This is a file in org-mode. It contains a mix (a tangle) of explanatory text and source blocks. The source blocks aren’t used directly here, but calling the following function will emit the file
The `header-args` property on line 2 defines where to write the “tangled” output file. The header args are injected into every code block. (Though they can be overridden per block by just specifying a different value for the argument.)
Packages to look into:
- gptel - another form of GPT integration
- auth source - credential management without keeping things in elisp variables
- Copilot.el - Github copilot library for Emacs
- ChatGPT shell - would replace org-ai. Also includes DALL-E shell

From the which-key github repo:
`which-key` is a minor mode for Emacs that displays the key bindings following your currently entered incomplete command (a prefix) in a popup. For example, after enabling the minor mode if you enter C-x and wait for the default of 1 second the minibuffer will expand with all of the available key bindings that follow C-x (or as many as space allows given your settings)
I prefer 0.3 seconds idle delay.

There are some things I keep in my password manager instead of github.
(load-file "~/.passwords.el")I’m using a combination of org-mode, org-roam, Zotero, and citar. Org-mode is for GTD and PARA. Org-roam is for Zettlekasten. Zotero and Citar are for bibliographic references.
Org-mode does double-duty at managing my emacs config, using this very file plus Babel and auto-tangling.
Org-mode is also used (occasionally) for presentations.
Sources and inspirations:
- “Organize Your Life in Plain Text” http://doc.norang.ca/org-mode.html
- Erik Backman’s modern org configuration https://github.com/erikbackman/.emacs.d/blob/223702dd9e0e4452ae97abd98e3962f38fb1ccb4/init.el#L247

GTD is “Getting Things Done”, the classic productivity system from David K. Allen.
PARA is “Projects, Areas, Resources, Archives” from Tiago Forte.
I use GTD for tasks, with PARA for organizing files and artifacts related to each of those categories.

Some of my repeating tasks have checkboxes in them. When I mark these as DONE (and org automatically updates the scheduled date and resets them to TODO) I want to clear the checkboxes so they’re empty on the next occurrence. To do that, I use some code from org-checklist. (I like this ability, but most of org-checklist is about export and printing which I don’t need.) This fragment is courtesy of Yasushi Shoji’s stackoverflow answer.
However, because these are defined before org-mode is (lazily) loaded, I actually add the hook later in the use-package block for org-mode itself.

I use the folloring agenda files:

TODOs in here are habits and should appear in my agenda.resources.orgfor external or third-party resources I haver saved. There should be no tasks in here, so nothing should appear in my agenda. This is a refile target.archives.orgfor completed or canceled projects. TODOs in here are defunct and should not appear in my agenda. This is a refile target.inbox.orgfor braindump items. Nothing should stay in here for long.

I was using org-modern here. But after I had to disable indentation, entity hiding, and keyword fontification… it just wasn’t worth it. Axed it.
I haven’t fully adopted this yet. Most of my work is still in Roam Research. I’m trying this out though and might migrate.
My org-roam nodes are in a separate directory from agenda files. I’m keeping these separate org agendas are fast.

Searching org-roam notes interactively and quickly is surprisingly difficult. I’ve tried Deft and NotDeft… Deft was too slow and NotDeft was too difficult to set up. For the time being, I’m using Xeft, but its setup isn’t great either. It requires a dynamic library that has to be built by hand outside of Emacs.
On first configuration, I will have to compile the Xeft module myself with something like this:
On macOS
brew install xapian
cd ~/.emacs.d/elpa/xeft-3.3
make PREFIX=/opt/homebrewI’m not sure what the Linux equivalent is. I’ll work that out once I’m home from travel.
Once that configuration is done, this block will no longer give errors:
(use-package xeft

(xeft-ignore-extension '("png" "pdf" "jpg" "mp3" "mp4"))
:bind ("C-c a" . xeft))Org-present does a nice job, but I want to customize some of the appearance. The start function sets up the presentation appearance: centered, larger text, visual wrapping, no line numbers, and some font customizations. The `-quit` function restores the original appearance.
Note that there could be some conflict with the theme loaded earlier.

The other customization is to start each slide with subheadings folded. This makes for a nice step-by-step presentation where I can unfold each subhead one at a time.

To execute or export code in org-mode code blocks, you’ll need to set up org-babel-load-languages for each language you’d like to use. This page documents all of the languages that you can use with org-babel.

For example, to insert an empty emacs-lisp block below, you can type <el and press TAB to expand into such a block.
You can add more src block templates below by copying one of the lines and changing the two strings at the end, the first to be the template name and the second to contain the name of the language as it is known by Org Babel.

This snippet adds a hook to org-mode buffers so that efs/org-babel-tangle-config gets executed each time such a buffer gets saved. This function checks to see if the file being saved is the Emacs.org file you’re looking at right now, and if so, automatically exports the configuration here to the associated output files.

This will make it easier to take notes, since I can screenshot presentations or zoom videos and drop the screenshots directly into org instead of fiddling with file locations and manually inserting image links.
At least as of <2023-04-21 Fri> the drag-and-drop feature doesn’t work on my main linux desktop ‘recoil’. I get an elisp error from x-dnd-something-or-other complaining about a broken XDS implementation.
Taking a screenshot with C-M-y does work on ‘recoil’. It probably won’t work on macOS, but I will try that some other day.

send prompts to GPT and insert the results. It can also summarize a
region of text and refactor code.
It does require a secret API token, which I don’t want to put into my dotfiles, so I’ll read it from somewhere else.

Whisper uses OpenAI’s speech to text model to convert audio into a transcript. Before this will work, I must run some commands:
cd ~/.emacs.d/ && git clone git@github.com:natrys/whisper.el.gitIn order for Whisper to work on a Mac we have to do two things. First is some funny business with ffmpeg to figure out which audio input to consume. The following is borrowed from this gist.
(defun rk/get-ffmpeg-device ()
"Gets the list of devices available to ffmpeg.
The output of the ffmpeg command is pretty messy, e.g.
[AVFoundation indev @ 0x7f867f004580] AVFoundation video devices:
[AVFoundation indev @ 0x7f867f004580] [0] FaceTime HD Camera (Built-in)
[AVFoundation indev @ 0x7f867f004580] AVFoundation audio devices:
[AVFoundation indev @ 0x7f867f004580] [0] Cam Link 4K
[AVFoundation indev @ 0x7f867f004580] [1] MacBook Pro Microphone
so we need to parse it to get the list of devices.
The return value contains two lists, one for video devices and one for audio devices.
Each list contains a list of cons cells, where the car is the device number and the cdr is the device name."

The second thing we have to do on a Mac is let macOS know that Emacs needs permission to use the microphone. As of <2024-02-14 Wed>, on Ventura 13.6.4, adding this snippet to /opt/homebrew/Cellar/emacs-plus@29/29.2/Emacs.app/Contents/Info.plist was enough to have macOS prompt me that Emacs wanted permission to use the microphone. It went right in the same section as the mention of NSCameraUsageDescription.
<key>NSMicrophoneUsageDescription</key> <string>Emacs needs permission to access the microphone.</string>

I pretty much only used Freenode, though I did have a couple of nicks for different purposes.

ERC buffers can get pretty big, slowing down other work because they use too much memory. This config limits their max size.
