Python running on a remote connection doesn't know how to find files on the
local machine, apparently, so we take the route instead of sending the contents
of a temporary buffer loaded with the pytools python code to the running kernel.
I am expecting that `ein:completions--prepare-oinfo' will error out depending on
the type of python object we are looking at, so no need to log an error every
time this happens as it will unnecessarily fill the ein log buffer and generate
lots of annoying notifications in the notebook buffer.
EIN tries to build a cached of pdef's for all potential completion symbols. This
is problematic because not all completion symbols have a pdef and can cause
python to throw exceptions in entertaining and hard to catch ways. We take a
liberal approach and ignore anything that throws an exception when we try to
inspect it.
Eldoc support should also be more robust because of these changes as well.
One line change to fix header not updating after cell execution
(keeps saying "Kernel is busy").
The bug does not manifest when running with `ein:debug` true since
EMACS's display loop updates more frequently with debug messages.
In tracking this bug, noticed eldoc support isn't quite there.
`__import__('ein').print_object_info_for(%s)` appears in
`ein-completer` and `ein-pytools`, and is invalid python syntax
afaict. Took a few steps to make it whole, but incomplete.
Really basic support for eldoc, buidling off the oinfo cache code written to
support function annotations for the ein company backend. In theory should also
work the other completion backends, but untested at the moment.
Please see the new variable `ein:completion-backend'. Use this variable to
configure which completion backend to use in ein. Currently we support
auto-complete, company-mode, and jedi using auto-complete.
Only six months late. Jupyter changed callback signature for
complete_request, breaking ein's autocomplete code. Missed this for so
long because I am lazy and almost exclusively used jedi for
autocompletion. Ugh.
* Change the call signature of completer callback, to
pass arguments to completer callback.
* Use expand option to suppress auto expansion when
used as dot-complete.
