Drupal 8.x

Hello everyone.

I've installed Drupal 8 and got a notice on the status page about installing the Twig C extension. I followed the link;

http://twig.sensiolabs.org/doc/installation.html

...however, there's only this relevant path in the Drupal 8 installation directory:

./vendor/twig/twig

which has these contents:

CHANGELOG composer.json lib LICENSE phpunit.xml.dist README.rst

Hello Drupal Community,

Forgive me if this is posted in the wrong forum. If so, please tell me the correct forum and I'll repost it there. Also, I've searched and searched and either my search-fu is no match or the results I do find are rather dated.

I've been assigned a project whereby I'll be creating multiple sites using the following configuration:

www.example.com
111.example.com
222.example.com
333.example.com

Hello, I want to make a dashboard item and display it on a Drupal 8 page. I have an REST API for legacy systems that produces JSON. How do I consume that REST API data and display it in a block on a page? Is that for a block? View? New module, something else?

I would have several of these items from various systems on the page, so multiple "dashboard" items would be there to choose from based upon who is logged in.

Hello,

I have just installed a local copy of Drupal 8 and I would like to install a CKEditor plugin to be used in my Drupal installation. I am assuming that I will first need to convert the plugin so that Drupal will recognize it and install the files to the correct locations. Is there any sort of automated process for this or will I have to do it manually? If it's a manual process, can anyone direct me to a tutorial that explains how to convert a CKEditor plugin to be compatible with Drupal 8?

I have a custom block with its twig template suggestion.

I want to add an html head link tag when this block is loaded.
ex: <link rel="import" href="test.html">

In the twig template I can use attach_library to add css/js to , but I don't know how to add html imports in twig.

Is it possible to achieve this using mytheme_preprocess_block function, or any other hook?

Hello! I cannot understand how to add conditions to drupal 8 default webfrom. I need to show additional field in my form when user select specific value in another field. And I need configure message which will be sent to user (I need to include some fields).
P.S. I very bad know drupal, may be I need to add some modules?! Now, I have stock drupal system without third modules.
