Pending Changes

These are some accepted changes to the RiveScript specification that have yet to be implemented in all of the primary implementations.

The Working Draft will only be updated to document these changes when all of the primary implementations support them.

In the following lists of implementations that support each feature, the GitHub commit that implements the feature is linked. In the case where there isn't an associated commit, it means that implementation included the feature from the beginning or the commit that added the feature hasn't been found yet.

UTF-8 Support

Allows using foreign characters in triggers, loosens up the filtering of input messages, and allows for the user to tell the bot their e-mail address without the @ and dot symbols being removed.

Support:

Punctuation Stripping in UTF-8 Mode

Support:

  • Go
  • Java
  • JavaScript
  • Perl
  • Python

  • Go
  • Java (@e09049e)
  • JavaScript
  • Perl
  • Python

Support:

  • Go
  • Java
  • JavaScript
  • Perl
  • Python

Arrays in Responses

This repurposes arrays to be usable in responses. A tag like (@array) is expanded into {random}ARRAY{/random}, where "ARRAY" is the pipe-delimited contents of the array.

Example:

! array greek = alpha beta gamma

+ say a greek letter
- Here you go: (@greek)

// This is equivalent to:
+ say a greek letter
- Here you go: {random}alpha|beta|gamma{/random}

Support:

  • Go
  • Java
  • JavaScript (@fdc33ea)
  • Perl
  • Python

Recursive Load Directory

This makes the loadDirectory() function search recursively for RiveScript files.

Support:

  • Go
  • Java
  • JavaScript (@07e4e93)
  • Perl
  • Python

Last updated: 2016-03-08

Nested Arrays

This makes arrays able to embed each other, like !array colors = @primary @chromatic orange brown pink. Arrays are only expanded at reply fetching time, so they can be defined in any order in any file.

Support:

  • Go
  • Java
  • JavaScript
  • Perl
  • Python (#22)
