Gcal ➔ Slack

gcal-slack-update automatically changes your status in multiple Slack teams, depending on the current event in your Google Calendar.

It is designed to run periodically from a cron job and, during each execution, it checks whether the current event Title in Google Calendar contains the match-text defined in the set of configuration rules received as input.

Example of an input file in rules-example.conf:

rules = [
  {
    match-text = "testing this"
    status-emoji = ":smile:"
    status-text = "It works"
  }, 
  {
    match-text = "another test"
    status-emoji = ":+1:"
    status-text = "Count me in"
  },
]

Configurations	Description	Maps to…
match-text	Case insensitive string which can appear anywhere in the searched field	Google Calendar: Event Title
status-emoji	The symbol to display as the status	Slack: Status Emoji
status-text	The status’ description (can also contain emojis)	Slack: Status Text

Authentication is read from a file named auth.conf (see example in auth-example.conf):

slack-token = "xoxp-legacy-token"

To generate such a token, go to the legacy tokens Slack page of the workspace where you wish to update the status.

Local Installation

• Get latest release from the repo releases page and unzip it to some location
• Make sure the execution script has execute permissions: chmod a+x bin/gcal-slack-update
• Copy file auth-example.conf into auth.conf and update with your token for Slack
• Copy file to rules.conf and customise it to your needs, as you prefer
• Periodically run the command ./bin/gcal-slack-update rules.conf with the frequency you wish to update status

Ideas 💡

• Change status in multiples Slack teams simultaneously!
• Support multiple Google Calendars?
• Search for matches in other event fields? (e.g. description, location)
• Support regex patterns to match events?
• Configure sbt-native-packager to ensure that the universal script files in ./bin have execute permissions
