"""Terminal-native desktop notifications: OSC 9 and Warp's OSC 777 CLI-agent protocol.
|
||||
|
||||
Both emitters ride on the existing ``display.bell_on_prompt`` /
|
||||
``display.bell_on_complete`` flags (see ``cli._ring_bell``) — no extra config.
|
||||
|
||||
- **OSC 9** (``ESC ] 9 ; <body> BEL``): Ghostty, iTerm2, Kitty and WezTerm
|
||||
raise an OS notification; terminals that don't know the sequence drop it.
|
||||
- **OSC 777** (``ESC ] 777 ; notify ; warp://cli-agent ; <json> BEL``): Warp's
|
||||
structured CLI-agent protocol (tab status + notification mailbox). Only sent
|
||||
when Warp advertises support and the build is newer than the last release
|
||||
that set the protocol var without being able to render the payload.
|
||||
|
||||
Sequences are written to ``/dev/tty`` because prompt_toolkit's stdout wrapper
|
||||
can buffer or strip raw escapes; when ``/dev/tty`` can't be opened (Windows,
|
||||
no controlling terminal) they fall back to ``sys.stdout``. Never raises.
