slackbot

Slack RTM based bot.

Slackbot is event driven and support cron tasks.

Below illustrate you a simple demo. It is so simple that just listen to some events and schedule cron tasks. Now, I only implement the JSON parser and resolver. So you can only play with JsonEvent. If you wanna interact with Slack, methods is helpful. methods implements some actions such as postMessage which can send message to certain channel you specified.

String DEFAULT_TOKEN = "xxxx";
String DEFAULT_CHANNEL = "yyyy";

new Slack(DEFAULT_TOKEN,
    new SlackResolver<>(new BasicParser())
        .listen(RTMEvent.HELLO, (context) ->
            System.out.println(">connected to slack.")
        })
        .listen(RTMEvent.MESSAGE, (context) -> {
            System.out.println(">message.");
            JsonNode msg = context.event().getMessage();
            print(msg);
        })
        .listen(RTMEvent.GOODBYE, (context) -> /** blah... blah... */)
        .schedule("0 */1 * * * ?", (context) -> {
            String text = "Schedule Message: " + (new Date());
            context.methods().chatPostMessage(DEFAULT_CHANNEL, text, null, null);
        })
).connect();

Also, I supply you message materials.

Block is rich-text

They are a series of components that can be combined to create visually rich and compellingly interactive messages. I implement Context Image Divider Section blocks.
