accidentally changed line ending in git, now can't change back because it says nothing changed

Question

A few days ago, I accidentally changed the line endings of some file, and committed the change. (Was CRLF, is now LF by mistake.) I still don't know if this was my editor being too clever, or perhaps git being too clever. (Actually I suspect it's git, based on my experiences trying to undo this.) Either way, it's done and I'd like to fix it. I thought I could just change the line endings in my editor, then do a commit with just the line ending change. Git refused, claiming I didn't change anything. So I added a dummy change as well, but it then committed the dummy change but also transformed the line endings, so they are still LF. Possibly relevant git settings:

C:\Users\ZKZ4PL2\eqs\hot-connect>git config core.eol

C:\Users\ZKZ4PL2\eqs\hot-connect>git config core.autocrlf
input

Any ideas?

Answer 1

First, set core.atocrlf to false, in order to avoid any automagic eol transformation by Git.

 git config --global core.autocrlf false

Second, check any .gitattributes files, for core.eol directives in it.

If you have none, then changing EOL in your editor should be picked up on git add.
