Hello, I’ve published the tabreader library / gem version 1.0 that lets you read in tabular datafiles in text in the tabular (TAB) format. Use Tab.parse or Tab.read or Tab.foreach or Tab.open or Tab.new. Or with headers (column names in the first row) use TabHash.parse or TabHash.read and so on. Yes, tabreader uses "1\t2\t3".split( "\t" ) for parsing :-). Happy data wrangling with ruby. Cheers. Prost. PS: The FAQ in the README includes: Q: Why NOT use Csv.read( sep: "\t" )? ++ Q: What’s the tabulator (TAB) format? ++ Q: Why tab? ++ Q: Why NOT tab?
