Sublime Text片段，用于插入PSR-0名称空间 [英] Sublime Text snippet to insert PSR-0 namespace

问题描述

我正在尝试制作一个Sublime文本片段，该片段在以下行中插入一个PHP样板类:

I'm trying to make a Sublime Text-snippet that inserts a PHP boilerplate class, in the lines of:

<?php

namespace Namespace\Subnamespace;

class TestClass
{
    public function __construct()
    {
        //code...
    }
}

使用 PHP-FIG 标准(或类似标准)时，名称空间和类名都可以是从文件的路径获得.上面示例中的文件将放置在/Users/Projects/Whatever/src/Namespace/Subnamespace/TestClass.php中.

When using PHP-FIG standards(or similar), both the namespace and classname can be obtained from the path of the file. The file in the example above would be placed in /Users/Projects/Whatever/src/Namespace/Subnamespace/TestClass.php.

这是我到目前为止所拥有的:

This is what I have so far:

<snippet>
    <content><![CDATA[
<?php
namespace ${1:Namespace};

class ${TM_FILENAME/(.*)[.](.*)/$1/g}
{
    public function __construct()
    {
        ${0://code...}
    }
}
]]></content>
    <tabTrigger>phpclass</tabTrigger>
    <scope>text.html</scope>
</snippet>

我已经想出了如何获取类名-但是事实证明，获取名称空间要困难得多.我离正则表达式专家还很远-这需要:

I've already figured out how to get the classname - but getting the namespace has proven to be much more difficult. I'm far from an expert in regexes - and this one requires:

1. 在src/
之后获取所有内容
2. ...并且在最后一个/
之前
3. 将所有剩余的斜杠翻转为反斜杠.

1. Getting everything after src/
2. ...and before the last /
3. Flipping all the remaining slashes to backslashes.

/Users/Projects/Whatever/src/Namespace/Subnamespace/TestClass.php变为Namespace\Subnamespace.

这是我在该主题上发现的最相关的主题，但这是远远超过了我的头，甚至无法正常工作.

This is the most relevant thread I've found on the subject, but it is way over my head, and I couldn't even get it working.

有人可以帮我吗?

推荐答案

此处是名称空间替换，可在ST-3中的两个以上级别上使用:

Here is a namespace substitution that works at more than 2 levels in ST-3:

namespace ${1:${TM_FILEPATH/(?:.*src\/)|(\/)?([^\/]+)(?=\/)|(?:\/[^\/]+\.php$)/(?1:\\$^N:$^N)/g}};

文件:/path/to/project/src/sub1/sub2/sub3/sub4/class.php

输出:namespace sub1\sub2\sub3\sub4;
