Struct rustlr::runtime_parser::StandardReporter

pub struct StandardReporter {
    pub training: bool,
    pub trained: HashMap<(usize, String), String>,
    pub scriptinopt: Option<BufReader<File>>,
    pub scriptoutopt: Option<File>,
}

these objects implement the ErrHandler trait. They are used in the RuntimeParser::parse_stdio, RuntimeParser::parse_stdio_train and RuntimeParser::train_from_script functions.

Fields

training: bool

trained: HashMap<(usize, String), String>

scriptinopt: Option<BufReader<File>>

scriptoutopt: Option<File>

Implementations

impl StandardReporter

pub fn new() -> StandardReporter

creates default standard reporter, used by parse_stdio (does not train)

pub fn new_interactive_training(existingparser: &str) -> StandardReporter

creates a stdio error handler with interactive training, takes as argument parser file name, to create script for future retraining.

pub fn new_script_training(
    existingparser: &str,
    scriptfile: &str
) -> StandardReporter

creates a stdio error handler that trains (non-interactively) from a previously created script. It’s the user’s responsibility to match the script file with the input source.

impl StandardReporter

pub fn augment_training(&mut self, filepath: &str) -> Result<()>
