fix(tui): split terminal tab title from window title - #74683
Merged
Conversation
Terminal.app truncates background tab titles from the left, so a single long OSC 0 string (marker · session · model · cwd) leaves only the tail visible — usually the cwd or process name. Emit OSC 1 (icon/tab) with just the short session title and OSC 2 (window) with the full composed string, so background tabs show the session name instead of the cwd tail.

What changed and why
Terminal.app truncates background tab titles from the left. The TUI was emitting a single OSC 0 (set title+icon) with the full composed string
marker · sessionTitle · model · cwd, so a background tab only showed the tail — usually the cwd or process name likepython— instead of the session name at the front.useTerminalTitlenow accepts{ tab, window }to emit two separate sequences:⏳ session title⏳ session title · model · cwdBackground tabs now show the session name. The window title bar keeps the full string. When a single string is passed (existing callers), behavior is unchanged — still OSC 0.
How to test
Cmd+I) — should show the fullmarker · session · model · cwdstring.Related — superseded PRs
This PR fixes the TUI (Ink/React) tab title. The classic CLI (prompt_toolkit) is a separate code path — #74654 is the complementary CLI implementation and remains open.
The following stale CLI PRs were closed as superseded by #74654:
#5505 (the feature issue) stays open until #74654 merges for the CLI side; the TUI side is fixed here.
