Two Years of Emacs Solo

Original Article

Hacker News Discussion

📝 Discussion Summary (Click to expand)

1. Personal control & self‑authored extensions

"That means the code is sketchy sometimes, sure, but it's in my control. I wrote it, I understand it, and when it breaks, I know exactly where to look." – wilkystyle

2. Tension over default behaviors & naming

"Because any mention of Emacs must bring out the vi people, just as any mention of vi must bring out the Emacs people. Because you people are cracking your eggs from the wrong end!" – dhosek
"Mind blown. Now I'm wondering if swapping w and W in the config is worth the penalty of diverging from the defaults." – bluebarbet

3. AI‑augmented “Emacs Solo” minimalism

"I always used Emacs, but not, thanks to AI agents, Emacs is better than ever, as it can write the lisp I can't write, and it can read the docs I don't have the time to read." – pqual

🚀 Project Ideas

Emacs Solo Config Generator

Summary- A minimal CLI that converts declarative manifests into a stable, dependency‑free init.el, solving Emacs configuration drift.

  • Core value: One‑click reproducible Emacs setups without external ELPA packages.

Details

Key Value
Target Audience Emacs users who want a minimal, self‑contained config without external ELPA dependencies.
Core Feature CLI that ingests a JSON/YAML manifest of desired behaviors (e.g., backup directory, disabled backups, key bindings) and outputs a ready‑to‑use init.el plus optional .dir-locations files, with comments explaining each setting.
Tech Stack Python 3.11 + Click for CLI, Jinja2 templates for config generation, Markdown docs.
Difficulty Low
Monetization Hobby

Notes

  • HN users repeatedly lament “I don’t want to maintain a 1 000‑line init.el” and fear breaking upgrades when ELPA packages change. This tool automates a stable, declarative config that can be version‑controlled and re‑generated on any machine.
  • Potential for community contributions of manifest presets (e.g., “emacs‑solo‑starter”, “emacs‑no‑backup”) and a hosted template registry.

Expand Region Pro Kit

Summary- A single‑file Emacs Lisp library that adds generic expand‑region‑like functionality for arbitrary delimiter sets, solving the pain of custom expansions.

  • Core value: Easy, shareable token‑pair expansions without pulling in a full package.

Details

Key Value
Target Audience Power users who need custom expand‑region‑like functionality for arbitrary delimiter sets (markdown, code, regex pairs).
Core Feature A lightweight library that provides my/expand-region with a simple DSL to register token pairs (e.g., ("w" . "word"), ("/" . "expr")) and automatically integrates with the built‑in expand-region API.
Tech Stack Emacs Lisp (pure, no dependencies).
Difficulty Medium
Monetization Revenue-ready: {subscription}

Notes

  • The original discussion highlighted a custom function that expands selections based on user‑defined delimiters; many readers wanted a reusable, shareable version. This library would let them publish a tiny .el file on Melpa without maintaining a full package.
  • Could be bundled with a tiny UI (e.g., a M-x my/define-token command) for interactive definition, satisfying the community's desire for discoverable keybinding extensions.

Emacs Upgrade Guardian Service

Summary

  • A webhook that monitors Emacs releases and automatically generates upgrade patches for user configs, eliminating breakage anxiety.
  • Core value: Confidence that future Emacs upgrades won’t silently disable beloved keybindings or variables.

Details

Key Value
Target Audience Emacs users who rely on stable configurations across major Emacs releases and worry about breaking changes in ELPA or built‑in defaults.
Core Feature A lightweight, stateless webhook service that monitors releases on the GNU Emacs Git repository, analyses your public GitHub Gist or repo containing your init.el, and automatically opens a PR (or generates a patch) that updates deprecated variables/settings to their new equivalents, plus a changelog summary.
Tech Stack Node.js (Express) + GitHub Actions API + Docker for isolated testing; optionally a hosted UI for non‑technical users.
Difficulty High
Monetization Revenue-ready: {freemium}

Notes

  • Commenters complained about “changing defaults after 30 years” and “breaking my config on upgrade”. This service would reduce anxiety by automatically preparing upgrade patches, letting users apply them with confidence.
  • Could integrate with CI to test your config in a headless Emacs instance, providing assurance that upgrades won’t silently disable a keybinding you rely on.
