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.
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.
--no-layer: desactive all the layers except the distribution layer
--distribution: allow the change temporarily the distribution
example
Start emacs with spacemacs-base and no layers:
emacs --no-layer --distribution spacemacs-base
New package :step 'bootstrap', this step happens before 'pre' packages.
A new layer names 'spacemacs-bootstrap' gather all the ':step bootstrap'
packages. This layer is special and is always the first element of
the variable 'configuration-layer--layers' which assure that all
bootstrap packages are configured first.
This new layer leverages the configuration layer system, removes the
clutter of package installations in the function 'spacemacs/init' and
isolate the bootstrap packages in one place.
Several things have been fixed:
- correctly set the :lazy-install flag on all packages of a lazy
installed layer
- correctly unset the :lazy-install flag when installing the packages
- sort the packages before installation and configuration
Fixes#5610
Make cfgl-layer-owned-packages return a list of package objects instead
of just package names.
Use this function to correctly excluded non owned package when flagging
package for lazy installation.
Fixes#5608
- only consider distant packages (i.e. requiring an installation)
- remove lazy install flag of a layer if at least one owned package is
already installed
Now Spacemacs will ask for layer installation when opening a file with
a known file type.
The auto-mode-alist entries are added by the file auto-layer.el in
the layers directory.
Easy insert of forms for lazy initialization can be done with the
interactive function configuration-layer//insert-lazy-install-form.
Change default value of dotspacemacs-enable-lazy-installation to t.
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.
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.
Start to isolate the list of packages. Also we want to define packages
function at the top level of an elisp file in order to not prevent
emacs from knowing where the functions are defined.
This commit has a POC made with elfeed and elixir layers.
Addressing #4586. The bug stops Spacemacs from listing rollback slots if
there exists a file (i.e. non-directory) in the rollback directory.
e.g. .emacs.d/.cache/.rollback/.DS_Store (common in OS X)
- Remove extensions template
- Prompt before creating readme (Users creating private layers probably
don't want to create a readme)
- Template out layer author and email address
- Rename LAYERNAME to LAYER_NAME for readability
- Use fallback attributes if user-full-name is unset
- Fix inconsistent Spacemacs capitalization in template
