+# Description
+
+`leaf.el` is yet another
[use-package](https://github.com/jwiegley/use-package).
+
+`leaf` solves the stress that I feel while using the `use-package` for 2.5
years. By developing from scratch, we have a cleaner and more predictable
implementation than `use-package`.
+
+This makes it easy to maintain and add new keywords. (see
[leaf-keywords.el](https://github.com/conao3/leaf-keywords.el))
+
+`leaf` has keywords almost identical to `use-package`, but some of usage of
the keywords is different.
+
+The quickest way to solve problem is using `macroexpand-1` to see the unfolded
result if it is not what you intended. And also there are also a number of
samples in this README and more in the [test
file](https://github.com/conao3/leaf.el/blob/master/leaf-tests.el).
+
+Currently, `leaf.el` and `leaf-keywords.el` has below rich keywords.
+
+```emacs-lisp
+(leaf-available-keywords)
+;;=> (:disabled
+;; :leaf-protect
+;; :load-path :load-path*
+;; :leaf-autoload

+
+# Install
+
+`leaf.el` and `leaf-keywords.el` can install with package.el from MELPA.
+
+Please put the following code (`<leaf-install-code>` to
`</leaf-install-code>`) to the top of your `init.el`.
+
+Package to be developed
+
+- [feather.el](https://github.com/conao3/feather.el) instead of `package.el`
-> (Achieved! Now available but it is just a pakcage.el wraper)
+
+- leaf-key.el instead of `bind-key` -> (Achieved! Now `leaf` builtin)

+
+
+
+# Usage
+
+Use `leaf` in your init.el like `use-package`.
+
+You declaratively tell the `leaf` to configure the package using special
keywords.
+
+`leaf` converts your declaration into Elisp for Emacs to understand, and Emacs
executes it to configure the package.
+
+
+
+# Customize
+
+- `leaf-defaults`: Default arguments for all leaf-block.
+- `leaf-expand-{{keyword}}`: If nil, not to expand that keyword.
+- `leaf-expand-minimally`: If nil, disable keywords that are not needed for
debugging.
+- `leaf-default-plstore`: default `plstore` stored variable
+- `leaf-alias-keyword-alist`: Alist represents keyword alias. Handle KEY is
alias of VALUE.
+
+```emacs-lisp
+(defcustom leaf-alias-keyword-alist '((:ensure . :package))
+ "The alias keyword. KEY is treated as an alias for VALUE."
+ :type 'sexp
+ :group 'leaf)
+```
+
+This default value means `:ensure` is alias `:package`.
+
+If you want to use `:ensure` as `:feather`, please set this value as
`((:ensure . :feather))`. Please more info related feather is
[here](https://github.com/conao3/feather.el).
+
+
+
+# Syntax
+
+All below examples are excerpts from
[leaf-tests.el](https://github.com/conao3/leaf.el/blob/master/leaf-tests.el).
+
+These examples are defined in the following format. We expect `FORM` will be
expanded to `EXPECT`.
+
+```emacs-lisp
+(cort-deftest-with-macroexpand TESTCASE-NAME
+ '((FORM ; will be expand by `macroexpand-1'
+ EXPECT) ; expect FORM's expansion will be EXPECT (test by
`equal')
+
+ (FORM
+ EXPECT)
+
+ ...))
+
+(cort-deftest-with-macroexpand-let TESTCASE-NAME
+ LETFORM
+ '((FORM ; will be expand by `macroexpand-1' in LETFORM
+ EXPECT) ; expect FORM's expansion will be EXPECT (test by
`equal')
+
+ (FORM
+ EXPECT)
+
+ ...))
+```
+
+
+
+# Basic keywords
+
+
+
+## none (keyword)
+
+**Unlike use-package**, `leaf` will convert to `nil` when used without any
keywords.
+
+```emacs-lisp
+(cort-deftest-with-macroexpand leaf/none
+ '(((leaf leaf)
+ (prog1 'leaf))))
+```
+
+
+
+## :require keyword
+
+If you want to `require`, you must use the `:require` keyword explicitly.
+
+This is ideally the exact opposite of using the `:no-require` keyword in the
`use-package` if you does not want to `require` it.
+
+The leaf's `:require` keyword is powerful, specify `t` to require the package,
and specify multi symbols to `require` all of them.
+
+Since the priority is lower than that of the conditional branch keyword
described later, it is possible to assign whether to `require` or not by the
conditional branch keyword.
+
+```emacs-lisp
+(cort-deftest-with-macroexpand leaf/require
+ '(
+ ;; 't will be converted leaf--name
+ ((leaf leaf
+ :init (leaf-pre-init)
+ :when leaf-workable-p
+ :require t
+ :config (leaf-init))
+ (prog1 'leaf
+ (when leaf-workable-p
+ (leaf-pre-init)
+ (require 'leaf)
+ (leaf-init))))
+
+ ;; 'nil will be just ignored it
+ ((leaf leaf
+ :init (leaf-pre-init)
+ :require nil
+ :config (leaf-init))
+ (prog1 'leaf
+ (leaf-pre-init)
+ (leaf-init)))
+
+ ;; multi symbols will be accepted
+ ((leaf leaf
+ :init (leaf-pre-init)
+ :require leaf leaf-polyfill
+ :config (leaf-init))
+ (prog1 'leaf
+ (leaf-pre-init)
+ (require 'leaf)
+ (require 'leaf-polyfill)
+ (leaf-init)))
+
+ ;; multi keywords will be accepted
+ ((leaf leaf
+ :init (leaf-pre-init)
+ :require t
+ :require leaf-polyfill
+ :config (leaf-init))
+ (prog1 'leaf
+ (leaf-pre-init)
+ (require 'leaf)
+ (require 'leaf-polyfill)
+ (leaf-init)))
+
+ ;; multi symbols in list will be accepted
+ ((leaf leaf
+ :init (leaf-pre-init)
+ :require (leaf leaf-polyfill leaf-sub leaf-subsub)
+ :config (leaf-init))
+ (prog1 'leaf
+ (leaf-pre-init)
+ (require 'leaf)
+ (require 'leaf-polyfill)
+ (require 'leaf-sub)
+ (require 'leaf-subsub)
+ (leaf-init)))))
+```
+
+
+
+## :package, :ensure keywords
+
+`:package` provide `package.el` frontend.
+
+Because [leaf-keywords.el](https://github.com/conao3/leaf-keywords.el) has
`:el-get` keyword, `:package` provide `package.el` frontend.
+
+Since `:ensure` is to use `package.el` by default, `:ensure` and `:package`
produce the same result.
+
+```emacs-lisp
+(cort-deftest-with-macroexpand leaf/ensure
+ '(
+ ;; 't will be converted leaf--name
+ ((leaf leaf
+ :ensure t

+ ;; simple :ensure expandion example
+ ((leaf macrostep :ensure t)
+ (prog1 'macrostep
+ (leaf-handler-package macrostep macrostep nil)))
+
+ ;; `leaf-handler-package' expandion example.
+ ;; If `macrostep' isn't installed, try to install.
+ ;; If fail install, update local cache and retry to install.

+ (error
+ (display-warning 'leaf
+ (format "In `macrostep' block, failed to

+ (error-message-string err)))))))))))
+```
+
+
+
+## :preface, :init, :config keywords
+
+These keywords are provided to directly describe elisp with various settings
that `leaf` does not support.
+
+These keywords are provided to control where the arguments expand,
+
+- `:preface` expands before the conditional branch keywords; `:if`, `when`
and `unless`.
+
+- `:init` expands after the conditional branch keyword before `:require`.
+
+- `:config` expands after `:require`.
+
+You don't need to put `progn` because `leaf` can receive multiple
S-expressions, but you can do so if you prefer it.
+
+```emacs-lisp
+(cort-deftest-with-macroexpand leaf/preface
+ '(
+ ;; sexp will be expanded in order of :preface, :when, :require, :init,
:config.
+ ((leaf leaf
+ :require t
+ :preface (preface-init)
+ :when (some-condition)
+ :init (package-preconfig)
+ :config (package-init))
+ (prog1 'leaf

+ (leaf-pre-init-after)

+ (when
+ (some-condition)
+ (package-preconfig)
+ (require 'leaf)
+ (package-init))))))
+```
+
+
+
+## :defer-config keyword
+
+`:defer-config` is similar to `:config`, but with `eval-after-load` as the
argument.
+
+```emacs-lisp
+(cort-deftest-with-macroexpand leaf/defer-config
+ '(((leaf leaf
+ :init (leaf-pre-init)
+ :defer-config (leaf-init))

+```
+
+
+
+## :commands keyword
+
+`commands` keyword configures `autoload` for its leaf-block name.

+```
+
+
+
+## :bind, :bind\* keywords
+
+`:bind` and `:bind*` provide frontend for keybind manager.
+
+When defined globally, key bindings and their corresponding functions are
specified in dotted pairs.
+
+To set it to a specific map, **place the map name as a keyword or symbol** at
the top of the list.

+## :custom, :custom\*, :custom-face keywords
+
+Now that the proper Elisp packaging practices have become widely known, it is
a best practice to use `custom-set-variables` to customize packages.
+
+**Unlike use-package**, you must specify a dot pair.
+
+You can of course set multiple variables and set the evaluation result of the
S expression to a variable.
+
+The value set to `custom-face` should also be quoed to emphasize uniformity as
`leaf`.

+## :disabled keyword
+
+The `:disabled` keyword provides the ability to temporarily `nil` the output
of that `leaf` block.
+
+You can use multiple values for the `:disabled` keyword, or multiple
`:disabled` keyword, but `:disabled` only respects the value specified at the
top.
+
+It can also be said that old values can be overridden by described above.
+
+As you can see from the internal structure of `:disabled`, you do not need to
pass an exact `t` to convert it to `nil` because it is comparing it by `unless`.
+
+```emacs-lisp

+# Misc keywords
+
+
+
+## :global-minor-mode keyword
+
+`:global-minor-mode` keyword provides a front end to easily enable minor mode.
global-minor-mode is followed by `-mode` and has the custom of being activated
by passing a `1`, so make the possible guesses accordingly.
+
+The former guess, given `t`, the mode in which you want `leaf--name` to be
valid. If `-mode` is not appended to the package name, add `-mode`. For this
reason, a minor mode without `-mode` can not use this keyword. Please use
`:config`.
+
+Minor-mode function is automatically autoload as a `leaf--name` function, but
if you want customize this, you can use cons-cell.

+# System keywords

+System keywords enabled by defalts on all leaf-block.
+
+If you disable temporary, pass these keyword to `nil`, or add `nil` to
`leaf-defaults` to disable all leaf-block or set `leaf-expand-leaf-protect` to
nil.
+
+
+
+## :leaf-protect keyword
+
+If the leaf fails at the top of the configuration file, most of the
configuration file will not be read.
+
+Therefore, it simply reports an error and expands the error-handling block
that moves execution to the next leaf-block.
+
+```emacs-lisp

+
+
+## :leaf-defer keyword
+
+leaf-blocks with `:bind` or `:mode` can often delay loading or configuration
evaluation.
+
+The keywords that enable this feature are defined below and expand as follows
+
+It seems `:leaf-defer nil` same as `:demand t` in `use-package`.
+
+```emacs-lisp
+(defcustom leaf-defer-keywords (cdr '(:dummy
+ :bind :bind*
+ :mode :interpreter :magic :magic-fallback
+ :hook :commands))
+ "Specifies a keyword to perform a deferred load.
+`leaf' blocks are lazily loaded by their package name

+
+ ((leaf leaf
+ :leaf-defer nil
+ :commands leaf
+ :config (leaf-init))
+ (prog1 'leaf
+ (autoload #'leaf "leaf" nil t)
+ (leaf-init)))))
+```
+
+
+
+## :leaf-autoload keyword
+
+For keywords that set functions, `leaf` can auto-expand the autoload
expression enable lazy loading without relying on magic comments, `;;;Autoload`.
+
+In some cases, you may want to disable this auto-expansion. (I can't think of
that case, but it's provided as a function.)
+
+```emacs-lisp
+(cort-deftest-with-macroexpand leaf/leaf-autoload
+ '(((leaf leaf

+```
+
+
+
+## :leaf-defun keyword
+
+Depending on the context, you may find that the function is declared in the
package that is currently being set. Previously, the `declare-function`
statement was explicitly generated for these functions using the: defun
keyword, but this keyword no longer requires that work.
+
+```emacs-lisp
+(cort-deftest-with-macroexpand leaf/leaf-defun

+ :commands annotate-mode

+```
+
+
+
+## leaf-defvar
+
+When binding to a specific map with: bind, the map variable must be explicitly
declared with: defvar. This keyword suppresses byte compiler warnings by
automatically declaring the variable.

+## Contribution
+
+We welcome PR! But It is need sign to FSF.
+
+Travis Cl test `leaf-test.el` with all Emacs version 23 or above.
+
+I think that it is difficult to prepare the environment locally, so I think
that it is good to throw PR and test Travis for the time being! Feel free throw
PR!
+
+`leaf.el` creates the intended elisp code from DSL with a simple mechanism.
+
+It is clear what internal conversion is done and it is also easy to customize
it.
+
+
+
+### leaf.el mechanism
+
+1. Append `leaf-defaults` and `leaf-system-defaults` to `leaf` arguments.
+2. Because `leaf` receives arguments too many format, normalize as plist.
+ 1. Normalize plist by `leaf-normalize-plist`.
+ 2. Sort plist by `leaf-keyword`.
+
+ ```emacs-lisp
+ (:bind
+ ("M-s O" . moccur)
+ (:isearch-mode-map
+ :package isearch
+ ("M-o" . isearch-moccur)
+ ("M-O" . isearch-moccur-all)))
+
+ ;; => (:leaf-protect (t)
+ ;; :leaf-autoload (t)
+ ;; :bind (("M-s O" . moccur)
+ ;; (:isearch-mode-map
+ ;; :package isearch
+ ;; ("M-o" . isearch-moccur)
+ ;; ("M-O" . isearch-moccur-all)))
+ ;; :leaf-defer (t))
+ ```
+3. Run normalizer, and process keyword using below variables
+
+ | Variable Name | Description |
+ |---------------- |-------------------------------------------------- |
+ | `leaf--raw` | The all leaf arguments |
+ | `leaf--name` | The name of leaf-block |
+ | `leaf--key` | The :keyword of current processing |
+ | `leaf--keyname` | The :keyword name as string of current processing |
+ | `leaf--value` | The arguments which is current processed |
+ | `leaf--body` | The result of the following keywords and arguments |
+ | `leaf--rest` | The following keywords and arguments |
+ | `leaf--autoload` | The list of pair `(fn . pkg)` |
+4. Apply the normalized values to the keyword specific normalizer.
+
+ The definition is `leaf-normalize`, overwrite `leaf--value`.
+5. Run conversion process keyword.
+
+ The conversion definition is `leaf-keywords`, overridden `leaf--body`
+6. Wrap finaly `leaf--body` with `prog1`.
+
+
+
+### Adding new keywords
+
+`leaf` normalize argument with `leaf-normalize`, and conversion with
`leaf-keywords`.
+
+So, pushing new element these variable, `leaf` can recognize new keywords.
+
+In [leaf-keywords.el](https://github.com/conao3/leaf-keywords.el), you can see
practical example, and you can PR it.
+
+Note that leaf only contains keywords for packages that come with the Emacs
standard, and that keywords that depend on external packages are added to its
repository.
+
+
+
+## Migration
+
+
+
+### leaf v3.0 to v4.0
+
+1. Drop support Emacs versions lower than Emacs-24.4
+
+ > I used Emacs 23 bundled with MacOS as a reference when determining the
minimum Emacs support for leaf.el. However, MacOS stopped bundling Emacs 23,
and by supporting Emacs 23, the inability to take advantage of most of the
Elisp ecosystem like `package.el`, `cask`, and `ert` made development
inefficient.
+ >
+ > I plan to release leaf.el v3.8 as the last version to support Emacs 23,
and leaf.el as leaf.el v4.0, with Emacs 24 as the smallest version of Emacs.
+ >
+ > If you're using leaf.el with Emacs 23, you probably don't use
package.el, but rather the traditional site-lisp method of using leaf.el.
(package.el dropped Emacs 23 a long time ago) You should be able to continue
using leaf.el as before by downloading version 3.8 from the
[releases](https://github.com/conao3/leaf.el/releases) page.
+
+ We have posted above announcements for more than 1 month and have dropped
support for Emacs versions below 24.4 because of a bug in a global variable
that prevented it from passing tests under Emacs 24.2.
<https://github.com/conao3/leaf.el/runs/515675886>
+
+ Emacs-24.4 is a version with `lexical-binding` support and should be
considered the minimum version supported by the current Emacs packages.
+
+2. Distribute under GPLv3 instead of AGPLv3
+
+ Now `leaf` project distribute under GPLv3 instead of AGPLv3.
+
+
+
+### leaf v2.0 to v3.0
+
+1. Drop bind-key.el support for :bind and feather.el support for :ensure
+
+ To make `leaf` dependent only on packages that are itself and packages
attached to and Emacs, we have removed the back-end selection for `bind-key`
and `leaf-key` for `:bind` and the back-end selection for `package.el`,
`feather.el`, and `el-get` for `:ensure`.
+
+ You should now use the external package specific keywords, such as
`:bind-key` and `:el-get`, `:feather`, defined in
[leaf-keywords.el](https://github.com/conao3/leaf-keywords.el).
+
+ Therefore, the keyword `:ensure` has been changed to `:package`. This has
no effect because we have defined alias.
+
+
+
+### leaf v1.0 to v2.0
+
+1. Change not to `require` by default
+
+ In order to realize the philosophy of "Leaf of setting", we changed it so
as not to `require` by default.
+
+ If you want to request explicitly use the `:require t` flag.
+
+ ```emacs-lisp
+ ;; behavior of leaf v2.0
+ (leaf foo)
+ => (progn)
+
+ (leaf foo :require t)
+ => (progn
+ (require 'foo))
+
+ ;; behavior of leaf v1.0
+ (leaf foo)
+ => (progn
+ (require 'foo))
+
+ (leaf foo :require t)
+ => (progn
+ (require 'foo))
+ ```
