there's a small bug in line #40 - right bracket missing in (kbd "M-r")

@szimek, thanks for catching that!

@szimek - This no longer works with el-get 3.1. I had to change the bottom (per to:

(setq my-packages
(mapcar 'el-get-source-name el-get-sources)))

(el-get 'sync my-packages)

Hey Matt,

First, thanks so much for providing this emacs config. I'm very excited to be moving away from TextMate and toward Emacs.

So here's my issue: I've follow all of the steps outlined in your blog post, and for the most part this works. The problem is that el-get doesn't seem to be loading any of the packages in el-get-sources. For that matter el-get doesn't seem to want to load itself.

I've modified my script to include the snippet provided by @genexp (per the latest el-get docs). No dice. With or without it, when I run M-x: eval-buffer, I see the following message:

el-get cannot find a recipe for package "el-get"

Not sure what I'm doing wrong, so any help/advice would be greatly appreciated. Here's a gist of my init.el:

Hey tlowrimore - This gist follow up on a blog article here: (which is probably non-obvious). Did you install el-get as show in the post?

tlowrimore commented Feb 6, 2012

Hey @genexp, Thanks for the quick response.

Yes, I did follow the installation procedure outlined in the aforementioned blog post. I noticed that after I cloned the el-get repo into ~/.emacs.d/el-get (resulting in ~/.emacs.d/el-get/el-get) and ran eval-buffer, the cloned repo disappeared (resulting in ~/.emacs.d/el-get). I'm not sure if that's supposed to happen, but it certainly seems suspicious.

In case it helps, I'm on Emacs v24.0.93.

Thanks again for your help.

Hey all

Thanks for the post, @mig and thanks for the help so far @genexp. I also followed instructions and got a similar result. I'll work through the issues and see if I can get it resolved on my own, but if in the meantime you have any advice, I'd appreciate it. I'm sure you're busy, so don't sweat it if not.

When I put in the above gist into my ~/.emacs.d/init.el and run M-x eval-buffer, the size of the text changes, etc, but it doesn't seem to be recognized. I don't get any warnings/errors, just no response.
