Method Details

parseFile

public static InterpreterDataReader.InterpreterData parseFile(String fileName)

The structure of the data file is very simple. Everything is line based with empty lines separating the different parts. For lexers the layout is: token literal names: ... token symbolic names: ... rule names: ... channel names: ... A line of two quote characters is a hole and is stored as an empty name, so the indexes stay aligned with the lexer. A blank line still ends the section. The word null is kept as text; older files used it for placeholders. mode names: ... atn: enclosed in a pair of squared brackets. Data for a parser does not contain channel and mode names.
