The mac port build supports this out of the box, but the version
installed with `brew install emacs --with-cocoa` requires this variable
to be cleared.
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.
Key bindings should not be choosen given a package name, some helm
key bindings are under `SPC h` which are corrected the following way:
SPC h l for helm-resume to SPC r l (resume last completion)
SPC s l for last-search to SPC r s (resume search) (SPC s l is still
available)
SPC h L for helm-locate-library to SPC s L
Resolve#4592
Use mnemonic j for jumping commands. Although some of these commands
exist in other places, they are duplicated here when they don't
conflict.
Add:
1. jb for bookmark-jump
2. jc for avy char jump
3. jd for dired-jump
4. jD for dired-jump-other-window
5. jf for find-function-at-point
6. ji for spacemacs/jump-in-buffer (imenu)
7. jI for helm imenu in all buffers
8. jl for avy go to line
9. ju for avy-pop-mark (u for "undo")
10. jU for spacmacs/avy-goto-url
11. jv for find-variable-at-point
12. jw for avy go to word or subword
Move:
1. jh to j0 (push mark and go to beginning of line)
1. jl to j$ (push mark and go to end of line)
The current way to highlight TODOs is `spacemacs/highlight-TODO-words`
which is a spacemacs' hard-coded function.
This commit changes it for the `hl-todo` package. This imply:
- More keywords are supported out of the box.
- Keywords are associated to faces, so they are shown in different
colors.
- Keywords are stored with their faces in a list, so it's easier for
users to add their own keywords and faces (as contrary to a regexp).
- It is possible to disable highlighting by simply excluding the
package.
I feel that it is not needed because it makes not a lot of sense to
have it non global since it is a dotfile variable.
Also remove ' from the docstring for consistency.
`global-linum-mode` is making line numbers appearing in `*spacemacs*`
and `helm` buffers, what is annoying.
This change make the linum `SPC t n` toggle buffer-local, and add a
customization variable in `.spacemacs` to enable line numbers globally.
«Globally» here as to be understood as «in `prog-mode` and `text-mode`».
