I edited a Bazaar version-controlled file in Emacs 23 and pressed C-x v v to commit the file. After entering the comment and pressing C-c C-c, I received a message that the working tree was out of date and that I should run bzr update. Wanting to "do everything" from within Emacs, I then pressed C-x v + (to run vc-update) but received a message: "Sorry, merge-news is not implemented for Bzr". The same message resulted after entering M-x vc-update. I ran the update from the command-line from outside of Emacs. Any ideas? Why is the command running "merge-news"?

I have run into issues using the emacs server started when I log in and emacsclient. Specifically, I use the same emacs server for different R projects things get ugly and commands from different projects end up going to the same R session.
My work around is to invoke a second server with /usr/bin/emacs --daemon=Rmd-1 when I log in. I have a bash script written such that the first .Rmd file I work with attaches to this daemon and then the command /usr/bin/emacs --daemon=Rmd-2 is issued. If I end up working with a second .Rmd file, then this server is used and a third server is started with /usr/bin/emacs --daemon=Rmd-3 and ready to work with another .Rmd file if needed.
This works pretty well except for one thing. Because after many years I am hard wired to end my emacs session using C-x C-c by the end of the day I have many emacs servers running. I'm looking for a way to trigger save-buffers-kill-emacs when the C-x C-c command is given in an emacsclient running on a daemon matching "Rmd-[0-9]+". I can't see any emacsclient options that would do that and I'm at a loss as to how to edit my custom.el file.
Can some one help me?
(note I'm running GNU Emacs 27.1 (build 1, x86_64-pc-linux-gnu, GTK+ Version 3.24.30) on Ubuntu 22.04)
Drawing on McNisse's suggestion, adding the following to my personal.el file seems to give me the desired behavior.
;; Remap C-c C-x if daemon name matches "Rmd-[0-9]+"
;;
(cond
((string-prefix-p "Rmd-" (daemonp))
(global-set-key (kbd "C-x C-c") 'save-buffers-kill-emacs)
)
)
My environment:
OS: Linux CentOS 7 (x86_64)
PostgreSQL version: 10.5
Emacs 26.1
I use Emacs as the external editor in postgresql (set in my EDITOR environment variable). So whenever I type in psql shell, \e it opens Emacs where I can write/modify queries, views, functions, etc.
If I understand correctly, once Emacs is open, when I enter C-x C-s, that is, I save and then I quit C-x C-c, the content edited in Emacs is transferred to the query buffer to be parsed and executed (assuming it contains semicolon at the end). So basically each time I have to run \e then edit, then save and quit the editor to get the job done.
Now, given that I use Emacs for multiple programming languages, I've rather a big init file. As a result, it takes several seconds to start Emacs (both in -nw and GUI mode). Obviously this is quite annoying given the number of times that I have to open and quit the editor while I'm using \e in psql.
So my question is: Is there any way to let the external editor remain open and continue working with the same editor for further queries and somehow decide to transfer the result to query buffer without needing to quit the editor?
Run emacsclient instead of emacs. I have a script at ~/bin/editor:
#!/bin/sh
exec emacsclient -c -a '' "$#"
And then I set export EDITOR=$HOME/bin/editor in my ~/.bashrc.
The upshot is you only start Emacs once, and every time you run $EDITOR, it just attaches to the same Emacs session.
Also, I do
(global-set-key (kbd "C-x C-c") #'delete-frame)
(global-set-key (kbd "C-x C-S-c") #'save-buffers-kill-emacs)
so C-x C-c just deletes the frame instead of killing Emacs.
Just save the query to a temporary file, for example /tmp/q.sql and run \i /tmp/q.sql from psql multiple times from a second terminal.
Is there any way to have Emacs display everything that is happening when running term / eshell?
For example, when I try to build Emacs in the tmp directory, there should be a downloading message in the terminal window that tells me the status. However, nothing is displayed. I believe it might be silently doing the job, but I want to see what the normal terminal window application usually displays when running?
M-x eshell
$ cd /tmp
$ bzr branch --stacked bzr://bzr.savannah.gnu.org/emacs/trunk emacs-trunk

Inspired by Git as when you type "git commit", it opens an Emacs or Vim session for you. I'm writing an Erlang escript, and I want it to open an Emacs session at the end of the execution of the escript. I've tried
os:cmd("emacs -nw file.txt")
but it doesn't seem to work. Evaluating the above command within the Erlang shell yields
"emacs: standard input is not a tty\n"
One way to do this is to keep an Emacs running with server mode (put (server-mode) in your ~/.emacs), and call emacsclient instead of emacs from Erlang. That will open the file in the existing Emacs session. emacsclient exits and returns control to your Erlang program once you hit C-x # in Emacs.
How can change this behaviour:
C-s — start incremental search
type word — misprint the last character
Backspace — Oops! incremental search disappears, and I actually delete 1 character from the buffer.
to that one:
C-s — start incremental search
word — misprint the last character
Backspace — delete the last d character
type k — work — correct, and continue the search
I run Emacs in text terminal via SSH in PuTTY.
Operating system version: 2.6.16.60-0.58.1.1882.3.PTF.638363-smp #1 SMP Wed Dec 2 12:27:56 UTC 2009 x86_64 x86_64 x86_64 GNU/Linux
Emacs version: GNU Emacs 23.2.1 (x86_64-unknown-linux-gnu, GTK+ Version 2.14.6) of 2010-07-16
With the -q option, Backspace sent by PuTTY is just C-h, and it acts like C-h, but in my .emacsfile I it bind to delete-backward-char:
(global-set-key [(control h)] 'delete-backward-char)
Try this:
(define-key isearch-mode-map [(control h)] 'isearch-delete-char)
What you should do is configure PuTTY to send C-? (byte 127) for Backspace instead of C-h (byte 8). This is the setting that works best in most circumstances. See the
PuTTY manual.
If you changed the PuTTY setting to send C-h because some other application didn't work, check that your terminal settings are correct on the server. The setting is often correctly autodetected, but sometimes you may need to add stty erase '^?' to your shell configuration file (.bashrc or similar) on the server.
If you really absolutely have to have Backspace send C-h, then globally rebinding C-h isn't sufficient. Instead, add (normal-erase-is-backspace-mode 1) to your .emacs. See the Emacs manual.
How you should use Emacs:
C-s - start incremental search
type word - misprint the last character
M-e - goes into edit-search-word-thing-mode-in-minibuffer :-)
correct the typo
C-s - continue incremental search
