Shadowing is now control by layer property ':can-shadow' only.
can-shadow is a commutative relation, if layer1 can shadow layer2 then layer2
can shadow layer1.
the shadow operator is a binary operator accepting two layer names, it is not
commutative and the order of the operands is determined by the order of the
layers in the dotfile (like the ownership stealing mechanism).
If ':can-shadow' is set explicity to nil in the dotfile then the layer won't
shadow any layer.
For instance to install both ivy and helm layer:
(setq dotspacemacs-configuration-layers
'(
ivy
(helm :can-shadow nil)
)
note that due to the commutative relation the above example can also be
written (in this case, ':can-shadow' should be read ':can-be-shawdowed'):
(setq dotspacemacs-configuration-layers
'(
(ivy :can-shadow nil)
helm
)
Layers can now declare in their layers.el file that they shadow one or more
layers using the following functions:
- configuration-layer/shadow-layers
- configuration-layer/shadow-layer
Those function are commutative so:
(configuration-layer/shadow-layer 'layer1 'layer2)
is the same as
(configuration-layer/shadow-layer 'layer2 'layer1)
and means that
layer1 shadows layer2
and
layer2 shadows layer1
The typical use-case is helm and ivy layers. Helm shadows the ivy layer and
Ivy shadows the helm layer.
Shadowing is sensitive to the order of declaration of layers in the dotfile,
for instance:
(setq dotspacemacs-configuration-layers '(
helm
ivy
))
means that ivy shadows helm so helm layer is effectively ignored,
whereas
(setq dotspacemacs-configuration-layers '(
ivy
helm
))
means that helm shadows ivy so ivy layer is effectively ignored.
This mechanism can be turned off using the :can-shadow keyword:
(setq dotspacemacs-configuration-layers '(
ivy
(helm :can-shadow nil)
))
means that both ivy and helm layers will be installed (not recommended in this
case)
Note that the `:can-shadow` mechanism will be fully implemented in a next
commit.
Add two new functions: `spacemacs/transient-state-register-add-bindings`
and `spacemacs/transient-state-register-remove-bindings` to prevent layer
authors and end users from dealing with the underlying variables' subtleties.
Emacs doesn't handle long line lengths very well. If you accidentally rg a file
a file that has very long line lengths it can freeze emacs. This prevents rg
from returning any results with more than 150 characters. Instead, it will
indicate that there were results in that file but they were elided.
The keybinding has changed from `SPC h l` to `SPC r l`; see the changelog, entry
0.200.0 (2016/10/02). So correct the documentation to reflect that.
`SPC h l` is currently bound to `helm-spacemacs-help-layers` (on branch
`develop`).
Add a README.org to the Helm layer to fix `helm-spacemacs-help-layers`
(`SPC h l`). There is little actual documentation -- it just links to
the official docs as well as the Helm wiki and the Helm guide.
Issue #8679
rg tries to be smart about printing line numbers in its output (if running
inside a TTY or not). On Windows, sometimes (always?) it chooses not to print
line number. However, we always want line numbers, so we need to pass -n flag.
Also fix a minor grammar mistake.
Getting FAQ candidates requires org to be loaded which in turn requires to
load magit (via orgit) etc...
This commit moves the FAQ helm source to a new feature helm-spacemacs-faq and
removes the FAQ source from SPC h SPC so the FAQs are only available as a helm
source via SPC h f.
But we have still the FAQ org file entry in SPC h SPC so it is easy to open
the file from the main help key binding.
I find myself wanting to open the package.el and f3 is just too far away
in my keyboard. And I thought maybe this would be something people might
want. Also maybe we could have special binding for actions? like `C-1`
`C-2`, etc
- Apply `/` and `//` rules (double / is for private functions)
- Add missing `spacemacs/` prefixes
- Move functions used outside of spacemacs-base layer to
core/core-funcs.el
- Remove unused functions
Commit originally intented to only rename linum-update-window-scale-fix
to spacemacs/linum-update-window-scale-fix :-)
Fixes some edge cases like SPC f e R performed after SPC h SPC which
could wrongly install or uninstall packages.
Side effects is contained using the variable
configuration-layer--package-properties-read-onlyp, if non nil then
properties value of a package cannot be overwritten.
TL;DR Should get 20~25% speed improvement on startup, should get a big
improvement when using ivy or helm SPC h SPC. Users with layers.el files
in their layers must use `configuration-layer/declare-used-layer`
instead of `configuration-layer/declare-layer`
The implementation of the layer system made heavy use of `object-assoc`
and `object-assoc-list` functions which are not efficient. This PR
mainly replaces those object lists with hash maps in order to index the
objects by their name and achieve an O(1) access time.
The old object lists `configuration-layer--layers` and
`configuration-layer--packages` have been each by two variables each:
- `configuration-layer--indexed-layers` which is a hash-map of all the
layer objects and `configuration-layer--used-layers` which is a list of
all _used_ layers symbols,
- symmetrically `configuration-layer--indexed-packages` which is a
hash-map of all the package objects and
`configuration-layer--used-packages` which is a list of all _used_
packages symbols.
The hash map `configuration-layer--layer-paths` is gone, now we create
directly layer objects when discovering the layers and set the :dir
property. Note that previously the layer paths were the parent directory
of the layer, now :dir is the layer path.
The function `configuration-layer//make-layer` is now similar to its
counterpart `configuration-layer//make-package` in the sense that it
takes an optional `obj` to be able to override its properties.
The functions `configuration-layer/declare-layer` and
`configuration-layer/declare-layers` now takes an optional parameter
`usedp` in order to declare used or not used layers. For convenience
new functions have been added: `configuration-layer/declare-used-layer`
and `configuration-layer/declare-used-layers`, users _must_ update all
occurrences of `configuration-layer/declare-layer` by
`configuration-layer/declare-used-layers` in their `layers.el` files.
`helm-spacemacs-help` and `ivy-spacemacs-help` are updated to match the
changes in `core-configuration-layer.el`.
Rename some variables to make them more explicit:
`configuration-layer-no-layer` -> `configuration-layer-exclude-all-layers`
`configuration-layer-distribution` -> `configuration-layer-force-distribution`
With this new variable, user can load spacemacs anywhere, e.g.
"~/.emacs.d/spacemacs/". Only user's cache directory is still hard-coded
as "~/.emacs.d/.cache/". If user want to use spacemacs this way, drop
one line as the below in "~/.emacs.d/init.el":
(setq spacemacs-start-directory "~/.emacs.d/spacemacs/")
(load-file (concat spacemacs-start-directory "init.el"))
As it was the case during the good old days when spacemacs was still a
baby, SPC h SPC now list correctly all the pre/init/post functions and
the associsted layer. It also now list properly the current owner of
a package so it is easy to find the owner of a package by narrowing
with `packagename owner`.
This new old functionality is possible by leveraging the last
improvements to the layer system (see previous commits).
TODO: update the sources for Ivy
Correctly augment the docstring based on the presence of b,f and /
bindings using dynamic hint.
b,f and / are not available if none of helm or ivy layers are used.
