Judge one paragraph at a time

awk -v RS= splits on blank lines. jq gives each paragraph a text field, and filter --field /text sends only that text. Use a sentence splitter for sentences or a parser for code functions.

Arrived a day early. Thank you!

The zipper broke the first time I used it.

Does this come in blue?

The strap snapped on day two.

awk -v RS= '{gsub(/\n/, " "); print}' paragraphs.txt |
  jq -Rc '{text:.}' |
  thinkthen filter 'Is this a complaint?' \
    --jsonl --field /text --batch 1

{"text":"The zipper broke the first time I used it."}
{"text":"The strap snapped on day two."}
