Functions

func Parse

func Parse(reader io.Reader)

Parse the given PKGBUILD reader

Types

type Scanner

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

Scanner scans for tokens

func NewScanner

func NewScanner(reader io.Reader) *Scanner

NewScanner creates a new scanner instance

func (*Scanner) Next

func (s *Scanner) Next() bool

Next scans for the the next token

func (*Scanner) Scan

func (s *Scanner) Scan() Token

Scan for the the next token

type Token

type Token struct {
	Type   TokenType
	Tokens []Token
	Text   string
}

Token encapsulates components needed to track tokens

type TokenType

type TokenType int
