Visual Studio Snippet: Can I use TM_FILENAME to get a namespace from RELATIVE

I am toying with Visual Studio Snippets for a while now, and wonder if/how I can use TM_FILENAME to get a namespace from RELATIVE_FILEPATH. For example, I have:

RELATIVE_FILEPATH = src\model\RegisterModel.php

TM_FILENAME = RegisterModel.php

I want to strip the latter from the first, and the last \ as well, so I will end up with src\model

I can get it working if I use RegisterModel.php as a string, but not if I use TM_FILENAME as a variable. Is that even possible?

This is what works: ${RELATIVE_FILEPATH/(RegisterModel.php)//gi}

But I want something like this: ${RELATIVE_FILEPATH/(TM_FILENAME )//gi}

Thanks in advance!

This will get you what you want:

"filepath": {
  "prefix": "rfp",
  "body": [
    "${RELATIVE_FILEPATH/(\\\\[^\\\\]*)$//i}",  // with lots of escapes
  ],
  "description": "directories of current file"
}

${RELATIVE_FILEPATH/${TM_FILENAME}//gi} will not work as according to the grammar only a regex can go into that ${TM_FILENAME} spot in the transform. See snippet grammar.

Relevant part of the grammar: transform ::= '/' regex '/' (format | text) '/' options

${RELATIVE_FILEPATH/[${TM_FILENAME}]//gi} results in:

src\od\Rgsrod.php because [${TM_FILENAME}] is treated as a regex (just a alternate list of those characters literally) and so each of those characters is removed from the RELATIVE_FILEPATH.

This is what I was trying to create. This snippet creates a php class template with the proper class name and namespace from the file name and location.

So, snippet

  "php class": {
    "prefix": "_pclass",
    "body": "<?php\n\nnamespace app\\\\${RELATIVE_FILEPATH/(\\\\[^\\\\]*)$//i};\n\nclass $TM_FILENAME_BASE{\n\n\tpublic function __construct(){}\n\n\tpublic function $1($2){\n\n\t\t$3\n\t}\n}",
    "description": "PHP class"
  }

called in I:\xampp\htdocs\mvc2\src\core\form\Field.php creates

<?php

namespace app\src\core\form;

class Field{

    public function __construct(){}

    public function (){

        
    }
}

with the cursor on the method name. Saves me quite a bit of time, hope it's just as helpful for others.
