Declare one binding per column
Type-string parser (exposed for testing)

Description

Record-based DataFrame splices — the IO-agnostic core of the TH family. Splices that read CSV / Parquet files at compile time live in DataFrame.TH.CSV (in dataframe-csv-th) and DataFrame.TH.Parquet (in dataframe-parquet-th).

Synopsis

declareColumnsWithPrefix :: Text -> DataFrame -> DecsQ
declareColumnsWithPrefix' :: Maybe Text -> DataFrame -> DecsQ
typeFromString :: [String] -> Q Type

Declare one binding per column

declareColumns :: DataFrame -> DecsQ Source #

Splice a binding for every column of df, named after the column. Column names that are not valid Haskell identifiers are sanitized (see sanitize).

declareColumnsWithPrefix :: Text -> DataFrame -> DecsQ Source #

Like declareColumns but prefixes every binding name with prefix_.

declareColumnsWithPrefix' :: Maybe Text -> DataFrame -> DecsQ Source #

Like declareColumnsWithPrefix but takes an optional prefix.

Type-string parser (exposed for testing)

typeFromString :: [String] -> Q Type Source #
