> However it’s really easy to go from a simple shell script running a few commands to something significantly more complex just to do something seemingly simple, like parse a semantic version, make an api call and check the status code etc, etc.
Maybe I keep making the wrong assumption that everyone is using the same tools the same way and thats why my opinions seem very strong. But I wouldn't even think of trying to "parse a semantic version" in shell, I am treating the shell scripts and task runners as plumbing, I would be handing that of a dedicated tool to action.
Let’s say have a folder of tarballs and need to install the latest version. I could reach for an additional “dedicated” tool, get it installed into the CI environment and then incorporate it into the build process, or I could just make a slight modification to my existing shell script and do something like “ls mypkg-*.tar.gz | xargs -n1 | sort -Vr | head -n1” and then move on. But then we start publishing multiple release candidates and now I need to add to that logic to further distinguish between earlier and later rc versions. And so on and so forth…
Now I’m in agreement with you that this is a bad fit for shell scripting, but it is often pragmatic and expedient. And bc there is a cliff between bash and (say) python, some of the time, you’re going to choose the path of least resistance.
Now scale this out to a small team of engineers all facing the same dumb decision of needing to make some tradeoff when they would much rather be writing application logic. The lack of a ubiquitous and robust intermediate language leads to brittle CI fraught with security vulnerabilities.
While the example I provided is a bit contrived, this behavior isn’t hypothetical. I see it everywhere I’ve worked.
Yes I am seeing what your saying, it can start of simple and people will choose the path of least resistance and you'll end up with a ball of mud eventually. Fortunately I have not come across anything that bad yet.
I know it is a made up example, but I am not sure Python would improve the situation. I would be looking at either Docker or SBOMs to try and improve the situation and then hopefully the release process would become a lot simpler.
