# lazymail

A TUI for the git mailing list.

## Status

Early scaffold: a Lazygit-style TUI over in-memory mock data, with a real
on-disk file picker for patch attachments.

- **Browse** — three panes: threads, messages, preview.
- **Participants** — filter threads and messages by participant (`f`), or
  narrow to the selected thread's author with one key (`F`).
- **Preview** — shows the message body with any inline diff hidden; press `p`
  to open the patch in a wide overlay.
- **Live** — threads and messages auto-refresh on a 2s tick while live (`t`).
- **Sender** — a separate screen for composing and sending a patch series
  (`s`), with a yazi-like file picker rooted at `$HOME`.
- **Help** — `?` separates global keybinds from context-local ones.

The real backend will fetch each list's public-inbox archive (e.g.
[`lore.kernel.org/git`](https://lore.kernel.org/git/)) or shell out to
`b4`/`lei`. Sending is not implemented yet.
