Working with CSVs
2 projects | reddit.com/r/haskellquestions | 27 Oct 2021
I haven't used Pandas, so no basis for comparison, but when I need to scrape data from CSVs, I reach for Cassava (https://hackage.haskell.org/package/cassava).2 projects | reddit.com/r/haskellquestions | 27 Oct 2021
I personnaly use cassava which should have everything you need (even though it can be quite obscure some times). I also know about Frames which might reduce some boiler plate at the price of a step up in complexity (disclaimer I've never use it, but it's author is a serious guy so I'm sure this package as some benefits).
[ANN] ttc-22.214.171.124 - Textual Type Classes

I have done a lot of CSV development! I usually use the cassava library, though I have my own library as well. The cassava library uses FromRecord, FromNamedRecord, ToRecord, and ToNamedRecord type classes for parsing and rendering records, and it uses FromField and ToField type classes for parsing and rendering fields. An identifier type like the UserName example above should declare instances for FromField and ToField in order to be used in CSV files. For types that have appropriate Render and Parse instances, I implement general functions named something like parseFieldWithTTC and toFieldWithTTC, which allows me to declare instances as follows:
