With this module links can +be added easily to any content types and profiles and include advanced +validating and different ways of storing internal or external links and URLs. It +also supports additional link text title, site wide tokens for titles and title +attributes, target attributes, css class attribution, static repeating values, +input conversion, and many more. + + + +REQUIREMENTS +------------ + +Project in Drupal 7 requires the following modules: + + * Fields API (Fields API is provided already by core) + * Panels (https://drupal.org/project/panels) + +Drupal 8: + + * Link is in core now. No installation needed. Yay! Don't forget to activate + it. It's deactivated by default. + + +INSTALLATION +------------ + +Install as you would normally install a contributed Drupal module. See: +https://drupal.org/documentation/install/modules-themes/modules-7 for further +information. + + +CONFIGURATION +------------- + + * Configuration is only slightly more complicated than a text field. Link text + titles for URLs can be made required, set as instead of URL, optional + (default), or left out entirely. If no link text title is provided, the + trimmed version of the complete URL will be displayed. The target attribute + should be set to "_blank", "top", or left out completely (checkboxes provide + info). The rel=nofollow attribute prevents the link from being followed by + certain search engines. More info at Wikipedia + (http://en.wikipedia.org/wiki/Spam_in_blogs#rel.3D.22nofollow.22). + + +EXAMPLE +------- +If you were to create a field named 'My New Link', the default display of the +link would be: +
+[Title]
 where items between [] characters would be customized +based on the user input. + +The link project supports both, internal and external URLs. URLs are validated +on input. Here are some examples of data input and the default view of a link: +http://drupal.org results in http://drupal.org, but drupal.org results in +http://drupal.org, while will convert into http://drupal.org and +node/74971 into http://drupal.org/project/link + +Anchors and query strings may also be used in any of these cases, including: +node/74971/edit?destination=node/74972#pager + + +THEMING AND OUTPUT +------------------ +Since link module is mainly a data storage field in a modular framework, the +theming and output is up to the site builder and other additional modules. There +are many modules in the Drupal repository, which control the output of fields +perfectly and can handle rules, user actions, markup dependencies, and can vary +the output under many different conditions, with much more efficience and +flexibility for different scenarios.

+
+$ scripts/run-tests.sh --color --url http://example.com/ --php `which php` --concurrency 4 --verbose --directory 'sites/all/modules/contrib/views/tests' 2> /dev/null
+
+Explanation:
+  --color
+    Colorizes the output. Optional.
+  --url http://example.com/
+    The name of the Drupal 7 hostname used locally for running tests, e.g.
+    "http://drupal7.dev". Required.
+  --php `which php`
+    Tells the test runner the path to the PHP binary. Only necessary if the test
+    runner is unable to find the path automatically or to use an alternative
+    PHP binary. Optional.
+  --cuncurrency 4
+    Run multiple test processes simultaneously. Four appears to be a good
+    balance between melting the computer and improving performance. Optional.
+  --verbose
+    Display results for all of the assertion statements after the summary
+    details. Optional.
+  --directory 'sites/all/modules/contrib/views/tests'
+    Run all of the commands in the following directory. The path is relative to
+    the Drupal installation's root directory. This will run all of Views' tests
+    in one go, rather than either repeating the names of test groups or running
+    multiple commands. Optional.
+  2> /dev/null
+    Outputs all error messages to /dev/null, i.e. hides them. Optional.
