https://bugs.documentfoundation.org/show_bug.cgi?id=135538 --- Comment #14 from Edier Guzman --- Hi, same behaviour here with version 7.2.2.2: Version: 7.2.2.2 Build ID: 20(Build:2) CPU threads: 4; OS: Linux 5.14; UI render: default; VCL: gtk3 Locale: en-GB (en_GB.UTF-8); UI: en-US Calc: threaded After trying to find matches with regular expression '^' in order to put a single quote at the beginning of each cell, Calc will say that there is no match. That is a wrong behaviour, as ^ is a valid regular expression for matching beginnings of strings. -- You are receiving this mail because: You are the assignee for the bug.

Since it requires and matches one digit, not having any in the input (ABC-EFG) will make it fail (legitimately; not thru the artificial limitation). If the input does have digits (ABC1EFG), the pattern will match each in turn. The matches will be length 1 (or more where followed one or more spaces) - therefore LO won't discard them. My problem was specifically about zero-width assertions "(?<=..)", "(?___ Libreoffice-bugs mailing list Libreoffice-bugs@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/libreoffice-bugs

But searching for "\d*" would match everywhere is not actually that useful. Where allowing zero-length matches would be useful is with anchors like in the original request of this bug or the other ones linked in the see also section. -- You are receiving this mail because: You are the assignee for the bug.___ Libreoffice-bugs mailing list Libreoffice-bugs@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/libreoffice-bugs

Works for me with and without the code around nStartOfs/nEndOfs returning "Search key not found" for ABC-EFG. Don't see much benefit from adding a note about zero-length matches to the UI; although it's easy to implement and unobtrusively replacing the "Search key not found" label. Point is that you get the zero result anyway. But no objection to implement this. -- You are receiving this mail because: You are the assignee for the bug.___ Libreoffice-bugs mailing list Libreoffice-bugs@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/libreoffice-bugs

The specific comment is this: // #i118887# ignore zero-length matches e.g. "a*" in "bc" It was a decision made in OpenOffice (I added the link to their bug in the See Also field). So this is intended behavior to avoid the matching-every-position case, not a bug. Whether it should be intended behavior and how to address it is another question. Personally, I tend to think that users searching for regular expressions are knowledgeable about the regex pattern they are providing (or should be) and therefore we should match the pattern as written. -- You are receiving this mail because: You are the assignee for the bug.___ Libreoffice-bugs mailing list Libreoffice-bugs@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/libreoffice-bugs
