Empty
An empty lexer context with no extra state tracking.
This is the simplest context that only tracks the remaining text. Use this when you don't need line or position tracking.

Structural fallback for the getter/setter refinement that ctx (see below) types itself with, so that ctx.field += 1 type-checks even when field is an immutable val. The lexer macro rewrites away every such structural access inside a rule before it is compiled, so in practice this is only a safety net; it should never be hit at runtime.

A read-only view of the text still remaining to be tokenized.
Exposed so a custom alpaca.internal.lexer.ErrorHandling instance can inspect the character(s) that failed to match any token rule, e.g. to build a diagnostic message such as unexpected '${ctx.remainingText.charAt(0)}'.
