Re: [Haskell-cafe] Ideas on a fast and tidy CSV library

I hadn't yet tried profiling the programme. I actually deleted it a few days ago. I'm going to try to get something new running, and I will report back. On a slightly less related track: Is there any way to use cassava so that I can have pure state and also yield CSV lines while my computation is running instead of everything at the end as would be with the State monad?

Dear All,

Recently I have been doing a lot of CSV processing. I initially tried to use the Data.Csv (cassava) library provided on Hackage, but I found

Have you tried profiling your cassava implementation? In my experience I've found it's quite quick. If you have an example of a slow path I'm sure Johan (cc'd) would like to know about it.

I'm always interested in examples of code that is not running fast enough. Send me a reproducible example (preferably as a bug on the GitHub bug tracker) and I'll take a look.
