  1. …-- as the creator of (I think?) the only AWK interpreter written in Go ( https://github.com/benhoyt/goawk ), I was curious. It turns out that if there's only one item in the training data (GoAWK), AI likes to copy and paste freely

  7. You should include qsv ( https://github.com/jqnatividad/qsv ) and goawk ( https://github.com/benhoyt/goawk ) into the CSV section! Goawk got a csv/tsv mode and qsv is loaded with features being developed.
