Simple Declarative Language (SDL) for Dart
SDLang is a simple and concise way to textually represent data. It has an XML-like structure – tags, values and attributes – which makes it a versatile choice for data serialization, configuration files, or declarative languages. Its syntax was inspired by the C family of languages (C/C++, C#, D, Java, …).
sdl-dart is built with highly-efficient parser combinators - easy to read, very fluid, and LL(infinity).
import 'package:sdl_dart/sdl_dart.dart';
void main() {
// ...
final sdl = new SDLangParser();
final result = sdl.parse(source);
print(result.value);
} // This is a node with a single string value
title "Hello, World"
// Multiple values are supported, too
bookmarks 12 15 188 1234
// Nodes can have attributes
author "Peter Parker" email="[email protected]" active=true
// Nodes can be arbitrarily nested
contents {
section "First section" {
paragraph "This is the first paragraph"
paragraph "This is the second paragraph"
}
}
// Anonymous nodes are supported
"This text is the value of an anonymous node!"
// This makes things like matrix definitions very convenient
matrix {
1 0 0
0 1 0
0 0 1
}
