Likewise, I was sad when pone's discogs script stopped working due to the recent changes in discog's api output, which led me to scrap my heavily modified version. I used Florian's discogs.inc as my base (thanks @Florian!) to bring back some of the information I liked to include in my tags. Unfortunately, I'm not too familiar with working JSON arrays (e.g., extraartists), but I think I'm getting a hang of it from looking at Florian's work in parsing the tracklist array. Ultimately, I do not have much time due to work and adopted pone's approach, which involves untangling the JSON formatting for extraartists to scrape the data needed for my preferred credits field.
Here's an example that I tacked on my discogs.inc for Credits and Notes fields (these get merged into the Comment tagfield by a separate custom cleanup action):
# Credits
outputto "CREDITS"
gotoline 1
regexpreplace "(?:^.*\"extraartists\"\:\[)(.*$)" "$1"
ifnot "{\"id"
say "Credits ▼"
saynewline
saynewline
regexpreplace "}$" "\],"
regexpreplace "\,\"(images|thumb)\"\:.*?\]" ""
regexpreplace "\,$" ""
regexpreplace ",\"id\":\d+,\"resource_url\":\".*?\"" ""
regexpreplace "\]$" ""
regexpreplace ",({\"name)" "\r\n$1"
replace ",\"tracks\":\"\"" ""
replace ",\"anv\":\"\",\"join\":\"\"" ""
replace "{" ""
replace "}" ""
regexpreplace "\r?\n" ""
regexpreplace "(\"role\":\"[^\"]+\")(\"name\")" "$1<<NEWLINE>>$2"
regexpreplace "\"name\":\"(.*?)\",\"role\":\"(.*?)\"" "$2 - $1"
regexpreplace "<<NEWLINE>>" "\r\n"
regexpreplace " \(\d+\)" ""
sayrest
endif
# Notes
outputto "NOTES"
gotoline 1
regexpreplace "(?:^.*\")(notes\"\:\".*?)(\"\,\"released_formatted.*$)" "$1"
ifnot "{\"id"
say "Notes ▼"
saynewline
saynewline
replace "notes\":\"" ""
sayrest
endif
Of course, this is just a beginning, which will need updates as I come across various edge cases.
