Struct doomdooz_lib::types::Parser

pub struct Parser {
    pub yylexer: Lexer,
    pub static_env: StaticEnvironment,
    /* private fields */
}

A Bison parser, automatically generated from src/parser/parser.y.

Fields

yylexer: Lexer

Lexer that is used to get tokens

static_env: StaticEnvironment

Stack of sets of variables in current scopes. Each stack item represents locals in the scope.

You can use it to pre-define some locals and parse your input as if these locals exist.

For example, you can parse the following code

a = b + c

as

Send(LocalVar(a), "+", LocalVar(b))

by declaring a and b as locals using

parser.static_env.declare("a")
parser.static_env.declare("b")
parser.parse()

Implementations

impl Parser

pub fn parse(&mut self) -> bool

Parses given input. Returns true if the parsing was successful.

impl Parser

pub fn new<TInput>(input: TInput, options: ParserOptions) -> Parserwhere
    TInput: Into<Vec<u8, Global>>,

Constructs a parser with given input and options.

Returns an error if given input is invalid.

pub fn do_parse(self) -> ParserResult

Parses given input and returns:

1. AST
2. tokens
3. diagnostics
4. coments
5. magic comments
