type Parser ¶

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

Parser parses tokens into an AST using recursive descent.

ARCHITECTURE NOTE: The parser uses error collection (not fail-fast). When an error is encountered, it's appended to p.errors and parsing continues. This allows reporting multiple errors in a single parse, improving UX.

The parser handles Kukicha's "context-sensitive keywords" - words like `list`, `map`, and `channel` are keywords only when followed by `of` in a type context. This lets users use these as variable names in expressions.

func New(source string, filename string) (*Parser, error)

func NewFromTokens(tokens []lexer.Token) *Parser

func (p *Parser) Errors() []error

func (p *Parser) Parse() (*ast.Program, []error)
