For MAC users:
Preferences > Editor > General > Ensure line feed at file end on save
File > Settings... > Editor > General > Ensure line feed at file end on Save
Help > Find Action... (Ctrl+Shift+A) > type "Ensure line feed" > switch the toggle to ON (using the mouse click or Enter) for "Other: Ensure line feed at file end on Save" line
Possible alternative with a number of handy features is EditorConfig
Just submit an .editorconfig
file to your repo
[*]
insert_final_newline = true
And it will work natively not only in Idea, but in all major IDEs (some require a plugin).
Now all team members would have same configuration, eol, eof, and no more tabs vs spaces :)
As Rider (IDEA's cousin for .NET) is driving me crazy, this might be helpful for those writing C# as Ensure line feed at file end on Save
alone won't work. It needs
File → Settings → Editor → Code Style → C# → Line Breaks and Wrapping → Line feed at end of file
.
I don't remember changing it and I haven't imported any settings for sure, so I guess it's by default disabled.
