You should know how to make a +patch and an interdiff using git. It's fine to develop on github or +what-have-you, but eventually it has to be a patch that can be reviewed in the +normal Drupal issue process. See the list of resources for some information on +how to do do this. + +Your patch will also need to be reviewed by someone other than yourself. Learn +about the review process in the resources section. + +### DrupalCI + +Examples uses the Drupal automated testing system to verify the applicability of +patches. See `TESTING.md` for details. + +### Drupal coding standards + +All code in Examples should adhere to the Drupal core coding standards.

By contrast, the GNU General Public +License is intended to guarantee your freedom to share and change free +software--to make sure the software is free for all its users. This +General Public License applies to most of the Free Software +Foundation's software and to any other program whose authors commit to +using it. (Some other Free Software Foundation software is covered by +the GNU Lesser General Public License instead.) You can apply it to +your programs, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +this service if you wish), that you receive source code or can get it +if you want it, that you can change the software or use pieces of it +in new free programs; and that you know you can do these things. + + To protect your rights, we need to make restrictions that forbid +anyone to deny you these rights or to ask you to surrender the rights. +These restrictions translate to certain responsibilities for you if you +distribute copies of the software, or if you modify it. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must give the recipients all the rights that +you have. You must make sure that they, too, receive or can get the +source code. And you must show them these terms so they know their +rights. + + We protect your rights with two steps: (1) copyright the software, and +(2) offer you this license which gives you legal permission to copy, +distribute and/or modify the software. + + Also, for each author's protection and ours, we want to make certain +that everyone understands that there is no warranty for this free +software. If the software is modified by someone else and passed on, we +want its recipients to know that what they have is not the original, so +that any problems introduced by others will not reflect on the original +authors' reputations. + + Finally, any free program is threatened constantly by software +patents. We wish to avoid the danger that redistributors of a free +program will individually obtain patent licenses, in effect making the +program proprietary. To prevent this, we have made it clear that any +patent must be licensed for everyone's free use or not licensed at all. + + The precise terms and conditions for copying, distribution and +modification follow. + + GNU GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License applies to any program or other work which contains +a notice placed by the copyright holder saying it may be distributed +under the terms of this General Public License. The "Program", below, +refers to any such program or work, and a "work based on the Program" +means either the Program or any derivative work under copyright law: +that is to say, a work containing the Program or a portion of it, +either verbatim or with modifications and/or translated into another +language. (Hereinafter, translation is included without limitation in +the term "modification".) Each licensee is addressed as "you". + +Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running the Program is not restricted, and the output from the Program +is covered only if its contents constitute a work based on the +Program (independent of having been made by running the Program). +Whether that is true depends on what the Program does. + + 1. You may copy and distribute verbatim copies of the Program's +source code as you receive it, in any medium, provided that you +conspicuously and appropriately publish on each copy an appropriate +copyright notice and disclaimer of warranty; keep intact all the +notices that refer to this License and to the absence of any warranty; +and give any other recipients of the Program a copy of this License +along with the Program. + +You may charge a fee for the physical act of transferring a copy, and +you may at your option offer warranty protection in exchange for a fee. + + 2. You may modify your copy or copies of the Program or any portion +of it, thus forming a work based on the Program, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) You must cause the modified files to carry prominent notices + stating that you changed the files and the date of any change. + + b) You must cause any work that you distribute or publish, that in + whole or in part contains or is derived from the Program or any + part thereof, to be licensed as a whole at no charge to all third + parties under the terms of this License. + + c) If the modified program normally reads commands interactively + when run, you must cause it, when started running for such + interactive use in the most ordinary way, to print or display an + announcement including an appropriate copyright notice and a + notice that there is no warranty (or else, saying that you provide + a warranty) and that users may redistribute the program under + these conditions, and telling the user how to view a copy of this + License. (Exception: if the Program itself is interactive but + does not normally print such an announcement, your work based on + the Program is not required to print an announcement.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Program, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Program, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Program. + +In addition, mere aggregation of another work not based on the Program +with the Program (or with a work based on the Program) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may copy and distribute the Program (or a work based on it, +under Section 2) in object code or executable form under the terms of +Sections 1 and 2 above provided that you also do one of the following: + + a) Accompany it with the complete corresponding machine-readable + source code, which must be distributed under the terms of Sections + 1 and 2 above on a medium customarily used for software interchange; or, + + b) Accompany it with a written offer, valid for at least three + years, to give any third party, for a charge no more than your + cost of physically performing source distribution, a complete + machine-readable copy of the corresponding source code, to be + distributed under the terms of Sections 1 and 2 above on a medium + customarily used for software interchange; or, + + c) Accompany it with the information you received as to the offer + to distribute corresponding source code. (This alternative is + allowed only for noncommercial distribution and only if you + received the program in object code or executable form with such + an offer, in accord with Subsection b above.) + +The source code for a work means the preferred form of the work for +making modifications to it. For an executable work, complete source +code means all the source code for all modules it contains, plus any +associated interface definition files, plus the scripts used to +control compilation and installation of the executable. However, as a +special exception, the source code distributed need not include +anything that is normally distributed (in either source or binary +form) with the major components (compiler, kernel, and so on) of the +operating system on which the executable runs, unless that component +itself accompanies the executable. + +If distribution of executable or object code is made by offering +access to copy from a designated place, then offering equivalent +access to copy the source code from the same place counts as +distribution of the source code, even though third parties are not +compelled to copy the source along with the object code. + + 4. You may not copy, modify, sublicense, or distribute the Program +except as expressly provided under this License. Any attempt +otherwise to copy, modify, sublicense or distribute the Program is +void, and will automatically terminate your rights under this License. +However, parties who have received copies, or rights, from you under +this License will not have their licenses terminated so long as such +parties remain in full compliance. + + 5. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Program or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Program (or any work based on the +Program), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Program or works based on it. + + 6. Each time you redistribute the Program (or any work based on the +Program), the recipient automatically receives a license from the +original licensor to copy, distribute or modify the Program subject to +these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties to +this License. + + 7. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Program at all. For example, if a patent +license would not permit royalty-free redistribution of the Program by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Program. + +If any portion of this section is held invalid or unenforceable under +any particular circumstance, the balance of the section is intended to +apply and the section as a whole is intended to apply in other +circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system, which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 8. If the distribution and/or use of the Program is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Program under this License +may add an explicit geographical distribution limitation excluding +those countries, so that distribution is permitted only in or among +countries not thus excluded. In such case, this License incorporates +the limitation as if written in the body of this License. + + 9. The Free Software Foundation may publish revised and/or new versions +of the General Public License from time to time. Such new versions will +be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + +Each version is given a distinguishing version number. If the Program +specifies a version number of this License which applies to it and "any +later version", you have the option of following the terms and conditions +either of that version or of any later version published by the Free +Software Foundation. If the Program does not specify a version number of +this License, you may choose any version ever published by the Free Software +Foundation. + + 10. If you wish to incorporate parts of the Program into other free +programs whose distribution conditions are different, write to the author +to ask for permission. For software which is copyrighted by the Free +Software Foundation, write to the Free Software Foundation; we sometimes +make exceptions for this. Our decision will be guided by the two goals +of preserving the free status of all derivatives of our free software and +of promoting the sharing and reuse of software generally. + + NO WARRANTY + + 11.

The modules strive to be simple, well documented and +modification friendly, in order to help developers quickly learn their inner +workings. + +These examples are meant to teach you about code-level development for Drupal +8. Some solutions might be better served using a contributed module, so that +you don't end up having to re-invent the wheel in PHP. When in doubt, look for +an existing contrib project that already does what you want, and contribute to +that project. + + +How To Use The Examples +----------------------- + +There are three main ways to interact with the examples in this project: + +1. Enable the modules and use them within Drupal. Not all modules will have +obvious things to see within your Drupal installation. For instance, while the +Page and Form API examples will display forms, the Database API example does not +have much that is visible within Drupal. + +2. Read the code. Much effort has gone into making the example code readable, +not only in terms of the code itself, but also the extensive inline comments +and documentation blocks. + +3. Browse the code and documentation on the web. There are two main places to +do this: + +* https://api.drupal.org/api/examples is the main API site for all of Drupal. +It has all manner of cross-linked references between the example code and the +APIs being demonstrated. All of the Doxygen-based comments in the code are +parsed and made browseable here. + +* http://drupalcode.org/project/examples.git allows you to browse the git +repository for the Examples project. + +This project ships with a composer.json file. This is meant to illustrate how +to provide a composer.json file for a Drupal contrib project. You can read more +about how to use Composer with Drupal here: https://www.drupal.org/node/2718229 + +How To Install The Modules +-------------------------- + +1. The Examples project installs like any other Drupal module. There is extensive +documentation on how to do this here: +https://drupal.org/documentation/install/modules-themes/modules-8 But essentially: +Download the tarball and expand it into the modules/ directory in your Drupal 8 +installation. + +2. Within Drupal, enable any Example sub-module you wish to explore in Admin +menu > Extend. + +3. Rebuild access permissions if you are prompted to. + +4. Profit! The links for Examples material will appear in your Tools menu. This +menu appears on the left sidebar by default. You'll need to reenable it if you +removed it. + +Having seen the behavior of the various example modules, you can move on to +reading the code, experimenting with it, and hopefully grasp how things work. + +If you find a problem, incorrect comment, obsolete or improper code or such, +please search for an issue about it at http://drupal.org/project/issues/examples +If there isn't already an issue for it, please create a new one. + +Thanks. diff --git a/sites/all/modules/examples/examples/STANDARDS.md b/sites/all/modules/examples/examples/STANDARDS.md new file mode 100644 index 000000000..387656a33 --- /dev/null +++ b/sites/all/modules/examples/examples/STANDARDS.md @@ -0,0 +1,86 @@ +Developing with Coding Standards for Examples for Developers +============================================================ + +Examples uses mostly the same coding standards as Drupal core. + +If you see a discrepancy between the coding standards tools used by core and +those used by Examples, please file an issue so that Examples can follow core. + +Examples uses the `phpcs` tool to allow for checking PHP coding standards. We +use the `drupal/coder` project for Drupal-specific coding standards. + +We also use `eslint` for JavaScript coding standards, and `csslint` for CSS. + +Examples has a `phpcs.xml.dist` file at the root of the project. phpcs uses this +file to specify the current coding standards 'sniffs' which code in the project +must pass. + +Contributors should install `phpcs` in their local Drupal installation, and then +use that to run `phpcs` against Examples as part of their development and review +process. (See details below on how to install and run this tool.) + +Contributors can also patch the `phpcs.xml.dist` file itself, in order to fix +the codebase to pass a given rule or sniff. Patches which do this should be +limited to a single rule or sniff, in order make the patch easier to review. + +Examples also uses the Coder project (`drupal/coder`), which adds additional +Drupal-specific coding standards. We're currently locked to Coder version +8.2.8, but this should change to reflect the state of core's coding standards. + +Installing phpcs +---------------- + +Current versions of Drupal 8 core require phpcs and Coder as dev dependencies. +That means they're already probably installed in your core vendor/ directory. + +We need to tell `phpcs` to use the Drupal coding standard provided by Coder, +because it isn't configured that way by default. + +Like this: + + $ cd my/drupal/root/ + $ ./vendor/bin/phpcs --config-set installed_paths /full/path/to/drupal/vendor/drupal/coder/coder_sniffer/ + // phpcs now knows how to find the Drupal standard.

There is, however, this issue in core: +https://www.drupal.org/node/2499239 + +How To Run The Tests In The Drupal UI +------------------------------------- + +Generally, you should run tests from the command line. This is generally easier +than using Drupal's testing UI. However, here's how you can do it that way: + +Enable the Testing module. + +Visit the test list page at `admin/config/development/testing`. + +Since the tests are organized by module, you can search for a module name and +get all the tests for that module. For instance, type in 'node_type_example' for +all the tests related to that module. + +Click the check boxes next to the tests you want to run. If you find this +tedious, it's time to learn to use the command line. :-) + +Click 'Run Tests.' You're now running the tests. + +Step-by-step: How To Run The Tests. +----------------------------------- + +Begin with an installed Drupal codebase. Make a codebase, set up the database, +etc. Note that you can use an existing Drupal instance but the best practice is +to start fresh. Something not working right? Try a new installation. + +Use the dev branch of core for the latest release of Drupal. As of this writing, +it's 8.2.x.

If you are +doing development on Examples, you should have already checked out the git +repository into `modules/`, like this: + + $ git clone --branch 8.x-1.x https://git.drupal.org/project/examples.git modules/examples + +Now you can run `run-tests.sh`, which, despite having a `.sh` suffix is not a +shell script. It's a PHP script. + +You'll use the `--directory` option to have the test runner scan the Examples +module directory for tests. + +Also, importantly, if your test site has its own URL, you'll need to supply that +with the `--url` option. For instance, under MAMP, you must specify +`--url http://localhost:8888/`. + +You can also use `--concurrency` to speed up the test run, and `--browser` to +see detailed test results in a web browser instead of just text output in the +terminal. + + $ php ./core/scripts/run-tests.sh --browser --concurrency 10 --url http://localhost:8888/ --directory modules/examples + +This should run all the tests present in Examples. If you add a test and it +doesn't appear in the list of tests to run, then you'll need to double-check +that it's in the proper test namespace and that the class name (and thus the +file name) ends in Test. + +What Tests Should An Example Module Have? +------------------------------------------ + +Examples has a checklist for each module: +https://www.drupal.org/node/2209627 + +The reason we care about these tests is that we want the documentation +of these APIs to be correct. If Core changes APIs, we want our tests to +fail so that we know our documentation is incorrect. + +Our list of required tests includes: +* Functional tests which verifies a 200 result for each route/path defined by + the module. +* Functional tests of permission-based restrictions. +* Functional tests which submit forms and verify that they behave as + expected. +* Unit tests of unit-testable code. +* Other.

The Field Permission Example module shows how you can restrict view and edit permissions + within your field implementation. It adds a new field type called Fieldnote. Fieldnotes + appear as simple text boxes on the create/edit form, and as sticky notes when viewed. + By 'sticky note' we mean 'Post-It Note' but that's a trademarked term.

+ +

To see this field in action, add it to a content type or user profile. Go to the + permissions page ({{admin_link}}) and look at the 'Field Permission Example' section. This + allows you to change which roles can see and edit Fieldnote fields.

+ +

Creating different users with different capabilities will let you see these behaviors + in action. Fieldnote helpfully displays a message telling you which permissions it is + trying to resolve for the current field/user combination.

+ +

Definitely look through the code to see various implementation details.

The code in this module implements a couple of new features which you can see +in action.

+ +

Implements hook_help(): In hooks_example.module you'll find +an implementation of the hook hook_help() which is used to add contents to this +module's help overview. Visible at admin/help/hooks_example.

+ +

View counts: hooks_example_node_view() is an implementation +of the hook hook_ENTITY_TYPE_view() that adds a basic page view counter. You can +see this in action by navigating to any node on the site and looking for the the +text telling you how many times you've viewed that page.

+ +

Implements hook_form_alter(): In hookse_example.module +you'll find an implementation of hook_form_alter() which demonstrates the use of +one of the most commonly used alter hooks. You can view the altered form at +user/login.

+ +

+

In this example we create two content types for Drupal 8, using only YAML files. Well, mostly only YAML files... + One of our content types is locked, so the user can't delete it while the module is installed. For this we need + a very tiny amount of support code.

+

You can observe these content types on the content type admin page.

+

The simplest way to author the per-type YAML files is to create the content types within Drupal and then take the + YAML files from the configuration directory. Like this:

+
    +
  • Install Drupal 8.
    • +
  • Create a new content type at {{ add_types }}. Let's call it 'Nifty Content Type'.
    • +
  • Export the configuration from admin/config/development/configuration. Specific steps depending + on needs, and decisions made during Drupal 8 beta. You'll see a file called + node.type.nifty_content_type.yml.
    • +
  • Copy or move that file to your module's config/install directory, along with associated field + and form yml files.
    • +
  • Remove the uuid information from the configuration files.
    • +
+

You can see some of these YAML files in this module's config/install directory.

+

If you want to lock a content type created in this way, you'll have to implement hook_install() and + hook_uninstall(). In hook_install(), you'll set the content type to be locked. + In hook_uninstall() you'll set the content type to be unlocked.

+

Content types created in this way will remain available after the user has uninstalled the module. + If you were to fail to set the content type as unlocked, the user would not be able to delete it.

+

The Pager Example shows you how to create a paginated table. It uses + an Entity Query to retrieve nodes and the query checks that + the user has access to the nodes. You may test the access checking + feature by unpublishing some of your nodes and then viewing the + example as a user that is not allowed to see unpublished content.

In order to see this in action, make sure there are some nodes present in + your site. You can use the devel module to add some if needed, or just + create them.

The table on this page will show you two nodes per page.

PHPUnit for Drupal: A very basic how-to.

+ +

How to use this example module

+

You really should be reading the various docblocks in the test files.

+ +

How To:

+
    +

  • PHPUnit tests belong in their own directory, so they won't be loaded + by the autoloader during normal bootstrap. This means you should have a + /tests/src directory in the root of your module directory.

    +
    • + +

  • Your tests should be in the Drupal\Tests\[your_module]\Unit + namespace. Under Drupal's PSR-4 system, this means your PHPUnit-based + tests should go in a [your_module]/tests/src/Unit + directory.

    +
    • +

  • Your test case should subclass Drupal\Tests\UnitTestCase. +

    +
    • +
  • +

    You can run PHPUnit-based tests from within Drupal 8 by enabling the + Testing module and then selecting the PHPUnit group from the testing page. + As of this writing, this method doesn't provide any useful output. +

    +
    • +
+ +

Standard PHPUnit Practices

+

You can (and really, should) run PHPUnit from the command line.

+

On unix-based systems this means you need to cd core and then + 

./vendor/bin/phpunit
+

+

On Windows-based systems, assuming you have php in your path, + 

php ./vendor/phpunit/phpunit/composer/bin/phpunit --group phpunit_example
+

+

Also, you should mark your tests as belonging to a group, so they can be run + independently. You do this by annotating your test classes with + @group group_name. You should have a @group for + your module name, and you should also have a @group for + integrations, such as views. +

+

So, for instance, to run all of the PHPUnit example tests, you would type + 

./vendor/bin/phpunit --group phpunit_example
+

+

As you can see, including a @group annotation is a good idea.

    The Stream Wrapper Example module demonstrates a PHP stream wrapper implementation. + A stream wrapper is a class that implements something that looks and behaves like a + file system. A particular implementation of a stream wrapper is called a scheme. + Drupal 8 supports public, private, and temporary wrapper schemes. For example, you + access a file in your public uploads directory via a "public" file URI such as + public://images/big-logo.png. When you read, write, delete or move that + file, the public scheme's stream wrapper class + (\Drupal\Core\StreamWrapper\PublicStream) is invoked to do the reading, + writing, deletion or moving. PHP does this automatically for you, creating the wrapper + whenever some file operation needs to get done on a public:// file. +

    + +

    To demonstrate how to implement a stream wrapper, this example module creates a + session wrapper scheme. It uses your session data (created when you + log into Drupal) to create a nested array where the arrays represent directories, + and scalar values represent files. This is completely impractical, and frankly, + not terribly secure, so you should never enable this module on any site that's + open to the Internet. But without using any special libraries, our stream wrapper + class is able to create and delete directories, and read and write files. +

    + +

    If you want to play with session file URIs, we recommend also enabling + the File Example (file_example.module), which will let you do the same things with + the "session" scheme that you can do with public, private or temporary files.

    + +

    A longer description of what code is where can be found in + stream_wrapper_example.module. Definitely look through the code to see + various implementation details.

    Testing Frameworks in Drupal

    + +

    How to use this example module

    +

    You really should be reading the various docblocks in the files under + tests/src/.

    + +

    How To:

    +
      +
    • PHPUnit-based Drupal tests go in the tests/src directory, so + they will not be loaded by the autoloader during normal bootstrap. +
      • + +
    • Unit tests go in [your_module]/tests/src/Unit.
      • +
    • Kernel tests go in [your_module]/tests/src/Kernel.
      • +
    • Functional tests go in [your_module]/tests/src/Functional.
      • +
    + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +

    + +

    Standard PHPUnit Practices

    +

    You can run PHPUnit from the command line or via the run-tests.sh command.

    +

    You can specify which type of test you're running via + 

    phpunit --testsuite
    and + 
    run-tests.sh --types
    .
+
    There are many options to phpunit, but, for instance, to run all of the
+  testing_example phpunit tests, you could
+
    ./vendor/phpunit/phpunit/phpunit -c core/ ./modules/examples/testing_example
    
+

+#
+# Each tour file has two parts: 1) The tour properties, and 2) the tip

+#
+#
+# TOUR PROPERTIES
+#
+# The tour properties define information that applies to the tour as a whole.
+# Properties that you can define for your tours include the following:
+#
+#   id:         Each tour should have a unique ID. This id is used in the
+#               filename and appears as an ID in the HTML.
+#   module:     The machine name of the module containing your tour.
+#   label:      A human readable name for the tour.
+#   status:     A boolean, defining whether the tour is enabled.
+#   langcode:   A two-letter language code defining the language of your tour.
+#   routes:     An array of routes for which the tour is active. Specify these
+#               as an array with route_name and optional route_params (also an
+#               array). Route names are found in each module's routing.yml file.
+#
+#
+# TIP DEFINITIONS
+#
+# Here, you define each tip that you want to appear in your tour. Each of
+# the tips have properties that must be defined, including the following:
+#
+#   id:         Each tip needs a unique ID. This appears as an ID in the HTML.
+#   plugin:     The Tour API uses plugins for defining different types of
+#               tips. The 'text' plugin (for making text tooltips) is provided
+#               in core, but developers can define additional plugins for tips
+#               containing images, video, or other interactions.
+#   label:      The lable for the tip. This will be rendered in an h3 element.
+#   body:       The body of the tip. HTML markup is allowed.
+#   weight:     Tips within a tour are ordered by weight, beginning with the
+#               lowest number. Negative values are acceptable.
+#   location:   Defines the location of the tip, relative to its target.
+#               Acceptable values include: top, bottom, left, & right. If the
+#               location is not defined, the default value (bottom) will be
+#               used.
+#   attributes: Attributes provdied to the tip for various purposes. Use the
+#               following attributes to control the placement of the tip:
+#
+#                 data-id:      Places this tip on the DOM element containing
+#                               this ID.
+#                 data-class:   Places this tip on the DOM element containing
+#                               this class.
+#
+#               If you omit both the .data-id and .data-class, the tip will be
+#               shown as modal instead of being targeted to an element.

    About Tours
    
+
+
    The Tour module allows you you make instructional tours of user interfaces.
    
+
+
    The Tour module comes with Drupal 8 and makes it easy for developers to add
+    "Tours" for guiding users through unfamiliar user interfaces.
    
+

    Each tour is comprised of a series of tooltips that provide contextual
+    information about an interface. The user can start a tour by clicking the
+    "Tour" icon on the right side of the Drupal 8 toolbar. The tour icon is only
+    visible when there is a tour available on the current page.
    
+
+
    The Tour module provides the Tour API, which makes it easy for developers to
+    add tours to their modules. In most cases, adding a tour is as simple as
+    creating a YAML file in the config directory in their module, containing the
+    expected data. For a detailed example of such a file, see
+    config/install/tour.tour.tour-example.yml.
    
+
+
    If you are interested in building tours through a user interface, you may
+    want to look at the Tour UI module: https://drupal.org/project/tour_ui
    
+
+
    The Tour module uses the Joyride jQuery plugin for its underlying
+    functionality. You can find more information about Joyride at
+    https://github.com/zurb/joyride
