This makes it hard for people to develop\nlocal customizations on the record (to, e.g., get the sublibraries that hold a monograph),\nthe only option being to build external methods/functions to extract the data\n(e.g., `get_oclcs(rec)`, instead of `rec.oclcs`)\n\nSimilarly, the current MARC::Record implementation is driven largely by the needs of\nthose of us who are more than willing to trade memory use and initialization time\nin order to make many reads from a record slightly faster. If anyone else would rather\nmake different tradeoffs they have no options at all.\n\nThis non-breaking change allows passing in a `record_class:` keyword argument\nto the readers, which will then use that class to build records instead of\na vanilla MARC::Record.\n\n```ruby\n\nclass MyMarc < MARC::Record\n  include \"my_library_stuff\"\n  include \"someone_elses_standard_identifier_stuff\"\nend\n\nreader = MARC::XMLReader.new(\"/path/to/file.xml\", record_class: MyMarc)\nreader.each do |rec|\n  puts rec.oclcs.join(\"\\n\")\nend\n\n```","shortMessageHtmlLink":"Allow passing of custom MARC::Record-derived class to readers"}}],"hasNextPage":false,"hasPreviousPage":false,"activityType":"all","actor":null,"timePeriod":"all","sort":"DESC","perPage":30,"cursor":"djE6ks8AAAAEStcdnwA","startCursor":null,"endCursor":null}},"title":"Activity · ruby-marc/ruby-marc"}
