Doom Emacs Configuration

I'll fill out the how and why of this all as I figure out what the hell I'm doing. My current Emacs Configuration is a mess of copy and pasted snippet loosely grouped together. There's a fair number of work around, to transient configuration issues that now no longer exist, and more of stuff cribbed off StackOverflow & held together with string & bubble gum. While not yet calling Configuration Bankrupt's, I am going to try to see if I can restructure this technical debt.
This Emacs configuration is written using the Literate Programming (sort of) paradigm (well sort of) proposed by Donald Knuth in 1984, and uses Hlissner's awesome Doom Emacs configuration framework.
While I like Literate Programming, I kind of think that literate configuration is largely a mixed bag. Literate Programming produces often more words then code. For even medium size configurations discoverability & readability of what is happening can be bogged down in the weight of prose explaining the backstory, current thought, moral pondering, pros & cons, and deciding thoughts. This extra cruft potentially makes understanding more through, but at cost of readability & readability is king. As a compromise I'm going to version both to the verbose config.org file and all of the produced configuration files. As an example about that verbosity mentioned prior this entire paragraph could have been skipped.
Document Structure
This section will be the what & how of things. There will no directly tangled code in this section.
Doom Emacs
This is built on top of Hlissner's awesome Doom Emacs configuration frameworks. Configuration is divided into 150 modules, & fair number of convenience functions. Rather than detailing stuff about I'll say to go read FAQs & Index.
Configuration is located in the DOOMDIR directory. This is default value is located is the $HOME/.doom.d directory. Typically this directory contains:
-
init.el - Enabled Doom Modules
-
config.el - General Emacs configuration
-
package.el - Packages to fetch from MELPA, Github, etc.
Additional configuration for scoped functionality will be named as +name.el.
Tangle
This org-mode document works by using tangles. By default Doom's literate config mode adds any #+begin_src blocks into the config.el file1. If you want to tangle to a specific file you pass in a file name.
#+begin_src emacs-lisp :tangle "example.el"
or to disable it tangling for a codeblock set the :tangle property in code block header to no.
#+begin_src orgmode :tangle noNoweb Reference
This document uses noweb reference syntax. This allows us to extract bits of configuration into named codeblocks, which can be interpulated into another code block's variable. For example:
#+NAME: initialization #+BEGIN_SRC emacs-lisp (setq sentence "Never a foot too far, even.") #+END_SRC #+BEGIN_SRC emacs-lisp :noweb yes (reverse sentence) #+END_SRC
will produce
#+BEGIN_SRC emacs-lisp :noweb yes (setq sentence "Never a foot too far, even.") (reverse sentence) #+END_SRC
NOTE: unless you explicitly turn off the named code block will be tangled into config.el. Use the no tangle option if you want to disable this.

Lexical Bindings
There minor but non-zero start time benefits for using Lexical Bindings comments. All files created should start with
;;; config.el -*- lexical-binding: t; -*-
replace config.el with the filename being loaded.
Warn user to modify *.el files directly.

;;; This file is generated via tangles from the config.org file. Do not modify this file.

Tridactyl
I am currently using Firefox with Tridactyl. The editorcmd creates a temporary file & opens it with the editor of choice. The domain is included in the temporary file name. We can use this to set the syntax of the file in question. This likely just be markdown.

The configuration is below is pulled from the template init.example.el provided by doom. This one is based off commit e966249.

;; of our modules are listed, including what flags they support.
;; NOTE Move your cursor over a module's name (or its flags) and press 'K' (or
;; 'C-c c k' for non-vim users) to view its documentation. This works on
;; flags as well (those symbols that start with a plus).
;;
;; Alternatively, press 'gd' (or 'C-c c d') on a module to browse its
;; directory (for easy access to its source code).

(default +bindings +smartparens)Additional Keybinds
Keybinds custom keybinds can be located at $DOOMDIR/+keybinds.el.
(load! "+keybinds")Doom comes with some good keybind macros (see here for why). Documentation for this can be found here, but in broad strokes:
- Start with a
map!macro. You can use - When possible use
:whento limit scope. - Use
:prefixand:prefix-mapwhere possible. - Always use
:descto describe what is being done.
Below is a sample snippet from Rameez Khan's blog (first hit on "doom emacs keybind" using DDG):
(map! :leader
(:prefix-map ("a" . "applications")
(:prefix ("j" . "journal")
:desc "New journal entry" "j" #'org-journal-new-entry
:desc "Search journal entry" "s" #'org-journal-search)))Add the lexical bindings magic comment
;;; +keybinds.el -*- lexical-binding: t; -*-Modification warning message.
<<modification-warning>>Local Leader
Lets set the local leader to ,. We may want to remap this to ; later. Both of these seem to have issues with potential key conflicts with evil-snipe. This seems to primarily exists with regards to org-mode. Github issue can be found here.
(setq doom-localleader-key ",")Roam Keybinds
The standard keybind for getting to Roam's daily capture is pretty long. To capture a Log entry I have to type SPC n r d T l. I want to capture as many logs and goals as possible, so lets shorten this up some.
(map! :leader
(:when (modulep! :lang org +roam2)
(:prefix-map ("r" . "roam")
:desc "Find node" "/" #'org-roam-node-find
:desc "Capture to node" "n" #'org-roam-capture
:desc "Capture Today" "c" #'org-roam-dailies-capture-today
:desc "Goto Today" "t" #'org-roam-dailies-goto-today
)
)
)
:leader r is used by :tools upload for "remote", but since I'm not using this lets just not care about that.
Orgmode
This file will be needed for emacs batch automations, where its not reasonable to start up my entire working env. This file can be located at $DOOMDIR/+orgmode.el.
(load! "+orgmode")Lexical bindings
;;; +orgmode.el -*- lexical-binding: t; -*-Modification warning message.
<<modification-warning>>Importing org
This file may get consumed via emacs batch scripting, so we need ot make sure the orgmode is actually loaded.
(require 'org)Directories
My notes are stored via NextCloud to sync multiple machines. The Nextcloud directory can be located in a couple different location based off the OS that the machine is running, but
Where the NextCloud general sync directory may vary based on machine but notes should always be stored at $HOME/org.
(custom-set-variables '(org-directory "~/org/"))I've tried to organize things based on purpose & this will likely change in the future. The current directory looks like this
~/org ├── .archive ├── .attach ├── Projects ├── Roam ├── Todo └── Work
.archive
Where old files go. See org-archive-subtree for more.
.attach
Stuff that is not an orgmode document.
(setq
org-download-image-dir (concat org-directory ".attach/"))
Projects
I keep a todo.org at the root of each project. These are symlinked into the Projects directory. Nextcloud does not sync symlinked documents.
Roam
All roam docs go here. This is my default note taking system.
(setq
org-roam-directory (concat org-directory "Roam/"))
Todo
Another symlink dir. This is used to populate org agenda files.
(setq org-agenda-files (list (concat org-directory "Todos/" )))
Work
On my work machine I'll symlink this into my Todo
ln -s $HOME/org/Work/todo.org $HOME/org/Todo/work.orgI still want to capture work related notes where ever I am though.
