Glamorous OMP-backed chat. aichat-shaped CLI, createAgentSession engine, Julia-set wait animation, fractal coloring on the live line, glow when the turn settles, chips you can type or click.

Was briefly named chatoy. Also considered: afterglow, gumball.

Why not aichat / omp -p

aichat talks to OpenRouter. fractalglow reuses ~/.omp/agent auth (romp luna/o by default). omp -p is a 192MB coding agent; stripped createAgentSession one-shots are ~1s.

Charm's Go libraries are not imported. Glow is the markdown binary. Spring physics is a tiny Harmonica equivalent in src/spring.ts. The fractal is a rotating Julia set (src/fractal.ts) rendered with truecolor half-blocks.

Install

Runtime is Bun (>=1.3.14). Markdown uses the glow binary.

npm i -g @ramarivera/fractalglow
# or
mise use -g bun
mise use -g npm:@ramarivera/fractalglow

That puts a fractalglow command on PATH. mise's npm backend shims the package bin; first installs of a new package may need:

[tools]
"npm:@ramarivera/fractalglow" = { version = "0.1.1", allow_low_downloads = true }

From this repo, without publishing:

npm i -g .
# or: bun link

Trusted publishing

Published on npm. Later versions go through GitHub Actions: bump package.json, tag vX.Y.Z, push the tag.

On npm, add a GitHub Actions trusted publisher:

Owner/repo: ramarivera/fractalglow
Workflow filename: publish.yml
No environment

Do not add NPM_TOKEN. .github/workflows/publish.yml uses OIDC (id-token: write) and --provenance, and skips if that version already exists.

Setup

mise install
bun install
mise run test

mise run start -- "Reply with exactly the word pong"
bun run src/main.ts --demo-fractal
bun run src/main.ts -m omp-gateway/openai-codex/gpt-5.6-luna --thinking low "hello"

luna/o needs OMP_AUTH_GATEWAY_TOKEN (see .env.example). Direct Codex models use OMP AuthStorage only.

After a turn, chips accept 1 retry, 2 shorter, q quit, or a mouse click on the same labels. -s demo writes ~/.local/share/fractalglow/sessions/demo.jsonl and reloads it on the next call.

Bare TTY fractalglow is a REPL: .file, .undo, .copy, .set, tab complete, ::: multiline, Ctrl+R history search.

-e generates a command, prints $ cmd, then y run / r revise / n skip. --dry-run and -e -c print only. Non-TTY never spawns.

--style/--theme is a glow style name or JSON path. Default fractalglow is styles/fractalglow.json. Roles live in ~/.config/fractalglow/roles/<name>.md.
