BML Markup Language

BML is a simplified XML used as static database, see the grammar using PEG as input for the pest parser.

In contrast to its C++ reference implementation, this Rust implementation parses indents by pushing them on a stack to compare them instead of counting characters (stack-based-indent) and it allows tabulators between attributes (tabular-attributes) and between colons and multi-line data (tabular-colon-data) supporting tabulator-based along with space-based alignments.

Syntax highlighting is trivial, see vim-bml.

Examples

use bml::BmlNode;

let root = BmlNode::try_from(concat!(
	"server\n",
	"  path: /core/www/\n",
	"  host: example.com\n",
	"  port: 80\n",
	"  service: true\n",
	"  proxy\n",
	"    host: proxy.example.com\n",
	"    port: 8080\n",
	"    authentication: plain\n",
	"  description\n",
	"    :Primary web-facing server\n",
	"    :Provides commerce-related functionality\n",
	"\n",
	"server\n",
	"  // ...\n",
	"  proxy host=\"proxy.example.com\" port=\"8080\"\n",
	"    authentication: plain\n",
)).unwrap();

let (name, node) = root.nodes().next().unwrap();

assert_eq!(name, "server");
assert_eq!(node.named("port").next().unwrap().value(), "80");
