<para>The command <command>nix-install-package</command> interactively
|
||||
installs a Nix Package file (<filename>*.nixpkg</filename>), which is
|
||||
a small file that contains a store path to be installed along with the
|
||||
URL of a binary cache. The Nix Package file is either
|
||||
<replaceable>file</replaceable>, or automatically downloaded from
|
||||
<replaceable>url</replaceable> if the <option>--url</option> switch is
|
||||
used.</para>

<para><command>nix-install-package</command> is used in <link

linkend="sec-one-click">one-click installs</link> to download and
|

install pre-built binary packages with all necessary dependencies.
|
||||
<command>nix-install-package</command> is intended to be associated
|
||||
with the MIME type <literal>application/nix-package</literal> in a web
|
||||
browser so that it is invoked automatically when you click on
|
||||
<filename>*.nixpkg</filename> files. When invoked, it restarts itself
|
||||
in a terminal window (since otherwise it would be invisible when run
|
||||
from a browser), asks the user to confirm whether to install the
|
||||
package, and if so downloads and installs the package into the user’s
|
||||
current profile.</para>

<para>Often, when you want to install a specific package (e.g., from

the <link

xlink:href="http://nixos.org/nixpkgs/">Nix
|
||||
Packages collection</link>), subscribing to a channel is a bit

cumbersome. And channels don’t help you at all if you want to install

an older version of a package than the one provided by the current
|

contents of the channel, or a package that has been removed from the
|
||||
channel. That’s when <emphasis>one-click installs</emphasis> come in

handy: you can just go to the web page that contains the package,

click on it, and it will be installed with all the necessary

<para>For instance, you can go to <link

do with <literal>application/nix-package</literal> files. You should
|
||||
open them with <filename>/nix/bin/nix-install-package</filename>.
|
||||
This will open a window that asks you to confirm that you want to
|

install the package. When you answer <literal>Y</literal>, the

package and all its dependencies will be installed. This is a binary
