Math::DomainError

[tskogberg]

In production we've seen this happen:

The string: "2 st 25 öre 1949,1950.\r\n3 st 1 kr 1943.\r\n4 st 1 kr 1944" will generate an Math::DomainError. It comes from the punkt-segmenter gem and it's a known issue.

A possible fix/workaround for this is to use the fork harrisj/punkt-segmenter and use a trained tokenizer. A code doodle on how that could look can be found here: here.

Code line to reproduce: GoogleTranslateDiff.translate("2 st 25 öre 1949,1950.\r\n3 st 1 kr 1943.\r\n4 st 1 kr 1944", from: "sv", to: "en")

Quick and dirty fix for whomever end up here trying to find solution:

def translate(text:, from:, to:)
  GoogleTranslateDiff.translate(text, from: from, to: to)
rescue Math::DomainError
  GoogleTranslateDiff.api.translate(text, from: from, to: to).text
end
