Delete layer evil-cleverparens and move the package to spacemacs-evil layer.
The feature is called "Safe structurral editing" for lisp dialects. Support for
it is added via pre-init functions in each of the concerned layer and proper
documentation is added to their README.org files.
This also removes the recently added package evil-smartparens. The goal is
to choose the best package for evil safe structural editing. For now we use
evil-cleverparens as we supported it first, if evil-smartparens is shown to be
a better package we will be able to switch to it.
This is more dwim in the sense that the normal deleting commands now behave more
like paredit, i.e. region deletion is adjusted to always keep the pairs
balanced.
Group together the which-key entries that call the same command:
k and - becomes k,-
u and _ becomes u,_
Declare a prefix name for SPC x i, this changes the SPC x entry:
from: "i -> +prefix"
to: "i -> +inflection".
Capitalize the transient state title, so that it matches the other TS titles.
Sort the code and documentation key bindings alphabetically.
Choose to inherit from face lazy-highlight instead of region.
Ideally a theme should not set lazy-highlight to the same face as
region.
Also move some function to funcs.el and remove some empty lines.
* layers/+spacemacs/spacemacs-editing/packages.el (spacemacs-editing/init-origami):
add origami package and initialize it
* core/core-dotspacemacs.el (dotspacemacs-override-evil-folding): new
variable to allow choosing between different code folding methods.
Currently supported `evil' and `origami'
By convention, jump back should be on `b`, not `u`
Since `SPC j u` is free, move as well `SPC j U` to `SPC j u`.
`SPC j b` for bookmark jump is already available under `SPC f b`
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.
