I have Ruby code that uses "keyword arguments" like so:

def run_cmd(command, arg1: true, arg2: nil)
  ...
end

When I run the code, it works as expected, but my IDE doesn't seem to know how to interpret this. It renders the formatting of my entire file incorrectly because of these keyword arguments. Are keyword arguments not supported by Eclipse's Dynamic Languages Toolkit? (I'm using DLTK version 2.0.0) If not, is there a different Eclipse plug-in I should be using for Ruby?

You don't even need to know anything about Ruby or DLTK to answer this question, just common sense is enough:

Keyword arguments were added in Ruby 2.0, which was released in honor of Ruby's 20th anniversary on February, 24th 2013. Eclipse DLTK 2.0.0 was released on June, 24th 2010, over ten years ago and almost three years before Ruby 2.0.

So, by the simple laws of phyics and some common sense, it is immediately clear that DLTK 2.0.0 cannot possibly support Ruby 2.0 keyword arguments, because they simply did not exist back then.

As a general rule, you should expect some breakage and limitations when using ten year old IDEs.

  • I see... I just recently installed DLTK using the update site `http://download.eclipse.org/technology/dltk/updates` and it installed version 2.0, but I guess that update site must be out of date since that's such an old version of DLTK, as you say. I guess I'll have to try to find the new update site. Thanks – Dasmowenator Oct 28 '20 at 19:07
