emacs on mac os x, how to get spell check to work

Question

I\'m moving from Windows to Mac, and I\'ve spent the whole night trying to get emacs to work.

I\'ve installed GNU emacs and simply copied over my Windows .ema

Answer 1

I use aspell from Homebrew. Simply:

brew install aspell --with-lang-en

Then, make sure your brew bin directory is in your Emacs exec-path variable. If you use /usr/local as your brew prefix then it will just work since that path is included in exec-path by default. Otherwise you'll need this somewhere in your .emacs:

  (setq exec-path (append "/path/to/brew/bin" exec-path)))

You can also accomplish the same thing using the customize interface with "M-x customize-variable RET exec-path RET" and then using the gui to add a path.

This will work on any Emacs, including the one from Emacs for Mac OS X, the one from brew, or the system Emacs.

Answer 2

Making a symbolic link in /usr/bin on OS X 10.12 (Sierra) is not permitted or necessary (or a good idea).

[iMac ~]$ sudo ln -s /usr/local/bin/ispell /usr/bin/ispell
ln: /usr/bin/ispell: Operation not permitted

I used that hack for years, but was finally forced to figure out the right solution when the last upgrade deleted it. I used homebrew to install ispell and apsell and would get which ever one I set in ~/.emacs with

[iMac ~]$ cat ~/.emacs
(setq ispell-program-name "/usr/local/bin/aspell")

There is a similar discussion of this here.

-lrm

Answer 3

Installing aspell, and adding (setq ispell-program-name "/usr/local/bin/aspell") in the init.el does not work for me. I had to make a symbolic link sudo ln -s /usr/local/bin/aspell /usr/bin/ispell, then emacs flyspell-mode works OK.

Answer 4

I build on the answers by katspaugh, David Caldwell, and Ébe Isaac, and made it work with the latest versions.

Install aspell, for example with brew:

brew install aspell

brew symlinks to /usr/local/bin and you can verify the installation:

$ which aspell
/usr/local/bin/aspell

Now tell Emacs about this location, e.g. adding this line in ~/.emacs:

(setq ispell-program-name "/opt/local/bin/aspell")

Launch M-x ispell in a buffer and it works.

To install with ports, see other answers.

Answer 5

Here is a MacPorts solution to the problem. (Credits to this link)

$ sudo port install aspell

Then install one of aspell's dictionaries for the respective language support

$ sudo port install aspell-dict-en

Then add the following line to your init.el or .emacs file.

(setq ispell-program-name "/opt/local/bin/aspell")

It worked for me.

Note: "sudo ports install ispell" works as well, but it is not as efficient and flexible as aspell.

Answer 6

It also works if you use fink instead than home-brew. ispell will be in /sw/bin and the string to add to .emacs file will be:

(setq ispell-program-name "/sw/bin/ispell")
