What's the magic behind the ELPA?

阅读更多关于 What's the magic behind the ELPA?

问题 I use Aquamacs, and I use ELPA that installs files in ~/.emacs.d/elpa? What's the magic behind this ELPA? I mean, without ELPA, I should download and install the packages in a specific directory, and add those two lines in .emacs. (add-to-list 'load-path "PACKAGE_DIRECTORY") (require 'PACKAGE) But, with ELPA, I don't see anything added to .emacs or /Users/smcho/Library/Preferences/Aquamacs Emacs/{Preferences.el, customizations.el}. How is this possible? Added This is what I found with

Emacs (Cocoa Emacs) vs Aquamacs for running Clojure on Mac OS X

问题 I used Aquamacs so far, and I need to install and run Clojure using SLIME. I googled to get some way to use Clojure on SLIME of Aquamacs, but without success. Questions Is it possible to install Clojure on Aquamacs? Or, can you guess why Clojure on Aquamacs doesn't work? Is it normal that Emacs and Aquamacs can't share the same ELPA? Is it possible to use ELPA to install Conjure on Emacs/Aquamacs? I was told that one can use 'lein swank' to run as a server, do you know how to do that?

Dotfiles repository: Switching from per-package Git submodules to ELPA while maintaining portability

阅读更多关于 Dotfiles repository: Switching from per-package Git submodules to ELPA while maintaining portability

问题 I've been using Git submodules within my dotfiles repository to track each Emacs package that I use. With a package manager being built-in with Emacs 24, though, I'd like to switch to the more official and easier-to-use method. My problem with switching: With my current Git submodule method, any clone of the dotfiles repository is guaranteed to contain all the referenced add-ons. Is there a built-in functionality within this package manager to allow synchronization of packages , so that any

How are the packages installed with 'package-install'(elpa) in Emacs loaded?

阅读更多关于 How are the packages installed with 'package-install'(elpa) in Emacs loaded?

问题 I have installed some packages by using elpa in my Emacs, but how are they loaded when launching Emacs? 回答1: package-install is a part of package.el -- which You can see with describe-function . From package.el documentation: ;; At activation time we will set up the load-path and the info path, ;; and we will load the package's autoloads. If a package's ;; dependencies are not available, we will not activate that package. So in every package there's a file NAME-autoloads.el and this file is

Installing ECB in emacs 24 in ubuntu

问题 I understand from this question that CEDET is installed in emacs 24 without additional installation, so I don't need to follow those instructions here, or the CEDET part here. I am not using the emacs starter kit, like this answer. So, when I use elpa to install ecb, I get the following error: Compiling file /home/mittenchops/.emacs.d/elpa/ecb-20131116.1319/ecb2/jn-file-tree.el at Mon Dec 30 16:13:57 2013 Entering directory `/home/mittenchops/.emacs.d/elpa/ecb-20131116.1319/ecb2/' jn-file
