you don't want to use Geiser at all, you can disable it with
(setq geiser-mode-auto-p nil).  With this setting, scheme files will not
enable 'geiser-mode', so you will not see that autodoc error anymore.

No, it's OK.

This should be (require 'guix-autoloads nil t) nowadays.  If you open
*Messages* buffer (C-h e), you can find the following message there:

  (require 'guix-init) is obsolete, use (require 'guix-autoloads) instead.

Try "M-x find-library guix-init" to see what it does.

Thanks, sorry I missed your IRC response. I'm not familiar with
sneek. Can you provide a reference?

I was thinking autodoc might help me understand guix/guile. No?

I am trying to get all the bells and whistles working. In search of a
more perfect setup, I switched back to GuixSD, so comments below relate
to GuixSD. Now, when I 'M-x guix-edit RET screen' & 'M-x run-geiser' I
get auto doc works and I see these buffers:

 MR Name                    Size Mode             Filename/Process
  -- ----                    ---- ----             ----------------
 *  * Guile REPL *           635 REPL             (Guile REPL<1> run)
 *  *Guix REPL*              312 REPL             (Guile REPL run)
 *  *Guix Internal ...       312 REPL             (*Guix Internal REPL*
 open)

Can you comment on whom/what each of these REPLs is used by/for?

If I want to use a REPL, which one should I use?

Would it make sense to add this info to the doc?

OK, but I am going in the other direction, trying to get '8.3 The
Perfect Setup' working. Right now, unless I manually start the 3rd REPL,
these commands: ‘C-c . u’ ‘C-c . b’, ‘C-c . s’, ‘C-c . l’, all produce
'or: Geiser REPL not found' in *Messages*.

Is this normal?

If so, would it be a helpful enhancement if guix-emacs started the 3rd
REPL automatically?

Just join #guix and say hello.  Sneek (the bot) will send you my answer.

Probably.  I think Geiser is a big helper if you work with Scheme in
Emacs.

This is the Geiser REPL that you started manually.  It can be helful
when you work with scheme files.  See the Geiser manual :-)

These REPLs are started automatically when you run one of "M-x guix..."
command.  They are used to get various info (on packages, generations,
licenses), to install packages, etc.  They are not intended to be used
as general Guile REPLs.  There is a reason why there are 2 REPLs instead
of a single one (if you are interested you may "M-x find-library
guix-backend" and read the starting commentary).  Although it would
probably be better to hide the "internal" repl to make it less confusing
for users.

The Geiser one (by default it is called "* Guile REPL *").  Actually,
you are free to do whatever you want (I do whatever I want all the
time).

Sorry, what info do you mean?

Yes, because the Geiser REPL is not started.  These commands are
additions to the Geiser functionality, they work only when you have a
running Geiser REPL.  The same will happen with usual Geiser commands,
like 'C-x C-e' or 'M-.'.

No!  This relates to a usual editing of .scm files.  When you open .scm
file, the Geiser REPL is not started automatically, and it shouldn't!  I
think this would be a malicious behavior.  It's up to a user to decide
how (s)he wants to edit his/her files (in this case: with or without a
help of Geiser).

I mean add an explanation along the lines of what your wrote above to
the documentation.  Maybe in a background or how it works section.

I don't understand why this would be malicious. Could you explain?

Agreed. But I would prefer for Guix by default to start the REPL and
provide a way for me to disable this behavior if I like ;-)

In general, I think it would be better for commands like 'C-c . l' to
work instead of: beeping and giving the message "or: Geiser REPL not
found".  Such messages tend to give the first impression that something
is not working properly :-(

In general, if there are commands that don't work in a vanilla install,
the doc should indicate that they don't work without additional
setup/action, what that setup/action is, and what a user sees if that
setup/action has not been done.

But, as far as possible, I think you should try to make everything work
in a vanilla install, even if it means setting some Guix options in a
way that a power user will not prefer. This way it will be a power user
changing an option and seeing a message like "or: Geiser REPL not
found" and he/she will be able to figure it out ;-)

When I open ".py" file, the Python REPL is not started automatically,
when I open ".scm" file, the Geiser REPL should not be started
automatically, etc.  This is normal!  If you want to have such kind of
interactive programming, you need to start the REPL yourself.

No!  You want to break a normal behavior.  REPLs are not started
automatically when you open a file for editing.

Then running "C-x C-e" (geiser-eval-last-sexp) in .scm buffer should
give you the same impression, as it gives the same error if REPL is not
running.

This is normal, and I mean not only for Guix or for Geiser, but for
these kinds of interactive programming (using REPLs) in Emacs.

BTW I think this Geiser error is quite informative as it tells you what
to do.

The commands work in vanilla install!  All you need is "M-x run-geiser"
as the Geiser error tells.  But the documentation can always be improved
of course.

I think you are just not used to editing files using REPLs.  Did you
ever use Geiser or SLIME or other REPLs in Emacs before?

True, but doesn't a savvy python hacker typically set up their emacs
configuration to start python REPLs automatically? I know this is what I
did when I needed to do a bit of python hacking recently.

I don't care what is "normal." I just want guix to start the REPL.  Is
there any reason other than this not being "normal"?

>>> It's up to a user to decide how (s)he wants to edit his/her files (in
>>> this case: with or without a help of Geiser).

Yes, if you view the file as only a Guile file and emacs as a primitive
editor, this may be so. But this is a guix recipe and you are in guix
mode. So I think guix could do more to help the user.

So 'C-x C-e' in my emacs init file works instead of requiring that I
open an elisp REPL. Is this normal or abnormal?

ess-mode (ESS for R http://ess.r-project.org) provides key bindings to
evaluate R objects and the first you use one, ESS finds R and opens a
REPL. Is the normal or abnormal?

IMO it is strange that when I do 'C-c . l' (a guix key binding) guix
does not help me by opening a REPL if I need one.  This makes me think:
Is guix being stingy?  It guix trying to make me crazy?

Yes, and if I am a Geiser user this would seem normal. But I am a guix
user. I don't know from Geiser. Must I be plunged immediately into
geiser land?

Well, I choose emacs modes that manage the "care and feeding" of REPLs
for me ;-) This is what users expect a good IDE to do. So I think this
is what 'guix edit <package>' should do ;-)

Yes and No. ESS for the past 5 years. Now in Geiser noobie mode.

So back to my question:

>> I don't understand why this would be malicious. Could you explain?

For me "malicious" means intending to do harm.

Is there a way that starting the REPL automatically can cause harm?

Reading the geiser doc I see that ...

(setq geiser-mode-start-repl-p t)

... in emacs init provides this behavior.

Wow, I never knew about this var.  If `t' was its default value, I would
call it a malicious default :-)

We definitely have opposite views on good defaults.

Sure, if you think the documentation is lacking, go for it!  The patches
are always welcome.

I can speak only for myself: I would never do this thing.  Starting a
REPL automatically after a file open is such a strange thing for me,
that I didn't even think before that someone would want it.

Ha, the same for me!  I also don't care what is normal, and I always
change default behaviour to what I like.  The reason is: I don't want to
start a REPL automatically.  And I really think you are in minority with
your wish.

I'm very sorry for not responding to the rest (you write a lot! :-)).
The bottom line: I don't like when a REPL is started automatically after
a file open, and I think (it's just my impression) that most people
don't like it as well.

Moreover, even if you vision of default behaviour is right, I think you
should "attack" (in a good sense) Geiser to change the default value of
'geiser-mode-start-repl-p' variable that you discovered.

NP. I appreciate what you did write ;-)

Your view may well be held by most Geiser users since the default is to
NOT START a REPL ;-)

I wouldn't argue this to the Geiser maintainers because I _don't feel
qualified_ to comment as a Geiser user ;-)

OTOH, I _do feel qualified_ to comment as a _new Guix user_ ;-)

More specifically, a _new Guix user with no prior Geiser/Guile
experience_ but whom is weirdly sympathetic to the Guix enterprise,
possibly as a result of having written a masters thesis on
Maclisp/PDP-10/ITS.

I can say definitively that it would have made Guix easier for me to
start using if you started the 3rd REPL automatically ;-)

Meanwhile, I have put '(setq geiser-mode-start-repl-p t)' in my emacs
init file. I will be sure to let you know when I remove it ;-)
