A Slack bot for fetching lunch menu announcements from selected Facebook pages.
Use the Universal plugin to build a deployable artifact (check the link for other archive formats):
sbt universal:package-bin
Copy it to a destination of your choice or unzip it directly as such:
unzip -d /opt/ target/universal/slack-lunch-bot-0.1-SNAPSHOT.zip
Run the bot by executing the provided script:
/opt/slack-lunch-bot-0.1-SNAPSHOT/bin/slack-lunch-bot
You can use the provided configuration file as a template:
cp conf/application.conf.example conf/application.conf
Setup a bot user account as described here. Make sure, that the bot is a member of the target channel (e.g. #lunch or whatever you prefer).
Set the api token and the channel name in the slack section of the config.
Setup a Facebook application here. It will be used for querying the Facebook pages of your choice.
Set the app id and the app secret in the facebook section of the config. Put relevant page IDs in the same section (for https://www.facebook.com/SomeRestaurant the ID is simply SomeRestaurant).
Check the akka.quartz section for a relevant cron expression. Once triggered, the bot will check each page for the latest Facebook post, that was made on that day (hopefully, it should be a menu), and publish it to Slack.
