`u` moves the pin of the selection to the tip of its ref when the pin is only behind it: a switch to that branch with exactly the tip the row shows, nothing fetched; if the ref moved meanwhile, nothing happens. On the superproject it fast-forwards the branch to its upstream and restores the submodules (git pull --ff-only from the last fetch). Switch now fast-forwards a local branch that is only behind the chosen remote branch, unless another worktree has it checked out, and keeps a checked-out branch that tracks it under another name. A branch with commits of its own is still never moved. Stage pin is dropped: switching to the branch already stages it. The detail pane's palette wraps instead of cutting off keys. Add D29 and F59.

# 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.

## Install
|
|
|
|
```sh
|
|
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](architecture.md#distribution)).
|
|
|
|
## 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, `b` switches its
|
|
branch and `u` updates a pin that is behind ([actions.md](actions.md)).
|
|
|
|
Next steps, roughly in order:
|
|
|
|
1. (done) Write actions: restore, switch branch, update pin, see
|
|
[actions.md](actions.md). Stage pin was dropped (D29).
|
|
2. (done) "Problems only" (`!`) view, reusing the tree's filter.
