-  This has been automatically marked as stale because it has had no activity for 180 days.
+    Nixpkgs is a busy repository, and unfortunately sometimes PRs get left behind for too long. Nevertheless, we'd like to help committers reach the PRs that are still important. This PR has had no activity for 180 days, and so I marked it as stale, but you can rest assured it will never be closed by a non-human.
 
-  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.
+    If this is still important to you and you'd like to remove the stale label, we ask that you leave a comment. Your comment can be as simple as "still important to me".  But there's a bit more you can do:
 
-  Here are suggestions that might help resolve this more quickly:
+    If you received an approval by an unprivileged maintainer and you are just waiting for a merge, you can @ mention someone with merge permissions and ask them to help. You might be able to find someone relevant by using [Git blame](https://git-scm.com/docs/git-blame) on the relevant files, or via [GitHub's web interface](https://docs.github.com/en/github/managing-files-in-a-repository/tracking-changes-in-a-file). You can see if someone's a member of the [nixpkgs-committers](https://github.com/orgs/NixOS/teams/nixpkgs-committers) team, by hovering with the mouse over their username on the web interface, or by searching them directly on [the list](https://github.com/orgs/NixOS/teams/nixpkgs-committers).
+
+    If your PR wasn't reviewed at all, it might help to find someone who's perhaps a user of the package or module you are changing, or alternatively, ask once more for a review by the maintainer of the package/module this is about. If you don't know any, you can use [Git blame](https://git-scm.com/docs/git-blame) on the relevant files, or [GitHub's web interface](https://docs.github.com/en/github/managing-files-in-a-repository/tracking-changes-in-a-file) to find someone who touched the relevant files in the past.
+
+    If your PR has had reviews and nevertheless got stale, make sure you've responded to all of the reviewer's requests / questions. Usually when PR authors show responsibility and dedication, reviewers (privileged or not) show dedication as well. If you've pushed a change, it's possible the reviewer wasn't notified about your push via email, so you can always [officially request them for a review](https://docs.github.com/en/github/collaborating-with-issues-and-pull-requests/requesting-a-pull-request-review), or just @ mention them and say you've addressed their comments.
+
+    Lastly, you can always ask for help at [our Discourse Forum](https://discourse.nixos.org/), or more specifically, [at this thread](https://discourse.nixos.org/t/prs-in-distress/3604) or at [#nixos' IRC channel](https://webchat.freenode.net/#nixos).

Most Perl packages are so straight-forward to build that they are defined here directly, rather than having a separate function for each package called from <filename>perl-packages.nix</filename>. However, more complicated packages should be put in a separate file, typically in <filename>pkgs/development/perl-modules</filename>. Here is an example of the former:
-<programlisting>
-ClassC3 = buildPerlPackage rec {
-  name = "Class-C3-0.21";
-  src = fetchurl {
-    url = "mirror://cpan/authors/id/F/FL/FLORA/${name}.tar.gz";

-  };
-};
-</programlisting>
-  Note the use of <literal>mirror://cpan/</literal>, and the <literal>${name}</literal> in the URL definition to ensure that the name attribute is consistent with the source that we’re actually downloading. Perl packages are made available in <filename>all-packages.nix</filename> through the variable <varname>perlPackages</varname>. For instance, if you have a package that needs <varname>ClassC3</varname>, you would typically write
-<programlisting>
-foo = import ../path/to/foo.nix {
-  inherit stdenv fetchurl ...;
-  inherit (perlPackages) ClassC3;
-};
-</programlisting>
-  in <filename>all-packages.nix</filename>. You can test building a Perl package as follows:
-<screen>
-<prompt>$ </prompt>nix-build -A perlPackages.ClassC3
-</screen>
-  <varname>buildPerlPackage</varname> adds <literal>perl-</literal> to the start of the name attribute, so the package above is actually called <literal>perl-Class-C3-0.21</literal>. So to install it, you can say:
-<screen>
-<prompt>$ </prompt>nix-env -i perl-Class-C3
-</screen>
-  (Of course you can also install using the attribute name: <literal>nix-env -i -A perlPackages.ClassC3</literal>.)
- </para>
-
- <para>
-  So what does <varname>buildPerlPackage</varname> do? It does the following:
-  <orderedlist>
-   <listitem>
-    <para>
-     In the configure phase, it calls <literal>perl Makefile.PL</literal> to generate a Makefile. You can set the variable <varname>makeMakerFlags</varname> to pass flags to <filename>Makefile.PL</filename>
-    </para>
-   </listitem>
-   <listitem>
-    <para>
-     It adds the contents of the <envar>PERL5LIB</envar> environment variable to <literal>#! .../bin/perl</literal> line of Perl scripts as <literal>-I<replaceable>dir</replaceable></literal> flags. This ensures that a script can find its dependencies. (This can cause this shebang line to become too long for Darwin to handle; see the note below.)
-    </para>
-   </listitem>
-   <listitem>
-    <para>
-     In the fixup phase, it writes the propagated build inputs (<varname>propagatedBuildInputs</varname>) to the file <filename>$out/nix-support/propagated-user-env-packages</filename>. <command>nix-env</command> recursively installs all packages listed in this file when you install a package that has it. This ensures that a Perl package can find its dependencies.
-    </para>
-   </listitem>
-  </orderedlist>
- </para>
-
- <para>
-  <varname>buildPerlPackage</varname> is built on top of <varname>stdenv</varname>, so everything can be customised in the usual way. For instance, the <literal>BerkeleyDB</literal> module has a <varname>preConfigure</varname> hook to generate a configuration file used by <filename>Makefile.PL</filename>:
-<programlisting>
-{ buildPerlPackage, fetchurl, db }:
-

- <para>
-  Dependencies on other Perl packages can be specified in the <varname>buildInputs</varname> and <varname>propagatedBuildInputs</varname> attributes. If something is exclusively a build-time dependency, use <varname>buildInputs</varname>; if it’s (also) a runtime dependency, use <varname>propagatedBuildInputs</varname>. For instance, this builds a Perl module that has runtime dependencies on a bunch of other modules:
-<programlisting>
-ClassC3Componentised = buildPerlPackage rec {
-  name = "Class-C3-Componentised-1.0004";
-  src = fetchurl {

-  propagatedBuildInputs = [

-  ];
-};
-</programlisting>
- </para>
-
- <para>
-  On Darwin, if a script has too many <literal>-I<replaceable>dir</replaceable></literal> flags in its first line (its “shebang line”), it will not run. This can be worked around by calling the <literal>shortenPerlShebang</literal> function from the <literal>postInstall</literal> phase:
-<programlisting>
-{ stdenv, buildPerlPackage, fetchurl, shortenPerlShebang }:
-
-ImageExifTool = buildPerlPackage {

-
-  src = fetchurl {

-    sha256 = "0d8v48y94z8maxkmw1rv7v9m0jg2dc8xbp581njb6yhr7abwqdv3";

-
-  buildInputs = stdenv.lib.optional stdenv.isDarwin shortenPerlShebang;
-  postInstall = stdenv.lib.optional stdenv.isDarwin ''
-    shortenPerlShebang $out/bin/exiftool
-  '';
-};
-</programlisting>
-  This will remove the <literal>-I</literal> flags from the shebang line, rewrite them in the <literal>use lib</literal> form, and put them on the next line instead. This function can be given any number of Perl scripts as arguments; it will modify them in-place.

   <para>
-   Nix expressions for Perl packages can be generated (almost) automatically from CPAN. This is done by the program <command>nix-generate-from-cpan</command>, which can be installed as follows:
+   When executing a Perl script, it is possible you get an error such as <literal>./myscript.pl: bad interpreter: /usr/bin/perl: no such file or directory</literal>. This happens when the script expects Perl to be installed at <filename>/usr/bin/perl</filename>, which is not the case when using Perl from nixpkgs. You can fix the script by changing the first line to:
+  <programlisting>
+  #!/usr/bin/env perl

-<screen>
+  <para>
-<prompt>$ </prompt>nix-env -i nix-generate-from-cpan
+   When the script is using a Perl library that is not installed globally, you might get an error such as <literal>Can't locate DB_File.pm in @INC (you may need to install the DB_File module)</literal>. In that case, you can use <command>nix-shell</command> to start an ad-hoc shell with that library installed, for instance:

+   Dependencies on other Perl packages can be specified in the <varname>buildInputs</varname> and <varname>propagatedBuildInputs</varname> attributes. If something is exclusively a build-time dependency, use <varname>buildInputs</varname>; if it’s (also) a runtime dependency, use <varname>propagatedBuildInputs</varname>. For instance, this builds a Perl module that has runtime dependencies on a bunch of other modules:
+ <programlisting>

+
+  <para>
+   On Darwin, if a script has too many <literal>-I<replaceable>dir</replaceable></literal> flags in its first line (its “shebang line”), it will not run. This can be worked around by calling the <literal>shortenPerlShebang</literal> function from the <literal>postInstall</literal> phase:
+ <programlisting>
+ { stdenv, buildPerlPackage, fetchurl, shortenPerlShebang }:
+
+ ImageExifTool = buildPerlPackage {
+   pname = "Image-ExifTool";
+   version = "11.50";
+
+   src = fetchurl {
+     url = "https://www.sno.phy.queensu.ca/~phil/exiftool/Image-ExifTool-11.50.tar.gz";
+     sha256 = "0d8v48y94z8maxkmw1rv7v9m0jg2dc8xbp581njb6yhr7abwqdv3";
+   };
+
+   buildInputs = stdenv.lib.optional stdenv.isDarwin shortenPerlShebang;
+   postInstall = stdenv.lib.optional stdenv.isDarwin ''
+     shortenPerlShebang $out/bin/exiftool
+   '';
+ };
+ </programlisting>
+   This will remove the <literal>-I</literal> flags from the shebang line, rewrite them in the <literal>use lib</literal> form, and put them on the next line instead. This function can be given any number of Perl scripts as arguments; it will modify them in-place.

+    Nixpkgs has experimental support for cross-compiling Perl modules. In many cases, it will just work out of the box, even for modules with native extensions. Sometimes, however, the Makefile.PL for a module may (indirectly) import a native module. In that case, you will need to make a stub for that module that will satisfy the Makefile.PL and install it into <filename>lib/perl5/site_perl/cross_perl/${perl.version}</filename>. See the <varname>postInstall</varname> for <varname>DBI</varname> for an example.

+    NixOS provides various APIs that benefit from GPU hardware
+    acceleration, such as VA-API and VDPAU for video playback; OpenGL and
+    Vulkan for 3D graphics; and OpenCL for general-purpose computing.
+    This chapter describes how to set up GPU hardware acceleration (as far
+    as this is not done automatically) and how to verify that hardware
+    acceleration is indeed used.
+  </para>
+
+  <para>
+    Most of the aforementioned APIs are agnostic with regards to which
+    display server is used. Consequently, these instructions should apply
+    both to the X Window System and Wayland compositors.

+      OpenCL applications load drivers through the <emphasis>Installable Client
+      Driver</emphasis> (ICD) mechanism. In this mechanism, an ICD file
+      specifies the path to the OpenCL driver for a particular GPU family.
+      In NixOS, there are two ways to make ICD files visible to the ICD
+      loader. The first is through the <varname>OCL_ICD_VENDORS</varname>
+      environment variable. This variable can contain a directory which
+      is scanned by the ICL loader for ICD files. For example:
+
+      <screen><prompt>$</prompt> export \
+  OCL_ICD_VENDORS=`nix-build '&lt;nixpkgs&gt;' --no-out-link -A rocm-opencl-icd`/etc/OpenCL/vendors/</screen>
+    </para>
+
+    <para>
+      The second mechanism is to add the OpenCL driver package to
+      <xref linkend="opt-hardware.opengl.extraPackages"/>. This links the
+      ICD file under <filename>/run/opengl-driver</filename>, where it will
+      be visible to the ICD loader.
+    </para>

+    <para>

+  Microsoft Onedrive is a popular cloud file-hosting service, used by 85% of Fortune 500 companies. NixOS uses a popular OneDrive client for Linux maintained by github user abraunegg. The Linux client is excellent and allows customization of which files or paths to download, not much unlike the default Windows OneDrive client by Microsoft itself. The client allows syncing with multiple onedrive accounts at the same time, of any type- OneDrive personal, OneDrive business, Office365 and Sharepoint libraries, without any additional charge.

+  For more information, guides and documentation, see <link xlink:href="https://abraunegg.github.io/"/>.

+  To enable OneDrive support, add the following to your <filename>configuration.nix</filename>:
+<programlisting>
+<xref linkend="opt-services.onedrive.enable"/> = true;
+</programlisting>
+  This installs the <literal>onedrive</literal> package and a service <literal>onedriveLauncher</literal> which will instantiate a <literal>onedrive</literal> service for all your OneDrive accounts. Follow the steps in documentation of the onedrive client to setup your accounts. To use the service with multiple accounts, create a file named <filename>onedrive-launcher</filename> in <filename>~/.config</filename> and add the filename of the config directory, relative to <filename>~/.config</filename>. For example, if you have two OneDrive accounts with configs in <filename>~/.config/onedrive_bob_work</filename> and <filename>~/.config/onedrive_bob_personal</filename>, add the following lines:
+<programlisting>
+onedrive_bob_work
+# Not in use:
+# onedrive_bob_office365
+onedrive_bob_personal
+</programlisting>
+  No such file needs to be created if you are using only a single OneDrive account with config in the default location <filename>~/.config/onedrive</filename>, in the absence of <filename>~/.config/onedrive-launcher</filename>, only a single service is instantiated, with default config path.
