The default lexer context with position and line tracking.
The default lexer context with position and line tracking.
This context tracks:
- The current column position within the line (1-based, resets on newlines)
- The current line number (1-based)
This is the most commonly used context and provides useful information for error reporting. The text field is inherited from LexerCtx.
Value parameters
- line
-
the current line number (1-based)
- position
-
