Changelog for Frames-0.3.0.2
0.3.0
- Pervasive use of
pipes
for CSV data loading
This provides better exception handling (file handles should be closed more reliably), and offers an interface point for customized handling of input texts. An example of this latter point is working with particular file encodings.
A breaking change is that operations that previously returned IO
values now return MonadSafe
constrained values.
- Adaptation of
Data.Vinyl.Curry.runcurry
to the FramesRecord
type This simply strips the column name information from a row before applying the function fromvinyl
.
0.2.1
-
Refactored to use the
CoRec
type provided byvinyl
>= 0.6.0 -
Fixed bug in typing mostly-numeric columns Such columns must be represented as
Text
. Previously, we strove a bit too hard to avoid falling back toText
resulting in dropping rows containing non-numeric values for columns we crammed into a numeric type. -
Minor optimization of CSV parsing In particular, dealing with RFC4180 style quoting
-
GHC-8.2.1 compatibility
0.1.10
- Added CSV output functions:
produceCSV
andwriteCSV
- Added an Eq instance for the
Frame
type
0.1.9
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
.
0.1.6
Re-export Frames.CSV.declareColumn
from Frames
. This makes it much
easier to manually define column types.
0.1.4
Use microlens
instead of lens-family-core
for demos.
0.1.3
GHC-8.0.1 compatibility
0.1.2.1
Improved documentation based on suggestions by Alexander Kjeldaas
0.1.2
Fixed bug in Monoid
