github and line separators

https://git-scm.com/book/en/v2/Customizing-Git-Git-Configuration#_formatting_and_whitespace " You can tell Git to convert CRLF to LF on commit but not the other way around by setting core.autocrlf to input:

$ git config --global core.autocrlf input "

Per-repository settings

Optionally, you can configure a .gitattributes file to manage how Git reads line endings in a specific repository. When you commit this file to a repository, it overrides the core.autocrlf setting for all repository contributors. This ensures consistent behavior for all users, regardless of their Git settings and environment.


in Intellij there is an "Inconsistent line separators inspection", to check if the files have "line terminator" different from the default setup for the project
"This inspection detects files with line separators different from the project default. E.g. you set the line separator to "\n" in the Settings|Code Style|Line separator, and the file you are editing uses '\r\n' as a line separator"
