New function configuration-layer/insert-lazy-install-configuration
This function asks for a layer and then insert the lazy configuration
for all the packages owned by this layer.
- New macro `spacemacs|transient-state-format-hint`
Additional hints can be formatted outside of the transient state macro.
This is a better separation of concern from an API point of view
because those hint are coupled to with the usage of :dynamic-hint
keyword. The transient state macro only need to know the entry point
for such dynamic hints, effectively increasing the readability of
transient state definition.
To be able to decouple the formatting of additional hints, a new
private variable whose name is given by the function
`spacemacs//transient-state-props-var-name` has been introduced.
An alternative would have been the save the whole transient state macro
props but a variable allows the cherry-pick only the values we really
need.
- Remove commented code about old variable
`spacemacs-transient-state-title-face`
- Remove unused keyword :entry-binding since it is not used. Given
the number and diversity of transient states in Spacemacs currently it
is a safe guess to remove this keyword for now. We can reintroduce it
later if really needed.
It's not possible to get full backtraces in these instances when an
error is signaled, and I think we should generate full backtraces when
debug-on-error is enabled as a general rule.
I had to make this change at one place to track down the root of problem
2 in #5200.
Bug lurking in the code for quite some time, if both a package and
its dependencies were uninstalled then activation of the dependencies
could fail. This is resolved by explicitly asking package.el to install
the dependencies if required.
Add actions for both helm and ivy.
TODO:
- see TODO in function body
- replace SPC h d p (list all packages, use spacemacs describe when
it is a layer package, otherwise use vanilla describe).
This new keyword allows to add all the packages to the <layer>-packages
even when a package is not toggled on by a given layer variable.
This fixes an issue of the layer system where we had to choose between
discoverability (ie. the list of package in helm or ivy with SPC h SPC)
and installation of package (because any package listed in the variable
<layer>-packages were installed).
Fix bug: When the list of package names returned by
configuration-layer//get-uninstalled-packages contains a package that
isn't contained in configuration-layer--packages, then
configuration-layer//install-package throws "wrong-argument-type:
eieio-object-p nil" error at startup.
configuration-layer//install-packages catches it and prints it in the
home buffer.
New function configuration-layer/lazy-install to add support for
lazy installation of layers based on auto-mode-alist emacs mechanism.
This is essentially the Prelude feature but translated at the layer
level for Spacemacs.
New dotspacemacs variable to enable this feature:
dotspacemacs-enable-lazy-installation
For now this variable is set to nil by default, it will be put to t when
the feature is stable.
POC with elixir layer.
