I am looking for an IDE with syntax highlighting, code completion and debugging support to run SageMath 9.0 with preprocessing on (Arch) Linux.
The two most obvious choices seem to be PyCharm and Eclipse, but PyCharm is not able to do from sage.all import *
even though my SAGE_ROOT="/usr"
and I am running pycharm from a sage -sh
as described in https://ask.sagemath.org/question/39742/make-pycharm-recognise-the-sage-python-interpreter/.
