Open multiple separate terminal buffers with multi-term in Emacs.

Open multiple separate terminal buffers with multi-term in Emacs.

[Hongyi Zhao]

According to the tricks mentioned here,
<https://iloveemacs.wordpress.com/2014/09/10/emacs-as-an-advanced-terminal-multiplexer/comment-page-1/>,
I installed the following packages from melpa: multi-term,
ace-jump-mode, key-chord, and yasnippet. Then I add the following
configuration into my ~/.emacs.d/init.el:

(require 'multi-term)
(require 'ace-jump-mode)
(require 'key-chord)
(require 'yasnippet)

(key-chord-mode 1)
(setq key-chord-one-key-delay 0.15)
(key-chord-define-global "jj" 'ace-jump-mode)

(add-hook 'term-mode-hook (lambda ()
(setq yas/dont-activate nil)
(yas/minor-mode-on)
(add-to-list 'term-bind-key-alist '("C-c C-n" . multi-term-next))
(add-to-list 'term-bind-key-alist '("C-c C-p" . multi-term-prev))
(add-to-list 'term-bind-key-alist '("C-c C-j" . term-line-mode))
(add-to-list 'term-bind-key-alist '("C-c C-k" . term-char-mode))
))

(global-set-key (kbd "C-c t") 'multi-term-next)
(global-set-key (kbd "C-c T") 'multi-term)


Now, I can open two new terminals by pressing:

C-c T
C-x 2

But I noticed that the shell commands issued in one terminal will also
be shown in the other, i.e., they are the identical one. And I want to
open multiple separate terminal buffers, with which I can issue
different shell commands in them respectively and observe the
corresponding executions of them.

Any hints for this problem will be highly appreciated.

You can use `ansi-term' command to open terminal with different programs:

ansi-term is an autoloaded interactive compiled Lisp function in
‘term.el’.

(ansi-term PROGRAM &optional NEW-BUFFER-NAME)

  Probably introduced at or before Emacs version 28.1.

Start a terminal-emulator in a new buffer.
This is almost the same as ‘term’ apart from always creating a new buffer,
and ‘C-x’ being marked as a ‘term-escape-char’.

This below would open 2 different terminals with different shells:

(ansi-term "/bin/bash")
(ansi-term "/bin/zsh")

You can then use argument to invoke new program in new term.

(defun run-with-term ()
  (interactive)
  "Runs new command with term"
  (let ((my-programs '("/bin/bash" "/usr/bin/mc")))
    (ansi-term (completing-read "Program to run: " my-programs nil nil))))

If all you want is to use multiple terminals, you don't need all those packages.
Only multi-term is useful for your purpose. (It's possible to do what you want
without any extra packages, but multi-term makes it easier.)

So before you install ace-jump-mode, key-chord and yasnippet, I strongly suggest
you read about what those packages do and consider whether you really want/need
them.

Now, about your question:

This doesn't actually open two terminals. It opens one terminal and then splits
the window in two windows. Both windows show the *same* buffer, however.

The description of the multi-term package (see <https://melpa.org/#/multi-term>)
says that you can create a new term buffer with `M-x multi-term`, which you have
bound to `C-c T`. So press it once to create one terminal, press it again to
create a second one. If you want to see both terminals at once, open one
terminal, split the window (C-x 2 or C-x 3) and then open a new terminal in the
second window.

But how can I get these terminal buffers to be tiled so that switching
between them is easy?

Based on the author said on GitHub,
<https://github.com/manateelazycat/multi-term>:

I mainly use Aweshell now, but I still maintain multi-term.el, feel
free send PR to me, thank you!

So, perhaps I should also give aweshell
(https://github.com/manateelazycat/aweshell) a try.

That depends. From the looks of it, aweshell is to eshell what multi-term is to
term. The thing is, you have several choices when it comes to running a shell
inside Emacs. There is `M-x shell`, `M-x term` and `M-x eshell`. shell and term
both run a system shell (bash or zsh or whatever you like) as a subprocess and
display the output in a buffer. They have some differences in the way they
interact with Emacs. Details are described in the manual:

https://www.gnu.org/software/emacs/manual/html_node/emacs/Shell.html

Or in Emacs itself: `C-h i emacs RET shell RET`.

Eshell is a shell implementation written in Elisp. That's to say, it's the Elisp
equivalent of bash, zsh, etc. It doesn't run a shell subprocess and everything
it does is done through Emacs (unlike term and shell, which basically just pass
every character you type to the subprocess).

Eshell generally integrates better with Emacs (e.g., you can use Elisp commands
in the shell), but it behaves differently from bash or zsh, so not everything
you know about the shell you normally use carries over.

Which method to use depends on personal preference, the tasks you normally do on
the shell and probably on other factors as well. M-x term is perhaps the easiest
to start with, because everything basically works in the same way as when
running a shell in a terminal emulator such as xterm, rxvt, Terminal, etc. You
just need to know about line mode and char mode, and how to switch between them.
With M-x shell, you don't need to bother with that, but certain things won't
work. (For example, try running `htop` in both.) Eshell is the most emacs-y of
the three. Its integration with Emacs is great and it's a good shell too, but
its command syntax is different once you get to more powerful stuff such as for
loops.

Let us not forget the variable `eshell-virtual-commands' as commands
like `htop' may then be invoked from eshell in terminal.

I want to see all the opened terminals at once, i.e., tiling them in
the Emacs window. How can I write a function that takes as an argument
the number of buffers to open to automate this process?

To be more specific, I find the following code snippet from
<https://stackoverflow.com/questions/2785950/more-than-one-emacs-terminal>:

;Here's a super lightweight little function that you can call to
automatically rename the term you're on, and then start a new term:
(defun new-ansi-term ()
  (interactive)
  (if (string= "*ansi-term*" (buffer-name))
      (rename-uniquely))
  (ansi-term "/bin/bash"))

;Then to bind that within ansi-term, I found this works:

(defvar ansi-term-after-hook nil)
(add-hook 'ansi-term-after-hook
          '(lambda ()
             (define-key term-raw-map (kbd "C-t") 'new-ansi-term)))
(defadvice ansi-term (after ansi-term-after-advice (org))
  (run-hooks 'ansi-term-after-hook))
(ad-activate 'ansi-term)


The above code can open multiple new terminals, but they are located
in different windows, and I don't know how to adjust it to let all
terminals opened using a tiling layout.

Really?  If it doesn't work for you, you might like to `M-x fix-this-bug RET`.

Re: Open multiple separate terminal buffers with multi-term in Emacs.

[Samuel Banya]

My recommendation, use 'vterm' with 'tmux', and your problem is solved for having multiple terminals present in a single buffer. Plus you can detach and re-attach at any time.

As far as 'vterm' is concerned, I noticed the following package:

[Samuel Banya]

Yep, that's the one!

I would recommend that one, since 'vterm' is the best terminal emulator you can use in Emacs (in my opinion) as its support for 'ncurses' type programs is way better than 'ansi-term' by a long shot.

Re: Open multiple separate terminal buffers with multi-term in Emacs.

[Samuel Banya]

Also, forgot to clarify that 'tmux' is a terminal utility that you can install and use on any Linux distribution. 

It is a 'Terminal Multiplexer' which basically means that you can use multiple terminals all at once, and split panes easily.

I'm going to link the playlist I used to learn 'tmux' from YouTube from a while back, would recommend it as I think he gets into how to customize 'tmux' as well since 'tmux' is amazing when you customize it to suit your workflow. 

Also, you can also change the default 'leader key' for tmux as well, ex: Change it from the default 'Ctrl + b' to --> 'Ctrl + a'. This helps if you're used to GNU Screen, etc, since that uses that keybinding by default.

Here's that playlist I was referring to earlier, should help you to learn 'tmux' a bit better:

I'm currently using byobu [1], which is an enhanced wrapper/frontend
for both tmux and gnu screen.

tmux is well-known ... but very good, I agree. I think it is
from the BSD world originally. Nowadays most people use tmux
but some people use screen. But there are several
multiplexers, as always.

In Emacs I think it isn't as common because there/here we have
buffers for everything, including shell work, so the tmux
session and pane typically plays a less prominent role ...

There is a book on tmux BTW:

@book{tmux,
  author     = {Brian P Hogan},
  isbn       = {978-1-93435-696-8},
  publisher  = {Brian P Hogan},
  title      = {tmux: Productive Mouse-Free Development},
  year       = {2012}
}

I didn't do a lot of config but I have one file, and here it
is:

  https://dataswamp.org/~incal/conf/.tmux.conf

Keep it real ...
