Breaking EWrapper interface change in API 9.79 beta - tickOptionComputation signature #1

Closed pjlegato closed 4 years ago

pjlegato commented 4 years ago

Just a heads up that the method signature for tickOptionComputation in EWrapper changes in the newer 9.79 beta of twsapi, breaking ib-re-actor with that version

I'm using 9.76 as a workaround for now; recording this in case anyone else runs across this issue.

Updating EWrapper.java in the ib-re-actor source with the new one from 9.79 might fix it.

Trying to load wrapper.clj with 9.79 yields:

good catch thank you - maybe I should include one EWrapper.java per version and then load the right one depending on the version that's imported

Hi Paul can you maybe try the [ewrapperversioning] branch which I just pushed? It will naively look for the twsapi version and reference the right ewrapper file. Also I'm not sure it will work on Windows because it filters on the "/" character.

At the moment I have files for 9.76.01 (original) and 9.80.03. If you still have 9.79 feel free to add to branch

should be fixed with 0.1.2
