This replaces the older pattern
:toggle (configuration-layer/package-usedp ..)
This implementation ensures that :disabled-for honors dependent packages, i.e.
if package a depends on package b, which is owned by layer c, and layer c is
disabled for layer d, then neither package a nor b will be configured for layer
d. Previously, this was only true for package a, but not b.
This commit also fixes:
- configuration-layer/describe-package now shows which post-init and pre-init
functions are disabled, if any
- Does not recreate all layer objects unconditionally when calling
configuration-layer/discover-layers. Previously, this led to all layers being
recreated after e.g. `SPC h SPC`, without any of the dotfile information.
Since this information is now necessary for
configuration-layer/describe-package, it’s important that we don’t clear the
indexed layers when invoking this function.
A recent change in the `.spacemacs.template` made it so that the
`dotspacemacs-configuration-layers` variable name can be found inside a
comment right before the expression that sets it's value. This makes the
lazy insertion fail to detect the proper place to add lazy loaded
layers.
This fix solves the immediate problem but maybe a better solution can
be found.
If dotspacemacs-auto-generate-layout-names is non-nil, and the user
tries to open a layout in a position that doesn't yet have a layout,
then create a new layout with an automatically generated name.
It is now possible to use package properties like :location in
dotspacemacs-themes.
Added hooks ran at the beginning and end of configuration-layer/sync:
- configuration-layer-pre-sync-hook
- configuration-layer-post-sync-hook
configuration-layer-pre-sync-hook is used to hook the new function
spacemacs//add-theme-packages-to-additional-packages. This new function updates
dotspacemacs--additional-theme-packages variables.
Update documentation to mention the new feature.
Add all theme packages defined in dotspacemacs-themes to the variable
dotspacemacs-additional-packages and delay the application of user theme at the
end of startup (only when user theme cannot be applied at the very beginning
of Emacs startup).
This has nice properties:
- we leverage the layer system to handle the theme packages installation and
cleanup.
- theme packages are automatically owned by the dotfile preventing them from
being garbage collected.
- the protected package mechanism is now obsolete since themes were the last
packages using it. This mechanism may be removed in a near future.
Thanks to TheBB for the initial idea.
New function `dotspacmacs/emacs-custom-settings` wrapping Emacs
custom settings sexps.
`dotspacemacs/emacs-custom-settings` is called just after the user
configuration (`dotspacemacs/user-config`)
Customize cannot write its auto-generated sexps inside a function, to
accomplish this we trick Emacs by setting the custom file to a file
in `.cache` directory, the path to this file is defined by the variable
`spacemacs--custom-file`. At the startup of Emacs we read this file
to insert its content inside the function
`dotspacemacs/emacs-custom-settings` in the dotfile, this is done in the
function `spacemacs/write-custom-settings-to-dotfile`.
I don't think we need to write the custom settings to the dotfile when
exiting Emacs as well, since we do it at startup at the very beginning
(i.e. before actually loading the dotfile) we should be OK.
Fixes#5170
With a nil value for dotspacemacs-switch-to-buffer-prefers-purpose,
switch-to-buffer prefers using the current window, same as vanilla
Emacs. With a non-nil value, switch-to-buffer prefers another window
with the same purpose as the buffer. This affects actions like
spacemacs/alternate-buffer, and opening buffers from Dired.
Rename dotspacemacs-download-packages to dotspacemacs-install-packages
to better reflect the changes in the previous commit.
Also change the value 'used to 'used-only (note that 'used is still
supported for backward compatibility).
For emacs 24.5 packages will be installed in .emacs.d/elpa/24.5, for
emacs 24.4 packages will be installed in .emacs.d/elpa/24.4, etc.
For a user that uses several emacs versions with the same config, the
packages for version X will be in .emacs.d/elpa/X and the packages for
version Y will be in .emacs.d/elpa/Y. This is instead of using the same
.emacs.d/elpa and possibly having copmiled elisp packages the are
incompatible with one of the emacs versions in use.
Rollback directories are also separated by version:
.cache/.rollback/24.5, .cache/.rollback/24.4, etc.
Don't fallback to default init file when SPACMACSDIR is used and
$SPACEMACSDIR/init.el doesn't exist. The file will be created during
the startup process.
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`
- 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
