Crate smt2parser

Source
Expand description

This crate provides a generic parser for SMT2 commands, as specified by the SMT-LIB-2 standard.

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:

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!\")");

Re-exports§

Modules§

  • concrete
    A concrete syntax tree together with building functions (aka parser visitors) and SEXP-printing functions.
  • renaming
    Utilities for name resolution and renaming of bound symbols.
  • rewriter
    Rewriting of Smt2 values
  • stats
    A demo implementation of visiting traits that counts things.
  • visitors
    The visiting traits expected by the SMT2 parser.

Structs§

  • CommandStream
    Parse the input data and return a stream of interpreted SMT2 commands
  • Position
    A position in the input. Record a position in the input stream.
