Why are my line-endings still wrong according to CodeSniffer?

问题

I made a git hook that checks my code style before commit. It passes the staged files to CodeSniffer. I use the PSR-2 code style which means newlines should be \n even on Windows. However even after changing PhpStorm settings and git settings it still gives me the error that the newlines are \r\n. Why does this happen?

PhpStorm
Searching for \r\n with regex on does not return instances, so I believe the problem to lie with git.

.gitconfig

[core]
    autocrlf = false
    editor = \"C:/Program Files (x86)/GitExtensions/GitExtensions.exe\" fileeditor
    eol = lf
[user]
    name = Thomas Moors
    email = thomas.moors@*****.nl
[merge]
    tool = kdiff3
[mergetool "kdiff3"]
    path = C:/Program Files (x86)/KDiff3/kdiff3.exe
[diff]
    guitool = kdiff3
[difftool "kdiff3"]
    path = C:/Program Files (x86)/KDiff3/kdiff3.exe

The error

Fix the error before commit please

edit: using another editor (n++) the problem does seem to lie with phpstorm. Replacing \r\n fixes the problem. So why does PHPStorm not work properly?

Not necessarily with git.

IDE (PhpStorm) stores all lines in memory with normalized line separator (which is \n / LF) and when you saving the file it replaces them with actual line separator symbol detected on file opening. This also means that if you happen to have mixed line endings in one file (e.g. both CRLF and LF) .. after save it will use only one style (e.g. only LF).

Normalized line ending allows you to execute your regex searches/replaces in a bit more simpler way -- no need to worry about what the actual symbol is.

Now -- the Code Style settings page -- as you can see in that hint below the field, it says: "Applied to new files". This means that this setting does NOT affect existing files in any way.

To change line ending for a particular existing file: open the file and either change it via appropriate section in Status Bar .. or via File | Line Separators

So why does PhpStorm not work properly?

It works properly -- you just happen to not know how to change the line separator style.
