Do not assume python... leverage ESS to improve R interaction.
Fix both undo and fontify in the presence of toggling cells (`C-c
C-t`)
Fix and test switching kernels
```
M-x customize-group RET ein-completion
```
Set `Ein:Completion Backend` to `ein:use-none-backend`, Set `State` to
`Save for Future Sessions`.
Also use `featurep` and `with-eval-after-load` to clean up the
subpackage requiring gymnastics.
Coursera appears to kill websockets every minute or so, and I'm
observing firsthand the buggy behaviors described in #356. This PR
cleans up the websocket code and kernel restart logic. Removed
backwards compatibility for the v2 messaging api
as keeping it in the presence of the refactoring would make it more
broken that it already was.
As emacs users we prefer and have the luxury of fuzzy file navigation
via ido and projectile. From a notebook or notebooklist buffer, the commands
`C-c C-f` ein:file-open
`C-c C-o` ein:notebook-open
offer an ido alternative to point and click navigation.
To populate the ido lists, retrieving the content hierarchy is on by
default. Two custom variables determine how wide and deep the content query
probes (currently at 2 levels deep and 6 directories wide). Set both
to zero to turn off.
tkf half finished code to quickly go from local file buffers to notebook
mode via `C-c C-z` or `C-c C-o`. This is now possible. EIN will
start the server from a suitable parent directory of the visited file.
Enable ido completion for `notebooklist-login`.
Remove the albatross `ein-loaddefs.el` in favor of more standard
`ein-autoloads.el` that is not git tracked.
Convenience `make install` from git source (local alternative to
melpa).
Merge the login and open commands (open aliased to login). Add login
tests described in #352.
Attempt to improve user experience by synchronously executing
`ein:jupyter-server-start`. `ein:dev-prefer-deferred` custom variable
allows easy switch to compare sychronous versus old asynchronous behavior.
Use deferred and callbacks instead of `:sync t` for tkf requests which
is known to have issues. Query server attributes once on
notebooklist-open to avoid sequencing issue #176 (but allow Resync).
Under curl backend, a second request for the same "key" as a pending
request will abort the latter, which has resulted in a clobbered
curl-cookie-jar file, so merely warn and don't abort.
Fix#176
Don't think we were handling https:// url's correctly.
Also some code cleanup in ein-connect; fix longstanding bug in ein:load-files,
and tweak default timeout for starting a jupyter session from within emacs.
Make even more unique edit-cell buffer names. Check that an edit-cell-buffer
does not already exits before creating one.
Also try to be even more aggressive in limiting output in backtraces when
debugging ein.
Post Ipython 2.0 there are no longer separate websocket connections for iopub
and shell, they now share the same websocket connect. This is a simple
convenience function for finding the websocket log buffer for the new-style
connection.
Somewhat hackish solution by defadvicing json.el code to
overcome possible bug in said code. Apparently
`json-encode` does not handle nested empty hash tables properly.
ein was incorrectly writing empty metadata as a Null object, which was
causing errors in ipython.
Added a helper function to write json encoding of a notebook to a
temporary buffer to help debug code for encoding nbformat4 json from
cell data.
Progressing back towards having automated testing via travis. Updated
contact info for ein:dev-bug-report-template and updated requirements in
README.rst.
