Introduces cpp/ql/test/library-tests/regex/test.cpp with the Ruby regex
corpus mechanically translated to C++ string literals and wrapped in
std::regex construction calls using fully self-contained in-file stubs
(no #include of any external/standard header).
Stub surface:
std::basic_regex<CharT> constructor(const char*), constructor(const char*, int),
assign(const char*)
std::regex typedef for basic_regex<char>
std::regex_match / regex_search / regex_replace free functions
1:1 corpus mapping from regexp.rb:
- All Ruby /regex/ literals translated to C++ "string" literals
(each backslash doubled: /\d/ -> "\\d")
- Dropped: /#{A}bc/ (Ruby string interpolation, no string-literal form)
- Kept: a{,8}, .*m, \A, \z, \G, \h\H, (?'foo'...) — these are removed
in commits 4 and 5 (keeping them here preserves 1:1 mapping)
Also removes `abstract` from RegExp class in ParseRegExp.qll so that all
StringLiterals are regex candidates (trivial syntactic gate; no dataflow).
.expected generated by:
codeql test run --learn --search-path=. cpp/ql/test/library-tests/regex/
(CodeQL CLI 2.26.1, bundled C/C++ extractor)
All 2 tests passed.
