Atom text editor remove trailing whitespace on save

Question

I use Sublime text. Now I am trying Atom. When I save any file in sublime text it does not include any trailing blank line. But saving any file in Atom leaves a trailing blank line. How do I force Atom not to leave trailing white spaces?

Solution 1

Under your Atom Preferences go to Packages tab and search for whitespace. Click on the whitespace package and uncheck Ensure Single Trailing Newline option

Solution 2

On global level this can be changed using settings in Whitespace package, but if you want to disable it for a specific language you have to use syntax-scoped properties in your config.cson.

'.text.html.php': # php overrides
  whitespace:
    ensureSingleTrailingNewline: false
    removeTrailingWhitespace: false

'.source.ruby': # ruby overrides
  whitespace:
    ensureSingleTrailingNewline: false
    removeTrailingWhitespace: false

To see the scope of language go to Packages tab and search for your language.

Click on the settings of the language package and you can see the scope:

Solution 3

Go to packages and find "whitespace", go to it's settings and uncheck the last checkbox.

I think its even better if we unckeck "Ignore whitespace On current line". This will remove the trailing whitespace of current line at the time when file is saved.

Could this message get any more cryptic? Lol - I'm just over-joyed to have Atom mangle a long file's diff because another dev left some trailing spaces only to find that it is not possible to find this setting by name. Few.. Anyone notice that the name changed from Package to Settings?

Maybe this is a new setting, but there is a Remove Trailing Whitespace checkbox at the bottom of the settings section. Unchecking it preserves all trailing whitespaces.

Your answer is even more detailed than the official docs at github.com/atom/whitespace, thanks for taking the time to put this up! :-) I would love to configure atom this way, but I can't get it to work, atom keeps turning two trailing newlines into a single one in my jinja2 files. Scope is .text.html.jinja, config matches yours, but doesn't work. Global it is then :-(

The image showing how to find the scope was particularly useful. I've since also found the scopes listed in the grammar selector (by default to the right of the line endings, line number and encoding at the bottom of the window, or with the default shortcut ctrl+shift+L).

Do you have any idea how hard it is to read your screenshot? Us a dark theme in your own work if you must, but a light theme makes a much more readable image.
