Timeline DSL — VS Code Extension
Syntax highlighting for Timeline DSL (.tdsl) files.
Timeline DSL is a domain-specific language for building historical timelines with Wikidata integration.
Features
- Syntax highlighting for all Timeline DSL constructs
- Keywords:
timeline, lane, span, event, event_range, import, map
- String literals, comments (
// and /* */)
- Wikidata entity IDs (
Q123), property IDs (P569), and references (wd:Q123)
- Wikidata expressions:
claim(P571).year, label@ja
- Numeric literals including negative years (e.g.
-221 for 221 BCE)
Example
// Chinese Dynasties Timeline
timeline "Chinese Dynasties" {
unit year;
range -500..2000;
calendar proleptic_gregorian;
}
lane "Qin" as qin { kind dynasty; order 10; }
lane "Han" as han { kind dynasty; order 20; }
span qin -221..-206 "Qin Dynasty" { source wd:Q7183; };
span han -206..220 "Han Dynasty" { source wd:Q7209; };
event qin -221 "Unification of China" {};
// Import from Wikidata
import {
wd:Q7209 as han_entity;
}
map han_entity -> han {
target_type span;
label label@en;
start claim(P571).year;
end claim(P576).year;
}

Install the Timeline DSL CLI to compile .tdsl files:
# Build to JSON IR
