Emacs 24.4 was released today! Let’s try it
wget http://ftpmirror.gnu.org/emacs/emacs-24.4.tar.xz tar xf emacs-24.4.tar.xz cd emacs-24.4 ./configure make make check sudo make install /usr/local/bin/emacs &
Among other things, it has a new web browser…eww. No, I don’t mind web browsers…that’s its name! Type M-x eww RET to try it. Here’s what the Elixir home page looks like in eww:
Keen!
As I understand it, this will be the last release of Emacs 24. Next up, Emacs 25!
This week, I started the Functional Programming course on edX! Almost all of my recreational programming time has been devoted to Go lately, which is decidedly not functional. But I’m excited about the release of Elixir 1.0 and I’ve been meaning to do more with Clojure, so I think I’ve got a lot more functional programming in my future. Perhaps this course will give me a boost!
The course is not a Haskell course per se, but that’s what it uses for all the examples. I installed the Glasgow Haskell Compiler with
sudo apt-get install ghc
That was easy. Thanks, Debian!
$ cat hello.hs
module Main
where
main=putStrLn "Hello, World!"
$ ghc -o hello hello.hs
[1 of 1] Compiling Main ( hello.hs, hello.o )
Linking hello ...
$ ./hello
Hello, World!
Next I configured Emacs for Haskell by adding
(depends-on "haskell-mode")
to my Cask file and
(use-package haskell-mode :init (progn (add-hook 'haskell-mode-hook 'haskell-indent-mode) (add-hook 'haskell-mode-hook 'interactive-haskell-mode)))
to my Emacs init file. Now I’m ready to try the first set of exercises!
