--- Overseer component: show task output in a Snacks window docked to the
|
|
||||||
--- bottom of the editor, toggleterm-style: the window is focused and dropped
|
|
||||||
--- into terminal mode when the task starts (and whenever the buffer is
|
|
||||||
--- re-entered). Output stays on screen after the task exits; <CR> or q then
|
|
||||||
--- close the window (while running, keys still go to the process; q in
|
|
||||||
--- normal mode always closes).
|
|
||||||
---
|
|
||||||
--- The task's own terminal buffer (owned by the jobstart strategy, so exit
|
|
||||||
--- status / output parsing keep working) is placed in a single shared
|
|
||||||
--- bottom window. A newly started task takes the window over, so the most
|
|
||||||
--- recent run is always the one visible. `fixbuf = false` lets overseer swap
|
|
||||||
--- the buffer in place on restart (Task:start -> util.replace_buffer_in_wins).
