# smt2parser

This crate provides a generic parser for SMT2 commands, as specified by the
[SMT-LIB-2 standard](http://smtlib.cs.uiowa.edu/language.shtml).

Commands are parsed and immediately visited by a user-provided
implementation of the trait `visitors::Smt2Visitor`.

To obtain concrete syntax values, use `concrete::SyntaxBuilder` as a
visitor:
```rust
let input = b"(echo \"Hello world!\")(exit)";
let stream = CommandStream::new(
    &input[..],
    concrete::SyntaxBuilder,
    Some("optional/path/to/file".to_string()),
);
let commands = stream.collect::<Result<Vec<_>, _>>().unwrap();
assert!(matches!(commands[..], [
    concrete::Command::Echo {..},
    concrete::Command::Exit,
]));
assert_eq!(commands[0].to_string(), "(echo \"Hello world!\")");
```
