// NotifyDesktop sends a desktop notification on Linux via the `notify-send`
|
|
// binary (libnotify). It is impure: it shells out to an external program.
|
|
//
|
|
// Degradation is intentional and silent: if `notify-send` is not on the PATH,
|
|
// the function returns nil without error. A machine without a notification
|
|
// server is not a failure condition for the caller — the notification is simply
|
|
// skipped. Only a real execution failure of an existing `notify-send` is
|
|
// returned (wrapped with context).
|
|
//
|
|
// When `notify-send` is present it runs:
|
|
//
|
|
// notify-send --app-name=fleetview --urgency=normal -- <title> <body>
|
|
//
|
|
// The `--` separator guarantees that a title or body starting with "-" is
|
|
// treated as positional text, not as a flag. An empty title falls back to a
|
|
// sensible default; an empty body is accepted by notify-send as-is.
