IPython 5 does no longer use readline and so the emacs integration is
broken. See also
http://ipython.readthedocs.io/en/stable/whatsnew/version5.html#id1Fix#6622 and related to #6580
This also works if different environments have different IPython
versions since the shell parameters are setup on every environment
switch.
These changes will allow users to evaluate hy code in a repl using an
inferior-lisp process. It requires that users have hy installed via pip
in their local python enviornment.
Add smartparens-mode and documentation
I moved the add-hook for smartparens call to
python/post-init-smartparens. Keybindings were also updated to match
the ones for the Inferior REPL process for Python. Also added some
documentation for required hy pacakge, and the keybindings to
README.org.
Helm-flx, which is included as a core package, requires a minimum Emacs
version of 24.4. As it stands attempting to install Spacemacs on Emacs
24.3 or below will break on helm-flx.
According to the conversation in [0] ':' is removed from
electric-indent-chars in python-mode because typing ':' in

with the point at _ indents the third line. This is not happening in
Emacs 24.5 anymore.

This allows python-test-runner to also be a list of either '(nose
pytest) or '(pytest nose) which then calls the correct test runner in
the dispatch functions.
Move all semantic related config to semantic post-init and correctly
fix the error with void function semantic-idle-summary-mode when
opening a python without the semantic layer enabled.
Motivation
While disabling Evil in holy-mode makes its implementation shorter and
sounds elegant on the paper, in practice it puts a big burden on the
configuration parts which need to know if Evil is enable or not. This is
a bad separation of concerns and the bunch of fixes that we were forced
to do in the past weeks shows this issue. Those fixes were about
removing the knowledge of the activation of Evil by implementing new
dispatching functions to be used by layers, this is cumbersome and makes
Spacemacs layer configuration more subtle which is not good. There was
additional bad consequences of the removal of Evil state like the
impossibility to use Evil lisp state or iedit states, or we would have
been forced to implement a temporary activation of Evil which is
awkward.
Instead I reintroduce Evil as the central piece of Spacemacs design thus
Evil is now re-enabled in holy-mode. It provides the abstraction we need
to isolate editing styles and be able to grow the Spacemacs
configuration coverage sanely. Layers don't need to check whether the
holy mode is active or not and they don't need to know if Evil is
available (it is always available). We also don't need to write
additional dispatching functions, this is the job of Evil, and I think
it provides everything for this. Ideally configuration layer should be
implemented with only Evil in mind and the holy-mode (and hybrid-mode)
should magically make it work for Emacs style users, for instance we can
freely use `evil-insert-state` anywhere in the code without any guard.
Evil is now even more part of Spacemacs, we can really say that
Spacemacs is Emacs+Evil which is now an indivisible pair. Spacemacs
needed this stable API to continue on the right track.
While these changes should be rather transparent to the user, I'm sorry
for this experimental period, I failed to see all the implications of
such a change, I was just excited about the possibility to make Evil
optional. The reality is that Spacemacs has to embrace it and keep its
strong position on being Emacs+Evil at the core.
Implementation
- insert, motion and normal states are forced to emacs state using an
advice on `evil-insert-state`, `evil-motion-state` and
`evil-normal-state` respectively. These functions can be used freely in
the layer configuration.
- A new general hook `spacemacs-editing-style-hook` allow to hook any
code that need to be configured based on the editing style. Functions
hooked to this hook takes the current style as parameter, this
basically generalize the hook used to setup hjkl navigation bindings.
- ESC has been removed from the emacs state map.
- Revert unneeded changes
- Revert "evil: enter insert-state only from normal-state"
commit bdd702dfbe.
- Revert "avoid being evil in deft with emacs editing style"
commit f3a16f49ed.
Additional changes
All editing style packages have been moved to a layer called
`spacemacs-editing-styles`
Notes
I did not have time to attack hybrid mode, I should be able to do it
later.
It's not possible to get full backtraces in these instances when an
error is signaled, and I think we should generate full backtraces when
debug-on-error is enabled as a general rule.
I had to make this change at one place to track down the root of problem
2 in #5200.
There are keybindings `C-o` and `M-*` to go back already, but it could
be a good idea to add an entry to `SPC m g` (or `, g`) menu where the
other movement commands are.
This reverts commit bddf9de8f1.
When pyenv-auto-set-local-pyenv-version is set to 'on-visit then this
switched the python version when e.g. using jump to definition.
