24.3; ruby-mode sets require-final-newline unconditionally |
|

I am the maintainer of a package called emacs-wspace, available at
github at https://github.com/glasserc/ethan-wspace/. The goal of the
package is to help keep whitespace in files clean without introducing
spurious whitespace changes. In order to do this, the package requires
users to turn off require-final-newline and sometimes
mode-require-final-newline. If ethan-wspace discovers that
require-final-newline is set to t, it admonishes the user.
One user reported that ruby-mode triggers this warning. Sure enough, in
ruby-mode.el at line 287, I see:
(set (make-local-variable 'require-final-newline) t)
There is some precedent for doing this sort of thing with the variable
mode-require-final-newline. Is it possible for ruby-mode to respect this
variable?
More discussion can be found at this bug report for cucumber.el, another
mode which seems to borrow the pattern from ruby-mode:
https://github.com/michaelklishin/cucumber.el/pull/51
Thank you for your time.

Removed in the `emacs-24' branch. It was a remnant from before ruby-mode
was made to inherit from prog-mode.
