+Contributing
+============
+
+Thanks for wanting to contribute to Home Manager! These are some
+guidelines to make the process as smooth as possible for both you and
+the Home Manager developers.
+
+If you are only looking to report a problem then it is sufficient to
+read through the following section on reporting issues. If you instead
+want to directly contribute improvements and additions then please
+have a look at everything here.
+
+Reporting an issue
+------------------
+
+If you notice a problem with Home Manager and want to report it then
+have a look among the already [open issues][], if you find one
+matching yours then feel free to comment on it to add any additional
+information you may have.
+
+If no matching issue exists then go to the [new issue][] page and
+write a description of your problem. Include as much information as
+you can, ideally also include relevant excerpts from your Home Manager
+configuration.
+
+Contributing code
+-----------------
+
+If you want to contribute code to improve Home Manager then please
+follow these guidelines.
+
+### Fork and create a pull request ###
+
+If you have not previously forked Home Manager then you need to do
+that first. Have a look at GitHub's "[Fork A Repo][]" for instructions
+on how to do this.
+
+Once you have a fork of Home Manager you should create a branch
+starting at the most recent `master`. Give your branch a reasonably
+descriptive name. Perform your changes on this branch and when you are
+happy with the result push the branch to GitHub and
+[create a pull request][].
+
+Assuming your clone is at `$HOME/devel/home-manager` then you can make
+the `home-manager` command use it by either
+
+1.  overriding the default path by using the `-I` command line option:
+
+        home-manager -I home-manager=$HOME/devel/home-manager
+
+    or
+
+2.  changing the default path by ensuring your configuration includes
+
+        programs.home-manager.enable = true;
+        programs.home-manager.path = "$HOME/devel/home-manager";
+
+    and running `home-manager switch` to activate the change.
+    Afterwards, `home-manager build` and `home-manager switch` will
+    use your cloned repository.
+
+The first option is good if you only temporarily want to use your
+clone.
+
+### Commits ###
+
+The commits in your pull request should be reasonably self-contained,
+that is, each commit should make sense in isolation. In particular,
+you will be asked to amend any commit that introduces syntax errors or
+similar problems even if they are fixed in a later commit.
+
+The commit messages should follow the format
+
+    {component}: {description}
+
+    {long description}
+
+where `{component}` refers to the code component (or module) your
+change affects, `{description}` is a brief description of your change,
+and `{long description}` is an optional clarifying description. Note,
+`{description}` should start with a lower case letter. As a rare
+exception, if there is no clear component, or your change affects many
+components, then the `{component}` part is optional.
+
+When adding a new module, say `foo.nix`, we use the fixed commit
+format `foo: add module`. You can, of course, still include a long
+description if you wish.
+
+In addition to the above commit message guidelines, try to follow the
+[seven rules][] as much as possible.
+
+### Style guidelines ###
+
+The code in Home Manager should follow the [Nixpkgs syntax
+guidelines][]. Note, we prefer `lowerCamelCase` for variable and
+attribute names with the accepted exception of variables directly
+referencing packages in Nixpkgs which use a hyphenated style. For
+example, the Home Manager option `services.gpg-agent.enableSshSupport`
+references the `gpg-agent` package in Nixpkgs.
+
+### News ###
+
+Home Manager includes a system for presenting news to the user. When
+making a change you, therefore, have the option to also include an
+associated news entry. In general, a news entry should only be added
+for truly noteworthy news. For example, a bug fix or new option does
+generally not need a news entry.
+
+If you do have a change worthy of a news entry then please add one in
+[`news.nix`][] but you should follow some basic guidelines:
+
+- The entry timestamp should be in ISO-8601 format having "+00:00" as
+  time zone. For example, "2017-09-13T17:10:14+00:00". A suitable
+  timestamp can be produced by the command
+
+      date --iso-8601=second --universal
+
+- The entry condition should be as specific as possible. For example,
+  if you are changing or deprecating a specific option then you could
+  restrict the news to those users who actually use this option.
+
+- Wrap the news message so that it will fit in the typical terminal,
+  that is, at most 80 characters wide. Ideally a bit less.
+
+- Unlike commit messages, news will be read without any connection to
+  the Home Manager source code. It is therefore important to make the
+  message understandable in isolation and to those who do not have
+  knowledge of the Home Manager internals. To this end it should be
+  written in more descriptive, prose like way.
+
+- If you refer to an option then write its full attribute path. That
+  is, instead of writing
+
+  > The option 'foo' has been deprecated, please use 'bar' instead.
+
+  it should read
+
+  > The option 'services.myservice.foo' has been deprecated, please
+  > use 'services.myservice.bar' instead.
+
+- A new module, say `foo.nix`, should always include a news entry
+  (without any condition) that has a message along the lines of
+
+  > A new service is available: 'services.foo'.
+
+  or
+
+  > A new program configuration is available: 'program.foo'.
+
+  depending on the type of module.

+Frequently Asked Questions (FAQ)
+================================
+
+Why is there a collision error when switching generation?
+---------------------------------------------------------
+
+Home Manager currently installs packages into the user environment,
+precisely as if the packages were installed through
+`nix-env --install`. This means that you will get a collision error if
+your Home Manager configuration attempts to install a package that you
+already have installed manually, that is, packages that shows up when
+you run `nix-env --query`.
+
+For example, imagine you have the `hello` package installed in your
+environment
+
+```console
+$ nix-env --query
+hello-2.10
+```
+
+and your Home Manager configuration contains
+
+    home.packages = [ pkgs.hello ];
+
+Then attempting to switch to this configuration will result in an
+error similar to
+
+```console
+$ home-manager switch
+these derivations will be built:
+  /nix/store/xg69wsnd1rp8xgs9qfsjal017nf0ldhm-home-manager-path.drv
+[…]
+Activating installPackages
+replacing old ‘home-manager-path’
+installing ‘home-manager-path’
+building path(s) ‘/nix/store/b5c0asjz9f06l52l9812w6k39ifr49jj-user-environment’
+Wide character in die at /nix/store/64jc9gd2rkbgdb4yjx3nrgc91bpjj5ky-buildenv.pl line 79.
+collision between ‘/nix/store/fmwa4axzghz11cnln5absh31nbhs9lq1-home-manager-path/bin/hello’ and ‘/nix/store/c2wyl8b9p4afivpcz8jplc9kis8rj36d-hello-2.10/bin/hello’; use ‘nix-env --set-flag priority NUMBER PKGNAME’ to change the priority of one of the conflicting packages
+builder for ‘/nix/store/b37x3s7pzxbasfqhaca5dqbf3pjjw0ip-user-environment.drv’ failed with exit code 2
+error: build of ‘/nix/store/b37x3s7pzxbasfqhaca5dqbf3pjjw0ip-user-environment.drv’ failed
+```
+
+The solution is typically to uninstall the package from the
+environment using `nix-env --uninstall` and reattempt the Home Manager
+generation switch.
+
+Why are the session variables not set?
+--------------------------------------
+
+Home Manager is only able to set session variables automatically if it
+manages your Bash or Z shell configuration. If you don't want to let
+Home Manager manage your shell then you will have to manually source
+the
+
+    ~/.nix-profile/etc/profile.d/hm-session-vars.sh
+
+file in an appropriate way. In Bash and Z shell this can be done by
+adding
+
+```sh
+. "$HOME/.nix-profile/etc/profile.d/hm-session-vars.sh"
+```
+
+to your `.profile` and `.zshrc` files, respectively. The
+`hm-session-vars.sh` file should work in most Bourne-like shells.
+
+How do set up a configuration for multiple users/machines?
+----------------------------------------------------------
+
+A typical way to prepare a repository of configurations for multiple
+logins and machines is to prepare one "top-level" file for each unique
+combination.
+
+For example, if you have two machines, called "kronos" and "rhea" on
+which you want to configure your user "jane" then you could create the
+files
+
+- `kronos-jane.nix`,
+- `rhea-jane.nix`, and
+- `common.nix`
+
+in your repository. On the kronos and rhea machines you can then make
+`~jane/.config/nixpkgs/home.nix` be a symbolic link to the
+corresponding file in your configuration repository.
+
+The `kronos-jane.nix` and `rhea-jane.nix` files follow the format
+
+```nix
+{ ... }:
+
+{
+  imports = [ ./common.nix ];
+
+  # Various options that are specific for this machine/user.
+}
+```
+
+while the `common.nix` file contains configuration shared across the
+two logins. Of course, instead of just a single `common.nix` file you
+can have multiple ones, even one per program or service.
+
+You can get some inspiration from the [Post your home-manager home.nix
+file!][1] Reddit thread.
+
+[1]: https://www.reddit.com/r/NixOS/comments/9bb9h9/post_your_homemanager_homenix_file/
+
+Why do I get an error message about `ca.desrt.dconf`?
+-----------------------------------------------------
+
+You are most likely trying to configure the GTK or Gnome Terminal but
+the DBus session is not aware of the dconf service. The full error you
+might get is
+
+    error: GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name ca.desrt.dconf was not provided by any .service files
+
+The solution on NixOS is to add
+
+    services.dbus.packages = with pkgs; [ gnome3.dconf ];
+
+to your system configuration.

+Home Manager using Nix
+======================
+
+This project provides a basic system for managing a user environment
+using the [Nix][] package manager together with the Nix libraries
+found in [Nixpkgs][]. Before attempting to use Home Manager please
+read the warning below.
+
+Words of warning
+----------------
+
+This project is under development. I personally use it to manage
+several user configurations but it may fail catastrophically for you.
+So beware!
+
+In some cases Home Manager cannot detect whether it will overwrite a
+previous manual configuration. For example, the Gnome Terminal module
+will write to your dconf store and cannot tell whether a configuration
+that it is about to be overwrite was from a previous Home Manager
+generation or from manual configuration.
+
+Home Manager targets [NixOS][] unstable and NixOS version 19.03 (the
+current stable version), it may or may not work on other Linux
+distributions and NixOS versions.
+
+Also, the `home-manager` tool does not explicitly support rollbacks at
+the moment so if your home directory gets messed up you'll have to fix
+it yourself. See the [rollbacks](#rollbacks) section for instructions
+on how to manually perform a rollback.
+
+Now when your expectations have been built up and you are eager to try
+all this out you can go ahead and read the rest of this text.
+
+Contact
+-------
+
+You can chat with us on IRC in the channel [#home-manager][] on
+[freenode][]. The [channel logs][] are hosted courtesy of
+[samueldr][].
+
+Installation
+------------
+
+Currently the easiest way to install Home Manager is as follows:
+
+1.  Make sure you have a working Nix installation. If you are not
+    using NixOS then you may here have to run
+
+    ```console
+    $ mkdir -m 0755 -p /nix/var/nix/{profiles,gcroots}/per-user/$USER
+    ```
+
+    since Home Manager uses these directories to manage your profile
+    generations. On NixOS these should already be available.
+
+    Also make sure that your user is able to build and install Nix
+    packages. For example, you should be able to successfully run a
+    command like `nix-instantiate '<nixpkgs>' -A hello` without having
+    to switch to the root user. For a multi-user install of Nix this
+    means that your user must be covered by the
+    [`allowed-users`][nixAllowedUsers] Nix option. On NixOS you can
+    control this option using the
+    [`nix.allowedUsers`][nixosAllowedUsers] system option.
+
+2.  Add the appropriate Home Manager channel. Typically this is
+
+    ```console
+    $ nix-channel --add https://github.com/rycee/home-manager/archive/master.tar.gz home-manager
+    $ nix-channel --update
+    ```
+
+    if you are following Nixpkgs master or an unstable channel and
+
+    ```console
+    $ nix-channel --add https://github.com/rycee/home-manager/archive/release-19.03.tar.gz home-manager
+    $ nix-channel --update
+    ```
+
+    if you follow a Nixpkgs version 19.03 channel.
+
+    On NixOS you may need to log out and back in for the channel to
+    become available. On non-NixOS you may have to add
+
+    ```shell
+    export NIX_PATH=$HOME/.nix-defexpr/channels${NIX_PATH:+:}$NIX_PATH
+    ```
+
+    to your shell (see [nix#2033](https://github.com/NixOS/nix/issues/2033)).
+
+3.  Install Home Manager and create the first Home Manager generation:
+
+    ```console
+    $ nix-shell '<home-manager>' -A install
+    ```
+
+    Once finished, Home Manager should be active and available in your
+    user environment.
+
+3.  If you do not plan on having Home Manager manage your shell
+    configuration then you must source the
+
+    ```
+    $HOME/.nix-profile/etc/profile.d/hm-session-vars.sh
+    ```
+
+    file in your shell configuration. Unfortunately, in this specific
+    case we currently only support POSIX.2-like shells such as
+    [Bash][] or [Z shell][].
+
+    For example, if you use Bash then add
+
+    ```bash
+    . "$HOME/.nix-profile/etc/profile.d/hm-session-vars.sh"
+    ```
+
+    to your `~/.profile` file.
+
+If instead of using channels you want to run Home Manager from a Git
+checkout of the repository then you can use the
+`programs.home-manager.path` option to specify the absolute path to
+the repository.
+
+Usage
+-----
+
+Home Manager is typically managed through the `home-manager` tool.
+This tool can, for example, apply configurations to your home
+directory, list user packages installed by the tool, and list the
+configuration generations.
+
+As an example, let us expand the initial configuration file from the
+installation above to install the htop and fortune packages, install
+Emacs with a few extra packages enabled, install Firefox with the
+IcedTea plugin enabled, and enable the user gpg-agent service.
+
+To satisfy the above setup we should elaborate the
+`~/.config/nixpkgs/home.nix` file as follows:
+
+```nix
+{ pkgs, ... }:
+
+{
+  home.packages = [
+    pkgs.htop
+    pkgs.fortune
+  ];
+
+  programs.emacs = {
+    enable = true;
+    extraPackages = epkgs: [
+      epkgs.nix-mode
+      epkgs.magit
+    ];
+  };
+
+  programs.firefox = {
+    enable = true;
+    enableIcedTea = true;
+  };
+
+  services.gpg-agent = {
+    enable = true;
+    defaultCacheTtl = 1800;
+    enableSshSupport = true;
+  };
+
+  programs.home-manager = {
+    enable = true;
+    path = "…";
+  };
+}
+```
+
+To activate this configuration you can then run
+
+```console
+$ home-manager switch
+```
+
+or if you are not feeling so lucky,
+
+```console
+$ home-manager build
+```
+
+which will create a `result` link to a directory containing an
+activation script and the generated home directory files.
+
+Documentation of available configuration options, including
+descriptions and usage examples, is available in the [Home Manager
+manual][configuration options] or offline by running
+
+```console
+$ man home-configuration.nix
+```
+
+Rollbacks
+---------
+
+While the `home-manager` tool does not explicitly support rollbacks at
+the moment it is relatively easy to perform one manually. The steps to
+do so are
+
+1.  Run `home-manager generations` to determine which generation you
+    wish to rollback to:
+
+    ```console
+    $ home-manager generations
+    2018-01-04 11:56 : id 765 -> /nix/store/kahm1rxk77mnvd2l8pfvd4jkkffk5ijk-home-manager-generation
+    2018-01-03 10:29 : id 764 -> /nix/store/2wsmsliqr5yynqkdyjzb1y57pr5q2lsj-home-manager-generation
+    2018-01-01 12:21 : id 763 -> /nix/store/mv960kl9chn2lal5q8lnqdp1ygxngcd1-home-manager-generation
+    2017-12-29 21:03 : id 762 -> /nix/store/6c0k1r03fxckql4vgqcn9ccb616ynb94-home-manager-generation
+    2017-12-25 18:51 : id 761 -> /nix/store/czc5y6vi1rvnkfv83cs3rn84jarcgsgh-home-manager-generation
+    …
+    ```
+
+2.  Copy the Nix store path of the generation you chose, e.g.,
+
+        /nix/store/mv960kl9chn2lal5q8lnqdp1ygxngcd1-home-manager-generation
+
+    for generation 763.
+
+3.  Run the `activate` script inside the copied store path:
+
+    ```console
+    $ /nix/store/mv960kl9chn2lal5q8lnqdp1ygxngcd1-home-manager-generation/activate
+    Starting home manager activation
+    …
+    ```
+
+Keeping your ~ safe from harm
+-----------------------------
+
+To configure programs and services Home Manager must write various
+things to your home directory. To prevent overwriting any existing
+files when switching to a new generation, Home Manager will attempt to
+detect collisions between existing files and generated files. If any
+such collision is detected the activation will terminate before
+changing anything on your computer.
+
+For example, suppose you have a wonderful, painstakingly created
+`~/.config/git/config` and add
+
+```nix
+{
+  # …
+
+  programs.git = {
+    enable = true;
+    userName = "Jane Doe";
+    userEmail = "jane.doe@example.org";
+  };
+
+  # …
+}
+```
+
+to your configuration. Attempting to switch to the generation will
+then result in
+
+```console
+$ home-manager switch
+…
+Activating checkLinkTargets
+Existing file '/home/jdoe/.gitconfig' is in the way
+Please move the above files and try again
+```
+
+Graphical services
+------------------
+
+Home Manager includes a number of services intended to run in a

+Unfortunately, such services will not be started automatically unless

+

+  Home Manager can be used in three primary ways:

+   <listitem>
+    <para>
+     Using the standalone <command>home-manager</command> tool. For platforms
+     other than NixOS and Darwin, this is the only available choice. It is also
+     recommended for people on NixOS or Darwin that want to manage their home
+     directory independent of the system as a whole. See
+     <xref linkend="sec-install-standalone"/> for instructions on how to
+     perform this installation.
+    </para>
+   </listitem>
+   <listitem>
+    <para>
+     As a module within a NixOS system configuration. This allows the user
+     profiles to be built together with the system when running
+     <command>nixos-rebuild</command>. See
+     <xref linkend="sec-install-nixos-module"/> for a description of this

+</screen>

+     since Home Manager uses these directories to manage your profile
+     generations. On NixOS these should already be available.
+    </para>
+    <para>
+     Also make sure that your user is able to build and install Nix packages.
+     For example, you should be able to successfully run a command like
+     <literal>nix-instantiate '&lt;nixpkgs&gt;' -A hello</literal> without
+     having to switch to the root user. For a multi-user install of Nix this
+     means that your user must be covered by the
+     <link xlink:href="https://nixos.org/nix/manual/#conf-allowed-users"><literal>allowed-users</literal></link>
+     Nix option. On NixOS you can control this option using the

+</programlisting>
+     to your shell (see

+== Release 19.03
+
+The 19.03 release branch became the stable branch in April, 2019.
+
+[[sec-release-19.03-highlights]]
+=== Highlights
+:opt-home-file-source: opt-home.file._name__.source
+
+This release has the following notable changes:
+
+* The <<{opt-home-file-source}>> option now allows source files to be
+hidden, that is, having a name starting with the `.` character. It
+also allows the source file name to contain characters not typically
+allowed for Nix store paths. For example, your configuration can now
+contain things such as
++
+[source,nix]
+----
+home.file."my file".source = ./. + "/file with spaces!";
+----
+
+* The type used for the systemd unit options under
+<<opt-systemd.user.services>>, <<opt-systemd.user.sockets>>, etc. has
+been changed to offer more robust merging of configurations. If you
+don't override values within systemd units then you are not affected
+by this change. Unfortunately, if you do override unit values you may
+encounter errors.
++
+In particular, if you get an error saying that a ``unique option'' is
+``defined multiple times'' then you need to use the
+https://nixos.org/nixos/manual/#sec-option-definitions-setting-priorities[`mkForce`]
+function. For example,
++
+[source,nix]
+----
+systemd.user.services.foo.Service.ExecStart = "/foo/bar";
+----
++
+becomes
++
+[source,nix]
+----
+systemd.user.services.foo.Service.ExecStart = lib.mkForce "/foo/bar";
+----
++
+We had to make this change because the old merging was causing too
+many confusing situations for people.
+
+[[sec-release-19.03-state-version-changes]]
+=== State Version Changes
+
+The state version in this release includes the changes below. These
+changes are only active if the <<opt-home.stateVersion>> option is set
+to ``19.03'' or later.
+
+* There is now an option <<opt-programs.beets.enable>> that defaults
+to `false`. Before the module would be active if the
+<<opt-programs.beets.settings>> option was non-empty.

+
+The state version in this release includes the changes below. These
+changes are only active if the `home.stateVersion` option is set to
+"19.09" or later.
+
+* The <<opt-programs.firefox.package>> option now expects a wrapped
+  Firefox package and defaults to `pkgs.firefox`.
+
+* The options <<opt-home.keyboard.layout>> and
+  <<opt-home.keyboard.variant>> now default to `null`, which indicates
+  that the system value should be used.

+# OSX won't update Bash 3 (last updated circa 2009) to Bash 4,

+#
+# For example, OSX Yosemite (released circa 2014) ships with Bash 3:

+#  $ echo $BASH_VERSION
+#  3.2
+#
+# While Ubuntu LTS 14.04 (a.k.a. Trusty, also released circa 2016)
+# ships with the latest version, Bash 4 (updated circa 2016):
+#
+#  $ echo $BASH_VERSION
+#  4.3
+#
+
+# Testing
+#
+# (1) Invoke « shellcheck »
+#
+#     * source: « https://github.com/koalaman/shellcheck »
+#     * run:    « shellcheck ./share/bash-completion/completions/home-manager »

+          It is now possible to use Home Manager as a NixOS module.
+          This allows you to prepare user environments from the system

+          using the 'home-manager' tool. It also opens up additional
+          possibilities, for example, to automatically configure user
+          environments in NixOS declarative containers or on systems
+          deployed through NixOps.
+
+          This feature should be considered experimental for now and
+          some critial limitations apply. For example, it is currently
+          not possible to use 'nixos-rebuild build-vm' when using the
+          Home Manager NixOS module. That said, it should be
+          reasonably robust and stable for simpler use cases.
+
+          To make Home Manager available in your NixOS system
+          configuration you can add
+
+              imports = [
+                "''${builtins.fetchTarball https://github.com/rycee/home-manager/archive/master.tar.gz}/nixos"

+
+          to your 'configuration.nix' file. This will introduce a new
+          NixOS option called 'home-manager.users' whose type is an
+          attribute set mapping user names to Home Manager
+          configurations.
+
+          For example, a NixOS configuration may include the lines
+
+              users.users.eve.isNormalUser = true;
+              home-manager.users.eve = {
+                home.packages = [ pkgs.atool pkgs.httpie ];

+              };
+
+          and after a 'nixos-rebuild switch' the user eve's
+          environment should include a basic Bash configuration and
+          the packages atool and httpie.
+

+# the `info` command (and the Info subsystem within Emacs) gives easy
+# access to the info files stored system-wide, but not info files in
+# your ~/.nix-profile.
+
+# We set $INFOPATH to include `/run/current-system/sw/share/info` and
+# `~/.nix-profile/share/info` but it's not enough. Although info can
+# then find files when you explicitly ask for them, it doesn't show
+# them to you in the table of contents on startup. To do that requires
+# a `dir` file. NixOS keeps the system-wide `dir` file up to date, but
+# ignores home-installed packages.
+
+# So this module contains an activation script that generates the
+# `dir` for your home profile. Then when you start info (and both
+# `dir` files are in your $INFOPATH), it will *merge* the contents of
+# the two files, showing you a unified table of contents for all
+# packages. This is really nice.
