Is there a way to specify end-of-line characters?

Hi, I’m using Windows when my team has others using Mac. Our .editorconfig specifies that we use \n as EOL character, I’ve also set my .gitconfig autocrlf=input. So when we write test fixtures for codemods, there are \ns in the files. But when running tests, the output will have \r\ns, causing tests fail on my machine.

I’m wondering if there is a way to specify EOL characters when running jscodeshift?

To add to that, you can supply the following option to the CLI command to fix this broken default behavior:

--printOptions='{"lineTerminator":"\n"}'

Side rant: It’s really nice that you have to search through a myriad of issues and dependencies to determine that some developers arbitrarily decided that it was a good idea to use the OS line endings rather than honor the contents of the original file or default to the sane LF character. It’s further great that there is no mention of this in the README of this repo or the react-codemod repo to warn users of this arbitrary design decision that will likely break tests as @tw0517tw mentions.

@ksummerlin Your command looks correct. Unfortunately, this works on some of the scripts, but not all. I have a PR open that consistently consumes the printOptions on all scripts, but it has not been reviewed yet by the collaborators:

You can clone my existing fork and run that command again and it should work (assuming transformation still need to be made in your React files). Alternatively, you can also run the dos2unix command if you are using MinGW or some other Bash shell:
