## error when running notmuch from emacsclient, but not from standalone emacs instance

## error when running notmuch from emacsclient, but not from standalone emacs instance

[ricardomartins]

Hello. I'd like to report an error I'm encountering.

I installed notmuch from the arch repositories. I had previously
installed the notmuch package from the MELPA repository, but have since
uninstalled it and the error persists.

When I try to run notmuch from the emacsclient instance (M-x notmuch
<RET>), I get an error
"notmuch count --batch failed
Please check that the notmuch CLI is new enough to support `count
--batch'. In general we recommend running matching versions of
the CLI and emacs interface."

When I run notmuch from an standalone emacs instance, NOT the emacs
client, the same way (M-x notmuch <RET>), I get no errors and notmuch
works fine.

I read all the documentation. Have I missed something? Why am I
experiencing this behaviour?

Thanks

I agree it is strange strange to have problems only affecting
emacsclient. The only thing I can think of off hand is that starting
emacsclient does not reload the emacs initialization file, so make sure
you run both experiments with a fresh restart of emacs.

What is the output of M-x notmuch-version for both emacsclient and emacs?

... and how are you starting the emacs server? Depending on that,
server and standalone may get a different PATH from the environment so
that one uses the system notmuch and the other your personal install.

Both show notmuch version 0.37. 


>> ... and how are you starting the emacs server? 
I started as a systemd user unit. I'm using GNU Emacs 30.0.50
Development version 2f05f48918ec on master branch; build date
2023-01-07. VISUAL and EDITOR environment variables are set to
emacsclient.

Ok, so I tested this. I tried stopping the systemd unit of the emacs
server, opened an emacs instance, and started the server from within
emacs (M-x server-start <RET>). Connected to this server in a new frame
($ emacsclient -nc) and tried executing notmuch again (M-x notmuch
<RET>). This time, it worked like it should. So, definitely an issue
with the systemd unit method of initialization there, although it only
executes /usr/bin/emacs --fg-daemon, so I'm not sure exactly is going on
here that's causing the problem. 

Thanks for helping.

I don't have personal experience with running emacs from systemd, but I
guess it could be worth trying

M-: (executable-find "notmuch")

That will verify that you are not being tripped up by multiple notmuch
executables.

Another thing to try is

M-x notmuch-search <return> tag:inbox <return>

This may give a more helpful error message (or it may work fine,
indicating the problem is really with notmuch count, but the --batch
option is almost 10 years old now, so I think that error checking
probably needs to be updated.

Just a wild guess: have you tried installing the emacs package exec-path-from-shell (from melpa)?
