Alice's Emacs Mods
Read this BEFORE editing ~/.emacs.d/init.el, suggesting packages, or
explaining why some keybinding does something unexpected. Most surprises
here are intentional and load-bearing.
Shape of the install
Build: emacs-nox 30.2 from Nix store (/nix/store/...emacs-nox-30.2)
Frontend: terminal only — no GUI Emacs. Always assume (display-graphic-p) = nil
Daemons: typically 2–4 running at once (factory, server, claude-crdt, horsin-around, …)
factory = full init.el (the "real" one)
claude-crdt / horsin-around = -Q daemons, started for specific purposes
Heading colors are uniformly#7AA2F7 (light blue) across all 8 levels —
this is intentional via set-face-attribute after org-faces loads.
org-bullets for pretty bullets, org-roam at ~/org-roam/,
org-download for screenshots/yank to ~/org-images/.
C-c a agenda, C-c c capture, C-c n … for org-roam.
org-mcp — exposes org over MCP.
Email = Gnus over Gmail/Workspace
Configured for barton@plurigrid.com via IMAP imap.gmail.com:993 SSL +
SMTP smtp.gmail.com:587 STARTTLS. Auth in ~/.authinfo. Start with
C-c g. Gnus dirs all under ~/.emacs.d/gnus/. Causal-gnus binds C-o
in every Gnus mode.
proof-general + narya — Narya is the active proof assistant
causal-proof binds C-o in proof-mode-map; causal-portal binds
C-o in narya-mode-map so Narya hops live inside the Portal menu.
LLMs in the buffer
chatgpt-shell (xenodium) loaded from ~/.emacs.d/site-lisp/chatgpt-shell
with shell-maker next to it. Uses local MLX server at
http://127.0.0.1:8009 running mlx-community/Olmo-3-1125-32B-4bit
("Olmo-3-32B"). Anthropic key from ANTHROPIC_API_KEY env. OpenAI
key falls back to literal "local".
agent-shell + acp — Agent Client Protocol.
mcp-server-lib, org-mcp — MCP from inside Emacs.
Voice → text on F9
whisper.el (in ~/.emacs.d/site-lisp/) bound to F9:
whisper-cli from flox (NOT auto-installed by whisper.el; whisper-install-whispercpp = nil)
Model: ~/v/ggml-base.en.bin (base.en)
macOS mic: avfoundation :1 (MacBook Pro Mic)
Inserts at point, no timestamps. Custom whisper-command overrides
the default to point at the flox binary + local model.
Keyboard
Caps Lock → F19 → Meta (and F7 fallback for terminals that map
F19→F7). Done via key-translation-map + input-decode-map so it
works in both GUI and terminal frames. The user is on a Kinesis
Advantage 360 + Dvorak.
Don't suggest remapping Caps Lock — already done.
Terminal-specific UI
xterm-mouse-mode on (terminal-only block).
mouse-1 set point, mouse-4/5 scroll, drag copies region.
tab-line-mode global, terminal styling: black bg / white fg, current
tab inverted. C-c <left>/C-c <right> switch tabs.
Tabs grouped by major-mode (tab-line-tabs-mode-buffers).
Tree-sitter (Emacs 30 builtin)
treesit-language-source-alist populated for ~16 languages
(bash, c, cpp, css, go, html, java, js, json, markdown, python, rust, toml,
tsx, typescript, yaml). M-x install-tree-sitter-grammars installs all.
major-mode-remap-alist sends *-mode → *-ts-mode.
Other notable mods
AUCTeX with latexmk -pdf as TeX-command-default, RefTeX on,
cdlatex for both LaTeX and Org math. C-o in bibtex-mode.
ledger-mode wired to hledger (not ledger). Custom reports for
income statement / balance sheet / cash flow / monthly expenses.
Files: *.journal, *.ledger, *.hledger. ob-ledger for org-babel.
undo-tree with persistent history at ~/.emacs.d/undo-tree-hist/.
Auto-save every 100 keys / 30s idle.
crdt loaded — see collaborative-emacs skill for the
Claude-Code ↔ Emacs CRDT setup using socket claude-crdt on port 6531.
clipetty — system clipboard via OSC 52 from TTY frames. Replaces
the broken menu-bar-enable-clipboard button (which sets gui-*
functions that no-op without a window-system frame). Enabled
globally via (after-init . global-clipetty-mode).
Disabled but still present
Emacspeak: commented out due to SwiftMac OGG decode having no
cache → CPU spin. The binaural sound theme is built (see
emacspeak-binaural skill) but the (load-file ...) line is
commented. Re-enable at your own risk.
Things NOT to do
Don't suggest pbcopy/pbpaste shellouts for clipboard — clipetty
already handles this via OSC 52, faster + works over SSH.
Don't add a global #+TODO: config — each org file owns its states.
Don't M-x package-install an alternative to causal-suite — the
plurigrid causal fork supersedes it and adds modes you'd lose.
Don't override interprogram-cut-function directly; let
global-clipetty-mode advise it per-frame.
Don't try to re-enable Emacspeak without first solving the SwiftMac
OGG cache issue (it WILL spin a core).
Don't assume GUI Emacs — there is none.
Don't remove "selected packages" from the customize block at the
bottom of init.el — they're how package-autoremove is governed.
Quick triage
Something doesn't bind on C-o? Check whether the mode hook fired
(with-eval-after-load) and whether causal-<mode> was required.
"menu-bar-enable-clipboard" button doesn't paste? clipetty must be
loaded; check (featurep 'clipetty) and global-clipetty-mode.
Whisper produces nothing? Check that whisper-cli is on PATH (flox
env active), that ~/v/ggml-base.en.bin exists, and that
avfoundation :1 is the right mic index.
Caps Lock not Meta? Verify the terminal sends the F19 escape — some
terminals translate it to F7 instead, both are mapped.
Org-roam DB out of sync? M-x org-roam-db-sync.

Cmd+C → Emacs kill (Ghostty binding)
The user's hard requirement is Cmd+C in terminal Emacs → macOS pasteboard, Cmd+V anywhere. The full chain that delivers this:
Cmd+C in Ghostty
→ Ghostty keybind sends literal M-w (ESC w) to Emacs
→ Emacs runs kill-ring-save on the marked region
→ clipetty advice fires, emits OSC 52 to terminal
→ Ghostty receives OSC 52 and writes selection to macOS pasteboard
→ Cmd+V anywhere on the Mac pastes the killed text
The Ghostty side lives in ~/.config/ghostty/config:
keybind = cmd+c=text:\x1bw
This OVERRIDES Ghostty's default Cmd+C = copy_to_clipboard. Trade-off: you
lose "copy Ghostty's mouse selection on Cmd+C". Workarounds for terminal-text
capture: right-click → Copy, or mouse-drag with copy-on-select = true.
The Emacs side: clipetty must be loaded and global-clipetty-mode on.
Already in init.el; verify with (featurep 'clipetty) and global-clipetty-mode.
Workflow: C-Space to set mark → move cursor → Cmd+C → text on macOS pasteboard.
Things that look like clipboard but aren't
menu-bar-enable-clipboard — the "turn on copy paste" menu button. Sets
interprogram-cut-function to gui-select-text which is a no-op in TTY
frames. clipetty bypasses this entirely. Don't trust the button.
Pressing Cmd+C with no Emacs region marked — sends M-w which kill-ring-saves
an empty region (warning: "The mark is not active now"). Pasteboard unchanged.
This isn't a bug; mark a region first.
Ghostty selection + Cmd+C — no longer copies the terminal selection because
the keybind override redirects Cmd+C to Emacs. Use right-click menu.
Reloading Ghostty config
Cmd+Shift+, reloads Ghostty config in place. If keybinds don't take effect,
fully quit and relaunch Ghostty.
Backups

Color strobe (emacs-strobe-walk skill)
A separate sibling skill at ~/.claude/skills/emacs-strobe-walk/ that drives
every face in the frame from a SplitMix64 chain advanced once per
interaction. Background, foreground, cursor, region, hl-line, mode-line
(active + inactive), fringe, all font-lock-* faces, and org-level-1..8
get retinted on each tick. Strobing, deterministic, reseedable, throttled
(default 40 ms minimum gap).
This is what the horsin-around daemon already runs — it was launched
with -Q -l ~/horsin-around/color-walk.el (and the canonical copy is in the
skill dir). Default seed is #x42D (1069). Commands: M-x horsin/enable,
horsin/disable, horsin/reseed. Variables: horsin/seed, horsin/throttle.
Drop into any new daemon:
emacs --daemon=NAME -l ~/.claude/skills/emacs-strobe-walk/color-walk.el
# or, into a live one:
emacsclient -s NAME -e '(load-file "~/.claude/skills/emacs-strobe-walk/color-walk.el")'
Hooks installed: post-command-hook, server-visit-hook,
server-after-make-frame-hook, plus :after advice on
server-eval-and-print so even emacsclient -e ticks the chain.
Footgun (in the skill, repeating it here): never advise server-process-filter —
it fires on every network byte and deadlocks the daemon. Recovery is kill -9.
Also don't call redraw-display in the tick; force-mode-line-update t is
enough and won't block on a tty frame.
Composes cleanly withemacs-color-chain (the other SplitMix64 skill —
that one is on-demand single-apply via C-c g a; strobe-walk is continuous
auto-tick). Don't enable both at once on the same faces.
Gay-backed strobe (merged mode)
As of 2026-04-19 there is a bridge file
~/.claude/skills/emacs-strobe-walk/color-walk-gay.el that loads both
skills and rewires the strobe's two helpers (horsin/-sm, horsin/-hsl)
to delegate to gay--splitmix64 / gay--hsl-to-hex. Single source of
truth for the math; strobe provides hooks + face spec, gay provides the
color chain.
To launch a daemon with merged mode:
emacs --daemon=NAME -l ~/.claude/skills/emacs-strobe-walk/color-walk-gay.el
# or hot-load into a running daemon:
emacsclient -s NAME -e '(load-file "~/.claude/skills/emacs-strobe-walk/color-walk-gay.el")'
horsin/seed and gay-seed are mirrored at load time; horsin/reseed
is advised to also update gay-seed. Reseeding either now retargets
both the strobe trajectory and any on-demand gay-apply-chain calls.
Behavioral identity: same SplitMix64 constants, same face spec, same
output — this is deduplication, not a visual change.
Takeover recipe (one-shot)
takeover.bb in this skill dir does the whole "I'm sitting down at a
daemon, give me my workspace" routine in a single call. Loading this
skill is enough — no need to also load emacs-strobe-walk /
emacs-color-chain / tmux / org; the script pulls what it needs.
~/.claude/skills/alice-emacs-mods/takeover.bb # server + 6 orgs + 0x42D
~/.claude/skills/alice-emacs-mods/takeover.bb factory # same for factory daemon
~/.claude/skills/alice-emacs-mods/takeover.bb server 4 0xCAFE
What it does, in order:
Finds emacsclient via /nix/store/*emacs-nox-*/bin/emacsclient (with
PATH / homebrew fallbacks).
Probes the daemon using perl -e 'alarm 3; exec @ARGV' — never hangs
on a stale socket (the factory socket has bitten us; claude-crdt
and server are usually live).
Finds N most-recent .org files across ~/worlds ~/org ~/org-roam ~/.emacs.d using stat -f '%m %N' + sort -rn (macOS stat syntax).
Splits every frame of the daemon into a 2×3 grid via
split-window … 'below + 'right, then balance-windows, and
visits one file per pane in reading order:
w1 w4
w2 w5
w3 w6
Hot-loads ~/.claude/skills/emacs-strobe-walk/color-walk-gay.el and
calls (horsin/reseed SEED)with an explicit seed. Gotcha: after
the bridge loads, horsin/reseed is advised with arity 1 — calling it
no-arg raises Wrong number of arguments. The script catches that
and falls back to the no-arg form for the plain color-walk.el case.
Daemon roles (matters — don't pick the wrong one)
Daemon
What it is
Good for takeover?
server
The real frame the user attaches to with emacsclient -t -s server
yes (default)
factory
Full init.el daemon; may be stale (hung probe)
sometimes
claude-crdt
-Q headless for CRDT sharing — no visible frame by default
no (placement is invisible)
horsin-around
-Q strobe-only daemon
no
Lesson 2026-04-20: targeting claude-crdt placed 6 files on an invisible
frame while the user watched an unrelated emacs -nw splash. Always target
server unless you have a reason not to.
Attach
emacsclient -s server -t # TTY frame in current terminal
emacsclient -s server -c # new graphical frame (GUI build only — N/A here)
