1.14.0 - July 23, 2016

Changes

1.14.0 Jul 23 2016

• Make the session manager pluggable and replaceable. RiveScript still uses
  an in-memory store for user variables, but this can be swapped out with a
  replacement that puts user variables somewhere else, like Redis or MySQL.
  The constructor accepts a session_manager parameter to use your own
  session manager based on the rivescript.sessions.SessionManager class.
• Make the RiveScript Parser module (rivescript.parser) more developer
  friendly by removing the parent RiveScript module as a dependency. The
  parser can be used as a stand-alone module if all you want to do is parse
  and validate RiveScript code.
• The log parameter to the constructor may now be an already opened file
  handle (opened in write or append mode) instead of a string, if you already
  have a file handle ready.
• Add two examples to the eg directory:
  • eg/sessions replaces the in-memory session store with one that uses
    a Redis cache instead.
  • eg/parser shows how to use the RiveScript Parser module.
• Fix a bug where atomic triggers that contain a {weight} tag were unable
  to be matched properly.
• Reorganize the unit tests into many smaller files instead of one large one.

1.13.0 - July 21, 2016

Changes

1.13.0 Jul 21 2016

• Restructure the code to keep it on par with the JavaScript and Go versions (PR #30):
  • rivescript.parser now contains all the parsing code:
    parse() and check_syntax() are moved here.
  • Triggers are stored internally in only one place now, like in the
    JavaScript and Go versions. This makes some internal mappings simpler as
    they now point to common references and don't duplicate data in memory.
  • Note: Most of the new rivescript.* modules are still
    private-use-only, even though many internal functions lost their
    underscore prefixes. You should still only use the API functions exposed
    by rivescript.rivescript or what is exported by the top level package.
    The rivescript.parser API will be more public-facing in the future to
    help with third party integrations (currently it still relies on a Python
    object with methods _say and _warn).
• Refactor the RiveScript interactive mode (rivescript.interactive) to use
  argparse instead of getopt and add a pretty ASCII logo.
• Add shell.py as a possibly easier-to-access (and certainly
  easier-to-discover) shortcut to running RiveScript's interactive mode.
  It accepts all the same options and works the same as before.

1.12.3 - July 8, 2016

Changes

1.12.3 Jul 8 2016

• Fix the Python object macro handler to use six.text_type on the return
  value, allowing Python 2 objects to return Unicode strings.

1.12.2 - May 31 2016

Changes

1.12.2 May 31 2016

• Fix a couple of bugs with set_uservars().

1.12.1 - May 31 2016

Changes

1.12.1 May 31 2016

• Added API functions: get_global(name), get_variable(name), and
  set_uservars(user || dict[, dict]) -- the latter is for setting many
  variables for a user at once, or for setting many variables for many users.
  Refer to the API documentation for details.

1.12.0 - May 10 2016

Changes

1.12.0 May 10 2016

• Add support for nested arrays, like !array colors = @rgb white black
  (PR #22)

Release 1.10.0 - Feb 16 2016

Changes

• Add configurable unicode_punctuation attribute to strip out punctuation
  when running in UTF-8 mode.

Release 1.8.1 - Nov 19 2015

Changes

• Add @ to the list of characters that disqualifies a trigger from being considered "atomic"

Release 1.8.0 - Oct 10 2015

Changes

• New algorithm for handling variable tags (<get>, <set>, <add>, <sub>,
  <mult>, <div>, <bot> and <env>) that allows for iterative nesting of
  these tags (for example, <set copy=<get orig>> will work now).
• Fix sorting algorithm, so triggers with matching word counts will be
  sorted by length descending.
• stream() function can accept a multiline string instead of an array
• Speed optimization by precompiling as many regexps as possible (what was
  especially helpful was to precompile substitution and simple trigger
  regexps), taking the time-to-reply for the default brain from ~0.19s down
  to ~0.04s
• Add support for ! local concat option to override concatenation mode
  (file scoped)
• Fix the regexp used when matching optionals so that the triggers don't match
  on inputs where they shouldn't. (RiveScript-JS issue #46)

Release 1.06 - Nov 25 2014

Changes:

• Change package name from python-rivescript to simply rivescript.
• Change from the GPLv2 license to the MIT license.
• Add compatibility with Python 3.
• Add Unicode support for RiveScript documents.
• Prefer the .rive extension for RS documents over the old .rs extension.
• Track filenames and line numbers when parsing RiveScript documents.
• Add Perl object handler example.
• Add current_user() method accessible from inside an object macro.
• Add unit tests.
• Add deparse() function that dumps the active memory state of the bot.
• Add write() method that writes the active memory state back to disk as a
  .rive file (uses deparse()).
• Bugfix with substitution placeholders.
• Bugfix with the <input> and <reply> tags.
