w3m-mode in emacs on osx

December 19, 2008 12:34 PM

Emacsfilter: Anyone had luck installing w3m to Emacs on OS X?

I'm an almost complete novice with emacs. I've successfully gotten org-mode and remember.el to work by adding their directories to the load path in .emacs.

I can't get the same to happen for w3m. I've run make and make install, no dice. I've copied the individual .el files to site-lisp inside of emacs, no luck.

I've follow a couple of sets of 'how-to' directions online, but none seem to work. I always get the error:

'Install w3m command in 'exec-path' or set 'w3m-command' variable correctly.'

Thoughts?

I'm running the GUI version of gnu emacs (i.e. not from the console) if that helps.

Does w3m run from the terminal? It sounds like emacs is loading w3m-mode, trying to run w3m, and giving up. If your w3m is from macports or fink, it might live under /sw or /opt, and emacs might not inherit those paths from the shell for some reason.

Off-topic: if OS X is your first experience with emacs, you might try Aquamacs.

What are the values of Emacs' exec-path and w3m-command variables? You can check by using C-h v to run describe-variable. It would seem either that w3m is not in any of the directories in exec-path, or something is wrong with w3m-command. If you know where the w3m binary is installed and that directory isn't in exec-path, you can add this to your ~/.emacs file:

(setq exec-path (cons "/path/to/w3m/binary" exec-path))

w3m doesn't run from terminal either, but that would be a different instance of emacs, yes?

adding path to w3m doesn't work either, letourneau, same error.

w3m-command is nil, how should I set it?

fantabulous: Didn't care for Aquamacs, the mix of osxy and emacs just confused me. I just want to learn pure emacs stuff that'll work cross platform.

mrstrotsky: what you seem to misunderstand is that w3m is a seperate program from emacs. It is when w3m runs inside emacs (almost like the opposite of a browser plugin) that it becomes really useful and interesting. w3m needs to be installed seperately and independantly for emacs w3m mode to work.

Yeah, I think idiopath has it. The Emacs w3m-mode is just a wrapper around the w3m browser, which is a separate, independent piece of software. Here's the download page for w3m at Sourceforge. You'll need to install the OS X Developer Tools to build the app from source, unless you can find a compiled OS X binary (I didn't see any in a quick Google search). Once you build w3m, you can add the location of the binary to the Emacs exec-path list (which on second thought I should have suggested you do as (add-to-list 'exec-path "/path/to/w3m"), but whatever), and w3m-mode should be able to fire up w3m in an Emacs buffer.

Boingo-Boing! Edited .emacs, ran ./config make and make install on w3m again, and it worked! Groovy! Thanks gang!
