Preserve palette index through CellBuffer so re-emitters can keep the
outer terminals theme
Part 2 of the palette-preservation work — first half was on
PtyHandle.readCells (commit 6248390). That change landed fgIndex /
bgIndex on the PtyCell shape but pty-layout tracing showed the round
trip broke inside the CellBuffer pipeline: setCell -> Cell (in
types.ts) had no index fields, so writeAnsi / diff / fullRender
silently dropped the index and re-emitted as truecolor.
Now the buffer-side Cell carries fgIndex / bgIndex (required,
number | null) and the pipeline plumbs them through:
- writeAnsi captures the index on SGR 30-37 / 90-97 / 38;5;N /
48;5;N, and clears it on 38;2 / 48;2 truecolor and on SGR 0 / 39 /
49 resets.
- cellsEqual compares the index so diff re-emits correctly when only
the index changed (same flattened RGB, different palette slot).
- diff + fullRender use shared emitFg / emitBg helpers that prefer
indexed SGR when fgIndex is non-null (SGR 30-37 for 0-7, 90-97 for
8-15, 38;5;N for 16-255) and fall back to truecolor SGR 38;2 /
48;2 otherwise.
- ptyView rendering path forwards cell.fgIndex / bgIndex from the
upstream PtyCell, so embedded panes re-emitted by consumers like
pty-layout keep the outer terminal's theme for indexed cells while
still supporting truecolor for programs that emit it.
Required rather than optional on Cell — nothing outside this repo
constructs Cell objects in our tree, and strict typing keeps the few
internal construction sites (emptyCell, makeCell, writeAnsi, FPS
counter literal in app.ts) honest. pty-layout's one selection-
highlight construction site will need a trivial fgIndex/bgIndex: null
addition.
Document the on-disk layout under docs/disk-layout.md
For non-Node consumers that want to read pty's session state directly
without paying Node CLI startup. Covers PTY_SESSION_DIR, the file
table with stability tiers (tier 1 = <name>.json, .events.jsonl;
tier 2 = .sock, .pid, .lock, theme, supervisor/), the SessionMetadata
TS shape, the events JSONL envelope and every concrete event type,
and the <target>.tmp.<pid>.<rand> atomic-write convention with an
explicit "third-party readers MUST ignore these" note.
Pre-1.0 banner: schema may change in any release; pin to a pty
version. CHANGELOG carries a "### Storage format" heading whenever
a tier-1 file shape changes.
Drift guard: tests/disk-layout-docs.test.ts asserts every
SessionMetadata field name, every concrete event-type literal, and
every file extension we write under PTY_SESSION_DIR appears in the
doc. SessionMetadata and EventBase carry "PUBLIC FORMAT" comment
markers pointing at the doc + the smoke test.
README's Events section gains a one-paragraph pointer to the doc and
mentions git-style command forwarding (pty <subcommand> ->
pty-<subcommand> on $PATH) as the recommended path for native
fast-path readers.
feat(name): decouple on-disk identifier from display label (#45)
* feat(name): decouple on-disk identifier from display label
Sessions now have a short random on-disk identifier (sock + json filename)
that is independent of the user-visible display label. This unblocks long
descriptive labels — both via `pty.toml` prefixes and via `pty run --name`
— which previously hit the macOS `sockaddr_un.sun_path` 104-byte limit.
Breaking changes
- `pty run --name <X>` now sets the displayName (any length, any printable
chars). The on-disk id is set by `--id <X>`. Both omitted → random short
id + auto-generated displayName. Both can be combined.
- `pty up` (pty.toml) gives every session a random short on-disk id. The
toml-derived `<prefix>-<sessionKey>` becomes the displayName, not the
filename. `pty up` re-run detection now matches by `(ptyfile,
ptyfile.session)` tag pair instead of by name.
- `pty.toml` gains two optional per-session fields: `id = "..."` to pin the
on-disk id and `display_name = "..."` to override the default label.
- `pty rename` validation: displayName uses the new permissive
`validateDisplayName` (≤ 500 chars, no slashes / null / newlines /
control bytes) instead of the strict `validateName` (sock-filename
charset, sock-path length). Strict validation is reserved for ids.
- `SessionMetadata.displayName` is now preserved through exit (previously
`saveExitMetadata` dropped it).
- `PtySessionDef.name` replaced by `displayName` + optional `id`;
`shortName` unchanged. External callers (`pty kill`, `peek`, `send`,
`attach`) are unaffected — they already resolved by either field via
`resolveRef`.
- `spawnDaemon`'s bundled-context fallback now passes `--id` (instead of
`--name`) to the CLI delegation path and explicitly threads
`displayName` / `--no-display-name`.
Tests
- New `tests/up-name-decouple.test.ts` covers random id, long-prefix
support, `(ptyfile, ptyfile.session)` re-run lookup, pty.toml `id` and
`display_name` overrides, and operations resolving by displayName.
- Existing tests migrated from `--name <id>` to `--id <id>` for tests
whose intent was pinning the on-disk identifier. `display-name.test.ts`
rewritten to test the new `--id` / `--name` semantics including
long-label, kernel-limit rejection, and id/name collision rejection.
Full suite green (1168 passed / 22 skipped / 1190 total).
* fix(cli): drop validateName from session-resolution paths
Long displayNames could be created via `pty run --name <long>` but
operating on them (`pty peek|send|kill|tag|events|attach|restart|rm`)
failed with the `validateName` sock-path kernel-limit error — the
strict validator was running on the user-supplied ref BEFORE
resolveRef did the lookup. The strict validator's job is to gate
on-disk id creation, not session-reference resolution.
Fix per schickling-assistant's PR #45 review:
- Drop the validateName(ref) block from 7 sites in cli.ts: attach,
peek, send, events, tag, kill, rm, cmdRestart, and tag-multi by-name
selector.
- Add resolveRef at the supervisor forget/reset dispatch sites so
cmdSupervisorForget/Reset receive a resolved name (their bodies
drop their own redundant validateName as a consequence).
- Drop the redundant validateName inside cmdRestart — its dispatcher
already resolved the ref.
validateName remains in place where it belongs: on-disk id creation
in `pty run --id`, pty.toml session id, and `pty rename` displayName
candidate paths.
Tests: 6 new regression tests in tests/display-name.test.ts covering
a 110-char displayName roundtripped through peek/send/tag/events/kill
plus the create case. Full suite: 1174 passed / 22 skipped / 0 failures.
list & gc ergonomics: vanished status, --summary/--status/age filters, gc --dry-run (closes #21)
Four changes, one PR:
1. Third session status `vanished` for the "daemon is gone, no exit
record written" case (SIGKILL / OOM / crash). Listed in its own
yellow-headered bucket with a warning icon so it doesn't blend into
cleanly-exited sessions. Reapable by `pty gc` like any other dead
session. TTL anchor falls back to createdAt so they can't accumulate
indefinitely.
2. `pty list --summary` (+ `--json --summary`) — compact counts and
oldest/newest pointers, respects all other filters.
3. `pty list --status <state>` and `--older-than/--newer-than <Ns|Nm|Nh|Nd>`
filters. Compose with `--filter-tag` and `--summary`. Grammar is
deliberately single-unit (no `1h30m`) to keep --help trivial.
4. `pty gc --dry-run` (`-n`) — preview what would be removed without
mutating anything. Covers exited AND vanished sessions AND orphan
`:l<pid>-<rand>` layout tags in one pass.
Client API:
- gc({ dryRun }), pruneOrphanLayoutTags({ dryRun })
- New `isGone(status)` helper — replaces hand-rolled
`status === "exited"` checks that should have included vanished all
along. Swept existing callers (run -a, peek fallback, pty up/down
cleanup, stats --all) to use it.
- New parseDuration/formatDuration exports for downstream tools.
Tests:
- duration.test.ts — full grammar coverage.
- list-filters.test.ts — vanished inference, --status, age filters,
--summary (text + json), filter composition.
- gc.test.ts — extended with --dry-run and vanished-session reaping.
726 → 728 local tests pass (+37 new), 0 failures.
feat(gc): replace long-running supervisor with cron-driven `pty gc`
The launchd-managed `pty-supervisor` daemon raced /Volumes/SSD's mount
on Mac boot: permanent sessions whose `dist/server.js` lived under the
external volume failed restart with MODULE_NOT_FOUND, exhausted 5
retries x 2s backoff within 10s, then were marked "no metadata" and
never came back without manual `pty up`. A long-running supervisor will
always have this class of bug — it can't be sure its dependencies are
ready when launchd fires it.
Replace it with a stateless reconciliation pass:
pty gc
invoked periodically by launchd (`StartInterval=30` by default) or any
other cron-driver. Three steps:
1. Orphan-children: sessions tagged `parent=<name>` whose parent's
metadata is gone OR whose parent's pid isn't alive get SIGTERM'd
and cleaned up. New user-facing tag.
2. Permanent respawn: every `strategy=permanent` session that's
exited/vanished is respawned via `spawnDaemon`. Sessions tagged
`ptyfile` re-read pty.toml to pick up edits.
3. Sweep: exited/vanished non-permanent sessions get `cleanupAll`'d
(the historic gc behavior).
Each run is independent — no persistent restart bookkeeping, no
MAX_RESTARTS, no backoff state to drift out of sync with reality.
Cron interval IS the rate limit; if /Volumes/SSD isn't mounted, the
invocation exits with ENOENT and the next tick tries again.
Install helper: `pty gc --print-launchd-plist [--interval=N]` prints
a minimal plist to stdout. No FDA wrapper, no compiled C binary, no
esbuild bundling — `<ProgramArguments>[pty, gc]</ProgramArguments>`
with `<StartInterval>`. User redirects to ~/Library/LaunchAgents/
and `launchctl load`s themselves.
Breaking changes:
- Deleted `pty supervisor *` commands entirely. Users who installed
the old supervisor should `launchctl unload` + remove the old
plist (see CHANGELOG for the exact commands).
- Deleted event types `session_restart`, `session_failed`,
`supervisor_start`, `supervisor_stop`. Added `session_respawn`.
- Deleted reserved tag `supervisor.status`. Added user-facing tag
`parent=<name>`.
- Dropped `strategy=temporary` (was functionally identical to no
strategy tag under the new sweep behavior).
- `gc()`'s return shape changed from `string[]` to a structured
`GcResult` with four buckets (`removed`, `killedOrphanChildren`,
`respawned`, `respawnFailed`). Public API.
Net delta: ~1830 lines deleted, ~485 added.

Emit display_name_change + tags_change; move metadata-mutation events
into the helpers so the programmatic API emits too.
Requested by pty-layout-claude: `pty rename` wrote metadata atomically
but emitted no event, so EventFollower consumers (pty-layout's pane
titles) had no signal to refresh and stayed stale until re-attach.
Same bundling for tag mutations since the smell was identical —
setDisplayName and updateTags now both emit on effective change:
- display_name_change: { session, ts, previous, value } with value
string | null. Skipped on no-op writes.
- tags_change: { session, ts, previous, value } carrying full
Record<string,string> snapshots so consumers can diff without
reasoning about updates vs. removals. Skipped on no-op.
While here, moved the state.set / state.delete emission from the CLI
down into setState / deleteState themselves. The CLI was the only
emission point before, which meant @myobie/pty/client consumers
calling setState directly got silent writes. Now every metadata-
mutation helper emits uniformly regardless of caller.
Added appendEventSync so the sync helpers can emit inline without
going async. Same MAX_LINES retention as the async path, with a
stat-based fast path.
Tests: 19 new across tests/metadata-events.test.ts (new) and
tests/state.test.ts — covering both events (add / change / clear /
remove), both formatEvent cases, live EventFollower delivery, CLI
end-to-end (pty rename, pty tag), no-op suppression, and the
programmatic-emission fix for setState/deleteState.

- `pty run --name <X>` now sets the displayName (any length, any printable
chars). The on-disk id is set by `--id <X>`. Both omitted → random short
id + auto-generated displayName. Both can be combined.
- `pty up` (pty.toml) gives every session a random short on-disk id. The
toml-derived `<prefix>-<sessionKey>` becomes the displayName, not the
filename. `pty up` re-run detection now matches by `(ptyfile,
ptyfile.session)` tag pair instead of by name.
- `pty.toml` gains two optional per-session fields: `id = "..."` to pin the
on-disk id and `display_name = "..."` to override the default label.
- `pty rename` validation: displayName uses the new permissive
`validateDisplayName` (≤ 500 chars, no slashes / null / newlines /
control bytes) instead of the strict `validateName` (sock-filename
charset, sock-path length). Strict validation is reserved for ids.
- `SessionMetadata.displayName` is now preserved through exit (previously
`saveExitMetadata` dropped it).
- `PtySessionDef.name` replaced by `displayName` + optional `id`;
`shortName` unchanged. External callers (`pty kill`, `peek`, `send`,
`attach`) are unaffected — they already resolved by either field via
`resolveRef`.
- `spawnDaemon`'s bundled-context fallback now passes `--id` (instead of
`--name`) to the CLI delegation path and explicitly threads
`displayName` / `--no-display-name`.
Tests
- New `tests/up-name-decouple.test.ts` covers random id, long-prefix
support, `(ptyfile, ptyfile.session)` re-run lookup, pty.toml `id` and
`display_name` overrides, and operations resolving by displayName.
- Existing tests migrated from `--name <id>` to `--id <id>` for tests
whose intent was pinning the on-disk identifier. `display-name.test.ts`
rewritten to test the new `--id` / `--name` semantics including
long-label, kernel-limit rejection, and id/name collision rejection.
Full suite green (1168 passed / 22 skipped / 1190 total).
* fix(cli): drop validateName from session-resolution paths
Long displayNames could be created via `pty run --name <long>` but
operating on them (`pty peek|send|kill|tag|events|attach|restart|rm`)
failed with the `validateName` sock-path kernel-limit error — the
strict validator was running on the user-supplied ref BEFORE
resolveRef did the lookup. The strict validator's job is to gate
on-disk id creation, not session-reference resolution.
Fix per schickling-assistant's PR #45 review:
- Drop the validateName(ref) block from 7 sites in cli.ts: attach,
peek, send, events, tag, kill, rm, cmdRestart, and tag-multi by-name
selector.
- Add resolveRef at the supervisor forget/reset dispatch sites so
cmdSupervisorForget/Reset receive a resolved name (their bodies
drop their own redundant validateName as a consequence).
- Drop the redundant validateName inside cmdRestart — its dispatcher
already resolved the ref.
validateName remains in place where it belongs: on-disk id creation
in `pty run --id`, pty.toml session id, and `pty rename` displayName
candidate paths.
Tests: 6 new regression tests in tests/display-name.test.ts covering
a 110-char displayName roundtripped through peek/send/tag/events/kill
plus the create case. Full suite: 1174 passed / 22 skipped / 0 failures.
Emit display_name_change + tags_change; move metadata-mutation events
into the helpers so the programmatic API emits too.
Requested by pty-layout-claude: `pty rename` wrote metadata atomically
but emitted no event, so EventFollower consumers (pty-layout's pane
titles) had no signal to refresh and stayed stale until re-attach.
Same bundling for tag mutations since the smell was identical —
setDisplayName and updateTags now both emit on effective change:
- display_name_change: { session, ts, previous, value } with value
string | null. Skipped on no-op writes.
- tags_change: { session, ts, previous, value } carrying full
Record<string,string> snapshots so consumers can diff without
reasoning about updates vs. removals. Skipped on no-op.
While here, moved the state.set / state.delete emission from the CLI
down into setState / deleteState themselves. The CLI was the only
emission point before, which meant @myobie/pty/client consumers
calling setState directly got silent writes. Now every metadata-
mutation helper emits uniformly regardless of caller.
Added appendEventSync so the sync helpers can emit inline without
going async. Same MAX_LINES retention as the async path, with a
stat-based fast path.
Tests: 19 new across tests/metadata-events.test.ts (new) and
tests/state.test.ts — covering both events (add / change / clear /
remove), both formatEvent cases, live EventFollower delivery, CLI
end-to-end (pty rename, pty tag), no-op suppression, and the
programmatic-emission fix for setState/deleteState.
pty tag-multi: multi-session tag operations + harden bulk pty tag
New sibling command pty tag-multi for multi-session work. Single-
session pty tag stays as-is; pty tag-multi lives next to it so a
fingerslip cant accidentally rewrite the wrong scope.
Three mutually-exclusive selectors:
<name>... explicit list (resolved up-front; if any
name is unresolvable the command aborts
before any write — no partial application)
--filter-tag k=v sessions matching tag(s); repeatable AND
--all every session
No ops = read mode (per-session tag dump, text or --json returning
{ name → tags }). Any ops (k=v / --rm k) flips to write mode. --all
writes are destructive across the whole session dir, so they require
--yes / -y; without it the command prints the matched count and
exits non-zero, no writes performed. Empty match (filter or --all
over an empty dir) is exit 0 with "0 sessions matched."
Each successful write goes through the existing atomic updateTags
+ tags_change event flow per-session; per-session no-ops emit
nothing. Selector resolution is upfront for explicit lists, lazy
for filter / --all (just listSessions).
Also hardens the existing single-session pty tag while we're here:
- rejects empty key in `=value`
- rejects --rm "" (empty key for removal)
- clearer error for --rm at end of argv with no key
- tightened parsing comments
Tests:
tests/tag-multi.test.ts (38 tests) — read explicit list, read
selectors (--filter-tag single/repeated/empty, --all on empty
dir), write explicit list (events fire per session, no-op on
one peer doesnt suppress the others, upfront-unresolvable
aborts), write selectors (--filter-tag, --all without --yes
rejected, --all --yes applied, -y short form), selector mutex
(--all+filter, --all+names, filter+names, no selector, ops
without selector), ops parsing errors (empty key, --rm at end,
--rm "", --filter-tag without value, --filter-tag without =,
multi-= splits on first =, set+rm same key wins for rm to
match pty tag).
tests/tag-bulk.test.ts (29 tests) — pin the existing pty tag
contract: bulk set, bulk rm, combined set+rm, position
independence, empty key/value edges, atomic events (one
tags_change per call), no-op detection, partial no-op + real
change, displayName resolution.
CHANGELOG and README reflect both.

Add supervisor, mutable tags, peek --wait/--full, and hardening
Session supervisor watches strategy tags and restarts permanent
sessions with exponential backoff. Runs as a foreground process,
integrates with launchd via esbuild bundling. Mutable tags via
pty tag command. pty kill/down properly handle supervised sessions.
Also: peek --wait blocks until text appears, peek --full shows
scrollback, events --wait blocks for event types, interactive TUI
shows [permanent] markers with color, 10s supervisor scan interval,
supervisor state in its own subdirectory, defensive meta.args
handling, and isolated shell test sessions.
feat(gc): replace long-running supervisor with cron-driven `pty gc`
The launchd-managed `pty-supervisor` daemon raced /Volumes/SSD's mount
on Mac boot: permanent sessions whose `dist/server.js` lived under the
external volume failed restart with MODULE_NOT_FOUND, exhausted 5
retries x 2s backoff within 10s, then were marked "no metadata" and
never came back without manual `pty up`. A long-running supervisor will
always have this class of bug — it can't be sure its dependencies are
ready when launchd fires it.
Replace it with a stateless reconciliation pass:
pty gc
invoked periodically by launchd (`StartInterval=30` by default) or any
other cron-driver. Three steps:
1. Orphan-children: sessions tagged `parent=<name>` whose parent's
metadata is gone OR whose parent's pid isn't alive get SIGTERM'd
and cleaned up. New user-facing tag.
2. Permanent respawn: every `strategy=permanent` session that's
exited/vanished is respawned via `spawnDaemon`. Sessions tagged
`ptyfile` re-read pty.toml to pick up edits.
3. Sweep: exited/vanished non-permanent sessions get `cleanupAll`'d
(the historic gc behavior).
Each run is independent — no persistent restart bookkeeping, no
MAX_RESTARTS, no backoff state to drift out of sync with reality.
Cron interval IS the rate limit; if /Volumes/SSD isn't mounted, the
invocation exits with ENOENT and the next tick tries again.
Install helper: `pty gc --print-launchd-plist [--interval=N]` prints
a minimal plist to stdout. No FDA wrapper, no compiled C binary, no
esbuild bundling — `<ProgramArguments>[pty, gc]</ProgramArguments>`
with `<StartInterval>`. User redirects to ~/Library/LaunchAgents/
and `launchctl load`s themselves.
Breaking changes:
- Deleted `pty supervisor *` commands entirely. Users who installed
the old supervisor should `launchctl unload` + remove the old
plist (see CHANGELOG for the exact commands).
- Deleted event types `session_restart`, `session_failed`,
`supervisor_start`, `supervisor_stop`. Added `session_respawn`.
- Deleted reserved tag `supervisor.status`. Added user-facing tag
`parent=<name>`.
- Dropped `strategy=temporary` (was functionally identical to no
strategy tag under the new sweep behavior).
- `gc()`'s return shape changed from `string[]` to a structured
`GcResult` with four buckets (`removed`, `killedOrphanChildren`,
`respawned`, `respawnFailed`). Public API.

Readline-style shortcuts in the interactive filter input (closes #24)
The pty / pty i / pty interactive picker's filter input was append-
only — backspace + printable chars, no cursor, no word motion, no
kill-line. Editing longer queries was awkward compared to the shell
prompts people build muscle memory for.
Fixed at two layers:
1. applyTextKey (src/tui/widgets/form.ts) — the shared text-field
helper — gains ctrl+w (delete previous word) and ctrl+k (kill to
end of line). It already had backspace / delete / arrows / home
/ end / ctrl+a / ctrl+e / ctrl+u / alt+arrow and alt+b/f word
motion. So every consumer (interactive filter, form widget,
command palette, prompt bar) picks up the new shortcuts for free.
2. Interactive filter (src/tui/interactive.ts) — replaces the hand-
rolled append/slice key handling with a TextFieldState signal
routed through applyTextKey. The filter line renders via
renderFieldNodes so the cursor paints on top of the char under
it (inverse-video) without shoving neighbors sideways. Typing
resets the selection to 0 as before; pure cursor motion (home,
end, arrows) preserves the current selection.
Tests:
- widgets-form.test.ts: 8 new unit tests for ctrl+a, ctrl+e, ctrl+w
(end-of-line, mid-string, trailing-whitespace boundary, empty
field) and ctrl+k (mid-cursor, at-end).
- tui.test.ts: 2 new end-to-end tests through a real PTY confirming
ctrl+u clears the filter in one keystroke and ctrl+w removes the
trailing word, updating the rendered filter line.
