问题
I changed a RubyMine settings few days back. It was related to changing the end of line character from '\r\n' to something else, so that it is only Mac compatible.
Now, each file I edit is changed completely in git diff. Also, I can't recall which setting option was it.
Any guesses?
回答1:
File | Line Separator (or the same in status bar, next to file encoding) which will allow to see and change line ending for current file.
For newly created files check Settings (Preferences on Mac) | Code Style | General -> Line separator (for new files)
