Overview

ScalaLexer is a hand-rolled structural lexer for Scala source, modelled on Noir::PhpLexer / Noir::CSharpLexer. The Scala analyzers used to strip each line in isolation (strip_non_code_with_state(line, 0, false)), resetting the block-comment depth and multiline-string flag on every line, so route-shaped DSL inside a """…""" triple-quoted string or a multi-line /* … */ comment leaked as phantom endpoints. This lexer threads that state across the whole file once.

Two masked views are produced, both the same length as the source with newlines preserved:

• #masked (structural): strings, comments, triple-quotes and char literals are all blanked — used for brace/paren matching.
• #code: comments, triple-quoted bodies and char literals are blanked, but regular "…" string literals are PRESERVED, because Scala routes are string arguments (path("users")) that the analyzers read back.

Scala specifics handled: nested block comments (/* /* */ */), triple-quoted raw strings spanning lines, regular strings with \ escapes, and 'x' / '\n' char literals (left as code when it is actually a 'sym symbol).
