The change was introduced by #13059. mocker.el is a large piece of legacy code
that depends on deprecated functionality in EIEIO and cannot be trivially
converted to use `cl-lib` by search and replace.
Problem:
The variable spacemacs-layouts-restrict-spc-tab is defined in:
~/.emacs.d/layers/+spacemacs/spacemacs-layouts/config.el
But the spacemacs-layouts layer isn't loaded by default in spacemacs-base.
Solution:
Check if the variable is bound.
- Removed the first line deletion.
This required the banners to have an empty first line.
- Removed the empty first line from the banners.
- Made sure that there is a single empty line between:
- The Version and Banner.
- Banner and Buttons ([?] [Homepage] ...).
- Version and Buttons (when the banner is hidden).
- Reordered the backend version insertion function call
to match the frontend Spacemacs buffer order.
- version
- banner
- buttons
Before it added:
- the banner
- then the buffers first line was removed
- then the version was added to the first line
- then the buttons were added at the bottom of the buffer
(there are more things added after the buttons,
but they haven't been changed by this commit).
- Removed the version insertion call in:
core/core-spacemacs-buffer.el
The changes above caused the version to appear twice
in the Spacemacs home buffer on startup.
I'm not sure if it has/had other uses.
This seems to be where it was first added to:
core-configuration-layer.el:
core: restore default mode line in home buffer
77161bd591
It was slightly modified in this commit:
core: defer distro insertion in home buffer
cd50d9c069
Here it was joined with the banner:
Fix version injection in home buffer
Don't inject version if banner is nil
a764eb4eb9
core: condensed versions into one string in left-hand side
spacemacs-version@emacs-version (distribution)
627e934453
- I had not seen that the version was joined with the
banner on purpose until now.
It seemed useful to still be able to see the versions
if one just wanted to hide the banner.
Therefore I opened this PR (it's been cherry-picked):
Uncouple version from banner in spacemacs buffer #11901https://github.com/syl20bnr/spacemacs/pull/11901
If there's a good reason to combine them again,
then the changes can be reverted.
The newly introduced function to compile an elpa package
was very much redundant with the existing recompile-elpa function.
I have adapted recompile-elpa so that it can be used for the helm action too.
In addition I have bound recompile-elpa to `SPC c C-c` to allow users to
easily recompile their entire elpa directory if the need arises.
I have also removed the error handling in the helm action in favor of
standard error reporting via the *Compile-Log* buffer.
How to use: `SCP h p` select package then `F3` or `C-z` and choose `Recompile`
Motivation: Some packages when compiling need other packages to be loaded first.
The pacakage maintainers should make sure of this requirement but sommetimes
they don't. It also doesn't help when Spacemacs is lazy loading and compiles
updated pacakges on startup. So the manual fix for this problem is recompile the
package once Spacemacs has fully loaded. This requires user go to the package
install location to delete elc files and then do a `spacemacs/recompile-elpa`.
This commit will do that chore for them.
This will make fixing the problem with `org-plus-contrib` or `dumb-jump` update
every now and then easier.
Fix several problems with environment variable caching.
First, if a shell printed extra output besides the command output,
spacemacs//init-spacemacs-env included the extra output in .spacemacs.env.
For example, a login shell could print a motd, which would be erroneously
included in .spacemacs.env. To avoid this, spacemacs//init-spacemacs-env
now redirects the command output to a temporary file and then reads the
file.
Second, spacemacs//init-spacemacs-env sorted lines using the entire
"name=value" string for each line whereas the correct behavior is to sort
only on the "name" part. To fix this, spacemacs//init-spacemacs-env now
uses sort-regexp-fields with an appropriate regexp to match the "name" part
and ignore the "value" part.
Third, although load-env-vars-set-env added all PATH settings in
.spacemacs.env to exec-path, it set PATH to the first PATH setting in
.spacemacs.env. Now load-env-vars-set-env sets PATH from exec-path so that
it will reflect that combined value.
Fourth, load-env-vars-set-env set exec-path and PATH without consideration
to the operating system's directory separator. Now load-env-vars-set-env
converts backslashes to forward slashes when adding path entries to
exec-path and converts forward slashes to backslashes when setting PATH on
platforms that use backslashes.
Fifth, load-env-vars-set-env now normalizes exec-path by deleting trailing
slashes from path entries, converting drive letters in path entries to
lower-case, and deleting duplicate path entries.
Sixth, Spacemacs no longer uses exec-path-from-shell, but a changelog entry
said that it did. This commit corrects the changelog entry, deletes
another outdated entry, and merges two entries that covered the same
functionality.
Finally, this commit corrects several typos and tries to improve wording in
several docstrings, messages, and comments.
* CHANGELOG.develop: Delete mention of exec-path-from-shell, which
Spacemacs no longer uses by default. Delete mention of
dotspacemacs-import-env-vars-from-shell and
dotspacemacs-import-env-vars-shell-file-name, which no longer exist.
Merge entries about synchronizing environment variables.
* core/core-env.el (spacemacs-ignored-environment-variables): Fix typos and
mention that the strings are regexps that are matched against the names of
environment variables.
(spacemacs//init-spacemacs-env): Use a temporary file rather than standard
output in order to avoid getting motd and other noise. Sort lines using
only environment variables' names, not their values. Better describe the
behavior with respect to spacemacs-ignored-environment-variables, duplicate
settings, and PATH. Try to make wording clearer.
(spacemacs/edit-env): Fix typos in the docstring.
* core/libs/load-env-vars.el (load-env-vars-set-env): Fix typos in the
docstring. Delete trailing slashes from path entries in exec-path, convert
drive letters to lower-case, delete duplicate path entries, and convert
backslashes to forward slashes when setting exec-path. Set PATH from
exec-path, converting forward slashes to backslashes on platforms that use
backslashes.
Sometimes it is useful to go directly to the last error message in the buffer.
This function recursively calls 'spacemacs/next-error until the last error is
reached.
The binding "SPC e l" is associated with it
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)
* modified function configuration-layer//stable-elpa-verify-archive
Add a `fatal-err` variable to handle critical erros that prevent the
verification to be attempted.
Use the function `epg-verify-file` instead of `epg-verify-string` which seems
to give more reliable results.
* modified function configuration-layer//stable-elpa-verify-archive
Gather errors along the verification steps and make a single call to
configuration-layer//stable-elpa-ask-to-continue at the end of the function.
Improve the scope of catched errors so now the users should be prompted when
GPG is not available on the system.
* new function configuration-layer//stable-elpa-disable-repository
* new function configuration-layer//stable-elpa-update-version-file
* new function configuration-layer//stable-elpa-delete-temporary-files
* new function configuration-layer//stable-elpa-ask-to-continue
* new function configuration-layer//stable-elpa-verify-archive
* new function configuration-layer//stable-elpa-disable-repository
* rename function configuration-layer/stable-elpa-download-tarball to
configuration-layer//stable-elpa-download-tarball
* new function configuration-layer/stable-elpa-init
* make the function configuration-layer/stable-elpa-version interactive
configuration-layer/stable-elpa-init is called from init.el.
This function then calls the other new function in more clear fashion than the
previous complicated configuration-layer/stable-elpa-download-tarball
The users are now prompt if they want to install the stable ELPA repository when
the verification of the archive failed.
It is important that the stable elpa download message in the modeline is always
visible to the user as the donwload can take a while depending on the connection
speed.
* new variable configuration-layer-stable-elpa-archive
* add missing sub-directory "packages"
* update .lock file with above changes and bump to archive version 0.400
This reverts commit 5f308b0306.
This message is shown on startup:
spacemacs/startup-hook: Symbol’s value as variable is void: spacemacs-theme-custom-colors
and it broke several things.
Added spacemacs|add-toggle key binding documentation strings:
- To the toggle keys function docstring
- And to it's which-key mouseover minibuffer text
As winner-mode was moved from init.el to dump-init.el winner-mode
was not longer properly started for non-dumped emacs sessions.
Having winner-mode auto activate at startup did fix the issue
for non-dumping users but in turn broke the dumping process.
I have now moved the necessary winner-mode init to
spacemacs/setup-startup-hook which is only called
in the non-dumping case. To allow customizations I activate
winner-mode prior to loading user-init this will allow users
to deactivate winner-mode in the dotfile and fix ediff themselves
if this is wished for.
0ffdb353f9 changed the default config template to use a point size instead of a pixel size. Change the defvar declaration as well.
Commit modified by duianto:
Updated font size in doc/documentation.org
13 and 10.0 are visually the same, because:
- Integer specifies the pixel size.
- Floating-point specifies the point size.
Using a default floating-point size has two benefits:
- It's clear that the font size can be changed by floating-point values.
- There won't be an unpleasant surprise that `13` and `13.0` are different
sizes. For example to make the font slightly larger or smaller than `13`.
Then `10.0` has to be found first by trial and error.
* core/core-funcs.el (spacemacs/alternate-buffer): Instead of using
switch-to-buffer, use set-window-buffer-start-and-point, specifying the
previous window start position and point if known. Replace use of
cl-find-if with cl-find.
* CHANGELOG.develop: Add entry for change to spacemacs/alternate-buffer.
Remove mention of powerline-scale property from the
.spacemacs.template font variable comment.
Update the changelog.develop entry for the mode line
separator scale when the utf-8 separator is used.
Emacs 26 added built-in support for line numbers, relative line numbers, and
visual line numbers. Spacemacs supports only absolute and relative, but there is
no way to access the visual mode. It's hard to get around this, since Spacemacs
abstracts line numbers to a reasonably high degree.
Arguably, `visual` is much more useful than `relative` as a display type. Visual
line numbers are like relative line numbers, but only lines that are actually
showing are counted. This means:
1. Hidden lines are not counted. If a large amount of text is folded, the line
numbers won't jump from "10" to "546". This is particularly useful in
buffers like `magit-status`, where a large amount of information is folded
by default.
2. Lines that are wrapped are counted as multiple lines, since they're being
displayed as multiple lines in the editor. Each visual line will be
numbered - unlike `relative`, where the entire thing is numbered... Once.
With standard relative line numbers, you can't actually navigate using the line
numbers in the sidebar as soon as folded or wrapped lines are introduced. Since
this is one of the main use cases for relative line numbers, this is a big
problem.
Visual mode fixes that problem. Every line that's being displayed is labelled.
Numbers always correspond to the actual number of lines you'd need to navigate
to reach that line.
This commit extends Spacemacs' line number interface to provide visual line
number support.
New var: dotspacemacs-new-empty-buffer-major-mode
Set to a symbol naming a mode (e.g. 'text-mode) to apply that major mode to any
buffers newly created in Spacemacs by spacemacs/new-empty-buffer.
Fixes#12382.
The call to `format-spec` at the end of `spacemacs/title-prepare` creates
a temporary buffer which invokes `buffer-list-update-hook`. This in turn is
caught by treemacs' follow-mode and can lead to an action that requires a
recalculation of the frame-title, which again creates a new temp-buffer, and
so on.
The result is that in some situations Emacs will put full load on a CPU
core while it is idle (though the UI does remain responsive). The disabling
of the hook for the calculation of the frame title prevents this feedback
loop from forming.

Commit 1c4f685b13 replaced
configuration-layer--layers (a list of cfgl-layer objects) with
configuration-layer--used-layers (a list of symbols). It also changed the
configuration-layer/insert-lazy-install-configuration function to use the
new variable, but it did not change the sort predicate. Consequently, the
function started failing:
Wrong type argument: listp, spacemacs-purpose
In addition, because sort is destructive, the function also deleted values
from configuration-layer--used-layers.
This commit fixes the sort predicate so that the function returns the
correct value, and it copies the list before sorting to avoid modifying
configuration-layer--used-layers.
* core/core-configuration-layer.el
(configuration-layer/insert-lazy-install-configuration): Use string<
as the sort predicate, and give sort a copy of the list.
The line in the Spacemacs home buffer that shows the Spacemacs version, Emacs
version and the Spacemacs distribution, for example: "0.300.0@26.1 (spacemacs)"
were tied to the banner. The line disappeared when the banner was hidden.
Fixes a bug where saving a custom variable (e.g. package-selected-packages)
before reading the custom settings from dotspacemacs/emacs-custom-settings could
overwrite the stored settings.
spacemacs/title-prepare is being called on every frame re-display, so
eager evaluation of values for every possible format specifier can be too
expensive. For example projectile-project-name is very slow in TRAMP buffers.
`SPC f e f` key binding is no more present, so moved that table entry to
`SPC h f` in DOCUMENTATION.org.
corrected description of paste transient-state behavior.
Lexical binding is easier to reason about and it's generally recommended for new code. It's faster too.
Dynamic scoping can lead to tricky situations. Example: https://emacs.stackexchange.com/questions/10394/scope-in-lambda
This probably won't break existing code. Most people don't even know the default is dynamic binding.
Since bash will source different files depending on its mode, for instance
login vs. non-login shells, we fetch the env vars from both a login shell and
an interactive non-login shell. We try to cleanup the resulting file by removing
duplicates, sorting env vars etc...

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).
It allows to put package variable with a default value set by spacemacs in
the layer variables. For instance to set treemacs position to the right, you can
now do it like this:
(treemacs :variables treemacs-position 'right)

This allows to navigate between params using the '{' and '}' paragraph movements
and makes it clearer wether description is for the variable below or above.
Since we have now a variable for the mode-line theme, it makes sense to move
the scaling of the mode-line to this variable. Thus the property
=:powerline-scale= of variable dotspacemacs-default-font has been removed and
it is replace by the property =:separator-scale= used in the variable
=dotspacemacs-mode-line-theme=.
This commit also adds a the property =:sperator= for the variable
=dotspacemacs-mode-line-theme= which allows to set the separator type.
Example of the final result:
dotspacemacs-mode-line-theme '(all-the-icons
:separator cup
:separator-scale 1.5)
Documentation has been updated to reflect the changes.
New layer variable `dotspacemacs-mode-line-themes`:
Set the theme for the Spaceline. Supported themes are `spacemacs',
`all-the-icons', `custom', `vim-powerline' and `vanilla'. The first three
are spaceline themes. `vanilla' is default Emacs mode-line. `custom' is a
user defined themes, refer to the DOCUMENTATION.org for more info on how
to create your own spaceline theme."
See DOCUMENTATION.org changes for more info.
This commit adds support for `spaceline-all-the-icons` package.
With this commit, the new loading order for package configuration is:
- pre-init functions for all packages
- init function of all packages
- post-init functions for all packages
Escape left and right bracket character literals to avoid the following
warning:
Loading ‘core-dotspacemacs’: unescaped character literals `?[', `?]' detected!
Delete the quote preceding the lambda in spacemacs|add-toggle to avoid
the following warning:
.emacs.d/core/core-toggle.el: (lambda (x) ...) quoted with ' rather than with #'
While #' would be more correct than ', there is no need to quote the
lambda at all.
Modify macro spacemacs|add-toggle to create additional sets of functions for
each supported modes when the toggle is major mode specific.
A toggle is major mode specific when it is bound to keys using the keyword
:evil-leader-for-mode
Updare documentation to add a section on toggles in the Spacemacs concepts.
- Change nameless prefix to > instead of default :
- Change toggle to SPC m >
- Set nameless separator to nil in order to make it work with any type or separator
- Add diminish unicode ⧁
- Define some default global aliases for Spacemacs source code
- Rename layer variable emacs-lisp-nameless-mode to emacs-lisp-hide-namespace-prefix
- Make variable nameless-current-name safe as a local variable for string values
- Set nameless prefix for core-configuration-layer.el
If non-nil then Spacelpa repository is the primary source to install
a locked version of packages. If nil then Spacemacs will install the lastest
version of packages from MELPA. (default nil)
The default value will be true when we bust all the major bugs.
New variable configuration-layer-elpa-subdirectory set in .lock file.
Now users creating a branch based on develop or master won't reinstall
all the packages in a new elpa directory.
Use const input for function configuration-layer/elpa-directory
New const variables used as input:
- configuration-layer--elpa-root-directory
- configuration-layer--rollback-root-directory
Fix computation of elpa directory by using expand-file-name.
Fixes#9805
New dotfile variable dotspacemacs-verify-spacelpa-archives
Default value is nil for now, users wanting to help testing this feature can
set it to t and delete the directory ~/.emacs.d/.cache/stable-elpa and restart
Emacs to download the Spacelpa archive and verify it.
Update function configuration-layer/stable-elpa-download-tarball to download
signature files as well.
Update function configuration-layer//stable-elpa-untar-archive to verify the
downloaded archive using epg library.
Example of signature files can be found here:
https://github.com/syl20bnr/spacelpa/releases/tag/v0.300
New function spacemacs-buffer/error that gather all the errors and then display
them in the startup buffer under a new list entry `Errors:`.
Add shortcut `e` to go to errors list entry.
New private function configuration-layer//error to wrap spacemacs-buffer/error
and increment the startup error count that is displayed in a red mode-line when
startup process finishes.
Use the official spacelpa ELPA repository.
address: https://github.com/syl20bnr/spacelpa
ELPA repository configuration is now in a file called .lock at the root of the
git repository. Its goal is to setup the ELPA repositories for a given branch
and it should not be modified! The philosophy of Spacemacs is to never fork the
git repository and this lock file has been put in the repo on purpose.
Only the master branch will have a .lock file that points to spacelpa, the
develop branch won't use the stable ELPA repository and will continue to behave
like it always did.
BUT for testing purpose and until the first major version of Spacemacs that uses
the stable ELPA repo is released I push a .lock file to develop branch that
points to spacelpa.
I understand that some people can be annoyed by this so the variable
configuration-layer--elpa-archives can be overriden by putting a setq in your
dotfile in the user-init function like this:
(setq configuration-layer--elpa-archives
'(("melpa" . "melpa.org/packages/")
("org" . "orgmode.org/elpa/")
("gnu" . "elpa.gnu.org/packages/")))
Set it to emacs-version as it is the saner defaults here. When updating the
version of emacs, packages should be byte-recompiled. Thus this is safer to
isolate each package by emacs-version.
Change meaningful values of BACKWARD argument to just nil and non-nil.
Get rid of spacemacs--cycle-themes, it was unnecessary.
Create a defvar for spacemacs--cur-theme.
Original Commit List
- update cycle-spacemacs-theme function to work backward with universal arg

Adds support for setting the following gruvbox theme variants
as dotspacemacs-theme:
- gruvbox-dark-soft
- gruvbox-dark-medium
- gruvbox-dark-hard
- gruvbox-light-soft
- gruvbox-light-medium
- gruvbox-light-hard
The default value is now at the distribution level. The user must put the ivy
layer explicitly in the dotfile.
This to be consistent with filetree package which is neotree by default in
the standard spacemacs distribution.
I'm afraid that we add too much wizard questions as the helm/ivy case will
happen more and more in the future. Neotree and Treemacs are the first layers
to follow the Helm and Ivy pattern. I don't want to add a fourth question to
the wizard which makes it heavy and is not as useful for new users.
Shadowing is now control by layer property ':can-shadow' only.
can-shadow is a commutative relation, if layer1 can shadow layer2 then layer2
can shadow layer1.
the shadow operator is a binary operator accepting two layer names, it is not
commutative and the order of the operands is determined by the order of the
layers in the dotfile (like the ownership stealing mechanism).
If ':can-shadow' is set explicity to nil in the dotfile then the layer won't
shadow any layer.
For instance to install both ivy and helm layer:
(setq dotspacemacs-configuration-layers
'(
ivy
(helm :can-shadow nil)
)
note that due to the commutative relation the above example can also be
written (in this case, ':can-shadow' should be read ':can-be-shawdowed'):
(setq dotspacemacs-configuration-layers
'(
(ivy :can-shadow nil)
helm
)
Layers can now declare in their layers.el file that they shadow one or more
layers using the following functions:
- configuration-layer/shadow-layers
- configuration-layer/shadow-layer
Those function are commutative so:
(configuration-layer/shadow-layer 'layer1 'layer2)
is the same as
(configuration-layer/shadow-layer 'layer2 'layer1)
and means that
layer1 shadows layer2
and
layer2 shadows layer1
The typical use-case is helm and ivy layers. Helm shadows the ivy layer and
Ivy shadows the helm layer.
Shadowing is sensitive to the order of declaration of layers in the dotfile,
for instance:
(setq dotspacemacs-configuration-layers '(
helm
ivy
))
means that ivy shadows helm so helm layer is effectively ignored,
whereas
(setq dotspacemacs-configuration-layers '(
ivy
helm
))
means that helm shadows ivy so ivy layer is effectively ignored.
This mechanism can be turned off using the :can-shadow keyword:
(setq dotspacemacs-configuration-layers '(
ivy
(helm :can-shadow nil)
))
means that both ivy and helm layers will be installed (not recommended in this
case)
Note that the `:can-shadow` mechanism will be fully implemented in a next
commit.
