How to autoload committed files if custom xml is presented?

[MDaskalovAtBE]

How to make my own xml file that when picked it will resolve the committed files auto and there will be no need of
<file>/path/to/file/</file>
foreach file that has been changed?

In my .xml I have

<?xml version="1.0"?>
<ruleset xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" name="PHP_CodeSniffer" xsi:noNamespaceSchemaLocation="vendor/squizlabs/php_codesniffer/phpcs.xsd">
    <description>The coding standard for PHP_CodeSniffer itself.</description>

    <arg name="basepath" value="."/>
    <arg name="colors"/>

    </rule>

    <!-- Have 12 chars padding maximum and always show as errors -->
    <rule ref="Generic.Formatting.MultipleStatementAlignment">
        <properties>
            <property name="maxPadding" value="12"/>
            <property name="error" value="true"/>
        </properties>
    </rule>


    <!-- Private methods MUST not be prefixed with an underscore -->
    <rule ref="PSR2.Methods.MethodDeclaration.Underscore">
        <type>error</type>
    </rule>

    <!-- Private properties MUST not be prefixed with an underscore -->
    <rule ref="PSR2.Classes.PropertyDeclaration.Underscore">
        <type>error</type>
    </rule>

    <!-- The testing bootstrap file uses string concats to stop IDEs seeing the class aliases -->
    <rule ref="Generic.Strings.UnnecessaryStringConcat"/>

</ruleset>

When I committed this file

<?php

$something = array(
    'asd' => 'asd',
    'asdss'   => 'sss'
);

echo $something;

I was expecting it will fail, but it returned green, if I use the default PSR2 as arg in the .yml and remove the xml the file fails as it should.

Thanks.
