Why getContents considered harmful?

[chshersh]

@kilianovski Input string for getContents can be huge. And since we have strict Text by default, it will store whole content in memory instead of reading in lazily. Having other type for getContents makes API inconsistent and weird.

Any recommendations for a safer/ saner interact?

[chshersh]

@wbadart This depends on your use-case. The default interact for String is lazy which makes it work only for specific use-cases. I recommend reading the following SO question and answer that explains low-level details:

• https://stackoverflow.com/questions/16799755/haskell-interact-function

You can try using interact for lazy Text or lazy ByteString but the documentation doesn't describe the behaviour precisely.

My general advice would be to not use interact at all, and rewrite the application in a different way.

Gotcha. Thanks for the tips!
