dossier-typescript

A TypeScript library for lexing, parsing, and validating Dossier.

Dossier Spec

Core Syntax

• A dossier entry uses one of these shapes:
  • identifier: value
  • identifier :: ... ;;
  • identifier: value :: ... ;;
• A dossier without a value uses identifier ::.
• Anonymous dossiers appear at the root or inside arrays.
• Each parent dossier has a unique set of child identifiers.

Example:

person: "human" ::
	name: "John"
	wallet: "open" ::
		currency: "USD"
		value: 294.12
	;;
;;

Values

• Supported scalar values: strings, integers, decimals, floats, booleans, and null.
• Arrays are written with [ and ].
• Non-empty arrays require a trailing comma after every item.

Example:

tags: [
	"field",
	"sealed",
	"archive",
]

meta: [
	waypoint ::
		code: "A7"
	;;,
]

Formatting

• Indentation uses tabs.
• Non-empty dossiers use expanded form.
• Empty dossiers may use inline form: name :: ;;.
• The first :: or [ stays on the same line as the identifier.
• Arrays use expanded form.
• Empty arrays may use inline form: tags: [].

Example:

expedition: "night-run" ::
	title: "Night archive"
	notes: null
	tags: []
	locker :: ;;
	checkpoints: [
		"north",
		"east",
	]
;;
