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.
Calling multiple times configuration-layer/make-package appends the
same layers to :owners, :pre-layers and :post-layers slot.
Use object-add-to-list instead of push.
Add some tests and mock some warning messages.
Rename configuration-layers/make-packages to
configuration-layers/make-packages-from-layers
Move all package initialization logic to configuration-layers/make-package
instead of having it split between make-packages and make-package.
Hook semantic is to be used with run-hooks API and run all hooks
sequentially, jump list semantic is different since the running
functions are not guaranteed to be executed so we prefer using regular
list API to manage jump-lists.
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).
See end of this message for important breaking changes.
Previous behavior was to configure any installed package which caused
a lot of bad side effects and could make spacemacs unusable. This
behavior made little sense and does not fit with spacemacs.
This commit fixes this behavior by separating installed packages from
configured packages. In short dostspacemacs-download-packages variable
now only affect package installation. Packages are now configured if and
only if they are effectively *used* (i.e. listed in variable
dotspacemacs-configuration-layers or dotspacemacs-additional-packages).
IMPORTANT CHANGE: functions `configuration-layer/declare-used-layer` and
`configuration-layer/declare-used-layers` have been removed. These
functions have been introduced in develop branch only so the impact
should be minimal.
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.
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`
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")
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"))
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`. :)
The car of :owners is the real owner.
Now we can easily gather the list of all owners of a package.
Also fix unit tests about missing spacemacs-insecure variable.
Revert "Parse CLI args after dotspacemacs/init"
This reverts commit 0a35502de4.
We cannot delay the parsing of CLI params since we need their values
early during the loading process (i.e. debug info).
Replace the previous commit with a new variable `spacemacs-insecure`
which takes the value of --insecure boolean parameter.
