Converting to Drupal

Hi Guys, 

This cache_clear_all function is no more in D8 whats the actual replacement for this ? 

I want the actual replacement, In D7 I'm using this function as :

cache_clear_all($cid, 'cache_API_NAME_api', TRUE);

to clear the cache from the api. 

I want the function which will work similar to this. 

Note: I had tried drupal_flush_all_caches() as a replacement of this but it is only clearing the Drupal cache not from the api. 

Hello i have interest to know about installation profile and i looking information about this.

This is all what i find and i would like to know more:

In MediaWiki one can link from one internal webpage to another internal webpage by wrapping the text with four brackets.

[[TEXT]]

The output will be a link to a webpage with the same alias as TEXT, in that website.

In Drupal however, there is no such linking mechanism, let along, aliases would sometimes be different than the H1.

Hi Guys, 

I want a variable in menu.html.twig file but it is not working for me. 

I have tried this: 

This function I have written in my theme's .theme file 

/**
 * @param $variables
 */
function my_theme_name_preprocess_menu(&$variables)
{
    $account = \Drupal::currentUser();
    $variables['current_username'] = $account->getDisplayName();
}

And I am calling this variable in menu.html.twig file like this: 

In MediaWiki, I store a few chunks of text in simple templates (templates that don't even have a parameter).

In each relevant article, I call any such text chunk this way:

{{TEMPLATE_NAME}}

How to achieve similar functionality in Drupal?

I thought about creating a block and somehow call it in any relevant node but how to call a block from a node (preferably without creating a view)?

I wish to manually migrate all articles from MediaWiki to Drupal.

In MediaWiki I use Parameterized uniform text for most articles and I need similar functionality in Drupal.

To explain the concept of uniformed parameterized text, in MediaWiki I did the following:

1) Creating Template:A with the following parameter

The term {{{1}}} is used to describe

2) Calling Template:A in an article edit mode
