Had to create dummy init functions at some places since the owner of a package
is the last layer that defines the init function of a package. And a package
can be installed only if it has an owner.
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.
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.
Also remove the check on purpose-mode. Using the purpose layer without
purpose-mode does not make sense so I prefer to throw an error is such
case happens.
Update README.org and add spacemacs-purpose layer to spacemacs
distribution.
Move functions of the layer to funcs.el and prefix variables and
functions introduced by the layer with `spacemacs`.
