validate/generate command fails when spec file is created with CRLF on windows

[ishantanu]

Hello,

I was testing adding new plugins to sloth and I saw that sloth validate command fails when the Sloth spec is created with CRLF.

The error message doesn't mention any of this. However, when I copied an existing spec and edited the plugin id, it worked. Similarly, when I created a test.yml file with LF, the validate as well as generate command worked.

Example:

File created using default CRLF:

$ sloth validate -p plugins/ -i test/integration/ --debug

I confirm having the same issue when building on Windows with a Docker container running Sloth. Converting the .yml file to LF instead of the default CRLF fixed the error but it was definitely not obvious to find the right fix.
