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.
clojure-defun-style-default-indent has been deprecated in favor of
clojure-indent-style. This is no longer a toggle but one of three
keywords. As it affects the way code is indented, and you should not
need to change your indentation style multiple times while editing, it
should not be a toggle. It's simple enough for the user to setq it to
desired value.
If desired, it may be added back as a completing-read selection (but I
don't think it's necessary).
Error was caused by unnecessarily wrapping cider test fns in
spacemacs//cider-eval-in-repl-no-focus. Test fns do not move focus to
repl anyways, and it caused a wrong-type-argument error.
The added bindings are to more closely match cider bindings (under C-c
C-t). Now spacemacs cider test fns mirror the cider ones.
Hybrid means vim-like in normal and emacs-like in insert. This is a
normal-state compatibility tweak (has no effect on insert-state
bindings), so it belongs.
The previous installation instructions suggested that you install lein
via your OS package manager, but since the minimum required version to
run the plugins is 2.5.2 and some OS package managers are still
packaging versions in 1.x, linking to the official install instructions
is better.
Fixes#5612
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.
`spacemacs` now handles `rainbow-delimiters-mode` by adding it to the
`prog-mode-hook`, if wanted by the user. Some layers are adding it on
their own mode-hook, having for effect that `rainbow-delimiters-mode` is
called twice, which disable it.
This commit remove these layer-specific definitions of
`rainbow-delimiters` as it is now handled by the `spacemacs`
distribution. It also takes care of running `prog-mode-hook` in modes
that are not derived from it.
Fixes#3902
Derived modes don't inherit evil keybindings from their parents, this is
interesting to note, also it would be so great if we could have a
`set-leader-keys` macro that could take a list of modes as well.
evil-set-initial-state is safer than manually adding and deleting from
the lists, because it knows about all available states and ensures that
the mode only shows up in one list. If it is in multiple list the
initial state depends on which is checked first, which we don't want.
Previously, prefixes only worked for `.clj` files, not `.cljs`, `.cljx`,
or `.cljc`. `clojure-mode.el` defines derived major modes for each of
those other filetypes.
In other parts of the clojure layer, `(dolist (m '(...` is used to apply
effects to all of the derived modes, but it was missing from the usage
of `spacemacs/declare-prefix-for-mode`.
`cider-repl-mode` was also added to this list.
clj-refactor defines a list of all available refactorings, along with
the standard two-letter keybindings. Use it, so that spacemacs will get
any added refactorings for free, with no code-change needed in the
clojure layer.
