responses.ts

// This is meant to be used in a trigger as such:
// {
//   id: 'Some tankbuster',
//   regex: Regexes.startsUsing({source: 'Ye Olde Bosse', id: '666'}),
//   condition: Conditions.caresAboutMagical(data),
//   response: Responses.tankbuster(),
// },
//
// Note: Breaking out the condition like this lets people override it if they
// always (or never) want to know about it, rather than hiding the logic inside
// the tankbuster callback with a "is healer" check.
//
// If data.role is used, it should be only to differentiate between alert levels,
// and not whether a message is sent at all.
//
// Although this is not true of `response: ` fields on triggers in general,
// all responses in this file should either return an object or a single
// function that sets outputStrings and returns an object without doing
// anything with data or matches.  See `responses_test.js`.
