Coder does not recognize class or method names in @see blocks.

Patch/fix:

A related bug is that it demands parentheses after class names, which I'm told is incorrect.

Indeed. Here's a patch that confirms the bug.

Also see #1198452: @see references should each be on their own line.

oh, no testbot for Coder? Odd.

The intention of #3 obviously was to prove that expectations are failing (after adding them). But without testbot, that's kinda pointless ;)

So here's the merged and minimally fixed patch, but the change to the regex doesn't look correct to me. (EDIT: ...and fails tests)

The regex looks good. Patch still applies.

Not sure whether this should be included in this patch version, but is also erroneously flags functions in namespaces. For instance this triggers the warning:

namespace Foo {
  function bar() { 
  }
}

/**
 * Implements hook_somehook().
 *
 * @see Foo\bar()
 */
function foo_somehook() {
}

Since namespaces are fast becoming more common since D8 started and their inclusion in the coding standards (http://drupal.org/node/1353118), the patch should probably address them too.

Marked #1455950: @see MyClass::myMethod() is not allowed as a duplicate of this issue.

This patch doesn't apply anymore. Even after a reroll a lot of the tests fail.

Coder 7.x-1.x is frozen now and will not receive any updates. Coder 8.x-2.x can be used to check code for any Drupal version, Coder 8.x-2.x also supports the phpcbf command to automatically fix conding standard errors. Please check if this issue is still relevant and reopen against that version if necessary.
