Calling for ruby enthusiasts


I have just released a new version of propane (a stand-alone ruby wrapper for processing), and I would like some help from MacOS and Windows users to test it (works on 64 bit linux). Simple instructions on my blog. Read more about propane here.


Congratulations on the release!

Any particular recommendations for MacOS users installing Java 11 – e.g. with homebrew, jenv etc.? I’m a bit nervous about gumming up my system’s built-in 10 with multiple competing java versions.


I am not sure what to recommend on MacOS but the homebrew jenv route looks sensible. On debian linux I use update-alternatives (that uses symbolic links to manage versions), and if you check jruby version:-

jruby --version

you get when you change to java-11

jruby (2.5.0) 2018-05-24 81156a8 Java HotSpot(TM) 64-Bit Server VM 11.0.1+13-LTS on 11.0.1+13-LTS +jit [linux-x86_64]


jruby (2.5.0) 2018-05-24 81156a8 OpenJDK 64-Bit Server VM 25.181-b13 on 1.8.0_181-8u181-b13-0ubuntu0.18.04.1-b13 +jit [linux-x86_64]

When you switch back with sudo update-alternatives --config java and it is fairly painless.


There finally seems to a bit of interest in getting vanilla processing running on jdk11 (possibly openjdk11). I am aware of PR from @ssilverman and @sampottinger. So I thought it timely to update my propane pre-release version. Which I am very keen for MacOS and Windows users to try out, works fine on linux (if somewhat noisy with warnings of future releases of jdk).
