✨ feat(cli): colored startup banner from the whale logo#440
Merged
Conversation
- 🎨 render the master logo (drydock.png) as a truecolor half-block banner on an interactive terminal, followed by a `drydock v<version> · <mode>` identity line - 🔧 art is baked at build time by scripts/gen-banner.mjs (deterministic), so startup decodes no image — app/banner/art.ts is generated - 🔒 written to stderr; auto-suppressed when not a TTY or NO_COLOR is set, keeping logs and piped output clean - ✅ 100% coverage: app/banner/index.test.ts (11 cases) plus entrypoint assertions that renderBanner runs for both controller and agent modes

Clean TTY-gated banner. Art baked at build time so startup pulls in no image decoder, and it's suppressed for non-TTY/NO_COLOR so logs and pipes stay clean. Coverage is full. LGTM.

Generator is deterministic, both controller/agent modes are exercised, and the gate is green. Nice touch. Approving.

What
drydock now renders a compact colored banner of the whale logo on startup when attached to an interactive terminal, followed by a
drydock v<version> · <mode>identity line.How
scripts/gen-banner.mjssamples the master logo (drydock.png) to a 50-cell-wide grid and renders each terminal row as two pixel rows via the▀half-block (upper pixel = foreground, lower = background) using 24-bit truecolor escapes. Transparent cells become spaces; blank top/bottom rows are trimmed. The result is baked intoapp/banner/art.tsso startup decodes no image and pulls in no image library. The generator is deterministic — re-running produces no diff.renderBanner({ mode })writes the art + identity line to stderr, centering it when the terminal is wider than the banner.NO_COLORis set (non-empty), so piped output, log capture, and CI stay clean. Called from the entrypoint for both controller and agent modes.Tests
app/banner/index.test.ts— 11 cases covering TTY gating,NO_COLOR(set / empty / unset), centering vs no-padding vs undefined columns, the stderr/env fallbacks, and identity-line content for both modes.app/index.test.ts— assertsrenderBannerruns with{ mode: 'controller' }and{ mode: 'agent' }.Builds on the new master logo landed in #439.
