mps-interpreter
All necessary components to interpret and run a MPS script.
MpsInterpretor uses a non-standard Iterator implementation, so it is recommended to use MpsRunner to execute a script. Since MPS is centered around iterators, script execution is also done by iterating.
MpsInterpretor is misspelt to emphasise that it behaves strangely: after every MPS statement, a None item is returned even when the script is not complete. MpsRunner wraps MpsInterpretor so that this behaviour is hidden when iterating.
use std::io::Cursor;
use mps_interpreter::*;
let cursor = Cursor::new(
"files(folder=`~/Music/`, recursive=true)" // retrieve all files from Music folder
);
let interpreter = MpsRunner::with_stream(cursor);
// warning: my library has ~3800 songs, so this outputs too much information to be useful.
for result in interpreter {
match result {
Ok(item) => println!("Got song `{}` (file: `{}`)", item.title, item.filename),
Err(e) => panic!("Got error while executing: {}", e),
}
}
