Named capture groups for regular expressions When Visual Studio parses errors and warnings from custom command output, it expects regular expressions in the ErrorRegex and WarningRegex attribute values to use the following named groups: (?<message>...): Text of the error. (?...): Error code...
Regular expression with named capture groups may also be used. The parsed parameters replace existing values. Example: --metadata-from-title "%(artist)s - %(title)s" matches a title like "Coldplay - Paradise". Example (regex): --metadata-from-title "(?P<artist>.+?) - (?P.+)" --...
