Bardic

Bardic is a Rust toolbox for building procedural narratives at scale.

Features

Text Generation

Bardic provides facilities for procedural text generation through replacement grammars, allowing the construction of prose by composing properties of entities in your system.

For example the grammar:

event_text => {leader_title} left in search of the [artifact]
leader_title => [leader_role] [leader_name] of [leader_homeland]

given the following parameters:

leader_name => Arthur
leader_role => King
leader_homeland => Camelot
artifact => Holy Grail

results in the following expanded text:

King Arthur of Camelot left in search of the Holy Grail

When procedurally-generated properties are used to expand the fields of the grammar, varied text can be generated for entities in your system.

The grammar above can be described using Bardic's RGrammar struct.
