DEPRECATED: This package is deprecated. Please use package.el.

Technical Notes: Package maintainers assume that the packages they develop will be installed at run-time with package.el. Therefore, they may ask the user for interactive input during installation. I conclude that this makes headless multiplexing difficult, as it is not known until the actual installation.

• Description [[https://raw.githubusercontent.com/conao3/files/master/blob/feather.el/feather-dashboard-teaser.gif]]

feather.el is a wrapper for package.el that supports parallel fetching/byte-compiling.

It have already prepared front end for [[https://github.com/conao3/leaf.el][leaf.el]] in leaf-keywword.el, and you can seamlessly manage Emacs packages with feather.el.

When feather-mode is enabled, feather.el advices package-install in package.el. So, all installation using package.el is handled by feather.el.

feather.el is a package.el wrapper that supports parallel fetch/byte-compilation. When feather-mode is enabled, feather.el sets advice to package-install, handles all package installations, and executes them asynchronously. Originally conceived as a completely new package manager, but in the middle of development it was thought that simply handling package-install would be sufficient to achieve the goal, so it provides your Emacs with a powerful asynchronous installation that preserves the package.el experience.

• Install feather is available via el-get #+begin_src emacs-lisp (leaf feather :el-get conao3/feather.el :config (feather-mode)) #+end_src

• Usage Just enable feather-mode and install some package via package.el (package-install, list-package,,,)

• Notice feather sets the advice to run package-install asynchronously. That is, package-install returns the moment it is executed, and the subsequent S-exp is executed (if any). Therefore, the following configuration will result in an error.

#+begin_src emacs-lisp (package-install 'leaf-keywords) (leaf-keywords-init) #+end_src

If you want execute leaf-keywords-init after leaf-keywords is installed as intended, you need to register an S-exp with father. This allows feather to execute the registered S-exp after the package is installed.

#+begin_src emacs-lisp (package-install 'leaf-keywords) (feather-add-after-installed-hook-sexp leaf-keywords (leaf-keywords-init)) #+end_src

However, this is generally cumbersome, so the easiest solution is to use [[https://github.com/conao3/leaf.el][leaf]]. Using the :feather keyword as a trigger, the S-exp that should be executed after the package is installed is automatically registered with the feather.

#+begin_src emacs-lisp (leaf leaf-keywordsq :feather t :config (leaf-keywords-init)) #+end_src

If you want to switch to a feather install for all the :ensure keywords, you can do so by setting leaf-alias-keyword-alist. With leaf-alias-keyword-alist is ((:ensure . :feather)), the leaf block below has the same meaning as a leaf block using the :feather keyword.

#+begin_src emacs-lisp (leaf leaf-keywords :ensure t :config (leaf-keywords-init)) #+end_src
