@muuvmuuv Thanks for creating this failing test case! I'm not familiar enough with PHP-CodeSniffer to recognize the problem here. This is the applicable code: https://github.com/Unibeautify/beautifier-php-codesniffer/blob/master/src/index.ts#L91-L100
Once we know how PHP-CodeSniffer expects to receive the arguments we can easily change it.

@Glavin001 me neither. I will create an issue on their repo. I have also recognised that phpcbf has problems with files without an extension or another than .php, maybe that is another issue of phpcs

@Glavin001 okay it seems it is like it is, we could only add a filter to allow files without extension but I think this is out of scope somehow. Let's just leave it as it is and if someone will report this again, we will point to squizlabs/PHP_CodeSniffer#1754 and squizlabs/PHP_CodeSniffer#2225
