VSCODE snippet PHP to fill namespace automatically

I'm trying to create a VSCODE CODE SNIPPET for PHP that automatically put the namespace (based on folder path).

The idea is make a substitution on the directory of the current document, considering that all my class are located inside the MVC folder, and that this is located inside the src folder, examples:

/dev/project/src/MVC/Models/Access/Auth, or
/home/user/dev/project/src/MVC/Models/Access/Auth, or
/any_other_folder/src/MVC/Models/Access/Auth

I got the full folder name with VSCODE snippet variabe $TM_DIRECTORY.

Aparently hasn't error on REGEX, as you can see on: https://regex101.com/r/P8CpkX/1

My try of the snipped code:

"namep": {
        "prefix": [
            "namep"
        ],
        "body": [
            "",
            "// TM_DIRECTORY: $TM_DIRECTORY",

            "namespace ${TM_DIRECTORY/.*src\/(([^\/]*)(\/)?)|(\/)([^\/]*)/$2\\$5/g};"
        ],
        "scope": "php",
        "description": "Try to put namespace automatically"
    }

It results in:

// TM_DIRECTORY: /home/user/dev/project/src/MVC/Models/Access/Auth
namespace ${TM_DIRECTORY/.*src/(([^/]*)(/)?)|(/)([^/]*)/$5/g};

But the expected is (as demonstrated on REGEX):

// TM_DIRECTORY: /home/user/dev/project/src/MVC/Models/Access/Auth
namespace \MVC\Models\Access\Auth;

Could anyone helps to fix it?

Thanks a lot!!!

Solution

You can use

"namep": {
    "prefix": [
        "namep"
    ],
    "body": [
        "namespace \\\\${TM_DIRECTORY/(?:.*[\\/\\\\])?src[\\/\\\\]([^\\/\\\\]*)[\\/\\\\]?|[\\/\\\\]([^\\/\\\\]*)/$1\\$2/g}",
    ],
    "scope": "php",
    "description": "Try to put namespace automatically"
}

See the regex demo.

It matches

(?:.*[\/\\])? - an optional occurrence of any 0+ chars other than line break chars as many as possible and then either \ or /
src[\/\\] - an src string and then //\
([^\/\\]*) - Group 1: any zero or more chars other than / and \
[\/\\]?- an optional //\ char
| - or
[\/\\] - a \ or / char
([^\/\\]*) - Group 2: any zero or more chars other than / and \
