Decent Terminal Emulation on Mac OS X? 115

Drawoc Suomynona asks: "After settling into Mac OS X over the last four months, I'm generally impressed. However, due to the sort of development work I do, I spend a great deal of my time in a terminal. Unfortunately for me, decent terminal emulation seems to be one area where Mac OS X is quite lacking. What's your answer to the state of terminal emulation on the Mac?" Drawoc summarizes the currently available offerings and their drawbacks, below.

"Take, for instance, the following options:

  • Apple's Terminal is slow (though performance has been better in 10.2.x), doesn't support xterm mousing, and for some reason refuses to send PgUp/PgDn through to any applications running in the terminal (gah!). Sure, transparency is nice, and with some hacking about (when was the last time you had to force "stty erase"?) you can get decent enough color xterm emulation, but... what's with the lack of PgUp/PgDn?
  • The open source iTerm is slightly better, but, it's awfully slow (it grabs as much as 30% of the CPU per terminal instance... now imagine a full-screen vim session at 1600x1200... it's utterly unusable). It also neglects to support xterm mouse reporting.
  • The closed source GLTerm ($10) is probably the best of the three "native" options, from a certain perspective. It manages to sidestep the CPU usage/UI responsiveness issue by rendering the entire terminal using OpenGL (yes, the characters are actually textures on GL primatives). It supports xterm mouse reporting. However, font choices are limited, it works only on supported video cards, and it has a very annoying "fuzzy text bug" if you set your terminal to the wrong size.
  • Finally, you've got xterm :) But, it means you need to run X11 (either XDarwin or Apple's X11) and it doesn't integrate as nicely into the OS X workflow..."
So, is there a secret terminal port from NeXTSTEP lurking in the pocket of some intrepid young hacker, who is, as I write this, poised to lead us to salvation?"

      Look into a UNIX utility called screen. I'm not sure if it's included in OS X, but I use it all the time on Debian and OpenBSD and it's wonderful. You can detatch and reattach sessions, so if Terminal crashes, you can just open another one and run screen -R to pick up where you were. It also supports creating multiple windows in the same terminal, and a whole ton of other features that I haven't even tried yet. I've even used it to start a process locally, then ssh in later and automagiclly take control of the process. It should compile without problems on OS X; there might even be binaries available.

      if the terminal app crashes you lose ALL of your terminals!

      I hit this one a LOT. It's a real annoyance.

      Why, I hear you ask? Well... [fx: takes a deep breath] Most of my text files use the Windows Latin-1 encoding (the same as the default ISO Latin-1, but with curly quotes and other useful control characters in an otherwise-unused range). No problem for the Terminal: you can set the character encoding in Window Settings->Display.

      I use the vi editor; you can tell it the character encoding through the $LC_CTYPE environment variable. The only problem is that although Mac OS X comes with several character encodings (in /usr/share/locale), it doesn't come with one for Windows Latin-1 (aka CP1252). So I've created my own (with the mklocale(1) command. I've even submitted the result to Apple in the hope that they might include it with future versions... though I haven't heard anything back.)

      So, with both Terminal and vi set to use the right encoding, it all works: I can see all the extended characters, and edit them in the usual way. EXCEPT that there's some bug or incompatibility lurking there. Every so often, when I'm editing in vi, the Terminal will suddenly quit for no reason. It happens often enough to be fairly sure that it's related to the extended characters and to vi - it's never happened when editing plain 7-bit ASCII files, nor when using extended characters in the shell. I suspect it may be related to extended characters appearing at the extreme right or bottom of the screen, and/or to the VTwhatever formatting codes (which I don't really understand).

      Since I do a lot of editing, I find Terminal crashes several times a day... MOST annoying. So, if anyone has any idea what might be causing these crashes, or can shed any light on this stuff, please let me know!

      (BTW, since Mac OS X 10.2.5, vi has stopped taking any notice of $LC_CTYPE! I'm not certain why, or what's changed, but it's easy to download the vi source from Apple's Darwin page, and recompile with a one-line fix I found to restore that functionality. I've raised a bug report with Apple about this, but - again - haven't heard anything yet.)

      • quit using vi :)

        seriously, you can get vim (Vi IMproved) from fink, darwinports, or gentoo soon (console & X11 version).

        even better, you can get gvim with a carbon gui at

        this site [swdev.org]

        I primarily use the carbon gvim now in OS X. I only use my fink version when I log in remotely to my OS X machine. Once you try vim, you will shudder at the memory of using 'vanilla' vi

        • I tried using vim (v6.1), but I can't get that to show the Windows Latin-1 extended characters at all! (Yes, I could probably hack into it, but I really can't be bothered, not when various other things about it just annoy me - nothing major, but lots of minor differences all add up.)

          Besides, the problem may well be somewhere like the curses library or the terminal driver rather than in vi itself, in which case vim would then suffer from the same problems.

          • if the problem is curses, that wouldn't apply to gvim (X11) or gvim (carbon) since they don't run in the terminal, they have their own separate window.

            also, vim has a vi compatibility mode. if one of the gui versions works with your character set, you can try 'set compatible' in your ~/.vimrc file.

            I can't live without the multiple undo levels, the much more convenient cut buffer handling, the syntax-directed coloring, splitting the buffer (horizontally or vertically) to show more than one file at a time

            • True. And it does look nice. But remember that the Apple-supplied vi is really nvi, which already has multiple undo levels* and several other nice features. Buffer splitting isn't something I'd use much; whereas supporting CP1252 is a showstopper for me.

              I guess what I really want is an editor with the power and flexibility of vi (navigation, REs, editing commands), but with full support for character encodings and proportional fonts. (Yes, for code too. I know, I know, I can

    Unfortunately, the tabbed interface iTerm has is so compelling to me that I can't switch back to the stock Terminal.app.

    I agree with the original poster about X. Running Gnome term or any other X-based terminals isn't great, since X doesn't quite integrate seamlessly with Aqua.

    As a heavy user of cygwin on a slow desktop PC, I was delighted to see that someone had ported rxvt [rxvt.org] to that environment. It gives quite a lot of the top-class features of xterm, and little of the unnecessary bells, whistles and complete brass, woodwind and percussion sections that come with xterm.
    However, for your purposes, it can also be installed and used without X11, as in the case of the cygwin environment.
    What's best about rxvt is it supports what you describe as "xterm mousing". This feature alone is why I always stuck with xterm until I discovered rxvt. That rxvt has it is why I won't use any other terminal emulator for a long time into the future.

    Mind you, none of this is useful if rxvt hasn't been ported to Mac OS X, but it certainly is worth checking to see if it is.

    Having the latest Eterm running under Apple's X11 is nice, though I still haven't been able to get it to link with imlib2 successfully (note: I am incompetent at this stuff, YMMV) The only porting really required is to change the typedef for socklen_t to int, or include the appropriate header file (sys/socket.h?).

    iTerm has given me the one thing that I've found seriously lacking in Terminal.app: configuration of what colors are used to display ANSI "colors". No more screaming yellow or illegible dark blue for me, thanks.

    Unfortunately, iTerm does have a few limitations and bugs:

    - while the xterm-experienced will like PgUp/PgDown going straight through, and using shift for local scrolling, I'd really like to see this togglable.

    - no Home/End functionality, with our without shift.

    - no local Find.

    - it "helpfully" doesn't include whitespace when copying out of its windows. Actually, I did want that linefeed, thanks.

    - periodically decides it wants to just sit and suck all my cpu until I kill it.

    - font settings don't stick between launches.

    I've also found that Terminal.app's split-window function is surprisingly useful. And unique, in my experience.
    • Terminal.app's split-window function? I've never seen that function in Terminal. Could you elaborate.
      • click the little widget on the right hand side, just above the scrollbar and below the title bar, and voila.
        • Ah. I operate without a scrollback buffer so I don't get the scrollbar ergo I don't get the little widget. I just tried it and it split the screen but the behaviour was very odd. It doesn't appear to be two seperate terminal windows but a way to view things that have already scrolled off the screen. Strange. At any rate, Terminal.app still isn't the greatest but for now, it's the one I like most. I just wish Apple would improve the speed and add some tabs. That would be just great.
          • Yeah, that function of Terminal is odd, and hard to give a description or name, but surprisingly handy. It allows you to simultaneously see and interact with two arbitrary segments of scrollback within a single window.

            This facilitates doing a variant on a long series of steps you did a while earlier, comparing previous output of an operation to current output, or just reading deep scrollback without missing new data. It's not a life-changing feature, but it is regularly useful.
          • You don't really need tabs: there's a nice keybinding for switching between terminals. Try cmd-left and cmd-right to go the previous/next terminal window. I was delighted when I found that one out :)
            • Or command-~, like *all* mac os x apps, it will switch between windows.

              Why have a differnet keybinding for the same logical action?
              • Command-(n) is also nice, where (n) is a number from 1 to 9. Each Terminal window is assigned a unique (single-digit) number when spawned. Since my Terminals tend to be long-running, I can count on a session being Command-1 for a build, Command-2 for a man page or tests and Command-3 for something else.

                File -> Set Title... and check "Command Key" gives you the visual cue for each window.

                This also seems to be a common design for those Mac apps that have more than one "similar" document window.

            • I use an iBook so screen real estate and memory are at a premium. I would prfer to have a single window with tabs rather than multiple windows. I had never seen tabs in action until Apple added them to Safari and now I can't live without them. What I like best is that you can see what's open in each tab without having to look to the Window menu. Screen is great but I'm often connected to multiple systems with screen running remotely and I hate having to use nested ctrl-a a sequences. As long as I'm babbling

    The TERM environment settings for Terminal.app make a big difference in its behaviour. Normally with Terminal it's useful to have the TERM environment variable be 'xterm-color'. This will enable lots of interesting things, amongst them ANSI color. But, as described, this has it's drawbacks, including the fact that scrollback doesn't work as expected. Sometimes it's useful to launch any apps that need that functionality prefixed with 'TERM=vt100'. I run screen this way( 'TERM=vt100 screen') and it works much better as a result.

However it also supports VT52 mode, double-sized text and most XTerm sequences, and has VT220-specific features like floating keypad windows.

    I should know, because I am writing its (open-source) code! :)
    • Hi,

      how can store the setting of all the toolbars? I just want to have the plain terminal without anything around, the settings are only for the current window and I do not see any option to disable them forever.

      Hmm, as with all others there is no mouse support for stuff like w3m or at least I did not get it running over ssh to a linux box.

      Why is it building the scripts menu each time I run mactelnet? The font list caching is nice...

      I guess I will get the source later for kicking out the toolbars...

      • Look in Preferences, General, Options for the checkbox to initially hide toolbars. This will be improved in the future.

        The rebuild is done each time in case you have new scripts installed. One day I will improve that to cache the modification date or something so that it will not even display the progress bar.
