perl-quote

Perl quote-like operator parsing helpers for extracting patterns, bodies, and modifiers from regex, substitution, and transliteration operators.

Public API

extract_regex_parts(text) -> (pattern, body, modifiers) -- parse qr//, m//, and bare // regex tokens
extract_substitution_parts(text) -> (pattern, replacement, modifiers) -- parse s/// with any delimiter style (lenient)
extract_substitution_parts_strict(text) -> Result<(pattern, replacement, modifiers), SubstitutionError> -- strict variant that rejects invalid modifiers
extract_transliteration_parts(text) -> (search, replacement, modifiers) -- parse tr/// and y///
validate_substitution_modifiers(text) -> Result<String, char> -- validate modifier characters
SubstitutionError -- error enum for strict parsing failures

Handles paired ({}, [], (), <>) and non-paired delimiters, nested delimiter balancing, and escape sequences.

Tier 1 leaf crate with zero dependencies. Used by perl-parser-core for quote operator content extraction during parsing.
