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.
Add actions for both helm and ivy.
TODO:
- see TODO in function body
- replace SPC h d p (list all packages, use spacemacs describe when
it is a layer package, otherwise use vanilla describe).
Can be used with counsel-git-grep to edit results in an occur buffer.
Handy!
Add wgrep bindings
",w" to enter wgrep mode
",," to commit changes
",a" to abort
counsel: Fix command output for wgrep
wgrep doesn't work with the column number in the command output
- port helm-perspectives
- port persp switch buffer
- port persp-close[kill]-other to use ivy
- layouts-ts: Make help more consistent
- layouts-ts: Reorganize docstring
Instead of one big list, try to organize into sections to make it easier
to find the right key
Introduce hjkl-completion-navigation-functions to hold the functions to
disable and enable hjkl navigation for ivy and/or helm. The hook is run
with args to indicate whether to enable or disable.
If " -- " appears in the search string split the search string on the
first occurrence with everything before treated as args to the search
and everything after treated as part of the regex.
This version of counsel--async-command feels smoother for me. Right now
it is just being used for the search functions. If others like it, I'll
propose it upstream.
SPC h . helm/ivy-spacemacs-help-dotspacemacs
SPC h SPC helm/ivy-spacemacs-help
SPC h f helm/ivy-spacemacs-help-faq
SPC h l helm/ivy-spacemacs-help-layers
SPC h p helm/ivy-spacemacs-help-packages
SPC h r helm/ivy-spacemacs-help-docs
SPC h t helm/ivy-spacemacs-help-toggles
There's not that many commands under `SPC h` so this gives easier access
to these commands. It also makes `SPC h SPC` get you straight to the
docs in both helm and ivy.
