Conversation
Add extended glob pattern matching gated on shopt -s extglob: - @(pat|pat) — matches exactly one of the alternatives - ?(pat|pat) — matches zero or one - *(pat|pat) — matches zero or more - +(pat|pat) — matches one or more - !(pat|pat) — matches anything except the alternatives Changes: - Lexer: consume extglob OP(...) as single word tokens - Interpreter: add extglob matching in glob_match_impl with recursive backtracking for *, +, ! operators - Works in case statements and [[ == ]] conditionals Adds 15 spec tests. https://claude.ai/code/session_012rzB3FRw7yoQWCG1mxyW7J
