func (*Lexer) ScanRawText

func (l *Lexer) ScanRawText(term byte) (string, errlog.LocationRange)

This function is used to scan ASCII-Art text, until it encounters a new line that starts with the character 'term'. The function expands tabulators, assuming a tab-width of 4 characters.

func NewParser

func NewParser(log *errlog.ErrorLog) *Parser

NewParser creates a new parser that reports to the given error log.

func (*Parser) Parse

func (p *Parser) Parse(fileId int, str string) *File

Parse a file. For efficieny, files are identified by a number instead of their path.
