Commits ahead of a tracked upstream are marked with `↑` and commits on the upstream but not yet here with `↓`; a branch with no upstream has neither. Each commit carries the refs that point at it — `HEAD → dev`, other local branches, tags, remote branches, in that order — in the TUI and the web viewer alike. `Enter` drills into the commit's changed files, and `Esc` returns to the commit list. History loads in pages. The first page and subsequent prefetch distance use [`[log]`](configuration.md#log) settings, and scrolling near the end requests more.

Touch-dragging a terminal scrolls it; the key bar supplies Escape, Tab, arrows, and control keys when a soft keyboard cannot. A soft keyboard opening does not resize the panes: the PTY keeps its grid and the pane shows the part of it around the cursor — the bottom of a full screen, the top of a terminal just opened — so a full-screen program is not made to repaint from the top every time the keyboard comes and goes. Layout changes made while the keyboard is up are applied once it closes. Its `Ctrl` button is a latch for the next typed character. The keyboard-bar preference is stored in the browser, so it can be changed from the terminal toolbar. The shortcut leader key is stored in the browser too, and can be rebound or switched off from the shortcut sheet. The message form (the pencil in the terminal toolbar and at the end of the key bar, or the leader followed by `m`) exists because xterm's hidden input field drops and repeats characters from an IME on iPadOS, which makes Korean typed straight into a pane unreliable; an ordinary text field composes it correctly. Send writes the message into the active pane and presses Return, so it runs at once; Cmd/Ctrl+Return does the same from the keyboard, and Return alone adds a line. When the program has turned on bracketed paste, a multi-line message goes in as one paste rather than one command per line. Clear empties the field. A draft is kept per pane for the life of the page, so closing the form does not lose it. The TUI has no such form: it reads keys from the host terminal, whose IME already composes. diff --git a/plugins/AGENTS.md b/plugins/AGENTS.md index 7a6abef0..ba986050 100644 --- a/plugins/AGENTS.md +++ b/plugins/AGENTS.md @@ -2,6 +2,8 @@ 이 문서는 `plugins/` 아래 독립적으로 빌드되는 plugin crate에 적용한다. 저장소 공통 규칙은 [루트 AGENTS.md](../AGENTS.md)를 따르고, plugin 계약의 기준은 [Plugins](../docs/plugins.md)와 [Plugin Host](../docs/architecture/plugin-host.md)다. +`nightcrow-memory`는 예외적으로 host가 실행하는 plugin이 아니라 pane 안의 provider가 띄우는 MCP helper다. 아래 host 경계 중 plugin protocol에 관한 항목은 적용되지 않지만, repository 인스턴스를 섞지 않는 것과 pane token을 인증으로 쓰지 않는 것은 똑같이 지킨다. 계약은 [Plugin Host](../docs/architecture/plugin-host.md#pane-helper-shared-memory)에 있다. + ## Host 경계 - Plugin은 host 주소 공간에 들어가는 library가 아니라 별도 실행 프로세스다. host 내부 모듈이나 Rust ABI에 의존하지 말고, stdin/stdout의 NDJSON과 명시적 protocol version으로만 통신한다. 와이어 형태를 호환되지 않게 바꾸면 양쪽 계약을 함께 갱신하고 version mismatch를 추측으로 복구하지 않는다. diff --git a/plugins/nightcrow-memory/Cargo.toml b/plugins/nightcrow-memory/Cargo.toml new file mode 100644 index 00000000..792add3d --- /dev/null +++ b/plugins/nightcrow-memory/Cargo.toml @@ -0,0 +1,22 @@ +[package] +name = "nightcrow-memory" +version.workspace = true +edition = "2024" +rust-version = "1.89" +description = "nightcrow helper: notes that the coding agents in one repository's panes share over MCP" +license = "Apache-2.0" +publish = false + +[dependencies] +# The same line-and-JSON footing as the recovery plugin: an MCP stdio server is +# newline-delimited JSON-RPC, so no SDK and no async runtime. +anyhow = "1" +serde = { version = "1", features = ["derive"] } +serde_json = "1" +# The shared store. `bundled` compiles SQLite in rather than linking the +# system's, so every platform gets the same build — with FTS5 — instead of +# whatever the OS ships.
