+# `zsh-done`
+
+This is a Zshell plug-in to automatically receive notifications after a
+long-running process ends.
+
+## Dependencies
+
+* If you want notifications with icons on macOS, install `terminal-notifier`.
+* If you are using `swaywm`, install `jq`.
+
+## Settings
+
+### Command duration threshold
+
+```zsh
+DONE_MIN_CMD_DURATION=15 # Default: 5
+```
+
+### Command deny-list regex
+
+Uses `grep -P` (Perl syntax) to filter out commands that should never notify.
+
+```zsh
+DONE_MIN_CMD_DURATION='^\sgit (?!push|pull|fetch)' # Default: ''
+```
+
+### Play a sound when sending notification
+
+When using `terminal-notifier`, play a sound when sending the notification,
+otherwise ring the terminal bell.
+
+```zsh
+DONE_NOTIFY_SOUND=1 # Default: 0
+```
+
+### Notification levels
+
+When using `notify-send` or `notify-desktop`, use a specific urgency level for
+your notifications.
+
+```zsh
+DONE_NOTIFICATION_URGENCY_LEVEL=low # Default: normal
+DONE_NOTIFICATION_URGENCY_LEVEL_FAILURE=normal # Default: critical
+```
+
+### Do not show notification for visible windows (`sway` only)
+
+```zsh
+DONE_SWAY_IGNORE_VISIBLE=1 # Default: 0
+```
+
+### Allow sending notifications on non-graphical systems
+
+This also requires you to define the `done_send_notification` function.
+
+```zsh
+DONE_ALLOW_NONGRAPHICAL=1 # Default: 0
+
+done_send_notification() {
+    local exit_status="$1"
+    local title="$2"
+    local message="$3"
+    # Use OSC-777 to send a notification (only with compatible terminals)
+    echo -ne "\e]777;notify;$title;$message\e\\"
+}
+```
+
+### Customize the notification texts
+
+You can define `done_format_title` and `done_format_message` to customize the
+title and message of your notifications.
+
+```zsh
+done_format_title() {
+    local exit_status="$1"
+    local cmd_duration="$2"
+    local last_command="$3"
+
+    if [ "$exit_status" -eq 0 ]; then
+        echo "SUCCESS (__done_humanize_duration "$cmd_duration")"
+    else
+        echo "FAIL (__done_humanize_duration "$cmd_duration")"
+    fi
+}
+
+done_format_message() {
+    local exit_status="$1"
+    local cmd_duration="$2"
+    local last_command="$3"
+
+    printf '%s (%s)' "$last_command" "$exit_status"
+}
+```
+
+## More information and alternatives
+
+This plug-in was largely inspired by [the fish package of the same
+name](https://github.com/franciscolourenco/done), and steals much of the "is the
+shell focused" logic from it.
+
+Unlike the `fish` plug-in, this one does not have support for Windows wired in.
+
+Alternative plug-ins:
+* [`zsh-notify`](https://github.com/marzocchi/zsh-notify)
+* [`zsh-background-notify`](https://github.com/t413/zsh-background-notify)
