#+TITLE: Emacs Init File
|
|
#+AUTHOR: Daniel Ziltener
|
|
|
|
* Initialization
|
|
|
|
** Requirements
|
|
|
|
Since I am using ~cl-defun~ in this init file, I need to import ~cl-macs~.
|
|
|
|
#+begin_src emacs-lisp
|
|
(require 'cl-macs)
|
|
#+end_src
|
|
|
|
** Personal Information
|
|
|
|
#+NAME: pers-info-table
|
|
| Name | Mail |
|

|
|
|
|
#+begin_src emacs-lisp :var input=pers-info-table
|
|
(let ((row (car input)))
|
|
(setq user-full-name (cl-first row))
|
|
(setq user-mail-address (cl-second row)))
|
|
#+end_src
|
|
|
|
For storage of passwords, I use [[https://www.passwordstore.org/][pass]]: src_emacs-lisp[]{(auth-source-pass-enable)}
|
|
|
|
** Customizations
|
|
|
|
Since this init file is version controlled, and I set all customizations
|
|
myself in =use-package= blocks, I want Emacs to use a separate file
|
|
for authorized =.dir-local= variables and similar stuff.
|
|
|
|
#+begin_src emacs-lisp
|
|
(setq custom-file "~/.emacs.d/custom.el")
|
|
(when (file-exists-p custom-file)
|
|
(load custom-file))
|
|
#+end_src
|
|
|
|
** Package Manager
|
|
|
|
Most packages are being installed using =Guix=, for the few remaining ones that have to be fetched from Git, I use
|
|
[[https://github.com/progfolio/elpaca][Elpaca]].
|
|
|
|
#+begin_src emacs-lisp
|
|
(defvar elpaca-installer-version 0.6)
|
|
(defvar elpaca-directory (expand-file-name "elpaca/" user-emacs-directory))
|
|

:ref nil

|
:files (:defaults "elpaca-test.el" (:exclude "extensions"))
|
|
:build (:not elpaca--activate-package)))
|
|
(let* ((repo (expand-file-name "elpaca/" elpaca-repos-directory))
|
|
(build (expand-file-name "elpaca/" elpaca-builds-directory))
|

(order (cdr elpaca-order))
|
|
(default-directory repo))
|
|
(add-to-list 'load-path (if (file-exists-p build) build repo))
|
|
(unless (file-exists-p repo)
|
|
(make-directory repo t)
|

|

(progn (message "%s" (buffer-string)) (kill-buffer buffer))
|
|
(error "%s" (with-current-buffer buffer (buffer-string))))
|
|
((error) (warn "%s" err) (delete-directory repo 'recursive))))
|

(unless (require 'elpaca-autoloads nil t)
|
|
(require 'elpaca)
|

(elpaca-generate-autoloads "elpaca" repo)
|
|
(load "./elpaca-autoloads")))
|
|
(add-hook 'after-init-hook #'elpaca-process-queues)
|
|
(elpaca `(,@elpaca-order))
|
|
#+end_src
|
|
|
|
A few additional lines are necessary to integrate it with =use-package=:
|
|
#+begin_src emacs-lisp
|
|
(elpaca elpaca-use-package
|
|
(elpaca-use-package-mode)
|
|
(setq elpaca-use-package-by-default nil))
|
|
(elpaca-wait)

#+end_src

* Helper Functions
|
|
|
|
Those are meant to reduce code duplication, and add some basic useful features.
|
|
The first one is a function to create conditional keybindings.
|
|
|
|
#+BEGIN_SRC emacs-lisp
|
|
(cl-defun conditional-keybind
|
|
"Creates a keybinding that checks `filter-fn`. If it succeeds,
|
|
`target-fn` is run, otherwise `fail-fn`. If no fail-fn is given,
|
|
`self-insert-command` is run instead.
|
|
`target-fn` and `fail-fn` must both be interactive."
|
|
(lambda (_prefix)
|
|
(interactive "P")
|
|
(if (funcall filter-fn)
|
|
(call-interactively target-fn)
|
|
(call-interactively fail-fn))))
|
|
