If you want to use a custom ``PYTHONSTARTUP`` file (typically ``$HOME/.pythonrc.py``), you can add this piece of code:: try: from jedi.utils import setup_readline except ImportError: # Fallback to the stdlib readline completer if it is installed. # Taken from http://docs.python.org/2/library/rlcompleter.html print("Jedi is not installed, falling back to readline") try: import readline import rlcompleter readline.parse_and_bind("tab: complete") except ImportError: print("Readline is not installed either. No tab completion is enabled.") else: setup_readline() This will fallback to the readline completer if Jedi is not installed. The readline completer will only complete names in the global namespace, so for example:: ran will complete to ``range``. With Jedi the following code:: range(10).cou will complete to ``range(10).count``, this does not work with the default cPython :mod:`readline` completer. You will also need to add ``export PYTHONSTARTUP=$HOME/.pythonrc.py`` to your shell profile (usually ``.bash_profile`` or ``.profile`` if you use bash). z /tmp/jedi.loga)filenamefilemodelevelcseZdZfddZdS)zsetup_readline..JediRLc s|dkrtjdtzvzPtdtt j g}|j d}td|fdd|D|_ Wn t dtYnXW5tjdXz |j |WStk rYdSXdS) a This complete stuff is pretty weird, a generator would make a lot more sense, but probably due to backwards compatibility this is still the way how it works. The only important part is stuff in the ``state == 0`` flow, everything else has been copied from the ``rlcompleter`` std. library module. rzStart REPL completion: )fuzzyzREPL completions: %scs(g|] }dt|j|jqS)N)lenZ_like_name_lengthZname_with_symbols).0ctext./tmp/pip-unpacked-wheel-ol4ehs9f/jedi/utils.py Ysz;setup_readline..JediRL.complete..zREPL Completion error: N)syspathinsertosgetcwdpoploggingdebugreprr__dict__completematcheserror traceback format_exc IndexError)selfr state interpreterZ completionsrnamespace_moduler rrEs$       z'setup_readline..JediRL.completeN)__name__ __module__ __qualname__rrr$rrJediRLDsr)rNz$Jedi: Module readline not available.z tab: completezset completion-ignore-case onzset show-all-if-unmodifiedzset show-all-if-ambiguous onz&set completion-prefix-display-length 2) READLINE_DEBUGr basicConfigDEBUG rlcompleterreadline ImportErrorprintZ set_completerrparse_and_bindZset_completer_delims)r%rr)r.r/rr$rsetup_readlines&*#      r3cCs8tdd}ddlm}td|}|ddt|DS)z_ Returns a namedtuple of Jedi's version, similar to Python's ``sys.version_info``.
