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`
Choose to inherit from face lazy-highlight instead of region.
Ideally a theme should not set lazy-highlight to the same face as
region.
Also move some function to funcs.el and remove some empty lines.
Providing a min-version allows to fetch the elpa version of a built-in
package. For intance to install python mode from GNU elpa, add to
the dotspacemacs-additional-packages:
(python :location elpa :min-version "0.25.2")
This feels weird to set as default a variable using a third-party
service like Dropbox. Was OK when Spacemacs was less popular, now this
variable has nothing to do in this project.
- make it clear that setting dotspacemacs-default-font has no effect in
terminal
- make it clear that it's user responsibility to install Source Code Pro

Random banner choice was broken by the presence of the `img` directory.
Even if `random` was set instead of `random*` in .spacemacs file the
cate banner would still show.
This commit fixes this bug while simplifying the existing code by adding
a regexp filter to only choose "*.txt" files.
Previous behavior, if a micro-state binding had :doc not nil, was an error
Wrong type argument: stringp, 1
Detailed reproduction:
cat > /tmp/test.el <<EOF
(spacemacs|define-micro-state test
:doc "[a] a [b] b [q] quit"
:bindings
("a" nil :doc "a")
("b" nil :doc "b")
("q" nil :doc "quit" :exit t))
(spacemacs/test-micro-state)
EOF
emacs --load /tmp/test.el
Type a, b, or q and see the error in the echo buffer.
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"))
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.
Old implementation excluded package that were not selected, this
implementation does not excluded them, it simply ignore it in the
layer where they are not selected. This reimplementation comes from
a refactor of the way packages.el files are loaded, instead of loading
these files at the moment of resolving the list of used packages, they
are now loaded when making the layer objects. A neat consequence is that
side effects is better confined and the configuration-layer/get-packages
is now pure (at least a lot more pure than before).
In the `cfgl-layer` class the slot `:user-packages` has been renamed
to `:selected-packages` which defaults to `'all` meaning that all
the packages in `:packages` are selected. `:selected-packages` value
is given by the new function `configuration-layer//select-packages`.
Effectively selected packages are given by a new method for `cfgl-layer`
class called `cfgl-layer-get-packages`.
Tests have been updated to reflect the changes.
Also documentation on configuration layer declaration in the dotfile
section of DOCUMENTATION.org has been greatly improved (I hope) and
reflect the last feature added to the
`dotspacemacs-configuration-layers` list.
I had a duplicated layer, but the message that's printed broke spacemacs starting up because it was a format string but wasn't in a `format` form. Simple fix. Spacemacs works again! Yay!
This issue was introduced in c0851ddcb3, according to a quick `git bisect`. :)
