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.
Saving a pkg-match regex to a temporary variable lets us avoid recomputing it on each
iteration. I didn't benchmark the performance impact, but unless there's a downside to
using `let*` vs `let`, it seems like a no-brainer.
Passing pkg-match to `directory-files` reduces the returned files to those that match the
regex rolling our own reduction.
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.
Misspellings:
"beginnign" changed to "beginning",
"Insert one of several lines" changed to "Insert one or several lines" in two functions,
"identation" changed to "indentation",
Missing comment copied from the function that inserts a line
in the opposite direction:
(defun spacemacs/insert-line-below-no-indent (count)
"Insert a new line below with no indentation."
and renamed the direction, resulting in:
"Insert a new line above with no indentation."
Duplicate comments removed, the comments inside the functions,
are better explanations of what the function does.
Functions reordered:
The functions:
(defun spacemacs/evil-insert-line-below (count)
and
(defun spacemacs/evil-insert-line-above (count)
were written in a illogical order,
the "above" function should be written before the "below" function,
with this change, the function order will match other functions
with "above" and "below" in their names,
for example these:
(defun spacemacs/insert-line-above-no-indent (count)
https://github.com/syl20bnr/spacemacs/blob/develop/layers/%2Bdistributions/spacemacs-base/funcs.el#L535
(defun spacemacs/insert-line-below-no-indent (count)
https://github.com/syl20bnr/spacemacs/blob/develop/layers/%2Bdistributions/spacemacs-base/funcs.el#L549

Can force a check with the universal prefix argument, for instance:
SPC u SPC SPC spacemacs/check-for-new-version
will always check for a new version even if not on master branch.
Once per 24 hours by default.
Caveat: if a new version is detected on the current instance of Emacs
and Emacs is restarted before the end of the 24 hours window then
the new version lighter in the modeline disappear; i.e. we don't
remember the last check results.
Fixes#6692
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.
