I am trying to get tab completion to work while running pdb on OS X 10.10.5. I have installed the homebrew version of python 2.7.13 because it appears (also see this) that Apple does not ship with a functional readline. If I have a trivial script, trivial.py

var1 = "this"
var2 = "is annoying"

and I run /usr/local/bin/python -m pdb trivial.py and on the first entry I enter import readline, rlcompleter; I subsequently can get tab completion. However, if I put in my .pdbrc

import readline
import rlcompleter

tab completion does not work. How is this not the exact same thing? Shouldn't tab completion work when put in my .pdbrc?

I get the same behavior on linux.

ie. with no .pdbrc

$ python3 -m pdb foo.py
(Pdb) in<tab> gives interact
(Pdb) interact
(Pdb) import rlcompleter
(Pdb) in<tab>
(Pdb) in input(  int(

If I have import rlcompleter in my .pdbrc I only get interact when I type in. I get this same result even after I import rlcompleter.

$ python3 -m pdb -c 'import rlcompleter' foo.py

Also prevents tab completion.

Comparing the output of 

$ python3 -vv -m pdb -c 'import rlcompleter' foo.py

and

$ python3 -vv -m pdb foo.py

resulted in a segfault so I would consider this a bug. I suggest you file a bug. Mention something about the import rlcompleter could be missing the Pdb completeionkey=setting being overwritten or the cmd module could be misinitialized. FWIW here is the source I was looking at to gleam some additional info. Pdb source

I found this

Using this method I was able to get the tab completion to work. His code uses a .pdbrc in the source dir and a hidden python script in the home dir. The file has comments where to split the file into two parts.
