The file koha-tmpl/intranet-tmpl/prog/en/modules/virtualshelves/tables/shelves_results.tt exposes parts of template directives to translation, for example: "\", \"dt_sortby\": %s\"Author\"%s\"Year\"%s\"Call number\"%s\"Title\"%s, " "\"dt_created_on\": \"%s\", \"dt_modification_time\": \"%s\", \"dt_action\": " "\"%s\" }%s,%s %s ] } %s %s %s %s [%%~ action_block = '" or ~%%] %s %s [%%~ action_block = action_block _ ' Such semi-internals make translation errorprone. Translators should not be confronted with tt internals.
Very complex. To resolve this translation issue the help of the original authors is needed.
The way the item search handles generation of the JSON data might be useful here, although it's kind of convoluted.
Still valid. Example: https://translate.koha-community.org/de/translate/#search=dt_modification_time&sfields=source,target&soptions=exact,case
I can't find this string in the templates anymore.
