The test files (parse.ql, regexp.ql, regexp.rb, *.expected) are also copied verbatim from the Ruby test suite as a baseline reference. This commit does NOT compile against C++: it still imports codeql.ruby.AST and references Ruby AST types (RegExpLiteral, StringlikeLiteral, etc.). The adaptation to compile against C++ is in the next commit. Also adds the codeql/regex dependency to cpp/ql/lib/qlpack.yml and the unreleased change-note at cpp/ql/lib/change-notes/2026-07-21-cpp-regex-tree-view.md. --- .../2026-07-21-cpp-regex-tree-view.md | 4 + cpp/ql/lib/qlpack.yml | 1 + .../semmle/code/cpp/regex/RegexTreeView.qll | 1240 +++++++++++++++++ .../code/cpp/regex/internal/ParseRegExp.qll | 1040 ++++++++++++++ .../test/library-tests/regex/parse.expected | 489 +++++++ cpp/ql/test/library-tests/regex/parse.ql | 27 + .../test/library-tests/regex/regexp.expected | 270 ++++ cpp/ql/test/library-tests/regex/regexp.ql | 11 + cpp/ql/test/library-tests/regex/regexp.rb | 82 ++ 9 files changed, 3164 insertions(+) create mode 100644 cpp/ql/lib/change-notes/2026-07-21-cpp-regex-tree-view.md create mode 100644 cpp/ql/lib/semmle/code/cpp/regex/RegexTreeView.qll create mode 100644 cpp/ql/lib/semmle/code/cpp/regex/internal/ParseRegExp.qll create mode 100644 cpp/ql/test/library-tests/regex/parse.expected create mode 100644 cpp/ql/test/library-tests/regex/parse.ql create mode 100644 cpp/ql/test/library-tests/regex/regexp.expected create mode 100644 cpp/ql/test/library-tests/regex/regexp.ql create mode 100644 cpp/ql/test/library-tests/regex/regexp.rb diff --git a/cpp/ql/lib/change-notes/2026-07-21-cpp-regex-tree-view.md b/cpp/ql/lib/change-notes/2026-07-21-cpp-regex-tree-view.md new file mode 100644 index 000000000000..624c9e50c2de --- /dev/null +++ b/cpp/ql/lib/change-notes/2026-07-21-cpp-regex-tree-view.md @@ -0,0 +1,4 @@ +--- +category: minorAnalysis +--- +* Added an internal C++ regular-expression parse library and tree view targeting the ECMAScript grammar (the default for `std::regex`).

03/21] Commit 2: Adapt Ruby regex library to compile against C++ Changes from verbatim Ruby baseline (Commit 1) to compilable C++: ParseRegExp.qll: - Remove: private import codeql.ruby.AST as Ast - Remove: private import codeql.Locations - Add: private import semmle.code.cpp.exprs.Literal - Change RegExp base: Ast::StringlikeLiteral -> StringLiteral - Replace getText(): removes getConstantValue() Ruby accessor, uses getValue() (C++ StringLiteral.getValue() returns the string content, analogous to Ruby's getConstantValue().getString()) RegexTreeView.qll: - Remove Ruby-specific imports (codeql.ruby.AST, codeql.Locations, codeql.regex.nfa.NfaUtils) - Add: private import semmle.code.cpp.exprs.Literal - Keep: codeql.util.Numbers (for parseHexInt in RegExpEscape.getUnicode()) - Keep: codeql.regex.RegexTreeView (satisfies RegexTreeViewSig) - Change getParsedRegExp: Ast::RegExpLiteral -> StringLiteral - Simplify hasLocationInfo to use re.getLocation() directly with +1 offset for opening quote (approximate; fixed in commits 8-9) - Replace isExcluded: remove hasFreeSpacingFlag(), use none() - Ruby dialect features preserved unchanged (\\A, \\z, \\G, \\h, etc.); dialect shift is commit 5 Test queries: - parse.ql, regexp.ql: replace codeql.ruby.Regexp with semmle.code.cpp.regex.RegexTreeView - .expected cleared (no test.cpp until commit 3) Verified: both queries compile successfully with codeql query compile. --- .../semmle/code/cpp/regex/RegexTreeView.qll | 51 +- .../code/cpp/regex/internal/ParseRegExp.qll | 20 +-

.expected MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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 constructor(const char*), constructor(const char*, int), assign(const char*) std::regex typedef for basic_regex 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. --- .../code/cpp/regex/internal/ParseRegExp.qll | 6 +- .../test/library-tests/regex/parse.expected | 487 ++++++++++++++++++ .../test/library-tests/regex/regexp.expected | 268 ++++++++++ cpp/ql/test/library-tests/regex/test.cpp | 107 ++++ 4 files changed, 867 insertions(+), 1 deletion(-) create mode 100644 cpp/ql/test/library-tests/regex/test.cpp diff --git a/cpp/ql/lib/semmle/code/cpp/regex/internal/ParseRegExp.qll b/cpp/ql/lib/semmle/code/cpp/regex/internal/ParseRegExp.qll index d34ec10eb536..bd7b2544a5b6 100644 --- a/cpp/ql/lib/semmle/code/cpp/regex/internal/ParseRegExp.qll +++ b/cpp/ql/lib/semmle/code/cpp/regex/internal/ParseRegExp.qll @@ -11,8 +11,12 @@ private import semmle.code.cpp.exprs.Literal * A C++ string literal that contains a regular expression term, that is, either * a regular expression literal, or a string literal used in a context where * it is parsed as a regular expression. + * + * All string literals are considered potential regexes for now.

<198982749+Copilot@users.noreply.github.com> Date: Tue, 21 Jul 2026 10:12:21 +0000 Subject: [PATCH 05/21] Commit 4: Curate corpus for C++ ECMAScript; regenerate .expected MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Content-only edits to test.cpp to remove Ruby-only syntax that has no C++ ECMAScript equivalent: 1. Removed: "a{,8}" — Ruby-only "{,n}" no-lower-bound quantifier (ECMAScript requires an explicit lower bound in {n,m}) 2. Removed: second ".*" for /.*/m — mode flags in C++ are construction-site arguments (e.g. std::regex::multiline), not part of the pattern string. This mode variant was the exact same pattern string as r_meta1 so it added no coverage. 3. Removed: "(?'foo'fo+)" — Ruby single-quote named-group form. ECMAScript only supports the angle-bracket form (?...). Left in place for now (removed with the parser in commit 5): \\A, \\z, \\G, \\h, \\H — Ruby-only anchor/escape classes. The POSIX-bracket cases are kept through commit 7. .expected regenerated by: codeql test run --learn --search-path=. cpp/ql/test/library-tests/regex/ (CodeQL CLI 2.26.1) All 2 tests passed. --- .../test/library-tests/regex/parse.expected | 24 ------------------- .../test/library-tests/regex/regexp.expected | 14 ----------- cpp/ql/test/library-tests/regex/test.cpp | 6 ++--- 3 files changed, 3 insertions(+), 41 deletions(-) diff --git a/cpp/ql/test/library-tests/regex/parse.expected b/cpp/ql/test/library-tests/regex/parse.expected index f5e1a63fbd96..08ed7a2c218d 100644 --- a/cpp/ql/test/library-tests/regex/parse.expected +++ b/cpp/ql/test/library-tests/regex/parse.expected @@ -29,11 +29,6 @@ test.cpp: # 35| [RegExpRange] a{4,8} #-----| 0 -> [RegExpConstant, RegExpNormalChar] a -# 36| [RegExpConstant, RegExpNormalChar] a -

nonCapturingGroupStart: remove < from char set (handled by namedGroupStart and lookbehindAssertionStart; was causing mis-tokenization of lookbehind) - namedGroupStart: remove Ruby-only single-quote (?'name'...) branch; keep only ECMAScript (?...) syntax - RegexTreeView.qll: - RegExpCharacterClassEscape: remove h, H (Ruby hex-digit classes); keep d, D, s, S, w, W (ECMAScript set) - RegExpAnchor: change to [^, $] only (remove \A, \Z, \z) - RegExpDollar: change to $ only (remove \Z, \z) - RegExpCaret: change to ^ only (remove \A) - test.cpp: - r_cc3: replace \A[+-]?\d+ with ^[+-]?\d+ (ECMAScript caret) - r_meta5 \h\H: removed (Ruby-only hex classes) - r_anc1 \Gabc: removed (\G not in ECMAScript) -

Single POSIX classes: [[:alpha:]], [[:digit:]], [[:space:]], [[:upper:]], [[:lower:]], [[:alnum:]], [[:print:]], [[:punct:]] - Negated outer bracket: [^[:space:]] - Mixed: regular char + POSIX class [a[:space:]] - POSIX collating symbol [[.a.]] - POSIX equivalence class [[=a=]] - Mixed POSIX + range [[:alpha:]0-9] The existing r_posix1-r_posix4 cases remain untouched. New cases use distinct names (r_posix_alpha, r_posix_digit, etc.) to avoid redeclaration. Generated .expected via codeql test run --learn (CodeQL 2.26.1); all 2 tests pass. The expected output captures the CURRENT (pre-fix) tokenization — commit 7 will change these rows when correct POSIX nesting is implemented. --- .../test/library-tests/regex/parse.expected | 291

"copilot-swe-agent[bot]" <198982749+Copilot@users.noreply.github.com> Date: Tue, 21 Jul 2026 10:22:50 +0000 Subject: [PATCH 08/21] Commit 7: Implement POSIX collating symbol and equivalence class support MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add posixCollatingSymbol([.x.]) and posixEquivalenceClass([=x=]) predicates to ParseRegExp.qll, enabling correct tokenization of all three POSIX bracket atom types inside character classes: - [:name:] — already handled, unchanged - [.x.] — new: posixCollatingSymbol predicate - [=x=] — new: posixEquivalenceClass predicate Refactored: - charSetDelimiter: use inAnyPosixBracket helper (covers all three types) - charSet closing: use inAnyPosixBracket helper - inPosixBracket: updated to cover all three types - simpleCharacter: updated to exclude all three types - namedCharacterProperty: includes posixCollatingSymbol and posixEquivalenceClass - inAnyPosixBracket: new private helper; uses pos in [x..y-1] for QL binding Before this commit (commit 6): [[.a.]] → RegExpCharacterClass([[.a.]) + stray ] (WRONG) [[=a=]] → RegExpCharacterClass([[=a=]) + stray ] (WRONG) After this commit: [[.a.]] → RegExpCharacterClass containing RegExpNamedCharacterProperty [.a.] [[=a=]] → RegExpCharacterClass containing RegExpNamedCharacterProperty [=a=] Regenerated parse.expected and regexp.expected

r_plain: "a+b" — plain, offset 1 (already correct) - r_raw: R"(a+b)" — raw, offset 3 (R"( = 3); currently uses 1 (WRONG) - r_raw2: R"(\s+$)" — raw with metacharacters; currently wrong - r_raw3: R"(\(([,\w]+)+\)$)" — complex raw; currently wrong - r_raw4: R"x(a+b)x" — custom-delimiter raw, offset 4; currently uses 1 (WRONG) - r_wide: L"a+b" — L" prefix, offset 2; currently uses 1 (WRONG) - r_wide_raw: LR"(a+b)" — combined LR"( prefix, offset 4; currently uses 1 (WRONG) - r_esc1: "\\s+" — escape-containing plain; offset 1 (correct) - r_esc2: "a\\.b" — escaped dot; offset 1 (correct) Added std::wregex typedef to stubs (for L"..." and LR"(...)" wide-char literals). New locations.ql query reports per-term: litStartCol, valueStart, valueEnd, termStartCol, termEndCol — restricted to test_locations() function. Generated locations.expected via codeql test run --learn (CodeQL 2.26.1). All 3 tests pass. The expected output captures the CURRENT (pre-fix) columns: raw/prefixed rows show termStartCol = litStartCol + 1 (wrong); plain rows show litStartCol + 1 (correct). Commit 9 changes the raw/prefixed rows to their correct values. --- .../library-tests/regex/locations.expected | 40 ++ cpp/ql/test/library-tests/regex/locations.ql | 29 +

10/21] Commit 9: Fix hasLocationInfo for all string literal forms; fix unicode escape MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit RegexTreeView.qll - hasLocationInfo fix (RULE 4): - Add regexpContentOffset(RegExp re) private helper that computes the correct number of source chars before the first content char, from getValueText(): - Plain "...": offset 1 - L"...": offset 2 (L" prefix) - u8"...": offset 3 (u8" prefix) - R"(...)": offset 3 (R"( opener) - R"x(...)x": offset 4 (R"x( with custom delim) - LR"(...)": offset 4 (LR"() - Uses vt.matches("%R\"%(%") to detect raw strings; finds '(' position - For non-raw, finds '"' position - Replace hardcoded `+ 1` with `+ regexpContentOffset(re)` in hasLocationInfo - Update comment: documents plain/encoding/raw/combined forms, notes that escaped non-raw strings are approximate (mirroring Java/Python) test.cpp: - Fix r_uni: change "\\u{9879}" to "\\u9879" — braced \u{...} is not

From 448ae6af531e09f5ddaf4b15d4940dc1597b86e9 Mon Sep 17 00:00:00 2001 From: "copilot-swe-agent[bot]" <198982749+Copilot@users.noreply.github.com> Date: Tue, 21 Jul 2026 12:16:37 +0000 Subject: [PATCH 11/21] Commit 1: Remove \p{...}/\P{...} named-character-property handling std::regex ECMAScript mode does not support \p{Name}; \p tokenizes as an identity escape. Remove pStyleNamedCharacterProperty and its call sites; namedCharacterProperty now covers only POSIX brackets ([:name:], [.x.], [=x=]) and namedCharacterPropertyIsInverted keeps only the [[:^name:]] case (fixing the offset from start+3 to start+2 for POSIX). Update RegExpNamedCharacterProperty getName/isInverted docs to describe POSIX brackets. Remove the four \p{...}/\P{...} corpus lines from test.cpp; keep a plain [a-f\d]+ case for the class-with-escape shape.

12/21] Commit 2: Fix \0 escape parsing In ECMAScript std::regex, \0 matches NUL. The previous escapedCharacter arms all rejected it: the final arm's `not exists(getChar(start+1).toInt())` guard fails for "0", and the numbered-backref arm excludes 0. Add an explicit \0 case (end=start+2) guarded so the following character is not a digit, mirroring EcmaRegExp.escapedCharacter in PR #22200. Add corpus case "a\\0b" to test.cpp; \0 now parses as RegExpEscape.

The regenerated parse.expected reveals genuine mis-parses that this commit deliberately records (fixes in Commit 6): - unnested [:alpha:] and [:b:] are treated as RegExpNamedCharacterProperty even though POSIX brackets are only valid inside a character class, - [[:alpha:]-z] emits a spurious [RegExpCharacterRange] ":]-z" instead of a POSIX class + literal '-' + 'z'.

"copilot-swe-agent[bot]" <198982749+Copilot@users.noreply.github.com> Date: Tue, 21 Jul 2026 12:24:52 +0000 Subject: [PATCH 16/21] Commit 6: Fix POSIX-bracket mis-parses revealed by Commit 5 POSIX bracket expressions ([:name:], [.x.], [=x=]) are only valid nested inside another character class in std::regex. The three predicates now additionally require that at position `start` we are inside an outer character class, approximated by requiring more non-escaped `[` than non-escaped `]` before `start`. A well-formed POSIX bracket contributes one `[` and one `]` at/after `start`, so the check is unaffected by earlier POSIX brackets. Also stop emitting individual charSetTokens for characters inside a POSIX bracket (`inAnyPosixBracket` guard), which removes the spurious `[RegExpCharacterRange] :]-z` on [[:alpha:]-z]. Post-fix, unnested `[:digit:]`, `[:alpha:]`, and `a[:b:]c` are correctly parsed as ordinary character classes / literal sequences rather than `RegExpNamedCharacterProperty`; and the [[:alpha:]-z] range no longer crosses the POSIX bracket boundary.
