Ensime seems to be finally dead, as ensime-mode is not longer
available on melpa. The same applies to ob-scala the package
which delivered scala support for org babel.
I have changed the layers default to metals and took care that
ensime is not tried to be installed until it is really selected
as a package.
In addition I have also fixed some smaller issues in the layer
which caused ensime specific settings to be forced even when
metals was selected as a backend.
I have also removed the not longer existing org-babel support
for scala as it requires ob-scala which in turn is based on ensime.
See https://github.com/hvesalai/emacs-scala-mode/issues/155 for details.
Update the version of metals referenced in the metals installation
instructions, so that an old version of the metals binary doesn't get installed
by accident.
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)
problem:
some layer packages lists have the open and closing parentheses on the same line
as the first and last listed package, but most seem to have them on a separate
lines.
solution:
put the open and close parentheses on separate lines, except for lists with only
a single package, they are written on the same line as the variable name and
parentheses.
fix the lists indentation
Replace push with add-to-list in layer init functions and related code.
Modify spacemacs|add-toggle to check for and update an existing toggle in
spacemacs-toggles and only create a new toggle if none already existed.
Replace a conditional push onto erc-packages with use of :toggle.
When initializing which-key, set which-key-replacement-alist to its default
or customized setting before adding all the Spacemacs replacements. We
want to keep the stock replacements but avoid adding duplicates of the
Spacemacs replacements.
Replace the emacs-lisp-mode-hook lambda with a named function to avoid
adding duplicate hooks (which can add duplicate definitions of the
evil-surround pair).
This reverts commit 29c78ce841 and all other fixes
that have been made afterwards.
The motivation is that use-package is seen by many as a replacement for
`require`. Is use-package always defer the loading of packages then is breaks
this use case, this does not respect POLA so even if it was making Spacemacs
loading faster (up to 3s faster on some startup on my machine) we just cannot
use it, it would be irresponsible. Spacemacs should be easy to use, loading
performance will come with time but it is not a priority.
The `scala-enable-eldoc` variable should be used to determine whether or not
ENSIME should print types at point. This makes sure that the hook is only set if
the variable is non-nil.
spacemacs/add-flycheck-hook was not really hooking anything, change the name
to better reflect what it does.
Also changed the push for a add-to-list to avoid duplicates.
