I’m attempting to cobble together a set of regular expressions for use in MP3Tag to convert between different date string formats, such as: June 15, 1974 >>> 15 Jun 1974 15 Jun 1974 >>> 1974-06-15 6/15/1974 >>> 1974-06-15 …and other variations. Due to some of the input and output formats using a…

[image] mazeckenrode: though still hoping for specific pointers to get my RegEx code working in MP3Tag. I think it's currently not possible. You're using features that are part of the Boost-Extended Format String Syntax that are not enabled in Mp3tag's use of Boost::Regex.

[image] mazeckenrode: though the answer by @dano in the former thread is “perl flavor to a large extent”, which doesn’t seem like a definitive answer to me But this is the only answer that can be found. You can test your regular expressions in Konverter>Tag-Tag. The supported operators are …

[image] mazeckenrode: “perl flavor to a large extent”, which doesn’t seem like a definitive answer to me. If you click on the Help - About menu and there on "Credits" you get a list of components/libraries used by Mp3tag. One of them is called " boost::regex " Maybe that gives you a hint?

[image] Which Regular Expression engine and syntax is used by Mp3tag? Support I'm not using Perl (as the Perl engine) in Mp3tag — it's all C++. As regular expression engine I'm using Boost.Regex which has a perl regular expression syntax.

Thanks, all, for the enlightening replies. Didn’t think to look in Help > About > Credits, and my forum search terms apparently weren’t sufficient to locate that authoritative post by @Florian . So now I’ve learned that MP3Tag uses the Boost::Regex library, which is also used by Notepad++, which is …

[image] mazeckenrode: June 15, 1974 >>> 15 Jun 1974 15 Jun 1974 >>> 1974-06-15 6/15/1974 >>> 1974-06-15 If I see that correctly, then ... the first date has a comma, the second has only blanks .. and is the transformation of the first one. The transformation of 1 and 2 should already lea…

[image] ohrenkino: the first date has a comma, the second has only blanks… and is the transformation of the first one. The transformation of 1 and 2 should already lead to the final form. Some explanation is in order: I don’t use these RegEx actions as steps to go from A to B to C. I have var…

[image] Florian: You’re using features that are part of the Boost-Extended Format String Syntax that are not enabled in Mp3tag’s use of Boost::Regex. Ok, thanks, that explains it then. In that case, please consider this a formal request to include those features, if there’s no compelling reas…

In the meantime (while your regular expression doesn't work) you could simplify your modifications with some $replace(%TITLE%,January,Jan,February,Feb,...,June,Jun,December,Dec) commands for the tags you assume this month names. From the help : [image] There are several existing threads about t…

[image] mazeckenrode: please consider this a formal request to include those features, if there’s no compelling reason not to. Unfortunately, there is one compelling reason: the extended syntax has some special characters '$', '\', '(', ')', '?', and ':' which would break existing replacement…
