Thank you for your contributions.
This has been automatically marked as stale because it has had no
activity for 180 days.
If this is still important to you, we ask that you leave a
comment below. Your comment can be as simple as "still important
to me". This lets people see that at least one person still cares
about this. Someone will have to do this at most twice a year if
there is no other activity.
Here are suggestions that might help resolve this more quickly:
1. Search for maintainers and people that previously touched the
related code and @ mention them in a comment.
2. Ask on the [NixOS Discourse](https://discourse.nixos.org/).
3. Ask on the [#nixos channel](irc://irc.freenode.net/#nixos) on

<title>Fetchers</title>
<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>

]]></programlisting>
<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>.

</para>
<para>
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. 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.

The Emacs package comes with some extra helpers to make it easier to configure. <varname>emacsWithPackages</varname> allows you to manage packages from ELPA. This means that you will not have to install that packages from within Emacs. For instance, if you wanted to use <literal>company</literal>, <literal>counsel</literal>, <literal>flycheck</literal>, <literal>ivy</literal>, <literal>magit</literal>, <literal>projectile</literal>, and <literal>use-package</literal> you could use this as a <filename>~/.config/nixpkgs/config.nix</filename> override:

}
</screen>
<para>
You can install it like any other packages via <command>nix-env -iA myEmacs</command>. However, this will only install those packages. It will not <literal>configure</literal> them for us. To do this, we need to provide a configuration file. Luckily, it is possible to do this from within Nix! By modifying the above example, we can make Emacs load a custom config file. The key is to create a package that provide a <filename>default.el</filename> file in <filename>/share/emacs/site-start/</filename>. Emacs knows to load this file automatically when it starts.

Sometimes <varname>emacsWithPackages</varname> is not enough, as this package set has some priorities imposed on packages (with the lowest priority assigned to Melpa Unstable, and the highest for packages manually defined in <filename>pkgs/top-level/emacs-packages.nix</filename>). But you can't control this priorities when some package is installed as a dependency. You can override it on per-package-basis, providing all the required dependencies manually - but it's tedious and there is always a possibility that an unwanted dependency will sneak in through some other package. To completely override such a package you can use <varname>overrideScope'</varname>.

<title>Linux kernel</title>
<para>
The Nix expressions to build the Linux kernel are in <link
xlink:href="https://github.com/NixOS/nixpkgs/blob/master/pkgs/os-specific/linux/kernel"><filename>pkgs/os-specific/linux/kernel</filename></link>.
</para>
<para>
The function that builds the kernel has an argument <varname>kernelPatches</varname> which should be a list of <literal>{name, patch, extraConfig}</literal> attribute sets, where <varname>name</varname> is the name of the patch (which is included in the kernel’s <varname>meta.description</varname> attribute), <varname>patch</varname> is the patch itself (possibly compressed), and <varname>extraConfig</varname> (optional) is a string specifying extra options to be concatenated to the kernel configuration file (<filename>.config</filename>).
</para>
<para>
The kernel derivation exports an attribute <varname>features</varname> specifying whether optional functionality is or isn’t enabled. This is used in NixOS to implement kernel-specific behaviour. For instance, if the kernel has the <varname>iwlwifi</varname> feature (i.e. has built-in support for Intel wireless chipsets), then NixOS doesn’t have to build the external <varname>iwlwifi</varname> package:
<programlisting>
modulesTree = [kernel]
++ pkgs.lib.optional (!kernel.features ? iwlwifi) kernelPackages.iwlwifi
++ ...;
</programlisting>

</para>
</listitem>

Now we’re going to update the kernel configuration. First unpack the kernel. Then for each supported platform (<literal>i686</literal>, <literal>x86_64</literal>, <literal>uml</literal>) do the following:

<listitem>
<para>
Make an copy from the old config (e.g. <filename>config-2.6.21-i686-smp</filename>) to the new one (e.g. <filename>config-2.6.22-i686-smp</filename>).
</para>
</listitem>
<listitem>
<para>
Copy the config file for this platform (e.g. <filename>config-2.6.22-i686-smp</filename>) to <filename>.config</filename> in the kernel source tree.
</para>
</listitem>
<listitem>
<para>
Run <literal>make oldconfig ARCH=<replaceable>{i386,x86_64,um}</replaceable></literal> and answer all questions. (For the uml configuration, also add <literal>SHELL=bash</literal>.) Make sure to keep the configuration consistent between platforms (i.e. don’t enable some feature on <literal>i686</literal> and disable it on <literal>x86_64</literal>).
</para>
</listitem>
<listitem>
<para>
If needed you can also run <literal>make menuconfig</literal>:

</orderedlist>
</para>
</listitem>
<listitem>
<para>

</para>
</listitem>
<listitem>
<para>
It may be that the new kernel requires updating the external kernel modules and kernel-dependent packages listed in the <varname>linuxPackagesFor</varname> function in <filename>all-packages.nix</filename> (such as the NVIDIA drivers, AUFS, etc.). If the updated packages aren’t backwards compatible with older kernels, you may need to keep the older versions around.

<title>Locales</title>
<para>
To allow simultaneous use of packages linked against different versions of <literal>glibc</literal> with different locale archive formats Nixpkgs patches <literal>glibc</literal> to rely on <literal>LOCALE_ARCHIVE</literal> environment variable.
</para>
<para>
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. It is possible to build a custom set of locales by overriding parameters <literal>allLocales</literal> and <literal>locales</literal> of the package.

<title>ETags on static files served from the Nix store</title>
<para>
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>
All users of Nixpkgs are free software users, and many users (and developers) of Nixpkgs want to limit and tightly control their exposure to unfree software. At the same time, many users need (or want) to run some specific pieces of proprietary software. Nixpkgs includes some expressions for unfree software packages. By default unfree software cannot be installed and doesn’t show up in searches. To allow installing unfree software in a single Nix invocation one can export <literal>NIXPKGS_ALLOW_UNFREE=1</literal>. For a persistent solution, users can set <literal>allowUnfree</literal> in the Nixpkgs configuration.
</para>
<para>
Fine-grained control is possible by defining <literal>allowUnfreePredicate</literal> function in config; it takes the <literal>mkDerivation</literal> parameter attrset and returns <literal>true</literal> for unfree packages that should be allowed.

<title>Weechat</title>
<para>
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
];
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

<para>
If the expression for a package requires derivation attributes that the generator cannot figure out automatically (say, <varname>patches</varname> or a <varname>postInstall</varname> hook), you should modify <filename>pkgs/servers/x11/xorg/overrides.nix</filename>.

Updating the <link xlink:href="https://hex.pm">Hex</link> package set requires <link
xlink:href="https://github.com/erlang-nix/hex2nix">hex2nix</link>. Given the path to the Erlang modules (usually <literal>pkgs/development/erlang-modules</literal>), it will dump a file called <literal>hex-packages.nix</literal>, containing all the packages that use a recognized build system in <link
xlink:href="https://hex.pm">Hex</link>. It can't be determined, however, whether every package is buildable.
</para>
<para>
To make life easier for our users, try to build every <link
xlink:href="https://hex.pm">Hex</link> package and remove those that fail. To do that, simply run the following command in the root of your <literal>nixpkgs</literal> repository:
</para>
<screen>
<prompt>$ </prompt>nix-build -A beamPackages
</screen>
<para>
That will attempt to build every package in <literal>beamPackages</literal>. Then manually remove those that fail. Hopefully, someone will improve <link
xlink:href="https://github.com/erlang-nix/hex2nix">hex2nix</link> in the future to automate the process.

<title>Icons</title>
<para>
When an application uses icons, an icon theme should be available in <envar>XDG_DATA_DIRS</envar>. The package for the default, icon-less <link xlink:href="https://www.freedesktop.org/wiki/Software/icon-theme/">hicolor-icon-theme</link> contains <link linkend="ssec-gnome-hooks-hicolor-icon-theme">a setup hook</link> that will pick up icon themes from <literal>buildInputs</literal> and pass it to our wrapper. Unfortunately, relying on that would mean every user has to download the theme included in the package expression no matter their preference. For that reason, we leave the installation of icon theme on the user. If you use one of the desktop environments, you probably already have an icon theme installed.
When an application uses icons, an icon theme should be available in <envar>XDG_DATA_DIRS</envar> during runtime. The package for the default, icon-less <link xlink:href="https://www.freedesktop.org/wiki/Software/icon-theme/">hicolor-icon-theme</link> (should be propagated by every icon theme) contains <link linkend="ssec-gnome-hooks-hicolor-icon-theme">a setup hook</link> that will pick up icon themes from <literal>buildInputs</literal> and pass it to our wrapper.

To avoid costly file system access when locating icons, GTK, <link xlink:href="https://woboq.com/blog/qicon-reads-gtk-icon-cache-in-qt57.html">as well as Qt</link>, can rely on <filename>icon-theme.cache</filename> files from the themes’ top-level directories. These files are generated using <command>gtk-update-icon-cache</command>, which is expected to be run whenever an icon is added or removed to an icon theme (typically an application icon into <literal>hicolor</literal> theme) and some programs do indeed run this after icon installation. However, since packages are installed into their own prefix by Nix, this would lead to conflicts. For that reason, <package>gtk3</package> provides a <link xlink:href="#ssec-gnome-hooks-gtk-drop-icon-theme-cache">setup hook</link> that will clean the file from installation. Since most applications only ship their own icon that will be loaded on start-up, it should not affect them too much. On the other hand, icon themes are much larger and more widely used so we need to cache them. Because we recommend installing icon themes globally, we will generate the cache files from all packages in a profile using a NixOS module. You can enable the cache generation using <option>gtk.iconCache.enable</option> option if your desktop environment does not already do that.

The function that builds the kernel has an argument <varname>kernelPatches</varname> which should be a list of <literal>{name, patch, extraConfig}</literal> attribute sets, where <varname>name</varname> is the name of the patch (which is included in the kernel’s <varname>meta.description</varname> attribute), <varname>patch</varname> is the patch itself (possibly compressed), and <varname>extraConfig</varname> (optional) is a string specifying extra options to be concatenated to the kernel configuration file (<filename>.config</filename>).
</para>
<para>
The kernel derivation exports an attribute <varname>features</varname> specifying whether optional functionality is or isn’t enabled. This is used in NixOS to implement kernel-specific behaviour. For instance, if the kernel has the <varname>iwlwifi</varname> feature (i.e. has built-in support for Intel wireless chipsets), then NixOS doesn’t have to build the external <varname>iwlwifi</varname> package:

It may be that the new kernel requires updating the external kernel modules and kernel-dependent packages listed in the <varname>linuxPackagesFor</varname> function in <filename>all-packages.nix</filename> (such as the NVIDIA drivers, AUFS, etc.).

<title>X.org</title>
<para>
The Nix expressions for the X.org packages reside in <filename>pkgs/servers/x11/xorg/default.nix</filename>. This file is automatically generated from lists of tarballs in an X.org release. As such it should not be modified directly; rather, you should modify the lists, the generator script or the file <filename>pkgs/servers/x11/xorg/overrides.nix</filename>, in which you can override or add to the derivations produced by the generator.
</para>
<para>
The generator is invoked as follows:
<screen>
<prompt>$ </prompt>cd pkgs/servers/x11/xorg
<prompt>$ </prompt>cat tarballs-7.5.list extra.list old.list \
| perl ./generate-expr-from-tarballs.pl
</screen>
For each of the tarballs in the <filename>.list</filename> files, the script downloads it, unpacks it, and searches its <filename>configure.ac</filename> and <filename>*.pc.in</filename> files for dependencies. This information is used to generate <filename>default.nix</filename>. The generator caches downloaded tarballs between runs. Pay close attention to the <literal>NOT FOUND: <replaceable>name</replaceable></literal> messages at the end of the run, since they may indicate missing dependencies. (Some might be optional dependencies, however.)
</para>
<para>
A file like <filename>tarballs-7.5.list</filename> contains all tarballs in a X.org release. It can be generated like this:
<screen>
<prompt>$ </prompt>export i="mirror://xorg/X11R7.4/src/everything/"
<prompt>$ </prompt>cat $(PRINT_PATH=1 nix-prefetch-url $i | tail -n 1) \
| perl -e 'while (&lt;>) { if (/(href|HREF)="([^"]*.bz2)"/) { print "$ENV{'i'}$2\n"; }; }' \
| sort > tarballs-7.4.list
</screen>
<filename>extra.list</filename> contains libraries that aren’t part of X.org proper, but are closely related to it, such as <literal>libxcb</literal>. <filename>old.list</filename> contains some packages that were removed from X.org, but are still needed by some people or by other packages (such as <varname>imake</varname>).
</para>
<para>

<para>
The Nix expressions related to the Eclipse platform and IDE are in <link xlink:href="https://github.com/NixOS/nixpkgs/blob/master/pkgs/applications/editors/eclipse"><filename>pkgs/applications/editors/eclipse</filename></link>.
</para>
<para>
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. 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.
</para>

Some packages provide the shell integration to be more useful. But unlike other systems, nix doesn't have a standard share directory location.

<section xml:id="sec-weechat">
<title>Weechat</title>
<para>
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
];
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 = "...";

<title>ETags on static files served from the Nix store</title>
<para>
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.

Packages that use OpenGL have NixOS desktop as their primary target.

If you are using a non-NixOS GNU/Linux/X11 desktop with free software video drivers, consider launching OpenGL-dependent programs from Nixpkgs with Nixpkgs versions of <literal>libglvnd</literal> and <literal>mesa_drivers</literal> in <literal>LD_LIBRARY_PATH</literal>.

<para>
To allow simultaneous use of packages linked against different versions of <literal>glibc</literal> with different locale archive formats Nixpkgs patches <literal>glibc</literal> to rely on <literal>LOCALE_ARCHIVE</literal> environment variable.
</para>
<para>
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. It is possible to build a custom set of locales by overriding parameters <literal>allLocales</literal> and <literal>locales</literal> of the package.

<title>Configuring Emacs</title>
<para>
The Emacs package comes with some extra helpers to make it easier to configure. <varname>emacsWithPackages</varname> allows you to manage packages from ELPA. This means that you will not have to install that packages from within Emacs. For instance, if you wanted to use <literal>company</literal>, <literal>counsel</literal>, <literal>flycheck</literal>, <literal>ivy</literal>, <literal>magit</literal>, <literal>projectile</literal>, and <literal>use-package</literal> you could use this as a <filename>~/.config/nixpkgs/config.nix</filename> override:

}
}
</screen>
<para>
You can install it like any other packages via <command>nix-env -iA myEmacs</command>. However, this will only install those packages. It will not <literal>configure</literal> them for us. To do this, we need to provide a configuration file. Luckily, it is possible to do this from within Nix! By modifying the above example, we can make Emacs load a custom config file. The key is to create a package that provide a <filename>default.el</filename> file in <filename>/share/emacs/site-start/</filename>. Emacs knows to load this file automatically when it starts.

# Introduction

The Nix Packages collection (Nixpkgs) is a set of thousands of packages for the
[Nix package manager](http://nixos.org/nix/), released under a
[Nix package manager](https://nixos.org/nix/), released under a
[permissive MIT/X11 license](https://github.com/NixOS/nixpkgs/blob/master/COPYING).
Packages are available for several platforms, and can be used with the Nix
package manager on most GNU/Linux distributions as well as NixOS.
package manager on most GNU/Linux distributions as well as [NixOS](https://nixos.org/nixos).
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
