  <para>
   When using Nix, you will frequently need to download source code and other files from the internet. Nixpkgs comes with a few helper functions that allow you to fetch fixed-output derivations in a structured way.
  </para>
-
  <para>
   The two fetcher primitives are <function>fetchurl</function> and <function>fetchzip</function>. Both of these have two required arguments, a URL and a hash. The hash is typically <literal>sha256</literal>, although many more hash algorithms are supported. Nixpkgs contributors are currently recommended to use <literal>sha256</literal>. This hash will be used by Nix to identify your source. A typical usage of fetchurl is provided below.

  <para>
   The main difference between <function>fetchurl</function> and <function>fetchzip</function> is in how they store the contents. <function>fetchurl</function> will store the unaltered contents of the URL within the Nix store. <function>fetchzip</function> on the other hand will decompress the archive for you, making files and directories directly accessible in the future. <function>fetchzip</function> can only be used with archives. Despite the name, <function>fetchzip</function> is not limited to .zip files and can also be used with any tarball.
  </para>

  <para>
   <function>fetchpatch</function> works very similarly to <function>fetchurl</function> with the same arguments expected. It expects patch files as a source and and performs normalization on them before computing the checksum. For example it will remove comments or other unstable parts that are sometimes added by version control systems and can change over time.
  </para>

  <para>
   Other fetcher functions allow you to add source code directly from a VCS such as subversion or git. These are mostly straightforward names based on the name of the command used with the VCS system. Because they give you a working repository, they act most like <function>fetchzip</function>.

+  Nixpkgs provides a number of packages that will install Eclipse in its various forms. These range from the bare-bones Eclipse Platform to the more fully featured Eclipse SDK or Scala-IDE packages and multiple version are often available. It is possible to list available Eclipse packages by issuing the command:
+<screen>
+<prompt>$ </prompt>nix-env -f '&lt;nixpkgs&gt;' -qaP -A eclipses --description
+</screen>
+  Once an Eclipse variant is installed it can be run using the <command>eclipse</command> command, as expected. From within Eclipse it is then possible to install plugins in the usual manner by either manually specifying an Eclipse update site or by installing the Marketplace Client plugin and using it to discover and install other plugins. This installation method provides an Eclipse installation that closely resemble a manually installed Eclipse.
+ </para>
+
+ <para>
+  If you prefer to install plugins in a more declarative manner then Nixpkgs also offer a number of Eclipse plugins that can be installed in an <emphasis>Eclipse environment</emphasis>. This type of environment is created using the function <varname>eclipseWithPlugins</varname> found inside the <varname>nixpkgs.eclipses</varname> attribute set. This function takes as argument <literal>{ eclipse, plugins ? [], jvmArgs ? [] }</literal> where <varname>eclipse</varname> is a one of the Eclipse packages described above, <varname>plugins</varname> is a list of plugin derivations, and <varname>jvmArgs</varname> is a list of arguments given to the JVM running the Eclipse. For example, say you wish to install the latest Eclipse Platform with the popular Eclipse Color Theme plugin and also allow Eclipse to use more RAM. You could then add
+<screen>
+packageOverrides = pkgs: {
+  myEclipse = with pkgs.eclipses; eclipseWithPlugins {
+    eclipse = eclipse-platform;
+    jvmArgs = [ "-Xmx2048m" ];
+    plugins = [ plugins.color-theme ];
+  };
+}
+</screen>
+  to your Nixpkgs configuration (<filename>~/.config/nixpkgs/config.nix</filename>) and install it by running <command>nix-env -f '&lt;nixpkgs&gt;' -iA myEclipse</command> and afterward run Eclipse as usual. It is possible to find out which plugins are available for installation using <varname>eclipseWithPlugins</varname> by running
+<screen>
+<prompt>$ </prompt>nix-env -f '&lt;nixpkgs&gt;' -qaP -A eclipses.plugins --description
+</screen>
+ </para>
+
+ <para>
+  If there is a need to install plugins that are not available in Nixpkgs then it may be possible to define these plugins outside Nixpkgs using the <varname>buildEclipseUpdateSite</varname> and <varname>buildEclipsePlugin</varname> functions found in the <varname>nixpkgs.eclipses.plugins</varname> attribute set. Use the <varname>buildEclipseUpdateSite</varname> function to install a plugin distributed as an Eclipse update site. This function takes <literal>{ name, src }</literal> as argument where <literal>src</literal> indicates the Eclipse update site archive. All Eclipse features and plugins within the downloaded update site will be installed.

   On non-NixOS distributions this variable is obviously not set. This can cause regressions in language support or even crashes in some Nixpkgs-provided programs. The simplest way to mitigate this problem is exporting the <literal>LOCALE_ARCHIVE</literal> variable pointing to <literal>${glibcLocales}/lib/locale/locale-archive</literal>. The drawback (and the reason this is not the default) is the relatively large (a hundred MiB) size of the full set of locales.

+   HTTP has a couple different mechanisms for caching to prevent clients from having to download the same content repeatedly if a resource has not changed since the last time it was requested. When nginx is used as a server for static files, it implements the caching mechanism based on the <link xlink:href="https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Last-Modified"><literal>Last-Modified</literal></link> response header automatically; unfortunately, it works by using filesystem timestamps to determine the value of the <literal>Last-Modified</literal> header.

+   Fortunately, HTTP supports an alternative (and more effective) caching mechanism: the <link xlink:href="https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/ETag"><literal>ETag</literal></link> response header. The value of the <literal>ETag</literal> header specifies some identifier for the particular content that the server is sending (e.g. a hash). When a client makes a second request for the same resource, it sends that value back in an <literal>If-None-Match</literal> header. If the ETag value is unchanged, then the server does not need to resend the content.

+  <para>
+   As of NixOS 19.09, the nginx package in Nixpkgs is patched such that when nginx serves a file out of <filename>/nix/store</filename>, the hash in the store path is used as the <literal>ETag</literal> header in the HTTP response, thus providing proper caching functionality. This happens automatically; you do not need to do modify any configuration to get this behavior.

+   The current approach to deploy Steam in NixOS is composing a FHS-compatible chroot environment, as documented <link xlink:href="http://sandervanderburg.blogspot.nl/2013/09/composing-fhs-compatible-chroot.html">here</link>. This allows us to have binaries in the expected paths without disrupting the system, and to avoid patching them to work in a non FHS environment.

+  Weechat can be configured to include your choice of plugins, reducing its closure size from the default configuration which includes all available plugins. To make use of this functionality, install an expression that overrides its configuration such as
+<programlisting>weechat.override {configure = {availablePlugins, ...}: {
+    plugins = with availablePlugins; [ python perl ];
+  }
+}</programlisting>
+  If the <literal>configure</literal> function returns an attrset without the <literal>plugins</literal> attribute, <literal>availablePlugins</literal> will be used automatically.
+ </para>
+
+ <para>
+  The plugins currently available are <literal>python</literal>, <literal>perl</literal>, <literal>ruby</literal>, <literal>guile</literal>, <literal>tcl</literal> and <literal>lua</literal>.
+ </para>
+
+ <para>
+  The python and perl plugins allows the addition of extra libraries. For instance, the <literal>inotify.py</literal> script in weechat-scripts requires D-Bus or libnotify, and the <literal>fish.py</literal> script requires pycrypto. To use these scripts, use the plugin's <literal>withPackages</literal> attribute:
+<programlisting>weechat.override { configure = {availablePlugins, ...}: {
+    plugins = with availablePlugins; [
+            (python.withPackages (ps: with ps; [ pycrypto python-dbus ]))
+        ];
+    };
+}
+</programlisting>
+ </para>
+
+ <para>
+  In order to also keep all default plugins installed, it is possible to use the following method:
+<programlisting>weechat.override { configure = { availablePlugins, ... }: {
+  plugins = builtins.attrValues (availablePlugins // {
+    python = availablePlugins.python.withPackages (ps: with ps; [ pycrypto python-dbus ]);
+  });
+}; }
+</programlisting>
+ </para>
+
+ <para>
+  WeeChat allows to set defaults on startup using the <literal>--run-command</literal>. The <literal>configure</literal> method can be used to pass commands to the program:
+<programlisting>weechat.override {
+  configure = { availablePlugins, ... }: {
+    init = ''
+      /set foo bar
+      /server add freenode chat.freenode.org
+    '';
+  };
+}</programlisting>
+  Further values can be added to the list of commands when running <literal>weechat --run-command "your-commands"</literal>.
+ </para>
+
+ <para>
+  Additionally it's possible to specify scripts to be loaded when starting <literal>weechat</literal>. These will be loaded before the commands from <literal>init</literal>:
+<programlisting>weechat.override {
+  configure = { availablePlugins, ... }: {
+    scripts = with pkgs.weechatScripts; [
+      weechat-xmpp weechat-matrix-bridge wee-slack

+  };
+}</programlisting>
+ </para>
+
+ <para>
+  In <literal>nixpkgs</literal> there's a subpackage which contains derivations for WeeChat scripts. Such derivations expect a <literal>passthru.scripts</literal> attribute which contains a list of all scripts inside the store path. Furthermore all scripts have to live in <literal>$out/share</literal>. An exemplary derivation looks like this:
+<programlisting>{ stdenv, fetchurl }:

-   Nixpkgs provides a number of packages that will install Eclipse in its various forms. These range from the bare-bones Eclipse Platform to the more fully featured Eclipse SDK or Scala-IDE packages and multiple version are often available. It is possible to list available Eclipse packages by issuing the command:
-<screen>
-<prompt>$ </prompt>nix-env -f '&lt;nixpkgs&gt;' -qaP -A eclipses --description
-</screen>
-   Once an Eclipse variant is installed it can be run using the <command>eclipse</command> command, as expected. From within Eclipse it is then possible to install plugins in the usual manner by either manually specifying an Eclipse update site or by installing the Marketplace Client plugin and using it to discover and install other plugins. This installation method provides an Eclipse installation that closely resemble a manually installed Eclipse.

-   If you prefer to install plugins in a more declarative manner then Nixpkgs also offer a number of Eclipse plugins that can be installed in an <emphasis>Eclipse environment</emphasis>.

This function takes as argument <literal>{ eclipse, plugins ? [], jvmArgs ?

For example, say you wish to install the latest Eclipse Platform with the popular Eclipse Color Theme plugin and also allow Eclipse to use more RAM. You could then add

Use the <varname>buildEclipseUpdateSite</varname> function to install a plugin distributed as an Eclipse update site. This function takes <literal>{ name, src }</literal> as argument where <literal>src</literal> indicates the Eclipse update site archive. All Eclipse features and plugins within the downloaded update site will be installed. When an update site archive is not available then the <varname>buildEclipsePlugin</varname> function can be used to install a plugin that consists of a pair of feature and plugin JARs. This function takes an argument <literal>{ name, srcFeature, srcPlugin }</literal> where <literal>srcFeature</literal> and <literal>srcPlugin</literal> are the feature and plugin JARs, respectively.

-    HTTP has a couple different mechanisms for caching to prevent clients from having to download the same content repeatedly if a resource has not changed since the last time it was requested. When nginx is used as a server for static files, it implements the caching mechanism based on the <link xlink:href="https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Last-Modified"><literal>Last-Modified</literal></link> response header automatically; unfortunately, it works by using filesystem timestamps to determine the value of the <literal>Last-Modified</literal> header. This doesn't give the desired behavior when the file is in the Nix store, because all file timestamps are set to 0 (for reasons related to build reproducibility).
-   </para>

-   <para>
-    Fortunately, HTTP supports an alternative (and more effective) caching mechanism: the <link xlink:href="https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/ETag"><literal>ETag</literal></link> response header. The value of the <literal>ETag</literal> header specifies some identifier for the particular content that the server is sending (e.g. a hash). When a client makes a second request for the same resource, it sends that value back in an <literal>If-None-Match</literal> header. If the ETag value is unchanged, then the server does not need to resend the content.
-   </para>
-
-   <para>
-    As of NixOS 19.09, the nginx package in Nixpkgs is patched such that when nginx serves a file out of <filename>/nix/store</filename>, the hash in the store path is used as the <literal>ETag</literal> header in the HTTP response, thus providing proper caching functionality. This happens automatically; you do not need to do modify any configuration to get this behavior.

-  </para>
-
-  <para>
-   The plugins currently available are <literal>python</literal>, <literal>perl</literal>, <literal>ruby</literal>, <literal>guile</literal>, <literal>tcl</literal> and <literal>lua</literal>.
-  </para>
-
-  <para>
-   The python and perl plugins allows the addition of extra libraries. For instance, the <literal>inotify.py</literal> script in weechat-scripts requires D-Bus or libnotify, and the <literal>fish.py</literal> script requires pycrypto. To use these scripts, use the plugin's <literal>withPackages</literal> attribute:
-<programlisting>weechat.override { configure = {availablePlugins, ...}: {
-    plugins = with availablePlugins; [
-            (python.withPackages (ps: with ps; [ pycrypto python-dbus ]))
-        ];
-    };
-}
-</programlisting>
-  </para>
-
-  <para>
-   In order to also keep all default plugins installed, it is possible to use the following method:
-<programlisting>weechat.override { configure = { availablePlugins, ... }: {
-  plugins = builtins.attrValues (availablePlugins // {
-    python = availablePlugins.python.withPackages (ps: with ps; [ pycrypto python-dbus ]);
-  });
-}; }
-</programlisting>
-  </para>
-
-  <para>
-   WeeChat allows to set defaults on startup using the <literal>--run-command</literal>. The <literal>configure</literal> method can be used to pass commands to the program:
-<programlisting>weechat.override {
-  configure = { availablePlugins, ... }: {
-    init = ''
-      /set foo bar
-      /server add freenode chat.freenode.org
-    '';
-  };
-}</programlisting>
-   Further values can be added to the list of commands when running <literal>weechat --run-command "your-commands"</literal>.
-  </para>
-
-  <para>
-   Additionally it's possible to specify scripts to be loaded when starting <literal>weechat</literal>. These will be loaded before the commands from <literal>init</literal>:
-<programlisting>weechat.override {
-  configure = { availablePlugins, ... }: {
-    scripts = with pkgs.weechatScripts; [
-      weechat-xmpp weechat-matrix-bridge wee-slack
-    ];
-    init = ''
-      /set plugins.var.python.jabber.key "val"
-    '':
-  };
-}</programlisting>
-  </para>
-
-  <para>
-   In <literal>nixpkgs</literal> there's a subpackage which contains derivations for WeeChat scripts. Such derivations expect a <literal>passthru.scripts</literal> attribute which contains a list of all scripts inside the store path. Furthermore all scripts have to live in <literal>$out/share</literal>. An exemplary derivation looks like this:
-<programlisting>{ stdenv, fetchurl }:
-
-stdenv.mkDerivation {
-  name = "exemplary-weechat-script";
-  src = fetchurl {
-    url = "https://scripts.tld/your-scripts.tar.gz";
-    sha256 = "...";
-  };
-  passthru.scripts = [ "foo.py" "bar.lua" ];
-  installPhase = ''
-    mkdir $out/share
-    cp foo.py $out/share
-    cp bar.lua $out/share
-  '';
-}</programlisting>

 This manual primarily describes how to write packages for the Nix Packages collection
 (Nixpkgs). Thus it’s mainly for packagers and developers who want to add packages to
 Nixpkgs. If you like to learn more about the Nix package manager and the Nix
-expression language, then you are kindly referred to the [Nix manual](http://nixos.org/nix/manual/).

+The NixOS distribution is documented in the [NixOS manual](https://nixos.org/nixos/manual/).
 
 ## Overview of Nixpkgs
 
 Nix expressions describe how to build packages from source and are collected in
 the [nixpkgs repository](https://github.com/NixOS/nixpkgs). Also included in the
 collection are Nix expressions for
-[NixOS modules](http://nixos.org/nixos/manual/index.html#sec-writing-modules).
+[NixOS modules](https://nixos.org/nixos/manual/index.html#sec-writing-modules).
 With these expressions the Nix package manager can build binary packages.
 
 Packages, including the Nix packages collection, are distributed through
-[channels](http://nixos.org/nix/manual/#sec-channels). The collection is
+[channels](https://nixos.org/nix/manual/#sec-channels). The collection is
 distributed for users of Nix on non-NixOS distributions through the channel
 `nixpkgs`. Users of NixOS generally use one of the `nixos-*` channels, e.g.
-`nixos-16.03`, which includes all packages and modules for the stable NixOS
-16.03. Stable NixOS releases are generally only given
+`nixos-19.09`, which includes all packages and modules for the stable NixOS
+19.09. Stable NixOS releases are generally only given
 security updates. More up to date packages and modules are available via the
 `nixos-unstable` channel.
 
 Both `nixos-unstable` and `nixpkgs` follow the `master` branch of the Nixpkgs
 repository, although both do lag the `master` branch by generally
-[a couple of days](http://howoldis.herokuapp.com/). Updates to a channel are

 distributed as soon as all tests for that channel pass, e.g.
