Bug 2080977

Hi Major,

I don't currently maintain any EPEL packages, and I would like to keep it that way.  I have added you as comaintainer.  Feel free to take any steps you deem necessary.

Be aware that I am working on upgrading antlr4-project to version 4.10.1.  It has some backwards incompatibilities with previous versions, so it is taking me a bit to get all of my ducks in a row, but I hope to do that upgrade sometime in the next month or so, probably in Rawhide only.

Thanks for the quick reply, Jerry! I'll take a closer look at the spec to see what needs to be done to get it built for epel9.

azure-cli wants 4.7.2, so the current 4.9.3 version should be okay for now.

It *looks* like we could use the source from PyPi to make this one fairly simple. Am I oversimplifying this, Jerry, and forgetting about something critical with antlr4?

I'm not clear on what you're asking.  If you mean that you only need the python runtime in EPEL, then sure, just packaging that would simplify your life considerably.

I should add that that won't let you generate any parsers.  You need the (Java) antlr4 package for that.

Thanks, Jerry. That's what I was curious about. After digging through the azure-cli code, it looks like they tell users[0] to download the antlr4 jar and add it to the CLASSPATH manually.

I'll see how deep the dependency tree goes to build antlr4-project in epel9. 🧗🏻‍♂️

Oh boy, after working in COPR for about 20 minutes, I came to realize that this is going to be challenge with a long line of Java dependencies. 🥵

antlr4 is only needed in a couple of small places in azure-cli, so I'll see if I can work around this somehow without needing a long line of backports.

Thanks for helping me understand what's involved, Jerry. 😉
