Does anyone really use emacs in terminal?

Does anyone really use emacs in terminal?

[Steven Degutis]

What's the use-case for having the terminal be able to act as an editor?

For me it's rather the other way around, I use the terminal within my
editor (eshell).

Seems like there's no real point in supporting terminal-mode in a text
editor these days.

Remote editing on systems that have SSH but not X11. Android and iOS tablets and phones are pretty common.

It's also pretty nice with something like screen or tmux.

The cool kids do it.

You can find many screencasts of people doing everything in terminal
and proselytising the simplicity and lack of distractions of such a work
flow.  They don't mention the lack of features, and the pitfalls.

As a result a lot of the newbie questions on stackoverflow and here are
"Why dozn't M-return work with me Emacs?" and "How comez when I can't
cut'n'paste from Emacs?".

This is frustratingly detrimental to Emacs adoption because the new user's
initial experience with Emacs is "fixing" it.

There apparently are such use cases.

You may also argue on MSDOS support in Emacs; but of course, even
if we decided to drop this support, someone can still distribute
his fork of Emacs with MSDOS support.

The same with terminal support.

Indeed GUI isn't anything different.  We can also decide to
distribute Emacs with terminal support only, and let someone else
to distribute their GUI fork.

Therefore such argues are pointless.  As long as someone are
maintaining the relevant code, inclusion of the support does more
good than bad.

Re: Does anyone really use emacs in terminal?

[Steven Degutis]

I'm so tired of how Emacs so desperately clings onto the 80s and 90s.

So many of its defaults are idiotic, so many legacy features it tries
to support are just terrible and useless.

I often wish there was a modern emacs clone that dropped all these
legacy features.

Who ever uses a toolbar?
Why don't the scrollbars work like normal?
Why is the undo feature so ridiculous, instead of something more sane
like undo-tree?
Why isn't ido-mode enabled by default, and why doesn't it work on more
completable prompts without a third party plugin?

I use emacs in a terminal all of the time every day.  How else are you
going to edit files while logged into a remote server?

If emacs didn't support the text terminal anymore, something that it
has done since the beginning, then it could hardly be called emacs
anymore could it?  It would then be something different.  Like
gtk-emacs or something.  Which is fine.  But if emacs weren't
available to edit files would you expect we would use vi?  Horrors!

Re: Does anyone really use emacs in terminal?

[Steven Degutis]

Any time I find myself editing files on a remote server, it's because
I stupidly didn't prepare for the task properly and have to fix
something "live". This is never a planned situation, and one I should
really be avoiding rather than catering to. And in those rare times
that I still find myself editing remote files, the server usually only
has vim anyway, which gets the job done. This isn't a legitimate
reason to have terminal support in a text editor that you use on a
daily basis on your local GUI-enabled desktop.

I am so tired of how people take current working tools and modify them
to be something completely different that breaks it for everyone who
was using it.  GNOME 3 is a good recent example but there are others
before it.

If you want to take emacs, or any other tool, and fork it off and go
into a different direction that is great!  I fully support you doing
that.  Emacs has been forked many times already.  That is one of the
awesome things about free(dom) software.  It gives you the ability to
modify and customize it.  If you think emacs is backwards then write
it your way reversed.  Call it "scame" because it wouldn't be emacs.

But don't break the existing emacs users to build that new tool.  Just
build that new tool.  Don't make your gain a loss for others.

"I love you.  You are perfect.  Now change."  I *hate* that!

Then fork it and do your own thing!  But please don't break it for me.

Do it!  The source is there for you.  Or start clean with an empty
directory.  There are no limits.

That's rather the other way you should ask: what's the use case of using
a bitmap _graphic_ screen to edit _text_?

That would be a WYSIWYG word processor, I wouldn't say, but we're far
from it with emacs.

There's a lot of point, on the contrary:  there are a lot of emacing
done thru the internet, and since we don't have yet gigabit fiber
everywhere, and even if we had it, we may not have guaranteed bandwidth
to all those remote servers on which we have to edit configuration
files, or debug server programs, it is much easier to work with a
terminal thru ssh, than with X11 thru ssh (or even worse, thru vnc).


There are also users with special needs that are not fulfilled by GUI,
but who can work much better with a TUI, ie. with a terminal (eg. blind
people).


Now, of course, when I use emacs locally, I prefer to use it with X11
(but notice, without any decoration (I use ratpoison) or any other GUI
element (I compile it with no X toolkit, and I use it with:
    (scroll-bar-mode     -1)
    (menu-bar-mode       -1)
    (tool-bar-mode       -1)
so if you compared a screenshot of emacs with X11 and emacs on a
terminal (with 256 colors), you wouldn't notice any difference).

Only from time to time, when I visualize a PDF or a PNG, would it make a
difference (but then, on a terminal we could also switch to some bitmap
mode, either with a frame buffer on the console, or switching to the
Tek-4041 mode).


Even when connecting from my iPad (with iSSH), it's easier to use emacs
thru ssh in the terminal, than on X11 (which iSSH provides).

I do. I use it mostly over ssh on supercomputers.. no need to forward X11
sessions and all that junk. I would say I never use emacs without the
terminal.

The problem is that you naively assume you can compile things on your
desktop that you can your remote server. For me, that's almost never the
case, as no desktop or laptop has the hardware that a supercomputer has.

Because then my syntax highlighting and color theme has access to some
several million colors, not just 256. This, plus viewing it on a retina

This has nothing to do with emacs, but all to do with lack of knowledge
of said newbies about how terminals and computers work.  Direct them to
the corresponding tutorials.

Or direct them to emacs in GUI (X11, Cocoa, MS-Windows).



Otherwise I wouldn't mind if somebody worked on the terminal protocol,
notably on the keyboard part. (ECMA-048 is rich enough, for terminal
output).

I heard there are some extensions implemented in xterm to forward the
status of more modifiers than just control.  Some standardization and
wide adoption amongst terminal emulators at least (are physical
terminals still produced?) should do the trick.

But look at the bigger picture. There's no need to "emulate terminals"
anymore. The vast majority of computers aren't terminals and don't
have anything to do with real terminals. We're stuck in a circular
backwards-compatibility loop: we need terminal emulators because our
programs rely on them (less, cat, ssh, etc), and we write programs to
work on terminal emulators because that's all we have to run them on.

No, not on my servers.  They never had vi or vim installed.  Not since
1986.  Even before booting the first installation of a system, emacs is
installed on.  Otherwise how can you configure it?

Well, sure, you have to justify the price of a retina display. Now
you're realizing that you're spending the day working with text, not

Yes, any clone is a fork, but only the Privileged Few can understand
emacs' source code enough to do anything decent with it.

You can't seriously be suggesting that undo within a text editor is
not a useful feature?

I agree, ido-mode is unbearable in its default state. But with
ido-vertical-mode it's pretty great:

That said, instead of complaining about terminal UI in emacs, you could
consider developing a CoreAnimation UI for emacs.  If you can display 
emacs windows nicer than SublimeText or Light Table, everybody'll be
happy.  But that'll just be yet another display engine for emacs.  This
won't change fundamentally the fact that it works mostly with text.

I think we'd drop terminal support if there was a good case *for* it.
But as it currently stands, before Emacs could benefit from dropping
support for terminal mode, we'd need a fair bit of change I think.

Admittedly, I have internalized most of the problems with terminal mode,
but I have a hard time thinking of cases where "oh, but it needs to also
work in terminal mode" was a significant impediment.

The only place that comes to mind is for choosing key bindings, but
even there, many other constraints (e.g. backward compatibility so as
not to anger all existing users; and being accessible for users of many
different keyboard layouts) tend to bring in the same problems anyway.

a) ido-vertical-mode wastes screen estate (blank space to the right). I

You cannot see the million differences. (And I doubt whether the monitors can really produce that many different colours in the real world.) *Trained* human eyes can differentiate between 128 colour tones and 130 saturation values. In the blue spectrum these eyes can percept 16 levels of light intensity, in the yellow spectrum it's 26 different levels. This makes up for 380,000 different perceptible colours. 16-bit colours are quite right for average computer users with colour monitors.

I'd wish GNU Emacs could read my mind so I wouldn't have to type typos!


Is it possible to invent the million names for the millions of theoretical colours? How many years would be needed? Would it be OK to use rather colour blind men for this job? Or should we aspire the maximum and engage sensitive women?

"The" terminal?  There are several.  I run Emacs in a Linux virtual
terminal, unless forced to use a GUI setup - e.g. for testing elisp.

Why?  Because I want to run Emacs without distractions, without window
borders, without the mouse, without faffing around with fonts, and with my
Emacs frame filling the _whole_ screen.  As somebody else said, why use a
graphic environment for manipulating pure text?  A GUI is a general
unspecific mush, whereas a TUI is optimised for text.

Setting up Emacs on the virtual terminal is some work, agreed; you have
to extend the rather sparse keyboard layouts, and then teach Emacs how to
understand the new keyboard codes; working with several frames can be
awkward, so I wrote a little utility for key <Fn> to switch to frame n.
But the effort is worth it.  To me, being able to run Emacs on a terminal
is one of its chief attractions.

You can do that on a terminal too.  :-)

Well, thanks very much!  I believe that Richard Stallman uses Emacs on a
virtual terminal.

It is sometimes useful to have an editor available during installation of
a GUI, before that GUI is usable.

Are you suggesting you're willing to put in the work to remove terminal
support from Emacs?  It'd be a lot of work.  What would be the point?

Exactly. And if anyone is seriously proposing to remove terminal support,
could they also implement all of the necessary ATK interfaces to enable my
braille display to be used with Emacs under X11 and GTK? It works wonderfully
at the console and also over ssh connections, thanks to the terminal display
code in Emacs, removal of which would be a major regression for my use cases.

I should mention that I use Emacspeak for speech output and highly recommend
it; Emacspeak can run equally well in a terminal or under X, but for braille
access (using a refreshable braille device) Emacs really must be run in a
terminal session.

Occasionally I need to work on a remote server which doesn't have X 
running and have to do extensive editing, not trivial enough to use vi. 
  So, yes, in those instances it's nice not to have to learn a new 
editor-- which would be the only alternative.

Also, I've run emacs in batch mode to extensively edit thousands of 
files non-interactively all "at once", something which would have taxed 
my sed, awk, and grep skills and required a much longer time to develop 
than it did using emacs.

Emacs isn't simply an editor in the sense that Word is an editor. 
Stallman, in fact, prefers the term "text processor" to describe emacs, 
and as the people above indicate, it's a very extensible one at that.

As for the usage patterns, I should mention that it occurs often enough
that I use both terminal frames and X11 frames.

(And if Cocoa emacs was able to do it, I would also use X11 or terminal
frames at the same time with a Cocoa window).

Since I reboot emacs only when I need to reboot the underlying kernel, I
connect to my emacs instances thru any kind of interface.  I have on my
desktop a MacOSX, a Linux and a MS-Windows-7 system, and I may also
connect to it remotely.  Therefore I may want to make frames from any of
those interfaces to the same emacs instance.

Then why bother, if you can have a full-screen Emacs without scroll bar,
menu bar, tool bar, window borders etc. but *with* all the "ease" of
running Emacs under X?

Not that I'd be in favour of removing support for using Emacs in a
(virtual) terminal, though. I use it myself sometimes for testing Elisp
code in a VM (my 5yo computer would grind to a halt if I'd run X in a VM...)

I use "sudo emacs -nw <filename>" in terminal to edit configuration

This runs emacs with su power, which is not so good. I suggest using
$ sudoedit <filename>
with the (EDITOR or) VISUAL environment variable set
to "emacsclient" (or to "emacsclient -a=" or "emacsclient -a= -t", or
"emacs" if you really prefer a new emacs session to be started.).

(And, going back to the subject, I also use emacs over ssh regularly
together with emacsclient, and don't have an internet connection good
enough to create X frames over ssh.)

Yes.  However, you must be conscious of the theorical possibility of
emacs lisp viruses thru file and directory local variables.

If you find-file in a directory where a malicious user has written a
.dir-locals.el file, he could theorically take advantage of it to root
you.  Of course, normally emacs ask permission to evaluate a form, or to
set any variable he doesn't know to be safe.  But if you type y or !
carelessly, you can be hosed.

But emacs will always ask you if it should proceed due to that issue.
It will never do it automatically.  It isn't intrinsically insecure.

But only if you approve using the local setting.  And you would need
to be exposed to hostile user attack in order to trigger it.

If it is your laptop with you as the only user that is unlikely and
answer yes without thinking probably won't hurt you.  You can think
less.  You are more safe on your own machine where only you work.

If you are an admin of a university system with clever kids poking at

Yes, but then, I *know* I will do something harmful by using a different
editor than the one I'm used to when occasionnaly editing as root, hence
my relentless destruction of any other editor than emacs on systems I
install, even before the first boot.


No, the only real risk with emacs, is that it's so agreable to use, that
you may forgot you're logged as root.   For this, I have:

    (when (= (user-uid) 0)
     (set-background-color "black")
     (set-foreground-color "red"))

in my .emacs files…

Well, that depends how paranoid you are.  It used to be intrinsically
insecure (only prompting the user for things known to be dicey) and has
been improved over the years (always prompting unless told that it's
safe), but there are so many variables marked as "safe" that might be
used in unexpected ways by so many packages that "intrinsically secure"
sounds naive.

More specifically, I'd be *very* surprised if there aren't any "big

I didn't say "intrinsically secure".  I said, "It isn't intrinsically INsecure."
Which isn't the same thing.  A couple of quotes come to mind.

Show me the bug report.  Unless there is a bug report on *something*,
anything, then I call shenanigans and say it is nothing but spreading
FUD (fear, uncertainty, doubt).  Because just using the computer is a
security hole.

don't have anything against Zile.)

Sure, you can forget you're root, (in all cases), but dired as root is
maybe more than just a nice to have. For instance, it makes it easier
to browse the system logfiles, etc. I can't say that I'd never use
Emacs as root - it is simply too useful, and the trade-off of potential
security risk versus utility seems to me to be one that I'm willing to
make.

I have this in my (minimal) init file for Emacs root sessions, which is
quite nice since it keeps the e.g. black background and wheat foreground
colors and only adds a red header line at the top of the buffer. I
copied it from somewhere, probably Fabrice Niessen's .emacs, but I'm not
sure about it.

GNU Emacs is a bit ore than just a plain editor. It can perform a lot more than vi, nano, pico etc. Therefore its use is more dangerous, at least in theory.

I have similar preferences, but instead of running Emacs as root, I use
tramp/su (or sudo on Ubuntu machines).  I am not an expert about these
issues, but I imagine that it is safer than running Emacs as root.

On my desktop I use emacs within X window, even if I've disabled
almost any toolbar and menubar and don't use the mouse at all.
However, when connected to a remote server via SSH, being able to run
emacs is a killing feature to me.
Moreover, what I found very interesting to do is to start emacs on the
remote machine and live within (i.e., use eshell for other tasks).

I'm not sure what you mean "visit remote sites"? I do that with Vim all the
time.

Vim has an interactive calendar extension

"Norton Commander,"

That's an extension that could be done in Vim. It does seem like Vim has an
extension for that.

So, your argument boils down to "There are some emacs *extensions* I like
that Vim may or may not have exactly", not that Vim can't do them (they
both allow for programmable extensions, after all)

That's not functionality, though. That's usability. If your argument

Emacs doesn't really run Vim.. it has Viper mode, but it's not nearly Vim.

Apart from those lisp-family program modes, I like emacs better since
there are more elaborate configurations for me, directory local
variables for instance, which makes emacs a more modern IDE.

Emacs also has more powerful buffer handling features than Vim, although
Vim has better built-in Window and Tab operations.

There is a huge difference among "not 100% vim yet" (vim emulation on
Emacs) with "the most simple features forever" (Emacs emulation on Vim)

And now I wonder why I'm arguing on yet another stupid editor flamewar,

Emacs+vimpulse and enjoying the best of both worlds.

Emacs mode on vim is not just basic features.

The point is: the author (or anyone else) cannot accurately defend the

The information benefited Emacs over Vim, so the original author
deserves praise on this mailing list, not being the accuracy of the

To be correct: I use vi/vim for simple file editing and I use GNU Emacs for some things. Not knowing that vim has so many extensions and coming from vi and being used to used I never had the idea something else than a very good editor. So it's pure ignorance that led to my statement, and I have to commit that it's theoretically possible (in theory, because I never have used such a pimped up vi or vim) that GNU Emacs and vi/vim are dangerous because a super-user can make mistakes when using them which can damage the system. OK?

From the Emacs manual:
   "Visiting" a file means reading its contents into an Emacs buffer so
   you can edit them.  Emacs makes a new buffer for each file that you
   visit.

In Emacs parlance, "visiting" means loading the contents of a file into
a buffer for some purpose (reading, editing, processing, whatever.)

On this mailing list, saying that Emacs can visit a file on a remote
machine is more precise than saying that it can edit that same file.

TRAMP is much more than visiting remote files. It is a framework for
working with a local Emacs instance on a remote machine. For example:
with your local Emacs visit a remote source file, then compile it and
run a gdb session as you would do if it were a local file.

Re: Does anyone really use emacs in terminal?

[Jai Dayal]

Point taken. The manual does indeed define visit.

However Vim offers the exact same functionality.

Not wishing to add to the flames here but genuinely ask a question…

As a teacher of programming, I like to allow students to be free about
things that are distant from programming.
Also by default I use emacs.

Now as for program editing I expect that vim has the mode-
functionality that emacs has.
I am specifically interested in inferior buffers ie derivatives of
comint mode:

Is it possible to run the python interpreter or the haskell
interpreter under vi?
Last I looked it was not.

In case this seems to add to the flames, here's my recent mooc course
offering on haskell+python:
https://moocfellowship.org/submissions/the-dance-of-functional-programming-languaging-with-haskell-and-python
wherein I say that I use emacs but participants can use what they
like.

Re: comint outside emacs (was Does anyone really use emacs in terminal?)

[Jai Dayal]

Vim has a python interpreter.. I think even natively at this point. Vim
also has the Superior Haskell Interaction Mode (SHIM) extension.

The point of Vim and Emacs is that they are extendable. You can get them to
do arbitrary things. There isn't one thing that emacs does inherently that
is impossible to do with Vim, and visa-vera. That's the point I'm trying to
get at.

Pish-posh!  Can Vim "read[ a file's] contents into an Emacs buffer"?  I
think NOT.

This thread should be retitled "Does anyone really use Vim?". I can't see
any reason to support Vim on a modern Emacs-based system, and I purpose
that everyone henceforth cease to put any effort into supporting it. :-)

I was joking, I was not meaning the vim-like mode, just that Emacs is
so powerful that you can run a shell, a directory browser, a database

Well, this is a GNU Emacs related list. Shouldn't it be enough to know the basics of writing and reading, a bit of GNU Emacs, and having a problem to be solved? Best of course when this problem is also GNU Emacs related!

Basics of what?  Basics of vim, on an emacs list?
You are easily shocked, and you've already demonstrated that you are
eager to be offended. 
Since you know the basics of vim; can vim do Calculus?

If one does not know the basics of vim then one should not make such strong

Cool; I didn't know that.  How does vim do it?
Honest question: emacs can do
 M-: (calc-eval "integ(x^2*exp(x),x)")
to get
 "x^2 exp(x) + 2 exp(x) - 2 x exp(x)"
How does vim do that?

I understand that you did a simple google search and couldn't find what you
were looking for (vim in calculus actually means something else), so if
you're not willing to do a little extra work and expect me to prove the
most basic trivial things, I'm going to ask you to put something on the

mailing list again.  deal?

You understand wrong.  I use Calc a lot in Emacs.
But then you aren't really trying to understand anything; you are merely
throwing a hissy fit.

So can vim integrate x^2*e^x?

I expect you to prove that vim can do integrals; no problem for you,
since it is basic and trivial.  I honestly would be interested in vim
doing that so I could play around with it.  I really hope it can, but
your ill-informed tantrum gives me the impression that it can't.

We were talking about vim, not plugins.  Can vim do it or not?
If so, show me how to get vim to do it.  I have vim installed on my
computer; that's all I need, right?  How to I get it to do an integral?
I showed you how to get emacs to do it, now your turn.

This is an unreasonable request. Jay put some amount of effort to find
and write down an example of something that would be supposedly hard to
do in Vim.

If you're unwilling to reciprocate that effort by giving an example of
doing that in Vim, maybe *you* should stop posting here instead.

Being extensible is part of vim. I guess following your logic, all tramp
functionality is irrelevant because it's an extension! You either take the
bet or you don't.  You made the ignorant claim that Vim couldn't do it, not

Why are you being an idiot?

Why should anyone leave this list on your say so.
If you don't know the answer admit it.

I did some simple google searches and found out vim has commands for add
and subtract.  The material I found said if you want to do something
more complicated invoke bc.

I know next to nothing about vim, but I'm always willing to learn.

Believe it or not, the people that post here are here to share

Vi has an interface to shell level: :!. This way you can use expr, bc, or dc to calculate something for vi – or use a GNU Emacs script for something less comprehensible…

A bit different is :!emacs -nw <RET> – now you are in GNU Emacs, in terminal, as the subject announces, and can forget that you were in vi before and now are not that limited. You can even files on some remote host! No plugin necessary.

However this is inconvenient since Vim just forked a new shell
process. Now and then I forget whether the shell's parent process is Vim.

He reason why it's inconvenient, is because once you fork a child
process, it cannot modify the data structure in the parent process
anymore.  So ok, you can perhaps calculate, or do calculus (seems
somebody doesn't know the difference), but you cannot have those process
modify the data in the vim buffers, or in vim memory.

Sure, perhaps you can also have a command or a script in vim to load
some file modified by those child processes, but that's the point:
there's no calculus program implemented in vim, like there are
implemented in emacs.  Or spreadsheets, or web browsers, or email
readers, or games, etc.

Ah, something to search for that might yield results.

Searching for "vim games", I found this:

http://www.vim.org/scripts/script.php?script_id=172

Downloading and looking at tetris.vim I see that vim has some kind of
command language, with functions, buffer access, arithmetic:

fu! s:Sort()
 wh line('.')>1&&matchstr(getline(line('.')-1),'\d\+$')<s:score|move -2|endw
 let s:pos=line('.')
 g/^$/d
 11,$d _
 redr
endf


I'd don't know if it approaches the power of Emacs Lisp, but there
is enough there for games.

Re: Does anyone really use emacs in terminal?

The sheer ignorance with how Vim works and what you can do with it is
astounding! It's as if all of you are stuck in the 90's with Vim
technology. Amazing that such a (undeserving-ly) pedantic group could be so
wrong about such trivial issues! Who can even trust your emacs advice?
Certainly, it's a small group of dilettantes here, each feeding off of each
other.

You did not know this already? I stated that Vim has a language of its own
already. If you don't even know Vim basics, you shouldn't comment on Vim.

A bad day in () is better than a good day in {}.

Wow, you're so smart, I don't feel I'm qualified to read your posts.

So, welcome to my kill file.

You don't need to email people when you reply to posts either but
go for it if you like.  You won't get past my mail filters for long.

Still don't know how to post and you certainly don't know how to carry
on a civilized discussion.

This argument is tiresome. Please carry on using vim, it is good
software. There is no need to subscribe to an Emacs list in order to
badmouth the world, and it doesn't impress anyone. 

Yours astoundingly trivially dilettantly sheerly ignorantly pedantically,

I would really, really like to see those comics, and googling for "xkcd
excessive security", "xkcd root security", and "xkcd root editor", has
so far yielded no results that look like the comics you describe.

So... a URL would be nice.
