Emacs Advent Calendar 7: ordeless, embark 1.0 and some bric-a-brac

Stripped-down Embark?
Installing that Embark key series implementation I mentioned above, to get extra actions for key series such binding them to a key or turning them into named keyboard macros.

How do guys 'namespace' calls to functions in the same 'namespace'?
Generally I recommend to maintain all personal code in the form of tiny but proper Elisp libraries. The config just glues everything together using use-package/setup/your-self-baked-macro. See also /u/oantolin's config which uses this style: https://github.com/oantolin/emacs-config. I cannot recommend this enough!
-
How many lines are in your .emacs file?
I have 3720 lines in my configuration. I try to write as much of it as tiny packages that I configure with use-package, just like I do for external packages. (I highly recommend this form of organization) Many of these are only useful to me, but some would be very reasonable to steal, like:
-
[ANN] unpackaged/imenu-eww-headings: Offer HTML headings in EWW buffers with Imenu
I have a slightly different take on this in my configuration, file shr-heading.el. In addition to imenu support I wanted next and previous heading navigation commands. It turns out you then get imenu support for free, since one way you can specify imenu entries is by providing a "goto previous imenu entry" function.

Dragging the region
I wrote a small drag-region package once. You mark a region, turn on drag-region-mode and then your normal motion commands will drag the region along until you turn the minor mode off again. I never tested it with evil.

ecomplete: the Emacs contact manager you were looking for
I'm very happy with ecomplete now, I mostly just need the completion and automatic storing of addresses I write to, as configured in your post. But occasionally I want to remove an address or manually add one, so I wrote a couple of commands to do that which I bind in embark-email-map to + (for adding) and \ (for removing). I don't think I've used these commands directly, always as Embark actions. When I want to add an email to ecomplete I usually have it written in some buffer already. And the command to remove an email I've only ever used from the ecomplete completion interface or from a message buffer after mistakenly having inserted it and realized that's an old address I'll never use again.

Need help integrating a package into consult
I keep some packages in a subdirectory my personal configuration and don't create a separate repo for them. (Also, not every file there is really a package that could be released: some don't follow proper naming conventions, or depend on details of my configuration).

IRS will officially launch free online tax filing service for 2024 tax season
For me, the beauty of Beancount[0] is that it's just text files in Git. There's a web UI I use for generating reports, and a Python API with which I hacked together some import/export scripts, but 99% of my interactions with it are via Emacs[1] and Magit.
A ton of repetitive bookkeeping tasks become so much easier when you can copy and paste, or use keyboard macros or something like multiple-cursors[2], rather than have to click tens or hundreds of times in a GUI. Many years ago I used QuickBooks, and basic tasks like importing a bank statement took at least an order of magnitude longer than they do now.
Having my company's books in Git is also huge when it comes to auditing, concurrency, backups, and figuring out where things went wrong when accounts don't balance. As mentioned in another comment: `git diff` is a really powerful tool and it's awesome to be able to check out the books as they existed at a particular point in time. `git blame` is great for when things don't balance. Writing meaningful commit messages and comments keeps me sane when I try to remember a year later why something is recorded the way it is.
The biggest downside—or advantage, depending on how you look at it—is that there's no default or built-in chart of accounts, so you need a certain level of accounting acumen (or professional advice) to set things up at first. I'm pretty sure GnuCash aims to be more plug-and-play, whereas Beancount is more akin to a programming library that you use to build an accounting system that works for you. I agree with the grandparent commenter, who said that text-based accounting is "the best and most flexible accounting experience I've ever had." But the cost of that flexibility is that a certain level of base knowledge is a prerequisite.

packages/features/settings that slow Emacs down
The original multiple cursors package is amazing for what it is, but it scales very badly. Emacs is efficient when editing at one place at a time (as you'd do normally), and when mc replicates all the edits character-by-character for all the cursors, it does the very opposite of this: many edits all in very different places. It works quite well when using just a few cursors, but going above a dozen of them causes them to be visibly sluggish.

Multiple-cursors error on Emacs 29.0.60
Recently multiple-cursors has been unusable for me on Emacs 29.0.60 (not a release yet). Movements (and possibly other operations) don't work with the following error:

Best way to "process" a large-ish text file?
If you intend to use Emacs for this (as opposed to some external script), you're probably better off using the keyboard macros or a regular search&replace instead of multiple cursors (I assume the Magnars flavor of them). As flexible as they are, they don't scale well and they get exponentially slower the more cursors you have. Having 2500 cursors sounds insane.

If you have never used wgrep with rg.el to rename a function in several files, try it | that will blow your mind
Then, in *rg* buffer, we transform org-link-expand-abbrev into org-link-RENAMED the way we prefer (we have all the Emacs power, some of us might use query-replace, other might use multiple-cursors.el, other iedit, etc.). And so *rg* buffer looks like this:
