@windwiny could you add 2.0.0 to .travs.yml so it can be ensured this passes for 2.0?

[windwiny]

@bcardarella Travis use 2.0.0dev? gem occur error.

[bcardarella]

@windwiny you should be able to do something similar to: https://github.com/dockyard/party_foul/blob/master/.travis.yml#L1-L4

[camsong]

👍 hope it can be done quickly

[bcardarella]

@cldwalker thoughts?

@windwiny Thanks for the pull! travis is using 2.0.0-rc1 instead of 2.0.0, probably since they're using an older version of rvm. I ran the tests locally on 2.0 and I did see failure:

I don't mind pulling this in as is but I'm not going to close #47 until at least tests can finish. Thoughts?

It seems like we are running in the same problem as @denofevil, the author of ruby-debug-base19, which is the source of this Pull Request. He opened an issue about this: https://bugs.ruby-lang.org/issues/7259, which happened to be a duplicate of this other one. This last issue has been inactive for the last three months with the status "Third Party Issue" and the comment "Debuggers should use new TracePoint feature now". Apparently there's a new API to be used, so that call to _rb_vm_get_sourceline (there's only one) should be made "the new way". I've been playing around with the code but my knowledge is not enough to fix it... :(

You can still use debugger in spite of this, but some functionality is broken: line numbers seem messed up sometimes and it crashed when I used the backtrace command. Salute.

[deivid-rodriguez]

I'm sorry, I hadn't checked issue #47, where basically everything I said is already said... I'll follow the discussion there...

[windwiny]

@cldwalker Do as you said, i am just test on rubymine5, that look like is work.
@deivid-rodriguez I've been playing around with the code but my knowledge is not enough to fix it... :( ,me too.

[TylerRick]

Thanks for this! It is working for me so far.
