2026-10-26importance: mark an agent high, normal, or lowIgor Soarez
within a status, more important agents are listed first, and so jumped to first; status stays first. a high agent shows a bold ! before its name, a low agent's name is lightly dimmed with "low" on its second line, and it makes no sound (it still notifies and waits in line). in pi, /importance high|normal|low (completes the levels; none once one is typed out, so Enter runs it). the extension saves it in the session as a custom entry (dingger-importance), so /reload, restarts, /resume and restore bring it back; /new starts at normal. it shows a level other than normal in pi's footer, emits dingger:importance { level } for other extensions, and sends it with every report. for other agents, `dingger importance [level] [--pane]`; it refuses a pi that reports itself, whose saved level would win. the daemon stays the one writer of pane state: it writes @dingger_importance (unset for normal), which goes with the agent and survives a daemon restart. `dingger status` marks high and low. tests: e2e step 21 (order, the option, no sound for low, the menu bar, the command, the extension through a harness that now matches pi's extension API), a DINGGER_SOUND seam so sounds are observable, and a status-line check that read the counts once (flaky) now polls. pi-live: /importance in real pi 1.4, its footer and session entry, and the level after a restore; every pi there now uses the test's agent directory (a restored pi read the user's). negative controls fail each part.
2026-10-25terminal commands are silent when tmux runs themIgor Soarez
tmux shows a hook's output and a non-zero exit in view mode over the pane. the focus hook's normal outcomes (focus moved on, Ghostty not in front) exited 1, and the one-second settling made "focus moved on" common: "'dingger terminal focused --client ...' returned 1" kept covering panes. `dingger terminal focused` and `terminal raise` now always exit 0 and print nothing unless run by hand. tmux::client_format checks that tmux answered for the client asked about: for a client that is gone, tmux answers for the current one, so a raise for a client that had just detached raised another client's terminal. e2e step 20: no pane in view mode after the hook's failures, a gone client raises nothing, and a focus held past the settling second; the old code fails the new checks.
2026-10-23raise the terminal window that holds the tmux clientIgor Soarez
a jump (any click, a shortcut, search) activated the terminal app, which raised whichever window was used last. now: - the client: the named one (a status-line click), else one already on a session holding the agent's window (several terminal windows can show one session; it shows the agent without switching, and keeps its own session in a session group), else any; the focused one first, then the one used last (its last input or focus). - Ghostty (1.3+, scriptable by terminal id, not by tty): dingger learns which terminal holds each client when it gains focus. tmux's client-focus-in hook runs `dingger terminal focused`, which asks Ghostty for its focused terminal and records it in @dingger_terminal_<tty>, but only if the client is still focused once Ghostty answered (a fast switch must not pair the wrong terminal); a terminal holds one client, so an older pairing with it is dropped. `focus` raises the exact terminal (window, tab, split) through `tmux run-shell`: Apple Events from the tmux server count as Ghostty's own, so no permission prompt. a terminal that is gone is forgotten and the app activated, as without a pairing. - in a hook, #{client_name} can be another client (the previous event's); the snippet's hook uses #{hook_client}. e2e step 20: two nested clients on one session, focused by typing focus reports into their outer panes, a fake osascript as Ghostty, a fake open (tests never activate a real app); it loads the snippet's own hook line. each rule has a negative control that fails.
2026-10-23session groups: list each pane once, save each group onceIgor Soarez
a pane in several sessions (a session group, `new-session -t`, or a linked window) was listed once per session: every agent of a group showed twice in the menu, panel, search, `dingger status`, and the counts. and snapshots saved each session of a group with its own copy of the windows, so restore would have rebuilt them twice and resumed each agent twice on one session file. - a pane keeps its first listing (tmux lists sessions by name) and is attended if the user looks at it through any session of the group. - snapshots keep the first session of each group; the others are not restored. e2e step 19 covers both; the previous binaries fail it. two checks (step 11's and this one) waited for idle after a turn that started from idle, which passed before the turn was even processed: they now wait for working first, and the negative control for group attendance fails as it should. step 18 now waits for the snapshot it later restores from.
2026-10-23write a pane's options in one tmux command listIgor Soarez
the watcher wrote @agent_state, then @dingger_hook, as separate tmux calls. a daemon stopped between them left a done display state next to a stale "working" hook state, which the restarted daemon trusted: the agent came back as working. now every changed option of a pane is one command list, which tmux applies as a unit (and one process instead of several). tests/kill-race.sh kills the daemon the instant an agent shows done: 24 of 40 kills left the options inconsistent before, 0 of 40 now. e2e step 17 runs it 20 times; the previous binary fails it.
2026-10-23restore, step 2: resume agents, retype command linesIgor Soarez
- the pi extension reports its session file; the daemon keeps it in the pane option @agent_session, and snapshots carry it. restore runs `pi --session <file>` in the rebuilt pane, one agent every 0.5s, then reports which agents run and which were interrupted mid-turn. - other panes: the command line running in them is typed at the new prompt but not run. exactly as typed with the zsh hook (dingger install zsh: preexec/precmd keep @dingger_cmd), else the foreground program's exact argv from the kernel (KERN_PROCARGS2), shell-quoted. - "at a prompt" is the pane's own shell owning the terminal's foreground process group, not a name check: `sh -c ...` is a running program. - an agent or command that exits keeps its place in snapshots for 60s, so a shutdown that stops programs before tmux still restores them. - typing waits for each new prompt (text typed earlier echoes twice). e2e step 16 covers resume with a session path containing a space, the interrupted report, an agent that exits just before the server dies, a quoted command retyped not run, and the hook's text; dropping the grace period, judging prompts by name, running retyped commands, or not storing the session reference each fail it. the test's fake pi is guarded so a real pi never starts.
2026-10-23restore, step 1: layout snapshots and dingger restoreIgor Soarez
the daemon saves the tmux layout when it changes: sessions, windows (index, name, automatic-rename, layout, size, zoom, active), and panes (directory, active, agent). a new history file for layout changes, a rewrite for details, the last 50 kept, nothing saved while tmux is down. when a different server runs (or none), the old server's last snapshot is pinned as the restore candidate before the new server's snapshots start. dingger restore rebuilds missing sessions by tmux id: panes split from the newest so they keep their order, the saved layout applied at the saved size, then the size released so windows follow clients again. a bare session of the same name (a terminal's `new-session -As 0`) is replaced, its clients switched over first; used sessions are kept. --dry-run, --list, --from, --session. e2e step 16 kills a server with a client attached like ghostty's, restarts it, restores, and compares every window and pane; splitting the wrong pane, not replacing bare sessions, not pinning, or keeping the saved size each fail it. e2e keeps its state in its temp dir.
2026-10-20fix clicks from the menu bar app: find tmux without homebrew on PATHIgor Soarez
launchd starts the menu bar app with PATH=/usr/bin:/bin:/usr/sbin:/sbin, so the `dingger focus` it runs for every click (panel rows, menu rows, the jump shortcut) could not find homebrew's tmux and failed with a misleading "no tmux client attached"; the app discarded the error. dingger now finds tmux on PATH or in the usual install locations (DINGGER_TMUX overrides), reports a missing tmux as such, and the app logs failed jumps. also: panel rows own every click inside them (labels took the clicks and counted as window-drag background). e2e step 14 repeats the menu bar row click and dingger focus under launchd's environment; both fail with the previous binaries.
2026-10-20menu rows lead with the agent's session name; harness and place move belowIgor Soarez
herdr's sidebar shows the session name in place of the harness label (via the user's herdr-session-name extension). dingger reads it from the title pi already sets ("π - <name> - <dir>"); other agents use herdr's terminal_title_stripped rule, and claude's default "Claude Code" title or tmux's host-name title count as no name. the daemon stores it as @agent_name for every surface. menu rows: colored status symbol + name as the title (the harness, dimmed, only when unnamed), and a native subtitle "session · window · harness", plus how long done/blocked agents have been waiting; one separator between agents waiting for you and the rest. dingger status shows the same.
2026-10-20rebuild the status model as herdr's state machine, event-driven and testedIgor Soarez
the seen logic was inverted: first observations were marked done and real completions idle, so the menu showed teal for agents that did nothing and green for agents that finished, and attending changed nothing visible. - watcher::advance is herdr's apply_pane_state_change + mark_active_tab_seen as a pure function, unit-tested against herdr's own cases; attendance is window-level like herdr's active tab - hook reports are events applied in order, so a turn shorter than a poll is still a completion - event-driven: hook reports, dingger focus, and tmux focus hooks wake the watcher; notifications are delivered off-thread (the macos call blocked ticks for 2+ seconds) after the pane options are written - all per-pane state persists in tmux pane options, so restarts and deploys lose nothing, including the authoritative hook state - every click goes through dingger focus: the menu bar shells out to it and the status-line binding runs it; it picks the right client, skips the window already shown, and activates the terminal app hosting the client - the ready queue is ordered like the menu (blocked first, then oldest done) - menu bar and tmux segment render herdr's symbols in herdr's palette - tests/e2e.sh: 60 assertions against an isolated tmux server with a real client, a 30s poll interval, and a slow fake notifier
2026-10-20adopt herdr's five-status model with symbols style and focus detectionIgor Soarez
statuses are now herdr's verbatim: working (yellow), blocked (red), done (teal, finished and unattended), idle (green, attended since its last transition), unknown (gray) - priority blocked > done > working > idle > unknown. the daemon watches tmux focus (pane_active of attached clients) to mark panes attended, which is what separates done from idle. menu bar renders symbols-style glyphs with herdr's colors in priority order; the tmux segment stays after the clock and renders done/blocked/ working counts from numeric options. deployment note: do not strip the binary - it invalidates the ad-hoc signature and macOS kills it on launch.
2026-10-19ready-queue fifo with click-to-focus; redesign presentation per design panelIgor Soarez
daemon tracks when each agent became ready (idle/blocked, unacked) and publishes fifo queue + numeric counts as server-global options; unknown to idle transitions stay out of the queue (restart spam). new dingger focus subcommand jumps to the longest-waiting pane and acks it, bound to status-right clicks in tmux. menu bar redesigned per two-model design panel: monochrome sf-symbol bell + queue depth, queue-ordered rows with state glyphs and right-aligned targets, row clicks ack like focus does. tmux segment renders glyph+count with a single red accent for blocked; fixes unescaped comma in the conditional format that truncated the segment entirely.
2026-10-19menu bar app: live agent states from tmux pane optionsIgor Soarez
single-file appkit status item (menubar/main.swift, LSUIElement) polling @agent/@agent_state pane options every 2s: counts in the bar, per-pane rows with click-to-focus via switch-client. daemon now also writes an @agent label per pane so the menu bar and tmux status-right can render agent names without duplicating identification logic.
2026-10-19wait for tmux at startup, force utf-8 for tmux clients, add launchd packagingIgor Soarez
running under launchd, the tmux client defaults to the c locale, which makes tmux mangle tab-separated -f output into underscores, so every pane parsed as one field and the watcher silently saw nothing; invoke tmux with -u so format output is locale-independent. drop the startup fail-fast: the watcher now waits for a tmux server and attaches when one appears, which is the right shape for a login agent. ship the launchd plist under packaging/launchd.
2026-10-19initial dingger: tmux agent watcher with herdr's detection engineIgor Soarez
extract detect-core from herdr's src/detect (engine + 22 manifests, tests unchanged) and add the dingger binary: tmux capture-pane watcher, process-tree agent identification, herdr's notification policy, embedded notification sounds, @agent_state write-back, and catalog-based manifest refresh. viewer screens are non-observations per the engine contract; reviewed by a three-model panel (opus 5.5, gpt 6.1 sol, kimi k3) with all confirmed findings applied as deletions.
