Choco is a markup language for dialogue systems. It works by emitting signals from text into rust via special @-syntax.
Every signal is prefixed with @-character. Signals may contain
- just a prompt (e.g.
@wave) - just a parameter (e.g.
@{ My important param }) - both prompt and parameter (e.g.
@bookmark{into}) - or neither (e.g.
Pay attention! @).
Three signal prompts are taken by Choco. These are bookmark, choice and style.
Branching is easy in Choco. @bookmark{bookmark-name} registers a graph node, and @choice{chosen-bookmark-name} creates an edge between bookmark this choice belongs to and chosen bookmark. For example:
@bookmark{greet}
– Hello, you!
@choice{greet}– Come again?
@choice{bye}– Hi!
@bookmark{bye}
– Well, farewell..
Styling text is done with @style signal. It accepts a mix of shortened to one character style names and prefixes promptless parameter, containing text.
For example,
@style{qbp}@{- Hello, you!}
Style names are slightly opinionated, but you decide how to display a mix of them:
| Char | Style | Note |
|---|---|---|
| p | Panel | i.e. block |
| c | Code |
|
| q | > Quote | doesn't have to be block-quote |
| b | Bold | |
| i | Italic | |
| s | i.e. strike-through |
