;;; el-get.el --- Manage the external elisp bits and pieces you depend upon
;;
;; Copyright (C) 2010 Dimitri Fontaine
;;
;; Author: Dimitri Fontaine <[email protected]>
;; URL: http://www.emacswiki.org/emacs/el-get.el
;; Version: 2.2
;; Created: 2010-06-17
;; Keywords: emacs package elisp install elpa git git-svn bzr cvs svn darcs hg
;; apt-get fink pacman http http-tar emacswiki
;; Licence: WTFPL, grab your copy here: http://sam.zoy.org/wtfpl/
;;
;; This file is NOT part of GNU Emacs.
;;
;; Install
;; Please see the README.asciidoc file from the same distribution
;;; Commentary:
;;
;; Version String are now inspired by how Emacs itself numbers its version.
;; First is the major version number, then a dot, then the minor version
;; number. The minor version number is 0 when still developping the next
;; major version.
;;
;; So 2.0 is a developer release while 2.1 will be the next stable release.
;;
;; Please note that this versioning policy has been picked while backing
;; 1.2~dev, so 1.0 was a "stable" release in fact. Ah, history.
;;; Change Log:
;;
;; 3.0 - WIP - Get a fix
;;
;; - support fo package dependencies
;; - rely on package status for `el-get' to install and init them
;; - M-x el-get-list-packages
;; - support for :branch in git
;; - new recipes, galore
;; - bug fixes, byte compiling, windows compatibility, etc
;; - recipe files are now *.rcp rather than *.el (el still supported)
;;
;; 2.2 - 2011-05-26 - Fix the merge
;;
;; - Revert changes introduced by a merge done by mistake
;;
;; 2.1 - 2011-05-25 - Still growing, getting lazy
;;
;; - Add support for autoloads, per Dave Abrahams
;; - fix 'wait support for http (using sync retrieval)
;; - code cleanup per Dave Abrahams, lots of it
;; - add function M-x el-get-update-all
;; - Implement M-x el-get-make-recipes
;; - byte-compile at build time rather than at init time
;; - and use a "clean room" external emacs -Q for byte compiling
;; - allow to skip autoloads either globally or per-package
;; - better checks and errors for commands used when installing packages
;; - register `el-get-sources' against the custom interface
;; - el-get will now accept a list of sources to install or init
;; - open el-get-{install,init,remove,update} from `el-get-sources' only
;; - add :prepare and :post-init and :lazy, and `el-get-is-lazy'
;; - add support for :repo for ELPA packages
;;
;; 1.1 - 2010-12-20 - Nobody's testing until the release
;;
;; - Adapt to package.el from Emacs24 by using relative symlinks to ELPA
;; packages ((package-user-dir) is "~/.emacs.d/elpa" now, so needs to
;; get expanded at least)
;; - Allow to bypass byte compiling entirely with a single global var
;; - Have http local file default to something sane, not package.el
;; - Implement support for svn and darcs too
;; - Still more recipes
;; - Add support for the `pacman' package manager (ARCH Linux)
;; - Add support for mercurial
;; - (el-get 'sync) now really means synchronous, and serialized too
;; - el-get-start-process-list implements :sync, defaults to nil (async)
;; - Implement a :localname package property to help with some kind of URLs
;; - Add el-get-post-init-hooks
;; - Allow build commands to be evaluated, hence using some emacs variables
;; - Finaly walk the extra mile and remove "required" packages at install
;; - Implement support for the "Do you want to continue" apt-get prompt
;; - implement :before user defined function to run before init
;;
;; 1.0 - 2010-10-07 - Can I haz your recipes?
;;
;; - Implement el-get recipes so that el-get-sources can be a simple list
;; of symbols. Now that there's an authoritative git repository, where
;; to share the recipes is easy.
;; - Add support for emacswiki directly, save from having to enter the URL
;; - Implement package status on-disk saving so that installing over a
;; previously failed install is in theory possible. Currently `el-get'
;; will refrain from removing your package automatically, though.
;; - Fix ELPA remove method, adding a "removed" state too.
;; - Implement CVS login support.
;; - Add lots of recipes
;; - Add support for `system-type' specific build commands
;; - Byte compile files from the load-path entries or :compile files
;; - Implement support for git submodules with the command
;; `git submodule update --init --recursive`
;; - Add catch-all post-install and post-update hooks
;; - Add desktop notification on install/update.
;;
;; 0.9 - 2010-08-24 - build me a shell
;;
;; - have `el-get-build' use start-process-shell-command so that you can
;; pass-in shell commands. Beware of poor command argument "parsing"
;; though, done with a simple `split-string'.
;;
;; 0.8 - 2010-08-23 - listen to the users
;;
;; - implement :after user defined function to run at the end of init
;; - add CVS support (no login support)
;; - improve el-get-build to use async building
;; - fix el-get-update doing so
;;
;; 0.7 - 2010-08-23 - archive
;;
;; - http support is extended to `tar' archives, via the http-tar type
;;
;; 0.6 - 2010-08-12 - towards a stable version
;;
;; - fix when asynchronous http support call post-install-fun
;; - fix el-get-remove calling convention
;; - add support for bzr, thanks to Kevin Fletcher
;;
;; 0.5 - 2010-08-06 - release early, fix often
;;
;; - fix apt-get and fink install hooks to call el-get-dpkg-symlink
;; - fix elpa and http support to follow the new call convention
;; - use asynchronous url-retrieve facility so that http is async too
;;
;; 0.4 - 2010-08-04 - foxy release
;;
;; - support asynchronous processes for system commands
;; apt-get, fink, git and git-svn are run in background
;; - support `sudo' password prompts (classic and ubuntu variants)
;; - fix fink support
;; - ELPA support is an option so that you can install ELPA from el-get
;; - implement el-get-rmdir
;;; Code:
(require 'dired)
(require 'package nil t) ; that's ELPA, but you can use el-get to install it
(require 'cl) ; needed for `remove-duplicates'
(require 'simple) ; needed for `apply-partially'
(require 'bytecomp)
(require 'autoload)
(require 'help-mode) ; byte-compiling needs to know about xref-type buttons

"Additional package recipes
Each entry is a PLIST where the following properties are
supported.
If your property list is missing the :type property, then it's
merged with the recipe one, so that you can override any
definition provided by `el-get' recipes locally.
:name
The name of the package. It can be different from the name of
the directory where the package is stored (after a `git
clone' for example, in which case a symlink will be created.
:depends
A single package name, or a list of package names, on which
the package depends. All of a packages dependencies will be
installed before the package is installed.
:pkgname
The name of the package for the underlying package management
system (`apt-get', `fink' or `pacman', also supported by
`emacsmirror'), which can be different from the Emacs package
name.
:type
The type of the package, currently el-get offers support for
`apt-get', `elpa', `git', `emacsmirror', `git-svn', `bzr' `svn',
`cvs', `darcs', `fink', `ftp', `emacswiki', `http-tar', `pacman',
`hg' and `http'. You can easily support your own types here,
see the variable `el-get-methods'.
:branch
Which branch to fetch when using `git'. Also supported in
the installer in `el-get-install'.
:url
Where to fetch the package, only meaningful for `git' and `http' types.
:build
Your build recipe, a list.
A recipe R whose `car' is not a string will be replaced
by (eval R).
Then, each element of the recipe will be interpreted as
a command:
* If the element is a string, it will be interpreted directly
by the shell.
* Otherwise, if it is a list, any list sub-elements will be
recursively \"flattened\" (see `el-get-flatten'). The
resulting strings will be interpreted as individual shell
arguments, appropriately quoted.
:build/system-type
Your specific build recipe for a given `system-type' gets
there and looks like :build.
:load-path
A directory or a list of directories you want `el-get' to add
to your `load-path'. Those directories are relative to where
the package gets installed.
:compile
Allow to restrict what to byte-compile: by default, `el-get'
will compile all elisp files in the :load-path directories,
unless a :build command exists for the package source. Given
a :compile property, `el-get' will only byte-compile those
given files, directories or filename-regexpes in the property
value. This property can be a `listp' or a `stringp' if you
want to compile only one of those.
:info
This string allows you to setup a directory where to find a
'package.info' file, or a path/to/whatever.info file. It will
even run `ginstall-info' for you to create the `dir' entry so
that C-h i will be able to list the newly installed
documentation. Note that you might need to kill (C-x k) your
info buffer then C-h i again to be able to see the new menu
entry.
:load
List of files to load, or a single file to load after having
installed the source but before `require'ing its features.
:features
List of features el-get will `require' for you.
:autoloads
Control whether el-get should generate autoloads for this
package. Setting this to nil prevents el-get from generating
autoloads for the package. Default is t. Setting this to a
string or a list of string will load the named autoload
files.
:library
When using :after but not using :features, :library allows to
set the library against which to register the :after function
against `eval-after-load'. It defaults to either :pkgname
or :package, in this order. See also `el-get-eval-after-load'.
:options
Currently used by http-tar and cvs support.
When using http-tar, it allows you to give the tar options
you want to use. Typically would be \"xzf\", but you might
want to choose \"xjf\" for handling .tar.bz files e.g.
When using CVS, when it's set to \"login\", `el-get' will
first issue a `cvs login' against the server, asking you
interactively (in the minibuffer) any password you might to
enter, and only then it will run the `cvs checkout' command.
:module
Currently only used by the `cvs' support, allow you to
configure the module you want to checkout in the given URL.
:repo
Only used by the `elpa' support, a cons cell with the
form (NAME . URL), as in `package-archives'. If the package
source only specifies a URL, the URL will be used for NAME as
well.
:prepare
Intended for use from recipes, it will run once both the
`Info-directory-list' and the `load-path' variables have been
taken care of, but before any further action from
`el-get-init'.
:before
A pre-init function to run once before `el-get-init' calls
`load' and `require'. It gets to run with `load-path'
already set, and after :prepare has been called. It's not
intended for use from recipes.
:post-init
Intended for use from recipes. This function is registered
for `eval-after-load' against the recipe library by
`el-get-init' once the :load and :features have been setup.
:after
A function to register for `eval-after-load' against the
recipe library, after :post-init. That's not intended for
recipe use.
:lazy
Default to nil. Allows to override `el-get-is-lazy' per
package.
:localname
Currently only used by both `http' and `ftp' supports, allows
to specify the target name of the downloaded file.
This option is useful if the package should be retrieved using
a presentation interface (such as as web SCM tool).
For example, destination should be set to \"package.el\" if
the package url has the following scheme:
\"http://www.example.com/show-as-text?file=path/package.el\"
:website
The website of the project.
