Target the class name of a fully-qualified class in a "use" statement

[dstrunk]

I'm attempting to target the class name in a fully qualified class in a use statement for use in a colorscheme (https://github.com/tomasiser/vim-code-dark, for those interested). One key part of the colorscheme is the highlighting of the classname within a namespaced "use" statement, e.g.:

In the above, the targets are App, User, Entry, and Model.

I think I've got the regex required to target this bit of the use statement, but can't figure out how to implement: /\(function\_s)+\)\@!\(\(\\\)\@<=\)\(\h\w*\)\(\(;\|\_s\)\@=\)/

could somebody point me in the right direction for implementing this? I've tried the following underneath the " use statement comment, as well as added phpUseFinalClass to the nextgroup under phpUseClass:

syn match phpUseFinalClass /\(function\_s)+\)\@!\(\(\\\)\@<=\)\(\h\w*\)\(\(;\|\_s\)\@=\)/ contained contains=phpUseNamespaceSeparator

FWIW, I'm aware this regex isn't exhaustive for {} use statements, just trying to get a proof of concept done for a potential PR.

I'm somewhat confused. You seem to be referencing multiple things. Can you give a code example and surround the bit you want to highlight differently in <<< and >>>, e.g.,:

<?php

namespace App;

<<<final>>> class MyClass
{
}

[dstrunk]

sure (I admit the name phpUseFinalClass needs some tweaking):

<?php

namespace <<<App>>>;

use App\<<<User>>>;
use Illuminate\Database\Eloquent\<<<Model>>>;
use Some\Other\<<<Class>>> as Alias;
use Some\<<<Class>>>, Another\Random\<<<Class>>>;
use One\More\{
    <<<TestClass>>>,
    <<<ForGoodMeasure>>>
};

Edit:

Here's a preliminary PR that will hopefully give a better explanation of what I'm shooting for: https://github.com/dstrunk/php.vim/commit/a4d1ab67d333a966f5e6d97e1dd6a7d589dd52f6

Okay, second try, GitHub just lost my original, long, comment. Try this:

syn keyword phpInclude namespace contained nextgroup=phpNamespaceName skipwhite skipempty
syn match phpNamespaceName /\(\\\|\h\w*\)*\h\w*/ contained contains=phpUseNamespaceSeparator skipwhite skipempty
syn match phpNamespaceOrUseClassName /\h\w*\(\_s*;\)\@=/ contained containedin=phpUseClass,phpNamespaceName,phpUseAlias

hi phpUseClassName guifg=#00c400

should get you this:

Awesome, thanks so much! Looks like I was overthinking regex per usual. This should get me pointed in the right direction for some of the other use-cases.

Would you be interested in a PR for this? You can close if not

This is the kind of thing that can live in the Snippets section of the README. Let me know if you run into any edge cases.
