Emacs 26.1 Released With New Features (lwn.net) 116

Posted by EditorDavid from the church-of-Emacs dept.
There's a new version of the 42-year-old libre text editor with over 2,000 built-in commands, reports LWN.net: Highlights include a built-in Lisp threading mechanism that provides some concurrency, double buffering when running under X, a redesigned flymake mode, 24-bit color support in text mode, and a systemd [user] unit file.
The Free Software Foundation has released a 10,653-word description of all the new features in Emacs 26.1. Here's a couple more:
  • The Emacs server now has socket-launching support. This allows socket based activation, where an external process like systemd can invoke the Emacs server process upon a socket connection event and hand the socket over to Emacs... This new functionality can be disabled with the configure option '--disable-libsystemd'.
  • The new function 'call-shell-region' executes a command in an inferior shell with the buffer region as input.
  • Intercepting hotkeys on Windows 7 and later now works better.
  • The new user variable 'electric-quote-chars' provides a list of curved quotes for 'electric-quote-mode', allowing user to choose the types of quotes to be used.

    Once upon a time, there was a service called inet.d. With inetd it was super easy to write internet activated programs, with almost no extra effort. Service after service got added to inetd, because it was so easy.

    Then one day, someone realized that inetd was a security risk. Not that it was inherently insecure, but that it was in fact harder than you would expect to write an inetd service that was secure, so there were a lot of security holes. As the knowledge of this spread, service after service got removed from inetd, and now on most Unix systems, it's not running at all.

    I find it amazing to have a piece of software that is 42 years old and still in active development. And usage. Think of it: Emacs invented the clipboard. And even though it recently has been beaten by other free editors in performance for larger files I do expect Emacs to take the crown again in upcoming versions.

    I always use Emacs in CLI mode which is where it belongs IMHO.

    Here's to another great 42 years!

      I tried to use it. But when you have a project to do and then have to learn a very complicated piece of software with its own language on top of that, it's overwhelming. I needed to figure out how to get my project done, not learn all the commands to do things that are just a mouse click on other development environments.

      And now they added 20 pages of descriptions for new features.

      Not for me.

        This is a troll, but in case anyone else is wondering, all the basic commands are available in a regular menu in modern emacs. You can learn the basic hot keys as you go, just like any environment. And if you want to, you can learn the more advanced commands. But you don't have to.

          Well, it's been awhile since I tried to use EMACS, but at the time I quit before learning it well because the three finger key commands were actively painful. Since then my hands have become a bit less flexible, and now even things like control commands cause me to need to use both hands. (The shift key is typically much more favorably placed.) So I think EMACS is not an option.

Then I got an Atari 520 ST. It had a minimal word processor, but no good text editor. So I downloaded micro-emacs off usenet from one of the alt-binary newsgroups.

      • Emacs is an IDE, so what exactly is your point?

        If Emacs had by default sane key bindings more people would use it. But as it is a mainly unix utility, potential users go with the mantra: don't change key bindings, because if you have to log on on a "foreign" system the bindings will be different. Hence the pros stick to "editors" that are simpler, guarantied to be installed by default, and have memorizable key bindings.

        One of the hardcore programmers I know used vi/m for a long time, but eventually had to move to a graphical IDE for Java development because of the inline API + arguments completion/documentation. I suspect he was working with a lot of APIs over multiple projects and didn't have them all memorized.

      Please: the emacs kill-ring works far better than the Mac-style "clipboards" -- you can store multiple things in the kill-ring, and pop them off of the stack in sequence (kind of like an *actual* clipboard, to echo one of Ted Nelson's complaints about the Mac-- I mean a clipboard with a really tiny clip that only holds one page? That's good old elegant Zen-master Jobs for you... )

      I wish other editors (any other editors) would take the trouble to copy the aspects of Emacs that are still vastly better all these many years later, so much so to the point where I still leave any IDE from time to time to do editing in Emacs...

      For clipboards, I can copy fragments into named buffers and take them out again super easily, so I can have several different text fragments stored away for easy recall later.
