Hello, this is Jonathan, I can help you with your question about the error parsing regexp in Go.
The error you are getting is caused by the use of \w in your regular expression. This is an invalid escape sequence in Go, because \w is not a predefined character class <https://stackoverflow.com/questions/6770898/unknown-escape-sequence-error-in-go> 1 <https://stackoverflow.com/questions/6770898/unknown-escape-sequence-error-in-go> . Go only supports the following escape sequences in regular expressions <https://www.bing.com/search?form=MY0291&OCID=MY0291&q=Bing+AI&showconv=1#>2 <https://stackoverflow.com/questions/24836885/go-regex-error-parsing-regexp-invalid-escape-sequence-k> : - \t for tab - \n for newline - \r for carriage return - \f for form feed - \a for alert - \b for word boundary - \B for non-word boundary - \d for decimal digit - \D for non-decimal digit - \s for whitespace character - \S for non-whitespace character - \w for word character (alphanumeric plus _) - \W for non-word character To match a word character in Go, you need to use [[:word:]], which is equivalent to [0-9A-Za-z_]. Alternatively, you can use [[:alnum:]]_, which is equivalent to [0-9A-Za-z]_. So, your regular expression should be: regexp.Compile(`^([[:word:]./]+)/((?:[[:word:]]+)|[*])(.+)?$`) or regexp.Compile(`^([[:alnum:]_./]+)/((?:[[:alnum:]_]+)|[*])(.+)?$`) This should fix the error and allow you to load the plugin successfully. I hope this helps you with your problem. If you have any further questions, please feel free to ask. 😊 On Sunday, September 3, 2023 at 4:47:39 AM UTC-4 Olivier Szika wrote: > Hi, > > Unexpectedly, unicode.Categories is an empty map when it's only used with > a plugin. > I opened a ticket: https://github.com/golang/go/issues/62430 > > Regards, > > Le samedi 12 août 2023 à 18:13:31 UTC+2, Wojciech S.
