feat(footer): default to a one-line plain footer with a lighter layout by tt-a1i · Pull Request #26 · openpi-dev/openpi

tt-a1i · 2026-08-20T12:49:40Z

What

Switches the default dashboard footer from the one-line powerline dashboard to a one-line plain footer:

DEFAULT_FOOTER_STYLE: powerline → plain
DEFAULT_FOOTER_LINES: cwd model thinking context cache cost throughput |flex| git pr → cwd git pr |flex| model context cost

Renders as:

~/project · main · PR #42 seal/glm-5.3 · ctx 25% · $0.213

Why

The powerline default ships ANSI256 blocks + separator glyphs that depend on Nerd Font for best rendering; plain text is readable in every terminal with no font requirements.
The old default crammed 9 segments into one line; the new default keeps the highest-signal items (location, model, context, cost) and drops thinking/cache/throughput, which remain available via custom ui_footer_lines.
Powerline / powerline-mono remain first-class presets — users who want colored blocks can opt in with one command.

Notes

Existing configs are untouched: users with explicit footerStyle/footerLines in my-pi-setup.json keep their settings (verified in the legacy-migration tests).
Updated: default constants, setup prompt copy, README defaults table, and affected tests.
bun run check and bun run test (713 + 29 tests) pass.

Switch the default footer from a one-line powerline dashboard to a one-line plain footer: cwd/git/pr on the left, model/context/cost on the right. Powerline stays available as an explicit preset for users who want colored blocks. - DEFAULT_FOOTER_STYLE: powerline -> plain - DEFAULT_FOOTER_LINES: cwd model thinking context cache cost throughput flex git pr -> cwd git pr flex model context cost - Update setup prompt, README defaults table, and tests

The leaner default layout from #26 leaves room for a single status to inline at width 80, so the old lines.length >= 2 assertion encoded placement rather than the property it meant to protect: the status must stay visible.

* fix(plan-mode): always offer an exit from plan mode * feat(footer): inline a single status into the first footer line when it fits * feat(plan-mode): judge bash by command effect instead of syntax Allow quoted literal arguments and a narrow set of read-only search and inspection tools.\nKeep shell expansion, composition, unsafe flags, and unknown effects fail-closed so plan mode cannot mutate before approval. * refactor(plan-mode): fold short-flag clusters into one scanner The first pass added cluster handling twice: once inside scanArguments and once in a separate scanShortFlagClusters pass. The scanArguments branch was not gated by program, so it silently widened git and gh too. Collapse both into one opt-in parameter that only the file-inspection programs pass. * test(footer): assert status visibility rather than a dedicated line The leaner default layout from #26 leaves room for a single status to inline at width 80, so the old lines.length >= 2 assertion encoded placement rather than the property it meant to protect: the status must stay visible. --------- Co-authored-by: tt-a1i <tt-a1i@users.noreply.github.com>
