simonfrankenandClaude Sonnet 5.5 4ac29c04d0 Offer "quit and update" in the footer, check for updates on every start
The update check ran at most once a day and only printed a line after the
TUI exited. Now the registry is asked on every start (in the background,
3 s timeout, no cache) and the result reaches the TUI as a message.

With a newer release, the footer shows `q quit and update to vX` right of
help and quit, on a highlighted background (Theme.Highlight). `q` quits
and `main` installs the release once the terminal is restored, sharing
the code of `submarine update`; plain quit moves to `Q`, ctrl+c never
updates.

Drop LatestCached and CheckInterval. Add D27 and F58.

submarine — documentation

submarine is a terminal UI for git repositories with many (recursively nested) submodules. It shows the submodules, as a collapsible tree (plus the state of the superproject itself in the header), and describes each pin as a branch plus distance (origin/main ↓1) instead of a bare commit hash.

Documents

Document Contents
requirements.md What the tool must do: functional and non-functional requirements
state-model.md How a submodule's state is determined, summarized into issues, and how pins are resolved to refs
ux-guide.md Layout, attention hierarchy, colors, wording, navigation and key bindings
architecture.md Package layout, the provider boundary, async loading, testing
actions.md the write actions restore and switch branch (done) and stage pin (draft)
decisions.md Decision log with rationale (ADR style)

Install

curl -fsSL https://git.simon-franken.de/simonfranken/submarine/raw/branch/main/install.sh | sh

Installs submarine and the alias sub (linux/macOS, amd64/arm64) to ~/.local/bin. Update with submarine update. Maintainers publish with GITEA_TOKEN=… make release (see architecture).

Status

Prototype. The UI is complete for browsing. It reads real repositories through a git provider (internal/submodule/git): submarine [dir]. It fetches only when asked (f) and follows changes made in other shells. submarine --mock shows the built-in mock data (internal/submodule/mock). ! shows only submodules with problems. x restores the selection and b switches its branch (actions.md); stage pin is drafted there.

Next steps, roughly in order:

  1. Stage pin, see actions.md. (Restore and switch branch are done.)
  2. (done) "Problems only" (!) view, reusing the tree's filter.
