The script at Default/trim_trailing_white_space.py has method for on_pre_save event only. Here’s modified version that has a method that can be used with command too (key shortcut):

[code]import sublime, sublime_plugin

def trim_trailing_whitespace(view):
trailing_white_space = view.find_all("\t ]+$")
trailing_white_space.reverse()
edit = view.begin_edit()
for r in trailing_white_space:
view.erase(edit, r)
view.end_edit(edit)

class TrimTrailingWhiteSpaceCommand(sublime_plugin.TextCommand):
def run(self, edit):
trim_trailing_whitespace(self.view)

class TrimTrailingWhiteSpace(sublime_plugin.EventListener):
def on_pre_save(self, view):
if view.settings().get(“trim_trailing_white_space_on_save”) == True:
trim_trailing_whitespace(self.view)

class EnsureNewlineAtEof(sublime_plugin.EventListener):
def on_pre_save(self, view):
if view.settings().get(“ensure_newline_at_eof_on_save”) == True:
if view.size() > 0 and view.substr(view.size() - 1) != ‘\n’:
edit = view.begin_edit()
view.insert(edit, view.size(), “\n”)
view.end_edit(edit)[/code]

Would be nice to incorporate it into default package.
