feat(terminal-launch): spawn new sessions into tmux pane when in TMUX (#74)#193
Merged
Conversation
When jcode is launched from inside an attached tmux session, every
"open in new terminal" path (resume picker, /split, /selfdev, list_sessions)
previously launched an entirely new terminal emulator. That blew the
user out of tmux and lost the session/window grouping.
Detect TMUX via the $TMUX env var (tmux always sets this for processes
inside an attached pane) and add a tmux dispatch arm in
build_spawn_command:
tmux split-window -d -c <cwd> '<shell>' \; select-layout tiled
`-d` keeps focus on the originating pane; `select-layout tiled` re-flows
so the new pane is visible. Add "tmux" to resume_terminal_candidates
ahead of the GUI emulators on both Linux and macOS so it wins
naturally when present.
Test `detected_resume_terminal_recognizes_tmux_via_tmux_env` covers
detection priority.
Ports upstream PR 1jehuang#78. Local
fork's spawn dispatch lives in `crates/jcode-terminal-launch` rather
than `src/cli/tui_launch.rs` (upstream's layout), so the tmux match
arm is added there and reused by all callers automatically.
Closes #74

Notes / scope deviation from upstream
Upstream PR 1jehuang#78 puts the dispatch in
src/cli/tui_launch.rsnext to the--standaloneflag handling. This fork extracted spawn dispatch intocrates/jcode-terminal-launch(and removed--standaloneper #102), so the tmux match arm is added there and reused by all callers automatically.
