- Introduced new variable `spacemacs-spacemacs-number-of-rollback-slots'
which holds the maximum number of desired rollback slots.
- Introduced functionality to delete oldest rollback slot directories if
total number exceeds the configuration value.
post value for package :step property is both useless and considered
harmful. It would hijack the determinism of the loading order.
'pre value is used very very rarely and I even think it is not even
used since most of the time a package that must be loaded in pre step
is a bootstrap package. But we keep 'pre since it can be useful to
have it for _exceptional_ cases.
While doing the tests I encountered an edge case where a package owned
by the dotfile could be passed either a 'private or 'local location
which is ambiguous (moreover where do we put packages with 'local
location ?).
We remove the ambiguity by removing the 'private value and push the
path ~/.emacs.d/private/local/pkg/ when the owner of a local
package PKG is the dotfile.
When the owner of a local package is a layer then the load path is
in the "local" subdirectory of the layer directory. It adds no value
to use the old 'private location in this case.
When the package already exists, use configuration-layer/make-package
to copy information into the existing package object.
This allows overwriting location, step and excluded, but NOT owner,
pre-layers or post-layers.
Should fix#2849. The new package-delete tries to save changes to the
selected package variable during the update process and this can cause
conflicts with how spacemacs wants to update packages (and even lead to
the .spacemacs file being deleted. This is also unnecessary, because we
are only deleting the packages temporarily to be installed at the next
boot, so there should be no need to update this variable.
This change only affects Emacs 25 users.
Instead of error, show a warning that the unavailable package(s) were
skipped. This should handle situations were a package is temporarily
unavailable from MELPA (or other sources).
Helm seems to treat "!" specially in pattern matching, so having a ! in
the pattern string when traversing directories is problematic. This
change fixes#2737, because as far as I can tell "+" has no special
meaning in a helm pattern.
Of course, we can choose a different character, but I'm fond of "+" as
representing "more layers here".
- Rename contrib directory to layers
- Add new variable dotspacemacs-distribution
- Move spacemacs layer to layers/!distribution
- New layer spacemacs-core in layers/!distribution
- User can now set dotspacemacs-distribution to spacemacs or
spacemacs-core (default spacemacs)
spacemacs-core is very lightweight layer sufficient to build upon
spacemacs.
instead of the downloaded package archive. It fixes a case where
a package maintainer removes a dependency D of a package P and spacemacs
detects it which has the effect of deleting the obsolete package D, but
package-alist is not yet updated, because package-alist is updated only
when P is reinstalled (or upgraded).
Also it is not need to pass a list, example:
```
(setq dotspacemacs-configuration-layers
'((auto-completion :disabled-for org git)))
```
Will disable auto-completion for org and git layers.
Example:
(setq dotspacemacs-configuration-layers
'((auto-completion :disabled-for (org))))
Will not run any org/pre-init-xxx or org/post-init-xxx functions where
xxx is a package owned by the auto-completion layer.
Limitation:
If ownership of an auto-completion package P is stolen by another layer L
then :disabled-for must also be declared with L, otherwise the P will
be configured for org.
(setq dotspacemacs-configuration-layers
'((auto-completion :disabled-for (org))
(L :disabled-for (org)))
The user should not change the default owner of a layer unless really
required (for instance to use his own fork).
- configuration-layer/declare-layers
- configuration-layer/declare-layer
These functions can be used in the config.el file of a layer to add
required layers.
For instance the react layer needs both html and javascript layers.
salt layer needs the yaml layer (see the following commits)
It is now possible to override the recipe in a custom layer.
For instance to override the recipe R for package P in layer L
In a private layer L' put at the end of dotspacemacs-configuration-layers
and listing P with an init function for P, L' becomes the ower of
P and the recipe R' defined in L' overrides the recipe R.
The `package-delete` function refuses to delete a package that is a
depency by default, which prevents the spacemacs update function from
working most of the time.
This commit sets the flag to force deletion for Emacs 25.
