leaf.el is yet another 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)
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.
Currently, leaf.el and leaf-keywords.el has below rich keywords.

All below examples are excerpts from leaf-tests.el.
These examples are defined in the following format. We expect FORM will be expanded to EXPECT.

(prog1 'leaf))))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.

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 quoted to emphasize uniformity as leaf.

The keyword is in the form of :emacs< {{version}}, which is expanded as a conditional expression by analogy with the inequality of Emacs < {{version}}. It can be a string, a number, a quoted string or a number, and only one can be specified.

Wrap finaly
leaf--bodywithprog1.
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, 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.

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, andertmade 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 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-bindingsupport and should be considered the minimum version supported by the current Emacs packages. -

Drop bind-key.el support for :bind and feather.el support for :ensure
To make
leafdependent only on packages that are itself and packages attached to and Emacs, we have removed the back-end selection forbind-keyandleaf-keyfor:bindand the back-end selection forpackage.el,feather.el, andel-getfor:ensure.You should now use the external package specific keywords, such as
:bind-keyand:el-get,:feather, defined in leaf-keywords.el.Therefore, the keyword
:ensurehas been changed to:package. This has no effect because we have defined alias.

Change not to
requireby defaultIn order to realize the philosophy of "Leaf of setting", we changed it so as not to
requireby default.If you want to request explicitly use the
:require tflag.;; 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))

Advice and comments given by Emacs-JP's forum member has been a great help in developing leaf.el.
Thank you very much!!
