[jira] [Commented] (NETBEANS-377) Only underline the non-matching part of namespace

["Tomáš Procházka (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/NETBEANS-377?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17257169#comment-17257169 ] 

Tomáš Procházka commented on NETBEANS-377:
------------------------------------------

[PSR-4|https://www.php-fig.org/psr/psr-4/] standard is evolution of [PSR-0|https://www.php-fig.org/psr/psr-0/] where workarounds for absence of namespaces in PHP before 5.3 were removed.
 Most notable changes are:
 * Underscore character is no longer namespace separator in class name in PSR-4.
 * Namespace prefix can be mapped to base directory.
 * Directory of file must match namespace after prefix.

So I think best solution is to prepare separate PSR-4 validations. Current PSR-0 validations are good starting point. Future enhancements can add mapping from namespace prefix to base directory (manually defined or even read from composer.json).

> When the namespace does not correspondent to the directory structure, the namespace is underlined. Fine!
> But with PSR4 structure, the start of the namespace is often different to the directory structure. But the end should match.
> I suppose to only underline the part of the namespace, which does not match the directory structure. Then the user can determine himself if this part is because of PSR-4 or because of a typo.
