## Installing
|
|
|
|
To add the repository put this before the call to `package-initialize`
|
|
in your `init.el` file.
|
|
|
|
<!-- <script src="https://gist.github.com/1679158.js"> </script> -->
|
|
|
|
(add-to-list 'package-archives
|
|
'("melpa" . "http://melpa.milkbox.net/packages/") t)
|
|
|
|
|
|
Please read about [known issues](#known-issues) below before
|
|
attempting to install multiple packages at once.
|
|
|
|
### Customizations
|
|
|
|
There is currently no way in `package.el` to exclude or include versions. So to remedy this there is a `melpa.el` package--available in MELPA--that will allow you to enable only certain packages or exclude certain packages. You can install the package manually by pasting this into yoru `*scratch*` buffer and evaluating it.
|
|
|
|
(progn
|
|
(switch-to-buffer
|
|
(url-retrieve-synchronously
|
|
"https://raw.github.com/milkypostman/melpa/master/melpa.el"))
|
|
(package-install-from-buffer (package-buffer-info) 'single))
|
|
|
|
|
|
You can then customize two variables:
|
|
|
|
`package-archive-enable-alist`
|
|
: Optional Alist of enabled packages used by `package-filter'.
|
|
The format is (ARCHIVE . PACKAGE ...), where ARCHIVE is a string
|
|
matching an archive name in `package-archives', PACKAGE is a
|
|
symbol of a package in ARCHIVE to enable.
|
|
|
|
If no ARCHIVE exists in the alist, all packages are enabled.
|
|
|
|
|
|
`package-archive-exclude-alist`
|
|
: Alist of packages excluded by `package-filter'.
|
|
The format is (ARCHIVE . PACKAGE ...), where ARCHIVE is a string
|
|
matching an archive name in `package-archives', PACKAGE is a
|
|
symbol of a package in that archive to exclude.
|
|
|
|
Any specified package is excluded regardless of the value of
|
|
`package-archive-enable-alist'
|
|
|
|
|
|
|
|
## Known Issues
|
|
|
|
**Note:** *This fix are included in the `melpa.el` package.*
|
|
|
|
There is a small bug in Emacs24's `package.el` the order for
|
|
dependencies comes out backwards for what I needed. the problem is
|
|
patched by some *advice*.
|
|
|
|
<!-- <script src="https://gist.github.com/1679232.js"> </script> -->
|
|
|
|
(defadvice package-compute-transaction
|
|
(before
|
|
package-compute-transaction-reverse (package-list requirements)
|
|
activate compile)
|
|
"reverse the requirements"
|
|
(setq requirements (reverse requirements))
|
|
(print requirements))
|
|
|
|
|
|
|
|
## Updating Packages
|
|
|
|
`package.el` now includes a mechanism to upgrade packages. After running `package-list-packages`, type *u* (mark Upgradable packages) and then *x* (eXecute the installs and deletions). When it's done installing all the packages it will ask if you want to delete the obsolete packages and so you can hit *y* (Yes).
|
|
|
|
If you run into a problem installing or upgrading, you may need to go into your `~/.emacs.d/elpa/` directory and delete packages that are installed multiple times. This can happen when the install times out (see [Known Issues](#known-issues)).

## Development
|
|
|
|
[https://github.com/milkypostman/melpa](https://github.com/milkypostman/melpa)
|
|
|
|
Contributions are welcome. Currently, the builder only supports
|
|
packages using git, subversion, mercurial, and darcs. This covers
|
|
most of the packages that I am interested in.
