Can we specifically rescue NotImplementedError (I'm assuming that's what your handling)? I wouldn't want this to hide a different problem.

I mostly use it to make sure that if something's not working yet in Translation::Ripper that I still see CRuby's Ripper output. When it says "parse_error" that should only hide another problem if I'm expecting a parse error. But if I'm midway through making a modification and it might get an error, this means that "prism ripper" is still useful. I guess I could add a mode that doesn't actually use Prism's Ripper and just prints out CRuby's output without trying Prism?

Ahh that's fine. We can keep it for now, I just want this to go away eventually.

I'm fine having this for now, but we'll definitely want to get rid of this before we close this ticket out.

I'll definitely try. I'm having trouble figuring out when Ripper does and doesn't emit this, even looking through parse.y.

Found a minor TruffleRuby Ripper incompatibility. Turning off that test on Truffle, filed a bug: oracle/truffleruby#3457 |

Turning off the command line test on Windows. Aside from issues like not being able to just run bin/prism (need "ruby bin/prism" or rough equivalent) there's also not a great "which" equivalent. |

Yeah, I'm just removing the command line test. That's annoying, I wanted to add it because the utility broke. But I'm not figuring out how to locate bin/prism to run it reliably, even if I exclude Windows. I can find it in dev checkouts (__dir__ + ../../bin/prism) and in installed gems ( |

Handle more aliases, including fully handling aliases.txt.
As part of handling more aliases, handle symbols that are keywords, constants or operations. Handle interpolated symbols. Handle global variable references.
Better testing of prism ripper CLI and a test for it. I had broken it in renaming Translation::Ripper. Now it's tested.It also prints better output when Prism or Ripper Translation gets an exception during parsing.
