There was a edge case with the declaration of the `lsp` layer in `layers.el`
files.
The `hy` layer depends on the `python` layer which in turn depends on the `lsp`
layer if and only if the `python-backend` layer variable is set to `lsp`.
When the `hy` layer was declared first then it declares the `python` layer
without its layer variables, thus the `lsp` layer was not declared because the
`python-backend` variable was not set.
The fix is to gather all the layer dependencies and resolve them only after all
the used layers have been declared.
* new function `configuration-layer/declare-layer-dependencies`
* replace all calls to `configuration-layer/declare-layer` by the new function
except for distribution layers (we declare layer dependencies right away in
distribution layers)
This idea is to have the spacemacs-base distribution only configure defaults for
built-in packages. Those buit-in packages are now configured in the new layer
spacemacs-defaults.
Additionally some other packages of spacemacs-base have been dispatched to
better suiting spacemacs layers.
Projectile has been moved to the new layer spacemacs-project
- Move the following packages to bootsrap distributio layer:
- exec-path-from-shell
- evil-evilified-state
- holy-mode
- hybrid-mode
- spacemacs-theme
- ace-window has been moved to spacemacs-navigation
- centered-buffer-mode has been moved to spacemacs-editing-visual
- pcre2el has been moved to spacemacs-editing
- evil-escape and evil-visualstar have been moved to spacemacs-evil
