Brain (RiveScript master)

Create a Brain object which handles the actual process of fetching a reply.

string reply (string user, string msg[, scope])

Fetch a reply for the user.

string|Promise processCallTags (string reply, object scope, bool async)

Process <call> tags in the preprocessed reply string. If async is true, processCallTags can handle asynchronous subroutines and it returns a promise, otherwise a string is returned

string _getReply (string user, string msg, string context, int step, scope)

The internal reply method. DO NOT CALL THIS DIRECTLY.

• user, msg and scope are the same as reply()
• context = "normal" or "begin"
• step = the recursion depth
• scope = the call scope for object macros

string formatMessage (string msg)

Format a user's message for safe processing.

string triggerRegexp (string user, string trigger)

Prepares a trigger for the regular expression engine.

string processTags (string user, string msg, string reply, string[] stars, string[] botstars, int step, scope)

Process tags in a reply element.

All the tags get processed here except for <call> tags which have a separate subroutine (refer to processCallTags for more info)

string substitute (string msg, string type)

Run substitutions against a message. type is either "sub" or "person" for the type of substitution to run.
