As a data point, I’ve been using asdf for a few months also. It works like a charm and would be great if I had to manage multiple versions.
I’ve only run into one minor issue. I sometimes use IntelliJ IDEA and it would not recognize asdf’s elixir or erlang installs as valid. I ended up symlinking ~/.asdf/shims/[iex,erl,mix] to /usr/local/bin which quieted IDEA down.
ASDF for everything beside rust. Works great almost out of the box with everything. But it doesn’t work for rust (for me at least) because I couldnt make rustup add component work with asdf, and I need it very much.
I switched to systems elixir for development and have a script which runs tests in docker containers which are mimicking my target system as close as possible.
This does in a certain sense help to keep best practices which are enforced by warnings on a current version (using Funtoo I am mostly up to date) while stil ensuring compatibility with my target system(s).
Nope, but on the other side, I simply removed gemsets all together from 3 repos that used it. As gemset gives no advantages (at least I really can’t see any), and really work only with rvm.
