This might be a limitation of the PyDev debugger but would anyone know how to enable tab completion and history like in a plain Python shell in the Eclipse debug Console window?
Pressing tab or the arrow keys just jumps/moves the cursor. PyDev remote debugger is initialized as needed with following code:
from pydevsrc import pydevd;pydevd.settrace('<my ip>', stdoutToServer=True, stderrToServer=True, suspend=True)
