Description
This module provides functions for incorporating Goal into a
data-processing project. In particular, this module provides tools for
managing CSV files, and connecting them with gnuplot scripts for plotting.
CSV management is powered by cassava.

CSV
Arguments
| :: FromRecord r | |
| => FilePath | |
| -> IO (Either String [r]) | CSVs |
Load the given CSV file. The .csv extension is automatically added.
Arguments
| :: FromNamedRecord r | |
| => FilePath | |
| -> IO (Either String [r]) | CSVs |
Load the given CSV file with headers. The .csv extension is automatically added.
Export the given CSVs to a file in the given directory. The .csv
extension is automatically added to the file name.
Export the given list of CSVs to a file in the given directory, seperating
each set of CSVs by a single line. This causes gnuplot to the read CSV as a
collection of line segments. The .csv extension is automatically added to
the file name.
Arguments
| :: (ToNamedRecord r, DefaultOrdered r) | |
| => FilePath | |
| -> FilePath | |
| -> [r] | CSVs |
| -> IO () |
Export the named CSVs to a file in the given directory, adding a header to
the .csv file.
Arguments
| :: (ToNamedRecord r, DefaultOrdered r) | |
| => FilePath | |
| -> FilePath | |
| -> [[r]] | CSVss |
| -> IO () |
Export the given list of named CSVs to a file, breaking it into a set of line segments (with headers).
CSV Instances
goalCSVParser :: (Generic a, GFromNamedRecord (Rep a)) => NamedRecord -> Parser a Source #
A generic .csv parser which reorganizes a header name in camel case into
"human readable" text. Useful for instantiating FromNamedRecord.
goalCSVNamer :: (Generic a, GToRecord (Rep a) (ByteString, ByteString)) => a -> NamedRecord Source #
A generic .csv namer which reorganizes a header name in camel case into
"human readable" text. Useful for instantiating ToNamedRecord.
goalCSVOrder :: (Generic a, GToNamedRecordHeader (Rep a)) => a -> Header Source #
A generic .csv order which reorganizes a header name in camel case into
"human readable" text. Useful for instantiating DefaultOrdered.
Util
Runs gnuplot on the given .gpi, passing it a load_path variable to
help it find Goal-generated csvs.
