Dear Arch enthusiasts,
The package extra/java-runtime-common provides a convenient script archlinux-java to handle co-existing JDK/JRE versions. I can use it to switch between different versions of java implementations to accomplish numerous tasks from testing the compatibilities of my programs to running third party applications targeting on different platforms. Now I hope there's also a simple script for the same thing but for python. On the
Python actively encourages you to write the python shebang explicitly either #!/usr/bin/env python2 or #!/usr/bin/env python3 for scripts that are not compatible with one of them. It is no longer practical to make any assumptions about the python version in the (unversioned) python binary, therefore your argument about java doesn't hold. Since the developers themselves support this conclusion [0], there is no reason to still have the symlink and hence we should actually abolish it completely, which I expect to happen in the long run.
Alright. Thanks a lot for the information!
I am not a python user, but in Ruby we can use RVM to change between different Ruby versions. Is not there any tool that do the same thing on python?
