Weather API

Package rivescript implements the RiveScript chatbot scripting language. RiveScript is a scripting language for authoring chatbots. It has a very simple syntax and is designed to be easy to read and fast to write. A simple example of what RiveScript looks like: This matches a user's message of "hello bot" and would reply "Hello human." Or for a slightly more complicated example: The official website for RiveScript is https://www.rivescript.com/ To test drive RiveScript in your web browser, try the [RiveScript Playground](https://play.rivescript.com/). A common feature in many RiveScript implementations is the object macro, which enables you to write dynamic program code (in your favorite programming language) to add extra capabilities to your bot. For example, your bot could answer a question of `what is the weather like in _____` by running some code to look up their answer via a web API. The Go version of RiveScript has support for object macros written in Go (at compile time of your application). It also has optional support for JavaScript object macros using the Otto library. UTF-8 support in RiveScript is considered an experimental feature. It is disabled by default. Enable it by setting `RiveScript.SetUTF8(true)`. By default (without UTF-8 mode on), triggers may only contain basic ASCII characters (no foreign characters), and the user's message is stripped of all characters except letters, numbers and spaces. This means that, for example, you can't capture a user's e-mail address in a RiveScript reply, because of the @ and . characters. When UTF-8 mode is enabled, these restrictions are lifted. Triggers are only limited to not contain certain metacharacters like the backslash, and the user's message is only stripped of backslashes and HTML angled brackets (to protect from obvious XSS if you use RiveScript in a web application). Additionally, common punctuation characters are stripped out, with the default set being `/[.,!?;:]/g`. This can be overridden by providing a new regexp string literal to the `RiveScript.SetUnicodePunctuation` function. Example: The `<star>` tags in RiveScript will capture the user's "raw" input, so you can write replies to get the user's e-mail address or store foreign characters in their name.
