ExternalLexStates mirrors C tree-sitter ts_external_scanner_states. Rows are external lex state IDs; columns are Python external token indices.

Functions ¶

func DeserializeState ¶

func DeserializeState(s *State, buf []byte)

func SerializeState ¶

func SerializeState(s *State, buf []byte) int

Types ¶

type Delimiter ¶

type Delimiter byte

This state and encoding serve Python-derived external scanners. Keep this file separate from Python registration so a subset does not publish Python metadata when it only includes a derivative grammar.

const (
	DelimiterSingleQuote Delimiter = 1 << 0
	DelimiterDoubleQuote Delimiter = 1 << 1
	DelimiterBackQuote   Delimiter = 1 << 2
	DelimiterRaw         Delimiter = 1 << 3
	DelimiterFormat      Delimiter = 1 << 4
	DelimiterTriple      Delimiter = 1 << 5
	DelimiterBytes       Delimiter = 1 << 6
)

func (Delimiter) EndChar ¶

func (d Delimiter) EndChar() rune

func (Delimiter) IsBytes ¶

func (d Delimiter) IsBytes() bool

func (Delimiter) IsFormat ¶

func (d Delimiter) IsFormat() bool

func (Delimiter) IsRaw ¶

func (d Delimiter) IsRaw() bool

func (Delimiter) IsTriple ¶

func (d Delimiter) IsTriple() bool

type PythonExternalScanner ¶

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

func Bind ¶

func Bind(lang *gotreesitter.Language, bind func(*gotreesitter.Language, func(int, gotreesitter.Symbol)) []int) PythonExternalScanner

Bind uses the caller's positional binder and preserves its diagnostics.

func (PythonExternalScanner) Create ¶

func (PythonExternalScanner) Create() any

func (PythonExternalScanner) Deserialize ¶

func (PythonExternalScanner) Deserialize(payload any, buf []byte)

func (PythonExternalScanner) Destroy ¶

func (PythonExternalScanner) Destroy(payload any)

func (PythonExternalScanner) ExternalScannerASCIIEquivalenceClass ¶

func (PythonExternalScanner) ExternalScannerASCIIEquivalenceClass(b byte) uint8

ASCII digits share every character branch, including string and comment scans.

func (PythonExternalScanner) ExternalScannerForLanguage ¶

func (PythonExternalScanner) ExternalScannerForLanguage(lang *gotreesitter.Language) gotreesitter.ExternalScanner

func (PythonExternalScanner) PreservesStateOnScanFailure ¶

func (PythonExternalScanner) PreservesStateOnScanFailure() bool

func (PythonExternalScanner) RequiresIncrementalPrefixFrontierProof ¶

func (PythonExternalScanner) RequiresIncrementalPrefixFrontierProof() bool

RequiresIncrementalPrefixFrontierProof prevents a changed indentation prefix from transferring a reduction that belongs to the old source.

func (PythonExternalScanner) Scan ¶

func (p PythonExternalScanner) Scan(payload any, lexer *gotreesitter.ExternalLexer, validSymbols []bool) bool

func (PythonExternalScanner) Serialize ¶

func (PythonExternalScanner) Serialize(payload any, buf []byte) int

func (PythonExternalScanner) SupportsIncrementalReuse ¶

func (PythonExternalScanner) SupportsIncrementalReuse() bool

SupportsIncrementalReuse enables checkpoint-authenticated subtree reuse. Python serializes its complete indentation and string-delimiter state, so a reused boundary is accepted only after the live scanner matches its start checkpoint and restores its end checkpoint.

func (PythonExternalScanner) UsesExternalScannerCheckpoints ¶

func (PythonExternalScanner) UsesExternalScannerCheckpoints() bool

type State ¶

type State struct {
	Indents                  []uint16
	Delimiters               []Delimiter
	InsideInterpolatedString bool
}

func (*State) SyncInsideInterpolatedString ¶

func (s *State) SyncInsideInterpolatedString()
