I have read the entire PCRE documentation and have not found something that states clearly what I'm looking to do. The documentation says: "By default, PCRE treats the subject string as consisting of a single line of characters (even if it actually contains newlines)." That is what I want to hear, but it is not working out in practice. Testing version 8.32.
Goals: 1. Load a text file into a std::wstring buffer. 2. Have no regard for the concept of "lines". One big string is fine. 3. Use Positive Lookahead to find terms in ANY order. 4. I don't ever care about capturing or using LookBehinds. 5. Any character before or after the query terms is fine. Regex: Thus I have come up with this: (?=.*hello.*)(?=.*world.*) Sample data from file.txt: First line, hello present. Second with world present. Please verify this Solution: However, it only seems to work if I set PCRE_DOTALL. What are the consequences of using this flag? Is there a better way? I don't really want to use the ^$ combo as that is the notion of lines, no? They don't work anyway. -- ## List details at https://lists.exim.org/mailman/listinfo/pcre-dev
