For example "fgrep -n -i foo" searches standard input for foo with -n and -i options, while "fgrep -n -- -i foo" searches for -i in foo with -n option. What this means for rake is that "rake -- --tasks" should treat "--tasks" as a target/task instead of an option. It doesn't appear to do that ("rake -- --tasks" appears to execute the default task), which may be an issue. Considering rake is "ruby make", there is an argument to be made that it should operate like make: $ make -n foo make: don't know how to make foo $ make -- -n foo make: don't know how to make -n Note that the standard unix "--" behavior is for options handling only, and is unrelated to your example "rake some_task -- some_arg", which doesn't contain options. > Now if rake was independent from Ruby distribution we should be done and I wouldn't arguee about this decision here. > > But it is part of stdlib, and as so, I think this should be a Ruby core developers decision. > > I don't think it is reasonable to break expecations of how programs should work. I respect Jim's opinion and I'm grateful for all his work, but I just think we should discuss this decision further more. After all rake is bundled with Ruby, it is not just an isolated gem. I agree with Eric that it should be Jim's decision, unless matz wants to fork rake. ---------------------------------------- Bug #6548: Rake doesn't ignore arguments after -- https://bugs.ruby-lang.org/issues/6548#change-31023 Author: rosenfeld (Rodrigo Rosenfeld Rosas) Status: Closed Priority: Normal Assignee: drbrain (Eric Hodel) Category: lib Target version: 2.0.0 ruby -v: ruby 1.9.3p125 (2012-02-16 revision 34643) [x86_64-linux] I've created this issue first in GitHub before I realized that Rake is now part of stdlib: https://github.com/jimweirich/rake/issues/115 I'll copy it here: rake some_task -- some_arg Raises an error after running some_task: Don't know how to build task some_arg. -- http://bugs.ruby-lang.org/
