Ask Slashdot: Where Are the Modern Terminal Emulators? 286

Slashdot reader SoftwareArtist writes: Terminal emulators have barely changed in 30 years. They're still just scrolling windows of unstructured text. Why is there so little innovation in an application we use every day?

There are so many ways they could be modernized to help us be more productive. For example:

- If I type ls to show a directory listing, I should be able to right-click on a filename and get a list of operations to perform on that file, just like a file browser.

- If I start to type a filename and press tab twice, it shouldn't just print a list of possible completions. It should provide a popup to select the one I want.

- Why can't I cat an image file and see the image right in the terminal window?


Are there any modern terminals that update this important tool for the 21st century? And if not, what prevents them?

      So why not just use a file browser? They will filter out files based on partial name, show you a list of options when you right-click on them, do the default option when you left-click on them, and you can even see the images all laid out when you open a directory.

      Plus of course drag-and-drop into another program.

      So why not just use a file browser?

      • Because you're probably doing other operations at the same time that file browsers don't support, and you don't want to have to switch applications in the middle of your workflow.

        As a KDE user, I can give you another reason: because Dolphin will take an hour to copy or delete files that process in milliseconds in the terminal.

        • So don't use dolphin. and be very careful using shell expansion in a command that might end up being recursive ... bad things tend to happen.

          I gave answers for the complaints in the original post.

          As for "switching applications in the middle of your workflow" - stop working with a shitty tiny laptop screen with overlapping windows. There's no reason you can't have multiple screens, with only 1 or 2 applications open in each one, and easily switch between them.

The user can then do the things mentioned. Let the user set a preference that when 'ls' is received it, agai

      And in particular, the terminal emulator is separate from the shell that you having running inside it. To add any of the suggested features you need to add support to the terminal emulator and to bash, tcsh, and zsh. And you're not going to get those changes into upstream, so you're using incompatible forks.

        This. There are graphical terminals (X-windows, RDP, Citrix), and text based terminals (VT100, Telnet, etc). Original submitter should choose the one that works for him.

        If he simply wants menus in his text based shell, there is always Curses/Ncurses. If he wants to use a mouse, might as well go full graphical. A CLI with mouse support sounds like something approximately nobody but them wants.

    Essentially what you want is not a terminal emulator, but a GUI that has a command line. Those exist in many areas for specialist uses. For example I think AutoCAD comes with one and software like Maxima comes with it in its graphical version.

    Probably the best generic one can be found on Lisp machines as part of their Geneva operating system. I think Symbolics will still sell them to you as a plug-in board for certain Macintosh computers. As far as I know, it can do all the things you mentioned.

    Probably the biggest problem with that is that the concept of a terminal emulator is to display characters. This is something completely different to a browser which deals with complex document structures where a text can also be a link. This is one reason why browsers are so complex and terminal emulators are a lot simpler.

    The terminal emulator is one level too low to be very smart about what the user is doing. It's providing a text window. Interacting with that, you typically run some sort of shell program (e.g., Bash), and then from there you run other programs. In theory, a terminal emulator could be told what shell you're using, and then watch the command stream to sometimes figure out what you're doing, but not always, as if you use some alias for 'ls' instead of typing it directly, it won't know what you did.

    Now I suppose a terminal could determine what process is writing to it, and from that determine what command is outputting, allowing it to do something special with the text. So in the terminal configuration, you would specify filter scripts for various output programs (perhaps with examples for 'find' and 'ls'). These scripts would add special escape codes that would make things clickable to run other scripts.

    There are some simple things that would be nice to do, like make URLs clickable (triggering a script that would open a new browser tab, perhaps), which could be done with regexp matching. I wouldn't be surprised to see comments with names of terminals that can do just that.

  • A terminal EMULATOR does precisely that: it emulates the behavior of a text-only interface. This is because we have an ecosystem of command-line tools designed to work on a text-only interface, often interacting with each other forming pipelines. Any system administrator or DevOps engineer, and most software developers, need to work on a daily basis with command line tools that are intended to run without human interaction: when we write workflows for GitHub Actions, run commands on a remote host via SSH, a

    The short answer, I suspect, is that it doesn't exist because nobody wants it bad enough to write one, and nobody sees a market big enough to pay someone to write one.

    I'm looking at this from a linux user perspective, so I can't speak to Windows or Mac, but probably one of the biggest reasons is philosophical. I use a terminal in order to *avoid* all those gui-based things. If I have a task and want to click on things with my mouse, I'll use an app that does that. I wouldn't double click on the output of an "ls" command because I don't want to reach for a mouse.

    Second, a fair amount of terminal typing involves playing stupid regex tricks or more complex commands or writing simple code. I don't know how you would make that work in a gui without turning it into an IDE, and there are those around..

    So, you tend to find terminal emulators that extra actions and capabilities, but they mostly are pointed at improving readability (e.g. color text and auto-indent) and the ergonomics of typing. There is one emulator in linux that will provide previews of images and such, called Terminology I think, but I've never bothered to use it. Finally, if one is used to a terminal, then the ergonomics of doing what you suggest would take *more* keystrokes than just typing the command. Double-clicking on output and then choosing something from a drop-down would slow me down. Similarly, I almost never type a full filename, since combinations of wildcards and such make it unnecessary. Most of the time, it's just a couple of characters.

    So, I probably wouldn't bother working through the learning curve to use a terminal with gui addons.

Well of course there were earlier iterations like Geoworks (RIP) but you get the point. Seems to me the whole point of a terminal is to deal entirely with text, including the inputs used to make it do things. If you want to save time typing, copy paste from the GUI you seem to resent into the terminal. If you want it to output something other than text, what's wrong with just opening the image

    This is not a disparagement of terminals, because they're either good at certain tasks, or allow simpler development.

    Terminal emulators have barely changed in 30 years. They're still just scrolling windows of unstructured text. Why is there so little innovation in an application we use every day?

    On a highly technical level, modern graphic terminals are meant to emulate the ascii plain text of older devices, which in turn emulate the 80x25 character display, which in turn emulate the 80-column punch card system [ibm.com], and early ASCII tables. Even though terminals are useful, they're still anchored by significant historical design.

    There's been a few attempts to at least break out of the raw text stream - mostly the Curses library in order to give colored text, or to at least allow presentation beyond a simple text stream, but it was still designed for terminals rather than interactive GUIs. Additionally, something like Telnet (a primitive remote console) didn't autodetect the client's display size.

    Now, there's room to make adjustments if the official standard is willing to shed the last remnants of the oldest terminals; perhaps shedding the various ascii control characters that don't seem to be used even in special cases (anyone seen Shift Out or Shift In?), and replace it with new control characters that can help. However, this requires changing a standard and that's extremely slow.

    - If I type ls to show a directory listing, I should be able to right-click on a filename and get a list of operations to perform on that file, just like a file browser.

    So, that would be a rich-text or hypertext terminal. After fiddling with the standard, let's pretend this works, and implementing it isn't too complex.

    The question is how it will work. Let's say I'm on Windows, and using a telnet to a Linux system - how will right-clicking to get the filename help when going across computers? There's no guaranteed file sharing, or it might be blocked for some reason. Maybe the file isn't in a shared folder, such as something in /etc/ or /usr/home/root/

    Your example works fine on local terminals, but not for an SSH into a remote computer.

    - Why can't I cat an image file and see the image right in the terminal window?

    At that point, it's full hypertext. I'd want to be very cautious with that, considering the many ways some webpages can attempt to trick the user into doing something that shouldn't. And since terminals are designed for dealing with admin-type stuff, it can become rather dangerous.

    I'm sure it varies by user, but when I'm typing into a terminal and not just launching some application, I'm usually doing some system configuration stuff so I want a basic low level interface, not something that require a bunch of other things to be working. I also don't want to learn all of the "magic" features some particular terminal emulator may have.

    There may be use cases where complex terminals are useful for things that can't be scripted, but I don't run into them.

    No. If I wanted a file browser, I would have used a file browser. Terminal emulators are used by people who can read and write, not just point and grunt.

    A few years back, I created a set of libs [slides.com] to provide this in Gnome Terminal. Not the most elegant solution but it allowed SVG to be rendered into the terminal and so, once the custom libvte was installed then gnome-terminal would support overlays like a miniview for vim (only requiring a vim plugin), ability to print image files to the terminal, matplotlib graphs for system monitoring, etc. I even had partial tmux multiplexing support and passthrough for SSH.

    Naturally, there was a lot of work to do going forward to make a stable production tool - for example, if a program can write arbitrary images to your terminal it can mislead you in ways a normal console program couldn't, but equally usage/security issues like that were not necessarily _that_ far from what you could already do, and these were not unsolvable problems. Compatibility-wise, anything that could output SVG as text could manage the simple protocol, and I'd client libs for Python so it was a little like ncurses usage (in fact, one example uses ncurses and gasket).

    After a while I realised that the general response was "Nice novelty - shrug" so rather than keeping maintaining or improving a fork of libvte, I stopped. That was 8 years ago - now I still miss my miniview in vim :/

  • The beauty of terminals is that they're just scrolling lines of plain text. Plain text is a kind of universal language.

    if you want a GUI app with a command line, that is a totally different thing. For example Python has Jupiter.
    There's a lot of scope for a 'graphical command line'. Indeed a lot of scope of a text-based interface that isn't a terminal
    (rather a m×n array of character cells that you can address directly). But then, while you're at it, why stick with
    monospace fonts for everything? What about dockable tabs that give you dynamic help on what you're typing in?
    If you dispense with the *nix way entirely, and have a pile of built-in commands, and a powerful modern scripting
    language for writing more, and which wrap the standard *nix commands (together with information for completion
    and help), that would be nice. But again you're talking about a command-line driven GUI app. I'd love to see that,
    but it isn't a replacement for the command line per se. It could, if such an app existed, be readily adapted to make
    a powerful learning environment for the actual text command line. But it's kind of like replacing the 1-liner 'printf("Hello world");'
    with a React app and an Electron runtime to load it.

    The thing with command lines is that, despite their simplicity, you can do a lot with them. And if you're connecting to a
    server in another country via SSH, you get essentially the same Linux environment you have at home.

    1. Because they have to work over a TTY interface, people who can't hear still use serial based TTY terminals to this very day. In infrastructure management we still use literal serial terminals to manage and access pre-boot environments. Servers boot up using serial console redirection.
    2. They are very well established standards that just works, i.g. POSIX, DEC's VT220 with Sixel support[1].
    3. It's extremely scriptable and programmable because the domain and range of the functions are very well defined, i.g. ASCII and UTF text and escape codes.
    4. Once you've mastered the POSIX userland there just no need to rely on anything else, I can write the equivalent of 100 lines of C code with just a single line of POSIX code in a bash shell.
    5. iTerm2 already has most of these bells and whistles, you just have to know the macros and keyboard shortcuts.
    6. KISS

    POSIX honestly is its own programming language once you have master all of the essential verbs and how to correctly setup your tasks for stream processing using shell scripting. I can tell the machine explicitly what I want it to do for me on my behalf autonomously, so for me personally if I had to go back to pointing and clicking that would be a major regressive step backwards, and at that point I would just use Finder in the GUI. There is AppleScript and Automator as well, all four of these things have their place.
