# Changes
|
||||
|
||||
## 2.4.4
|
||||
|
||||
This release prepares for inclusion to GNU ELPA and includes no other changes
|
||||
|
||||
## 2.4.1
|
||||
|
||||
This is mostly a bug-fix release:
|
||||
|
||||
- Update the documentation for :custom as per #850
|
||||
|
||||
- Fix broken test due to #850
|
||||
|
||||
- better tests
|
||||
|
||||
- add test for #845
|
||||
|
||||
- Support keymap symbol in bind-key. Fix #845
|
||||
|
||||
- use-package-core.el: use the Emacs set-default function to avoid saving :custom vars twice
|
||||
|
||||
- Fix Travis
|
||||
|
||||
- typo, should be a vector, not a bytecode object
|
||||
|
||||
Solves https://github.com/jwiegley/use-package/issues/842
|
||||
|
||||
- Add special value back again, in case needed for backwards compat
|
||||
|
||||
I don't know why this special value exists, but perhaps old client code uses it.
|
||||
|
||||
The additional `t' in the macro expansion is accidental but not harmful I guess.
|
||||
|
||||
- Even when there's no :config, run any pre/post config hooks
|
||||
|
||||
i.e., following the existing docs for use-package-inject-hooks, these hooks are
|
||||
run:
|
||||
|
||||
use-package--foo--pre-config-hook
|
||||
use-package--foo--post-config-hook
|
||||
|
||||
This should make config customisations more predictable (for example, spacemacs
|
||||
uses these hooks extensively to allow 'layers' to be customised).
|
||||
|
||||
I got rid of the "special" default value for :config, because it doesn't seem to
|
||||
be treated any differently than nil.
|
||||
|
||||
Fixes #785
|
||||
|
||||
- Clarify the documentation for :after
|
||||
|
||||
- add table of contents to README
|
||||
|
||||
- Fix typos
|
||||
|
||||
Typos found with codespell.
|
||||
|
||||
- Fix typos
|
||||
|
||||
- Attempt to explain omit "-hook" better
|
||||
|
||||
- Update tests
|
||||
|
||||
- Switch from `require' to `load' + `featurep'
|
||||
|
||||
- Use `require', not `load', when byte-compiling
|
||||
|
||||
- Make custom-face evaluate elisp.
|
||||
|
||||
Fix #696.
|
||||
|
||||
- Add a line of documentation for (use-pacakage ... :hook).
|
||||
|
||||
- Fix typo in README
|
||||
|
||||
- Fix documentation for defer
|
||||
|
||||
- Add no-query option for pdf-tools-install
|
||||
|
||||
- Fix typo in README
|
||||
|
||||
- Fix all notes in README
|
||||
|
||||
- Mention use-package-ensure in README
|
||||
|
||||
Without requiring `use-package-ensure`, setting `use-package-always-ensure`
|
||||
did not actually work for me.
|
||||
|
||||
## 2.4
|
||||
|
||||
### Breaking changes
|
||||
|
||||
- `use-package` no longer requires `diminish` as a dependency, allowing people
|
||||
to decide whether they want to use diminish or delight. This means that if
|
||||
you do use diminish, you'll now need to pull it into your configuration
|
||||
before any use of the `:diminish` kewyord. For example:
|
||||
|
||||
``` elisp
|
||||
(use-package diminish :ensure t)
|
||||
```
|
||||
|
||||
- Emacs 24.3 or higher is now a requirement.
|
||||
|
||||
- The `:defer-install` keyword has been removed. It may reappear as an add-on
|
||||
module for use-package in a future release. See issue #442 for more details.
|
||||
|
||||
- There is no longer a `use-package-debug` option, since `use-package-verbose`
|
||||
already has the possible value of `debug`.
|
||||
|
||||
- The ordering of several elements of `use-package-keywords` have changed; if
|
||||
you had previously customized this (or were an extension author adding to
|
||||
this list), you may need to rework your changes.
|
||||
|
||||
- For extension authors, `:commands` should no longer be propagated down for
|
||||
autoloading. See more below.
|
||||
|
||||
### Other changes
|
||||
|
||||
- Upgrade license to GPL 3.
|
||||
|
||||
- If `use-package-verbose` is set to the symbol `debug`, any evaluation errors
|
||||
during package configuration will cause a complete report to be written to a
|
||||
`*use-package*` buffer, including: the text of the error, the `use-package`
|
||||
declaration that caused the error, the post-normalized form of this
|
||||
declaration, and the macro-expanded version (without verbosity-related
|
||||
code). Note that this still does not help if there are parsing errors, which
|
||||
cause Emacs to register a Lisp error at startup time.
|
||||
|
||||
- New customization variable `use-package-deferring-keywords`, mainly intended
|
||||
for use by extension packages, indicates keywords that, if used without
|
||||
`:demand`, cause deferred loading (as if `:defer t` had been specified).
|
||||
|
||||
- The `:ensure` keyword now accepts a specific pinning sub-keyword. For
|
||||
example:
|
||||
|
||||
``` elisp
|
||||
(use-package foo
|
||||
:pin "elpa")
|
||||
```
|
||||
|
||||
This ensure the package `foo` is installed from `"elpa"`.
|
||||
|
||||
``` elisp
|
||||
(use-package foo
|
||||
:ensure bar
|
||||
:ensure (quux :pin "melpa"))
|
||||
```
|
||||
|
||||
This says that `foo` ensures that `bar` is installed, as well as `quux` from
|
||||
`"melpa"`. It does *not* ensure that `foo` is installed, because explicit
|
||||
`:ensure` keywords were given.
|
||||
|
||||
- New `:hook` keyword.
|
||||
|
||||
- New `:catch` keyword. If `t` or `nil`, it enables (the default, see
|
||||
`use-package-defaults`) or disables catching errors at load time in
|
||||
use-package expansions. It can also be a function taking two arguments: the
|
||||
keyword being processed at the time the error was encountered, and the error
|
||||
object (as generated by `condition-case`).
|
||||
|
||||
- New keywords `:custom (foo1 bar1) (foo2 bar2)` etc., and `:custom-face`.
|
||||
|
||||
NOTE: These are only for people who wish to keep customizations with their
|
||||
accompanying use-package declarations. Functionally, the only benefit over
|
||||
using `setq` in a `:config` block is that customizations might execute code
|
||||
when values are assigned. If you currently use `M-x customize-option` and
|
||||
save to a settings file, you do not want to use this option.
|
||||
|
||||
- New `:magic` and `:magic-fallback` keywords.
|
||||
|
||||
- New `:defer-install` keyword.
|
||||
|
||||
- New customization variable `use-package-enable-imenu-support`.
|
||||
|
||||
- New customization variable `use-package-hook-name-suffix`. Any symbols named
|
||||
in `:hook`, or in the CAR of cons cells passed to `:hook`, have this text
|
||||
appended to them as a convenience. If you find yourself using this keyword
|
||||
to add to hooks of different names, or just don't want such appending done,
|
||||
you can change the text to an empty string.
|
||||
|
||||
- New customization variable `use-package-compute-statistics`, and an
|
||||
accompanying command `M-x use-package-report`. See the README for more
|
||||
details.
|
||||
|
||||
- Allow `:diminish` to take no arguments.
|
||||
|
||||
- Support multiple symbols passed to `:after`, and a mini-DSL using `:all` and
|
||||
`:any`.
|
||||
|
||||
- `:mode` and `:interpreter` can now accept `(rx ...)` forms.
|
||||
|
||||
- Using `:load-path` without also using `:ensure` now implies `:ensure nil`.
|
||||
|
||||
- `:bind (:map foo-map ...)` now defers binding in the map until the package
|
||||
has been loaded.
|
||||
|
||||
- Print key bindings for keymaps in `describe-personal-keybindings`.
|
||||
|
||||
- When `use-package-inject-hooks` is non-nil, always fire `:init` and
|
||||
`:config` hooks.
|
||||
|
||||
- Documentation added for the `:after`, `:defer-install`, `:delight`,
|
||||
`:requires`, `:when` and `:unless` keywords.
|
||||
|
||||
- `:requires SYM` is subtly different from `:if (featurep SYM)`, in that it
|
||||
happens before the `:preface`. This means that using `:requires` will cause
|
||||
definitions in the `:preface` to not be visible to the byte-compiler,
|
||||
leading to possible warnings about unknown functions, or functions that may
|
||||
not be available at run-time (which can generally be ignored, since
|
||||
`:requires` is intended as a check for basic system functionality; `:after`
|
||||
should be used to check for the presence of other modules).
|
||||
|
||||
- New undocumented (and currently experimental) keyword `:load` may be used to
|
||||
change the name of the actual package loaded, rather than the package name,
|
||||
and may even add other names. For example: `(use-package auctex :load
|
||||
tex-site)`. This keyword is used internally to generate the `require` for a
|
||||
package, so that deferral is simply a matter of not generating this keyword.
|
||||
|
||||
- The source code is now broken into several files, so that certain optional
|
||||
features (diminish, delight, ensure) may be maintained separately from the
|
||||
core functionality.
|
||||
|
||||
- When using the `:after` keyword, now even autoloadeds keybinding are
|
||||
deferred until after that other package has loaded, in order to allow
|
||||
convenient `:bind` to maps only present in that other package. Consider the
|
||||
following:
|
||||
|
||||
``` elisp
|
||||
(use-package helm-descbinds
|
||||
:load-path "site-lisp/helm-descbinds"
|
||||
:after helm
|
||||
:bind ("C-h b" . helm-descbinds)
|
||||
:init
|
||||
(fset 'describe-bindings 'helm-descbinds))
|
||||
```
|
||||
|
||||
The binding of `C-h b` here will not occur until helm is loaded; and after
|
||||
it is loaded, `helm-descbinds` itself is not loaded until the user presses
|
||||
`C-h b`.
|
||||
|
||||
- For extension authors, if you add a keyword to `use-package-keywords` whose
|
||||
presence should indicate deferred loading, please also add it to
|
||||
`use-package-deferring-keywords`. Note that this is a bit of a sledgehammer,
|
||||
in that the mere presence of these keywords implies deferred loading. For a
|
||||
more subtle approach, see the new `use-package-autoloads/<KEYWORD>` support
|
||||
mentioned in the next bullet.
|
||||
|
||||
- For extension authors, if you wish deferred loading to possibly occur,
|
||||
create functions named `use-package-autoloads/<KEYWORD>` for each keyword
|
||||
that you define, returning an alist of the form `(SYMBOL . TYPE)` of symbols
|
||||
to be autoloaded. `SYMBOL` should be an interactive function, and `TYPE` the
|
||||
smybol `command`, but this functionality may be extended in future. These
|
||||
autoloads are established if deferred loading is to happen.
|
||||
|
||||
- If you specify a lambda form rather than a function symbol in any of the
|
||||
constructs that *might* introduce autoloads: `:bind`, `:bind*`,
|
||||
`:interpreter`, `:mode`, `:magic`, `:magic-fallback`, and `:hook`: then
|
||||
deferred loading will no longer be implied, since there's nothing to
|
||||
associate an autoload with that could later load the module. In these cases,
|
||||
it will be as if you'd specified `:demand t`, in order to ensure the lambda
|
||||
form is able to execute in the context of the loaded package.
|
||||
|
||||
- For extension authors, there is a new customization variable
|
||||
`use-package-merge-key-alist` that specifies how values passed to multiple
|
||||
occurrences of the same key should be merged into a single value, during
|
||||
normalization of the `use-package` declaration into a proper plist. The
|
||||
default behavior is to simply append the values together (since they are
|
||||
always normalized to lists).
|
||||
|
||||
### Bug fixes
|
||||
|
||||
- Repeating a bind no longer causes duplicates in personal-keybindings.
|
||||
- When byte-compiling, correctly output declare-function directives.
|
||||
- Append to *use-package* when debugging, don't clear it.
|
||||
- Don't allow :commands, :bind, etc., to be given an empty list.
|
||||
- Explicit :defer t should override use-package-always-demand.
