config

{
  "host": "",
  "port": ,
  "tls": true,
  "tlsOptions": { "rejectUnauthorized": false },
  "username": "",
  "password": "",
  "onNotify": "/usr/bin/mbsync test-%s",
  "onNotifyPost": {"mail": "/usr/bin/notmuch new && notify-send 'New mail arrived'"},
  "boxes":
    [
      "box1",
      "box2/box3"
    ]
}
	onNotify:
		[string]: shell command to run on any event
		[object]: shell commands to run on for each type of event
			keys: "mail" for new mail, "update" for existing messages updates, "expunge" for messages deletions
    onNotifyPost:
		[string]: shell command to run after onNotify event
		[object]: shell commands to run after onNotify for each type of event
			keys: "mail" for new mail, "update" for existing messages updates, "expunge" for messages deletions

extra options

    onSIGNAL: a command to run when `SIGNAL` is received.
    onSIGNALpost: a command to run after onSINGAL

Example:

{
  ...
  "onSIGTERM": "/usr/bin/mbsync -a",
  "onSIGTERMpost": "echo 'Bye-Bye'"
  ...
}

config as a node module

Since we load the config file with require(), we can get away with any nodejs module instead of just json. This allows us to be more flexible with the configuration.

In particular, you one can use it to load password from a script rather than having to store it in plain text.

Important: config-module must be requirable (in your $NODE_PATH or given by an absolute path)

Using the latest (>0.12) version of nodejs, one can write myconfig.js as follows. Assuming the script ~/getpass.sh prints out your password. (execSync is a v0.12 feature)

    var child_process = require('child_process');

    function getStdout(cmd) {
        var stdout = child_process.execSync(cmd);
        return stdout.toString().trim();
    }

    exports.host = "<host>"
    exports.port = <port>;
    exports.tls = true;
    exports.tlsOptions = { "rejectUnauthorized": false };
    exports.username = "<user>";
    exports.password = getStdout("~/getpass.sh");
    exports.onNotify = "<sync command>"
    exports.onNotifyPost = "<command>"
    exports.boxes = [ "box1", "box2", "some/other/box" ];

Then you can use

    $ imapnotify -c ~/.config/imap_notify/myconfig.js

Thanks Matthew, for pointing that out!

substitutions

%s in onNotify and onNotifyPost is replaced by the box name.

/ symbol (slash) is replaced by - symbol (minus) so that inbox/junk becomes inbox-junk
