Types

type Parser

type Parser struct {
	// contains filtered or unexported fields
}

func NewParser

func NewParser(lexer *lexer.Lexer) *Parser

Creates a new parser using the given Lexer as a source of input tokens

func (*Parser) ParseProgramFully

func (parser *Parser) ParseProgramFully() (*ast.Program, error)

Parses a full program, terminated by EOF

func (*Parser) ParseProgramOrReactionDefFully

func (parser *Parser) ParseProgramOrReactionDefFully(store *eval.ReactionStore) (*ast.Program, *ast.ReactionPointer, error)

Parses a full program or reaction definition, terminated by EOF

type ParserError

type ParserError struct {
	LexerCurrentLine   int
	LexerCurrentColumn int
	// contains filtered or unexported fields
}

Custom error wrapper which additionally contains information about the state of the lexer when the error occurred. (where in the src code caused the parsing error!)
