#+title: Emacs Configuration

#+DRAFT: false
#+PROPERTY: header-args:emacs-lisp :results silent :tangle init.el

* Early startup

These settings have to exist before the first GUI frame is created, so they
tangle into =early-init.el=.

#+begin_src emacs-lisp :tangle early-init.el
;;; early-init.el --- generated from config.org -*- lexical-binding: t; -*-

;;; Commentary:

;; This file is generated from config.org. Do not edit it directly.

;;; Code:

(dolist (parameter '((width . 140)
									 (height . 42)))
	(add-to-list 'default-frame-alist parameter)
	(add-to-list 'initial-frame-alist parameter))
#+end_src

* Bootstrapping

This is the start of the main runtime entry point, which tangles into =init.el=.

#+begin_src emacs-lisp

	(message

* Shared paths and system identity

These definitions set up the shared paths used by the rest of the
configuration, including the Org directory under =~/org/=.

* Editing defaults

This section covers global editing behavior and a few startup-time tuning
choices.

#+begin_src emacs-lisp

* Dired

On macOS, the system =ls= does not support GNU's =--dired= flag. Keeping
Dired on its built-in path avoids noisy directory listing errors when opening
folders from note helpers.

#+begin_src emacs-lisp
  (use-package dired
    :ensure nil
    :custom
    (dired-use-ls-dired nil))
#+end_src

* Minibuffer completion

This keeps completion close to standard Emacs behaviour while improving the
minibuffer prompts used throughout the notes workflow. Vertico provides the
UI, Orderless handles flexible matching, and Marginalia adds lightweight
annotations.

#+begin_src emacs-lisp
  (use-package vertico
    :ensure t
    :pin melpa
    :init
    (vertico-mode 1))

  (use-package orderless
    :ensure t
    :pin melpa
    :custom
    (completion-styles '(orderless basic))
    (completion-category-defaults nil)
    (completion-category-overrides '((file (styles basic partial-completion)))))

  (use-package marginalia
    :ensure t
    :pin melpa
    :after vertico
    :init
    (marginalia-mode 1))
#+end_src

* Notes workflow

This keeps the note-taking system deliberately small. Daily notes stay as plain
Org files in =~/org/daily/=, while longer-lived notes use Denote inside the
same root directory and rely on links for relationships.

** Org foundations

The Org setup establishes the shared directories, ensures the PARA structure is
present at startup, and provides a small helper for opening today's daily note
with the standard section layout already in place. Agenda views stay focused on
PARA notes, so project, area, and resource files can surface TODOs without
pulling in daily or archived notes. A small directory helper keeps PARA
subdirectories easy to create from the minibuffer before capturing into them.

** Capture entry points

Daily capture goes to today's plain Org file. Denote capture uses Denote's own
Org integration so note identity, metadata, and directories stay under Denote's
control rather than custom code. The convenience templates set a few durable
defaults and prompt for subdirectory placement within the relevant PARA root.

** Denote

Denote manages the durable notes. The folder layout reflects lifecycle, while
Denote handles naming, metadata, linking, and retrieval.

#+begin_src emacs-lisp
  (use-package denote
    :ensure t
    :after org
    :bind (("C-c n n" . denote-open-or-create)
           ("C-c n l" . denote-link))
    :config
    (setq denote-directory ss/org-directory
          denote-known-keywords '("area" "project" "person" "meeting" "1on1" "resource" "decision")

* Gptel workflow

This keeps LLM chat available as a small workflow tool inside Emacs. GitHub
Copilot authentication is handled on demand by gptel, so there is no token
plumbing in this file.

#+begin_src emacs-lisp
  (use-package gptel
    :ensure t
  	:init
    (setq gptel-default-mode 'org-mode
  	  gptel-model 'gpt-4o
  	  gptel-backend (gptel-make-gh-copilot "Copilot"))
    :bind (("C-c n g" . gptel)
  	   ("C-c n s" . gptel-send)
  	   ("C-c n r" . gptel-rewrite)
  	   ("C-c n a" . gptel-add)))
