Agent 'Close' (agent-close) sent a single SIGTERM via Session.Kill and
never escalated, so an agent that traps/ignores SIGTERM (e.g. opencode)
stayed in the running tab bar until the user closed it again. Add
Session.Terminate, which reuses terminateAndWait (SIGTERM, wait, then
SIGKILL) but preserves the session entry so the exited pane stays
readable, and route handleChildClose's agent path through it in a
goroutine to keep the UI responsive during the stop timeout.
Resolves the opencode double-close TODO item.
Focused-section rows are now bare verbs (Rename, Close, Stop, Restart,
Delete, Edit) instead of repeating the focused name. The title bar
already carries the subject, and the row hint preserves fuzzy-search
matches like "close codex". Section banners are replaced by a single
blank spacer row so the verbs themselves carry the visual weight,
and the Open section no longer lists "Switch to <current>" for the
pane that's already focused.
Replaces the single-slot status-line flash with a top-right toast
stack over the focused pane. flashError, flashTransient, and
notifyAttention all push onto the same stack (cap 5, FIFO drop).
Ctrl-N dismisses the most recent toast; empty stack falls through to
the focused PTY so readline / nano / emacs / opencode bindings keep
working. A new "Clear notifications" palette item empties the stack.
Six-phase sweep: section headers (Focused / Open / Spawn / Quit) with
header-skip cursor; chip strip mirroring sw/sp/k macros, driven by
Tab; unified Spawn verbs across agent / process / terminal / custom;
dropped duplicate global Close list in favor of Ctrl-X inline close
on a Switch row plus the [Close] chip; scored matching (prefix >
word-boundary > substring > fuzzy) with matched-char highlighting;
title bar surfaces focus subject; rename forms split long subject
onto its own row; new Alt-1..9 quick-pick, Home/End, ? help overlay,
and Ctrl-R relaunch toggle inside the spawn-process form. Scroll
indicator and cursor/total counter round out the footer.
- Palette's per-child "Kill <name>" action is now labelled "Close <name>"
(action kind unchanged; still SIGTERM). Matches the existing "Close
agent: …" context entry and reads less violent for a graceful term.
- New "New Terminal" palette entry spawns a bare interactive $SHELL pane
via LaunchTerminal (kind=terminal). Replaces the default "shell"
process preset that was seeded on first run.
- Exited KindTerminal entries are now dropped from the session in
reapChild — terminals have no restart path, so leaving them behind as
greyed rows in the Processes sidebar was just clutter. processList
also filters defensively.
When opened with Ctrl-K, the palette now prepends entries for whatever
is currently focused:
- Focused scratchpad: Delete / Rename (inline form) / Edit (fire-and-
forget zed launch with stdio detached so the TUI is not suspended).
- Focused agent: Rename (inline form) / Close.
- Focused process: Rename / Delete (drops the entry; SIGKILL if alive)
/ Stop (SIGTERM, keep entry) / Restart (same argv).
The rename UX is a single-field inline form that mirrors the existing
spawn-process form, so the modal-input contract is unchanged.
scratchpad.Store grows Delete / Rename / Path so the palette can act
on a pad file by name. focusedPad is plumbed onto uiState ahead of the
scratchpad-focus UI work; until that lands it stays empty and the
scratchpad-context entries simply never surface.
Tested with palette_context_test.go and a new rename_process_via_palette
harness scenario.
Bundles the in-flight work into the first tagged release. See
CHANGELOG.md `[0.0.1] - 2026-05-14` for the full per-change list.
Highlights:
- Sidebar / chrome stability: clamp absolute cursor positioning and
printable bytes to the viewport so long-running TUIs (claude, codex)
can't spray into the right rail; bound tab bar's row clear to the
viewport width so the rail isn't wiped on every tab redraw; flag
scroll escapes (RI/IND/NEL/SU/SD/IL/DL) and clamp `CSI 0/1/2 J`/`K`
to viewport columns.
- Palette: "Spawn process…" form, macros (`sw `, `k `, `sp `), kill
entries mark the focused tab, dead agents drop out of the switch
list.
- Sidebar: split into Processes (session-wide) + Agent Tree
(per-active-agent) sections; relaunch indicator; Ctrl+W/S walks the
combined list, Ctrl+A/D steps tabs.
- MCP: protocol handshake (`initialize`, `tools/list`, `tools/call`,
`ping`), `mcp_injection.kind = cli_override / config_env` so codex
and opencode pick up the server with no file writes, `lifecycle`
help topic and tool-description cleanup-duty pointers.
- Lifecycle: orchestrator-spawned children cascade-killed when the
parent dies; orchestrator-injected prompts end with CR + delayed
Enter so claude submits cleanly.
This batches the in-flight [Unreleased] block from CHANGELOG.md into a
single commit. Highlights:
- Real MCP protocol layer (initialize / tools/list / tools/call) so
vendor MCP clients can complete the handshake against the per-PID
socket. Legacy direct-dispatch preserved for the harness.
- New mcp_injection kinds — cli_override for codex, config_env for
opencode — joining the existing env-var and config_file paths so
patterm can slot into more agents without touching their real
config or auth.
- Ctrl+A/D and Ctrl+W/S focus navigation across tabs and intra-tab
process lists, recognised in legacy / kitty CSI u / xterm
modifyOtherKeys encodings.
- Palette macros (sw / k / sp ) and reordering so open sessions
surface above spawn-new entries.
- Two-row tab bar, sidebar/tabbar/status chrome cache, viewport-wipe
on agent spawn, CR-terminated orchestrator injections, and split-
Enter PTY writes so paste-detecting TUIs see Enter as a key event.
Also fixes the bug logged in TODO: claude's Ctrl+O tool-call expansion
emits CSI 0 J, which the viewport renderer was forwarding verbatim —
wiping the sidebar to the right of the cursor and leaving the chrome
cache convinced nothing had changed. CSI 0 J and CSI 1 J are now
translated into per-row ECH sequences clamped to the viewport, same
as CSI 2 J and CSI K already were.
Agent guides (CLAUDE.md / AGENTS.md) now spell out the
TODO->CHANGELOG workflow so completed items land in the changelog
rather than as ticked entries left behind in TODO.
Module renamed github.com/harrybrwn/patterm → github.com/hjbdev/patterm
across imports.
Chrome:
- Palette redrawn with rounded box-drawing borders, accent left-bar
for the selected item, dim hints, and a separator-aware footer.
- Tab bar grew from 1 row to 3: labels with breathing room, a dim
argv subtitle truncated to each tab's width, and an accent thick
underline for the focused tab with a faint divider extending across
the rest of the host width. Layout, viewport-renderer, and screen-
renderer tests updated for the new mainTop.
- Sidebar reuses the same palette: accent section headers, `▎`
selection marker, `●`/`○` status glyphs, dim previews.
- Shared SGR constants moved into internal/app/style.go.
Palette input:
- Adjacent duplicate arrow events (legacy `\x1b[B` + kitty
`\x1b[57353u` for one keypress, or two of the same form) are now
collapsed via peekArrowEvent + chunk-level dedupe in processStdin.
- On open, push `\x1b[>0u` onto the host's kitty keyboard stack so
palette input is in plain legacy mode regardless of what the child
pushed (codex/ratatui pushes its own flags which had been leaking
to the host). Popped on close.
Tab-switch repaint (repaintFocused):
- Use the emulator's SerializeVT bytes (with SGR / cursor / DECSTBM
/ tabstops) instead of plain text, fed through the per-focused
viewport renderer so the shifter translates row positions.
- Prelude resets host SGR / DECOM / DECSTBM (pinned to viewport) /
cursor visibility before the replay, so leftover modes from the
previously-focused child don't distort the new snapshot.
- Re-emit the saved cursor as a child-space CUP after the
serialized bytes so the host cursor lands at the emulator's
actual position (overriding DECSTBM's home side-effect and the
tabstop-setup CHA sequences) AND the renderer's vr.row/vr.col
get re-synced via trackCSI.
- cursorShifter now carries childRows and rewrites empty
`\x1b[r` to `\x1b[<mainTop>;<mainBottom>r` (host coords) — the
default (1,1) shifted to (4,4) was producing a one-row scrolling
region that scroll-exploded the replay.
- After the snapshot lands, nudge the focused child with a one-row
PTY winsize toggle so the kernel emits SIGWINCH and ratatui-style
TUIs throw away their diff state and emit a fresh frame.
Codex still renders incorrectly after a focus switch; see TODO.md
"Switch-back render divergence" for the deep investigation handoff.
Codex (and other ratatui-based children) pushes kitty keyboard flags
onto the host terminal, so Ctrl-K arrives as `\x1b[107;5u` instead of
0x0B and the palette open never fired. With "report event types" also
on, the release event `\x1b[107;5:3u` followed the press and tripped
the palette's "unknown ESC sequence → cancel" branch, making the
palette flash and close.
Add a small CSI scanner / kitty CSI u decoder and use them in two
places: matchCtrlK now accepts the legacy byte, the kitty CSI u form,
and xterm modifyOtherKeys; the palette's input handler consumes whole
CSI sequences, ignores non-press events, and decodes Enter/Esc/
Backspace/arrows/Ctrl-U-N-P in their kitty forms. Ctrl-K Ctrl-K
forwards the raw matched bytes so nested TUIs that asked for kitty
input still receive kitty input.
