v0.2.0 - Feb 7, 2017

This update focuses on bug fixes and code reorganization.

API Breaking Changes

• rivescript.New() and the Config struct have been refactored. Config
  now comes from the rivescript package directly rather than needing to
  import from rivescript/config.

  For your code, this means you can remove the aichaos/rivescript-go/config
  import and change the config.Config name to rivescript.Config:

  import "github.com/aichaos/rivescript-go"
  
  func main() {
      // Example defining the struct to override defaults.
      bot := rivescript.New(&rivescript.Config{Debug: true})
  
      // For the old `config.Basic()` that provided default settings, just
      // pass in a nil Config object.
      bot = rivescript.New(nil)
  
      // For the old `config.UTF8()` helper function that provided a Config with
      // UTF-8 mode enabled, instead call rivescript.WithUTF8()
      bot = rivescript.New(rivescript.WithUTF8())
  }

• Reply(), SortReplies() and CurrentUser() now return an error value
  in addition to what they already returned.

Changes

• Add ANSI colors to the RiveScript shell (cmd/rivescript); they can be
  disabled with the -nocolor command line option.
• Add new commands to the RiveScript shell:
  • /debug [true|false] to toggle the debug mode (/debug will print
    the current setting of debug mode).
  • /dump <topics|sorted> to print the internal data structures for the
    topics and sorted trigger sets, respectively.
• Separate the unit tests into multiple files and put them in the rivescript
  package instead of rivescript_test; this enables test code coverage
  reporting (we're at 72.1% coverage!)
• Handle module configuration at the root package instead of in the src
  package. This enabled getting rid of the rivescript/config package and
  making the public API more sane.
• Code cleanup via go vet
• Add more documentation and examples to the Go doc.
• Fix @Redirects not working sometimes when tags like <bot> insert capital
  letters (bug #1)
• Fix an incorrect regexp that makes wildcards inside of optionals, like [_],
  not matchable in <star> tags. For example, with + my favorite [_] is *
  and a message of "my favorite color is red", <star1> would be "red" because
  the optional makes its wildcard non-capturing (bug #15)
• Fix the <star> tag handling to support star numbers greater than <star9>:
  you can use as many star numbers as will be captured by your trigger (bug #16)
• Fix a probable bug within inheritance/includes: some parts of the code were
  looking in one location for them, another in the other, so they probably
  didn't work perfectly before.
• Fix RemoveHandler() to make it remove all known object macros that used that
  handler, which protects against a possible null pointer exception.
• Fix LoadDirectory() to return an error when doesn't find any RiveScript
  source files to load, which helps protect against the common error that you
  gave it the wrong directory.
• New unit tests: object macros.
• An internal optimization that allowed for cleaning up a redundant storage
  location for triggers that have %Previous commands (PR #20)
