[F] bug with json_foreach

[vkostas]

@mp3taglover

there is a bug with standard coverurl setting, if discogs release has multiple covers it adds ALL urls into coverurl.. (e.g. in coverurl you'll get: http://api-img.discogs.com/....http://api-....discogs.com/... instead of just 1 URL)

...........
there is no way to escape from the loop ...

maybe add a break statement for the loop? would be handy thx.

hm, I don't think this is a bug even I am a lot in favor of it. Bug is considered smth delivered not working as described. This is a missing functionality, yes.
There are a couple of solutions Florian could apply unless he finds smth better.

1. New command readoutputto "" It would bring the value of tag already filled before (after outputto "") to the working area. I have requested several times this feature (which I think will increase the power of WS) but I have not seen any reaction yet. Last time requested in this post [WS] HELP !!!.

   # Coverurl
   outputto "coverurl"
   json_foreach "images"
       json_select "type"
       if "secondary"
           readoutputto "coverurl"                      # <<<<<<<<< new code
           if ""                                        # <<<<<<<<< new code
               json_select "uri"
               sayrest
           endif                                        # <<<<<<<<< new code
       endif
   json_foreach_end
   

2. New command json_foreach_exit (as you mentioned) It fits your example but could be insufficient for other cases. E.g. fill the tag only the first time but do not leave the loop.

   # Coverurl
   outputto "coverurl"
   json_foreach "images"
       json_select "type"
       if "secondary"
           json_select "uri"
           sayrest
           json_forech_exit          # <<<<<<<<< new code
       endif
   json_foreach_end</li></ol>
