[RiScript](https://rednoise.org/rita/reference/riscript.html) is a simple, writer-oriented scripting language included with [RiTa](https://www.npmjs.com/package/rita). RiScript expressions, described below, can be included in any RiTa [grammar](https://rednoise.org/rita/tutorials/grammars.html), or run directly via [RiTa.evaluate()](https://rednoise.org/rita/reference/RiTa/evaluate/).

RiScript is a subset of the Dial scripting language, originally created for the Dialogic system (and used in this excellent game). The antlr grammar files for the language are here.

`34:T705,html`

transform	description	alias
articlize()	adds the correct article according to the phonemes	art()
capitalize()	capitalizes the first letter of the phrase	cap()
uppercase()	capitalizes all letters of the phrase	uc()
quotify()	adds (smart) quotes around the phrase	qq()
norepeat()	ensures a choice will never repeat its output	nr()
pluralize()	pluralizes the phrase via the RiTa inflector	s()

Each has a short form (or alias) that may be more convenient for repeated use.

But you can also create your own custom transforms, as described below. ` 35:T18f7, class Editor { constructor (params = {}){ this.value = params.value || "//\nadd code here\n\n\n"; this.theme = params.theme ?

In RiScript, such expressions can involve multiple, possibly nested, choices and transforms, each including randomized elements. But if symbols are evaluated in the traditional way, once their value is set, they will simply repeat when used multiple times in the same script, and the randomized elements will be forever fixed. We saw one way around this above by using [grammars](#grammars). \n\nThe reason this works is that RiTa grammars, by default, use what RiScript calls **dynamic symbols**, which are evaluated *each* time they are encountered (somewhat like a function or closure in typical languages). But you may also want this behavior when you're *not* explicitly using grammars.
