··· 1 1 + --- 2 2 + name: dev-loop 3 3 + description: Run trawler with the devtools automation server to see and drive the app while developing — seed a fixture graph, launch, inject keystrokes, dump UI state, take screenshots. Use when asked to run the app, verify a change visually, screenshot the UI, or exercise a flow in the real app. 4 4 + --- 5 5 + 6 6 + Drive a real trawler instance over its devtools socket. Everything here is 7 7 + cross-platform Rust — no OS-specific automation tools. 8 8 + 9 9 + ## The loop 10 10 + 11 11 + 1. **Kill any running instance first** — a running `trawler.exe` holds a 12 12 + file lock that makes `cargo build` fail: 13 13 + 14 14 + ```sh 15 15 + # Windows: taskkill //IM trawler.exe //F (ignore "not found" errors) 16 16 + # POSIX: pkill -x trawler 17 17 + ``` 18 18 + 19 19 + 2. **Build with devtools** (release builds never include it): 20 20 + 21 21 + ```sh 22 22 + cargo build -p trawler --features devtools 23 23 + ``` 24 24 + 25 25 + 3. **Seed a scratch fixture graph** (deterministic content — same pages, 26 26 + blocks, tags, properties, and one query block every time; refuses to 27 27 + overwrite an existing graph, so remove the dir to reseed): 28 28 + 29 29 + ```sh 30 30 + ./target/debug/trawler --seed-fixtures <scratch-dir>/fixture-graph 31 31 + ``` 32 32 + 33 33 + Never point a dev session at the user's real graph 34 34 + (`%APPDATA%\trawler\graph`) — always set `TRAWLER_GRAPH_DIR`. 35 35 + 36 36 + 4. **Launch with the server enabled**, in the background: 37 37 + 38 38 + ```sh 39 39 + TRAWLER_GRAPH_DIR=<scratch-dir>/fixture-graph TRAWLER_DEVTOOLS=1 \ 40 40 + ./target/debug/trawler 41 41 + ``` 42 42 + 43 43 + The port is printed to stdout and written to 44 44 + `<graph-dir>/devtools.port`. 45 45 + 46 46 + 5. **Drive it**: connect to `127.0.0.1:<port>`, send one JSON object per 47 47 + line, read one JSON response per line (in order): 48 48 + 49 49 + ```json 50 50 + {"cmd":"keys","keys":"ctrl-k"} // keystrokes through the keymap 51 51 + {"cmd":"type","text":"trawler-design"} // text into the focused input 52 52 + {"cmd":"dump"} // structured UI state (v1) 53 53 + {"cmd":"bounds"} // window x/y/w/h/scale 54 54 + {"cmd":"screenshot","path":"C:/abs/path/shot.png"} 55 55 + ``` 56 56 + 57 57 + PowerShell client sketch: 58 58 + 59 59 + ```powershell 60 60 + $c = New-Object Net.Sockets.TcpClient("127.0.0.1", $port) 61 61 + $w = New-Object IO.StreamWriter($c.GetStream()); $w.AutoFlush = $true 62 62 + $r = New-Object IO.StreamReader($c.GetStream()) 63 63 + $w.WriteLine('{"cmd":"dump"}'); $r.ReadLine() 64 64 + ``` 65 65 + 66 66 + 6. **Look at the result**: `Read` the screenshot PNG (multimodal), or parse 67 67 + the `dump` JSON for assertions. Prefer `dump` for "is the state right", 68 68 + the screenshot for "does it look right". 69 69 + 70 70 + 7. **Clean up**: kill the instance when done (and before any rebuild). 71 71 + 72 72 + ## Facts that save time 73 73 + 74 74 + - Keystroke syntax is gpui's `Keystroke::parse`: `"ctrl-k"`, `"shift-tab"`, 75 75 + `"alt-up"`, `"enter"`, `"escape"`. Multiple in one command: 76 76 + `"ctrl-k enter"`. 77 77 + - Replies arrive after the action ran, but debounced work (query 78 78 + re-evaluation, ~400ms) settles later — poll `dump` until it does. 79 79 + - The journal view only renders journal pages. To reach fixture pages 80 80 + (`trawler-design`, `reading-list`), navigate first: 81 81 + `keys ctrl-k` → `type <page name>` → `keys enter`. Quick-open's top match 82 82 + for a partial name may be a tag, not the page — type the full page name. 83 83 + - The fixture's journal page is `2026-07-10`; the app also creates an 84 84 + empty journal page for the real today and focuses it at launch. 85 85 + - Malformed/unknown commands return `{"ok":false,...}` and are harmless. 86 86 + - Screenshot failing (`ok:false`) does not break the session — it's 87 87 + best-effort per platform (Wayland especially); `dump` always works. 88 88 + - For behavior questions, prefer the headless UI tests 89 89 + (`cargo test -p trawler`, see `crates/trawler/src/ui_tests.rs`) over 90 90 + driving the live app — they're deterministic and CI-runnable.

··· 59 59 TRAWLER_GRAPH_DIR=/tmp/my-test-graph cargo run -p trawler 60 60 ``` 61 61 62 62 + ## Dev automation (devtools) 63 63 + 64 64 + For development — especially agent-assisted development — trawler has an 65 65 + optional automation mode: headless UI tests, a deterministic fixture graph, 66 66 + and a local socket for driving and observing a running instance. None of it 67 67 + exists in a default build. 68 68 + 69 69 + ### UI tests 70 70 + 71 71 + `cargo test --workspace` includes gpui integration tests 72 72 + (`crates/trawler/src/ui_tests.rs`) that open the real `TrawlerApp` over a 73 73 + seeded fixture graph on gpui's fake test platform — no window, no GPU — and 74 74 + drive it through the real keymap with simulated keystrokes. They run 75 75 + identically on every OS and in CI. 76 76 + 77 77 + ### Fixture graphs 78 78 + 79 79 + `trawler-core`'s `fixtures` feature provides a deterministic seeded graph 80 80 + (fixed dates, fixed content, even stable block ids) shared by the UI tests 81 81 + and interactive dev sessions, so state dumps and screenshots are comparable 82 82 + across machines. Seed one from the CLI (devtools build): 83 83 + 84 84 + ```sh 85 85 + cargo run -p trawler --features devtools -- --seed-fixtures /tmp/scratch-graph 86 86 + ``` 87 87 + 88 88 + ### Automation server 89 89 + 90 90 + Build with `--features devtools` and launch with `TRAWLER_DEVTOOLS=1` (both 91 91 + required — a devtools binary run normally opens no sockets): 92 92 + 93 93 + ```sh 94 94 + TRAWLER_DEVTOOLS=1 TRAWLER_GRAPH_DIR=/tmp/scratch-graph \ 95 95 + cargo run -p trawler --features devtools 96 96 + ``` 97 97 + 98 98 + The app binds a TCP listener on `127.0.0.1` (OS-assigned port, printed to 99 99 + stdout and written to `<graph-dir>/devtools.port`) speaking one JSON object 100 100 + per line, one response per line: 101 101 + 102 102 + | Request | Effect | 103 103 + |---|---| 104 104 + | `{"cmd":"keys","keys":"ctrl-k"}` | Dispatch keystrokes through the real keymap (`Keystroke::parse` syntax, whitespace-separated). No OS focus needed. | 105 105 + | `{"cmd":"type","text":"hello [["}` | Insert text through the focused editor's input path (triggers completion, query re-eval, etc.). | 106 106 + | `{"cmd":"dump"}` | Versioned JSON of semantic UI state: view, visible rows, focused block/cursor/selection, open popups, window bounds. | 107 107 + | `{"cmd":"bounds"}` | Window position/size/scale only. | 108 108 + | `{"cmd":"screenshot","path":"shot.png"}` | Capture the app window to a PNG. | 109 109 + 110 110 + Failures answer `{"ok":false,"error":...}` and never affect the app. Replies 111 111 + are sent after the dispatched action has run; poll `dump` for state that 112 112 + settles asynchronously (e.g. query re-evaluation after its debounce). 113 113 + 114 114 + Screenshots are best-effort per platform: solid on Windows and X11, macOS 115 115 + needs a one-time Screen Recording permission, and Linux Wayland depends on 116 116 + the compositor — everything else keeps working where capture doesn't. 117 117 + (Implementation note: capture runs in a short-lived helper process because 118 118 + xcap won't enumerate the calling process's own windows on Windows.) 119 119 + 62 120 ## Graph directory format 63 121 64 122 Everything under the graph directory is derived from, or is, a single Loro

Keystroke syntax is gpui's 13 13 + //! `Keystroke::parse` (e.g. `"ctrl-k"`, `"shift-tab"`). Failures answer 14 14 + //! `{"ok":false,"error":...}` and never affect the app. 15 15 + //! 16 16 + //! Threading: a plain listener thread does blocking line I/O and forwards 17 17 + //! `(request, reply-sender)` pairs over an async channel to a single 18 18 + //! foreground task spawned on the GPUI main thread, which executes each 19 19 + //! command against the real window. Input therefore needs no OS focus and 20 20 + //! replies are sent only after the dispatched action has run. Screenshots 21 21 + //! are the exception: capture is OS-level and needs no GPUI state, so it 22 22 + //! runs on its own thread and replies when the PNG is written, keeping a 23 23 + //! slow capture from hitching the UI. 24 24 + 25 25 + use std::io::{BufRead as _, BufReader, Write as _}; 26 26 + use std::net::{TcpListener, TcpStream}; 27 27 + use std::path::{Path, PathBuf}; 28 28 + use std::sync::mpsc as sync_mpsc; 29 29 + 30 30 + use futures::channel::mpsc as async_mpsc; 31 31 + use futures::StreamExt as _; 32 32 + use gpui::{App, AsyncApp, Keystroke, Modifiers, WindowHandle}; 33 33 + use serde::{Deserialize, Serialize}; 34 34 + use serde_json::{json, Value}; 35 35 + use trawler_core::outline::Outline; 36 36 + 37 37 + use crate::{TrawlerApp, View}; 38 38 + 39 39 + /// Version stamped on every `dump` response; bump on breaking schema 40 40 + /// changes so clients can detect drift. 41 41 + const DUMP_VERSION: u64 = 1; 42 42 + 43 43 + /// Written into the graph directory so clients can discover the port. 44 44 + const PORT_FILE: &str = "devtools.port"; 45 45 + 46 46 + // Unknown fields are tolerated (serde can't deny them on an internally 47 47 + // tagged enum) — deliberate: newer clients degrade gracefully. 48 48 + #[derive(Debug, PartialEq, Deserialize)] 49 49 + #[serde(tag = "cmd", rename_all = "snake_case")] 50 50 + enum Request { 51 51 + /// Dispatch whitespace-separated keystrokes through the window keymap. 52 52 + Keys { keys: String }, 53 53 + /// Insert literal text through the focused editor's input path. 54 54 + Type { text: String }, 55 55 + /// Structured UI state (see [`Dump`]). 56 56 + Dump, 57 57 + /// Window position/size/scale only. 58 58 + Bounds, 59 59 + /// Capture the app window to a PNG at `path`. 60 60 + Screenshot { path: PathBuf }, 61 61 + } 62 62 + 63 63 + /// Devtools CLI flags that run instead of the app. Returns `true` if one 64 64 + /// was handled (successfully or not) and `main` should return immediately. 65 65 + pub fn handle_cli() -> bool { 66 66 + let args: Vec<String> = std::env::args().skip(1).collect(); 67 67 + match args.first().map(String::as_str) { 68 68 + // Seed the standard fixture graph and exit. 69 69 + Some("--seed-fixtures") => { 70 70 + match args.get(1) { 71 71 + Some(dir) => match trawler_core::fixtures::seed(dir) { 72 72 + Ok(_) => println!("seeded fixture graph at {dir}"), 73 73 + Err(err) => eprintln!("failed to seed fixture graph at {dir}: {err}"), 74 74 + }, 75 75 + None => eprintln!("usage: trawler --seed-fixtures <dir>"), 76 76 + } 77 77 + true 78 78 + } 79 79 + // Hidden helper mode used by the `screenshot` command: capture the 80 80 + // window of another trawler process.

··· 89 89 - [Keystroke injection races async work (query re-eval, journal rollover timer)] → Replies are sent after the dispatched action returns, and `dump` reads current state at time of call; clients poll `dump` for settled state rather than the server guessing quiescence. If this proves insufficient, a `settled` command that awaits pending foreground tasks is the escape hatch (open question O2). 90 90 - [`gpui 0.2.2` test-support has rough edges on the published crate vs. Zed's in-tree usage] → The smoke test in task one surfaces this immediately; worst case the harness pins what works and documents gaps rather than blocking the dev server track. 91 91 92 92 - ## Open Questions 92 92 + ## Open Questions — resolved during implementation 93 93 94 94 - - **O1 — `type` implementation detail**: whether text insertion goes through per-character `dispatch_keystroke` or the platform text-input (IME) path; decide during implementation by whichever matches what real typing exercises in `BlockEditor`. 95 95 - - **O2 — quiescence**: is "reply after dispatch + client polls `dump`" sufficient for the query-block debounce (~hundreds of ms) workflows, or do we need a `settled`/`wait-idle` command in v1? 96 96 - - **O3 — fixture scope**: exact fixture inventory (how many pages/blocks, which query examples) — small enough to eyeball in a screenshot, rich enough to exercise references, tags, properties, and a query block. Proposed starting point: one journal page (fixed date), two named pages, ~20 blocks, one query block; refine while implementing. 94 94 + - **O1 — `type` implementation** (resolved): both paths at once, for free. Each character is dispatched as an unmodified `Keystroke` with `key_char` set; `Window::dispatch_keystroke` runs keymap dispatch first and falls through to the focused editor's `EntityInputHandler` (the IME path) for unbound keys. Verified live: `type "[["` opens reference completion exactly as real typing does. 95 95 + - **O2 — quiescence** (resolved for v1): reply-after-dispatch plus client-polls-`dump` was sufficient in live verification, including quick-open navigation flows. No `settled` command in v1; it remains the escape hatch if query-debounce (~400ms) workflows ever need it. The dev-loop skill documents the polling convention. 96 96 + - **O3 — fixture inventory** (resolved): 19 blocks — journal page `2026-07-10` (6 blocks, three levels deep, `#trawler`/`#project` tags, `[[trawler-design]]`/`[[reading-list]]` refs), `trawler-design` (Goals/Tasks subtrees, `due`/`priority`/`done` typed properties, the query block `(table (tag 'project) '("due" "priority"))`), `reading-list` (two `#book` blocks with `author`/`rating` properties, one `[[2026-07-10]]` date reference). Loro peer id pinned to `1`, so block ids themselves are deterministic across machines. 97 97 + 98 98 + ## Implementation notes — deviations discovered while building 99 99 + 100 100 + - **D6 amendment — screenshot runs in a helper process.** xcap's Windows backend deliberately refuses to enumerate the calling process's own windows (a `GetWindowText`-deadlock precaution), so in-process capture can never see the app on Windows. The `screenshot` command re-executes the trawler binary as a short-lived helper (`--devtools-capture <pid> <path>`); from a child process the app window is capturable with identical code on every platform. Verified on Windows: xcap's GDI path uses `PrintWindow` with `PW_RENDERFULLCONTENT`, which captures the D3D11 swapchain correctly. 101 101 + - **D4 amendment — input dispatch must not lease the root view.** `WindowHandle<TrawlerApp>::update` holds a lease on the app entity for the closure's duration; a dispatched action that updates the app (all of them) then double-leases it and aborts the process (found in live verification, first `keys ctrl-k`). `keys`/`type` dispatch through `AnyWindowHandle::update`, which provides the window without leasing the view. `dump`/`bounds` still use the typed handle — they only read. 102 102 + - **Keystrokes only reach rendered rows.** GPUI dispatches through the focused element's context chain, and a `BlockEditor` registers its input handler during paint — so focusing a block whose row isn't rendered (e.g. a `trawler-design` block while the journal view is showing) silently drops input. UI tests and dev-server clients must navigate to the page first (quick-open: `ctrl-k` → type name → `enter`); documented in `ui_tests.rs` and the dev-loop skill. 103 103 + - **`Request` tolerates unknown JSON fields** (serde cannot `deny_unknown_fields` on an internally tagged enum) — kept deliberately as forward compatibility and pinned by a protocol test. 104 104 + - **ui-test-harness spec scenarios were relaxed to match actual app behavior**: after Enter-split, focus moves to the new sibling but the cursor sits at the *end* of its content (not the start), because `focus_block` always opens an editor with the cursor at the end; same for Backspace-merge (focus on merged block, cursor at end, not at the join point). The authoritative outline-editor spec pins neither, so the tests document current behavior rather than redefine it — flagged as a possible UX polish item, not changed in this change.
