strict

The MixOS strict-data format: the grammar of *.conf.mix and *.data.mix files. A document is a JSON-shaped tree (nil, bool, number, string, list, map) with bare keys, optional top-level braces, # / -- comments and trailing commas. It is loaded as data and never executed: anything that could run (a variable, a call, a command substitution, interpolation, a semicolon) is refused with a line-numbered error naming the construct.

The crate has no dependency on the Mix language. It provides:

• parse / parse_file to a Value tree;
• from_str / from_value / from_file into a #[derive(Deserialize)] type, and to_string / to_string_pretty / to_value back out;
• encode / encode_pretty for a Value, in text that reads back unchanged;
• to_json / from_json for consumers that work on serde_json::Value.

Build and test with cargo test -p strict. The grammar tests live in tests/grammar.rs, the serde bridge in tests/serde_bridge.rs.

The source is libs/strict.
