This new variable replace dotspacemacs-delete-orphan-packages
It defines the behaviour of Spacemacs when downloading packages.
Possible values are `used', `used-but-keep-unused' and `all'.
- `used' will download only explicitly used packages and remove any
unused packages as well as their dependencies.
- `used-but-keep-unused' will download only the used packages but won't
delete them if they become unused.
- `all' will download all the packages regardless if they are used or
not and packages won't be deleted by Spacemacs.
Default value is `used`.
The new layer file `layers.el` is used to declared additional layers.
It is like the sibling of packages.el except that for now it does not
take a list (can do this in a futur commit).
The new order for file loading is the following:
layers.el > packages.el > funcs.el > config.el > keybindings.el
Since packages.el relies on some undefined stuff encapsulated
in init functions, it is not meant to be byte compiled. OTOH funcs.el
(where lies most of the computation added by a package config) should
be compilable.
Since we load packages.el very early it is not possible to use
`configuration-layer/package-usedp` in funcs.el.
This commit also fixes the tests.
Add argument `action` as first positional argument, the second
positonal argument is for tests.
Add actions `doc` and `config`, doc works on org files and config works
on configuration file like packages.el.
The special action `all` performs all actions.
Move test files to `test` sub-folder.
Choose between `md5sum` and `md5` (on OS X) executables.
Add a new formatting function `move-packages-to-config` to move
package lists to config.el file.
Change the semantic of the files for a better control over the
configuration (like being able to use package-usedp function to
guard package configuration and function definition).
This is a big change!
The list of packages of the layer must now be placed in config.el
packages.el only contains pre-init, init and post-init functions
Now both packages.el and funcs.el can use
configuration-layer/package-usedp which is much more powerful than
just configuration-layer/layer-usedp.
Also merging into one file the layer variable and the list of packages
make sense (in this case config.el).
It also means that we can quickly load all the packages declared in
all layer for helm and ivy sources by just loading the config.el file.
Expect some regressions introduced by this change, like the helm
and ivy sources, they will be fixed in other commits.
Keep it in a recommendation in the README for the layer. Eval'ing the
custom-set-faces directly in the config makes it difficult to revert the
customizations.
