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`
Add "smart move end of line" behaviour and add two layer variables
allow for tweaking C-a and C-e behaviours:
- better-defaults-move-to-beginning-of-code-first and
- better-defaults-move-to-end-of-code-first
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.
org-reveal is an extension to org mode that allows exporting of org files as
reveal.js presentations. Since not everyone needs this functionality, the
loading of the package is controlled via the `org-enable-reveal-js` switch,
which, if set to `t` would load the package.
- move evil-org to org layer
- move org-plus-contrib to spacemacs-org layer
- remove toc-org from the list of package for org layer
- give ownership of the org package to org layer
- invent a package named default-org in spacemacs-org layer in order
to let the ownership of org package to org layer
- remove unnecessary :mode keyword in use-package from for org
The https link-type opens the local copies of the Spacemacs documentation files with
the spacemacs/view-org-file function. It supports GitHub style heading links
For example, the link:
https://github.com/syl20bnr/spacemacs/blob/develop/layers/org/README.org#links
Will be handled similary to as if it was:
file:~/.emacs.d/layers/org/README.org::*links
Also the `space-doc' mode will be applied.
Refactored GH style anchor search.
