Dataset

@dataDirective

Declares a named dataset — tabular data with named columns, written once and reached from anywhere in the document. Inline, the body is pipe-delimited rows under a header row that names the columns; attached, a CSV file supplies both. Every cell is a string until an attribute type parses it. Reach a column with {{#name.column}} to splice its cells as comma-separated text at compile time, or bind #name.column where an attribute takes a reference.

Attributes

srcImplicit

CSV attachment to fill the dataset from; the file's header row names the columns. Omit it to declare the rows inline in the body instead. Written in the head: @data#survey:plants.csv.The head shorthand supplies it: @data:value

Allowed content

Body { }header and rows, pipe-delimited (inline form only)
