This version can be pinned in stack with:Frames-0.1.9@sha256:7c4d2a1afd0fbf202a11c4a246ca9ffcba026ff9c60e475bc38b22c260d6abbd,6866

User-friendly, type safe, runtime efficient tooling for working with tabular data deserialized from comma-separated values (CSV) files. The type of each row of data is inferred from data, which can then be streamed from disk, or worked with in memory.



Fixed column type inference bug that led the inferencer to prefer Bool too strongly.

This was fallout from typing columns whose values are all 0 or 1 as Bool.


Re-export Frames.CSV.declareColumn from Frames. This makes it much easier to manually define column types.


Use microlens instead of lens-family-core for demos.


GHC-8.0.1 compatibility

Improved documentation based on suggestions by Alexander Kjeldaas


Fixed bug in Monoid instance of Frame (@dalejordan)

Added frameConsA, frameSnoc, and RecordColumns to help with changing row types.

Initial version pushed to hackage.
