I have the following code: #include <string> #include <regex> #include <iostream> int main() { std::string s; s += ‘x06’; s += ‘x00’; std::regex r(std::string(1, ‘x06’) + ‘x00’); std::smatch sm; if (std::regex_search(s, sm, r)) { std::cout << "Successn"; return 0; } std::cout << "Failuren"; } On Windows, I get "Success" while on Linux, I get "Failure". ..

Let say I’ve a string of comma separated UUIDs with some additional words as shown below. DATA_TYPE_1(62af4205-fbf8-4961-902e-0b9b21d82a20,1697700f-7bb3-4f7c-83ba-1933b98e05cd,4595ef3f-34e5-4bbe-9c56-26e4e6c84e9f) So the code should return a list of 3 strings in this case consisting the 3 uuids. I tried a code as follows with a vain. std::vector<std::string> ParseUUIDList(std::string& iText) { std::smatch sm; const std::regex pattern("^[0-9a-f]{8}-[0-9a-f]{4}-4[0-9a-f]{3}-[89ab][0-9a-f]{3}-[0-9a-f]{12}$"); //std::regex_match(iText, sm, pattern); ..

Trying to do a regex_replace to convert "C:somethingwin.exe" to "C:somethingwin.exe" : std::wstring path= L"C:somethingwin.exe"; std::wregex pathRegex(L"+d+$"); std::wstring sPath= std::regex_replace(path, pathRegex, std::wstring()); The above doesnt work. I get the same string. Other regexes I tried: "{1}d+$" => unhandled regex_error ".{1}d+$" => works but not quite as narrow as hoped "\d+$" => doesnt work Any suggestions ? ..

I’m using a very nice and simple std::vector<std::string> initializer which takes an input string and regex. It’s similar to a basic split, just it works with regex Group1 matches: static std::vector<std::string> match(const std::string& str, const std::regex& re) { return { std::sregex_token_iterator(str.begin(), str.end(), re, 1), std::sregex_token_iterator() }; } Construction of a vector is done like below: ..

I want to exclude certain regex patterns from linting for readability-identifier-naming. Part of .clang-tidy I’m using: Checks: ‘readability-*’ CheckOptions: – key: readability-identifier-naming.TypeAliasCase value: CamelCase – key: readability-identifier-naming.TypeAliasIgnoredRegexp value: ‘(*_type|*reference|*iterator)’ – key: readability-identifier-naming.TypedefCase value: CamelCase – key: readability-identifier-naming.TypedefIgnoredRegexp value: ‘(*_type|*reference|*iterator)’ However, warnings on those regex patterns are not suppressed. For example, using value_type = T; using ..

I have a regex which by regex101 works correctly: There are 2 matches, as intended. Now I’d like to split the same with std’s regex_token_iterator: const std::string text = "This is a test string [more or less] and here is [another]."; const std::regex ws_re("(?<=[)(.*?)(?=])gm"); // HOW TO WRITE THE ABOVE REGEX IN HERE? std::copy( std::sregex_token_iterator(text.begin(), ..

I was struggling with unicode regex matching with C++ std::regex. I found that the std::regex_search function may return different values on Mac OS and Linux. Here is the sample code. #include "string" #include "regex" #include "iostream" #include "locale" void regex_test() { std::locale::global(std::locale("en_US.UTF-8")); { std::wstring str(L"水"); std::wregex re(L"w+", std::regex::collate); if (std::regex_search(str, re)) { std::cout << "match" ..
