Acme for Windows 176

jacoplane writes "You may remember Rob Pike from his Slashdot interview. Since his interview, his two-dimensional text editors have experienced many improvements and ports including license improvements. A port to Inferno has been around for awhile. Recently a standalone version has been made for Windows based on the Inferno port. Linux users are in luck as the native port is now legally distributable."

      Acme is a text editor and shell from the Plan 9 operating system, designed and implemented by Rob Pike. It can use the sam command language. The design of the interface was influenced by Oberon. It is different from other editing environments in that it acts as a 9P server. A distinctive element of the interface is mouse chording.

        Holy synchronicity Batman.

        I just installed the Inferno virtual machine on my Windows box last night because I didn't want to gunk up my Linux and BSD boxes. Plan9 is a sort of Unix the Next Generation, to continue the Star Trek motif. Sam - dunno, haven't got that deeply into it yet, but I gather it's 'sed, the Next Generation' - an editing command set. Oberon (again with the odd synchronicity, as I installed Oberon on my 486 before it died back when) is basically an academic operating system in which everything on the screen was both a display of information and a command interface. 9P seems to be a sort of protocol for communication that relies on the "everything's a file" thing being carried to its ultimate conclusion. Plan9 is kind of conceived as a distributed system in which there's no real distinction between 'local' and 'remote' because *everything* can be mounted and accessed from wherever. Mouse chording is simply a really annoying mechanism whereby you might hold a mouse button while pressing a key. A middle-click, hold, keystroke, and release, is distinct from a middle-click.

        As far as the editor itself, Pike compares to Emacs in the sense that it's a shell, file manager, window manager and editor (and more) all rolled into one. It's also kind of like running vim with 'Sexplore', only - again - much more thoroughgoing. Except he makes the distinction that Emacs is bound to the 'teletype' concept and era. Plan9 is heavily GUI-oriented and mouse based. However, it's GUI in the sense of windowed text and clickability, not in the sense of pretty icons. It's more like every text object is a sort of icon. But there's no 'pictographic' icon that doesn't *say* anything.

        So, yeah - distributed networked next-generation GUI mouse Unix. Sort of. And the editor is an all-in-one interface.

        Unfortunately, Plan9 is actually nothing new. It's like Unix guys seeing a mouse and saying 'Oooh, look what Zog do' and going overboard, while retaining a kind of X11R4 look'n'feel. And, being a vim user and keyboard-centric and whatnot, myself, I find it interesting in a sort of theoretical sense, but not anything genuinely usable or even the right direction to go.

        *My* question is, what does this Windows editor port do that I didn't do last night by just installing Inferno? It was a simple thing to do and gives me rio, acme, and so on and so forth. Also, Plan9 from User Space has been available to Linux and BSD users for quite awhile, AFAIK.

        Sorry if this is a bit breathless and incoherent, but hopefully more detailed than the technobabble writeup. And, as I say, it's still pretty new to me. That's just my rough perception of things.

  • Not only did I have to dig to understand what the story was about, I'm still not entirely sure.

    So, a text editor existed for a very small niche operating system. There already were unofficial ports if you really wanted it. After reading the Wiki page, I'm not entirely sure what makes this text editor special.

    That's all we need is another text editor to argue over.

      Of course anyone who fits in that category already uses it,
    • Basically the idea behind Acme is that it's a GUI editor extensible through shell scripts (IOW extensible thru arbitrary languages). Also any text file can modify the UI, since selecting text and pressing the correct mouse button will execute it as an editor command (or shell script). So for instance you have your .c source open in one window, and another text file open with
      make all
      make test
      make debug
      etc. and you highlight make debug and middle click(I don't remember exactly which button do what) for instance and it will run, making the debug build. It's neat, I never reached the point where I used it as a regular editor though.

          In acme *all* text is a potential command. You middle click and it executes the selection you clicked on (expanding if the "selection" was nothing - ie. if you click a on anywhere on the word make it runs the make command), you can chord to select a region and execute it in one go.

          Of course that means that anytime the text "rm -rf $HOME" appears in a document if you are stupid enough to select and middle click it bad things will happen. Of course the target audience knows better.

          Because everything is editable and executable text you end up doing things like typing the command you can't quite remember the arguments for (find for example), selecting it, chording on the word man somewhere, editing the example text in the displayed man page to be the command you want and then chording it to run that command. Then of course you right click the output of that find command to open the file you were looking for.

    I just don't get the idea of a text editor that relies heavily on the mouse. Keyboard shortcuts seem like a much better idea, since your hands are already on the keyboard when you type. Plus, I find it difficult to quickly click on text with the mouse, since it consists of a bunch of tiny little rows and letters. I tried Sam (another mouse-centric text editor) for a while, and while I thought mouse chording was a really neat idea (one I'd like to see applied more often, although it's not really possible with my touchpad), I never did get to like mouse-based text selection. Does anyone who has got the hang of it want to enlighten me? Whenever I click on text I end up way off, but in the general area, and have to slowly move in on it. Do you get much more precise with practice?

    What's amazing about Plan 9 is the kernel, the file system, and the overall design.

    The user land utilities, GUI, and GUI applications are applications only a mother could love; porting them to another platform seems pretty pointless. Note that the ideas behind acme really aren't all that original--they're derived from the equally unsuccessful Oberon interactive environment.

    Putting a Linux userland on top of a Plan 9 kernel or implementing Plan 9 kernel features in Linux (either in the kernel or in userland) would seem useful to me, but porting the Plan 9 GUI?

    This is quite simply the hardest software to pick up and figure out I have EVER encountered -- and I'm a pretty advanced user of vim _and_ developer studio. I can honestly say that in 20 minutes of playing around I had not yet established what the application was for.

    Right click on the help link, 'acme(1)' and a window comes up called "/+ Error Del Snarf | Look". Hmm, I'd like to get rid of that. Click on the little box in the corner of the window. The window gets bigger -- not really big, just a _bit_ bigger! Ok, try right clicking on the little box. Now the window is really big! Further right clicks do nothing, but now a _left_ click makes it smaller again and I can see the window I started with, which is now only 1 line high. Try to drag the window divider -- no effect. Left click 'Del', right click 'del', double click on the window divider -- you can make it change size a bit but you can't close it.

    Restart application and this time remember to _not_ click on the help link. Try to select text with middle mouse button because apparrently that 'executes' it in some way. Incomprehensible, uncloseable window reappears -- but THIS time it has a long list of lines starting with a # character in it! How to make it go away... maybe click left AND right buttons on the title bar? Er... I have now pasted some text into the title bar of the window. I edit it to say 'Del Snarf' again -- but something seems to have broken now. Better restart.

    And so it goes.

    Brilliant! I'm not actually going to try and use this ever again (because it's pre-alpha, it doesn't seem to do anything vim doesn't, and it's too mouse-driven), but it is one of my favorite pieces of software anyway because at least it's not just unix/java/lisp/MSVC 4.0 redone. It's something totally, utterly different.

    And it is sooooooo haaaaaard to uuuuuuse! Ah, I love it, but I love it in an 'I am going to delete you now' kind of way!

      • I did RTFM, or at least RTFP -- the paper on Acme's design. And when TFP cheerfully described how Acme doesn't have an internal concept of global search and replace but rather relegates those to tool commands that one pipes together, I was certainly impressed. Just, you know, not in a positive way.

        Okay, that's not quite fair. From a design standpoint I think Acme is brilliant and I'll probably look at it again in more detail (I used it a few years ago, but briefly). From a practical standpoint, nothing I've
        • It's hard to see a serious advantage given us by replacing our ^S (or ^XS or Command-S or even :w) with a middle-click on the word "Put"

          From a user interface standpoint, one obvious advantage is that of affordance [wikipedia.org]. Any text in acme affords the command of that name. Command key combinations are hidden out of sight - "Put" is visible and evident, as are "Undo", "Redo", etc, etc.

          And when TFP cheerfully described how Acme doesn't have an internal concept of global search and replace but rather relegates th

          • I suppose I'd question whether "middle click on the word Put" actually "indicates how to interface with that object or feature," as the Wikipedia article puts it, any more than a menu that says "Save... ^S" on it. There's nothing about either of those that really implies what to do with the text no the screen -- the user has to have information that can't be derived from the UI appearance: in the latter CUA-ish case, that you can click on menu titles and release the mouse button on a command, and that comma
  • Acme SAC supports unlimited undo, a structural regular expression based editing language, mouse chording, plumbing, a programmable shell, networking, an IRC client, a wiki client, and the complete tool set of the Inferno operating system (mk, limbo, debugger, mount, bind, ...)

    and a paaaaartridge in a pear treeee!

    Doesn't emacs have all this?
