+# kdl-schema
+
+[KDL Schema](https://github.com/kdl-org/kdl/blob/1.0.0/SCHEMA-SPEC.md) types and parsing.
+
+## examples
+
+### building a schema
+
+```rust
+use kdl_schema::*;
+let schema = Schema {
+ document: Document {
+ info: Info {
+ title: vec![TextValue {
+ text: "Sample Schema".to_string(),
+ lang: Some("en".to_string()),
+ }],
+ ..Info::default()
+ },
+ nodes: vec![Node {
+ name: Some("name".to_string()),
+ values: vec![Value {
+ validations: vec![Validation::Type("string".to_string())],
+ ..Value::default()
+ }],
+ ..Node::default()
+ }]
+ }
+};
+println!("{:?}", schema);
+```
+
+### parsing a schema KDL
+
+```rust
+#[cfg(feature = "parse-knuffel")] {
+ let schema_kdl = r#"
+document {
+ info {
+ title "Sample Schema" lang="en"
+ description "An example schema" lang="en"
+ author "boringcactus"
+ }
+ node "name" {
+ value {
+ type "string"
+ }
+ }
+ node "age" {
+ value {
+ type "number"
+ }
+ }
+}
+"#;
+ let _matching_document = r#"
+name "Joe"
+age 69
+"#;
+ let schema = kdl_schema::Schema::parse(schema_kdl).unwrap();
+ assert_eq!(schema.document.info.title[0].text, "Sample Schema");
+}
+```
+
+### referencing the schema schema
+
+```rust
+assert_eq!(kdl_schema::SCHEMA_SCHEMA.document.info.title[0].text, "KDL Schema");
+```
+
+## cargo features
+
+- `parse-knuffel` - expose `Schema::parse`, powered by [the `knuffel` crate](https://crates.io/crates/knuffel)
+
+## conditions blocking version 1.0.0
+
+- types actually match the schema (currently I'm omitting several things because the schema schema doesn't use them)
+- ergonomic builder API to define a schema in Rust in a non-ugly way
+- can generate KDL
+- can choose kdl or knuffel as parser
