2026-08-11feat: keep the outer terminal window title in sync with the session (#2627)David Heinemeier Hansson
* feat: keep the outer terminal window title in sync with the session Herdr emulates the terminals in its panes, so an OSC 0/OSC 2 title written inside a pane stops at Herdr and never reaches the terminal Herdr itself runs in. That outer title is what window managers read for title bars, tab bars, and group bars, so it kept showing whatever the shell or ssh happened to leave behind. Add `ui.window_title`, rendered from {hostname}, {workspace}, {tab}, {pane}, and {terminal_title}, and push it to the foreground client whenever it changes. It renders on the server, so {hostname} names the machine the panes actually run on rather than the machine a thin remote client runs on, and it is gated on a pending render so an idle loop never pays for it. A title is only remembered as delivered once a foreground client takes it, so the first client to attach is written to rather than skipped. `client.window_title.set` still wins over the configured title, and clearing it now hands the title back to `ui.window_title` instead of only "herdr". * fix: deliver the outer window title to a newly attached client ClientConnected assigns the foreground client directly rather than going through promote_client_to_foreground, so clearing the sent-title cache there missed the case that matters most: attaching a second terminal to a running session. The title was usually unchanged, so the sync returned early and the new terminal kept whatever its shell or ssh had left. Key the cache on the client that received the title instead of relying on every foreground assignment to invalidate it. * perf: keep hidden pane output off the window title path Output from a hidden or background pane sets needs_render without setting needs_full_render, and the retained render plan then skips presentation for it entirely. Syncing the title on needs_render meant every coalesced hidden-output tick still formatted, sanitized, and allocated a title that could not have changed, against the hidden-source early exit AGENTS.md requires. Every input to the title is app state, which always requests a full render, so gate on that instead. The one exception is the focused pane's own terminal title, which arrives through PTY parsing, so ask for a full render when that changes and the configured title uses it. * fix: only cache a window title a client writer received * fix: carry an api set window title across a live handoff * fix: make outer window title updates event-driven --------- Co-authored-by: Ogulcan Celik <ogulcancelik@gmail.com>

2026-07-25feat: switch IME to ASCII in prefix mode on Windows (Korean IME) (#1823)joonhwan
* feat: switch IME to ASCII in prefix mode on Windows Extend switch_ascii_input_source_in_prefix to Windows: detect IME state via WM_IME_CONTROL and toggle to ASCII with SendInput for the Korean IME. Other IME languages are detected and left unchanged. refs #1802 * docs: clarify Windows (Korean IME) support for prefix ASCII switching Follow-up to the Windows prefix ASCII switch, which extended switch_ascii_input_source_in_prefix to Windows but left the surrounding text describing macOS only. - Settings row label: "(macOS)" -> "(macOS/Windows)", plus its test. - Generalize the Windows behavior wording to "switches the IME to English (ASCII) input" in the config-reference.json entry and the model.rs doc comment, and state that Windows support is currently limited to the Korean IME. - Add a :::caution aside noting the Korean-IME-only limitation to the en/ja/zh preview docs, keeping the three translations in sync. refs #1802 * fix: warn when prefix IME toggle injection is incomplete SendInput can queue fewer events than requested (for example when blocked by UIPI), which would otherwise leave the IME silently stuck in ASCII or native mode. Log a warning with the sent and expected counts so the failure is diagnosable. refs #1802 * fix: guard prefix IME restore and correct open-status naming Address maintainer review on the Windows prefix ASCII switch: - Restore only when safe: store the foreground window at switch time and, before toggling back, require that the same window is still focused and the IME is still in English. This stops restore from toggling another application or overriding a manual return to Hangul during prefix mode. - Report injection success from send_vk_tap and only arm restoration when the initial toggle landed; on a partial injection retry the dropped key-up so a key is not left logically held down. The injection policy is split into send_vk_tap_with(inject) so the success, partial, and failure branches are unit-tested without the real SendInput. - Correct the WM_IME_CONTROL sub-command naming: 0x0005 is IMC_GETOPENSTATUS (IME open state), not IMC_GETCONVERSIONMODE. Behavior is unchanged; the constant, comments, and tests now describe the open-status read. refs #1802 * fix: bound IME open-status read with a timeout The prefix IME switch reads IMC_GETOPENSTATUS via WM_IME_CONTROL, which crosses into the terminal-emulator process. A plain SendMessageW would block herdr's client thread until that process responds, indefinitely if it hangs. Read through SendMessageTimeoutW with SMTO_ABORTIFHUNG and a short timeout instead; on timeout the switch is skipped and restore does nothing, so a hung host process can no longer freeze prefix-mode entry or exit. refs #1802 * fix: preserve windows ime restoration after partial injection refs #1802 --------- Co-authored-by: Ogulcan Celik <ogulcancelik@gmail.com>

2026-07-05fix: switch prefix ASCII input source on the foreground client (#1016)ppggff
* fix: switch prefix ASCII input source on the foreground client The macOS prefix ASCII-switch ran in the headless server, whose TISCopyCurrentKeyboardInputSource read is a stale per-process cache (refreshed only via a main-run-loop notification the server never pumps), so prefix could leave the terminal on the wrong input source. Forward it to the foreground client, like clipboard: sync_prefix_input_source emits AppEvent::PrefixInputSource as an intent; the server forwards it to the foreground client and the monolithic app applies it in-process via RealPrefixInputSource, which pumps its main run loop before the stale TIS read. Key it on Mode::wants_ascii_input so multi-level prefix commands keep ASCII until returning to the terminal, and restore the IME for rename text entry. Adds ServerMessage::PrefixInputSource to the already-unreleased protocol 15. refs #774 * fix: keep prefix input-source switch out of the headless server process An App-internal drain (the exhaustive drain at the top of handle_api_request, reachable from prefix-key runtime mutations) can consume a queued PrefixInputSource intent before the server's forwarding drain sees it, applying the TIS switch in the headless server process and stranding the restore state. Gate the in-process switch on App.local_input_source_switch, disabled by the headless server alongside the other local side effects, so a swallowed intent degrades to a skipped switch. Widen the forwarding-bypass maintenance test to the handle_internal_event_with_prefix_sync wrapper. refs #774 * docs: clarify prefix input-source comments and flag docs refs #774 * fix: bump protocol for prefix input source refs #774 --------- Co-authored-by: Ogulcan Celik <ogulcancelik@gmail.com>
